tracker - run App::TimeTracker


version 2.024


  ~/perl/Some-Project$ tracker start
  Started working on Some-Project at 09:03:41

  ~/perl/Some-Project$ tracker stop
  Worked 00:07:42 on Some-Project


tracker is the front end script to App::TimeTracker. tracker allows you to easily track and report the time you spend on various jobs, projects, tasks etc from the commandline.

Custom commands or adaptations to your workflow can be implemented via an "interesting" set of Moose-powered plugins. You can configure different sets of plugins for different jobs or projects.

Tip: Use tracker plugins to list all installed plugins. Read more about each plugin in App::TimeTracker::Command::PLUGIN-NAME.


App::TimeTracker is a Perl application, and thus requires a recent Perl (>= 5.10). It also reuses a lot of code from CPAN.


The easiest way to install the current stable version of App::TimeTracker is via CPAN. There are several different CPAN clients available:


The new and shiny CPAN client!

  ~$ cpanm App::TimeTracker
  --> Working on App::TimeTracker
  Fetching ... OK
  Configuring App-TimeTracker-2.009 ... OK
  Building and testing App-TimeTracker-2.009 ... OK
  Successfully installed App-TimeTracker-2.009
  1 distribution installed

If you don't have cpanminus installed yet, install it right now:

  ~$ curl -L | perl - --sudo App::cpanminus


CPANPLUS comes preinstalled with recent Perls (5.10 and newer).

  cpanp i App::TimeTracker is available on ancient Perls, and feels a bit ancient, too.

  cpan App::TimeTracker

From a tarball or git checkout

To install App::TimeTracker from a tarball or a git checkout, do the usual CPAN module install dance:

  ~/perl/App-TimeTracker$ perl Build.PL
  ~/perl/App-TimeTracker$ ./Build
  ~/perl/App-TimeTracker$ ./Build test
  ~/perl/App-TimeTracker$ ./Build install  # might require sudo


App::TimeTracker uses a bunch of config files in JSON format. The config files valid for a specific instance of tracker are collected by walking the directory tree up from the current working directory, and merging all .tracker.json files that are found, plus the main config file ~/.TimeTracker/tracker.json.

You can use this tree of config files to define general settings, per job settings and per project settings, while always reusing the configuration defined in the parent. I.e. the config settings sort of override the values defined further up in the tree.

Any time you call tracker, we look up from your current directory until we find the first .tracker.json file. This file marks the current project.

See App::TimeTracker::Command::Core and the various plugins for valid config parameters.

The different config files

Main config file: ~/.TimeTracker/tracker.json

The main config file lives in a directory named .TimeTracker located in your home directory (as defined by File::HomeDir). All other config files inherit from this file. You can, for example, use this file to define plugins you always want to use.

List of projects: ~/.TimeTracker/projects.json

This file lists all the projects App::TimeTracker knows of on this machine. The content is autogenerated, so please do not edit it by hand. We use this file to locate all your working directories for the various reporting commands.

Per project config file: your-project/.tracker.json

Besides being the last node in the tree of the currently valid configuration, this file also defines the containing directory as a project.


Given this directory structure:


If you hit start in ~/job/project/, all three of those config files will be merged and the resulting hash will be used as the current configuration.

If you hit start in ~/job/, only ~/job/.tracker.json and ~/.TimeTracker/tracker.json will be used.

This allows you to have global default settings, different default settings for different jobs, and fine tuned settings for each project. Of course you can have as many levels of configs as you want.

Tip: Use tracker show_config to dump the current configuration.

Using a different tree

Sometimes you do not want to arrange your projects in the hierarchical way expected by App::TimeTracker:


Both App-TimeTracker and App-TimeTracker-Gtk2TrayIcon live in the same directory and thus would be considered separate projects. But I want App-TimeTracker-Gtk2TrayIcon to be a sub-project of App-TimeTracker, without having to change the directory structure.

The solution: parent

In any config file you can define a key called parent. If this key is defined, the config-walker will use that project as the parent, and ignore the directory structure:

  ~/perl/App-TimeTracker-Gtk2TrayIcon$ cat .tracker.json

And here's the relevant output of tracker show_config:

  '_used_config_files' => [


Initial Setup

Call tracker init to set up a directory for time-tracking. tracker init will create a config file called .tracker.json in your current directory. Use this file to load plugins for this project and/or override and amend the configuration inherited from parent projects.

See Configuration for more information on how to configure tracker for your project(s).

Basic Usage

Call tracker start when you start working on a project, and tracker stop when you're done:

  ~/work/some_project$ tracker start
  Started working on some_project at 13:06:20

  ~/work/some_project$ hack .. hack .. hack

  ~/work/some_project$ tracker stop
  Worked 01:43:07 on some_project

To see how long you worked, use tracker report:

  ~/work/some_project$ tracker report --this day
  work                     02:15:49
     some_project             01:43:07
     another_project          00:32:42
  perl                     02:23:58
     App-TimeTracker          02:23:58
  total                    04:39:47

Advanced Usage with git, RT and IRC

By using some plugins we can make tracker a much more powerful tool. Let's use the git, RT and Post2IRC plugins for maximum laziness.

The first step is to add a setting to the tracker config file in your project directory. Or you could add those settings to a config file in a parent directory, see Configuration for more information about that.

  ~/revdev/Some-Project$ cat .tracker.json
    "plugins" : [
    "post2irc" : {
      "secret" : "bai0uKiw",
      "host" : ""
    "rt" : {
      "set_owner_to" : "domm",
      "timeout" : "5",
      "update_time_worked" : "1",
      "server" : "",
      "username" : "revbot"
      "password" : "12345",

After setting everything up, we can do a simple (but slightly amended) tracker start:

  ~/revdev/Some-Project$ tracker start --rt 1234
  Started working on SomeProject (RT1234) flux capacitor needs more jigawatts at 15:32
  Switched to a new branch 'RT1234_flux_capacitor_needs_more_jigawatts'

While this output might not seem very impressive, a lot of things have happened:

As soon as you're done, you do the usual tracker stop

  ~/revdev/Some-Project$ tracker stop
  Worked 00:15:42 on some_project

Which does the following:

Even if those steps only shave off a few minutes per ticket, those are still a few minutes you don't have to spend on doing boring, repetitive tasks (which one tends to forget / repress).

Tracking Files

Each time you start a new task, a so-called tracking file will be created. This file contains all information regarding the task you're currently working on (provided by App::TimeTracker::Data::Task, serialized to JSON via MooseX::Storage). If you call stop, the current time is stored into the tracking file and the time spent working on this task is calculated (and also stored).

All tracking files are plain text files containing JSON. It is very easy to synchronize them on different machines, using anything from rsync to version control systems. Or you can just use the SyncViaGit plugin!

Tracking files are stored in ~/.TimeTracker in a directory hierarchy consisting of the current year and the current month. This makes it easy (easier..) to find a specific tracking file in case you need to make some manual corrections (an interface for easier editing of tracking files is planned).

The filename of a tracking file looks like 'YYYYMMDD-HHMMSS_$project.trc', for example: 20110811-090437_App_TimeTracker.trc.
