Hi! Yesterday I played a bit with emacs' muse mode which has option to 'publish' to ConTeXt, but its output was wailing when texeexec-ing due to use of \textunderscore (option in muse). Today I discussed the issue on muse mailing list, got help and the following remark: '...Context gurus don't seem to imagine you can use "_" elsewhere than in math mode btw'. I looked at ConTeXt docs (excursion and manual), as well as wiki on contextgarden, but was not able to find more about what is the status of underscore '_' char in ConTeXt and is the above remark true? My usage of '_' in muse document was for preparing tables of some library functions and, as it is often the case in software, there is usually some prefix for all library functions as eg. gtk_xxxxx for GTK+ toolkit. Sincerely, Gour

Why does \textunderscore wail? \textunderscore should work fine.

:) This is how it is done in plain TeX, and both LaTeX and ConTeXt follow this. If you do not use maths at all, you can say \catcode`\_ = 11 on the top of your file and then _ will be a letter in both text and math mode (which basically means that you will have to use \sb to get subscript in math mode. It is possible to define something along the lines of underscore.sty in latex, so that _ is treated as a letter in text mode, and as a subscript indicator in math mode, but, read below.

Shouldn't such function names be written as \type{gtk_xxxx} when muse converts the document to ConTeXt? In that case the _ will be preserved. Aditya

Hmm, not ideal...

I do not remember having ever problem with underscore in LaTeX.

Right. They will fix default in muse and use \type{_} as value for underscore. Thank you for your input. Sincerely, Gour

This is just a mistake of the parser. Either _ should be translated to "\textunderscore "(\textunderscore followed by a space) or more precisely by \textunderscore{} or \_ .

Read the documentation of underscore.sty and you will know the trouble of using underscore in LaTeX (some of those are true for ConTeXt also).

No, the default should either be \_ or \letterunderscore{} (with the brackets). \type{_} will be influenced by \setuptype (or \setuptyping) and can give colored output also. Aditya

Hey, somehow never noticed this one before. Aditya

[...] As far as I can see, \nonknuthmode_ or \nonknuthmode{_} produces a wider "_" than \textunderscore{} does. -- Jean
