[Caml-list] postscript, printf module and coma separator.

[Caml-list] postscript, printf module and coma separator.

[Sven LUTHER]

Hello, ...

I am playing with the postscript.ml module from Nicolas Georges.

Unfortunately, i have the LANG variable set to fr_FR, and as thus fprintf
outputs floats as :

3,14

but this is not a valid postscript coordinate. 

removing the LANG variable give me the standard 3.14 output, which is
acceptable to generate postscript files.

Is there a way to have printf output floats in the standard C "." format,
independent of locales ?

Or is the best guess as how to solve this to backup, change to "" and then set
again the LANG variable using the appropriate ocaml functions ?

Friendly,

Svne Luther

That seems strange. I have also LANG and LC_CTYPE set to fr_FR, and I do
not have the problem. And that under Linux (GNU libc) and Solaris. There is
the problem with LablGtk, because GMain.Main.init sets the locale (if you
use the toplevel, you can not even enter a new non-integer float, since the
ascii -> number fails on the `.'). So I think the bug is inside LablGtk,
and should be corrected there (maybe an optional parameter to change the
environment variable before gtk_set_locale).

Yes this is also the case, just tried it in a toplevel here.

Let's move this thread to the lablgtk list if needed.

mmm, yes, that's a good idea, but still, you have to do it from the shell.

What i wanted is to do it from the ocaml program i am running though, so that
it will work whatever the environement, but then maybe a specialized printf
function could be done, don't know.

>From the book I have in front of me (which may not be accurate), it
should be possible to set the formatting of numeric types independently
of the other locale settings:

setenv LANG <Locale1>
setenv LC_NUMERIC <Locale2>

It also says that ISO C specifies a "C" Locale, which behaves the same
as uninternationalised C functions.  So it *should* be possible to use:

setenv LANG fr_FR
setenv LC_NUMERIC C

I have no idea whether this works in practice.

Hello, ...

I am playing with the postscript.ml module from Nicolas Georges.

Unfortunately, i have the LANG variable set to fr_FR, and as thus
fprintf
outputs floats as :

3,14

but this is not a valid postscript coordinate. 

removing the LANG variable give me the standard 3.14 output, which is
acceptable to generate postscript files.

Is there a way to have printf output floats in the standard C "."
format,
independent of locales ?

Or is the best guess as how to solve this to backup, change to "" and
then set
again the LANG variable using the appropriate ocaml functions ?
