templating engine for evaluating shell commands embedded in arbitrary templates
esh (embedded shell) is a templating engine for evaluating shell commands embedded in arbitrary templates. It’s like ERB (Embedded RuBy) for shell, intended to be used for templating configuration files. Unlike ERB it provides support for including one ESH template into another (since version 0.2.0).
The template processing consists of two phases: conversion to a shell script and evaluation of that script. You can even run just the conversion phase: esh -d will dump a shell script that you can execute directly by a shell (even on a system without esh installed). However, in that case, you will not get error messages source-mapped to point to the locations in the template file.
