Support line-based comment.

Jinja2 support line comment, does minijinja will support it?

[mitsuhiko]

Yes, if you enable the custom_syntax feature you can configure line comments:

use minijinja::{context, syntax::SyntaxConfig, Environment};

let mut env = Environment::new();
env.set_syntax(
    SyntaxConfig::builder()
        .line_statement_prefix("#")
        .line_comment_prefix("##")
        .build()
        .unwrap(),
);

Why isn't this functionality built in?

[cathaysia]

oh, sorry, I missed this:

[mitsuhiko]

It is built in. You just need to enable the feature flag. Like you noticed in neither Jinja2 nor minijinja is it enabled by default.
