git

name	git
description	Show uncommitted changes and commit history via git. Use when: (1) inspecting what changed in a file before committing, (2) checking diff of tracked/new/deleted files, (3) reviewing a specific commit's changes, (4) listing files changed in a commit.

Git

Use native, non-interactive git commands to inspect changes. Run them from the repository root and keep path lists explicit so unrelated user work stays out of a commit.

Inspect working-tree changes

git status --short
git diff --check
git diff --stat
git diff -- <tracked-file> [tracked-file ...]
git diff --no-index -- /dev/null <new-untracked-file>

Before committing, inspect every intended tracked file and every intended new file. Do not stage unrelated untracked files merely because they appear in git status.

Inspect commits

git show --stat --oneline <commit>
git show --format=fuller --find-renames <commit> -- <path> [path ...]
git diff <commit>^ <commit> -- <path> [path ...]

For a root commit, use git show <commit> because <commit>^ does not exist. Use git diff --name-status when only the changed-file inventory is needed.

update_sha256 — DX SDK zip update

Update DX SDK zip name and SHA256 across all files that reference it, via scripts/update_sha256.py.

python scripts/update_sha256.py [zip_name]

Behavior

Arg	Effect
zip_name given	Uses SDKs/<zip_name> as the local zip; must exist.
zip_name omitted	Parses zip name from LUISA_COMPUTE_DX_SDK in scripts/sdks.cmake.

Computes SHA256 of the local zip, then updates:

File	What changes
scripts/sdks.cmake	LUISA_COMPUTE_DX_SDK (URL + SHA256 as one CMake list)
scripts/find_sdk.lua	name field under dx_sdk entry

Examples

# Provide zip name explicitly
python scripts/update_sha256.py dx_sdk_20260622.zip

# Auto-detect from CMakeLists.txt URL
python scripts/update_sha256.py

Notes

• Zip must live under SDKs/ relative to repo root.
• Skips files not found with a warning (non-fatal).
• No-op if all values are already up-to-date.
