TTDL is a standalone binary and it does not create any files in user's directory. But at start, it checks for a configuration file - please see example configuration ttdl.toml in user's configuration directory and loads it. Local configuration files are supported as well. Locations where TTDL looks for a configuration file:

current working directory
Linux: ~/.config/ttdl/ttdl.toml
Windows: c:\Users\{username}\AppData\Roaming\ttdl\ttdl.toml
OSX: /Users/{username}/Library/Application Support/ttdl/ttdl.toml

To check in which directory TTDL looks for its configuration file, please refer to the table Features, function name config_dir.

First, TTDL looks for a configuration file in the current working directory. And only if it does not contain ttdl.toml, the application looks for its configuration file in user's directory. Automatic configuration path detection can be overridden with command line option -c or --config. If the option is set in command line TTDL disables automatic detection of the configuration file path.

The configuration file contains options that cannot be set in command line:

default foreground color(usually it is white color for dark-themed terminal). By default, the option is not in the configuration file that means None = terminal default color.
colors for special kinds of todos: overdue, due today, due soon, top priority, high priority, and completed
ranges for cases "due soon" and "high priority". By default both option are disabled. To enable "due soon", set it to the number of days, so todos that are due in equal to or less than that number(except overdue and due today todos) will be displayed with soon color. To enable high priority highlight, set important to a priority - all todos with this priority or higher(except top priority ones) will be displayed with important color.
filename - the path to global todo file (can point to directory, TTDL adds todo.txt automatically if filename is a directory). To override the option, you can set environment variable TTDL_FILENAME or use command line option --local if you need to load todo list from current working directory
creation_date_auto The option defines TTDL behavior when a new todo is added. By default, TTDL adds a todo as is - a user must set manually creation date in the subject. Setting creation_date_auto to true makes TTDL to set today as creation date for all new todos if their subject does not include creation date.

Extra ways to set filenames of active and archived todos

Rules to choose a file which is loaded as todo list at startup (from lowest to highest priority):

Default is a file "todo.txt" in the current working directory
Configuration file option filename in section global
Value of environment variable TTDL_FILENAME
Command line option --todo-file
If option --local is set it overrides all options above and loads "todo.txt" from the current working directory

If any path at steps 2-5 points to a directory then "todo.txt" is added automatically.

Rules to choose a file which is used to store archived todos (from lowest to highest priority):

"done.txt" in the same directory with "todo.txt"
Command line option --done-file. If any path set in command line points to a directory then "done.txt" is added automatically. If the value is only a filename without directory then the directory is inherited from todo list file

Customizing the output

NOTE: The only column that cannot be customized and cannot be hidden is the very first column ID. The ordinal number of a task always goes first.

The default output shows the following columns: marker for done, priority, creation date, finish date, due date, and subject. All dates are displayed as absolute values in ISO format, e.g. "2023-05-19".

There are a lot of way to change the way TTDL displays the task table. The simplest way is to use command-line option --short. The option hides all columns except marker for done and priority.

If you prefer to see how many days left before something or how many days passed some date, use the command-line option --human. The option transforms absolute dates into in 1w(in 1 week) or 6d ago(6 days ago) depending on the current date.

If you want to hide, show, or reorder some columns, use the command-line option --fields or modify configuration option global.fiels. The option is a command-separated list of column names. TTDL displays columns in the same order in which you put them to --fields. Usually the column name and a tag name are the same, but majority of standard columns are exceptions:

Field name	Column displays
`done`	Shows `x` if a task is done, `R` if a task is recurrent, and nothing otherwise
`pri`	Task priority
`ctx`	Task contexts, comma-separated if the task has more than 1 context
`prj`	Task projects, comma-separated if the task has more than 1 project
`created`	Task creation date
`finished`	Task completion date
`due`	Task due date
`thr`	Threshold date (the tag name is `t:`)

If you do not like empty columns, but you do not want to fiddle with --fields every time, you can use the option --auto-hide-cols or set the configuration option global.auto_hide_columns = true. When auto hiding columns is on, TTDL automatically hides the columns which have no values.

The opposite case: you do not want to define --fields every time but you want to display all existing tags in separate columns. Use the option --auto-show-cols or set the global.auto_show_columns = true. When the option is on, first, TTDL traverse through the list of tasks and collects all non-empty tags. Second, TTDL shows all the tags in corresponding columns.

NOTE: custom tags(tags which names start with !) are never shown in separate columns.

When using --fields and auto-show-cols you can notice that some information is duplicated. The first occurrence is in the column, the second one is inside subject text. Sometimes it is helpful, e.g. if you pass --human option, columns with dates will display relative value(1d ago). At the same time, task subject contains the absolute value of the date(2023-05-17). Anyway, most of the time the duplication does not look good. To mitigate the issue, use the option --clean-subject or set the configuration option global.clean_subject. The option takes one of three values:

none - default mode. Nothing is hidden.
all - all duplicated info is removed from the subject (project, context, tags, etc)
tags - only tags are removed from the subject(contexts and projects are always displayed in subject). Sometimes, context or project is a part of the text, so removing them can ruin the message. This mode helps to fix this trouble.

The last option that affects the output, is --always-hide-cols or configuration option global.always_hide_columns. Its value is a comma-separated list of tags that are never shows in their own columns, they are shown only inside subject text.

None of mentioned options are mutually exclusive. They allow you to customize the output in a flexible way. E.g, by setting --fields you define what fields you want to see first and in what order. Adding --auto-show-cols display the rest of columns in "random" order - in order of appearance in the task list.

The options are applied to the output in the following order(in case of all options are enabled):

First, --fields to create the beginning of the table
Second, --auto-show-cols appends the rest of columns
Third, --auto-hide-cols removes all empty columns
Fourth, --always-hide-cols removes the columns that should not be visible
The last, --clean-subject removes from the subject text all tags and values which are displayed in separate columns

Output customization example

Let's assume, todo.txt contains a task:

buy milk @food +house due:2023-07-31 rec:1w count:2

Show the list of tasks with various options (for brevity, I omit the tail of the output):

How to use

Run TTDL with the command line:

ttdl [command] [ID range] [subject] [filter options] [extra options]

Options can be at any position. ID range and subject are optional but if you are going to use both, ID range must go first.

