* Implement error propagation expression: `?` (#590)Libravatar René Kijewski2022-01-281-0/+12
| | | | | | This change allows using the operator `?` in askama expressions. It works like the same operator in Rust: if a `Result` is `Ok`, it is unwrapped. If it is an error, then the `render()` method fails with this error value.
* Unify handling of calls (#614)Libravatar René Kijewski2022-01-271-79/+31
| | | | | Instead of having `Expr::VarCall`, `Expr::PathCall` and `Expr::MethodCall`, this PR unifies the handling of calls by removing the former three variants, and introducing `Expr::Call`.
* Replace `&PathBuf` with `&Path`Libravatar René Kijewski2022-01-241-7/+7
| | | | | PathBuf is to String like Path is to str, so `&PathBuf` is a pointer to a pointer. Clippy does not likes that.

* Remove the iron integration from generatorLibravatar René Kijewski2022-01-061-26/+0
| | | | | | | Issue #527 removed the askama_iron package, but not the integration if someone uses askama_derive's feature with "iron". The old askama_iron crate uses askama v0.10, so it will still work.

* Use a separate trait for object safety (#579)Libravatar Dirkjan Ochtman2021-12-151-17/+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...

|
* Implement for-elseLibravatar René Kijewski2021-11-111-17/+26
| | | | | | | | | | | | | 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 %} ```

|
* Add {% break %} and {% continue %}Libravatar René Kijewski2021-08-301-0/+10
| | | | | 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 Kijewski2021-08-251-0/+6
| | | | | | | | 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.
* Use "target()" to parse "when" blockLibravatar René Kijewski2021-07-301-102/+42
| | | | | | | | | | | | `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.
* Implement destructoring of structsLibravatar René Kijewski2021-07-051-2/+17
| | | | | This PR implements the destructoring of structs on the lhs of "let" and "for" statements.
* Parse nested tuples in "let" statement lhsLibravatar René Kijewski2021-07-051-3/+3
|
* Reduce code duplication for writing targetsLibravatar René Kijewski2021-07-051-22/+9
| | | | | This change also fixes a bug in the loop generator, which failed for shadowed variables.
* Move logic where target shadows or declares a variable into methodLibravatar René Kijewski2021-07-051-23/+33

* Remove duplicated code in generatorLibravatar René Kijewski2021-07-051-17/+1
|
* Prepare generator::visit_target() for nested targetsLibravatar René Kijewski2021-07-051-4/+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.
