weblate & icu format

[dialonso]

Is your feature request related to a problem? Please describe.
Hello ! I would like to colorize the part of the text to be translated by translators because they are not able to know what should be translated
(e.g. {number, plural, =1{(# device)} other{(# devices)}} The translators had only to translate "device" and "devices" so I want thes two words to be colorized)

Weblate could definitely support this syntax and verify it.

On the other side please note that this is not the best way for handling plurals as it can not properly handle plural rules for many widely used languages, for example Russian or Arabic.

Thank you @nijel
I found it in the weblate doc (see screenshot1)
Nevertheless I can't configure it on my project, although having changed the flags by adapting it to "angularjs-format" (see scrrenshot2)
Do you have an idea ?

[nijel]

Probably because this is not a valid angularjs format string, we don't have support for ICU syntax right now.

[dialonso]

sorry to insist but our json value string is well an angularjs format string Plural Syntax
The syntax for plural based message selection looks like the following:

extract from https://docs.angularjs.org/guide/i18n#plural-syntax
{{NUMERIC_EXPRESSION, plural,
=0 {MESSAGE_WHEN_VALUE_IS_0}
=1 {MESSAGE_WHEN_VALUE_IS_1}
=2 {MESSAGE_WHEN_VALUE_IS_2}
=3 {MESSAGE_WHEN_VALUE_IS_3}
...
zero {MESSAGE_WHEN_PLURAL_CATEGORY_IS_ZERO}
one {MESSAGE_WHEN_PLURAL_CATEGORY_IS_ONE}
two {MESSAGE_WHEN_PLURAL_CATEGORY_IS_TWO}
few {MESSAGE_WHEN_PLURAL_CATEGORY_IS_FEW}
many {MESSAGE_WHEN_PLURAL_CATEGORY_IS_MANY}
other {MESSAGE_WHEN_THERE_IS_NO_MATCH}
}}

our string is {{number, plural, =0{none} =1{(# device)} other{(# devices)}}}
the flag is set angularjs-format

and as you see in capture screen, no plural was detected, have i missed something ?
(we import as json nested because json i18next failed)

thx for your help

[nijel]

Yes, but I can still repeat: this is currently not supported.

What is supported is AngularJS interpolation string

Hello @nijel ,
Can you tell me please, in which file in the weblate code could I find the part of TextField where Translators have to enter the text and validate before clicking on « save » button
I intend to modify the code by adding a function that will verify if the ICU format is valid or not
If not valid, an error should be returned by the function when translator click on « save » button
Like on the screenshots below

The existing AngularJS check is here: https://github.com/WeblateOrg/weblate/blob/master/weblate/checks/angularjs.py

This would deserve separate check with flag to enable it.

What about reusing editor from https://format-message.github.io/icu-message-format-for-translators/editor.html ?

We don't have support for ICU syntax right now

@nijel Is this the best issue to watch for checking for the supports? Or would be #2967 better? I started using Weblate for ARB files in Flutter and it uses the ICU format as the only option for plurals. #2967 makes it sound like a non-trivial implementation.

[nijel]

You can watch either. To big extent these are duplicates...

Some editor being capabale of syntax highlighting and linting should land as part of #4094, we can then start building the feature on top of that.

Is there any update to the progress of this? New to the platform however we are already heading deep into ICU/MessageFormat land

[nijel]

I don't think there has been any progress on ICU format support. Weblate is now using Prism for highlighting in the editor, adding ICU format to that should not be hard and could be a good starting point.
