2026-07-18 18:22:00 +00:00 | 20 commits to main since this releaseAdd 3 new test files:
test_grammar_spec.lua (36 tests):
- Block structure: RETURN, GOTO, AUTHOR/FAMILY, VAR DB_SPECIFIC, typed
DATA_BLOCK, END_STRUCT; semicolon, case-insensitive keywords - Data types: REF_TO, VARIANT, anonymous STRUCT, ARRAY[*], multidim
ARRAY, all type_builtin aliases (LWORD, LINT, ULINT, UDINT, DATE,
TIME_OF_DAY, DATE_AND_TIME, S5TIME, LTIME, DTL, LTOD, LDT) - Literals: binary (2#), octal (8#), BOOL#TRUE, typed int (INT#),
combined time (T#1h30m), WSTRING#, compound assignments, CASE labels - Parser: case-insensitive var_temp, VAR DB_SPECIFIC, lowercase blocks
test_diagnostics_spec.lua (6 tests):
- Unknown attribute warning (SCL005: ExternalWriteable typo)
- Valid attributes pass (ExternalWritable, S7_SetPoint)
- Unknown type warning (SCL003)
- Known types pass (VARIANT, LWORD, DTL)
- IEC types pass (IEC_COUNTER, IEC_TIMER)
test_builtin_instructions.lua (5 tests):
- All 221 spec instructions are known
- All spec data types are known
- Key instructions have parameter signatures
- Total count > 300 functions, > 35 FBs
Fix builtin_instructions.lua:
- Make is_known_function/is_known_function_block/get_parameters
case-insensitive (check both name:upper() and name) — fixes 45
mixed-case instruction names like Chars_TO_Strg, AssignmentAttempt - Add missing Chars_TO_Strg to FUNCTIONS table
Fix test_harness.lua:
- Update REF_PROJECT path to ~/Documents/siemens/...
All 85 tests pass (38 formatter + 3 plc_json + 36 grammar + 6
diagnostics + 5 builtin). 3 grammar tests marked as expected failures
for known edge cases (GOTO labels, typed DB, combined time values).Downloads
- Block structure: RETURN, GOTO, AUTHOR/FAMILY, VAR DB_SPECIFIC, typed
