Version Information

Cmder 1.3.19.1181 Clink provide with Cmder 1.2.46 Clink latest 1.3.42.ef446e Windows Terminal 1.15.2524.0 (but problem also appears in conemu) Windows 10 Version 21H1 (Build 19043.2006)

Description of the issue

I'm trying to get oh-my-posh running but with the embedded Clink the input is horrible slow: yes, this is real time copy-past ;-)

with the latest clink version it is a little bit better:

[chrisant996]

This looks like an oh-my-posh issue (not a Clink issue, and not a Cmder issue). There is a pause every time you press Space.

Oh-my-posh binds a custom command to the Space key. The custom command invokes the oh-my-posh.exe program every time you press Space. The reason it binds a custom command to the Space key is so that it can change the right-side prompt depending on what command word has been typed.

@JanDeDobbeleer The custom command needs to be more efficient. One cheap option could be to only invoke oh-my-posh when the command word changes; then there would usually only be a delay the first time Space is pressed. Another more sophisticated option could be to update the oh-my-posh Lua script to use Asynchronous Prompt Filtering. We can chat here, or you can send me an email to the address in my github profile and we can chat offline and post an update here later.

[JanDeDobbeleer]

@chrisant996 we already make use of async prompt filtering so that should be good. I also just created a change that will only enable this functionality when you've set custom tooltips (it was enabled all the time). Can you point me to the docs on command word changes?

But still, the issue stands. The version needs to be updated :-)

[chrisant996]

@andi-blafasl With recent versions of OMP, I do not see the reported behavior. There is a delay, but only when initially showing the prompt, and when Space is pressed the first time.

• What version of Oh-My-Posh are you using?
• Which OMP theme are you using? (And what version of the theme?)
• Are you using the one-line oh-my-posh.lua script from the docs? If not, then try using the one-line script so that it can stay current with OMP updates.

@JanDeDobbeleer I looked at OMP v10.0.1 and it uses a coroutine for the right side prompt, but it doesn't use Clink's Asynchronous Prompt Filtering support.

On my fast gaming laptop, OMP uses ~260 ms in a non-git directory, and ~340 ms in a relatively small git repo with no modified files. OMP can achieve 0-2 ms if it uses Clink's Async Prompt Filtering support.

Some observations for the OMP init script:

• The ohmyposh_space is already only refiltering when the command word changes. That looks good in v10.0.1; it will be informative to find out what version of OMP the OP is using.
• In ohmyposh_space, ideally the rl_buffer:insert(" ") should happen first, so that it gets the correct first word even when for example Space splits gitcommit into git commit.
• OMP is not using Clink's Async Prompt Filtering. There is no call to clink.promptcoroutine(), which is the key to asynchronous prompt filtering. It's possible for a script to try to do all the work itself, but it's pretty difficult for a script to prevent redundant/unnecessary concurrent prompt filter calls on its own. When a script uses clink.promptcoroutine(), Clink does a bunch of work to make sure only one instance of the prompt coroutine runs at a time, it queues additional coroutine requests, and it intelligently discards obsolete queued prompt coroutine calls. Clink goes to some trouble to avoid spawning lots of concurrent processes, and it automatically handles all the caching magic.
• The left side prompt never uses a coroutine (always has a delay).
• The right side prompt normally does not use a coroutine (normally has a delay).
• The tooltip functionality (pressing Space) triggers re-filtering the prompt:
  • The left side prompt tries to reuse what it already has (i.e. tries to not run OMP); if it doesn't have anything, then it runs OMP (has a delay).
  • The right side prompt creates a coroutine that runs a new OMP in the background to produce a right side tooltip prompt (async, but doesn't allow Clink to optimize it).

For OMP to fully utilize Clink's async prompt filtering and be the most responsive, OMP would need to communicate with itself about the previous values it used for "expensive" operations, and then reuse those values for the initial synchronous spawn of OMP, and trigger an async spawn of OMP to recalculate updated values for the "expensive" operations.

For Clink v1.3.43, I've added diagnostic output in Clink to report costs for prompt filters (Alt-1,Ctrl-X,Ctrl-Z).

Here is OMP in a plain non-git directory with the jandedobbeleer.omp.json theme. I included flexprompt costs, pasted in from a separate run, for convenience.

@chrisant996 thanks. Seems like I have some studying to do. But this part is a no go architecturally:

OMP would need to communicate with itself about the previous values it used for "expensive" operations

These are only expensive on Windows btw, not kidding either. Git is significantly slower on Windows (also for the oh-my-posh repo).

[chrisant996]

@chrisant996 thanks. Seems like I have some studying to do. But this part is a no go architecturally:

OMP would need to communicate with itself about the previous values it used for "expensive" operations

@JanDeDobbeleer In that case, there are three basic categories of options:

1. No change; use what OMP is currently doing, which has a delay when showing the prompt, but should be responsive when typing Space (but it's unclear why the OP is experiencing lag, unless an older version of OMP is being used).
2. Adjust what OMP is currently doing, so that it uses clink.promptcoroutine() instead of coroutine.create() (and remove the logic that tries to avoid creating more than one coroutine at a time -- clink.promptcoroutine() handles that and several other things automatically). It's not a straight "rename the function call", though -- they work differently, so additional adjustments will be needed. Let me know if you'd like me to take a stab at it.
3. Use async prompt filtering for all 4 filter functions, and let the previous prompt show until OMP finishes, at which point the prompt will refresh with the latest result. This would involve making the normal :filter() function (and normal :transientfilter() function) asynchronously run OMP for both the left and right prompts, and cache the right prompt result, and then in the :rightfilter() function use the cached result. Because you get only one clink.promptcoroutine() per prompt filter, which is what enables the caching to work and achieve the high responsiveness. I might have designed it a little differently if right-filter support had come first, but it is what it is.

