Config File Location After emacs Install?

[fahall]

Where is the omnisharp configuration file located after running omnisharp-install-server from within emacs? I looked in ~/.emacs.d/.cache/omnisharp/server, but did not see anything resembling a configuration json.

edit: there may not be an omnisharp configuration json file. I mistook an omnisharp-vscode issue for an omnisharp one.

What I'd like to do:

When running omnisharp-code-format-entire-file, I'd like open braces to NOT get their own lines:

void MyFunction (){

}

@fahall is there any particular setting that you would like to set?

Actually I didn't know that omnisharp server has any option to specify configuration file. Is this a new feature?

I tried to check for any options for the server but it seems there is none to specify confugration file:

user@pc v1.31.1 (develop)$ pwd
/Users/user/.emacs.d/.cache/omnisharp/server/v1.31.1
user@pc v1.31.1 (develop)$ ./run  --help


Usage:  [options]

Options:
  -? | -h | --help           Show help information
  -s | --source              Solution or directory for OmniSharp to point at (defaults to current directory).
  -l | --loglevel            Level of logging (defaults to 'Information').
  -v | --verbose             Explicitly set 'Debug' log level.
  -hpid | --hostPID          Host process ID.

@razzmatazz I am trying to set up the omnisharp-code-format-entire-file to use Stroustrup style braces (i.e. opening brace does NOT get newline). I can set this be the default as I type, but then if I run omnisharp-format-entire-file before saving, it puts the braces on their own line again. I had found this discussion on braces and newlines and thought there was an omnisharp settings file. Upon review, I was reading an issue for omnisharp-vscode and not just omnisharp.

With omnisharp-emacs, code style and syntax highlighting and parsing is done by the https://github.com/josteink/csharp-mode package (which can actually be used separately w/o omnisharp-emacs). Then, omnisharp-emacs provides language server integration with completion, xref and other functionality on top of csharp-mode.

csharp-mode uses cc-mode internally which exposes settings for code formatting. I.e. in my init.el I have:

  (defun sm-csharp-mode-setup ()
    (setq indent-tabs-mode nil)
    (setq c-syntactic-indentation t)
    (c-set-style "ellemtel")
    (setq c-basic-offset 4)
    (setq truncate-lines t)
    (setq tab-width 4)
    (local-set-key (kbd "C-c C-c") 'recompile))

  (add-hook 'csharp-mode-hook 'sm-csharp-mode-setup t)

Basically, I think c-set-style is what you are looking for and the options are listed here:
