Multilingual Gecko in 2017

The outline

In January 2017, we set the course to get a new localization framework named Fluent into Firefox.

Below is a story of the work performed on the Firefox engine – Gecko – over the last year to make Fluent in Firefox possible. This has been a collaborative effort involving a lot of people from different teams. It’s impossible to document all the work, so keep in mind that the following is just the story of the Gecko refactor, while many other critical pieces were being tackled outside of that range.

Also, the nature of the project does make the following blog post long, text heavy and light on pictures. I apologize for that and hope that the value of the content will offset this inconvenience and make it worth reading.

All Hands On Deck – How you can use your skills to contribute to Firefox 57 success

Firefox 57 in making

If you’ve been following Firefox development over the last year, you probably know that we’re hard at work on a major refactor of the browser, codenamed Quantum.

It’s been a very exciting and challenging time with hundreds of engineers bringing to life new concepts and incorporating them into our engineGecko. Those refactors, which will culminate in the release of Firefox 57, touch the very foundation of our engine and require massive changes to it.

We’ve moved the whole engine from a single to multi-process model which is perhaps the hardest possible refactor a major piece of software can go through. We’ve added a whole new systems level programming language, and we’re replacing major components of the engine such as styling and rendering systems. There are substantial changes to our networking layer and security layers as well as completely new components like a new extension ecosystem, virtual reality stack and APZ. We’ve added another new programming language as part of our JS engine and significantly remodeled our build process and infrastructure allowing for quick feature testing, telemetry analysis to understand how our changes impact users and many, many more things.

The changes are massive. This is the largest refactor to Gecko and Firefox in my 17 years of contributing to the project. But we’re not done yet…

One year with the Firefox OS L10n framework

For several years now, the Localization team at Mozilla has been working on a modern localization framework based on the following set of principles and architectural choices that we consider fundamental for the next generation multilingual UI’s.

  • Principle 1: Localizers should be in control of translations. The localization framework should be grammar-agnostic, whether it’s about grammatical cases, genders, or tenses.聽 Localizers should be able to use the entire expressive power of their language to author translations which create the best experience for the users.
  • Principle 2: Language fallback should be robust and graceful. When a translation is missing or broken the user should be presented with a translation into the next best language, given their preferences. There might be more than one fallback language.
  • Principle 3: Translations should be isolated and asymmetric if needed. The source language of the application should not define structure of the translations (e.g. the lack of pluralization in English should not make it impossible for other languages to use plurals in a given message).
  • Principle 4: The framework should embrace the Web. Localization should react to changes of the runtime environment (e.g. resizing of the app’s window, change of orientation, incrementation of a number of unread messages) and should add as little overhead for developers as possible.

Exactly one year ago, on April 8th 2014, Stas landed the initial rewrite of l10n.js – the localization framework used in Firefox OS. This set us on the path to enable the vision of a modern localization framework driven by the design principles outlined above.

Since then, we have a dedicated, two person team, working full time on advancing this vision and learning how to improve upon it in the process.

The full year of work has resulted in many important features being developed for the platform, including:

  • Language packs: Small packages that decouple language resources from the application allowing us to extend language coverage dynamically when users request it, even after the device has been already released on the market.
  • Pseudo-locales: Programmatically built language resources that emulate different languages allowing developers to test their applications for any multilingual problems before localizers have time to provide translations
  • Asynchronous l10n: Major shift away from using synchronous API’s for retrieving localizations from JavaScript. This results in clean, condition race free code that is easier to write and maintain. It also sets us on the path to enable runtime language fallback.
  • Security: While not traditionally big thing in localization, having an open runtime ecosystem of localizations requires us to make sure that translations cannot accidentally or maliciously impact our code and break it.
  • Error reporting: We’ve made major advancements to help developers and localizers find potential errors early. We reject malformed strings, report missing strings and duplicates, recover from exceptions in our code.

