I have created a proof-of-concept plugin that hide the console window using
api hooking.

Re: [vim/vim] Is it very difficult to hide cmd window when calling 'system()' on windows ? (#922)

[Charles]

An alternative way without the need to modify vim is to create an
application that hook the CreateProcess function and modify the window
flags. It can be written e.g. in Python using the deviare library.

Yes, ctrl_break is not important, we can stop process by `kill` or `task 
manager`.

I like the modem noise in the old days too, but these feedbacks are sound 
feedback, not graphics feedbacks. 

We can see windows users asking for help to hide the cmd window, they need to 
focus on editing, and solutions are everywhere including patch of os_win32.c, 
python/perl script to emulate unix `system()` experience for vim. But none of 
these are perfect (depend on python or need modify official source code).

Can we get the ability to choose what ever we like ?
Could windows gvim users have an option to enable SW_HIDE in `system()` ?

I'm not sure if that can be made to work.  CTRL-Break sometimes behaves
strange.

On Unix you would use "kill" to stop the process.  On MS-Windows you can
use the task manager for this, right?

In general I don't mind the flickering, it's feedback that something is
happening.  (I liked to hear my harddisk rattling, to know how busy it
is, SSDs broke that.  I liked to hear my modem produce noise, so that I
knew what was going over the line. Now I have fiber...).

So, how can you stop these __very__ long time tasks from non-windows platform, 
which won't pop up a cmd window ?

__very__ long time tasks are supposed to be launched via async jobs in the 
latest vim version.

Could windows gvim stop the child processes by a Ctrl_C/Ctril_Break ?

There is an internal win32 message loop at line 4159 of os_win32.c:

https://github.com/vim/vim/blob/master/src/os_win32.c#L4159

which is used to update gui while waiting for child process finished.

Can we add a Ctrl_C/Ctrl_Break detection there to allow user stop a long time 
running process ? 

(I haven't read the whole part of os_win32.c, just do some search and find this
routine.)

If the child processes of 'system()' could be stop by ctrl_break/ctrl_c, could 
we make `system()` act the same way to the other vim versions ?

I am on the fence on this one.
If Vim shells out to run something and that something is taking a _very_
long time, your Vim is essentially hung.
This happens to me frequently.
At least with the Window there, I can close it, which returns an error to
Vim (via the system() call) and I get my Vim back.
Without that I have to terminate Vim, and that is a real pain.

It's quite effortless if you use the hg mirror and maintain the patches
with mq. Then to update to new version just run

hg qpop -a
hg update
hg qpush -a

If you compile vim yourself, you can simply change SW_SHOWMINNOACTIVE to
SW_HIDE in https://github.com/vim/vim/blob/master/src/os_win32.c#L4131.

I have used this patch for years (unfortunately I forget the source of the
patch) then just add let $VIM_SYSTEM_HIDECONSOLE=1 to vimrc or toggle the
value when necessary.
