Small cleanup for code sharing. Note, `*ReadFile` will trigger a CHECK-failure on error; the relevant implementations would previously have failed silently (empty string). --------- Co-authored-by: Richard Smith <richard@metafoo.co.uk>

# See README.md for instructions on tree-sitter setup and use. These rules are
|
|
# manual because the tree-sitter invocation is non-hermetic, and most developers
|
|
# won't have it installed; we don't want to break "bazel test //..." if we can
|
|
# avoid it.
|
|
#
|
|
# We use tree-sitter non-hermetically for two key reasons:
|
|
#
|
|
# - The main way of hermetically using npms in bazel, `aspect_rules_js`, uses
|
|
# declare_symlink; we disallow that for important compatibility reasons.
|
|
# - When generated, src/parser.c is over 500 KB, which is larger than we want to
|
|
# check in. It should also be expected to grow if the grammar becomes more complete.
|
|
|
|
# Convenience target for running all tests, including manual tests.
