Since there's no OS X friendly way to localize the chrome strings (i.e., localizing requires re-packaging for one specific language), we should translate chrome strings on the fly. Basically, for each chrome string we get, we should do the following: - Parse it to see if it matches a known chrome string - Map the match to a key, and pass that key into NSLocalizableString - Substitute the returned string for the localizable part of the original string While this is slightly fragile (requiring code changes when embed.jar strings change), it's the only way to get complete localizations through the OS X localization system.
Putting on the 0.9 list.

Simon would you have time to look at this bug ?
Shouldn't the localizations be using localized embed.jar files? I don't think we want on-the-fly translation, as it will be fragile in the face of string changes.
Several reasons why we should try to solve this bug: 1 - "there's no OS X friendly way to localize the chrome strings (i.e.,localizing requires re-packaging for one specific language)" 2 - point 1 breaks the habit of having a single multilingual package 3 - working separately on jar files forces localizator to use more tools than now we use: we haven't a lot of horsepower, so we need to keep things simple; we have done a lot of work in streamlining the l10n process in about 2 years 4 - in over a year nobody on the caminol10n mailing list has come up with a way to handle localized embed.jar files, so we... simply still don't know how to do it (ok, we can probably easily fix point 4...) 5 - Frailty is an issue we can handle, I think. We use to work on localizing nightlies before release, so if a string is broken, we'll probably catch it before release and we'll only have a few nightlies or alphas with issues.
First off, from an end-user pov, I think it's already silly that there's a separate Camino MultiLang download necessary for an application that prides itself as a well-integrated app that behaves according to Mac OS X norms. From a "technical" pov, I understand the issues; it's not the way the Mozilla codebase is set up. I'm not aware of other non-Moz multilingual Mac OS X apps that act this way (even NeoOffice/J, based on OpenOffice.org which is set up in a similar manner to Mozilla, manages to ship the 12 most complete--of 40--localizations in one app), though. I would go so far as to argue that Camino 1.1 should ship as one app with all available localizations and the separate MultiLang app discontinued. As for frailty with string changes, how often have those strings changed? Once a quarter on average (i.e., each of the three files touched once per quarter)? Maybe twice if someone didn't put the comma in the right place the first time? In that respect, they seem no different than Camino's Cocoa UI, where every once in a while some new text UI is added, and occasionally the checkin comes without requisite changes to Localizable.strings. The L10N team localizes a nightly or alpha, notices the missing/unlocalized strings, and files a bug; eventually, the bug gets fixed. Further, in the immediate future, we'll be releasing off of a shared "stable" branch which 1) supposedly won't branch until major UI/string changes are complete and 2) will have a L10N freeze at some point, anyway (but I'd assume Gecko/Necko changes would fall under the first category and toolkit-app-specific changes will make up the second). If we're going to continue to more-or-less track the toolkit timelines to leverage shared work and all that stuff for the medium-/long-range future, I don't see how string volatility/fragility is a "real" problem. If it turns out that there's no way to engineer an on-the-fly translation system for chrome, that's one thing, but I don't see any significant reasons offered why we should not try to create such a solution. P.S. Apologies if this sounds like a smart-aleck rant; it's not meant to. :-)

I agree on that one. It's the easiest solution to have a more than one language in one application.
(In reply to comment #15 and comment #14) > Yep, but size grows when adding more labguage, hence the english for evryone and > the multilanguage for people not willing to use English. Add the fact that we (caminol10n) have been able only once (last time actually) to synchronize with the English release. As I said, we're trying to keep the l10ns update process simple in order to mantain this no-gap situation (along with other reasons). Until we are not sure to match Camino's release schedule everytime, I think it's good to have one official (English) package and an evolving multilingual package. I really hope this goal can be met by 1.0 on. > > As for frailty with string changes, how often have those strings changed?

On a release branch, there is not much change. On trunk it depends. Uhm, but here we're talking about the embed strings, that shouldn't involve "native" portions like the pref panes. I guess changes there should have a small bottleneck effect on development, especially once we have find out how to do it for the existing strings.

Any new suggestions here? How hard would it be to implement Stuart's method? Do we have access to the keys that define these strings in their .properties files, or are we just fed the matching string?

FYI, there's a very interesting post om caminol10n that sounds promising as a way of addressing part of this problem (the MathML strings live in Camino.app/Contents/MacOS/res/fonts/mathfont.properties, not embed.jar): http://mozdev.org/pipermail/caminol10n/2006-July/001664.html It's not as elegant as turning them into localizable.strings, but it sounds like it can be done now.

