    Hello, I'm trying to make a macro with a default argument, but I get an error

    {% macro highlight_scripts(languages=["rust", "ini"]) %}
        ...
    {% endmacro highlight_scripts %}
    * Failed to parse "templates\\macros.html"
     --> 6:38
      |
    6 | {% macro highlight_scripts(languages=["rust", "ini"]) %}␊
      |                                      ^---
      |
      = expected an integer, a float, a string, or `true` or `false`

    Can macros not support all literal types?

    And is there a way to construct null values / what's the best way to do optional macro params

    Is it possible to call rust functions from within the templates? (currently calling {{ my_object.some_function() }} results in a template error :/)

    How do I select a Duration by Filename? I tried around a lot with filter but it doesn't seem to work for me because it expects a Vec.

    Help me because I have an urgent matter and a simple problem for someone experienced but I am just getting started with Actix with Tera and Rust. Tell me what to do when I copied this example
    https://github.com/actix/examples/tree/master/template_tera/
    I created a sample page.html file in the templates directory and in index.html file I added a menu and css file, in the menu I have link to the href = "page.html" file and of course css does not work and is correctly added and page.html does not open. CSS is correctly added because when I open index in browser CSS and menu works only when I start Actix it doesn't work :/ How to correctly add to Actix with Tera CSS and another HTML page to generate them correctly? Please show small example based on link from GitHub how I can correctly add CSS and another page in html.
    In dependencies I have lastest crates.

    Hey all, does tera have a way to render a bytes template? For example a template which is a Vec<u8> or &[u8]

    Does Tera have features that make it HTML5 specific? Would it be appropriate to use it for markdown or text templating?

    Taking a step back I am writing a cli (and later gui) that takes input to produce a text/md document. Looking at a possible rust (then flutter) implementation. I already use Zola and thanks to that am looking at Tera. Open to suggestions.

    Thanks in advance.

    Hi, I am trying to access the tera context values, but for some reason it does not work. I think the issue might be that the values contain dots. I tried for example this one: __tera_context.values["action_skills.skill0.points"] but it says

    Error: Variable `__tera_context.values["action_skills.skill0.points"]` not found in context while rendering 'macros': the evaluated version was `__tera_context.values.action_skills.skill0.points`. Maybe the index is out of bounds?"

    (I am using tera with rocket).

    The only way I can access them is {% for key, value in values %}, but this is a bit much just to get a single value... I already tried escaping the dots with a backslash, but no success so far. Any ideas what I am doing wrong?
