2023-09-28Pass `Node` parsing level to expressionsLibravatar René Kijewski1-2/+2
2023-09-28Limit nesting in parser nodes, tooLibravatar René Kijewski2-0/+129
2023-07-31 Fix parsing arraysLibravatar René Kijewski2-7/+3
This change * allows using empty arrays `[]` in expessions, * adds a cut when the leading `[` was encountered, and * fixes the interaction between arrays and boolean OR. IMO the restriction that you couldn't use empty arrays is not needed. The missing cut made error messages slictly worse if you forget to add the closing `]`. Filter expressions must not have white spaces before the pipe `|`. The white space is used to tell a filter expressions, and `std::ops::Or` apart.

2023-07-24Fix Rust macro invocations not accepting a path (#837)Libravatar Matthew Taylor2-2/+23
2023-06-12Allow macros to be defined and called without argumentsLibravatar mataha2-0/+31
This commit introduces a shorthand for defining and calling macros when using them as a reusable substitute for variables assigned complex values (e.g. string literals with or without newline escapes). The use-case is formatting - from my experience it's easier to visually parse a `macro` `endmacro` block than a multiline variable assignment. Signed-off-by: mataha <mataha@users.noreply.github.com>

In <https://github.com/dtolnay/trybuild/pull/219> the output of error messages was subtly changed, because they introduced a subdirectoy in their temp path. This PR fixes the mismatch between the expected and the actual output.

I was going through the book when I saw the version was still 0.8. This commit ensures all references to Askama version are to 0.11.2. Most of them already were. Merge whenever appropriate for release, #722 related

2022-07-25Remove support for deprecated `_parent` fieldLibravatar René Kijewski1-4/+40
The support for the magic `_parent` field is deprecated since v0.8.0 or issue #180. It's bothersome to keep this feature alive, when no-one should be using it for 3 years.

2022-04-29Allow `{% endmacro name %}`Libravatar Bastien Orivel2-1/+13
Just migrated a repo from tera to askama and this was one of the only things that was different. This is also coherent with `{% block %}` for which I added the same feature years ago.

2022-02-16Make json filter safeLibravatar René Kijewski3-2/+64
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.

2022-01-31Use exact trybuild versionLibravatar René Kijewski1-1/+1
Sometimes for no obvious reason an old version is selected and the output is different in just about every ui test. Just pin it to the currently newest version and test if an updated version still works when a new version gets released.

2022-01-28Parse tuple expressionsLibravatar René Kijewski1-0/+82
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 Kijewski1-0/+69
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 Kijewski1-0/+82
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`.

2021-12-15Use a separate trait for object safety (#579)Libravatar Dirkjan Ochtman2-11/+8
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...

2021-11-11Implement for-elseLibravatar René Kijewski1-0/+19
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 %} ```

This PR adds `{% break %}` and `{% continue %}` statements to break out of a loop, or continue with the next element of the iterator.
