subtree looks cool and may be part of the answer. However, in itself, it doesn't solve the problem of the general utility functions used by dseries. We still need to find them a place outside of Dynare git

Hi,
I think that Stephane's points are valid, however I still do not like solution (a). Solution (b) may work however, as Michel points out, it won't have a link between the files that are used commonly across future repositories.
I have looked into this a bit more, and am now in favor of using subtrees as opposed to submodules for the code that we're spinning off v (git subtree is standard in git 1.8, so you may need to update your git from wheezy-backports if you're using wheezy, where the git version is 1.7).
Manual: https://github.com/apenwarr/git-subtree/blob/master/git-subtree.txt
Tutorials: https://medium.com/@v/git-subtrees-a-tutorial-6ff568381844 http://blogs.atlassian.com/2013/05/alternatives-to-git-submodule-git-subtree
We should do some testing before committing to this solution, but my first test seems to work well. Essentially, we can use Stephane's solution (b) to do exactly what we want and use subtrees to take care of common code. Here's an outline of the solution I see:
- create dates, dseries, and reporting repositories, with master
branches (the standalone-unstable code), versioned branches (the standalone-stable code, which we may never actually need....it depends on if these projects every get lives of their own), and a dynare branch When we include these repositories in dynare, we will point to the dynare branch. To create each of these repositories, we will use the git subtree split command, to retain their development histories.
- in the dates, dseries and reporting repositories, include dynare.git
as a subtree. We remove all files that are not necessary for that individual repository. For example, I don't think we'll need a dynare subtree at all for reporting, whereas we'll need it for dseries (for the load_csv functions, name2tex, etc.). I'm not sure about dates, but we'll see with testing.
- when these files are updated in Dynare, we need to do a: git subtree
pull from within every repository that includes dynare as a subtree. This will merge all new changes in dynare into each repository that contains it as a subtree. This means that we won't have to remove files that we have already removed from the repository and won't have to worry about changes to files that have been removed. But, we'll have to remove any new files that have been added. This is added work, but so is git, and I think it's worth it to have have code that runs independently. Also, it's the only way I see of keeping track of changes in dynare without creating a "cepremap_toolbox" repository.
- on the dynare branch of each of these repositories, we keep only the
code that is in dynare-unstable (i.e. not the subtrees that they contain or the auxiliary files like README.md or setup scripts). This has the added benefit of allowing us to edit these files directly in dynare and do a: git commit; git subtree push directly from dynare.git to update both dynare and the subtree repository. We will then have to go to these repositories and cherry-pick the changes to the master (standalone-unstable) branch and any versioned branches (if they exist) if it is a bug fix.
I think this solves all of the problems we had been talking about. Is this ok with everyone?

Hi,
I do not think that it makes sense to put all the modules in one git repository. I do not perceive the advantage with respect to the previous situation (where all the codes were in the dynare git repository).Here are some arguments
(1) We (with Fred) already started to put particles in a separate git repository (it’s not in master yet). The reason for this move is that we believe that this code may be used for projects unrelated with DSGE or with Dynare. I do not understand why we should put this module in a common git repository, since this project has nothing in common with dates, dseries, …
(2) For me, the partition between different git repositories should not be a matter of size but of logic. If I want to use the dates tools I do not need to install the reporting tools or the particle filter codes. For instance, if I want to run a test suite specific to the dates module on a service like travis-ci, I just need to clone the dates and tests modules.
(3) By putting all the projects in a single git repository we loose some flexibility. For instance, I think that it would be no more possible to point to different branches/tags for the different submodules in Dynare (which is the case currently).
If the concern of Houtan is the distribution of the reporting tools (which depend on dates and dseries) or the dseries module (which depends on dates), we can think of simpler solutions:
(a) We can provide a small matlab installation script that downloads a snapshot of the required modules (basic users do not need to clone the modules with history).
(b) We can use different branches. For instance dynare can point to the master branch of reporting git repository, and we may have also a branch called standalone which is the same than master but with dates and dseries as submodules.
I favor the first solution (because when we distribute code we do not distribute the entire history)
Best, Stéphane.

Can you create the repository in Github? I'll take care of moving everything over and making sure it works.

After some thinking, my proposal is in fact to maintain a single GitHub repository called cepremap_toolbox in lack of a better name, that would contain, dates, dseries, reporting and utilities used both in Dynare and in these projects.
Then to stop the separate GitHub repositories dates and deseries
The idea that for the moment it is not a huge imposition for somebody who wants to use only our dates to download everything. If and when cepremap_toolbox becomes too large we will think about a better packaging.

Hi,
I am not sure that there is any advantage in creating a new git repository (with dseries, dates, … as submodules) which would be (if I do not misunderstand michel’s proposition) a submodule in Dynare… But I am sure that this would add more work. If I add a new method in dates and want to use it in Dynare, I need to:
(1) update the dates repository (2) update submodule dates in cepremap-tools repository (3) update submodule cepremap-tools in dynare repository
I would prefer not to pay step (2) each time I need to update dates, dseries, particles, … I think that a submodule for all the common utilities in Dynare would be useful, but we must decide what we put in it. I probably didn’t push this change (and I can revert it) but I finally put load_*_file_data.m routines in dseries.
Best, Stéphane.
