moongrep
moongrep is an experimental MoonBit structural search and taint-analysis tool.
Matching rules are declared as YAML files.
Scan
Run the scanner with a rule directory and an optional scan target directory or
.mbt file:
moon runwasm moonbit-community/moongrep -- scan --rules path/to/rules path/to/srcSynopsis:
moon runwasm moonbit-community/moongrep -- scan (--rules <rules-root> | --rules=<rules-root> | -r <rules-root>) [scan-root]The scanner is available through the scan subcommand. --rules / -r is
required. The long option accepts both --rules <rules-root> and
--rules=<rules-root> forms. One optional positional scan-root may appear in
the scan argument list and defaults to .. If the rules option appears
multiple times, the last value wins. Usage errors print a message and exit with
code 2: missing scan command, missing rules option, missing rules value,
unknown options, or more than one scan root. Non-usage errors, including
unreadable paths, an empty rules directory, invalid YAML/schema/shape, or source
read failures, abort the run; the CLI prints the error and exits with code 1.
If scan-root is omitted, moongrep scans the current directory:
moon runwasm moonbit-community/moongrep -- scan --rules path/to/rules
moon runwasm moonbit-community/moongrep -- scan -r path/to/rulesThe scanner recursively reads .mbt files. When descending from scan-root,
child entries named .git, _build, .mooncakes, or target are skipped; if
one of those directories is passed explicitly as scan-root, it is scanned.
Symbolic links encountered during recursive source or rule traversal are
skipped. Files that fail to parse are reported as warnings and skipped; other
files continue to be scanned.
Document
Embedded documentation is available through the docs subcommand:
moon runwasm moonbit-community/moongrep -- docs --list