If a non-option starts with + or @, the option is considered as a filter by project or context respectively. Command line can contain as many projects and contexts as needed. In this case, all items of the same group are combined with OR. Example: if you execute ttdl list +myproj +demo @docs, it displays all todos that belongs to either myproj or demo, and have docs context.

If the first non-option word contains only digits and dash character, it is treated as a single ID(only digits) or ID range(digits with a dash) or ID list(numbers separated with comma). ID is 1-based: a number between 1 and the number of todos in the entire list. It is OK to use ID out of that range: IDs that are greater than the number of todos or lower than 1 are skipped. So, e.g., if you want to remove all todos starting from 10th todo, you can run the command ttdl remove 10-999999 -a - -a to delete both completed and incomplete todos.

The second non-option(or the first one if ID range is not defined) is a subject. Subject's usage depends on command:

add - it is an entire text for a new todo (including projects, contexts, due date, recurrence);
edit - it is an entire new subject for the first selected todo;
for the rest commands it can be either a substring(case-insensitive search) or a regular expression to search in the todo's subject, projects, and contexts - depends on the option --regex.

NOTES:

All dates are entered and displayed in format - YYYY-MM-DD(4 year digits - 2 month digits - 2 day digits, or ISO 8601 date format)
Recurrence is defined in format 'the number of intervals' + 'interval type' without a space between them. Interval type is one of d - days, w - weeks, m - months, y - years. Example: to add a todo with your friend's birthday(let's assume today is 10th of April) use the following command ttdl add "best friend birthday due:2019-04-10 rec:1y". After the birthday passes, just execute ttdl done <todo-ID> and it will change its due date to 2020-04-10
Recurrence special case: if you set due date to the last day of a month and interval is a month or longer then the next due date will always be the end of the months. Example: a todo pay credit due:2019-02-28 rec:1m after executing ttdl done ID turns into pay credit due:2019-03-31

Recurrent tasks

Sometimes you need to create a task that you have to do periodically - a recurrent task. To make a task recurrent, set the task due date and define a recurrence interval using tag rec:. Please note that a recurrent task must contain a due date, otherwise the recurrence tag is ignored.

A recurrence interval is an integer number followed by an optional interval type:

Interval type	Meaning
(nothing)	the number of days
`d`	the number of days
`b`	the number of business days (Sundays and Saturdays are skipped when counting)
`w`	the number of weeks
`m`	the number of months
`y`	the number of years

Examples: rec:1y - repeat the task every year, rec:2w - repeat the task every two weeks.

A bare recurrence defines a non-strict interval. You can make the recurrence strict by putting a symbol + right before the number: rec:1w - non-strict, rec:+1w - strict. Strictness affects on how TTDL calculates the next due date after completing the current task:

Strict - the next due date depends on the current due date: next due date = current due date + recurrence interval. This mode is useful to track birthdays or regular payments that must be paid by a certain day of month
Non-strict - the next due date depends on the current date: next due date = today + recurrence interval. This mode is useful to track things that have relaxed due date but the task should be done within certain limit of days. Example: you have to mow your lawn at least once a month. So you set non-strict interval rec:1m. Then, even if you mow your lawn a few days before the due date, completing the task moves the due date to exactly 1 month ahead of today. That helps you to keep you lawn nice and never mow too late.

More about recurrent task completion in the section "Completion of recurrent tasks".

Example

Let's assume today is 2023-11-20. In the todo list there are two tasks:

pay credit card due:2023-11-29 rec:+1m
mow lawn due:2023-11-29 rec:1m

Both tasks have the same due date, but different strictness. Let's complete both tasks. The todo list now contains the following lines:

pay credit card due:2023-12-29 rec:+1m
mow lawn due:2023-12-20 rec:1m

The strict task moved its due date to a month ahead of its previous due date. White the non-strict task now have the due date exactly in a month from the current date.

Marking task completed and uncompleted

When you complete a task and you do not want to see it in the default output any longer, mark the task 'done' with the command ttdl done ,ID>. If you have completed an incorrect task by accident, you can get it back with the command ttdl undone <ID>. Where ID is the same that you used for ttdo done command, because marking a task completed does not change its ID.

Hint: to remove an invalid task use ttdl rm. This command may change IDs of all or a few tasks. The command ttdl rm is irreversible.

Hint: after some time, your todo.txt can grow long and can be full of completed tasks. You can use ttdl archive to move all completed tasks to done.txt. It may make TTDL faster.

For majority of cases it is all any user should know about completing and uncompleting tasks. But there are two special cases when completion can work differently: for tasks with priority set, and for recurrent tasks.

Completion of recurrent tasks

When you complete a recurrent task, it marks the old one as done and creates its clone with new due date. So, if you uncomplete the task, you will end with two similar tasks in your todo list. They differ only by their due dates. You should manually remove a duplicated task with ttdl rm.

There is a special case for a recurrent task when the task's due date(for strict recurrence) or today's date(for non-strict recurrence) is the last day of a month and the recurrence interval type is either m(month) or y(year). In this case, the next due date always is the last day of a new due date's month.

Example for strict recurrence: when completing a task pay credit card due:2023-02-28 rec:+1m, the new due date is due:2023-03-31 because 2023-02-28 is the last day of February.

Example for non-strict recurrence: if today is 2023-02-28 and you complete a task pay credit card due:2023-02-25 rec:1m, the next due date of the task is due:2023-03-28 because today is the last day of a month - of February.

Tasks with priority

Default TTDL behavior is just prepend x to the task subject when the task is done. Completed tasks in default mode keep displaying their priorities in the priority column as regular tasks do. If you do not want to see priority column filled with anything(and do not want to colorize done tasks by priority) for completed tasks, tune up the TTDL configuration.

Either change ttdl.toml configuration file: section global, the option priority_on_done or pass command-line option priority-on-done. Available modes:

keep - use the default mode, when a completed tasks keeps showing its priority
move - on completion the priority moves after task completion date. So, the priority becomes part of task subject but is now shown in the priority column
tag - on completion the priority is set to none, but a new tag with priority value is appended to the subject. Example: (A) buy milk becomes x buy milk pri:A in this mode
erase - just set priority to None

NOTE: do not forget to pass the same command-line option value when you want to uncomplete a completed task. All modes above, except erase, are reversible and correctly restore the task priority when you uncomplete the task.

