vim - How to enable Python support in gVim on Windows?

Question

I'm trying to get Python support in gVim on Windows. Is there a way to accomplish that?

I'm using:

• Windows XP SP3
• gVim v. 7.3
• Python 2.7.13 (ActivePython through Windows Installer binaries)

Answer 1

I had the same issue, but on Windows 7, and a restart didn't fix it.

I already had gVim 7.3 installed. At the time of writing the current Python version was 3.3, so I installed that. But :has ("python") and :has ("python3") still returned 0.

After much trial and error, I determined that:

• If gVim is 32-bit, and it usually is even on 64-bit Windows (you can confirm using the :version command), then you need the 32-bit python installation as well
• No restart of Windows 7 is required
• The version of python needs to match the version that gVim is compiled for as it looks for a specific DLL name. You can work this out from the :version command in gVim, which gives something like:

Compilation: cl -c /W3 /nologo -I. -Iproto -DHAVE_PATHDEF -DWIN32
-DFEAT_CSCOPE -DFEAT_ NETBEANS_INTG -DFEAT_XPM_W32 -DWINVER=0x0400 -D_WIN32_WINNT=0x0400 /Fo.ObjGOLYHTR/ / Ox /GL -DNDEBUG /Zl /MT -DFEAT_OLE -DFEAT_MBYTE_IME -DDYNAMIC_IME -DFEAT_GUI_W32 -DDYNAMI C_ICONV -DDYNAMIC_GETTEXT -DFEAT_TCL -DDYNAMIC_TCL -DDYNAMIC_TCL_DLL="tcl83.dll" -DDYNAM IC_TCL_VER="8.3" -DFEAT_PYTHON -DDYNAMIC_PYTHON -DDYNAMIC_PYTHON_DLL="python27.dll" -D FEAT_PYTHON3 -DDYNAMIC_PYTHON3 -DDYNAMIC_PYTHON3_DLL="python31.dll" -DFEAT_PERL -DDYNAMI C_PERL -DDYNAMIC_PERL_DLL="perl512.dll" -DFEAT_RUBY -DDYNAMIC_RUBY -DDYNAMIC_RUBY_VER=19 1 -DDYNAMIC_RUBY_DLL="msvcrt-ruby191.dll" -DFEAT_BIG /Fd.ObjGOLYHTR/ /Zi

So the above told me that I don't actually want python 3.3, I need 3.1 (or 2.7). After installing python 3.1, :has ("python") still returns 0, but :has ("python3") now returns 1. That should mean that python based scripts will now work!

I imagine future versions of gVim may be compiled against other versions of python, but using this method should let you work out which version is required.
