Script to list annotated tags on the CLI with git in a nicely formatted manner

git-lt

#!/bin/bash

# Get all the annotated tag references
refs=$(git for-each-ref --format="%(if:equals=tag)%(objecttype)%(then)%(refname:short)%(end)" refs/tags)

# Review those to find the longest reference name
refs_as_list=(${refs})
let longest_ref=0
for i in "${refs_as_list[@]}"
do
    if (( ${#i} > longest_ref ))
    then
        let longest_ref=${#i}
    fi
done

# Now build the format string
fmt="%(color:yellow)%(align:${longest_ref})%(refname:short)%(end)%(color:reset) - %(color:red)%(*objectname:short)%(color:reset) - %(contents:subject) %(color:green)(%(taggerdate:relative)) %(color:bold blue)<%(taggername)>%(color:reset)"

# And finally spit out the nicely formatted and padded list
git tag --list --sort=-taggerdate --format="$fmt" $@ ${refs}
