Timewarrior Project
===================
Timewarrior is a program that records tagged time blocks that represent tracked
time. This data is then used to create reports that show how that time was spent.
To make this task easier, and more useful, Timewarrior can access holidays, a
pre-defined working schedule, and support flexible time/date specifications,
implement a simple stop-watch tracking feature, generate custom reports, and
apply a set of rules to impose constraints and check the data.
Using a hook scripts, Timewarrior can be used as a backend time-tracking
feature for Taskwarrior, any other program, or simply as a standalone utility.
Timewarrior aims to be the tool of choice if you need to track time and generate
timesheets.
Goals
-----
- Provide a personal tool to easily track and report time spent, with low
friction.
- Support all workflows.
- Provide an extension-friendly tool.
- Support policies via the rules system.
- Integrate with Taskwarrior, Tasksh.
- Store data in plain UTF-8 text.
Non-Goals
---------
- Completely independent from Taskwarrior, Taskserver, Tasksh.
- Time tracking is about recording the past, not planning the future.
- No cloud support, no sync support, all data is local. Tracked time is
sensitive personal data and will not be transmitted.
- No explicit multi-user support, although using tags to track individuals is
possible.
- There is no hook system as Timewarrior is a data sink, not a data source.
That said, there will be rules that can act as hooks, but will be more
flexible.
- No features without a compelling use case.
Tags
----
Tags represent tracking categories. Tags are arbitrary UTF8 strings. A tag may
be a single unquoted word, or a quoted string if it includes spaces.
A tag may be used without being defined, but if a tag is defined, then it may
have associated metadata, such as a start date representing the first date on
which it may be used, and an end date, when it expires. A tag may have a budget,
which is the maximum trackable time for a period.
An interval may have multiple tags associated with it, but the tags apply to the
whole interval only. In this example, there are overlapping tags:
$ timew start tag1
...
$ timew start tag2
...
$ timew stop tag1
...
$ timew stop
By default, when the interval for 'tag2' starts, the interval for 'tag1' is
automatically stopped, because tags do not overlap. This then makes the next
command ('timew stop tag1') yield an error, because 'tag1' was not active. If
however, both 'tag1' and 'tag2' are defined with the 'overlap' metadata, then
there will not be an automatic stop for 'tag1'.
Hints
-----
There are built-in hints, that influence processing. For example, ':debug' puts
the program in debug mode, and ':fill' indicates to a 'track' command that you
wish to fill in the available time. Another hint, ':week' means that a command
should only affect the last week.
There are user-defined hints, that can act as macrosaliases, for example the
':staff' hint could mean a 'Staff Meeting' and 'Admin' tag set.
Commands
--------
The command set will include:
config Modify configuration
track Record tracked time
report Run a report
undo Undo a change
tags Show all tags
gaps Show untracked gaps in the schedule
import Import JSON data
export Export JSON data
help Show help text
x Run extension 'x'
There will be built-in commands, and an extensions mechanism that allows reports
to be added as extensions, while being handled as though they were built-ins.
Undo
----
All commands that change configuration or data need to be recorded as-is in the
undo.data file, so that an 'undo' command can later rewind the changes properly.
All undo will happen at the command level, not the delta level. That means if
one command results in three changes, a single 'undo' command will revert the
three changes associated with the one command.
Extensions
----------
A simple extension mechanism allows custom reports to be written and shared.
Most reports will be external scripts that use the extension API.
DOM Access
----------
Timewarrior will support a DOM, allowing rules and extensions to access internal
data.
[TBD]
--- Raw Notes ---
- Need syntax to adjust any recorded data.
- It should be forgiving when you forgot to stop a task. Maybe a specific
command, instead of "stop" use "forgot" or directly "edit". Then I would
like to express either "stopped 30min ago" or "it lasted only 1hour”.
