Log commands to a .history file for repos

README.md

A problem with repositories is sometimes you do not remember what commands you ran to bootstrap the application, or what generators were used. A history file similar to .bash_history would be handy for a per-project basis. The h command above provides a wrapper around this functionality. It should be portable across any system with bash.

Run a command and write out the command to the git project's .history file, this logs $@ to .history

$ h mix phx.new project_name
$ h mix deps.get
$ h mix ecto.create
$ cat .history
mix phx.new project_name
mix deps.get
mix ecto.create

Get the last command in the history file, useful for scripting

$ h
mix ecto.create

For example, to add a commit with a message of the last command with git commit -m "$(h)"

$ git add .history
$ git commit -m "$(h)"
[main 8a24723] ls -ahl
 1 file changed, 2 insertions(+)
$ git log -1

    mix ecto.create

h

h() {
    local history_file="$(git rev-parse --show-toplevel)/.history"
    case $1 in
    "")
        tail -1 $history_file
    ;;
    *)
        echo $@ >> $history_file
        $@
    ;;
    esac
}

Also worth noting another good trick if this was the last command you entered in bash. git commit -m "$(echo !!)"
