Similar to #323, I'm okay with the code generator changes but let's only have a specific test that tests some subset of the code generator for whitespace sensitivity. |
This was referenced May 25, 2020
* in function calls: `x ( 1 , 2 )`; * in path elements: `module :: element`; * in attributes: `x . y . z`; * in filter arguments: `x| filter ( 1 , 2 )`; * before unary operators: `! false` and `- 42`; * in grouped expressions: `( 1 + 2 )`; * also allow more than a single whitespace; Change some tests to include whitespaces in various positions.

As reported in #315 at the moment whitespaces aren't allowed in many places where normal Rust would allow them.
This pull request adds support for whitespaces in:
x ( 1 , 2 );module :: element;x . y . z;x| filter ( 1 , 2 );! falseand- 42;Also change some tests to include whitespaces in various positions.
As noted in #315 at the moment there is a language ambiguity regarding bitwise or and filter application. As such at the moment the pipe character
|should not be preceded by a space when wanting filter application, and must always be preceded when wanting bitwise or. (This is not a deficiency of the current patch.)
