No

Describe the solution you'd like

In mason-lspconfig we have the option to pass ensure_installed, a list of packages that mason will install automatically when the config is executed. I'd like to have the same feature for Mason to ensure non-lsp dependencies are installed.

Describe potential alternatives you've considered

I've seen people use null-ls to get this functionality from mason-lspconfig but it seems like a workaround and not a solution.

probably should be closed as duplicate of #103 #130 or #226 although I'd welcome this feature as well.

Closing as duplicate. I'll also add that this feature would be trivial to add, but I'm trying to ensure it fits well with future roadmap and that it won't suffer the penalties that'd be involved due to having to load significantly more code during setup. This can easily be added to your own config, for example:

• Add ensure_installed option #130 (comment)
• Provide an option to toggle the notification of installation status of mason-installed tools (LSPs, linters, formatters, debuggers etc) #1309 (comment)