A couple weeks ago we have finalized the work scheduled for Firefox OS 2.2 and begun development for the next major release. The clean and reliable API has given us a good base to start implementing the remaining components of the vision behind L20n in this cycle.

For the current cycle we have scheduled:

  • DOM Overlays: Ability for a localizer to use HTML syntax in their translations and also provide whole localized DOM Fragments to be merged with developer provided skeletons via a secure algorithm. This increases the system’s security and empowers localizers to provide better translations.
  • L20n format: One of the last remaining pieces of the puzzle is the new file format that is designed to store localization data like multivariant strings, entities with values and attributes and variant selectors. This will allow us to start introducing new features to the system that are impossible using the current data storing formats.
  • Lightweight l10n contexts: Together with the whole platform, we want to make a heavier use of the concept of multiple small localization contexts to replace the single-context-per-app approach. It will improve performance and isolation resulting in easier maintenance.
  • API 3.0: Our current API still contains remaining pieces from the old, synchronous API that we’d like to remove. Together with lightweight contexts and on the path to WebAPI we will want to make sure to organize our events, methods and objects to fit the design of other W3C APIs.

With ever-growing understanding of the environment and how the web stack matures, we are also getting close to start extracting the core of our framework to offer for standardization, and that’s an exciting opportunity to fulfill the vision of both Firefox OS and L20n and bring the modern localization framework to the whole web, making it more multilingual and global.

Reducing MozL10n+Gaia technical debt in Firefox OS 2.1 cycle

Firefox OS is becoming a more mature platform, and one of the components that is maturing with it is the mozL10n library.

In 2.0 cycle, which is already feature complete, we introduced the codebase based on the L20n project.

The 2.1 cycle we’re currently in is a major API cleanup effort. We’re reviewing how Gaia apps use mozL10n, migrating them to the new API and minimizing the code complexity.

Simplifying the code responsible for localizability of Firefox OS is crucial for our ability to maintain and bring new features to the platform.

There are four major areas we’re working on:

  • mozL10n.translate – with introduction of Mutation Observer, we want to phase out manual DOM translation calls.
  • mozL10n.localize – this function is extremely hard to maintain and does enough “magic” to confuse devs.
  • mozL10n.get – manual l10n gets are the biggest cause of bugs and regressions in our code. They are synchronous, not retranslatable and badly misused
  • mock_l10n – many apps still use custom MockL10n class in tests, some even use real MozL10n code in tests. This makes testing harder to maintain and develop new l10n features.

We’re working on all four areas and would love to get your help.

No matter if you are a Gaia app owner, or if you’ve never wrote a patch for Gaia. If you know JavaScript, you can help us!

All of those bugs have instructions on how to start fixing, and I will be happy to mentor you.

We have time until October 13th. Let’s get Gaia ready for the next generation features we want to introduce soon! 馃檪

Localization framework changes in Firefox OS 2.0 and plans for 2.1

On Monday we branched Firefox OS 2.0 which is the first branch to contain a new localization library that has been developed by my team.

What landed for 2.0

Library landing and reactions

The library itself landed exactly two months ago. In order to avoid any potential regressions, we’ve put a lot of work to ensure that it matches the behavior of the old code that it replaced. I believe we can now claim a success, because with two months of baking on master we didn’t get any serious regressions that would require us to change anything in our code.

The new library comes with a lot of unit tests and is stricter than the old code, so we had to fix a couple of small bugs where code has been passing an object instead of a string to our API and one related to one test failing on old machine with too little memory. That’s been simple to catch and fix.

We also got a few requests to improve the console log output and error output that the library produces in order to simplify developers work.

New features


The major new thing that Stas completed in this cycle is the support for pseudo-locales. While this could be done with the old code, it was significantly easier with the new code thanks to some architectural decisions like separation of buildtime and runtime code.

