prettier not running

[jgwinner]

Hi

I downloaded the extension, install it, configured it in VStudio to run on save:

then setup the .multilinterrc.json file as in your example:

{
  "eslint": {
    "enabled": true,
    "additionalArguments": "",
    "fileExtensions": "js"
  }
}

Works great.

About to lint by:

              Linter: "eslint"
   Current Directory: "C:\c\cover\workhub\"
        Command line: "C:\c\cover\workhub\node_modules\.bin\eslint.cmd"
           Arguments: ""nuxt.config.js" -f json"

I then try prettier, by changing the .multilinterrc.json but it never runs:

Searching linters to be used for file extension ".json"
No linters found to be used for file extension "json"

Odd. My package.json has:

  "devDependencies": {
    "@nuxtjs/eslint-config": "^1.0.1",
    "@nuxtjs/eslint-module": "^1.0.0",
...
    "eslint": "^6.1.0",
    "eslint-config-prettier": "^4.1.0",
    "eslint-plugin-nuxt": ">=0.4.2",
    "eslint-plugin-prettier": "^3.0.1",
    "prettier": "2.3.1"
  },
...

Note that per the docs at: https://prettier.io/docs/en/install.html the command is yarn prettier, so I modified your setup:

{
  "prettier": {
    "enabled": true,
    "additionalArguments": "",
    "fileExtensions": "js",
    "executable": "yarn prettier"
  }
}

Now it thinks prettier is configured, BUT still won't run. Debug output:

Formatter Name = prettier

            Enabled = true
         Executable = "yarn prettier"
          Arguments = "--write "{filePath}""
     StdInArguments = "--stdin-filepath "{filePath}""
AdditionalArguments = ""
   InstallationType = "local"

... snip

eslint works fine.

Any ideas? I'm sure it's some other parameter is different from the seeded setup files and our setup, which I thought was fairly off the shelf. Prettier is mandated by the org.

It's because of "yarn prettier" executable. Multilinter searches for a "yarn prettier" executable up to the root. Of course it cannot find such file (which name should be "yarn prettier.exe/cmd/bat" and so it fails. Actually is only supported to launch those externals executable directly, such as prettier.exe/cmd/etc, not by using yarn. Sorry.

Prettier isn't a .exe, it's JS, so it has to be run via Node, i.e. npm or yarn. There is a .CMD though, which includes that, so I'm getting closer with this, but {filename} isn't expanding.

That's got to be a bug.

{
  "prettier": {
    "enabled": true,
    "additionalArguments": --write "\"{filePath}\"  ",
    "fileExtensions": "js,vue",
    "executable": "prettier.cmd",
    "StdInArguments": ""
  }
}

gives me this error:

Formatters found to be used for file extension ".vue" found: prettier,

About to format by:

           Formatter: "prettier"
   Current Directory: "C:\c\stuff\"
        Command line: "C:\c\stuff\node_modules\.bin\prettier.cmd"
           Arguments: ""{filePath}" --write"

Error:

[error] No files matching the pattern were found: "{filePath}".

If I include {filename} in the StdInArguments it works fine, but replaces my file with the timing of the results. No other combination of {filename} or \"{filename}\" ever worked. It works fine from the command line.

So, I tried:

  "prettier": {
    "enabled": true,
    "additionalArguments": "--parser vue",
    "fileExtensions": "js,vue",
    "executable": "prettier.cmd",
    "StdInArguments": "\"{filePath}\""
  }
}

This locks up visual studio. Had to kill it with the task manager.

Third (tieth) try is the charm, this works:

{
  "prettier": {
    "enabled": true,
    "additionalArguments": "",
    "fileExtensions": "js,vue",
    "executable": "prettier.cmd",
    "StdInArguments": "--parser vue"
  }
}

Because I am using the 'standard' Prettier with an off the shelf install, I think the above settings should be the default in .MultiLiter, or at least documented.

So, it's now working!

Whoops - it broke Javascript

[glat]

So is it working now? Also, because the base config for prettier is:

{ "prettier": { "enabled": false, "additionalArguments": "", "fileExtensions": "", "executable": "prettier.cmd", "arguments": "--write \"{filePath}\"", "stdInArguments": "--stdin-filepath \"{filePath}\"", "installationType": "local", "toolType": "formatter" } }

When you want to add a stdInArgument you should add the string to the string in the base config. So you should write:

{ "prettier": { "enabled": true, "additionalArguments": "", "fileExtensions": "js,vue", "executable": "prettier.cmd", "stdInArguments": "--stdin-filepath \"{filePath}\" --parser vue" } }

But I think you can also use:

{ "prettier": { "enabled": true, "additionalArguments": "--parser vue", "fileExtensions": "js,vue" } }

Let me know.

Ok, I'll try those, thanks.

The only problem with "--parser vue" was that it broke Javascript, so I could use a different linter that's supposed to do prettier with .js, as the original problem was that one didn't do .vue files. Your add-in does, and it's about the only one. What was weird, is that prettier didn't seem to do .vue files unless I added the --parser vue.

I'll fiddle with it some more. At least now, between the standard linter and your adding, I can get Nuxt to compile and run! Our project upgraded from a 1.x of Prettier to a 2.3.X, which broke a bunch of stuff.
