Re: New library to migrate Odoo module code "odoo-migrate"

PS: As long as the tool strictly works on the workdir and does not attempt to interfere with database migration, the scope is clear, and the need is there :)

Hi Silvain,

there was coming something to my mind, I'd like to share.
Some time ago, I worked with pybowler, which is a code transformar on the python grammar level.
Like regex without the "regular" in it.

It is super convenient to write certain transform scripts, And I'd suggest to use it for your library, as it is very easy to extend and very powerful.
It would also be easy to make contributions and once community grows familiar with python grammar expressions, then it might unleash unprecedented productivity for OCA maintenance tasks and beyond.

Based on facebook's excellent pybowler library.

Best Regards,

David A.

+1 stephane comment about standalone
+1 about resist feature creep

Hasn't there been some proposal going around to have OCA-libs as a Github orga for those standalone projects to be hosted / promoted?

There is python-xmlsig and python-xades from Eric and many others too.

+1 to keep it a standalone project. I'd rather see the good parts of OCA/maintainer-tools become standalone projects too.

Regarding growing features, be strong Sylvain, resist scope creep :) Do one thing and do it well!

Dear OCA Contributors,

I am working on a migration from 8.0 to 12.0.
For that purpose, I had to migrate a lot a modules. (about 50 OCA modules, and >100 custom modules)
A lot of changes are very recurrent, and automatable. (removing python2 header, renaming into, changing import).

I began to make some scripts, and finally began to create a new python3 library, to make that work. The name is "odoo-migrate" and the description is available here and can be installed with the command
pip3 install odoo-migrate

Once installed, you can run the following command (other options are available)
odoo-migrate -m my_module_name -i 8.0 -t 12.0

It is based on the OCA recommendations available on this wiki.
In addition to performing recurring operations,
- the library also execute the weird format-patch command which I never remember (if asked).
- it displays some warning if some patterns are found. (for example, if "ir.values" is found in a module 11+)
- it calls black for recent version
- it realize commits

1) If you're interested by such tool, you can review or test this project.

2) If you want to contribute, feel free, especially if you love regular expressions. It is still WIP, and there is a lot of work to do, like making change in xml file. (replacing openerp + data by odoo tag). Also adding test and plug with travis could be great.

3) if some OCA members are OK, I can transfer this project under OCA umbrella.

thank you for your feedback.

kind regards.
