Add escape hatch

prettier at this point is still outputting invalid JavaScript or badly formatted output in many cases. This will go down as time goes but in the meantime, it would be great to be able to disable it for just an expression.

Proposal:

// prettier-ignore-next-block
function a() { 
  iCanDoWhateverIdent
    (a, b,); }

and prettier will keep the next AST node as is.

@jlongster could follow ESLint’s example:

/* prettier-disable */
matrix(
  1, 0, 0,
  0, 1, 0,
  0, 0, 1
)
/* prettier-enable */

EDIT: Alternatively:

// prettier-ignore-next-statement
matrix(
  1, 0, 0,
  0, 1, 0,
  0, 0, 1
)

Because it’s being run through an AST, statements should be easy to isolate regardless of formatting.

i keep googling this and ending up here despite good documentation for it existing: https://prettier.io/docs/en/ignore.html

in case it’s helpful for other folks coming across this, the current way to do this is with a comment of prettier-ignore, e.g.

// prettier-ignore
matrix(
  1, 0, 0,
  0, 1, 0,
  0, 0, 1
)
