Commit hooks to prepend jira tags to commits (using the name of the current branch)

commit-msg

#!/usr/bin/env ruby
# Avoid commiting when the commit message contains ONLY the JIRA tag

# Get the name of the current branch
current_branch = `git symbolic-ref --short HEAD`

# Check if we are on a JIRA branch
TAG_REGEX = /^([[:alpha:]]+)[-_](\d+)$/
if current_branch =~ TAG_REGEX
  file_name = ARGV[0]
  jira_tag = "[#{$1.upcase}-#{$2}]"
  
  File.open(file_name, 'r') do |f|
    # Get First line
    first_line = f.readline
    
    # remove the tag
    first_line[jira_tag] = ''
    
    # And check the length
    if first_line.strip.length == 0
      $stderr.puts "Please provide a non-empty log message (JIRA tag only is not enough !)"
      $stderr.puts "ABORTING"
      exit 1
    end
  end
  
end
