Mashup your bash-fu with coffeescript-fu in the console with coffeepipe
npm install coffeescript coffeepipe-bash -g
How to use
Just fire up a terminal and start hacking away. This turns coffeescript into a nifty awk/swish armyknife-ish tool.
Examples
Simple eval
$ cfp 'new Date().toString()'
search / replace
$ echo "foo" | cfp '(s) -> s.replace /foo/, "bar"'
process line by line
$ echo -e "foo\nbar" | cfp '(s) -> ( "output: #{line}" for line in s.split "\n")'
filter by coffeescript file
$ echo -e "foo\nbar" | cfp ./filter.coffee
automatically convert array to lines
$ echo "one,two,three" | cfp '(s) -> s.split ","'
detect json / indent json
$ echo "[1,2,3,4]" | cfp '(s) -> JSON.stringify(s,null,2)'
cherrypick from JSON
$ curl -s https://api.github.com/users/coderofsalvation/repos | cfp 'input[0].name'
print x items from JSON
$ curl -s https://api.github.com/users/coderofsalvation/repos | cfp '(s) -> ( input.data[i].name for i in [0..4] )'
transform json
$ curl -s https://api.github.com/users/coderofsalvation/repos | ./cli.coffee '(s) -> input.data = input.data.slice(0,4) ; return input'
