shqq

Embed shell commands with interpolated Haskell variables, and capture output.

This library provides a quasiquoter for executing shell commands, somewhat similar to Perl's backtick operator. Shell commands are IO actions, and they capture the command's standard output as a String result.

You can use Haskell variables in a shell command. A string representation of the contents will be interpolated. The shell will see each interpolated variable as a single token without interpreting special characters, unless you choose otherwise.

Note: The shell escaping is not correct for the Windows shell. This library should fail to build on Windows, as well.

Examples of using this library are included in examples/.