Output example

# D P Created    Finished   Due        Threshold  Subject
----------------------------------------------------

----------------------------------------------------
3 todos (of 3 total)

Columns:

# - order number of a todo
D - 'Done', it is empty for an incomplete regular todo, 'x' for a completed todo, and 'R' for recurrent todo
P - priority (from A to Z, empty value means no priority)
T - marks an active todo - a todo which has its timer running to track time spent on it

Filtering

TTDL allows operations on a range of todos. A range is defined either by todo IDs or by todo attribute values. The filters can be used to limit displayed todos with some condition, or to edit or done a group of command. E.g., you can mark done all todos of a project using a single command.

All examples below are for list command, but filter can be used for more commands, like done and edit.

Filter by IDs

If the first argument after a command is a number-like, TTDL treats it as todo ID or todo ID list. Supported ID formats:

ttdl list 5 - a single todo ID, lists a single todo with ID = 5(if it is incomplete)
ttdl list 2-4 - a range, show all todos from 2nd to 4th(inclusive)
ttdl list 2,4 - a list of IDs, show two todos(if they are incomplete): only 2nd and 4th ones

Filter by priority

Priority filter is set with --pri argument. Available filter kinds:

ttdl list --pri=none - show all incomplete todos that does not have priority set
ttdl list --pri=- - the same as above
ttdl list --pri=any - show all incomplete todos that have non-empty priority
ttdl list --pri=+ - as above
ttdl list --pri=# - where # is a low case Latin letter between a and z, show all incomplete todos that have the same priority
ttdl list --pri=#+ - where # is a low case Latin letter between a and z, show all incomplete todos that have priority # or higher

Filter by recurrence

ttdl list --rec=none - show all non-recurrent todos
ttdl list --rec=- - the same as above
ttdl list --rec=any - show all recurrent todos
ttdl list --rec=+ - as above

Filter by project, context, and tag

Free CLI arguments

Any free command-line argument starting with + is a project name, and starting with @ is a context. A command can contain any number of project names(the same true for contexts), in this case the filter includes all todos that contains any of listed projects names. Please note, that while passing a few contexts means "select todos with any of provided contexts", passing a few project names and contexts at the same time means "select todos with any of provided project names and any of provided contexts".

Project names and contexts support basic matching. Append or prepend * to project name to match projects which names ends or starts with the word.

ttdl list +proj - show all incomplete todos that belong to project proj
ttdl list @ctxA @ctxB - show all incomplete todos that have either context ctxA or context ctxB
ttdl list +projA +projB @ctx - show all incomplete todos that belong either to project projA or to project projB, and have context ctx ((projA ∨ projB) ∧ ctx)
ttdl list +*clientA - show all incomplete todos which project names ends with clientA
ttdl list @car* - show all incomplete todos which have a context starting with car

To exclude todos containing certain project or context, prepend -(minus sign) before + or @:

ttdl list +projA -@ctx - show all incomplete todos that belongs to project projA and do not contains context ctx. (projA ∧ ¬(ctx))

Classic CLI options

Besides using + and @ to indicate project and context titles, the application supports classic CLI options to set the list of values for a filter:

--project - filter by project title
--context - filter by context name
--tag - filter by tag name

All options accepts a comma-separated list of names (and/or patterns). If any option value matches any record value, the record is displayed.

Special values:

none - select records that do not have any values (--context none - records without any context)
any - select records that have at least one value (--project any - records that belong any project)

Any item can be a full name or a pattern to match as it is described in the previous section.

It is possible to exclude todos that contain given projects or contexts from the output. Minus sign - marks items to exclude:

ttdl list --project projA --context "any,-ctxB" - list all todos that belong to project projA and have any context except ctxB. ({∀x | (x ∈ projA) ∧ ¬(x ∈ ctxB) })

Filter by date

All date-like fields(due, threshold, creation, finish) support filtering with a date range as well as a single date. Ranges are always inclusive. Start and end of a range are separated with either .. or :. A range can be "open": in this case it is a single value with appended or prepended range separator. For a closed range, the order of the range end is arbitrary: TTDL automatically exchanges beginning and end if needed. Ranges support only relative dates (positive for dates in the future and negative for dates in the past) or one of special dates.

Relative dates is a list of numbers followed by suffixes (d - days, w - weeks, m - months, y- years) without separator. E.g., 1y in a year; 2m1w in two months and a week; -10d - 10 days ago.

Special dates are:

none - a date is unset; the value can be used as a single value or as only one end of a range. In latter case the filter works as two filters combined: an open range with a real date, and all todos that have the date field empty
today, tomorrow, yesterday - their meaning is clear
first - first day of the next month
-first - first day of this month or the previous month(in case of today is the 1st)
last - last day of this month or next month(in case of today is the last day)
-last - last day of the previous month
day-of-week - a full name of a day of week or abbreviated to 2 or 3 first letters, the nearest day-of-week in the future(it is never today)
-day-of-week - a full name of a day of week or abbreviated to 2 or 3 first letters, the nearest day-of-week in the past(it is never today)

Use the following command-line options to filter by:

due date --due
threshold date --thr
date of creation --created
completion date --completed

Field threshold is the only field with a specific default value. All other fields have empty default value which means the filter is off. The default value of threshold is inclusive range [none..today]. TTDL by default hides tasks that has threshold date and the threshold date is tomorrow and later.