Pseudo-locales allow developers to evaluate their UI’s localizability against an artificially generated english-like locale to catch any hardcoded strings. It also generates right-to-left locale for testing purposes. Before that, we’ve been relying on often outdated localizations that we kept with our source code. Now we can always test against fully generated pseudo localization.

mozL10n.once wrapper

Another new feature is the introduction of mozL10n.once wrapper. We identified that a lot of Gaia apps are waiting for localization to be ready before they initialize themselves. That makes sense since a lot of those apps want to work with UI and localized strings, but the challenge in asynchronous world is that you never know if your code has been fired after or before mozL10n is ready.

Because of that, simply setting an event listener and waiting for window.onlocalized event is not enough (what if it already has fired before your code was launched?). Developers were using mozL10n.ready wrapper, but the problem with that is that is has been designed to re-fire on reach retranslation which meant that your init code has been fired every time user changed language. That’s not an intended behavior, but admittedly a rare one. What’s worse is that we retained all the init code in memory.

Now, with mozL10n.once we can safely initialize code when l10n resources are available and free the memory right after that.

Uses of l10n API

On top of adding new features, we’ve been mostly busy investigating and improving how the default Firefox OS apps interact with localization API. That led to multiple design decisions including introduction of the described above mozL10n.once.

Once we got the new wrapper, we started analyzing bootstrapping code of each and every Gaia app and updating it to use the proper L10n API. Twenty two fixed bugs later, we’re done!

It’s incredible how much we were able to accomplish in just two short months. We feel much better right now about the bootstrap process and we have a clear picture on what we want to do next.

Use new navigator.languages API

Thank’s to Mounir’s work on navigator.languages API and implementation we were able to remove the only Mozilla specific API in mozL10n. That means that mozL10n should work in any modern browser now!

What we’re working on for 2.1

2.1 will be as ambitious for us as 2.0 was. The hashtag of the work is still #cleanup, but now it’s much more about modifying our API so that it’s more transparent to developers and requires less manual code in their apps.

entity.attributes become node attributes

First thing we were able to land is the transition away from assigning l10n entity attributes as node properties. We cleaned up the hacks that have been used and switched to entity attributes as node attributes.

DOM overlays

Next, we have one leftover from the previous change and that is an infamous innerHTML. We currently don’t have any clear way to inject localizable DOMFragment in Gaia. Fortunately, we have one that fits perfectly in L20n. It’s called DOM Overlays, and we’re working on getting them into mozL10n. That will allow us to further secure L10n API and remove any innerHTML calls.

Mutation Observers

Majority of localizability code in Gaia apps is related to localization of DOM nodes. With Mutation Observers we will be able to significantly reduce the amount of manual calls to mozL10n API and make majority of calls be just about settings data-l10n-id attribute with Mutation Observers doing the rest.

Not only will it reduce the use cases of mozL10n.translate and mozL10n.localize, but I expect to be able to cut by over 50% the number of manual mozL10n.get calls and manual operations that are currently used to set the result of that call into the node.

Mutation Observers will simplify Gaia code, reduce the amount of bugs related to language switching and get us closer to runtime l10n API that we want to offer for Gecko.


There are still some interesting edge cases around how code boostrapping relies on particular pieces of environment. Does your code need DOM to be interactive? Does it need l10n resources to be loaded? Or maybe you need DOM to be localized? All those events happen asynchronously and we currently do not have a clean way to guard against any combination of those that your init code may require.

We’re working on a bootstrapping wrapper that will allow app developers to simply define which pieces of environment should their initialization be blocked by.

That will further secure the app boostrapping process and limit the risk of condition races.


One part of the bootstrap puzzle is how we fire event when certain bootstrap things happen. Right now we fire window.onlocalized event that means that mozL10n resources have been loaded, but doesn’t tell us anything about if document’s DOM has been localized (and is ready to be displayed).

