case-sensitize filename

case-sensitize filename

[lode leroy]

Hello,

I would like to know if there is an easy way to convert a file path
that has been converted to all-lowercase back to the properly cased version?

I have the following usecase:

cl /c C:\Projects\MyProject\MyProgramFile.cpp
c:\projects\myproject\myprogramfile.cpp(42): error C1234: 'CMyClass': undeclared

next-error -> c:\projects\myproject\myprogramfile.cpp

now next-error opens the correct file, but with the wrong buffer name ...
I'd like to compensate for that...

next-error -> C:\Projects\MyProject\src\MyProgramFile.cpp


Actually, the build files copy everything into "build" first, 
and emacs should open the file in "src", but I already got some elisp to take care of that...

cl /c C:\Projects\MyProject\build\MyProgramFile.cpp
c:\projects\myproject\build\myprogramfile.cpp(42): error C1234: 'CMyClass': undeclared

next-error -> C:\Projects\MyProject\src\MyProgramFile.cpp

Looks like a bug somewhere. What version of Emacs are you using?

(GNU Emacs 23.0.60.1 (i386-mingw-nt5.1.2600) of 2008-08-29 on LENNART-69DE564)

Well, for me, its a bug in vc90 (aka MS VisualC++ Express 2008)
which is reporting the error as being in file tolower(filename) rather then filename.

in the mean time, I found out that the following does what I want:

(defun filepath-transform-build-to-src (filepath)
  (progn
    (setq result (replace-regexp-in-string "\\\\build\\\\" "\\\\src\\\\" result))
    (setq result (expand-file-name result))
    (setq result (convert-standard-filename result))
    (setq result (file-truename result))
    result
    )
  )

(setq compilation-parse-errors-filename-function 
	     'filepath-transform-build-to-src)