Examples (note the difference between ranges and single values):

ttdl list --due today - show all todos that are due today
ttdl list --due ..today - show all todos that are due today or overdue
ttdl list --due today.. - show all todos that are due today or any day after today
ttdl list --due today..tomorrow - show todos that are due only today or tomorrow
ttdl list --due tomorrow..today - the same as above
ttdl list --completed -1w.. -a - show todos that were done within the last 7 days(a week from today)
ttdl list --completed -first.. -a - show todos that were done this month(or the previous month if today is the 1st)
ttdl list --due -first..last -a - show todos that are due this month(including overdue ones); in corner cases(today is the 1st or the last day of month) it shows todos for 2 months range instead of a month range
ttdl list --created -mon.. - show todos that were created this week(or the previous week if today is Monday)
ttdl list --created -mon - show todos that were created last Monday
ttdl list --due -2d..2d - show todos that are either slightly overdue(1-2 days overdue) or must be done within 2 next days
ttdl list --due none - show todos with undefined due date
ttdl list --due none..tomorrow - show todos that are overdue, due today or tomorrow, and with empty due date
ttdl list --due tomorrow..none - show todos that are due tomorrow or further in the future, and with empty due date

Global filter by a substring

All filters above works only for a certain todo attribute, but it is possible to filter with a simple substring or regular expression. In this case, TTDL looks for the substring everywhere: in subject(description), contexts, and projects. To do this, just pass a bare substring as the first argument after a command. Note the difference between project/context filter and a simple substring one: in the latter case * means a character *, not anything before or after substring. Use command-line option -e to enable fuzzy regular expression based filter.

ttdl list car* - show all incomplete todos that have substring car* in subject, project or context
ttdl list car.* -e show all incomplete todos which project, context or subject matches regular expression car.*

Supported commands

The list of available command is short but the commands are powerful. All commands support group operations and dry run mode, except add command that adds a new todo one at a time. Please, refer to section "Examples", it provides a handful of useful examples of how to filter and modify todo list.

The application determines which command to execute with the following rules:

If the command does not contain any free arguments, TTDL executes list command
If the first free argument is a command, TTDL executes it
In all other cases TTDL executes add command

The rules above allow a user to omit the most used commands add and list. At the same time, the way is error-prone because every typo in command results in adding a new undesirable todo. E.g., if you type ttdl del 15, TTDL, instead of removing todo at 15 position, adds a new todo with message del 15. To avoid such cases and make TTDL command-line check stricter, either add strict_mode = true to section global or pass --strict in command-line. It disables the rule number 3 and TTDL will always require a valid command as the first argument, if there are at least one exists. In strict mode, ttdl del 15 returns the error "first argument must be a command".

Commands:

add - add a new todo;
list - show list of todo items. By default it displays all incomplete todos;
done - mark selected todos completed. If a todo is recurrent and contains due or threshold date(or both) the todo is marked completed and new one is created with due and threshold dates moved to the future;
undone - remove finished mark from completed todos;
remove - deletes the selected todos;
clean - moves completed todos from main file to done.txt. The file done.txt is created(if it does not exist) in the same directory where main todo list file is located. By default, the command also removes all empty todos;
edit - modify one or few properties for the selected todos. One exception: modifying todo's subject changes only the first selected todo, others are skipped;
append - adds a text to the end of the selected todos (space between old text and new one is added automatically);
prepend - inserts a new text at the beginning of the selected todos (space between old text and new one is added automatically);
start - activate todo's timer;
stop - stop todo's timer and update time spent on the todo;
stats - display todo statistics: total number of todos, done and overdue ones, spent time, and detailed statistics grouped by project and context.
postpone - push task's due date (modifies only incomplete tasks with due date defined), argument is the number of days/weeks/months/years to push the date in format: single digit and d/w/m/y without a space between them
listprojects - show list of all project tags. Filters used by "list" are supported;
listcontexts - show list of all context tags. Filters used by "list" are supported;

Most of the commands can be abbreviated. Please refer to built-in TTDL help to get a list of full command names and their aliases.

All commands(except listcontexts and listprojects) skip hidden tasks by default. To include hidden tasks, use --hidden option. See section tags for details.

NOTE: done moves a recurrent todo's due date to the next one, but it does not check if the new due date is in the future (it is by design). So, if a monthly task is 2 months overdue, you have to execute ttdl done ID two times to push it to the incoming month or manually set a new due date with the command ttdl edit ID --set-due=YYYY-MM-DD.

Calendar

By default, the list of todos is displayed as a table. Command-line switch --calendar=<range> allows you to peek what is on your plate in a convenient way. The range can be either a single value or a date interval. In case of a single value, the calendar always includes today's date. Interval values, like recurrence, denote how far in the future or or in the past (negative value) the first or the last date of the range. The calendar displays only dates on which you have something due, i.e, the calendar filters only todos that has due tag. The full range form for a single value is number + range type, e.g. 2w - show this and the next week. The range can be negative. In this case, TTDL displays the past weeks. E.g, --calendar=-2w prints out the current and the previous week. For an interval, the range must be in a form number + range type .. number + range type, e.g. -2m..2m - shows from the previous month up to the next month.

Note: when printing by full weeks and months, numbers 1, -1, and 0 works the same and always shows only the current week or month. So, --calendar=1w and --calendar=-1w both display the current week.

Supported range types:

d - days (in a range -100..=100)
w - weeks (in a range -16..=16)
m - months (in a range -24..=24)
y - years (in a range -2..=2)

Also you can use some short-cuts:

if you do not specify a number, it is defaulted to 1. E.g, --calendar=m and --calendar=1m is the same
if you omit range type, it defaults to d. E.g, --calendar=10 means --calendar=10d.

In w and m modes the displayed interval always starts from the first weekday of a week or from the first date of a month, and ends with the last day of a week or a month respectively. E.g, if today is 2022-07-10 and you request --calendar=1m, TTDL outputs the calendar for the entire July: from 2022-07-01 to 2022-07-31. If you want to display exactly one months starting from today, mark the range strict by prepending +: --calendar=+1m for today's date 2022-07-10 prints the calendar from 2022-07-10 to 2022-08-09.

Note: in strict mode --calendar=1w and --calendar=-1w are not equivalent. The former displays 7 days starting with today. The latter prints out 7 days ending with today.

Color legend:

green foreground - week number (it is ISO week number: https://en.wikipedia.org/wiki/ISO_week_date)
regular Black and White colors - "empty" day when you do not have any todo due
Blue background - today's date
Magenta foreground - on this day you have one todo due
Red foreground - this day has more than one due todo

Example:

In the picture:

Today's date is 23rd of April
There is one todo is due on 25th
There are more than one todo that are due on 27th

Hashtags

Sometimes you need to add one or few extra attributes to a todo, but you do not want to introduce any new contexts or projects. Tags do not work in this case as they require value: you cannot create a tag with empty value. To deal with it, use hashtags. Hashtags is a todo words that start with the symbol #. Example: in a todo buy tickets to #hockey game there is one hashtag #hockey.

