2021-12-15Use a separate trait for object safety (#579)Libravatar Dirkjan Ochtman1-17/+5
This is relatively major change to the main trait's API. For context, I always started from the concept of monomorphized traits, but later several contributors asked about object safety. At that point I made `Template` object-safe, and then even later added a `SizedTemplate` to make some things easier for people who don't need object safety. However, having object-safety in the primary trait is bad for performance (a substantial number of calls into the virtual `Write` trait is relatively slow), and I don't think those who don't need object safety should pay for the cost of having it. Additionally, I feel using associated consts for the extension and size hint is more idiomatic than having accessor methods. I don't know why I didn't use these from the start -- maybe associated consts didn't exist yet, or I didn't yet know how/when to use them. Askama is pretty old at this point...

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-elseLibravatar René Kijewski3-29/+72
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 %} ```

2021-08-30Add {% break %} and {% continue %}Libravatar René Kijewski2-0/+26
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 Kijewski2-3/+27
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 Kijewski3-253/+83
`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.

This PR implements the destructoring of structs on the lhs of "let" and "for" statements.

2021-07-05Reduce code duplication for writing targetsLibravatar René Kijewski1-22/+9
This change also fixes a bug in the loop generator, which failed for shadowed variables.

2021-07-05Remove duplicated code in generatorLibravatar René Kijewski1-17/+1
2021-07-05Prepare generator::visit_target() for nested targetsLibravatar René Kijewski1-4/+2
By now only non-nested tuples are accepted by the parser, but this will change. This change makes visit_target() call itself for items in a tuple. So enable the function to call itself, I needed to fix the lifetime annotation, because the references inside a Target instance may outlife a reference to instance itself.
