In gvim the command
:browse confirm e launches a GTK file browser. The default file mask in this window depends on the filetype from which the browse window is invoked. I would like to change that default file mask depending on the filetype. For example from
.cpp file the mask is
*.cpp *.c++ and I want to add
*.hpp *.ipp there. From python file the mask is
*.py I would like it to be
*. And so on.
I use gvim version 8.1.141 on linux devuan beowulf.
(I could not find proper tags for this question, I tried to use tags: file browser, gtk, wildcard, glob, mask)
So far by grepping gvim sources I have found:
grep -E "\*\.cpp \*\.c++" . -r --color ./runtime/ftplugin/pyrex.vim: \ "C++ Source Files (*.cpp *.c++)\t*.cpp;*.c++\n" . ./runtime/ftplugin/c.vim: let b:browsefilter = "C++ Source Files (*.cpp *.c++)\t*.cpp;*.c++\n" . ./runtime/ftplugin/c.vim: \ "C++ Source Files (*.cpp *.c++)\t*.cpp;*.c++\n" .
So what is
b:browsefilter and how to use it?
:h browsefilter says that "You can override the filter setting on a per-buffer basis by setting the b:browsefilter variable.".
But I want to override it not per-buffer, but per-filetype from where the browse dialog was invoked.
