runtimechecker: reject bad options; accept -h and --help - #888
Merged
Merged
Conversation
Add DaikonGetopt, a Getopt subclass that throws a UserError describing an unrecognized, ambiguous, or malformed option and handles -h and --help. Use it in Daikon and in the other tools that use Getopt. Remove Diff's -u and -z options, which had no effect. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The instrumenter and WriteViolationFile use DaikonGetopt. The instrument command reports a bad option and its usage message rather than ignoring the option. A missing .doc file is reported as a bug. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Review comments at @java/daikon/tools/runtimechecker/Main.java:
- Around line 94-95: Update the RuntimeException handling in Main so
Daikon.BugInDaikon is routed to Daikon.handleDaikonTerminationException before
the generic command-failure handling; preserve bug reporting for missing
InstrumentHandler.doc resources, including the instrument --help path.

….handle void; rename Main.fullUsageMessage; don't copy argv WriteViolationFile.main now delegates to mainHelper, like other Daikon programs.

The runtimechecker instrumenter and
WriteViolationFileuseDaikonGetopt. Theinstrumentcommand reports a bad option and its usage message rather than ignoring the option. A missing.docusage file is reported as a bug rather than silently skipped.DaikonGetoptgainsargsAfterLeadingOptions(which #886 also adds), a constructor that computes the usage message only if it is needed, andsetUsageHint.InstrumentHandlerusessetUsageHint(null), because its caller prints the usage message when the command fails.🤖 Generated with Claude Code
