What is Giturl?

It's a tool that allows you to pack Git repository data into single URL. For example:

% giturl https://github.com/zdharma/giturl -r devel -p lib/coding_functions.cpp

Protocol: https
Site:     github.com
Repo:     zdharma/giturl
Revision: devel
File:     lib/coding_functions.cpp

gitu://ŬṽǚǫoŒẗ6ẏȅcЭÑẩőn4ầŘїệαЃȣϟṈӛŀї

% giturl -d gitu://ŬṽǚǫoŒẗ6ẏȅcЭÑẩőn4ầŘїệαЃȣϟṈӛŀї
Protocol: https
Site:     github.com
Repo:     zdharma/giturl
Revision: devel
File:     lib/coding_functions.cpp

This is Zsh implementation. You don't have to use Zsh as your shell, just have it installed, like Ruby. There is C++11 implementation too.

The resulting URL is highly compressed thanks to use of Huffman codes and base-1024 encoding. Compare length of the above data to the gcode in URL:

It is 29 vs 62 characters, and you would normally need additional description like "the branch is: ", etc. Giturl allows to easily grab repository data from web page and terminal.

Limitations

Only following characters can appear in input data – in the server, repository path, revision, etc.: [a-zA-Z0-9._~:-]

Characters used in base-1024 encoding

The characters are carefully chosen so that double clicking GitURL selects the whole gcode. Asian scripts are not used because characters from them are double-width and they would consume the space saved by the compressions.
