Check if table index is of integer type

2

`IF NOT line_exists( input-values[ value ] ).` but if value is of type `string`, this will dump and what you likely meant was `IF NOT line_exists( input-values[ table_line = value...

There is a very confusing blog about this https://blogs.sap.com/2021/10/19/new-kinds-of-abap-expressions/ ```abap REPORT zfh_test_syntax. CLASS lcl_test DEFINITION. PUBLIC SECTION. METHODS get IMPORTING ref TYPE REF TO data RETURNING VALUE(result) TYPE string. ENDCLASS....

For technical reasons, the statement "PROTECTED SECTION" or "PRIVATE SECTION" must exist in non-final global classes

Abaplint does not catch this yet (I don't know the consequences of not respecting this warning)

New check - no implicit rounding

1

Whenever converting from a decimal number type or a string type to a whole number type, implicit rounding can occur. ```abap DATA(float_in_string) = `9.54`. DATA: int type i. int =...

New check - no alphabetical comparisons

1

Report error when the operators `` are used on strings, as this does an alphabetical, not a numerical comparison which can lead to problems (e.g. `"11" < "9" == true`...

abaplint does not catch syntax error (char->string assignment)

1

Here, iv_transport has the domain trkorr (char20), it is a syntax error to pass it to a string parameter https://github.com/abapGit/abapGit/pull/5022/commits/483dcff5c5800d2ebd334c33b52c1d3638bbc737 I feel like abap sometimes allows it and sometimes doesn't....

add posix regex to obsolete_statement

2

(since 756) 

New rule: constant classes

6

if you have a domain with fixed values, specify a class which serves as constants of those values config ```json "constant_classes": { "mapping": [ {"blah": "cl_blah_constants"}, ... ] } ```...

Caching regexes

3

Could potentially lead to performance improvements if the regex objects are cached, and the regexes will become better organized: https://github.com/abaplint/abaplint/blob/f5e326823eee124c5dddbf80b535e50d53086df7/packages/core/src/abap/2_statements/combi.ts#L935-L937

line_only_punc quickfix can cause syntax errors

1

If you apply the fix here, abaplint will put the punctuation on the end of the commented line which causes a syntax error
