Odoo fontawesome v4 to v5 automatic file transcripter

Fontawesome v4 to v5

Applicable to Odoo XML and JS files. See LICENSE file on for full copyright and licensing details.

The script was applied to the entire odoo codebase and was able to automatically convert most icons in a few seconds.

Warning

There are a few patterns the script doesn't detect or migrates wrong. They require your attention.

• javascript tests click('.i.fa.fa-star-o')
• code-controlled icons $('.fa-star').toggleClass('fa-star').toggleClass('fa-star-o')
• css selectors .fa-star { color: gold }
• html classes when a non fa class is put in between fa classes class="fa fa-fw mt4 fa-star-o" (wrongly translated as fas fa-fw mt4 fa-star-o)

You can find most of those icons by scanning the code for words containing a -o suffix, here is a regexp: \w-o\W.

"""
Because it's quite a mess, here are some insights : 

1) v4 font-awesome had a single "fa" prefix and one font name per icon
2) v5 font-awesome has multiple prefixes ('fas', 'far', 'fab') that
   serve as icon style, several icons share the same name. An icon is
   identified by the pair (icon style, icon name).
4) Most v4 icons suffixed with "-o" now have the far style without this
   suffix. We translate them (along with all other "special" fonts)
   using the fontmap json file.
3) Most v4 icons have the fas style in v5 with the same name, they are
   not covered in the fontmap.json file and are translated by the
   '*_generic_re' regexps bellow.
5) Beside icon style and name, each icon can be modded to be larger,
   smaller or animated. Those mods don't change between v4 and v5.