With the work on the new event, we’ll be able to remove the global one, and settle on triggering on event on document and one on mozL10n object. Did I tell you that we’re still cleaning up? 馃檪

Move mozL10n to document

We originally placed mozL10n object as a property on navigator object. Because our API is transitioning to be per-document, it becomes an inconsistency and an obstacle to keep mozL10n API on navigator object. It hardly fits the world with iframes, ShadowDOM and HTML Templates. We’re going to move it to document.mozL10n.

Remove inline l10n

One of the built time optimizations that we have in Gaia is called inline l10n. We store some portion of the l10n resources within each HTML file in order to localize the UI before it is displayed. It’s not very scalable, costs us memory and performance, but historically helped us prevent flashes of untranslated content. We hope to be able to remove this optimization in this cycle which will significantly simplify our internal code and give us some small memory and performance wins.

Is this L20n yet?

While we introduce L20n concepts into mozL10n, we’re still pretty far from being able to say that we support L20n API in Gaia. There’s a lot of work to do and it’s going to be a challenging work as we port L20n concepts to Gaia, and merge lessons we learned while working on Gaia into L20n spec and implementation. What we hope to end up with is a single codebase used in Gaia and offered to web developers.

It’s an exciting journey and I’m so happy to make Firefox OS’s localizability the most modern among all OSes!

L20n command-line toolchain

While we do hope that most of the work around l20n installations will have visual, GUI web tools, we also recognize that it’s important to provide simple, robust command-line tools that will cover the entire workflow.

For the l20n workflow to happen, we want to have a complete command-line toolchain that will automate common tasks required to operate and maintain localizations.

Behind this toolchain we provide a powerful API that localization and release tools will use, but the first consumer of those API will be the command-line based environment for l20n.

For this toolchain, we have three personas in mind:

  • a localizer
  • release driver
  • developer


Localizer should be able to start a new localization, stay informed about the status/completeness of his localization and have easy way to learn about updates. On top of that, he should be aided in navigating through the changes like new, modified or removed entities, get help in maintaining his localization between releases and work with the build team on marking which localization version is ready to be shipped.

Initially we want to provide four elements that will enable this:

  • on demand activated shell prompt customization that will provide contextual information while the localizer navigates around the l10n project
  • bootstrap command that will help initialize a new localization sandbox for a project
  • set of diagnosis tools like validator, completness check and localization status, all of which will analyze given localization and provide detailed information or what remains for the localization to be completed
  • an automated update tool that will help localizer keep the localization structure in shape, helping adding new strings, removing obsolete and provide information on the updated ones

The latter two concepts are powerful, and we have to be very careful when we design them. Each operation may harm the system, since we can easily loose the ability to review changes made by localizers in VCS history view if we apply changes that the localizer did not work on, or we can hide from the localizer the contextual information by removing entities that became obsolete, but their value has been reused in a new entity added just next to the old one.

All this kind of stuff has to be taken into account and we want to aim for a balance between simplifying day-to-day localization work, and maintaining VCS friendliness and sense of control that a localizer must have over his localization project.

Release driver

As with a localizer, we want to provide methods to automate common tasks, like selecting locales for a release, learning about status and progress of multiple locales at once, accepting new locales from localizers and batch updating locales with changes.

In order to achieve that, we want to provide:

  • a custom shell prompt that will aid release driver while he navigates between localization projects
  • scripts that will make it easy to analyze the status of localizations and validate them
  • tools that will allow release driver to maintain the list of locales and their version, to be released with a given version of the product
  • a script that will take a small “l10n patch” like a number of new entities, or value changes, and apply it across multiple locales


For the developer, we want to make sure that it’s easy to make his code localizable and maintain it that way.

This means that we want to make it easy to add new entities manually and verify that they work with tests, that we can extract entities from code where possible (like – XML), and it’s easy to spot hardcoded strings.

For this, we plan to provide the following tools:

  • a validator that outputs unit-test readable outcome statuses, so that unit-tests can be written against localizable code
  • an extractor for simple extracting and maintenance. The extractor should be able to help developer clean l10n files by removing strings that are no longer used in the code.
  • a tool that generates dummy test locale which enables the developer to visually find hardcoded strings

We want to make the whole environment project independent by allowing each project to define how process like bootstrapping, extracting should exactly work, where the l10n resources are stored and others.

