We've been hoping that mkdocs-material will ship the much anticipated search enhancements for some time, but it's time to recognize that we need to do something to improve the search results with how things work right now. This is a big commit that changes the titles of the various pages from the code-annotated synopsis to just the name of the function. This makes it much easier now to match things like `kumo.reject` directly, but `reject` remains awkward to find. I think this is the best that we can do at this time. A few functions have been annotated with the `status: deprecated` to show as deprecated in the toc/nav (shows with a little trash can next to the name).

# kumo.string.eval_template
|
|
|
|
```lua
|
|
kumo.string.eval_template(NAME, SOURCE, CONTEXT)
|
|
```
|
|
|
|
{{since('2025.03.19-1d3f1f67')}}
|
|
|
|
Evaluates a minijinja template.
|
|
|
|
The parameters are:
|
|
|
|
* `NAME` - the nominal "file name" for the template. No actual file I/O is
|
|
performed; this parameter tells the template engine what the filename would
|
|
have been if it were loaded from disk. The filename is used to decide what
|
|
strategy should be used for automatic output escaping. For example, if the
|
|
name ends with `.json` or `.html` then appropriate json or html entity
|
|
escaping will automatically be applied to the output.
|
|
* `SOURCE` - the template source code. This must follow the [template syntax](../template/index.md).
|
|
* `CONTEXT` - an object that defines the variables that are available to the template engine.
