Simplify PSES CLI so startup with non-Code editors is easier

[andyleejordan]

It takes way too many arguments to launch PSES correctly, which is blocking #1829. Once we simplify this, we could conceivably add a -lsp flag to PowerShell itself that would simplify it even further.

How definitive is this? Do you intend to completely rewrite the CLI/introduce "breaking changes" with this? I imagine that any changes you would make would have to be backwards compatible.

But I have to ask, since my PSES manual controller is dependent on how your CLI works.

[andyleejordan]

I don't intend to make breaking changes. The best coverage I have for that is

PowerShellEditorServices/test/emacs-test.el

Lines 48 to 54 in 9416a8a

	`(powershell-mode
	. ("pwsh" "-NoLogo" "-NoProfile" "-Command" ,start-script
	"-HostName" "Emacs" "-HostProfileId" "Emacs" "-HostVersion" "1.0.0"
	"-BundledModulesPath" ,module-path
	"-LogPath" ,log-path "-LogLevel" "Diagnostic"
	"-SessionDetailsPath" ,session-path
	"-Stdio")))

and

PowerShellEditorServices/test/vim-test.vim

Lines 6 to 13 in 9416a8a

	let g:LanguageClient_serverCommands = {
	\ 'ps1': ['pwsh', '-NoLogo', '-NoProfile', '-Command',
	\ l:pses_path . '/PowerShellEditorServices/Start-EditorServices.ps1',
	\ '-HostName', 'vim', '-HostProfileId', 'vim', '-HostVersion', '1.0.0',
	\ '-BundledModulesPath', l:pses_path, '-Stdio',
	\ '-LogPath', g:repo_root . '/pses.log', '-LogLevel', 'Diagnostic',
	\ '-SessionDetailsPath', g:repo_root . '/pses_session.json' ]
	\ }