Use command-line options --hashtag to filter todo list, --set-hashtag to add new hashtags, --del-hashtag to remove hashtags, --repl-hashtagto replace existing hashtags. The command --repl-hashtag does not append a new hashtag if the todo does not include the hashtag to be replaced.

Time tracking

TTDL version 0.5.0 introduced time tracking feature. It consists of two new commands start to activate time tracking for a given todo, and stop to stop time tracking and update todo's time taken.

The list command adds an extra column Spent that displays total time the todo has taken by the current time.

Statistics

Command stats displays general statistics followed by detailed one. If you need only general one use option --short.

General statistics includes the total numbers of all todos, completed, overdue, recurrent todos, and todos that missed threshold date. For the all numbers, except the total number of all todos, the percentage of all todos is displayed in parentheses. Example:

Total todos:          8
Done:                 1 (12%)
Overdue:              2 (25%)
Recurrent:            1

Detailed statistics groups all todos by projects and contexts and prints the subtotals for all of them. Note: because of todos can have no project or have more than one project or context, the total number of all todos is usually not equal to sum of all subgroups. Example:

Project         Context    Total      Done       Overdue    Spent
                              8(100%)    1( 12%)    2( 25%) 3.1m
-----------------------------------------------------------------
chapelshelving                2( 25%)    1( 50%)
                chapel        1( 50%)    1(100%)
                shelve        1( 50%)
-----------------------------------------------------------------
myproj                        1( 12%)               1(100%)
                bug           1(100%)               1(100%)
                ui            1(100%)               1(100%)

Notes

The first line with number is a grand total for the entire todo list
In the example above, there are total 8 todos, but only 3 of them have project tags. And myproject project has only one todo with 2 context tags
For project headers (lines which have some project and empty context) the percentage is calculated from all todos, for context totals the percentage is calculated from project total todos
Done and overdue percentage is always calculated from the total of the current line
Spent time adds low-cased letters for time spans less than a day (s - seconds, m - minutes, h - hours), and upper-cased letter for longer spans (D - days, M - months, Y - years).

Custom formatting

The feature is introduced in version 0.8: when executing command list TTDL may call an external application (a "plugin") to transform the description and/or tags. If the plugin finishes successfully and its output is valid JSON string, TTDL combines values from the output and prints it instead of default description. Only description can be changed by plugins, other columns like "priority" are fixed ones.

A plugin is a executable shell script or binary with name that follows TTDL rules. Every plugin receives a single argument - JSON as a string, a plugin must print modified or original JSON to standard output.

If any plugin does not exist, fails or returns invalid JSON, TTDL prints the error to standard error output and displays the unchanged original todo description. Otherwise, TTDL joins description and tags, and prints the result.

A todo can contain any number of plugin "calls". They are executed in order of appearance in original description. The result of a current call is passed to the next plugin only if the next plugin name is still in the result - a plugin can remove any tags in the result to make TTDL ignore the other plugins. So, any plugin can disable any other plugins if it removes their tags from the result.

How to enable custom formatting

To enable custom formatting, a todo must include at least one tag which name starts with symbol !. The tag name without ! is the plugin name(and the last part of the file name to call). By default The full name of the file to execute is ttdl- + plugin name. A configuration file contains settings in global section that affects file name:

script_ext - value is used as a file name extension. If the value does not start with '.', the dot is added automatically. Default is empty value - no extension is added. Example: for !tagname:value and script_ext=sh, the script name is tagname.sh;
script_prefix - its value is added before the tag name. It makes possible to, e.g., keep scripts in a separate directory or create a subgroup of scripts. Another usage is for Windows PowerShell: executing tagname.ps1 may fail, because PowerShell wants a user to explicitly say that the script is in the current directory, so you have to set script_prefix="./" to be able to run PowerShell scripts from the current directory. Do not forget to add / at the of the prefix if it is a directory name - TTDL cannot decided automatically if it is a part of filename or a directory.

Related configuration setting defines what shell executes the script:

shell - sets the shell to execute a binary/script. If not set, TTDL uses ["cmd", "/c"] on Windows, and ["sh", "-cu"] on other OS. If you want to use PowerShell on Windows, change the value to ["powershell", "-F"];

Plugin interaction

TTDL pipes a JSON with tags and optional items of a todo that is going to be displayed to a plugin's standard input. A plugin must read STDIN and after processing the JSON, the plugin must print the result to STDOUT in the JSON format. If a plugin does not need to change anything, it must print it as is. If any plugin fails to execute or produces invalid JSON, the error is printed to standard error and the original todo text is displayed.

The first script always gets JSON with all todo's tags and optional fields. Three obligatory fields in the first request(a plugin may remove any of those fields):

description - original todo's description that TTDL would print by default, plugins can modify it;
optional - original todo's optional elements (done, pri, created, and finished);
specialTags - an array of all tags and their values extracted from the todo. NOTE: if a currently running plugin removes a tag that belongs to a plugin that have not run yet, that plugin will be skipped because its tag is missing in specialTags at the moment when the plugin is going to run.

All the next plugins receive a JSON returned by a previous plugin. A plugin must return the modified or original JSON by printing it to standard output. TTDL constructs and displays the modified description returned by the very last plugin. If the final result includes any field it is displayed as is from the JSON, otherwise the original value is printed with default formatting. That makes it possible to, e.g., change "done" mark and replace default x with √, or you can format dates using your native language(e.g., display 10 Sep instead of 2020-09-10).

A plugin may add or remove any fields in resulting JSON, that allows plugins to communicate. The only requirement is that the result should include all fields above.

Notes

While it is OK to set any value to an existing field, the output is limited with the current column width (only description is displayed in full). E.g., if a plugin changes value of created to 12 December 2019, in terminal TTDL prints either first 10 (default settings) or 8 characters(when relative dates are enabled).
All dates passed to the first plugin in JSON are always in format YYYY-MM-DD for easy parsing. So, even if relative dates are enabled, a plugin gets in default format.
All values presented in result JSON are printed as is, while all missing values are printed with current format settings.
Removing a tag from specialTags hashmap does not remove the tag from the subject. If you want to remove a tag, set its value to an empty string.

Example

Let's assume, the configuration has option script_ext = ".ps1", and there is the following line in todo.txt:

# D P Created    Finished   Due        Subject
-----------------------------------------------
1                           2023-06-15 fix bug due:2023-06-15 spent:40 !hidedue:abc
-----------------------------------------------
1 todos (of 1 total)

We want to do a few things when a todo contains !hidedue tag:

a) remove due tag and !hidedue tags; b) change spent tag value to 0; c) add a new tag status with value fixed

Let's create a powershell plugin to fulfill the task.

TTDL detects a tag with leading ! and the plugin engine kicks in. The tag name is !hidedue. The script name is build from the tag name without character !, script_ext, and script_prefix. All plugin names must start with ttdl-. The default value for script_prefix is ./. It makes the script name ./ttdl-hidedue.ps1.

DISCLAIMER: I am no powershell expert. That is why I believe the script can be made simpler and shorter. But the script does its job and it is good enough to be a starting point.

The content of the ttdl-hidedue.ps:

# TTDL sends every task one by one as a JSON to a script through a pipe.
# In powershell opened STDIN pipe is access via system variable `$input`

# 1. Read the STDIN and convert it into JSON
$obj = $input | ConvertFrom-Json
$do_fix = 'false'
# 2. JSON objects are PSObjects, let's convert them into Powershell hashtables
$obj.specialTags = $obj.specialTags | ForEach-Object {
	$h = @{}
	$_.PSObject.properties | ForEach-Object {
	  $h[$_.Name] = $_.Value
	}
	$h
}
# 3. Check if a task includes the tag '!hidedue'. Its value must be non-empty.
foreach($item in $obj.specialTags) {
  if ($item."!hidedue" -ne "") {
     $do_fix = 'true'
  }
}
# 4. If the tag '!hidedue' found do the following:
if ($do_fix -eq 'true') {
    # A. remove due tag
	$obj.specialTags | Where {$_.due} | ForEach{$_.due = ''}
    # B. remove `!hidedue` tag as well
	$obj.specialTags | Where {$_."!hidedue"} | ForEach{$_."!hidedue" = ''}
    # C. set tag `spent` value to zero
	$obj.specialTags | Where {$_.spent} | ForEach{$_.spent = '0'}
    # D. add a new tag `status` with value `fixed`
	[hashtable]$objectProperty = @{}
	$objectProperty.Add('status', 'fixed')
	$object = New-Object -TypeName psobject -Property $objectProperty
	$obj.specialTags += $object
}
# 5. Write the resulting JSON to the STDOUT pipe, so TTDL picks up the changes
Write-Output (ConvertTo-Json $obj)

Now TTDL opens the script and writes JSON into scripts STDIN:

{"description": "fix bug due:2023-06-15 spent:40 !hidedue:abc",
    "optional": [ {"done": "  " }, {"pri": "  "} ],
    "specialTags": [ {"due": "2023-06-15"}, {"spent": 40}, {"!hidedue": "abc"} ]}

After the plugin processes the input it prints out to STDOUT the resulting JSON:

{"description": "fix bug due:2023-06-15 spent:40 !hidedue:abc",
    "optional": [ {"done": "  " }, {"pri": "  "} ],
    "specialTags": [ {"due": ""}, {"spent": 0}, {"!hidedue": ""}, {"status": "fixed"} ]}

TTDL picks up the result, updates the subject and columns and prints the following:

# D P Created    Finished   Due        Subject
-----------------------------------------------
1                                      fix bug spent:0 status:fixed
-----------------------------------------------
1 todos (of 1 total)

Extra features

Each command that modifies todo list supports dry run mode. The mode is enabled with an option --dry-run. When executing ttdl with the option, it finds out which todos would be changed after the command completes, then displays existing todos and their new values.

By default TTDL outputs the todo list in long mode and uses colors. To disable colors, use an option --no-colors. To make the output shorter, use an option --short to show only a few the most important fields(ID, completion mark, priority, and subject), or choose which fields to display with an option --fields: a comma-separated list of fields. NOTE: the option --fields defines only a field visibility, but not its order. So, --fields=pri,due and --fields=due,pri result in the same output. A list of available field(column) names:

id - task's ID column
done - column with x marks for done tasks
pri - priority column
created - column with task creation date
finished - column with task finish date
due - column with due date
thr - column with threshold date
spent - column with total time spent on the task
uid - column to display user-defined tag id value (e.g, for task do not forget to register online with id:ABD-245, TTDL displays ABD-245 in UID column)
parent - task parent's ID column
prj - columns with task projects (comma-separated list)
ctx - columns with task contexts (comma-separated list)

For easier reading due date, there is an option --human that turns dates into relative dates. So, due date 2018-11-11 can turn into in 3d (if the current date is 2018-11-08) or into 3d overdue(if the current date is 2018-11-14). Using an option --compact makes the output even shorter: it removes all ins and overdues. To understand whether a todo is overdue or not, just check its color: overdue ones are drawn in red color(unless you used the option --no-colors or modified color in TTDL config). Option --human supports a list of fields to show as relative ones: ttdl l --human="due".

Syntax highlight

For better readability you can enable syntax highlighting when printing todo's subject. The highlighting is disabled by default. To enable it, either pass --syntax option in the command line or turn it on in TTDL configuration file (see example in provided ttdl.toml, section [syntax]). Also you can disable temporary syntax highlighting if it is enabled in the configuration by passing the command-line option -no-syntax.

