Structural diffs, deep static analysis and navigation back to the code.

config.ts · structural
The structural diff of src/config.ts. The file was formatted again and one field was added. One line has a change mark: tags: string[]. The header shows +1 −0.
The line diff of the same change. Two lines are marked as removed and twelve lines as added. The header shows −2 +12.

Structural diff

Change map

The side bar lists the symbols that changed, not the files. Each row has the class of its change.

Navigation

Oaink
The change map in the side bar of VS Code. One pull request is open. Its symbols are in two groups. Each row has a checkbox, the name of the symbol, its added and removed lines, and a two-letter class.
Fig. 5 · Change map ·HC Ebony
sg
The signature changed.
bd
The body changed.
nw
The symbol is new.
rm
