Navigate logical layers of code changes, visualize relationships, and explore their blast radius. WalkthroughThe SuperTOML language server adds go-to-definition support and quick-fix code actions. Diagnostics now provide codes and structured data for selected errors. New shared text helpers, tests, and VS Code examples support these features. ChangesSuperTOML LSP features

🎯 Functional Correctness | 🟠 Major | ⚡ Quick winMake diagnostic ranges cover the cursor positions for their quick fixes. LSP clients provide diagnostics that overlap the requested code-action range. The current ranges can exclude the cursor positions specified by the examples, so the corresponding actions receive no diagnostic. The tests mask this by passing every document diagnostic at every cursor position. (github.com)

In `@tooling/lsp/supertoml_lsp/src/code_actions.rs`:
- Around line 368-370: The insertion offsets in `code_actions.rs` use UTF-8 byte
counts where LSP positions require the negotiated encoding. Update the position
creation in the inline-table action and the new ranges in `value_after_key` and
`append_to_section` to convert byte offsets using the negotiated position
encoding, preserving the intended edit locations for non-ASCII text.
- Around line 269-271: Make the dimension edit-range lookup CRLF-aware: update
the offset calculations used by find_table_section_start and
find_key_assignment_range so they account for the actual line-ending byte width.
Preserve correct lookup behavior for both LF and CRLF documents, including later
dimension lines.
- Around line 64-65: Update the declaration generated by the code action to
infer its schema type from the dimension’s `_context_` value, reusing
`dimension_type_from_usage` as the missing-schema action does. Ensure a
dimension used with an integer context value is declared with an integer schema
rather than a string schema.
- Line 276: Update the position lookup used with value_after_key to find the
position assignment within the selected dimension entry, rather than the first
occurrence of “position” in the line. Construct the edit range from that member
so move or swap actions preserve the inline table declaration.
In `@tooling/lsp/supertoml_lsp/src/definition.rs`:
- Line 30: Convert `pos.character` from its LSP UTF-16 offset to a UTF-8 byte
offset before assigning `col` in the definition lookup flow. Use the source
line’s text for the conversion so comparisons with Rust string offsets,
including the marker lookup in `cohort_reference`, work correctly when earlier
characters are multibyte.
- Around line 83-89: Update cohort_reference so it first identifies the
dimension’s type string value, then searches that value for LOCAL_COHORT: or
REMOTE_COHORT: before extracting the dimension name. Do not match cohort markers
elsewhere on the line, such as in a config value.

Problem
The SuperTOML LSP documented Go to Definition and Code Actions but never implemented them — editors got
Method not foundfor both. Diagnostics also carried no machine-readable code, so nothing could attach afix to an error.
Solution
textDocument/definition: jump from a_context_dimension, an override key, or aLOCAL_COHORT:/REMOTE_COHORT:reference to its declaration.textDocument/codeAction: six quick fixes — declare a missing dimension, declare a missing config key, replace an invalid enum value, add an absentschema, resolve a duplicate dimension position, swap acohort dimension against its base.