The first set of tools will be aimed to help localizers, then we’ll work on tools for release managers and developers will come after that.

We’re in the process of writing API’s and designing the syntax for those commands. You can find the document with a proposal and the current source code here.

“Definiowanie w艂asno艣ci” autorstwa Paula Grahama

Marzec 2012

Jako dziecko przeczyta艂em ksi膮偶k臋 z opowie艣ciami o s艂ynnym osiemnastowiecznym s臋dzim z Japonii o imieniu Ooka Tadasuke. Jedna ze spraw kt贸re rozs膮dza艂 zosta艂a wniesiona przez w艂a艣ciciela baru z jedzeniem. Biedny student, kt贸ry m贸g艂 tylko pozwoli膰 sobi臋 na ry偶, jad艂 go, jednocze艣nie delektuj膮c si臋 zapachami z kuchni dochodz膮cymi z tego baru. W艂a艣ciciel chcia艂, by student zap艂aci艂 za zapachy, kt贸re dawa艂y mu przyjemno艣膰. Student krad艂 jego zapachy!

Ta historia przypomina mi si臋 za ka偶dym razem, gdy s艂ysz臋 o RIAA i MPAA oskar偶aj膮cych ludzi o kradzie偶 muzyki i film贸w.

Brzmi dla nas absurdalnie, by traktowa膰 zapachy jako w艂asno艣膰. Ale mog臋 wyobrazi膰 sobie sytuacj臋, w kt贸rej kto艣 m贸g艂by 偶膮da膰 op艂at za zapachy. Wyobra偶cie sobie, 偶e 偶yjemy w bazie na ksi臋偶ycu, gdzie powietrze sprzedawane jest na litry. Mog臋 sobie wyobrazi膰 dostawc贸w powietrza dodaj膮cych aromaty za dodatkow膮 op艂at膮.

Pow贸d, dla kt贸rego wydaje nam si臋 absurdalne, by traktowa膰 zapachy jako w艂asno艣膰 wynika z tego, 偶e taki system by nie dzia艂a艂. Na bazie ksi臋偶ycowej jednak, m贸g艂by.

To co jest uznawane za w艂asno艣膰 zale偶y od tego co jeste艣my zdolni uzna膰 za w艂asno艣膰. A to nie tylko mo偶e si臋 zmienia膰, to si臋 zmienia. Ludzie zawsze (dla pewnych definicji cz艂owieka i zawsze) traktowali ma艂e obiekty noszone przez osob臋 za w艂asno艣膰. Ale ludy zbieracko-艂owieckie nie traktowa艂y ziemi, na przyk艂ad, jako w艂asno艣ci w takim rozumieniu jak my. [1]

Powodem, dla kt贸rego tak wiele ludzi uznaje, 偶e w艂asno艣膰 ma jedn膮, niezmienialn膮 definicj臋, jest to, 偶e ta definicja zmienia si臋 bardzo wolno. [2] Tak si臋 jednak sk艂ada, 偶e znajdujemy si臋 w艂a艣nie w 艣rodku takiej przemiany. Koncerny muzyczne i studia filmowe dystrybuowa艂y to co tworzy艂y jak powietrze przez tuby na stacji ksi臋偶ycowej. Ale wraz z nadej艣ciem sieci, przenie艣li艣my si臋 na planet臋, kt贸rej atmosfer膮 mo偶emy oddycha膰. Dane przenosz膮 si臋 teraz jak zapachy. Koncerny i wytw贸rnie, przez po艂膮czenie my艣lenia 偶yczeniowego i kr贸tkoterminowej zach艂anno艣ci, ustawi艂y si臋 w pozycji tego w艂a艣ciciela baru, oskar偶aj膮c nas wszystkich o kradzie偶 ich zapach贸w.