Can this go official ? -- Paulo
There might even be a way to automate Igor's procedure, since we can now specify our own content to be placed in embed.jar. cl
I tried a trilingual embed.jar (English, French, and Igor's Russian), and my English Camino was suddenly giving me Russian chrome strings :-( AFAICT, Gecko is using the chrome locale that's listed last in the installed-chrome.txt list, rather than matching the language of the UI or whatever.
(In reply to comment #26) > AFAICT, Gecko is using the chrome locale that's listed last in the > installed-chrome.txt list, rather than matching the language of the UI or > whatever. Do you think Gecko behaviour is fixable, or should we abandon the idea of localizing the jar and go back to the "on the fly" translation method?
While there might be workarounds that are able to "fix" this bug, they'll never be as ideal as the actual fix stated in comment 0. I'm retargeting this bug for 1.2 as it would probably be a large code change. Ludo, care to look at this?
Target Milestone: Camino1.1 → Camino1.2
I have an idea here. According to comment 23 it is possible to merge more localizations into the jars. So the remaining problem is how to make Camino change installed-chrome.txt to the current lang. Well, maybe we can check at startup of Camino what the current locale is, and write that into installed-chrome.txt. This would have to be done before XPCOM is initialized and that file has been parsed. Taking to investigate. If someone has a (test-)localized embed.jar lying around, please attach it; that would make this easier for me.

Maybe this can be fixed in the same way that bug 331576 can('t right now).
The solution should be to set intl.locale.matchOS to true. This works for Firefox. The thing is FireFox is not using embed.jar, but more files. Why do we use Embed.jar ? is embed.jar localized anywhere in the mozilla tree ? Or do we need to stop using embed.jar and start using the equivalent chrome files for necko/layout and other services Camino uses.
I bet this would get resolved if you move to xulrunner for your embedding story. At least partly.

Attached patch sttres WIP 1 (obsolete) — — Splinter Review
Here is my WIP for the core patch that is needed in strres. This patch is needed because the call to |nsStringBundleService::Init()| is called before any of the init embedding code is fired up (where we register our own service). Without this patch, an embedder can't override the |nsIStringBundleOverride| service with the Component manager.
Does any of the regular apps use the overrides? Another question I had is on timing, would it suffice for the string bundle service to look for the overrides on first use? Is there any chance for reference count mishaps if a string bundle already exists when a embedder comes up with the idea to call this routine twice, after changing the component associated with the contract ID?
> Does any of the regular apps use the overrides? The only other class in the 1.8 tree that uses this interface is | nsStringBundleTextOverride|. It is designed to look for a file called custom-strings.txt. According to a comment in |nsStringBundleTextOverride::Init()|, it looks like if the class can't find the "custom-strings.txt" file, it bails out of service registration. I searched through the 1.8 branch and could not find a single instance of "custom-strings.txt". Also according to the nsIStringBundleOverride idl, this comment indicates that the interface is designed for embeddors (only?): // to be implemented by an embeddor that wants to override some strings > Another question I had is on timing, would it suffice for the string bundle > service to look for the overrides on first use? Thats definitely another option, my fear is that (I haven't validated this yet) some class calls the service and asks for a string before our embedding initialization takes place. > Is there any chance for reference count mishaps if a string bundle already > exists when a embedder comes up with the idea to call this routine twice, after > changing the component associated with the contract ID? Yes, I need to addref and deref |mOverrideStrings|.

This patch introduces the Camino fix, adding a new interface that looks for a string to override in Localizable.strings and passing a gecko version (if one exists) back to the caller.
Mass un-setting milestone per 1.6 roadmap. Filter on RemoveRedonkulousBuglist to remove bugspam. Developers: if you have a patch in hand for one of these bugs, you may pull the bug back to 1.6 *at that point*.

Attached patch Patch V1 — — Splinter Review
Here is the Camino patch now that the intl/stress core patch has landed. This just introduces a service to the Component Manager that listens for a localized gecko string to override. When a call is made, we try and see if it is defined in the Camino Localizable.strings file. We only tell gecko not to use its string if we don't have a overridden version.

Maybe we want to prepend some string constant to the Gecko key value to reduce the possibility of conflict? r+ either way, just tossing an idea out there.
