2021-11-24Parse `&str` instead of `&[u8]`Libravatar René Kijewski1-132/+120
Askama's takes valid UTF-8 files as input. So why operate on byte slices instead of strings? This makes writing some functions a lot simpler.

2021-11-11Implement `for … in … if …`Libravatar René Kijewski1-1/+6
2021-11-11Implement for-elseLibravatar René Kijewski1-9/+40
This PR implements for-else statements like in Jinja. They make it easy to print an alternative message if the loop iterator was empty. E.g. ```rs {% for result in result %} <li>{{ result }}</li> {% else %} <li><em>no results</em></li> {% endfor %} ```

2021-08-30Ensure that {%break%} is only used inside of a loopLibravatar René Kijewski1-46/+76
2021-08-30Add {% break %} and {% continue %}Libravatar René Kijewski1-0/+16
This PR adds `{% break %}` and `{% continue %}` statements to break out of a loop, or continue with the next element of the iterator.
2021-08-25Parse boolean literals in assignment targetsLibravatar René Kijewski1-3/+21
268d825 introduced a regression that made matching against boolean literals impossible. E.g. "true" was interpreted as the variable "r#true". This PR fixes the problem. The bug was reported by @Restioson in issue #531.

2021-07-30Use "target()" to parse "when" blockLibravatar René Kijewski1-150/+40
`target()` as used in parsing "let" and "if let" implements parsing nested tuples and structs. But it does not implement parsing literals. The functions `match_variant()` and `with_parameters()` as used in parsing "when" blocks do not implement parsing nested structs, but it implements parsing literals. This PR combines `match_variant()` and `with_parameters()` into `target()`, so that all `{%when%}` support nested structs, too.
2021-07-30Allow omitting "with" keyword in match blocksLibravatar René Kijewski1-1/+1
Askama uses the syntax `{% when Variant with (parameters) %}` in `{% match %}` blocks. This is done because Askama does not implement the whole pattern matching of Rust's `match` statements. This PR wants to bring Askama a step closer Rust's matching, so the "with" keyword should not be needed anymore.
2021-07-30Allow using "with" keyword in "let" statementsLibravatar René Kijewski1-0/+1
Askama uses the syntax `{% when Variant with (parameters) %}` in `{% match %}` blocks. This change allows the optional use of the keyword "with" in "let" and "if let" statements, too.
2021-07-05Implement destructoring of structsLibravatar René Kijewski1-6/+42
This PR implements the destructoring of structs on the lhs of "let" and "for" statements.

* 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.
