* Optimize parsing of rangesLibravatar René Kijewski2022-01-061-17/+13
| | | | | | | | | | Right now almost every expression needs to be parsed twice: `expr_any()` first parses the left-hand side of a range expression, and if no `..` or `..=` was found the left-hand expression is parsed again, this time as the result of the function. This diff removes the second parsing step by first looking for `.. (opt rhs)`, then for `lhs .. (opt rhs)`.

* Simplify take_content() implementationLibravatar René Kijewski2021-11-241-43/+37
|
* Parse `&str` instead of `&[u8]`Libravatar René Kijewski2021-11-241-132/+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.
* Simplify identifier() implementationLibravatar René Kijewski2021-11-241-17/+15

* Simplify ws() and split_ws_parts()Libravatar René Kijewski2021-11-241-43/+19

* Implement `for … in … if …`Libravatar René Kijewski2021-11-111-1/+6
|
* Implement for-elseLibravatar René Kijewski2021-11-111-9/+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 %} ```
* Use char() instead of tag() when possibleLibravatar René Kijewski2021-10-121-73/+76

* Ensure that {%break%} is only used inside of a loopLibravatar René Kijewski2021-08-301-46/+76
|
* Add {% break %} and {% continue %}Libravatar René Kijewski2021-08-301-0/+16
| | | | | This PR adds `{% break %}` and `{% continue %}` statements to break out of a loop, or continue with the next element of the iterator.
* Parse boolean literals in assignment targetsLibravatar René Kijewski2021-08-251-3/+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.

* Better error messages using cutsLibravatar René Kijewski2021-07-301-131/+186

* Use "target()" to parse "when" blockLibravatar René Kijewski2021-07-301-150/+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.
* Allow omitting "with" keyword in match blocksLibravatar René Kijewski2021-07-301-1/+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.
* Allow using "with" keyword in "let" statementsLibravatar René Kijewski2021-07-301-0/+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.
* Implement destructoring of structsLibravatar René Kijewski2021-07-051-6/+42
| | | | | This PR implements the destructoring of structs on the lhs of "let" and "for" statements.
