COBOL (first) - Allow parts of code to be ignored by Language Server

[FALLAI-Denis]

Hi,

Extract from:

• COBOL (first) - Allow use of "exotic" EXEC / END-EXEC block in source programs #439

Description of the enhancement requested

We would like some parts of the (COBOL) source code not to be analyzed by the (COBOL) Language Server, this in order not to trigger errors or warnings on certain parts of the code, (which disable ZOE features, or pollutes the problems output):

• intentionally unreachable code, ("watchdog" to ensure that we do not inadvertently exit in sequence from a performed block)
• "exotic" code processed by a preprocessor before compilation, (see issue COBOL (first) - Allow use of "exotic" EXEC / END-EXEC block in source programs #439)
• syntax not supported or poorly recognized by the Language Server, (in particular when using conditional compilation that cannot be resolved outside of a real compilation process, such as using a DEFINE compilation option)

For this we propose that the (COBOL) Language Server recognizes specific comments which would frame the code which should not be analyzed:

• *>BEGIN-LS-IGNORE
• *>END-LS-IGNORE

Thanks.
