Git

Git never leaves the editor — the main operations, and you can peek under the hood of history without taking your hands off the buffer:

Видео «blame» не найдено (урок не готов или slug неверный).

Видео «staging» не найдено (урок не готов или slug неверный).

Видео «log» не найдено (урок не готов или slug неверный).

Видео «review» не найдено (урок не готов или slug неверный).

Errors can also be shown with taste rather than as a sheet across half the screen.

In lazyvim: cd

A small floating window with the diagnostic pops up under the cursor — exactly the place where everything came apart.

We jump between diagnostics with ]d, [d

The same for ]e (errors), ]w (warnings)

All the file's errors at once — Trouble, opened with xx. Inside Trouble we press K, and a multi-line error expands in full. Diagnostics are toggled back and forth with ud

Testing

The test config is in place — open a test file: a single test runs with tr, the whole file with tt.

We click the results summary with to.
