Replace internal Interlis parser with library

[m-kuhn]

We currently have an internal Interlis parser which is used for example to list available models within an interlis file. This regex based parser works good enough, but if possible, it would be nice to replace it with a dedicated library.

Options:

1. ili2c java edition
2. ili2c C/C++ edition
3. custom Python library

Options 1 or 2 are preferable. Both of them need a wrapper layer to be available from within Python. Option 2 is not yet available and the deployment needs to be checked, possibly through pypi.

Welche Funktionalität von ili2c-java braucht es alles? Auch die ilirepository-Funktionalitäten? https://github.com/claeis/ili2c/tree/master/src/main/java/ch/interlis/ilirepository

Braucht es zu guter Letzt nicht auch ili2db ohne "Java"?

[m-kuhn]

• The ilirepository functionality would be interesting too. But it's not as critical because it's regular XML where solid parsers are available for every platform.
• ili2db as a library (if the backend is in java is a detail question in the end) would also be nice to have, mostly for better semantics for error reporting. I.e. replacing parameter/stdin/stdout communication with an api.
• ili2c as a library would make it possible to drop the regex based Interlis parser

Can you point me to the code to your "internal Interlis parser"?

The "internal interlis parser" is here.

Note: it's not "mine", it's open source ;)

For reference, we already have an ili2db through api issue