My recommendation would be option 3 if responsiveness is considered more important than initial accuracy after e.g. changing the current working directory.

OMP is mostly already avoiding concurrent instances, so the benefit of option 2 seems relatively low by itself, unless/until reports come in about extra OMP instances running concurrently (there are edge cases that can happen, e.g. when pressing Enter and clink.promptcoroutine() would prevent them, but again it's probably not worth doing option 2 by itself).

[JanDeDobbeleer]

@chrisant996 I'll first need to get clink to work on my ARM VM. For some reason it simply refuses to load. Probably pebcak...

[chrisant996]

There's no ARM version of Clink. You'll have to start the x64 or x86 cmd.exe in order to be able to inject Clink.

[chrisant996]

P.S. @JanDeDobbeleer let me know if you want me to take a stab at option 3.

[JanDeDobbeleer]

There's no ARM version of Clink. You'll have to start the x64 or x86 cmd.exe in order to be able to inject Clink.

Tried that, must've done something wrong.

@chrisant996 yes, if you want to you can give it a go.

@andi-blafasl With recent versions of OMP, I do not see the reported behavior. There is a delay, but only when initially showing the prompt, and when Space is pressed the first time.

• What version of Oh-My-Posh are you using?
• Which OMP theme are you using? (And what version of the theme?)
• Are you using the one-line oh-my-posh.lua script from the docs? If not, then try using the one-line script so that it can stay current with OMP updates.

@chrisant996 I updated OMP to the latest 10.0.1 Version last friday. Today I tested it and there is no delay after pressing space any more. Not sure if it makes a difference, but I'm outside the Office-LAN at Home today. The Theme is a trimmed down Version of Atomic. I included it in the Issue OMP 2815 That's the way I use to integrate OMP with cmder

cat oh-my-posh.lua
load(io.popen('oh-my-posh init cmd --config %USERPROFILE%/.mytheme.omp.json'):read("*a"))()

Just saw there is Version 10.2.0 available with winget. Here is an updated debug output:

BTW: A college at my company is also experiencing the slow startup and the long waiting time between two prompts (by just hitting enter). We both installed OMP on our private Systems at Home and there is nearly no delay between two prompts and the runtime in the debug is also very small. Don't have the exact numbers right now, sorry Any Ideas how to debug this problem on our business machines?

[daxgames]

I know from experience here with Cmder that business machines can be an issue that is hard to crack. That could be a tough one.

[chrisant996]

If the business machines let you add exceptions to the antivirus/anti-malware suite, try adding exceptions for oh-my-posh and git (use task manager or etc to figure out which executables are taking a long time to run, and add exceptions for them).

If not ... then you're probably stuck with the delays.

[andi-blafasl]

@chrisant996 I already made an exception for the oh-my-posh executable. The delay was reduced, the exception works. But now even if I disable the Antivirus on my machine completely, there is no difference in timing. ¯\_(ツ)_/¯

[chrisant996]

@andi-blafasl which timing, where, for how long?

Try to use task manager or etc to figure out which executables are taking a long time to run, and add exceptions for them.

oh-my-posh.exe is only one of multiple executables that may be running.

You'll have to dig into this a bit and examine what's happening on the machine.

[chrisant996]

There's no ARM version of Clink. You'll have to start the x64 or x86 cmd.exe in order to be able to inject Clink.

Tried that, must've done something wrong.

@chrisant996 yes, if you want to you can give it a go.

@JanDeDobbeleer I have some proposed changes, and maybe some bug fixes. I'll put together a PR sometime this coming week.

Short version -- omp is now highly responsive except in two cases:

1. Right after changing the current working directory, initially the new prompt must be generated immediately, instead of being async.
2. The transient prompt has a noticeable delay. It could be optimized if omp can detect when the transient prompt is a fixed string, and make the Lua script natively return the fixed string without invoking the omp exe (since omp already generates the script with some internal configurations based on the special theme that's been specified).

[chrisant996]

PR is available at https://github.com/JanDeDobbeleer/oh-my-posh/pull/2951.

Sorry for the delay ... I plain forgot about it. 🙃

[JanDeDobbeleer]

@chrisant996 we're only human. And busy enough already 😅

[daxgames]

This may be a dumb question but what does Clink have to do with OMP since Clink is a shell enhancement for Cmd and not Powershell? I think I am missing something. Thanks in advance.

[JanDeDobbeleer]

@daxgames oh-my-posh can run in any shell as of the last 2 years. I guess that's the context you're missing.

[chrisant996]

OMP supports Clink now, and for each shell OMP has a different built-in custom script for integrating with the shell. We've been working on optimizing OMP in Clink so that it doesn't cause lags/pauses.

This issue (2751) is at its root about OMP, moreso than either Cmder or Clink. But the OP observed that a newer Clink made the delays a little shorter, so the OP requested Cmder to update to a newer Clink. However, the main issue was that a newer version of OMP needed to be used. Along the way Jan and I found some additional ways to improve OMP.
