@hackage file-command-qq0.1.0.2

file-command-qq is a simple quasiquoter for running system commands that take a filepath as an argument.

For instance

>>>>>>>>>>>>

will return

thing.txt
ExitSuccess

You can think of [s|echo $filename|] essentially converts into

\path -> system $ "echo" ++ encodeString (filename path)

Here is another example

>>>

All "file parts" start with a '$'. The '$' can be escaped by preceding it with a '\'

There are the following options for "file parts"

• $path

• $root

• $directory

• $parent

• $filename

• $dirname

• $basename

• $ext

Which correspond to the respective functions in https://hackage.haskell.org/package/system-filepath-0.4.6/docs/Filesystem-Path.html#g:1
