Error when using with Cygwin

[RT-Tap]

Hey, first off I want to thank all contributors for this really cool project! Also I know Cygwin isn't officially supported however it seems to work or at least the base functionality does.

So I successfully got oh-my-posh working without much effort or changing anything just used the linux version of oh-my-posh on Cygwin. However I keep getting an error and the path portion of a theme says INVALID CONFIG PATH. The Error is as follows:

Oh My Posh Error:
 CreateFile /cygdrive/c/Users/me/iterm2.omp.json: The system cannot find the path specified.

I believe this is because Cygwin prefaces normal system directories with /cygwin/ so for example C:/Users/Me/Documents/ would be /cygwin/c/Users/Me/Documents/ and directories in cygwin's directory aren't changed at all, or rather the change is it treats it's root directory as the root directory and anything outside is prefaced with /cygwin/. However I get this error even when in Cygwin's home directory where using the command pwd would result in a path like /home/me.

Any Idea how i could fix this? Would I need to compile from scratch and change some file location configs or something along those lines?

Maybe I can do some enviroment variable changes? However I don't want to break literally everything else so doubt this is a good idea.

Also to save HD space (minimal I know but efficiency) I simply symlinked .poshthemes in my cygwin directory to the themes folder in my Windows instance but I don't think this is part of the issue or at least doesnt seem to be.

What's your bash config like?

[RT-Tap]

Sorry if I misinterpreted you question or just ignorant to a different config but in .bashrc I only have the following:

[[ "$-" != *i* ]] && return
eval "$(oh-my-posh --init --shell bash --config ~/iterm2.omp.json)"

EDIT: in /cygwin/etc/bash.bashrc I have

# Check that we haven't already been sourced.
[[ -z ${CYG_SYS_BASHRC} ]] && CYG_SYS_BASHRC="1" || return

# If not running interactively, don't do anything
[[ "$-" != *i* ]] && return

# Exclude *dlls from TAB expansion
export EXECIGNORE="*.dll"

# Set a default prompt of: user@host and current_directory
PS1='\[\e]0;\w\a\]\n\[\e[32m\]\u@\h \[\e[33m\]\w\[\e[0m\]\n\$ '

In /cygwin/etc/profile i have:

So actually I just notice that in PowerShell I get a NO CONFIG message in that field, without the error message above the prompt (so just the theme seems to be broken without an error message above the prompt like in Cygwin bash). But only for this theme (maybe others as well?). Not sure what that field is/displays exactly because it isn't included in other themes but there is obviously some issue system wide.

Anyway this is what is in C:\Users\ME\Documents\WindowsPowerShell\profile.ps1:

# !! Contents within this block are managed by 'conda init' !!
(& "C:\Users\Artyt\anaconda3\Scripts\conda.exe" "shell.powershell" "hook") | Out-String | Invoke-Expression
oh-my-posh --init --shell pwsh --config ~/blue-owl.omp.json | Invoke-Expression

[JanDeDobbeleer]

Are you sure you have those files in your $HOME directory? As I have a working git bash shell on my machine with the following line in my .bashrc: eval "$(oh-my-posh --init --shell bash --config ~/.jandedobbeleer.omp.json)"

[RT-Tap]

Yea. I'm pretty sure.
So powershell doesn't have this issue, not sure wtf I did or what happened but the issue is gone.
Now for Cygwin (using bash), I did echo $HOME it printed /home/Artyt and that's where my .bashrc file is with the eval "$(oh-my-posh --init --shell bash --config ~/.theme.omp.json)" line in it. Also in that folder I have a symlink named .poshthemes that links to the folder where the themes for my Windows install are.

If I start bash from /bin/bash the eval line get's evaluated because oh-my-posh starts, however with the error : Oh My Posh Error: CreateFile /home/Artyt/iterm2.omp.json: The system cannot find the path specified. and the INVALID COFIG PATH in the actual prompt. I tried replacing the theme name and running . ~/.bashrc but nothing happens I just get the same Error message.
This leads me to ask two questions:
Why is oh-my-posh trying to create the file ~/theme.omp.json? Should it not be ~/.poshthemes/theme.omp.json?
What type of config file are they talking about here? A config file for oh-my-posh or a bash/shell profile?

Also, I also use Eugeney/Tabby (used to be named Terminus - If your unfamiliar it's like fluent terminal or just one of those terminal emulators where you can run multiple shells and/or SSH connections in a tabbed window) and I could have sworn that when I first installed oh-my-posh it worked/showed up correctly in Tabby (for Cygwin that is, no problems with powershell), but now it's just the standard prompt. It shouldn't be though because if i run /bin/bash it has the oh-my-posh prompt albeit one with an error. But maybe there is something that can be said about the discrepancy.

[JanDeDobbeleer]

Did you symlink the .poshthemes folder or each theme individually? Otherwise you need to also include the folder in the path OR symlinks simply don't work for this use-case.

[mreduar]

Hi, I am also having the same problem with Cygwin.
Is there any solution for this?

I also try with eval "$(oh-my-posh --init --shell bash --config ~/craver.omp.json)" and it is the same

I use Git Bash and everything works perfect there, but I would like to move to Cygwin, however I get this error.

[JanDeDobbeleer]

You should use Windows paths as you're still on Windows and golang needs to use the Windows API's. ~ won't work as it resolves to the same path. Find the actual location and use that.

[mreduar]

Thanks
eval "$(oh-my-posh --init --shell bash --config C:/Users/<username>/cygwin64/home/<username>/<config.json>)" works

[rohit-kumar-j]

Thanks @mreduar , I did a similar thing, but cloned the git repo with all the themes in my .config folder and ran it like this...

eval "$(oh-my-posh --init --shell bash --config C:/cygwin64/home/jsk71/.config/oh-my-posh/themes/jandedobbeleer.omp.json)"

it worked!

[GameLord2011]

This is probably a very dumb question, but how does one install it in the first place, can I just insert the path to the Windows executable, as cygwin is just a POSIX compatibility layer for Windows?

[JanDeDobbeleer]

Not really as the Windows path doesn't exist. All it needs is to have the executable in your PATH which will simply make it available.

[GameLord2011]

It seems to use the Windows PATH,

(I replaced my hostname w/ the *'s)

[JanDeDobbeleer]

If you want to use oh-my-posh and not the full path (which would need to be cygwin and not Windows path, you need to make sure the oh-my-posh.exe file is available in one of those folders. Now, the installer will do that for you (restart the terminal after install to reload the PATH).
