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
For some packages, e.g.
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?
