NAME

|
|
cdist-language - Cdist Configuration language
|
|
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
A cdist configuration consists of the following parts:
|
|
|
|
- manifests (cdist-manifests(7))
|
|
- library (cdist-language-library(7))
|
|
- modules (cdist-language-modules(7))
|
|
|
|
In short the configuration is built as follows:
|
|
|
|
- conf/hosts/init is executed, the resulting output is used for module loading
|
|
- the appropriate modules are loaded and executed, which
|
|
- use library functions.
|
|
|
|
The three stages are used to seperate configurations:
|
|
|
|
- hosts contain mappings to created modules
|
|
- modules create (probably site specific) configurations using library collections
|
|
- the library is shipped with cdist, but can be extendet locally
|
|
|
|
|
|
- DSL: Shell!
|
|
- gives if, else and EVEN elsif for free!
|
|
- and case
|
|
- and and and
|
|
- and there's no os (solaris doesn't count) without a usable /bin/sh
|
|
- cdist defines what you can use
|
|
- you _can_ use os specific stuff
|
|
- but it's ugly and you shoot into your own foot
|
|
- "manifests" (use the same name here?) will be run/sourced
|
|
- inheritance possible via sourcing
|
|
- cdist-lib always preloaded
|
|
|
|
- document exported variables!
|
|
use __ prefix instead of __cdist (shorter writing, __ is defined as sytem anyway)
|
|
|
|
- library vs. modules?
|
|
|
|
Requirements:
|
|
It MUST be incredible easy/dumb to add new types.
|
|
=> growable default types
|
|
|
|
- how to write a module
|
|
- module function autoloading via *.sh
|
|
- module "manifest"?
|
|
- create functions in *.sh
|
|
- name functions "modulename_function"
|
|
module hellow
|
|
function kitty
|
|
=> hellow_kitty
|
|
|
|
- you are advised (not forced) to put files
|
|
to a subdirectory named "files"
