At (3), we are doing:

and the problem here is that the lyx string is:
Thanks for the diagnosis.
The problem turns out to be simple. In ApplyParams(), in
FindAndReplace.cpp, we apply the document params to the find and replace
buffers.
the sole reason we do that, is that we need to copy the language
settings of the main document, in order to avoid that what we search &
replace is detected as with the wrong language, w.r.t. what is typed
within (there was a trac entry about that problem, too).
Alternative solutions that were proposed included disabling at all the
language highlighting and spellchecker in the F&R workareas (but after
all I find them useful, i.e., when I search for something, the
spellchecker can highlight that I typed a "typo", so it wouldn't be
found, or it would be replaced causing problems etc.), but in the end I
had found that "ugly" way of solving the issue in FindAndReplace.cpp:
/// Apply to buf the parameters supplied through bp
static void ApplyParams(Buffer &buf, BufferParams const & bp) {
ostringstream ss;
ss << "\\begin_header\n";
bp.writeFile(ss);
ss << "\\end_header\n";
istringstream iss(ss.str());
Lexer lex;
lex.setStream(iss);
int unknown_tokens = buf.readHeader(lex);
LASSERT(unknown_tokens == 0, /* */);
}
Probably we would need a BufferParams::setLanguage() method to use,
here, instead of copying the whole parameters. Looking at
BufferParams::readLanguage(), I would implement it as:
bool BufferParams::setLanguage(std::string const &lang)
{
Language const *new_language = languages.getLanguage(lang);
if (!new_language) {
// Language lang was not found
return false;
}
language = new_language;
return true;
}
Would you like such a solution ?
