Lots of people use RLT language, please add it.

Guys, do you have any ideas how we can understand a note is written in RTL language?

[streamich]

Maybe we should not detect if language per note, but per user. If user's browser settings suggest he is using RTL language then the whole app should rearrange itself.

var language = window.navigator.userLanguage || window.navigator.language;

Also found this on Stackoverflow:

function isRTL(s){           
    var ltrChars    = 'A-Za-z\u00C0-\u00D6\u00D8-\u00F6\u00F8-\u02B8\u0300-\u0590\u0800-\u1FFF'+'\u2C00-\uFB1C\uFDFE-\uFE6F\uFEFD-\uFFFF',
        rtlChars    = '\u0591-\u07FF\uFB1D-\uFDFD\uFE70-\uFEFC',
        rtlDirCheck = new RegExp('^[^'+ltrChars+']*['+rtlChars+']');

    return rtlDirCheck.test(s);
};

One solution can be adding a toggle-rtl option some place to change the preview mode to rtl and apply the appropriate styles to the preview pane. the settings could be consistent for each note (although not necessary).

please add rtl language like persian to boostnote

[binyamin]

Would a rtl/ltr toggle suffice? @kazup01

[Flexo013]

@b3u That should be enough for a first version with RTL support. If we want a better way of detecting it in the future then we can add that at a later point.

Thanks for wanting to implement this feature!

There is also a direction library which checks a string and returns its direction based on the first (not neutral) character in the string. deciding the direction of each paragraph could be easier using this library, if dynamic changing of the direction is preferred.

Hey,

See #3282
I think that this satisfies the need for RTL support.

any ideas on improvements?

[tuxitop]

@ibraude could it be possible to add a direction: ltr and text-align: left property for the code tag that would always be LTR?

[ibraude]

@tuxitop Yeah, good catch. I added that and also an option to set up a hotkey for direction toggle
