commit-msg

#!/bin/bash

# original message
base=$(cat $1)
# ticket patterns
patterns=(ticket- issue- bug-)
# current branch name excluding namespace
current_branch=$(git symbolic-ref --short HEAD | cut -d/ -f2-)
# capitalize message's first char
message=`echo ${base:0:1} | tr '[a-z]' '[A-Z]'`${base:1}
# retrieve ticket number from patterns
i=0;
while [ $i -le 2 ]; do
  pattern=${patterns[$i]}
  if [ "${current_branch#$pattern}" != "$current_branch" ]; then
    ticket=${current_branch#$pattern}
  fi
  ((i++))
done
# prepend number to commit message
if [ -n "$ticket" ]; then
  echo "#$ticket $message" > $1
else
  echo "$message" > $1
fi
