RE: Tramp and conversion of \r\n into \n

Hi Michael,

I created a small test setup as follows:
- A mini C++ project
- An Emacs Lisp file with initializations for LSP mode
- A build script to create clangd
- A wrapper script for clangd, so you can see the output of clangd

Steps to do:
1. Setup clangd: The clangd version you mentioned is rather old, but you can try, if lsp mode works with that version. Otherwise I have added a small build script, which will generate clangd from its sources. It should install clangd somewhere into your path. This needs to be done on the 'remote' machine.
2. Put the wrapper-script somewhere into your path on the 'remote' machine. This simply redirects stdout and stderr of clangd, when it is invoked. This is referenced by the Emacs configuration.
3. Unpack the small example project and run the init.sh script in the project directory on the 'remote' machine. It will run cmake with the necessary options to generate a compile_commands.json file, which is needed by clangd.
4. Install lsp-mode with all its dependencies on the 'local' machine.
5. Make sure the initializations from the .el file are executed.
6. Now try to open the main.cpp file on the remote machine in Emacs on the local machine. This should trigger the start of clangd via lsp-mode. If the error occurs, the modeline shows 'clangd starting' forever.

Hope this helps,

Martin

Yes, pls send. There's also <https://snapcraft.io/install/clangd/fedora>,
would this be sufficient?

I don't lack other machines, running Tramp tests permanently :-)
