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'
