buildout_script 0.3.1

Overview

buildout_script is a zc.buildout recipe for generating scripts from a template. Unlike scripts specified by the console_scripts entry point, those generated by buildout_script are not restricted to Python code.

Scripts are generated from templates and can include settings from the buildout substituted at runtime.

One example usage is the generation of a wrapper script for Paste Script to check the status of a daemonized server process (see paster-check below).

Usage

To use the buildout_script recipe, specify it as the recipe for a zc.buildout part along with the template part. For example:

[sample_part]
recipe = buildout_script
template = paster-check.sh.in

The script will be created in the bin-directory. You may also specify the following parameters:

target

The filename for the generated script; if omitted, the script will have the template filename without the extension.

template_dir

An optional directory to look for templates in. Default: templates Templates included with the recipe may also be used without specifying a template_dir.

Templates

Template variables should be formatted using the buildout convention of ${part-name:variable-name}.

NB. Until version 0.2a1 of buildout_script the python string formatting syntax was used where the dictionary for the formatting operation was a flattened dictionary of the buildout settings and part settings.

For example, a trivial script template to list the files in the buildout installation directory would look like this:

#!/bin/bash

# Sample buildout_script script template
ls ${buildout:directory}

buildout_script ships with one script template, paster-check.sh.in, described below. Additional template contributions are welcome.
