HACKERS_README

@ -3,21 +3,12 @@ cat << eof
Hey hackers,
this README is for you, for those who want to dig into cdist, hack it or try
to get a deeper understanding.
A lot of documentation is still missing, but running cdist-quickstart should
give you an impression of how cdist works.
to get a deeper understanding. Please read doc/man/cdist-hacker.text.
I hope you have a lot of fun with cdist, because it was also a lot of fun to
develop it!
-- Nico, 20110304
## Conventions
- All variables exported by cdist are prefixed with a double underscore (__)
- All cdist-internal variables are prefixed with __cdist_ and are generally not exported.

cdist-type__key_value(7)
========================
Steven Armstrong <steven-cdist--@--armstrong.cc>
NAME
----
cdist-type__key_value - Change property values in files
DESCRIPTION
-----------
This cdist type allows you to change values in a key value based config
file.
REQUIRED PARAMETERS
-------------------
value::
The value for the key. Setting the value to __NOTSET__ will remove the key
from the file.
file::
The file to operate on.
delimiter::
The delimiter which seperates the key from the value.
OPTIONAL PARAMETERS
-------------------
key::
The key to change. Defaults to object_id.
EXAMPLES
--------
--------------------------------------------------------------------------------
# Set the maximum system user id
__key_value SYS_UID_MAX --file /etc/login.defs --value 666 --delimiter ' '
# Same with fancy id
__key_value my-fancy-id --file /etc/login.defs --key SYS_UID_MAX --value 666 \
--delimiter ' '
# Enable packet forwarding
__key_value net.ipv4.ip_forward --file /etc/sysctl.conf --value 1 \
--delimiter '='

Document redefine behaviour
release cdist 1.4.0
perhaps include __self
Core:
- support $__self = relative_type/object_id
- cache
Cache:
Assume you want to configure stuff one host ("monitor node"),
depending on the configuration of other hosts ("cluster nodes").
For instance, the monitor host would like to know,
which hosts are configured with the provider
"apache" and option --start true.
This requires the monitor node to be able to
query all other configured nodes. It can't
ask for all hosts, because cdist does not
know which hosts are configured or may exist.
Example implementation
If cdist keeps ("caches") the configuration of every
node it configures, each new node can query the
cache for existing nodes that acquired the given
configuration.

Nico Schottelius <nico-cdist--@--schottelius.org>
NAME
----
cdist-hacker - How to get (stuff) into cdist
WELCOME
-------
Welcome dear hacker! I invite you to a tour of pointers to
get into the usable configuration mangament system, cdist.
The first thing to know is probably that cdist is brought to
you by people who care about how code looks like and who think
twice before merging or implementing a feature: Less features
with good usability are far better than the opposite.
UNDERSTANDING CDIST INTERNALS
-----------------------------
IF you are interested in how cdist internally works, you can open
bin/cdist-config and bin/cdist-deploy-to in your favorite editor and
read the scripts bin/cdist-deploy-to calls. The magnificent HACKERS_README
may be of great help as well.
CODING CONVENTIONS (CORE)
-------------------------
- All variables exported by cdist are prefixed with a double underscore (__)
- All cdist-internal variables are prefixed with __cdist_ and are generally not exported.
HOW TO SUBMIT STUFF FOR INCLUSION INTO UPSTREAM CDIST
-----------------------------------------------------
If you did some cool changes to cdist, which you value as a benefit for
everybody using cdist, you're welcome to propose inclusion into upstream.
There are though some requirements to ensure your changes don't break others
work nor kill the authors brain:
- Code submission must be done via git
- Code to be included should be branched of the upstream "master" branch
- Exception: Bugfixes to a version branch
- Code submissions must be in your master branch
- Exception: If you only want a comment on your code, but not an inclusion.
- Do not add conf/manifest/init - This file should only be touched in your
private branch!
As soon as your work meets these requirements, you can contact me
(IRC, Mailinglist, Phone, RFC 1149) and I'll check your code before
including it.
HOW TO SUBMIT A NEW TYPE
------------------------
Submitting a type works as described above, with the additional requirement
that a corresponding manpage named man.text in asciidoc format with
the manpage-name "cdist-type__NAME" is included in the type directory
AND asciidoc is able to compile it.
