192644 - (translate-math-start) Arabic/Hebrew (done)/Thai (done)/Chinese (done) translation of mozilla.org/projects/mathml/start.html

Status: RESOLVED FIXED

(Core :: MathML, defect)

Description

[Roland Mainz]

RFE: There should be an arabic/hebrew/thai translation of
http://www.mozilla.org/projects/mathml/start.xml

Main purpose beyond that it would be nice for Arabic/Hebrew/Thai-speaking people
is that we should investigate whether MathML and BiDi/CTL play well together -
or not (... and if there are bugs/issues we should file spin-off bugs to handle
the  problems until it works OK).

[Arthit Suriyawongkul]

ok, i will take this for Thai.

Comment 2

[Daniel Wang]

shouldn't this be a mozilla.org:webmaster bug?

Comment 4

Looking good. But a few remaining tweaks are needed:

- use encoding=UTF-8 (I have updated the main one to include the encoding and
other tweaks, see the Document History in order to sync your version:
http://www.mozilla.org/webtools/bonsai/cvslog.cgi?file=mozilla-org/html/projects/mathml/start.xml&rev=&root=/cvsroot/).

- I have added: [Languages: English - Thai] so that people can flip back and
forth between translations. In your version, simply make English active.

- When I mouse-over the links, the status bar showed characters in chinese,
let's hope that the problem will be resolved by specifically setting
encoding="UTF-8".

I don't see that in my Mozilla1.4a Solaris/SPARC build. Are you sure that...
a) ... you have Thai fonts
b) ... have a CTL-enabled build (e.g. --enable-ctl) ?

Another nit:
- The alternate stylesheets do not seem to work - trying to select "View/Use
Style/Mathematica" - no change... ;-( (yes, the CSS in demo/ is available) ...

Comment 6

[rbs]

Was testing on Win32 where there are no problems/extra-steps with Thai fonts.

Comment 7

[Arthit Suriyawongkul]

how about using Language ID instead of full language name in file name?
("start-th.xml" instead of "start-thai.xml") .. just ask for comment.

also changing from

MathML in Action
[ Languages: English - Thai ]

to

MathML in Action
[ Languages: English - ä·Â ]


so Thai speakers can understand it immediately :)

rbs:
What about making the Thai version of start.xml the "MathML sample of the week"
and anncouce it ? :)

Comment 12

[Tsahi Asher]

i'm starting to work on a hebrew translation. what is "typeset" and "displaystyle"?

i can already see problems in RTL with the determinant and the formula at
"Consider an interesting markup like this".

Comment 13

[rbs]

> "typeset" 

means formatted, represented, marked up...

> "displaystyle"

a technical term specific to math layout. It refers to to those equations that
are presented in "block" mode (to borrow the terminology of CSS). The opposite
is "inline". In inline, the text and math are mixed together on the same line.
In block (displaystyle), the math appears in isolation on its own line. (There
are subtle differences in the rndering rules. The inline is made more cramped to
minimize the disruption of the line.)

I think a translation of "block display" will be okay.

> i can already see problems in RTL

@see bug 208309

The MathML spec has no provision for BiDi/RTL. There are two approaches
currently in use for this: 

1) write the formulas from right to left, with mirrored symbols (as it is done
in Egypt and Syria)

2) write the formulas from left to right (as it is done in Morocco and Algeria),
which makes translation easier from Latin languages but involves the mixing of
directions in the same document. 

In other words:
in Egypt/Syria they do: RTL text + RTL math (with "mirrored" (flipped) symbols)
in Morocco/Algeria they do: RTL text + LTR math

What is the practice in the Hebrew language?

Mozilla does what is done in Morocco/Algeria (the MathML spec is silent on
this...). Hence leave the math intact while you are translating.

Comment 14

[Tsahi Asher]

in hebrew we use RTL for text and LTR for numbers and formulas.

some of the formulas end with a period or comma, that is placed on the right end
of the formula. in hebrew, text ends at the left end, of course, so i deleted
these and put a text (not MathML) period or comma at the end of the formula. is
that ok?

Comment 15

[rbs]

Yes, that's ok.

