Add i18n support

[Steffen Hoffmann]

I'd like to see support for i18n added to this plugin.

As I prepare an important application for an fully internationalized Trac environment based on Trac 0.12.x or 0.13dev I'll provide the changes on my own. As usual I aim at adding message catalogs to the Trac plugin l10n project. After some lessons learned with other plugins before, I'll directly aim at a backwards-compatible version, so that we can stick to the 0.11 branch label and just add «works with 0.12 too».

Anyone else interested? Join in and contact me directly, please.

I've already started work on this, awaiting further information after a ​call for action to the t-h.o mailing-list.

[Steffen Hoffmann]

Most of the work done by now, but this is still an enhancement, right?

[Steffen Hoffmann]

Of course I'll go and release changes soon, after I've been awarded to maintain this plugin by now.

[Steffen Hoffmann]

Been quite some time since I've started that work, not dreamed to do so many other things to this plugin, before I'd be finally able to add i18n. But this is point in time approaching at least now.

[Steffen Hoffmann]

(In [10021]) TracFormsPlugin: Add basic code and markup for i18n support, refs #8258.

This is accompained by a code cleanup especially aimed at Python docstrings. An ancient typo in cmd_page of TracFormProcessor has been fixed as well.

[Steffen Hoffmann]

(In [10022]) TracFormsPlugin: (i18n) First message extraction, refs #8258.

Unified and shortened related msgids of TracForm exceptions a bit. I18n markup has been tested with the German translations included here.

[Steffen Hoffmann]

(In [10023]) TracFormsPlugin: Fix regression introduced by changeset [10021], refs #8258.

Custom submit_label values have been overwritten by optionally localized default label before.

[Steffen Hoffmann]

(In [10079]) TracFormsPlugin: Add basic history browsing capability, refs #3445, #4759 and #8258.

Fix code around TracForms db handling after using tuple for 'src'. Plugin now contributes to parent resource's context navigation, db interface is grown by a method for reverse-lookup of forms and the 'Form' resource is getting extended to provide more information too, everything needed to establish infrastructure for history browsing. With the addition of templates we need to extend i18n capabilities as well. This is the base for later adding form reset and delete/purge functions.

[Steffen Hoffmann]

(In [10080]) TracFormsPlugin: Partial msgid and translation update, refs #8258.

Msgid changes are done to finally unify similar messages. While extraction from templates is working, content is still omitted for being too preliminary by now.

[Steffen Hoffmann]

(In [10093]) TracFormsPlugin: (i18n) Unify quoting, impove prematurally ended msgid, refs #8258.

Make sure to use double-quotes only as this is recommended i18n msgid style.

[Steffen Hoffmann]

(In [10094]) TracFormsPlugin: (i18n) Extract new msgids and update German translations, refs #8258.

Minor code clean-up is do to build another msgid, that is used twice.

[Steffen Hoffmann]

(In [10099]) TracFormsPlugin: Reorganisation for the main IRequestHandler, refs #8258.

Drop the 'history' action in favor of a new default form view, making use of the improved URL parser from [10096] for the '/form' base URL. And again new i18n msgids: Context-nav links show that change as well.

[Steffen Hoffmann]

(In [10101]) TracFormsPlugin: (i18n) Extract new msgids and update German translations, refs #8258.

[Steffen Hoffmann]

(In [10131]) TracFormsPlugin: (i18n) Update msgids and German translations, refs #8258.

[Steffen Hoffmann]

(In [10143]) TracFormsPlugin: Releasing version 0.3, pushing development to 0.4, closes #3445, #3550, #3741, #4759 and #8258, refs #3388 and #6993.

This is a major release requiring a Trac environment upgrade.

While the parser logic remains unchanged, there is a lot new supplementary funcionality to make TracForms behave more like the existing Trac core resources (ticket, wiki, attachment, ...).

This version performs a series of non-trivial db schema changes, that especially may leave traces of stale forms (i.e. recorded for wiki pages, that don't exist anymore). So please make sure to read the changelog, BACKUP your environment(s) before installing this version as usual and check the new db tables forms, forms_fields and forms_history after upgrading.
