A simple tool that I initially put together in day and a half (but the
features grew). It's purpose is simply to search and check various environment
variables for missing directories. And check where a specific file (or wildcard)
is in a corresponding environment variable. The %PATH%, %INCLUDE%,
%C_INCLUDE_PATH%, %CPLUS_INCLUDE_PATH%, %LIBRARY_PATH%, %LIB% and/or
%PYTHONPATH% variables are checked.
The option --path also checks these registry keys:
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths and
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths
and enumerates all keys for possible programs. E.g. if registry contains this:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\makensis.exe =
f:\MinGW32\bin\MingW-studio\makensis.exe,
envtool --path maken* will include f:\MinGW32\bin\MingW-studio\makensis.exe
in the result.
Problem with old programs pestering your PATH and Registry entries can be tricky
to diagnose. Here I had an problem with an old version of the "FoxitReader PDF reader":
Checking with envtool --path foxit.exe*, resulted in:
Matches in HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths:
(2) 27 Nov 2014 - 10:24:04: f:\ProgramFiler\FoxitReader\FoxitReader.exe
Matches in %PATH:
21 Apr 2006 - 17:43:10: f:\util\FoxitReader.exe
(2): found in "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths".
Hence if you write FoxitReader in the Window Run-box (Winkey-R), you'll get the
newer (27 Nov 2014) FoxitReader launched. But if you say FoxitReader in your shell
(cmd etc.), you'll get the old version (21 Apr 2006).
Other examples:
E.g. 1: envtool --path notepad.exe* first checks the %PATH% env-var
for consistency (reports missing directories in %PATH%) and prints
all the locations of notepad.exe*. On my box the result is:
Thu Jul 21 16:02:20 2011 : f:\windows\system32\notepad-orig.exe
Mon Nov 18 19:26:40 2002 : f:\windows\system32\notepad.exe
Thu Jul 21 16:13:11 2011 : f:\windows\system32\notepad2.exe
Mon Nov 18 19:26:40 2002 : f:\windows\notepad.exe
E.g. 2: envtool --inc afxwin* first checks the %INCLUDE% env-var
for consistency (reports missing directories in %INCLUDE) and prints
all the locations of afxwin*. On my box the result is:
Thu Apr 14 18:54:46 2005 : g:\vc_2010\VC\AtlMfc\include\AFXWIN.H
Thu Apr 14 18:54:46 2005 : g:\vc_2010\VC\AtlMfc\include\AFXWIN1.INL
Thu Apr 14 18:54:46 2005 : g:\vc_2010\VC\AtlMfc\include\AFXWIN2.INL
Thu Apr 14 18:54:46 2005 : g:\vc_2010\VC\AtlMfc\include\AFXWIN.H
Thu Apr 14 18:54:46 2005 : g:\vc_2010\VC\AtlMfc\include\AFXWIN1.INL
Thu Apr 14 18:54:46 2005 : g:\vc_2010\VC\AtlMfc\include\AFXWIN2.INL
E.g. 3: If an App Paths registry key has an alias for a command, the target
program is printed. E.g. if:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\winzip.exe
points to c:\PROGRA~1\WINZIP\winzip32.exe
(here winzip.exe is an alias for the real program winzip32.exe). Hence
envtool --path winzip* reports:
Fri Oct 11 09:10:00 2002: G:\PROGRA~1\WINZIP\winzip.exe !
Fri Oct 11 09:10:00 2002: G:\PROGRA~1\WINZIP\winzip32.exe !
(!) - found in registry.
E.g. 4: It's pretty amazing what the FindFile() API in Windows can do. E.g.: *envtool --path -?++.exe
Tue Nov 19 12:01:38 2002 : g:\Mingw32\bin\mingw32-c++.exe
Tue Nov 19 12:01:38 2002 : g:\Mingw32\bin\mingw32-g++.exe
Wed Mar 09 14:39:05 2011 : g:\CygWin\bin\i686-pc-cygwin-c++.exe
Wed Mar 09 14:39:05 2011 : g:\CygWin\bin\i686-pc-cygwin-g++.exe
E.g. 5: If you have Python installed, the --python option will search in
%PYTHONPATH and sys.path[] for a match. E.g.:
envtool.exe --python ss.py*
24 Jun 2011 - 11:38:10: f:\ProgramFiler\Python27\lib\ssl.py
16 Feb 2011 - 12:14:28: f:\ProgramFiler\Python27\lib\site-packages\win32\lib\sspi.py
16 Feb 2011 - 12:14:28: f:\ProgramFiler\Python27\lib\site-packages\win32\lib\sspicon.py
E.g. 6: The --python option wil also look inside Python EGGs (plain ZIP-files) found
in sys.path[]. E.g.:
envtool.exe --python socket.py
27 Mar 2013 - 16:41:58: stem\socket.py (%PYTHONHOME\lib\site-packages\stem-1.0.1-py2.7.egg)
30 Apr 2014 - 09:54:04: f:\Programfiler\Python27\lib\socket.py
C-source included in ./src. Makefiles for MingW, Cygwin, Watcom and MSVC. Use at own risk. Enjoy!

0.1: Initial version.
0.2: Added file date/time stamp. Check for suffix or trailing
wildcard in file-specification. If not found add a trailing "*".
0.3: Handled the case where an env-var contains the current directory.
E.g. when "PATH=./;c:\util", turn the "./" into CWD (using 'getcwd()')
for 'stat("/.")' to work. Turn off command-line globbing in MingW
('_CRT_glob = 0').
0.4: Rudimentary check for Python 'sys.path' searching.
0.5: Add a directory search spec mode ("--dir foo*.bar" searches for
directories only). Better handling of file-specs with a sub-directory
part. E.g. "envtool --python win32\Demos\Net*".
0.6: Add support for POSIX-style file matching (using fnmatch() from djgpp).
E.g. a file-spec can contain things like "foo/[a-d]bar".
Note: it doesn't handle ranges on directories. Only ranges on directories
withing Pyhon EGG-files are handled.
Improved Python 'sys.path' searching. Uses zipinfo.exe and looks inside
Python EGG-files (zip files) for a match.
0.7: Improved Python 'sys.path' searching. Look inside Python EGGs and ZIP-files
for a match (this uses the zipinfo external program).
Add colour-output option '-C'.
0.8: New option '--pe' outputs version info from resource-section. E.g.:
envtool --path --pe -C vcbuild.*
Matches in %PATH:
19 Mar 2010 - 15:02:22: g:\vc_2010\VC\vcpackages\vcbuild.dll
ver 10.0.30319.1
0.9: Cosmetic changes in debug-output ('-d') and command-line parsing.
0.92: Added option "--evry" to check matches in Everything's database.
This option queries the database via IPC.
Ref. http://www.voidtools.com/support/everything/
0.93: The "--python" option now loads Python dynamically (pythonXX.dll)
and calls 'PyRun_SimpleString()' to execute Python programs.
0.94: Fixes for '--evry' (EverThing database) searches.
Drop '-i' option.
Add '-r' option.
0.95: Tweaks for better 'fnmatch()' matches.
Improved '--evry' Regular Expression (--regex) searches.
Build the MSVC-version using '-MT' (drop the dependency on MSVC1*.DLL)
0.96: Better Python embedding; lookup python.exe in env-var %PYTHON, then on
%PATH. Test for correct Python DLL. Report full name of python.exe in
"envtool -V".
