Add code action to generate doc comments

[minhduc0711]

Hi, is it possible to add a code action for generating Java doc comments like this?

[mfussenegger]

See #76 - it is possible via snippet. There is no dedicated code action for it as far as I'm aware.

[minhduc0711]

Ah sorry for not catching that issue. The auto-indent does not work for me for some reason though...

[mfussenegger]

Could be that the indentation settings of the editor weren't picked up because of a missing didChangeConfiguration.

Could you try again with #92 being merged?

[minhduc0711]

Hmm #92 does not seem to fix it.

Which eclipse.jdt.ls version are you using? eclipse-jdtls/eclipse.jdt.ls#1657 is required for it to pick up indentation/tab settings.

[minhduc0711]

I'm using jdtls-1.1.2-1, the latest one I think.

You could try setting the format options explicitly in your config:

local config = {
  settings = {
    java = {
      format = {
        insertSpaces = vim.api.nvim_buf_get_option(bufnr, 'expandtab'),
        tabSize = vim.lsp.util.get_effective_tabstop(bufnr)
      }
    }
  }
}

These options are automatically added by nvim-jdtls if they are absent. Not sure why it isn't working for you.

Maybe your neovim expandtab/tabstop settings don't match the indentation style of your java file?

[minhduc0711]

When I hit TAB, indentation is correct so I guess the neovim settings are fine.

The explicit config does not fix it still. Am I doing this correctly?

local config = {
  cmd = {'java-lsp', workspace_folder},
  settings = {
    java = {
      format = {
        insertSpaces = vim.api.nvim_buf_get_option(bufnr, 'expandtab'),
        tabSize = vim.lsp.util.get_effective_tabstop(bufnr)
      }
    }
  }
}
require('jdtls').start_or_attach(config)

Try setting the snippetSupport option after settings in your config:

local config = {
  settings = {
    java = {...}
  },
  capabilities = {
    textDocument = {
      completion = {
        completionItem = {
          snippetSupport = true
        }
      },
    },
