pytorch/pytorch: which of 57 linter adapters become rules

PyTorch built lintrunner to run the 57 linter adapters in .lintrunner.toml, 24 of them regex searches. The config ports the regex ones it can, runs the formatters from command_idempotent rules and leaves the adapters that parse Python or C on lintrunner.This config was written to test alint; PyTorch doesn't use alint.

The config

The config ports regex adapters as content rules, such as the bans on std::call_once and on unpinned pip installs. The formatter adapters run from command_idempotent rules, which fail when a formatter would change a file. It also checks the code generator's output and the generated workflows.

.alint.yml

- id: pytorch-no-std-call-once
  # fixed here: the same paths as the lintrunner adapter
  kind: file_content_forbidden
  paths: { include: ["c10/**","aten/**","torch/csrc/**","torch/nativert/**"], exclude: ["c10/util/CallOnce.h","**/fb/**"] }
  pattern: 'std::call_once'
  level: warning

One of the regex adapters from grep_linter.py, as a content rule: PyTorch's C++ uses its own call-once helper instead of std::call_once.

.alint.yml

- id: pytorch-pypi-install-must-be-pinned
  # fixed here: (?m), so $ ends each line as it does for grep
  kind: file_content_forbidden
  paths:
    include: [".github/**"]
    exclude: ["**/*.rst","**/*.py","**/*.md","**/*.diff","**/fb/**"]
  pattern: '(?m)(pip|pip3|python -m pip|python3 -m pip|python3 -mpip|python -mpip) install ([a-zA-Z0-9][A-Za-z0-9._\-]+)([^/=<>~!]+)[A-Za-z0-9._\-*+!]*$'
  level: error

Another: every pip install in the workflows names an exact version.

What stays outside alint

Adapters that parse code or compare jobs stay on lintrunner:

the adapters that parse Python or C or compare version ranges, such as the docstring, test-main and device-bias checks, the graph-break registry and the stable-shim checks;
clang-tidy and pyrefly, which do their own analysis; alint only runs them;
WORKFLOWSYNC, which compares every job with every other job that shares its tag. cross_file compares one source with its targets;
two adapters that need rule kinds alint doesn't have: blank lines between CSV rows, and a repository-owner guard on workflows that run on push or pull request.