(Powodem dla kt贸rego u偶ywam okre艣lenia “zach艂anno艣c kr贸tkoterminowa” jest fakt, 偶e prawdziwym problemem z wytw贸rniami i studiami jest to, 偶e ludzie, kt贸rzy nimi kieruj膮 s膮 wynagradzani premiami, a nie akcjami. Gdyby byli nakr臋cani akcjami swoich firm, szukali by sposob贸w by wykorzysta膰 przemian臋 technologiczn膮, zamiast walczy膰 z ni膮. Ale tworzenie nowych rzeczy trwa zbyt d艂ugo. Ich premie zale偶膮 od przysz艂orocznych przychod贸w, a najlepszym sposobem by je podnie艣膰 jest wyci膮gni臋cie wi臋cej kasy z tego co ju偶 robi膮.)

Co to znaczy? Czy ludzie nie maj膮 prawa, by nalicza膰 za to co tworz膮? Na takie pytanie nie istnieje prosta odpowied藕 typu tak lub nie. Ludzie maj膮 prawo nalicza膰 za kontent kiedy naliczanie za kontent dzia艂a.

Ale przez “dzia艂a” mam na my艣li co艣 bardziej subtelnego ni偶 “kiedy im si臋 uda”. Mam na my艣li kiedy ludzie mog膮 nalicza膰 za kontent bez zak艂adania kaftan贸w bezpiecze艅艣twa na ca艂e spo艂ecze艅stwa, by m贸c to zrobi膰. Ostatecznie, firmy sprzedaj膮ce zapachy na ksi臋偶ycu mog艂yby nadal to robi膰 na Ziemi, gdyby uda艂o im si臋 lobbingowo wymusi膰 prawa zmuszaj膮ce nas wszystkich do oddychania przez ich tuby tak偶e tutaj, cho膰 nie jest nam to ju偶 konieczne.

Szalone kroki prawne, kt贸re podejmuj膮 te wytw贸rnie i studia w艂a艣nie tak wygl膮daj膮. Gazety i magazyny maj膮 podobnie przer膮bane, ale one przynajmniej odchodz膮 z wdzi臋kiem. RIAA i MPAA zmusi艂yby nas do oddychania przez tuby gdyby mog艂y.

Ostatecznie, wszystko sprowadza si臋 do rozs膮dku. Kiedy naruszasz system prawny przez pr贸b臋 wykorzystywania masowych pozw贸w przeciwko losowo wybranym ludziom jako formy przyk艂adowego ukarania, albo lobbujesz za przepisami, kt贸re zepsu艂yby Internet gdyby uda艂o si臋 je przeforsowa膰, to jest to ipso facto dow贸d, 偶e u偶ywasz definicji w艂asno艣ci kt贸ra nie dzia艂a.

To w艂a艣nie w tym miejscu okazuje si臋, 偶e fajnie mie膰 dzia艂aj膮ce demokracje w wielu niezale偶nych krajach. Gdyby 艣wiat mia艂 jeden, autokratyczny rz膮d, wytw贸rnie i studia mog艂yby kupowa膰 prawa definiuj膮ce w艂asno艣膰 jako cokolwiek by chcia艂y. Ale na szcz臋艣cie s膮 wci膮偶 na 艣wiecie kraje, kt贸re nie s膮 koloniami praw autorskich Stan贸w Zjednoczonych, a nawet w USA, politycy nadal obawiaj膮 si臋 obywateli, je艣li tych zbierze si臋 wystarczaj膮co du偶o. [3]

