Until recently, the GUI used a "dumb" terminal for external commands.
With patch 8.0.1616 it is now possible to run an external command inside
the GUI window. Try it out with:
:set go+=!
:!cat testdir/color_ramp.txt
Without adding "!" to 'guioptions' it doesn't work at all. On Unix the
output looks correct.
You can even run Vim inside gvim (not that this is useful :-).
For Win32 the terminal window is not used when the input or output is
redirected, e.g. for:
:10,30w !wc
The reason is that it appears that Winpty doesn't do the redirection.
The whole of "</tmp/somefile" is seen as a file name. Does someone want
to look into making that work? You can force it to work by removing the
check for "options" in mch_call_shell():
/* TODO: make the terminal window work with input or output redirected. */
if (vim_strchr(p_go, GO_TERMINAL) != NULL
&& (options & (SHELL_FILTER|SHELL_DOOUT|SHELL_WRITE|SHELL_READ)) == 0)
Unfortunately, the colors, like with the color_ramp example, don't work
well in Win32. The console only supports 16 colors, but at least some
of them should show up.
Depending on how well it works I intend to add "!" to 'guioptions' by
default. As it is now, probably not for Win32. Even though it would be
most useful there.
