Hi<br><br>there is a project for i18n on sourceforge. It contains for example bindings to the gettext library which could be helpful. I'm not sure though how up to date this project is (project page looks very empty).<br>The code is still available in the sourceforge cvs repository:

What methods and tools are there for i18n of Haskell programs?<br><br>(I.e. I want output in several languages,<br>with the language configurable at runtime,<br>and I want to add languages without recompilation.)<br><br>
a typical source text (for my application) is here
<br><a href="http://141.57.11.163/cgi-bin/cvsweb/tool/src/Graph/Circle/Plain.hs?rev=1.2" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://141.57.11.163/cgi-bin/cvsweb/tool/src/Graph/Circle/Plain.hs?rev=1.2
</a><br>it contains (German) text strings all over the place.
<br><br>In Java/Eclipse, I would "Source -> Externalize Strings"<br>and this replaces each string by something like<br>Messages.getString("Foobar.0") where Messages is a global variable<br>(constructed at program start from reading a properties file)
<br><br>In Haskell, I see at least two problems:<br>a) reading the file is in IO<br>b) there are no "global variables". implicit parameters perhaps?<br>c) when I'm trying to be clever, I use "deriving Show/Read" or similar.
<br>then i18n should rename the constructors/accessors? I rather not.<br><a href="http://141.57.11.163/cgi-bin/cvsweb/tool/src/Grammatik/Type.hs.drift?rev=1.6" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">
