As of version 0.20, all of the parts of the commit message flashbake generates come from plugins.
As of version 0.22, the names of the stock plugins changed. This reflects the shift to implementing them as classes rather than modules.

There are many stock plugins:

  • flashbake.plugins.timezone:TimeZone
  • flashbake.plugins.weather:Weather
  • flashbake.plugins.uptime:UpTime
  • flashbake.plugins.feed:Feed
  • flashbake.plugins.growl:Growl
  • flashbake.plugins.microblog:Twitter
  • flashbake.plugins.microblog:Identica
  • flashbake.plugins.music:Banshee
  • flashbake.plugins.music:iTunes
  • flashbake.plugins.location:Location
  • flashbake.plugins.scrivener:ScrivenerFile
  • flashbake.plugins.scrivener:ScrivenerWordcountFile
  • flashbake.plugins.scrivener:ScrivenerWordcountMessage

These are enabled by adding the a “plugins:” line or lines to your .flashbake file.

Your plugins: entries might look like this:

plugins:flashbake.plugins.timezone:TimeZone,flashbake.plugins.weather:Weather
plugins:flashbake.plugins.feed:Feed

flashbake will combine multiple “plugins:” lines to create the total list of plugins to use.

Implementing Plugins

Plugins must be implemented in Python. If you create a ~/.flashbake/plugins/ directory, flashbake will add that to its Python path so any modules and classes there can be loaded. There is also a -p PLUGIN_DIR, —plugins=PLUGIN_DIR option if you want to specify some additional location. You do not need either the plugins directory in your home directory or the plugins option for the stock plugins to work, those are made available to Python and flashbake by following the proper installation. Also, if you are familiar with Python, you can make your modules available on its lookup path through any number of other means.

Plugins should extend the class flashbake.plugins.AbstractMessagePlugin. If a plugin uses the network, it should implementing an init that takes a plugin_spec string and call the super init passing in that string along with a True argument to indicate the plugin is connectable. See Feed and Weather for examples.

A plugin may implement an init method that takes a ControlConfig argument. In the init(self, config) method, the plugin may call the parent’s requireproperty and optionalproperty methods. These methods take a name argument, the name of an option in the control file that should be set as a property on the plugin itself. optionalproperty also takes an optional argument, a type, to which the option value string will be coerced. See Feed for examples of both of these methods being used.

There is also a shareproperty method from the flashbake.ControlConfig class that sets the option as a property on the config instance and on the plugin. See Weather for an example.

flashbake.plugins.timezone:TimeZone

This plugin just adds the configured time zone on your computer to the commit message. It tries a few things to determine the timezone.

As of 0.22, the search for a TZ setting has been changed.

  1. It will look for a line, “timezone:” in the project’s flashbake file or the user’s .flashbake/config file and use that if present.
  2. It looks for an environment variable, TZ, which many Linux distros set.
  3. If that is not set, it will look for a file, “/etc/timezone”, and try to read it. Other Linux distros will create and write this file.
  4. If that fails, it will look for a symbolic link, “/etc/localtime”, and parse the name of the file to which it points. This is common on Macs.

If all of these fail, then it will write a line to that effect in the commit message.

flashbake.plugins.weather:Weather

As of 0.22, this plugin will first use a “weather_city:” option if in the user’s config or the project’s config.

If there is no “weather_city:” this plugin uses the same logic as the timezone plugin to get a timezone value. It then parses that as the most common timezone names follow the form of “Continent/City_name”. It will parse out the city and fix it to drop out the underscore, if there is one. It then calls an undocumented Google API to get weather data as an XML file which it parses to construct a nice, readable line for the commit message.

flashbake.plugins.uptime:Uptime

This plugin read the file, “/proc/uptime”, and parses its contents to generate a human readable amount of time that your computer has been up and running. This plugin will only work on Linux.

flashbake.plugins.feed:Feed

This plugin requires some addition lines in your .flashbake configuration file.

As of 0.22 these have been renamed.

