@Konfekt Can you open a pull request against devel branch?
from fzf.
This is the Git Bash terminal from Git for Windows. It is from scoop install git
.
from fzf.
from fzf.
I had MSYS=winsymlinks:nativestrict
in my .bashrc, which allowed fzf to work. MSYS=
causes fzf to hang, as expected.
(MSYS=winsymlinks:nativestrict
allows ln
to create symlinks in Windows.)

Which "Fzf plug-ins" do you mean?
I checked with https://github.com/chrisant996/clink-fzf and https://github.com/kelleyma49/PSFzf on cmd and powershell. It's working fine now. Good work!
from fzf.
This checks for the Win32 version of Vim, using Unix files (Cygwin), according to :help feature-list
, but Cygwin nowadays rather refers to MSYS2.
One striking difference is that it expects Unix paths.
As vim
in Git Bash is the default Vim, we looked no further.
By has('win32unix')
being true, we know not only that this is most likely Git Bash vim, but also that the Git Bash executable exists, used by line 714.
So yes, one could likely check for something like has('win32unix') || (has('win32') && &shell =~# '\v<(ba)?sh>')
instead of has('win32unix')
Likely only its original author @janlazo can tell us why $TERM !=# 'cygwin'
must be ensured.
from fzf.
Why does it need to be run as a cmd.exe process?
Removing this branch lets Git Bash's vim use the unix branches and most importantly does not cause a separate cmd.exe Window to appear.

Is it? What does branch refer to? If you mean spawning cmd.exe, that would be great.
Again, this code was added in #933 whose authors know better. The Wiki says
On Cygwin, install script will download the prebuilt fzf binary for Windows platform. It does not run on mintty, the default terminal emulator shipped with Cygwin, but it works fine on ConEmu or the default Command Prompt (cmd.exe).
The Vim plugin of fzf also works with the Windows binary. It will start an extra cmd.exe window on mintty to circumvent the aforementioned limitation.
but seems somewhat outdated, since now the dev branch already supports Fzf in Git Bash default Mintty term.
Mind that #3804 asks similarly if the spawning of cmd.exe could be removed.
Maybe with the latest changes this is indeed possible.
For starters, does
let command = 'start /WAIT sh -c '.shellscript
suffice?
from fzf.
If I understand correctly, in latest Git Bash simply
instead of the involved cmd.exe shell script execution suffices.
Did you check :FZF
to work as expected for all kind of paths, namely with spaces?
from fzf.
Yes, see the image below:
However, it executes it in full screen. Is this is normal behavior on a unix system or is this an artifact of some other has('win32unix') check?
from fzf.
For me :FZF $path
without the above shown if-branch worked out-of-the-box in Windows Terminal, but not in Git Bash's default Mintty terminal.
However, it did with the exe from the dev
branch using winpty.
Therefore I suspect that this if-branch was needed to make fzf
work in Git Bash without winpty (which maybe wasn't included in Git bash from the start?) and we can drop it together with the next release.
If you could confirm that all commands work as expected under the Git Bash Terminal as well?
from fzf.

