* First commit of order tool * More flexible match on module name. Bugfix on blank_or_comment * Report inexact offset comments in verbose mode. Bugfix for exact regex * Refactor checkorder into reusable isledecomp module * Find bad comments in one pass, add awareness of TEMPLATE * Refactor of state machine to prepare for reccmp integration * Use isledecomp lib in reccmp * Build isledecomp in GH actions, fix mypy complaint * Ensure unit test cpp files will be ignored by reccmp * Allow multiple offset markers, pep8 cleanup * Remove unused variable * Code style, remove unneeded module and TODO * Final renaming and type hints * Fix checkorder issues, add GH action and enforce (#2) * Fix checkorder issues * Add GH action * Test error case * Works * Fixes --------- Co-authored-by: Christian Semmler <mail@csemmler.com>