Ludzie, kt贸rzy rz膮dz膮 USA mog膮 nie by膰 zachwyceni kiedy obywatele lub inne kraje odmawiaj膮 nagi臋cia si臋 do ich woli, ale ostatecznie le偶y to w naszym interesie, aby nie istnia艂 jeden punkt, kt贸ry ludzie chc膮cy opakowa膰 prawo, by s艂u偶y艂o ich interesom, mogliby zaatakowa膰. W艂asno艣膰 prywatna jest niesamowicie potrzebn膮 ide膮 – mo偶liwe, 偶e jednym z najwi臋kszych wynalazk贸w. Dotychczas, ka偶da jej nowa definicja przynosi艂a nam rosn膮ce bogactwo materialne. [4] Wydaje si臋 by膰 rozs膮dnym, by za艂o偶y膰, 偶e najnowsza te偶 to uczyni. By艂oby katastrofalne gdyby艣my wszyscy musieli korzysta膰 z przestarza艂ej wersji tej definicji, tylko dlatego, 偶e kilku pot臋偶nych ludzi jest zbyt leniwych, aby przej艣膰 na nowsz膮.

L20n – what to add before 1.0

As I mentioned in my last blog post, we’re narrowing down the list of features that we’re willing to consider for inclusion into L20n 1.0 prior to its freeze and release.

Here’s the list:

Name Driver Target Milestone
difference between entities/macros from the resource and variables provided by the developer stas 1.0
difference between public and private attributes/entities gandalf 1.0
default values for hashes/arrays gandalf 1.0
globals namespace gandalf 1.0
import command gandalf 1.0
conditional blocks gandalf 1.0
value as ID (gettext mode) stas ?
string as ID (simple gettext mode) stas ?
key as string stas ?
relative referrals gandalf 1.0
dependency list gandalf 1.0
computer readable comments gandalf ?
multi-language resource files gandalf 1.0
Switch expression gandalf ?
attribute indexes stas 1.1
nested indexes gandalf 1.0
Expression errors gandalf 1.0
workflow gandalf 1.0
resource file syntax stas (support from: kaze, fantsai) 1.0
forbid referencing public entities stas ?
Macro attributes gandalf ?

All of those features represent some feedback item we got and we’re trying to evaluate it ASAP in order to finalize the parser/interpreter couple and work on the workflow toolchain for L20n 1.0 next.

If you want to discuss any of the items, join our localization-20 group and start a new thread for each feature.

If you want to add a new feature to be considered, start a wiki article in L20n/Features namespace.


L20n, feedback round

Last months have been extremely busy for L20n. I basically focused 100% of my time on the project, driving simultaneously multiple aspects of the project to completion.

L20n is a very complex project, not only technically, but also socially. Localization technologies have always been of minor importance for most of the software world so we never really develop technologies that could anyhow match the complexity of the human languages. The most common mindset, even among those who have to deal with localization, is that you can get “most of the stuff” done with simple key-value pair lists where English string is a key, and target localization string is a value.

It’s a bit like claiming that most of Firefox front end could be written in BASIC.

L20n is on the other side of the spectrum. It brings the localization technology to the new level, and in result breaks almost all paradigms of what people are used to do with l10n and breaks how it “usually works”.

In result, the major challenge when helping someone learn what L20n is, is to convince the person that she has to stop trying to match its components to the concepts the person knows from other l10n frameworks. It will just not do.

The reward is that once you get beyond the game of “how does L20n relate to Gettext / DTD / Properties?” people get into the “Oooh!” moment and what follows is a litany of ideas of what would be nice to have if we are about to reinvent the localization technologies. I love it 馃檪

As many project leaders before me have observed, getting close to a target milestone always turns you from a visionary leader that sets the goals and drives them to completion into some sort of a butcher that says “no” to everything except the most crucial additions in the fear of never ending cycle of adding more and more without getting your project released.

So here we are. For the last month we’ve been working pretty close with several projects – Boot 2 Gecko, Jetpack, Firefox – and we got plenty of feedback, from minor additions to major suggestions. Now is the time to narrow down the list of changes we’re ready to incorporate for 1.0, close the list, work toward the release, and push everything else back to L20n:Next.

In the next blog post I’ll list the proposals and the status of the discussion on those.
