Add another codec to project

[mvala]

Can we have script, probably gsl script to generate another zxxx_msg in case user need 2 or more codecs?

If we will have such script. User can use zproto to generate simple generic zXXX project without zXXX_msg and later on one can append codec when needed.

or maybe to have xml file like https://github.com/zeromq/czmq/blob/master/model/project.xml for codecs

I'm not sure I understand the problem. Could you explain that (the problem)?

Problem 1: For example, i would like to create zXXX project (with directory sctructure zproto, czmq, zyre like) and i don't want to create any zXXX_msg yet. I want to have just generic project. In current zproto, i would use

scripts/create_project.sh

and i would remove zXXX_msg.h, zXXX_msg.c, ... and remove strings from autotools configuration

Problem 2: In my project i would like to have 2 codecs, zXXX_type1_msg and zXXX_type2_msg. And again, i would have to do it by hand to add another zXXX_type2_msg.

So approach, which czmq is doing i like very much because you add entry in model/project.xml class and autotools confiuration will be generated for you

## Option 0 - Adding a New Class

1. Add your new class to the src and include directories, edit czmq.h and
   czmq_selftest.c, and make a pull request.

I above example you have to put your header/implementation file to include/src dirs, but it zproto case one would just create myproj_msg.xml and everything (autotool config and header/implementation file) would be configured for him.

Is it clear now?

Proposal is to have script to generate simple generic project via

scripts/create_project.sh

and to have script

scripts/add_codec.sh <path to  myproj_user_msg.xml>

which would initialize/generate myproj_user_msg.h and myproj_user_msg.c and append correct autotool configuration

OK, so the focus here is creating new projects with arbitrary structure, which may include generated classes, or not.

What we put into zproto/skeleton is useful, but incomplete. What I like about it is that it creates the directory structure and LICENSE and so on. However the makefile generation we have in CZMQ/model is more powerful.

How about we split this off to zeromq/zproject, taking the model generators from CZMQ and adapting them? We can then use them in CZMQ, Zyre, zproto, zmon, etc.

I'd keep the same structure as zproto, so zproject/skeleton with the template, and zproject/src with code generation scripts. Thus the user builds and installs zproject -> /usr/local/bin and can then create more projects.

i think that zproject is the one i was looking for. :)

The project skeleton always felt a bit like a second class citizen in this project. I like this :+1:

OK, Martin, do you want to start then?

I have it on my todo list, but these days i am busy with my work. I will return to this as soon as possible

I'm closing this issue and rewriting it.
