vcs_commit

# save as ~/.zsh/function/vcs_commit
#
# In your ~/.zshrc
#
# fpath=(~/.zsh/function $fpath)
# autoload vcs_commit

# bindkey '\ec' vcs_commit
#
# Loads the widget and also binds it to Alt+c
#
# Use:
#   Assuming you are in a git repository of a bitbucket / jira branch using the atlassian jira git flow conventions
#   example "feature/EXP-1337-cool-new-feature
#
#   > Alt+x
#     will open the widget prompt
#   execute: _
#   > Type: commit ENTER
#   > git commit -m 'EXP-1337: '
#     resting the cursor just before the last quote
