JavaScript: Configures prettier to use single quotes

[aaronmcadam]

I've had to change the formatter for prettier directly to achieve this. There doesn't seem to be a configuration file for prettier, or a way to globally configure it.

I think a better idea would be to set a variable like let g:neoformat_javascript_args in my neovim configuration, but I'm not sure how to do that.

FYI, you can do this without forking https://github.com/fortes/dotfiles/blob/master/symlinks/config/nvim/init.vim#L297

Also, since prettier can now use stdin, I would suggest the following:

let g:neoformat_javascript_prettier = {
            \ 'exe': 'prettier',
            \ 'args': ['--stdin', '--single-quote'],
            \ 'stdin': 1,
            \ }

@sbdchd any reason to prefer using standard in?

[sbdchd]

@fortes

with stdin, buffer --> formatter --> buffer,

without stdin, buffer --> tmp_file <-- formatter --> buffer

There isn't any usability difference that I know of, but not having to write to a tmp file is a plus.

@sbdchd got it, I'll switch my config. Thanks.

Thanks @fortes @sbdchd! Closing 👍

@sbdchd Using your version, I now see Neoformat: attempted all formatters for current filetype when calling the plugin in a JavaScript buffer. If I switch back to my fork, it formats correctly. How would I go about debugging?

[aaronmcadam]

@sbdchd It seems to be enabling stdin for prettier that makes the plugin not see the formatter for me. I've reproduced it in my fork.

[sbdchd]

@aaronmcadam Have you updated prettier? Stdin is a relatively new option.

Otherwise, can you set verbose=1 before running :Neoformat and copy the output of :messages to here?

[aaronmcadam]

Hi @sbdchd

Yeah I've updated prettier to 0.0.5.

Here's the output when I turn :Neoformat:

If you run prettier with no arguments, do you get the following output?

Usage: prettier [opts] [filename ...]

Available options:
  --write              Edit the file in-place (beware!)
  --stdin              Read input from stdin
  --print-width <int>  Specify the length of line that the printer will wrap on. Defaults to 80.
  --tab-width <int>    Specify the number of spaces per indentation-level. Defaults to 2.
  --flow-parser        Use the flow parser instead of babylon
  --single-quote       Use single quotes instead of double
  --trailing-comma     Print trailing commas wherever possible
  --bracket-spacing    Put spaces between brackets. Defaults to true, set false to turn off

From your output of :Neoformat it appears you are on a version without stdin:

Usage: prettier [opts] [filename]  
Available options:   
--write              Edit the file in-place (beware!)   
--print-width <int>  Specify the length of line that the printer will wrap on. Defaults to 80.   
--tab-width <int>    Specify the number of spaces per indentation-level. Defaults to 2.   
--flow-parser        Use the flow parser instead of babylon   
--single-quote       Use single quotes instead of double   
--trailing-comma     Print trailing commas wherever possible   
--bracket-spacing    Put spaces between brackets. Defaults to true, set false to turn off

[aaronmcadam]

Yeah, that's what it looks like, but running prettier outputs:

❯ prettier
Usage: prettier [opts] [filename ...]

Available options:
  --write              Edit the file in-place (beware!)
  --stdin              Read input from stdin
  --print-width <int>  Specify the length of line that the printer will wrap on. Defaults to 80.
  --tab-width <int>    Specify the number of spaces per indentation-level. Defaults to 2.
  --flow-parser        Use the flow parser instead of babylon
  --single-quote       Use single quotes instead of double
  --trailing-comma     Print trailing commas wherever possible
  --bracket-spacing    Put spaces between brackets. Defaults to true, set false to turn off

[sbdchd]

Hmm. Can you try removing all versions of prettier and then reinstall prettier.

For some reason :Neoformat is accessing an older version without --stdin, which is odd.

[aaronmcadam]

@sbdchd I managed to sort it, my global node was set to the wrong version. I'd been tinkering with my nvm setup. Sorry for the confusion!!
