mash

A simple make-ish task runner in bash to avoid makefiles. Nothing fancy.

---

Define functions in bash with the name run:x and then execute with ./mash x

run:task:name () {
  echo "I am task:name"
}
run:other(){
  printf "I'm %s\n" "$*"
}

$ ./mash task:name  #runs `run:task:name`
I am task:name

$ ./mash other a bunch of things  #runs `run:other`
I'm a bunch of things

Setup

The mash scripts header and footer can be printed with the dump task to initialize a new file

$ ~/repos/make.sh/mash dump > ~/myrepo/mash
$ chmod 755 my/mash

Or all in one

./mash dump:to ~/myrepo/mash

Tasks

List tasks

$ ./mash

or

$ ./mash help
Commands:
  task:name
  other

The default dump task includes a shell completion helper

$ ./mash completion:words
task:name
other

For zsh completions add a _mash file in $fpath

#compdef mash

local context state state_descr line
tasks=( $(_call_program completion:words $words[1] completion:words) )
_arguments "1:task:($tasks)" \
           "*:arg:->args"

bash completion /etc/bash_completion.d/mash

_mash()
{
  #pwd
  #echo "0:$0 1:$1"
  _script_commands=$($1 completion:words)

  local cur
  COMPREPLY=()
  cur="${COMP_WORDS[COMP_CWORD]}"
  COMPREPLY=( $(compgen -W "${_script_commands}" -- ${cur}) )

  return 0
}
# no space after
#complete -o nospace -F _mash ./mash.sh
complete -F _mash mash

sh or bash

POSIX sh doesn't guarentee a function named with a : works, even though it does work for most implementations. bash also allows for much simpler ${var:1:2} substring indexing.
