Grenade Coding Guide
|
|
====================
|
|
|
|
General
|
|
-------
|
|
|
|
Grenade is written in POSIX shell script. It specifies BASH and is
|
|
compatible with Bash 3.
|
|
|
|
Grenade's official repository is located at
|
|
https://opendev.org/openstack/grenade.
|
|
|
|
|
|
Scripts
|
|
-------
|
|
|
|
Grenade scripts should generally begin by calling ``env(1)`` in the shebang line::
|
|
|
|
#!/usr/bin/env bash
|
|
|
|
The script needs to know the location of the Grenade install directory.
|
|
``GRENADE_DIR`` should always point there, even if the script itself is located in
|
|
a subdirectory::
|
|
|
|
# Keep track of the current grenade directory.
|
|
GRENADE_DIR=$(cd $(dirname "$0") && pwd)
|
|
|
|
Many scripts will utilize shared functions from the ``functions`` file. This
|
|
file is copied directly from DevStack trunk periodically. There is also an
|
|
rc file (``grenaderc``) that is sourced to set the default configuration of
|
|
the user environment::
|
|
|
|
# Keep track of the current grenade directory.
|
|
GRENADE_DIR=$(cd $(dirname "$0") && pwd)
|
|
|
|
# Import common functions
|
|
source $GRENADE_DIR/functions
|
|
|
|
# Import configuration
|
|
source $GRENADE_DIR/grenaderc
|
|
|
|
|
|
Documentation
|
|
-------------
|
|
|
|
The GitHub repo includes a gh-pages branch that contains the web documentation
|
|
for Grenade. This is the primary Grenade documentation along with the
|
|
Grenade scripts themselves.
|
|
|
|
All of the scripts are processed with shocco_ to render them with the comments
|
|
as text describing the script below. For this reason we tend to be a little
|
|
verbose in the comments _ABOVE_ the code they pertain to. Shocco also supports
|
|
Markdown formatting in the comments; use it sparingly. Specifically, ``grenade.sh``
|
|
uses Markdown headers to divide the script into logical sections.
