[cfe-dev] tabs in the input and their effect on the column position

[Dimitri van Heesch]

Hi All,

I'm currently experimenting with improving doxygen's parsing capabilities by using the information from clang. 
I'm using the libclang functions clang_tokenize and clang_annotateTokens to create hyperlinked and syntax highlighted 
output for the source files processed by doxygen.

So far it works quite well, but when the source file contains a tab character this seems to be counted as one character, causing
the output to be misaligned.

Is there some way to configure the number of spaces in a tab? or is there a way to replace tabs by spaces before sending the
contents of a file to libclang, without first having to write the detabbed file to disk?

Any help is appreciated.

Regards,
  Dimitri
