[[Category:Configuration]]
This is some information about the configuration system that does not completely reflect the current configuration system.
Sett Configuration to get information about the current system.

== General ideas ==
* as much as possible independant from the system (windows/unix)
* one file with multiple configurations (eg. debug, release build)
* include/exclude as regexp pattern
* global ignore patterns (eg. cvs/svn)
* include other configuration files (eg. to add a library just include the config file of the library)
* relative paths
* actions before/after run/compile (eg. start a server)

=== Things to implement ideas ===
* conditions (if windows then ... elseif unix then ... end)
* variables (user and predefined)
* inheritance of configuration
* C code to compile (when wrapping C API:s or optimizing code)
* Flags to C compiler and linker

=== Other ===
* convert old ace files into new format
* *.epr vs *.ace
* [[ProjectFiles]]

== Possible implementation layout ==

Some more information are available here: http://www.ise/tools/public_zone/index.php?op=dl&path=/home/patrickr/public_html/Public/project_configuration.pdf (Part with two config files has changed to only one config file.)

A system consists of multiple targets. A target can extend another target. A target can have some libraries, assemblies, clusters and override clusters.
A library has an associated target. A cluster can have a parent cluster. An override cluster has a some groups it overrides.

== Questions and Problems ==

*Specify use of other clusters? '''Yes'''
*Variables? '''If not defined, take environment variable.'''
*Path relative to ace file? '''Yes'''
*When are two libraries the same? '''UUID: http://www.famkruithof.net/guid-uuid-random.html'''
=== Multiple library usage ===
====Problem====
<pre>
System Application

library A
library B
</pre>
<pre>
System A

library C
option Yes
</pre>
<pre>
System B

library C
option No
</pre>
We have a conflict for the option on library C.

====Solution====
If the library is directly used in Application, use the this options, otherwise use the options of the Application system.

===File pattern===
The file pattern match against the relative path in unix format in a cluster.
e.g. if the cluster is in C:\mycluster

<table border="true">
<tr>
<th>Pattern</th>
<th>Matches</th>
</tr>
<tr>
<td>
storage/table
</td>
<td>
C:\mycluster\storage\table\*
C:\mycluster\storage\table.e
C:\mycluster\something\storage\table\*
</td>
</tr>
<tr>
<td>
^/storage/table/
</td>
<td>
C:\mycluster\storage\table\*
</td>
</tr>
<tr>
<td>
^/.*/test/
</td>
<td>
C:\mycluster\a\test\*
C:\mycluster\b\test\*
</td>
</tr>

<tr>
<td>
/test/
</td>
<td>
C:\mycluster\a\test\*
C:\mycluster\b\test\*
C:\mycluster\something\table\test\*
</td>
</tr>