  • feed_url: – where is the URL to a feed that you want the plugin to read. It can be any feed, but most likely you’ll want to use the one for your blog. As of 0.22, both RSS and Atom feeds should work.
  • feed_author:<author’s name> – (optional as of 0.22) where <author’s name> is the name of the author in the feed, exactly as it appears in the feed. The plugin will only output feed items that match this author value.
  • feed_limit: – (optional as of 0.22) where is the maximum number of items to pull from the feed, default is 5 if unset.

As of 0.22, if you use the feed plugin, feed_url must be specified.

flashbake.plugins.microblog:Twitter (as of 0.23)

The Twitter plugin pulls items from a single user’s public Twitter feed. It requires some addition lines in your .flashbake configuration file:

  • twitter_user: – where is the Twitter user’s ID as seen in @replies
  • twitter_limit: – (optional) where is the maximum number of items to pull from the feed, default is 5 if unset.

flashbake.plugins.microblog:Identica (as of 0.23)

The Identica plugin pulls items from a single user’s public Identi.ca feed. It requires some addition lines in your .flashbake configuration file:

  • identica_user: – where is the Identi.ca user’s ID as seen in @replies
  • identica_limit: – (optional) where is the maximum number of items to pull from the feed, default is 5 if unset.

flashbake.plugins.music:Banshee (as of 0.23)

This plugin fetches the most recent tracks played by the Banshee music player and writes out the track’s title, artist and last time played. It supports some optional properties in your .flashbake configuration file:

  • banshee_db: – by default the plugin looks for ~/.config/banshee-1/banshee.db but if you know your database file is somewhere else, this lets you specify it
  • banshee_limit: – by default, the plugin pulls the last three tracks played (this doesn’t include the currently playing track), you can configure it to pull more
  • banshee_last_played_format: – if ommitted, the last played time is output per the C locale, if specified use format symbols similar the the unix date command (%H for hour, %M for minute, etc.)

flashbake.plugins.location:Location (as of 0.25)

This plugin doesn’t require any additional options but it does require a network connection. Accuracy of the plugin is limited by the free database it uses to convert your network address into a location.

flashbake.plugins.scrivener:Scrivener(File,WordcountFile,WordcountMessage)

Scrivener Preferences

Before activating the plugin you’ll want to open Scrivener. Under
Preferences → General ensure “Enable Subversion/CVS-compatible saving
(slower)” is checked.

If you are just activating this setting, you may wish to force a save of
your Scrivener project (Cmd-S).

Flashbake Configuration

Adding the plugin(s)

Add the following to your “plugins:” entry in your .flashbake (or
~/.flashbake/config) file:

flashbake.plugins.scrivener:ScrivenerFile,flashbake.plugins.scrivener:ScrivenerWordcountFile,flashbake.plugins.scrivener:ScrivenerWordcountMessage

The order is important.

(NOTE: the ScrivenerWordcount* plugins require ‘textutil’ to be
available which should be standard on Mac OS X 10.4+.)

Adding your Document

Add either “*.scriv” or “MyDocument.scriv” (where “MyDocument” is the
name of your scrivener document) to your .flashbake file.

Test

You may wish to test that the plugin is working by running:

$ flashbake —dryrun —context /path/to/project

You should see something similar to this in the output:

Wordcount: MyDocument.scriv
– Content 60165
– Synopsis 285
– Notes 2327
– All 62775

flashbake.plugins.music:iTunes (as of 0.26)

There is no configuration for this plugin. If iTunes is open and playing a track, the plugin will add a line with that info to the commit message. Otherwise, it will indicate that iTunes is not open.

flashbake.plugins.growl:Growl (as of 0.26)

Configuration of this plugin is optional. If totally omitted, then the user must be logged in and have Growl running. You must install the growlnotify program to use this plugin, the program is included in the Extras folder in the Growl .dmg file. The optional config properties are:

  • growl_host: specify a remote host to send Growl notices
  • growl_port: specify the port of a remote host running Growl
  • growl_password: it is recommended that you use a password when enabling remote notices with Growl, use this property to supply that password for a remote host
  • growl_growlnotify: specify the path to the growlnotify program
  • growl_title_prefix: specify a prefix to the title field in the Growl notices, defaults to “fb”
Something went wrong with that request. Please try again.