Comment 16

[Tsahi Asher]

Attachment: hebrew translation

here it is.
note two problems:
1. the yellow box won't zoom in/out
2. the letters in the determinant are flipped.

Comment 17

[rbs]

> 1. the yellow box won't zoom in/out
That's strange.

> 2. the letters in the determinant are flipped.
Try specifying this CSS rule (which I should probably put by default mathml.css)
math { 
  direction: ltr
}

Comment 18

[Tsahi Asher]

Attachment: hebrew translation v.2

added the proposed css, which fixed the determinant.
also fixed broken links to mozilla-banner.gif, tex.css and mathematica.css (the
last two will work when the page is put in
http://www.mozilla.org/projects/mathml/) and a missed "typeset" i didn't
translate in the last line.
i added a <div dir="ltr"> around the banner and the navigation links at the
top, i don't know if that's legal in xml.

Comment 19

[rbs]

Thanks, checked in: http://www.mozilla.org/projects/mathml/start-hebrew.xhtml

https://bugzilla.mozilla.org/show_bug.cgi?id=192644

These pages have recently been updated to fix some HTML/CSS errors. The new address is:

http://www.mozilla.org/projects/mathml/start.xhtml

The plan is to move all these pages to MDN when bug 602828 is fixed so that it will be easier to maintain them.

Even if some content of these pages may be outdated, the initial goal of this bug (testing mathematics with BiDi/CTL) is still worthwhile, in my opinion. BTW, MathML3 was released last October and adds new features for arabic mathematics that should help to overcome the limitations mentioned in comment 13.

Comment 22

[Xuan Hu]

Attachment: Chinses translation of start page. Ver. 1

hi, everyone.  

I made a Chinese version based on current start page. 
(start.xhtml, not start.xml) 
If there is anything wrong, feel free to tell me.  

Besides. There is an error in current page. 
"a x^2 + b x = c," (the corresponding equation in semantics)
the ending comma should not be included in mathml code.
It should be normal plain text.

Comment 23

[Frédéric Wang (:fredw)]

Thank you for working on this!

A few remarks:

I suspect you used Firefox to do "save as, full web page", so some of the markup has changed (the URLs etc). Can you please download the page in another way, for example with "save as, web page only"? Only modifying the relevant parts of the original page will help to better see the changes for the reviewers. In general changes are submitted via patches. Maybe you can create a diff of the original page with your translation?

https://developer.mozilla.org/En/Developer_Guide/How_to_Submit_a_Patch

+<html lang="en"><head>
+  <meta http-equiv="content-type" content="text/html; charset=UTF-8">

<html lang="en"> should be set to chinese language I think.

OK that's fine if you change this.

I suppose the "if" in one of the formula should be translated too, although that's not done in other versions of the start page.

I think we'll have to modify the "Languages" links at the top of each start page to point to the Chinese version.

Karl: do you know if we can still edit the page on mozilla.org or do we have to wait until all is moved to MDN?

Comment 24

[Xuan Hu]

Attachment: Chinese translation of start page. Ver. 2.

Thx for fredw's suggestions and reviewing.

I just submit the diff between start.html and start-zh.html.

I am still a little confused whether this patch is correct. As start-zh.html should be a complete new file, but I also want to stress on the difference between the translation and raw page as most of html and mathml code is same.

Any suggestion or criticism is welcome.

I'm guessing mozilla.org still picks up svn changes, but I don't know for certain.

Yes, best to accentuate the differences between the existing version and the new version.  Try using "svn copy start.html start-zh.html", copy your new file on top, and see whether svn diff shows differences.

This is meant to be a list of links between other translations, so start-zh.html should link to start.html and all start*.html files except start-zh.html should include a link to start-zh.html.

If Frédéric can review the rest of the patch, then I can commit to svn.

Comment 26

[Xuan Hu]

Attachment: Chinese translation of start page. Ver. 3.

Update for Chinese Translation. Thx for code review of karl and fredw.