Maybe that could be part of the next release since it yet improves again on the Git Bash experience
from fzf.
Since 573df52
(#3807) seems to call winpty directly, the check for win32unix could be replaced by executable('winpty')
.
This would also make it clearer, if guessed correctly, why all the convolution
Lines 711 to 716 in daa6024
from fzf.
Interestingly, I can use fzf in Git Bash without winpty. I don't know why that is.
0.52.1 (6432f00)
fzf also works for me with no ~/.bashrc
.
from fzf.
Phew, to confirm: that might be because this terminal is from MSYS2 itself, not the somewhat more restricted Git Bash MSYS2? For most users, Vim in MSYS2 will be Vim in Git Bash, so that's a case to be accounted for.
from fzf.
I can confirm that fzf.exe 0.52.1 works in Git Bash Mintty under Windows 11; it does not under Window 10.
from fzf.
Maybe it's solved in Windows 11, and winpty only needs to be used after a check for Windows 10 in fzf.exe, such as
var osvi OSVERSIONINFOEXW
osvi.dwOSVersionInfoSize = uint32(unsafe.Sizeof(osvi))
mod := syscall.NewLazyDLL("kernel32.dll")
proc := mod.NewProc("GetVersionExW")
ret, _, _ := proc.Call(uintptr(unsafe.Pointer(&osvi)))
if ret != 0 {
if osvi.dwMajorVersion == 10 {
...
from fzf.
No, this was not about the OS versions. It was rather about the difference between git 2.42.0 and 2.45.1.
@junegunn Fzf in latest Git Bash Mintty no longer seems to need the winpty workaround.
Here's where were at: #3809 (comment)
from fzf.
@ykhan21 You may check with an older Git Bash, confirming #3809 (comment)
from fzf.
I am not sure what might have changed regarding winpty in Git Bash, from crawling their repo there's nothing striking and the release notes https://github.com/git-for-windows/build-extra/blob/main/ReleaseNotes.md#known-issues still state that winpty is often needed. A comment two month ago by its maintainer reinstating it
from fzf.
Here we go, this might have tickled down from mintty to Git Bash: https://github.com/mintty/mintty/wiki/Tips#inputoutput-interaction-with-alien-programs
When interacting with programs that use a native Windows API for command-line user interaction (“console mode”), a number of undesirable effects used to be observed; this is the pty incompatibility problem and the character encoding incompatibility problem. This would basically affect all programs not compiled in a cygwin or msys environment (and note that MinGW is not msys in this context), and would occur in all pty-based terminals (like xterm, rxvt etc).
Cygwin 3.1.0 compensates for this issue via the ConPTY API of Windows 10. On MSYS2, its usage can be enabled by setting the environment variable MSYS=enable_pcon (or selecting this setting when installing an older version). You can also later set MSYS=enable_pcon in file /etc/git-bash.config. MSYS2 releases since 2022-10-28 enable ConPTY by default. You can also set mintty option ConPTY=true to override the MSYS2 setting.
As a workaround on older versions of Cygwin or Windows, you can use winpty as a wrapper to invoke the Windows program.
Indeed MSYS=enable_pcon makes fzf work even on older Git Bash terms
from fzf.
So Fzf could suggest
-
either installing a recent mintty (> 2022-11 which supposedly is https://github.com/mintty/mintty/releases/tag/3.6.2 but mintty 3.6.4 in Git Bash 2.42.1 does not enable it by default; likely 3.7.0 does) which is included also in most recent Git Bash >= 2.43 according to https://github.com/git-for-windows/build-extra/blob/34a82b52c89920c425b691e8ae61a8eed47152dd/versions/package-versions-2.43.0.txt,
-
if that's not an option, setting
MSYS=enable_pcon
in~/.bash_profile
or/etc/git-bash.config
for mintty including mintty/mintty@6999ae7 from 2021-02, that is https://github.com/mintty/mintty/releases/tag/3.4.5 which statesNew settings -P/--pcon/ConPTY to enable/disable ConPTY support (mintty/wsltty#271).
This is included in Git Bash >= 2.31.0 according to https://github.com/git-for-windows/build-extra/blob/34a82b52c89920c425b691e8ae61a8eed47152dd/versions/package-versions-2.31.0.txt
-
for mintty < 3.4.5, that is Git Bash < 2.31.0 (2021-02) the winpty workaround is still needed
-
if there's no winpty, then in Vim this still can be worked around by spawning
cmd.exe
as has been fzf's default approach till today
Once settled how fzf handles this, the Wiki entry https://github.com/junegunn/fzf/wiki/Cygwin can be updated
from fzf.
Good thing: Mintty provides the environment variable $TERM_PROGRAM_VERSION
to check for these.
So how about something similar to
func main() {
termProgramVersion := os.Getenv("TERM_PROGRAM_VERSION")
if compareVersions(termProgramVersion, "3.7.0") >= 0 {
return
} else if compareVersions(termProgramVersion, "3.4.5") >= 0 {
originalMSYS := os.Getenv("MSYS")
os.Setenv("MSYS", "enable_pcon")
defer os.Setenv("MSYS", originalMSYS)
} else {
if isWinptyAvailable() {
// Use fzf-0.52.1-dev code ...
} else {
// Use fzf-0.52.1 code ...
}
}
}
func compareVersions(v1, v2 string) int {
parts1 := strings.Split(v1, ".")
parts2 := strings.Split(v2, ".")
for i := 0; i < len(parts1) && i < len(parts2); i++ {
if parts1[i] > parts2[i] {
return 1
} else if parts1[i] < parts2[i] {
return -1
}
}
return 0
}
func isWinptyAvailable() bool {
_, err := exec.LookPath("winpty")
return err == nil
}
from fzf.
@Konfekt Thanks, but my Git bash reports 3.7.1
but fzf doesn't run without winpty
.

