Hi Brian,
I appreciate your clarifications. I am sending this reply to the
R-devel, as per you suggestion.
As mentioned in my post, I have no prior experience with this R function
and logically, I looked up its help page, which states:
Conventionally the domain for *R* warning/error messages in package
pkg is |"R-pkg"|, and that for C-level messages is |"pkg"|.
While it certainly mentions messages in the C-realm, it does not state
that they cannot be translated using gettext(). This is less than
obvious and could perhaps be explicitly stated.
You are asking us to state what *can not* be done? It does clearly
state the the domain for *R* messages in a package is "R-pkg". Domain
"R" is not of that form.
If gettext() cannot be used to get the translation for the "Error in "
message in some supported language, then is there an alternative?
You put it in a domain named "R-pkg", prepared using xgetttext().
Best,
Florent

The 'wierdness' is that 'R' is a domain of C messages and you are
trying to use it from R. How messages are massaged before being sent
for translation depends on the language, including how trailing spaces
are handled. There is no reason to expect domains intended for C
code to work in R-level gettext(), nor in stop() etc.
This was really an R-devel question: see the posting guide.

Hi,
I am trying to use the gettext() function to translate some text. I
have never used this function before, so, it's entirely possible that
I am doing something wrong. The issue that I am encountering is that
gettext() properly translates some text, but not some other.
Natural language was compiled in my R (installed from the Debian
repositories):
$ R
R version 2.15.1 (2012-06-22) -- "Roasted Marshmallows"
[...]
Natural language support but running in an English locale
[...]
q()
Here is some text that has some translation in the file ./po/fr.po:
#: src/main/errors.c:290
msgid "invalid option \"warning.expression\""
msgstr "option incorrecte \"warning.expression\""
[...]
#: src/main/errors.c:582
msgid "Error in "
msgstr "Erreur dans "
Start R in French and see if I can get something translated to French:
$ LANG=fr_FR.UTF8 R
stop('This is an error')
Erreur : This is an error
bindtextdomain("R") # does not seem necessary, but just to be safe...
[1] "/usr/share/R/share/locale"
gettext("Error in ", domain="R")
[1] "Error in "
"invalid option \"warning.expression\"" -> msg; gettext(msg,
domain="R")
[1] "option incorrecte \"warning.expression\""
So, the stop() function successfully translates. I can also manually
translate some entries, but why can does it not work for
gettext("Error in ", domain="R")?
Any idea?
Thanks
Florent
