NAME
----
cdist-reference - Variable, path and type reference for cdist


EXPLORERS
---------
The following global explores are available:

eof
(
   cd ../../conf/explorer
   for explorer in *; do
      echo "- $explorer"
   done
)

cat << eof 

PATHS
-----
If not specified otherwise, all paths are relative to the checkout directory.

conf/::
   Contains the (static) configuration like manifests, types and explorers.  

conf/manifest/init::
   This is the central entry point used by cdist-manifest-init(1).
   It is an executable (+x bit set) shell script that can use
   values from the explorers to decide which configuration to create
   for the specified target host.
   It should be primary used to define mapping from configurations to hosts.

conf/manifest/*::
   All other files in this directory are not directly used by cdist, but you
   can seperate configuration mappings, if you have a lot of code in the
   manifest/init file. This may also be very helpful to have different admins
   maintain different groups of hosts.

conf/explorer/<name>::
   Contains explorers to be run on the target hosts, see cdist-explorer(7).

conf/type/::
   Contains all available types, which are used to provide
   some kind of functionality. See cdist-type(7).

conf/type/<name>/::
   Home of the type <name>.

   This directory is referenced by the variable __type (see below).

conf/type/<name>/man.text::
   Manpage in Asciidoc format (nequired for inclusion into upstream)

conf/type/<name>/manifest::
   Used to generate additional objects from a type.

conf/type/<name>/gencode-local::
   Used to generate code to be executed on the server.

conf/type/<name>/gencode-remote::
   Used to generate code to be executed on the client.

conf/type/<name>/parameters/required::
   Parameters required by type, \n seperated list.

conf/type/<name>/parameters/optional::
   Parameters optionally accepted by type, \n seperated list.

conf/type/<name>/explorer::
   Location of the type specific explorers.
   This directory is referenced by the variable __type_explorer (see below).
   See cdist-explorer(7).

out/::
   This directory contains output of cdist and is usually located
   in a temporary directory and thus will be removed after the run.
   This directory is referenced by the variable __global (see below).

out/explorer::
   Output of general explorers.

out/object::
   Objects created for the host.

out/object/<object>::
   Contains all object specific information.
   This directory is referenced by the variable __object (see below).

out/object/<object>/explorers::
   Output of type specific explorers, per object.

tmp_dir::
   A tempdir and a tempfile is used by cdist internally,
   which will be removed when the scripts end automatically.
   See cdist-config(1).

TYPES
-----
The following types are available:

eof

for type in man7/cdist-type__*.text; do
   no_dir="${type#man7/}";
   no_type="${no_dir#cdist-type}";
   name="${no_type%.text}";
   name_no_underline="$(echo $name | sed 's/^__/\\__/g')"
   man="${no_dir%.text}(7)"

   echo "- $name_no_underline" "($man)"
done

cat << eof


OBJECTS
-------
For object to object communication and tests, the following paths are
usable within a object directory:

changed::
   This empty file exists in an object directory, if the object has
   code to be excuted (either remote or local)
