Use rpmspec LSP instead of maintaining own parser

Is your feature request related to a problem? Please describe.

I actually do not know what the difference it would bring, but I wanted to point out that there is a rpmspec Langugage Server Protocol project (rpm-spec-language-server)

Maybe this reference would help consider the transition:

• https://plugins.jetbrains.com/docs/intellij/language-server-protocol.html#basic-implementation

Describe the solution you'd like

Use the rpm-spec-language-server project.

Describe alternatives you've considered

Please also consider LSP4IJ https://github.com/redhat-developer/lsp4ij

You can test quickly your language server without developping an IJ plugin just with settings to declare your start server command and mappings files

Please read https://github.com/redhat-developer/lsp4ij/blob/main/docs/UserDefinedLanguageServer.md

If you can make a guide to integrate in a plugin that would be wonderful, i.e. how to make a plugin from scratch for language foo using your plugin as a dependency. There are non-LSP stuff that are worth keeping and developing in a project like this, e.g. creating a spec file from a template or name.

Please read doc at https://github.com/redhat-developer/lsp4ij/blob/main/docs%2FDeveloperGuide.md

But it will require IJ plugin dev skills. If you have no the skills, I suggest to write an lsp4ij lsp template where the idea is to declare start command, file mapping with json files.

First start with

https://github.com/redhat-developer/lsp4ij/blob/main/docs/UserDefinedLanguageServer.md and once it will work you can export that as lsp template and you could contribute to LSP4IJ, see
https://github.com/redhat-developer/lsp4ij/blob/main/docs/UserDefinedLanguageServerTemplate.md

By contributing with an lsp temolate, user will need just to install lsp4ij and will able to use your lsp template like https://github.com/redhat-developer/lsp4ij/blob/main/docs/user-defined-ls/astro-ls.md

If you need help please ask me.

If you need sample of plugin which uses lsp4ij, please see https://github.com/redhat-developer/lsp4ij?tab=readme-ov-file#who-is-using-lsp4ij
