Description: The diff computation algorithm in this project is a C port of VSCode's defaultLinesDiffComputer implementation. The algorithm, data structures, and optimization heuristics are derived from VSCode's TypeScript source code.
Key Components Ported:
- Myers diff algorithm (
src/vs/editor/common/diff/defaultLinesDiffComputer/algorithms/myersDiffAlgorithm.ts) - Dynamic Programming algorithm (
src/vs/editor/common/diff/defaultLinesDiffComputer/algorithms/dynamicProgrammingDiffing.ts) - Line-level optimization heuristics (
src/vs/editor/common/diff/defaultLinesDiffComputer/heuristicSequenceOptimizations.ts) - Character-level refinement (
src/vs/editor/common/diff/defaultLinesDiffComputer/defaultLinesDiffComputer.ts) - Range mapping data structures (
src/vs/editor/common/diff/rangeMapping.ts)

Source: https://github.com/neovim/neovim
Location: lua/vscode-diff/render/semantic_tokens.lua (lines 38-117)
Description: Two helper functions from Neovim's LSP semantic tokens implementation are vendored because there is no public API to process semantic token responses for arbitrary buffers.
Functions Vendored:
modifiers_from_number()- Decodes token modifiers from bit fieldtokens_to_ranges()- Converts LSP token array to highlight ranges
Reason for Vendoring: Neovim's LSP semantic token API is designed for regular buffers only. Virtual/scratch buffers need direct access to the parsing functions, which are not publicly exported.