Besides turning highlighting on and off, the configuration allows tuning the keyword colors. Default colors for keywords are:

tag color is bright cyan
hashtag color is cyan
project color is bright green
context color is green

Hide duplicated info

TTDL prints the task's subject as-is. It can result in duplicated information. E.g, by default Due column shows task's due date. At the same time, the due date is also displayed in the column Subject in a form due:2000-01-01. You can override this application behavior by either passing command-line option --clean-subject or modifying the configuration file - change the option global.clean_subject. Possible values:

none, no or nothing - the default mode: subjects are printed as-is
tags - hide only tags from the output, but keep duplicated prj and ctx entities even if you enabled columns for them
all or yes - filter out all duplicated stuff from subjects

The example of how the option affects the output

Let's assume, we have the following todo.txt file:

+food @drink buy milk at shop due:2023-05-08

Now, let's try various combinations of fields and clean-subject option. The output is minimized to show only affected lines:

# Default output with 'clean-subject=no`
$ ttdl --fields=pri,due,prj,ctx
. P Due        Project  Context Subject
-----------------------------------------
1   2023-05-08 food    drink   +food @drink buy milk at shop due:2023-05-08

# Hide only duplicated tags: 'due' entity is gone from 'Subject'
$ ttdl --fields=pri,due,prj,ctx --clean-subject=tags
# P Due        Project Context Subject
----------------------------------------
1   2023-05-08 food    drink   +food @drink buy milk at shop

# Hide all duplicated stuff: due, project, and context are gone
$ ttdl --fields=pri,due,prj,ctx --clean-subject=all
# P Due        Project Context Subject
----------------------------------------
1   2023-05-08 food    drink   buy milk at shop

# Hide all duplicated stuff and disable 'Context' column. Now '@drink' remains in the subject
$ ttdl --fields=pri,due,prj --clean-subject=all
# P Due        Project Subject
 --------------------------------
1   2023-05-08 food    @drink buy milk at shop

Edit in keep-tags mode

The command edit supports an option --keep-tags or -k. The option is useful when you want to modify a todo but you do not want to type all its properties (project, due date, tags etc) again.

While the option can save a lot of time when making a small change, it has some drawbacks:

all existing properties (project, context, tags, and hashtags) are moved to the end of the subject
the order of properties is not stable. The old properties are added to the end of the new subject in the following order: projects, contexts, tags, and hashtags
a new subject can contain new properties. Most of them are kept as-is. Except basic ones that are overwritten with those of the original subject. The list of the properties that cannot be modified by defining them inside a new subject: done, priority, creation date, finish date, due date, threshold date. Though, due and threshold date can be set if they were missing in the original todo

Examples

Replace a subject and keep all the rest intact

$ ttdl edit 2 "buy cake" -k --dry-run
Todos to be changed:
 # D P Created Finished Due        Subject
-------------------------------------------
 2   A                  2023-08-21 buy milk due:2023-08-21
New todos:
 2   A                  2023-08-21 buy cake due:2023-08-21

Replace a subject and add new tags. Note that the new tag location remains at its original position, but existing due is moved to the end

$ ttdl edit 2 "buy cake location:shop" -k --dry-run
Todos to be changed:
 # D P Created Finished Due        Subject
-------------------------------------------
 2   A                  2023-08-21 buy milk due:2023-08-21
New todos:
 2   A                  2023-08-21 buy cake location:shop due:2023-08-21

Trying to set a new priority does not work

$ ttdl edit 2 "(A) buy cake location:shop" -k --dry-run
Todos to be changed:
 # D P Created Finished Due        Subject
-------------------------------------------
 2                      2023-08-21 buy milk due:2023-08-21
New todos:
 2                      2023-08-21 buy cake location:shop due:2023-08-21

Setting a new due date works if it was empty, and fails otherwise. Note that the new due goes first, so it is overwritten with the old one that is mentioned later it the subject. That is why the old due is still used

$ ttdl edit 2 "buy cake due:2024-01-01" -k --dry-run
Todos to be changed:
 # D P Created Finished Due        Subject
-------------------------------------------
 2                                 buy milk
New todos:
 2                      2024-01-01 buy cake due:2024-01-01

$ ttdl edit 3 "buy cake due:2024-02-01" -k --dry-run
Todos to be changed:
 # D P Created Finished Due        Subject
-------------------------------------------
 3                      2024-01-18 buy milk due:2024-01-18
New todos:
 3                      2024-01-18 buy cake due:2024-02-01 due:2024-01-18

Human-readable dates

In addition to human-readable output, TTDL supports setting due and threshold dates in human-readable format. Both ways work: setting them in a string with due: and t: and in subcommands --set-due and set-threshold. Because due and threshold dates cannot be set in the past, rules for setting and displaying dates differs. Please note, that human-readable dates are replaced with absolute dates when saving to todo file. In the beginning you can play with human-readable dates without worrying about damaging existing todos by adding --dry-run to commands. This way only displays the content but does modify anything.

The list of supported abbreviations (more can be added in the future if needed):

Abbreviation	Date
`today`	Today's date
`#`	`#` stands for a positive number - sets date to `#` day of the current or next month
`#-#`	`#-#` stands for a "month-day" - if this day of the current year is in the past it sets due date to the "next_year-month-day" and "current_year-month-day" otherwise
`tm`, `tmr`, `tomorrow`	Tomorrow's date
`#d`	`#` is a positive number: in `#` days
`#w`	`#` is a positive number: in `#` weeks
`#m`	`#` is a positive number: in `#` months
`#y`	`#` is a positive number: in `#` years
`mo`, `mon`, `monday`	nearest Monday in the future
`tu`, `tue`, `tuesday`	nearest Tuesday in the future
`we`, `wed`, `wednesday`	nearest Wednesday in the future
`th`, `thu`, `thursday`	nearest Thursday in the future
`fr`, `fri`, `friday`	nearest Friday in the future
`sa`, `sat`, `saturday`	nearest Saturday in the future
`su`, `sun`, `sunday`	nearest Sunday in the future

All day of week abbreviations never set today's date. So, if the current date is Monday, due:mon sets the due date to the next Monday.
#d, #w, #m, and #y are addictive and can be grouped. Moreover, you can use the same abbreviation as many times as you want. Examples: due:3d4d is the same as due:1w; and due:1w1d is the same as due:11d
#m and #y does not add a constant number of days to the current date. They increase the month and year respectively with one extra rule: if current date is the last day of the month, the new date is the end of the month as well. E.g., due:1m when current date is 2020-02-29 sets due date to 2020-03-31.
# and #-# never sets the date in the past. So, if # is less than the current day of month, the resulting date is in the next, otherwise it is in the current period(month for #, year for #-#). The same rule about the last day of month as in 3. is applied here: due:29 for current date 2020-02-29 sets due date to 2020-03-31.
# and #-# accept values for a day in a range [1..31], bigger numbers cause errors. If day number is greater than the number days in a month, the last day of the month is set. So, it is safe to use due:31 for any month to set due date to the last day of the month. Examples: due:31 for date 2020-02-05 sets the due date to 2020-02-29, and due:02-31 sets due date to 2020-02-29.

