Re: checking mainlanguage setup

Re: checking mainlanguage setup

[Jeong Dalyoung]

Dear Pontus, Marco, and Peter,

Thank you for replies.

I tested the following codes:

1)
\startluacode
if languages.current() == "kr" then
context("Korean")
else
context("Not Korean")
end
\stopluacode

2)
\doifelse\currentlanguage{en}{\def\lang{English}}{\def\lang{Not English}}\par
currentlanguage: \lang

are working well. 

But, the code

\startluacode
if languages.current() == "kr" then
context([[\def\lang{Korean}]]) %("\def\lang{Korean}")
else
context([[\def\lang{English}]]) %("\def\lang{Korean}")
end
\stopluacode

currentlanguage: \lang

is not working. (undifined control sequence error)

I think that there is a simple way to use lua code for this which I don't know. I have to read CLD manual.

Thanks again.

Best regards,

Dalyoung

(Untested) try

context.setvalue("lang", "English")

or

context([[\\def\\lang{English}]])

You are right. [[\def\\Lang{English}]] method works.

I summerize it as a test file. The first 5 methods are working well, but the last one using \noexpand cause the error.

Thank you.

What exactly do you plan to do with the language check, for simple texts your method is overkill and labeltexts are better suited, even a command which prints a text can be written in TeX without problems:

\def\LangOne
  {\doifelse{\currentmainlanguage}{en}
     {English 1}
     {\doifelse{\currentmainlanguage}{nl}
        {Dutch 1}
        {Unknown 1}}}

\def\LangTwo
  {\processaction
     [\currentmainlanguage]
     [     en=>English 2,
	       nl=>Dutch 2,
      unknown=>Unknown 2]}

\setuplabeltext[en][langthree=English 3]
\setuplabeltext[nl][langthree=Dutch 3]
\setuplabeltext    [langthree=Unknown 3]

\starttext

\LangOne:\LangTwo:\labeltext{langthree}:\translate[en=English 4,nl=Dutch 4]

\mainlanguage[nl]

\LangOne:\LangTwo:\labeltext{langthree}:\translate[en=English 4,nl=Dutch 4]

\mainlanguage[fr]

\LangOne:\LangTwo:\labeltext{langthree}:\translate[en=English 4,nl=Dutch 4]

\stoptext

No errors message, but it's not working as the way as  I want. It just print "def langEnglish".

This cause the error message and halt the compiling.

context([[\def\noexpand\Lang{...}]])

or

context([[\def\string\Lang{...}]])

I don't understand why

context([[\def\\Lang{...}]])

does not work. I thought that when TeX code is exapnded inside lua 
environment \\ was equal to \string\.

Aditya

PS: \lang macro is defined by bib module.

It is not working. It prints "def lang English".

OK.

I meant just the way how strings in Lua are entered

- if inside quotation marks, escaping is required, thus "\\" yields to backslash,
- if inside [[ ... ]], single \ gives backslash, and of course \\ gives TWO backslashes.

I guessed that your original

[[\\def\\lang{English}]]

could have caused the problem, so I corrected it to

[[\def\lang{English}]]

Cheers,

Lukas

[[ ]] vs " " is a lua thing ... but when you pass things from within 
tex, expansions happens the same in both; you can try

context("\detokenize{...}")

Sorry, that should have been

\ctxlua{"\detokenize{...}"}

which takes care of things at the tex end. When at the lua end, you need 
to use \\ (or indeed [[with regular \'s]].

Anyhow, it does not hurt to always to take good look at \'s because 
commands might end up in cycles (or for instance can end up in auxiliary 
files). This is why many commands are defined using \unexpanded.  Even 
if you pass something using context at the lua end. You can see what 
gets passed to tex using:

\enabletrackers[context.trace]

What you see there should look like regular context.

(btw, context.setvalue{"Lang","English") also works well and has no 
backslashes)

Hans

Re: checking mainlanguage setup

Dear Aditya,

Here are the test result.

It is working.

>

> context([[\\def\\lang{English}]])

It is not working. It just prints "def langEnglish".

Now, I got two solutions, using luacode and using \doifelse.

Thank you.

Best regards,

Dalyoung

BTW, are not there too many backslashes?

Shouldn't it be (untested):

context("\\def\\lang{English}")

or

context([[\def\lang{English}]])

checking mainlanguage setup

[Jeong Dalyoung]

Dear all,

Is it possible to check what is the mainlanguage set in document?
Now, I use \enablemode[kr] to do something A. But, I'd like to do it automatically if possible.

For example,

I'd like to do the following type of setup.


if mainlanguage == kr then

	do something A

elseif mainlanguage == en then

	do something B

else
	do something C

endif

So, if \mainlanguage[kr] is set, then do A, and etc.

Thank you for reading.

Best regards,

Dalyoung

According to http://wiki.contextgarden.net/Modes#System_modes , 
the mode **kr should be automatically set if kr is the main language
(I haven't tried it, though).

    context("Something A")

     context("Something B")

     context("Something C")

Yes. Example:

%\mainlanguage[fr]
%\language[fr]
\starttext
currentlanguage:
\doifelse\currentlanguage{fr}{French}{Not French}\par
currentmainlanguage:
\doifelse\currentmainlanguage{fr}{French}{Not French}\par
translate: \translate[fr=Français, en=French]
\stoptext
