lolologist 0.5.0

A utility that automatically generates an image macro from your webcam whenever you commit to a git repository.

A python-based tool that automatically generates an image macro from your webcam whenever you commit to a git repository. Inspired by lolcommits.

Installing

Linux

BEFORE installing lolologist, make sure that the following packages are installed locally:

• python-dev

• libfreetype6-dev

• libjpeg-dev

• mplayer

If pillow is already installed and you do not have the packages above, you need to uninstall it and install those packages. This is because when pillow is installed, it compiles optional features based on the availability of those packages. You would do this with commands:

sudo pip uninstall pillow
sudo apt-get install python-dev libfreetype6-dev libjpeg-dev

# Optional, for a better font
sudo apt-get install ttf-mscorefonts-installer

To install lolologist, after confirming that the above prerequisites are installed, run sudo python setup.py install, or install via pip.

OS X

BEFORE installing lolologist, make sure that the following Homebrew packages (or their equivalents) are installed locally.

• freetype

• jpeg

• imagesnap

Also, allow the locate daemon to run. This is necessary for font detection.

sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.locate.plist

To install lolologist, after confirming that the above prerequisites are installed, run sudo python setup.py install, or install via pip.

Using

1. Within the root of your git repository, type lolologist register. This should add a githook that will trigger the program every time you commit.

2. Commit!

The path to your photo will be printed in the commit output. The path is configurable - see the Output* options in the configuration section below.

Fonts

Due to licensing concerns, I can’t distribute lolologist with the iconic Impact TrueType font. To account for this, lolologist will use your system’s Impact if it exists, or fall back to an open font.

If Impact isn’t installed on your system, download and install it, and then run either lolologist setfont or lolologist setfont <path-to-font> to load it.

Configuration

The utility can be configured through the .lolologistrc file, usually found in your home directory. If the file doesn’t exist, feel free to create it. The following fields are accepted:

Field	Description
Camera	The video device to use. (e.g. for Linux: /dev/video1, for OS X: iSight)
FontPath	The full path to the Impact font’s TTF file
Lolspeak	on if commit messages should be translated to lolspeak, off otherwise
OutputDirectory	The format string for the directory into which all images will be placed
OutputFilename	The format string for the name of the generated file
OutputFormat	The type of image to generate (e.g. jpg)
UploadImages	on if macros should be uploaded to the internet, off otherwise
UploadUrl	The URL to post the generated image macro to

Pythonic format strings are accepted for the outpute file name, with the caveat that percent signs have to be escaped with another percent sign.

For example, if you wanted to group images by the commit year and month, you could use the following:

OutputDirectory = ~/.lolologist/{project}/{time:%%Y}/{time:%%m}

Possible format parameters:

Parameter	Type	Description
project	string	The name of the git repository’s directory
revision	string	A ten character ref sha
message	string	The entire commit message.
time	datetime	The time of the commit.
