Struct LintConfig 

pub struct LintConfig {
    pub rules: BTreeMap<String, Level>,
    pub strict: Option<bool>,
}

[lint] — which rules run at what level, and whether what they report stops the run.

The two keys are the same question at two grains: rules names one rule, strict promotes every warn of a run at once.

Fields

rules: BTreeMap<String, Level>

[lint.rules] — the level of each rule this project has an opinion about.

A key is any entry of crate::lint::RULES — one of htl’s own rules, or one of the vendored Teal compiler’s warning kinds under its tl: prefix ("tl:hint", "tl:unused", …, which have to be quoted because : is not a bare TOML key). htl check --list-lints prints them all with their defaults. A value is "allow", "warn" or "deny". An unknown name or level is refused rather than ignored: a typo that turned nothing on would read exactly like a rule that found nothing, and a misspelt "deny" would read like a run that passed.

One place per rule says everything about that rule. The enable / disable lists this replaced said it in two places that had to be read together, and neither could say what a rule was worth. A rule this table does not name keeps its default level.

strict: Option<bool>

true: every finding this run reports at warn counts as deny, so Teal’s warnings and htl’s lints fail htl check; lints also fail include_tl! (the macro reports Teal’s warnings and builds anyway). false: advisory everywhere (including the macro, whose built-in default is strict), except for a rule the project set to deny, which fails htl check with or without this key.

A run-wide promotion rather than a concept of its own: strict and a [lint.rules] level are the same question asked at two grains.

htl test does not read it, by design: a test run’s verdict is its tests, plus the type errors that stop a file from running at all. Warnings and lints are still reported there; htl check is where they are judged.