MSYS=enable_pcon ./fzf --no-winpty
works great, and it gives accurate colors and border.
from fzf.
However, even with MSYS=enable_pcon
, --height
doesn't work.
from fzf.
my Git bash reports 3.7.1 but fzf doesn't run without winpty.
Hm... 3.7.0 was a guess; supposedly 3.6.4 should have worked, but neither did for me.
3.7.1. is used in latest https://github.com/git-for-windows/build-extra/blob/34a82b52c89920c425b691e8ae61a8eed47152dd/versions/package-versions-2.45.1.txt and it worked for me in Scoop;
according to their (install script](https://github.com/ScoopInstaller/Main/blob/master/bucket/git.json) they don't seem to make many adaptions.
even with MSYS=enable_pcon, --height doesn't work.
Was this ever addressed? In 573df52
(#3807) it seemed like rather not
from fzf.
For what it's worth, I also content myself with
func main() {
termProgramVersion := os.Getenv("TERM_PROGRAM_VERSION")
if compareVersions(termProgramVersion, "3.4.5") >= 0 {
originalMSYS := os.Getenv("MSYS")
os.Setenv("MSYS", "enable_pcon")
defer os.Setenv("MSYS", originalMSYS)
} else {
if isWinptyAvailable() {
// Use fzf-0.52.1-dev code ...
} else {
// Use fzf-0.52.1 code ...
}
}
}

@Konfekt Please review and test d4216b0

Would you mind attaching the exe? I did not find a devel mingw compile action https://github.com/junegunn/fzf/actions
from fzf.
from fzf.
It works fine in Git Bash 2.42.0.
Mintty < 3.4.5 is three years old, so maybe it's not worth to rack one's brain too much about it,
even less so for Mintty < 3.4.5 without winpty.
For the Vim plugin, the condition has become
elseif has('win32unix') && $TERM_PROGRAM ==# 'mintty' && $TERM_PROGRAM_VERSION =~# '\v^[0-2]\.|3\.[0-3]|3\.4\.[0-4]' && !executable('winpty')
from fzf.
Nice, a moment's thought would have suggested to me that there's already a s:compare_versions
for such a long-lived versatile program.
from fzf.
Maybe time has come to update the wiki
from fzf.
Has anyone tested with Windows Terminal(different from the builtin cmd console) as an alternative terminal to mintty?
And there might be other terminals on windows that load git-bash... (how about the builtin terminal of VSCode ?)
from fzf.
Windows Terminal was never a trouble-maker to begin with, fzf
worked fine in it and then also :FZF
in vim in it. Has it become one now?
from fzf.
There is this old issue with fzf+Git Bash. I wonder if the new changes fixes it.
#3346
from fzf.
I had MSYS=winsymlinks:nativestrict in my .bashrc, which allowed fzf to work. MSYS= causes fzf to hang, as expected.
Thanks for pointing that out, so it's indeed a list of options. There are some doubts on their separators, though.
I found MSYS
on Git Bash 2.42. to default to MSYS=disable_pcon
.
@junegunn : That should explain why fzf kept not working on mintty 3.6.4 since Git Bash explicitly sets MSYS=disable_pcon
, so the new default of mintty never came into play. (You need to check the "enable experimental support for pseudo consoles" checkbox when installing Git Bash.)
To complicate Portable Git now enables pcon, whereas the classic install not.
from fzf.
Somehow I'd trouble with Ctrl-T
in the Fzf plug-ins for cmd and powershell with this version; just a reminder to check that the fixes on the Git Bash end do not cause regressions on the former two ends.

Which "Fzf plug-ins" do you mean? Are you referring to the shell integration scripts in this repo? I don't think they're supposed to work on cmd or powershell.
from fzf.
Hmm, --height
seems to be broken, let me look into it.
from fzf.
With a series of fixes, now everything seems to work nicely.
--height
options works on Git bash, cmd, and powershell- Shell integration works on Git bash (
eval "$(fzf --bash)"
)

You can test this binary:

from fzf.
Thanks for the fix.
@Konfekt, a minor thing on mintty: with export MSYS=disable_pcon
, the selection of ls | fzf
(the output) gets cleared. cd "$(ls | fzf)"
works, however.