Summary of changes:
- translate main content into Chinese
- revise the Language navigator to be consistent
- punctuation error in mathml content. 
  (The ending punctuation should not be included in the mathml scope)

Comment 27

[Frédéric Wang (:fredw)]

Just a note on moving the punctuation mark outside the <math> element: if it's a inline expression that can lead to bug 209693, if it's a display expression the punctuation mark will be displayed on a new line (which is probably not what we want). If it's semantically wrong to put it in an <mo>, maybe a <mtext> is more appropriate.

Comment 28

[Xuan Hu]

hi, fredw

Sorry for ignore the bug related to punctuation mark.
Do I need to rollback the modification about punctuation or any other suggestions for current start page?

Yes, I think it's better to rollback the modification to avoid possible bugs. If it is a problem for the Chinese version, maybe you can put the punctuation in a <mtext> instead.

Remove most of modification related to punctuation,
only one is reserved in start-zh.html due to word order changed by translation.

Review of attachment 622675 [details] [diff] [review]:
-----------------------------------------------------------------

Thank you for taking up this (and sorry for my long delay)! In general the translation looks good, but I am still giving you a bunch of inline comments below. They use the s/change-from/change-to/ notation. Some of them that are marked as (nit) are minor as compared to that ones that are not marked. But still, feel free to reject any comment as I am not an authoritative reviewer in any way and also that I am a native speaker of Traditional Chinese and I am often criticized by my friends in QQ channels for not using the right words. 

Karl, could you please commit this to svn as long as Xuan sends the next patch? (Or if he doesn't update the patch within a week.)

s/displaytable/displaystyle/

Pardon my ignorance about mathematical typesetting, it seems that this is a jargon originating from LaTex. Which is the correct way to refer to it, "displaystyle" or "display style"?

Anyway, the translation is pretty good in that it resolves this confusing part.

Yes display style is just a specific way to draw the formula without trying to limit its vertical height (some symbols like sums and integral are large, indices are placed above and below such symbols instead as sup/subscripts, etc). I think both forms "displaystyle" and "display style" are correct. We also sometimes use "display mode".

I'm not sure what the author means with this WYSIWYG discussion. I think the paragraph is about expressiveness of MathML. Here the example shows that we can force parentheses to have a minimum size and to stretch in symmetric way.

(Note: these pages will move to MDN when bug 665732 is fixed, so I think we don't have to worry too much for now, people will probably improve the wording later)

hi, kennyluck

Thx for you detailed suggestion, they are really helpful. I follow most of your advice except for minor change. An important one is about the 'accent equation', after discussing with some friends, I think '变音符号' will be more suitable as ‘附加符号’ is too general.

If there needs some more revise, feel free to tell me.

Thank you very much, Rami. Can you explain why you added

+math { 
+  direction: ltr;
+  unicode-bidi: embed;
+}

Note that attaching dir="rtl" on a <math> element gives the style "direction: rtl;".

It seems that some operators are not mirrored, like slash, floor and ceiling brackets. Can you confirm it and tell me if you see more? I think it's a bug in the MathML rendering code that could easily be fixed.

Also, can you please modify the other start pages (English, Thai, Hebrew and Chinese) to add a link pointing to the new start-ar.html?

I believe this should be "direction: rtl;". Unlike hebrew, Arabic letters are used for varaibales in mathematical equation, and the direction is therefore from right to left.

As I said in comment 4, <math dir="rtl"> is already styled with "direction: rtl;", so we don't need to set it again. As for unicode-bidi, IIUC it is only needed with mixed ltr/rtl content:

https://developer.mozilla.org/en/CSS/unicode-bidi

but here both text and equations are RTL, so I don't think it is needed either.

However, that makes me think of the question (bug 208309 comment 59) about how inline RTL math should behave in LTR math like in Persian or Moroccan style. Should we styled <math dir="rtl"> with "unicode-bidi: embed;" by default? Or use another unicode-bidi value?

Frédéric:

The translation is good.

For the case you described, I think <math dir="rtl"> with "unicode-bidi: embed;" would suffice.

Bug 757125 should allow to mirror more operators in RTL mode, including fences like floor/ceiling brackets. As for the four <mo> with slashes, if as I suspect they have to be mirrored too, then the appropriate character to use seems to be

Unicode Character 'DIVISION SLASH' (U+2215)

I just move the MathML start page and the translations to MDN:
