2022-04-21Rename `suppress_whitespace` into `whitespace` and update expected values to ↵Libravatar Guillaume Gomez2-19/+55
"suppress" and "preserve"

2022-03-31Add io::writer helper methodsLibravatar René Kijewski1-2/+20
It might not be immediately obvious to everyone how easy it is to use Askama template with std::io (e.g. files) instead of std::fmt, so this PR adds a few helper methods to make this more obvious to novice users.
2022-03-31Expose the fact that templates implement DisplayLibravatar René Kijewski1-2/+21
This is a quite useful feature, because you can use templates in format!(), format_args!(), etc.
2022-03-30Move Template into askama_shared, tooLibravatar René Kijewski1-0/+88
The traits Template and DynTemplate need to be in sync with askama_shared's generator. #647 consolidated the template crating into askama_shared, this PR moves the trait itself.
2022-03-28Implement std::error::Error::sourceLibravatar René Kijewski1-4/+4
Error::cause() is deprecated since Rust 1.33.

2022-03-23Merge derive.rs into generator.rsLibravatar René Kijewski3-119/+100
2022-03-23Un-"pub" most of askama_shared's internalsLibravatar René Kijewski6-81/+81
Previously askama_shared exported most of it's internals, so askama_derive could use them. This is not needed anymore.
2022-03-23Reduce askama_derive to a single re-exportLibravatar René Kijewski2-0/+107
All the hard work in askama_derive was actually done in askama_shared. This PR removes the back-and-forth interaction between the two crates. Now askama_derive is a single re-export of `#[derive(Template)]` which has to be done in a proc_macro crate. This most likely means that askama_derive is "final", unless another derive template needs to be introduced in the future.
2022-03-23Move handling of integrations into askama_sharedLibravatar René Kijewski2-50/+27
Before this PR the handling of integrations was done both by askama_shared and askama_derive. This diff lets askama_shared do the work. This will prevent problems like #629, when both packages might come out of sync.

2022-02-16Make json filter safeLibravatar René Kijewski2-17/+24
Previously the built-in json filter had an issue that made it unsafe to use in HTML data. When used in HTML attributes an attacker who is able to supply an arbitrary string that should be JSON encoded could close the containing HTML element e.g. with `"</div>"`, and write arbitrary HTML code afterwards as long as they use apostrophes instead of quotation marks. The programmer could make this use case safe by explicitly escaping the JSON result: `{{data|json|escape}}`. In a `<script>` context the json filter was not usable at all, because in scripts HTML escaped entities are not parsed outside of XHTML documents. Without using the safe filter an attacker could close the current script using `"</script>"`. This PR fixes the problem by always escaping less-than, greater-than, ampersand, and apostrophe characters using their JSON unicode escape sequence `\u00xx`. Unless the programmer explicitly uses the safe filter, quotation marks are HTML encoded as `&quot`. In scripts the programmer should use the safe filter, otherwise not.

2022-01-28Parse tuple expressionsLibravatar René Kijewski2-3/+163
Askama understands how to destructure tuples in let and match statements, but it does not understand how to build a tuple. This PR fixes this shortcoming.
2022-01-28 Implement error propagation expression: `?` (#590)Libravatar René Kijewski3-6/+30
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.
2022-01-27Unify handling of calls (#614)Libravatar René Kijewski2-145/+157
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`.
2022-01-24Replace `&PathBuf` with `&Path`Libravatar René Kijewski2-9/+9
PathBuf is to String like Path is to str, so `&PathBuf` is a pointer to a pointer. Clippy does not likes that.

2022-01-12Add template argument for contexts' hasherLibravatar René Kijewski1-2/+2
In askama_shared::generate a custom hasher for the contexts can be given, so Heritage needs to accept the argument to.

2022-01-06Optimize parsing of rangesLibravatar René Kijewski1-17/+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)`.
2022-01-06Add `#[inline]` to trivial trait implementationsLibravatar René Kijewski1-0/+9
2022-01-06Remove the iron integration from generatorLibravatar René Kijewski2-27/+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.
