TeXstudio uses .cwl files for storing information about which macros are defined by which packages, one file per package. This information is used for autocompletion suggestions and highlighting of unrecognized macros. Most of these files I can find in C:\Users\doncherry\AppData\Roaming\texstudio.
For some packages, e.g. hyperref and xspace, however, I can’t find them in that directory and neither in the program’s directory C:\Program Files (x86)\TeXstudio. Where are they hiding? Are they hard-coded into the executables?
\xspaceaddexceptionsto it. For just looking at them, http://svn.code.sf.net/p/texstudio/code/trunk/completion/ contains all the predefined .cwl files, I would hypothesize. – doncherry Apr 24 '13 at 19:25\xspaceaddexceptionsto your own costom.cwlfile. – Qrrbrbirlbel Apr 24 '13 at 19:42:). – doncherry Apr 24 '13 at 19:43.exe. Proposal: Copy bothxspace.cwlandhyperref.cwlto the%APPDATA%\texstudio\folder and add the missing macros. – Qrrbrbirlbel Apr 24 '13 at 19:55
