Timetree is an interactive program to keep track of time spent on tasks and
subtasks and subsubtasks and so up, up to MAX_TREE_DEPTH defined in
timetree.h.
The program is entirely self contained and only needs make and a C compiler:
$ cd timetree
$ make
The program takes one command-line argument, which is taken as the name of the log file:
$ ./timetree log.txt
Following this command, the interactive session is started. Two commands are
used: [ to open a task, and ] to close it. The ] command takes an
optional string argument, to give the task a name. A newline terminates the
command line, which is thereupon appended to the log file together with a
timestamp. When the last open bracket is closed, the program will print out a
session summary.
In the following timetree session, the indentation is supplied by the program, while the user typed all the visible characters:
[
[t1
]
[t2
[t2.1
]
]
[t3
]
]
When the last closing bracket is typed, the program will print a session summary showing the individual task durations:
2025-07-11 17:02:49
=======================
00:00:02 (empty)
00:00:00 ├── t1
00:00:01 ├── t2
00:00:01 │ └── t2.1
00:00:01 └── t3
The log file will contain the timestamps and the typed info:
1752278569 [
1752278570 [t1
1752278570 ]
1752278571 [t2
1752278574 [t2.1
1752278575 ]
1752278575 ]
1752278577 [t3
1752278578 ]
1752278579 ]
If only a closing bracket is typed in the entire session, then timetree will print all sessions, and an overall summary at the end.
