Find parse problems

Recipe IDio.moderne.mainframe.ingestion.FindParseProblems
Artifactio.moderne.recipe:recipes-mainframe

Report every source the parsers could not read, could not read as what it was taken for, or read with a member missing, and mark each where it prints. A file that did not parse is a FAILURE when the parser should have read it, and MISCLASSIFIED when it is not what its name says — a control card kept as .cbl, a member with no card beginning // — which the parser reports under an exception of its own. A program whose COPY found no member, and a job whose step, INCLUDE or input DD names a procedure or member that was not supplied, is UNRESOLVED: it parsed, and every analysis reads it as though the member were empty. A member no parser claimed is read as text, and is reported when it has no extension or looks like code. Every COPY also gets its CopybookSource row, and every failure a Findings row.

Usage​

Run this recipe

This recipe has no required configuration options. Users of Moderne can run it via the Moderne CLI.

You will need to have configured the Moderne CLI on your machine before you can run the following command.

shell
mod run . --recipe FindParseProblems

If the recipe is not available locally, then you can install it using:

RELEASE resolves to the newest release and LATEST to the newest build of any kind, including snapshots. Either one lets mod config recipes upgrade pull in later versions without editing this command; a pinned version stays where you put it.

mod config recipes jar install io.moderne.recipe:recipes-mainframe:RELEASE

Data tables​

Parse quality
io.moderne.mainframe.analysis.table.ParseQuality

Every source the parsers could not read, could not read as what it was taken for, or read with a member missing, with a verdict on what to do about it.

Export after a run
mod study . --last-recipe-run \
--data-table io.moderne.mainframe.analysis.table.ParseQuality
ColumnDescription
Source pathThe file.
LanguageWhat the file was read as: COBOL, COPYBOOK, JCL, BMS, or TEXT for a file no parser claimed.
ProblemPARSE_FAILURE or TIMEOUT for a file the parser gave up on; WRONG_LANGUAGE for a file the parser refused because it is not its language; TEXT_FILE for a member no parser claimed that has no extension or looks like code; MISSING_COPYBOOK, MISSING_PROC, MISSING_INCLUDE and MISSING_SYSIN for a member the source names that was not supplied.
VerdictFAILURE when the parser should have read the file and did not; MISCLASSIFIED when the file is not what it was taken for, so no parser could have; UNRESOLVED when the file parsed but names a member that was not supplied.
MembersThe members not found, comma separated, or empty.
ReferencesHow many statements name a member that was not found; 0 for a file that did not parse.
DetailThe parser's reason, what a text file looks like, the steps that name a missing procedure, or the data sets a missing member was named in.
Copybook source information
org.openrewrite.mainframe.cobol.table.CopybookSource

Information about copybook references in a COBOL source.

Export after a run
mod study . --last-recipe-run \
--data-table org.openrewrite.mainframe.cobol.table.CopybookSource
ColumnDescription
Source pathThe source path of the file that contains the copy statement.
Copybook nameThe copybook name from a copy statement in a COBOL source.
Copybook source pathThe source path of the copybook that was resolved during resolution of copybooks.
Resolution statusThe status of the resolved copybook in a copy statement.
Marked wordThe current word being visited from the post-processed LST.
Findings
io.moderne.mainframe.analysis.table.Findings

Everything the mainframe analyses found wrong, ranked, with the evidence for each and the line it is on. Sort on priority.

Export after a run
mod study . --last-recipe-run \
--data-table io.moderne.mainframe.analysis.table.Findings
ColumnDescription
Priority1 for CRITICAL down to 4 for LOW, so the table sorts.
SeverityCRITICAL for code that cannot do what it was written to do, HIGH for what will break a migration if not decided deliberately, MEDIUM for what is worth knowing first, LOW for cleanup.
CategoryWhat kind of problem it is, which is what groups the report into sections: DEAD_RULE, UNREACHABLE_CODE, COPYBOOK_DRIFT, MIGRATION_BLOCKER, RANGE_PATHOLOGY, DEAD_DATA, COMPLEXITY, LAYOUT_DRIFT, IMS_PCB_MISMATCH, IMS_SEGMENT_NOT_SENSITIVE, IMS_IO_AREA_MISMATCH, MFS_MESSAGE_LENGTH, SCREEN_ITEM_UNREACHED, SCREEN_FIELD_UNREACHED, PARSE_FAILURE, UNDOCUMENTED, STALE_DOCUMENTATION, STALE_REFERENCE, UNENFORCED_BUILD_ORDER, UNSCHEDULED_JOB, AUTOCALL_RESOLVED_REFERENCE, UNRESOLVED_EXECUTION_PATH, INHERITED_SETTING, UNLOAD_NEEDS_REDESIGN, UNLOAD_ACCESS_MODE, UNLOAD_CONSISTENCY, UNLOAD_OUTPUT_WIRING, MIXED_SUBSTITUTION.
ProgramThe COBOL program, or the copybook where the finding is about one.
SummaryThe finding in one sentence, written to be read on its own.
EvidenceWhy this is claimed — the conditions that conflict, the two declarations that differ, the caller that made the paragraph unreachable. A finding nobody can check is a finding nobody will act on.
WhereThe paragraph, section or data item the finding is in.
Source pathThe file, so the finding can be opened.
Source files that had results
org.openrewrite.table.SourcesFileResults

Source files that were modified by the recipe run.

mod study . --last-recipe-run \
--data-table org.openrewrite.table.SourcesFileResults
ColumnDescription

Source path after the runA recipe may modify the source path. This is the path after the run. null when a source file was deleted during the run.
Parent of the recipe that made changesIn a hierarchical recipe, the parent of the recipe that made a change. Empty if this is the root of a hierarchy or if the recipe is not hierarchical at all.
Recipe that made changesThe specific recipe that made a change.
Estimated time savingAn estimated effort that a developer to fix manually instead of using this recipe, in unit of seconds.
CycleThe recipe cycle in which the change was made.
Source files that had search results
org.openrewrite.table.SearchResults