Custom columns

Tags are useful to keep extra information but even with syntax highlighting it may be hard to spot a certain tag inside a long subject. Custom columns allows you to display values of selected tags in a separate columns for better readability. In addition, it is possible to define rules to set the output color depending on a tag value.

Two steps to enable custom columns:

Define all custom columns in the configuration file: add an array of [[fields]] to the configuration. Optionally, add highlight rules for columns as an array [[fields.rules]].
New columns are hidden by default. To show them, pass --fields=field1,field2 in the command line.

Custom field quirks and limitations

Every column has 5 properties: name, title, kind, width, and highlight rules. All of them, except highlight rules are mandatory. The property width can be set to 0 - in this case its width is chosen by TTDL
At this moment, automatic width does not check all values of a tag to calculate its maximal width. It just sets the width depending on the column kind. So, except columns of date kind, the other column widths probably would be too wide or too short most of the time
TTDL does basic check for custom columns properties: the color must be valid; the kind must be one of str(its alias is string), int(its alias is integer), float, date, duration, and bytes; if width is not 0, the length of title must be equal to or less than width
If a value is too long, it is truncated to the column width - no word wrap for custom columns
Custom columns are always displayed after the built-in ones and the order is the same in which they are defined in the configuration file
Highlight rules provide two properties: range and color. The property range can be on of three types: empty string - it matches any value, list of values separated with a comma - a tag value must equal any of the list values, range - two values separated with ..(open ranges like ..5 or 5.. are allowed)
All rules are tested in the order of their declaration in the configuration file
Both ends of a range are inclusive. But because of the previous bullet point, you can simulate non-inclusive ends. E.g, defining 4.. rule before 0..4 makes the latter rule non-inclusive(i.e, it becomes equal to >=0 && < 4 because 4 always matches the former rule >= 4)
For columns of duration kind you can set human-readable duration and TTDL compares them correctly. Available suffixes: w - a week, d - a day, h - an hour, m - a minute, s - a second. As a rule, s can be omitted - a value without any suffixes is considered as a value in seconds. A tag value can include any number of intervals in any order, e.g, 89m1d5 is the same as 1d1h29m5s or one day and one hour and 29 minutes and 5 seconds
For columns of bytes kind you can standard suffixes. One letter ones: k, m, g, t, p, e. Two letter ones: kb, mb, gb, tb, pb , eb. Three letter ones: kib, mib, gib, tib, pib, eib. Note: at this moment all suffixes are multiple of 1024, so k = kb = kib = 1024 bytes. A value without suffixes is in bytes. In opposite to duration, this kind of values can have only one suffix. So, e.g., 1mb2kb is invalid value and it is treated as an empty value
Rules for date columns can include special dates: yesterday, today, tomorrow, soon(currently it is today + 7 days), last - the last day of the month, first - the first day of the month, day of week(friday - this upcoming Friday). It makes rules more flexible
While rules for date column support special dates, the tag value must be a date in format YYYY-MM-DD.

Custom column example

Let's assume, you manage a team that includes you(me), technical writer(Tina), two junior developers(Mike and Andy), and a few middle developers. A task can have an estimation time and contain a day when you should check how the task is going (it is not the same as due date).

For person responsible for a task you choose a tag who:(kind string), for estimation time - a tag est:(kind duration), and for check date - a tag chk:(kind date).

Now let's add colors to quickly read todos. You want to mark your tasks with red color, juniors' with bright blue color, documentation tasks are green color, the rest tasks has default color. Let's also separate tasks by estimated time:

green color for tiny tasks (less than or equal to 1 hour)
blue color for small tasks (between 1 hour and 4 hours)
red color for huge tasks (1 week or longer)

The last highlight is for check date. Overdue checks are red. Checks that should be done first(i.e, they are coming today or soon) are bright yellow.

Now open ttdl.toml and add the custom columns with rules to it:

[[fields]]
name = "who" # tag name
title = "Who" # Title of the column in the output
kind = "string" # type of the tag value. If you are not going to use `fields.rules`
                # for coloring, it is safe to set `string` kind for every column.
width = 8 # column width
[[fields.rules]]
range = "Tina"
color = "green"
[[fields.rules]]
range = "Andy,Mike" # either of juniors: Andy or Mike
color = "bright blue"
[[fields.rules]]
range = "me" # my tasks
color = "red"

[[fields]]
name = "est"
title = "Estimate"
kind = "duration"
width = 8
[[fields.rules]]
range = "..1h"  # shorter than or equal to 1 hour
color = "green"
[[fields.rules]]
range = "1h..4h" # >= 1 hour and <= 4 hours
color = "blue"
[[fields.rules]]
range = "1w.." # 1 week or longer
color = "red"

[[fields]]
name = "chk"
title = "Check"
width = 0
kind = "date"
[[fields.rules]]
range = "..yesterday" # overdue check
color = "red"
[[fields.rules]]
range = "today..soon" # between today and today+7 days, inclusive
color = "bright yellow"

Let's assume that today is 2022-12-31 and your todo.txt looks like this:

2022-10-10 update docs est:1w who:Tina chk:2023-01-09
2022-07-20 design mail server who:me est:1d4h
2022-07-25 fix crash in logger est:2h who:John
2022-10-10 upgrade dependencies who:Mike est:4h chk:2022-12-27
2022-10-11 write test for new API call who:Andy est:1h chk:2023-01-03

After that, if your the command ttdl --fields=who,est,chk, you'll see this output in the terminal window:

Command line examples

By default todos from a given range are processed only if they are incomplete. To process all(both done and incomplete), add an option --all or -a. To process only done todos, add an option -A. NOTE: the only exception is the command clean|archive, it enables option -A automatically if --all is not present in command line.
