dddlint¶

Polyglot ubiquitous language linter for codebases and coding agents.

dddlint reads class, function, method, and type names across 306 languages and enforces them against a domain vocabulary: banned terms, non-canonical synonyms, and one concept spelled several ways.

It works with any language tree-sitter recognises, without per-language queries. It slots into pre-commit hooks, CI pipelines, and coding-agent loops via a non-zero exit code on findings, and ships an LSP server for inline editor diagnostics with rename code actions.

The idea in one example¶

A team agrees order is the canonical term. Someone commits a process_transaction method. dddlint flags it in CI, in a commit hook, or right in the editor, and suggests the rename to process_order.

synonyms:
  - canonical: order
    aliases: [purchase, transaction]
forbidden: [util, helper, manager]

Beyond spelling¶

Token rules only catch the words you thought to write down. dddlint map embeds every definition name and compares meaning instead, so fetch_order and retrieve_purchase surface as the same idea worded twice even though they share no token, and a name whose vocabulary belongs to another bounded context gets flagged where it sits.

dddlint map src/

Every run also draws the whole vocabulary, one boundary per bounded context:
