Plugin Version

3.2.0

Prettier Version

3.3.3

Which frameworks are affected?

  • none
  • vue
  • angular
  • svelte

Node Version

21.7.2

Which operating systems have you used?

  • Linux
  • macOS
  • Windows

Prettier config

exportdefault{plugins: ["@prettier/plugin-pug"],htmlWhitespaceSensitivity: "css",printWidth: 80,arrowParens: "avoid",bracketSameLine: false,semi: true,tabWidth: 2,useTabs: false,endOfLine: "auto",trailingComma: "es5",vueIndentScriptAndStyle: false,pugAttributeSeparator: "as-needed",pugFramework: "vue",};

Input

h2 Link: a(href="") Click

note trailing space "Link: "

Output or Error

h2 Link:
|
a(href="") Click

note trailing space is removed "Link:" and pipe doesn't have it either!

Expected Output

h2 Link:
| a(href="") Click
//- or perhaps h2
| Link:
|
a(href=“”) Click

note trailing space after pipe "| " - the intended behavior

OR

Probably better move the text into child pipe and insert an extra pipe for that space

Additional Context

Prettier alters the result of the template which is not intended. Please look at https://pugjs.org/language/plain-text.html#whitespace-control

Also it doesn't respect htmlWhitespaceSensitivity: "strict" option and still removes any extra whitespace

                      a(href=“”) Click

                      note trailing space after pipe "| " - the intended behavior

                      OR

                      Probably better move the text into child pipe and insert an extra pipe for that space

                      Additional Context

                      Prettier alters the result of the template which is not intended. Please look at https://pugjs.org/language/plain-text.html#whitespace-control

                      Also it doesn't respect htmlWhitespaceSensitivity: "strict" option and still removes any extra whitespace
