How to configure the Formatter?

[JoaquimEsteves]

Hello,

I'm brand new to the D lang - first of all I'd like to extends my thanks for providing us with such lovely free software.

My question revolves around the formatter that comes packaged with this LSP.
I can't seem to edit my preferred settings (for example: curly braces style)

I'm using NeoVim and have just installed this LSP, with the following (default) setup:

require'lspconfig'.serve_d.setup{}

I also made sure to add both dcd-server and dcd-client to my path.

I saw that the dftm allows me to configure such things - but can't figure out the way to pass such information over through the LSP.

Is there some sort of config option I can set on dub.json?

Furthermore - is there I way I can set it up without having a dub.json? I'd like for my formatting options to be constant even when I'm just using writing to some one off file (for example rdmd my_cool_script.d)

this depends on your LSP client and how you can pass configuration to it. Basically serve-d takes the project configuration and in there there are options to configure with dfmt.

The available settings as D struct:

serve-d/source/served/types.d

Lines 119 to 135 in 1a26dcd

	struct DFmt
	{
	@serdeOptional:
	bool alignSwitchStatements = true;
	string braceStyle = "allman";
	bool outdentAttributes = true;
	bool spaceAfterCast = true;
	bool splitOperatorAtLineEnd = false;
	bool selectiveImportSpace = true;
	bool compactLabeledStatements = true;
	string templateConstraintStyle = "conditional_newline_indent";
	bool spaceBeforeFunctionParameters = false;
	bool singleTemplateConstraintIndent = false;
	bool spaceBeforeAAColon = false;
	bool keepLineBreaks = true;
	bool singleIndent = true;
	}

or as JSON schema: https://github.com/Pure-D/code-d/blob/b19258b82d40b72ac4e60497214de14a4248d4d8/package.json#L763

Line endings, indentation size and style (tabs/spaces) should be synced with your standard editor configuration. So if the editor inserts tabs/spaces, the auto-formatting should use the same. (otherwise it might be a NeoVim LSP bug)

You will have to consult the NeoVim LSP documentation to see how to set the configuration values. If you find a way, feel free to submit a PR to the editor-vim.md file in the repository

Ahhh! I see.

With your suggestions I was able to solve the braces issue like so:

lspconfig.serve_d.setup({
	on_attach = my_on_attach_func,
	settings = {
		dfmt = {
			braceStyle = "stroustrup", -- or your desired style 
		},
	},
})

I'd be glad to make a PR to the editor-vim.md; I just need a few pointers.

My nitpick is discoverability - if I type DFmt as the types file suggests then it doesn't work - it has to be written in the same style as the package.json

That's fair enough, but it feels weird to me to tell the reader "read the package.json of a separate git repo to see how you can tweak serve-d".

I see that that's how it's setup in the main README but I was wondering if there was a better way to point new users like myself to this information.

yeah could add the information here as well - it would need to be automatically generated though since it's a pain to maintain multiple versions of the same thing. Could maybe add it to the output of serve-d --help

[JoaquimEsteves]

That would be absolutely ideal. Thanks so much for your help.
