Description Fridolin Somers 2012-10-18 10:41:25 UTC
In french translation of calendar.inc :
Because (line 31) :
    currentText: _('Today'),
is translated
    currentText: _('Aujourd'hui'),
additionnal quote brakes the Javascript.

This provokes the use of american format dates in calendar pop-up.

I had a discussion on translate list, the way chosen to repair it is to use HTML escape char sequence "'" instead of single quote in translated strings.
Same thing for double quotes, &, < and >.

So I will correct on translate site but one can follow the resolution on this bug.

Comment 3 Fridolin Somers 2012-10-18 12:21:55 UTC
Is there not a risk to convert quotes with the fact that TT elements are translated (they are %s) ?

I don't think so. This patch transform only strings coming from JS. I've done a grep -R "&apos" and "&quot" in fr-FR opac & staff templates directory, and I didn't find anything wrong. You can check yourself after applying this patch, and regenerating localized templates.
Comment 5 Kyle M Hall 2012-10-19 12:16:03 UTC
This patch isn't working for me. If I set my language to fr-FR, I still get my dates in MM/DD/YYYY no matter what setting I have for dateformat.
Comment 6 Kyle M Hall 2012-10-19 12:19:09 UTC
Cancel that. I'm stupid ; )

I wasn't thinking about the fact that this is a modification to the translation generator, and that I needed to regenerate my French translations before testing!

Comment 8 Katrin Fischer 2012-10-19 12:46:07 UTC
Hi Kyle,

as I said on the mailing list, I am a bit worried the script might translate ' that shoudl not be replaced. Did you check the updated po files for differences? I think maybe we could start comparing a po file with not so many ' (not French ;) ) before and after the patch to find strings where this might be causing problems. I am thinking about program code that shows up in the po files by mistake.

Well, indeed, you're right to be worried. Replacing simple quote (')
with &apos; seems not to work so well. It seems to be displayed has it
is: the code &apos; not the '.  I don't understand how it worked for
Fridolyn. But the issue is here. And not only in calendar, also in
biblio records merging. I will propose another patch with a test plan.
Katrin, the patch doesn't touch the .po file. It modifies spefically how
the JavaScript translated strings is sent back for inclusion in
templates.

> is: the code &apos; not the '.  I don't understand how it worked for Fridolyn.

I modified PO files to use &apos; in translated strings :
msgid:"Today"
msgid:"Aujourd&apos;hui"

I will correct it french POs but I encourage you to work on this bugfix.

Comment 14 Marcel de Rooy 2012-11-07 14:33:28 UTC
QA Comment:
Single quote seems to work (but see note below). Double quote does not work.

If I translate:
msgid "Your lists:"
msgstr "Uw "lijsten:"

It results in: 
param1 += "<optgroup label=\""+_("Uw \"lijsten:")+"\">";[% FOREACH addbarshelvesloo IN addbarshelvesloop %]
(Example from opac-results.tt within document ready function section. )

OPAC displays only the word Uw. But does not show \"lijsten.

NOTE:
If I would use already a backslash to escape my quotes in the PO file like this:
msgstr "Uw \'lijsten:"

I would not like to see the backslash in the display.
In other words: Could you improve the regex with lookbehind to prevent adding a backslash that is already there?

Changing status to reflect need for attention.

Hi Marcel,
To me, your example is not good.
You cannot translate "Your lists:" into "Uw "lijsten:", the po file become wrongly formatted.
Have you an example with a correctly formatted po file ?
Comment 16 Fridolin Somers 2012-11-29 09:10:52 UTC
After reflexion, I think it is no good idea to have an automatic quote escape.

For example, if you have a single quote in a double quote string (or opposite) : 
_("Aujourd'hui") will become _("Aujourd\'hui"), the backslash will be displayed.

Also, like Marcel example, there might be problems with HTML added in JS.
For example : 
  $("#id").html("<span title=\"" + _("Dangerous") + "\" />")
will generate
  <span title="Dangerous" />
In this case, the translation must not contain a double quotes, even escaped: 
  $("#id").html("<span title=\"" + _("\"Danger\"") + "\" />")
will generate
  <span title=""Danger"" />, bad HTML.

I've looked at http://wiki.koha-community.org/wiki/Coding_Guidelines.
In JavaScript section, double quotes are always used : _("xxx").
Looking at code, double quotes are used 2629 time and single quotes only 143 times.

So if we always use double quotes, single quotes are not a problem anymore and it was the main problem (it is often used in French).
I've looked at French PO, double quotes are actually never used in JavaScript translation ; it can be managed one by one.

I've looked at old version of calendar, it used double quotes, that's why there was no problem with Today => Aujourd'hui.

I will propose a patch for that.

Comment 20 Marcel de Rooy 2012-12-06 11:58:09 UTC
Frederic,
How do you feel about Fridolyn's counterpatches ? 

Just an additional thought: If we resolve all quotes now, how do we prevent them being added again the wrong way in the future? Unit test?

Hi Marcel,
If this rule is accepted, it would be possible to add a regexp in our qa tools in order to catch all simple-quoted strings added in the js files.

That would be good. But an automated test would still be safe too..
Comment 23 Katrin Fischer 2012-12-10 09:56:22 UTC
I think an automated test would be preferrable, or have both.
Comment 24 Chris Cormack 2012-12-10 21:41:09 UTC
I agree +1 for a test.

Can someone help me on that? I have no idea how it works.

My patches seems to be acceptable, so I change status to needs signoff.

Hi Chris,

Don't you think is better to push the complete filepath in order to avoid ambiguity between OPAC and intranet files?

-        push @files, { name => "$_", lines => \@lines } if @lines;
+        push @files, { name => $File::Find::name, lines => \@lines } if @lines;

Yep I do .. did you notice that now there is a review link next to each patch, I added that last weekend, you can now do inline code comments :)
I hope that will be useful for doing qa.

Do you want me to resubmit? Im happy if you just fix that line on signing off.

I will fix it but I wanted to have your permission first.


The proposed patch for Bug 9555 fixes this test.

Note that a test in koha-qa has been introduced and detect simple-quote strings.

Marked as Passed QA.
