Source folding in HLASM

[SG-A47]

Development environment used

• Z Open Editor version:
• Editor Platform
  • [x] Visual Studio Code
• Editor Platform Version:
• Operating System Windows 10 2004

Problem Description

Source folding in HLASM doesn't work usefull when you have commented code. The arrow is presented at a code line which is commented. With a click on the arrow active code will hide. In HLASM this is not usefull.

Expected behavior

• Source folding should be possible to fold a bunch of comment lines
• There should be the possibility to activate folding of all comments or special comments. When commented code starts with one star and a real text comment starts with two stars, ther sould be the possibility to distingiush between them.

Can't add a picture with an example.

Thanks @SG-A47. Great idea.

Hi @SG-A47,

I suggest you look at COBOL folding rules #141.

I think you can apply same solution to HLASM source code.

Hi, COBOL folding let to the right extension. It is called "Explicit Folding". I realized source folding for assembler with these lines in the settings.json: <<< "editor.foldingStrategy": "auto", "editor.defaultFoldingRangeProvider": "zokugun.explicit-folding",
"workbench.colorTheme": "Blackboard", "editor.showFoldingControls": "always", "notebook.showFoldingControls": "always", "editor.folding": true, "explicitFolding.debug": false, "explicitFolding.wildcardExclusions": ["cobol"],
"explicitFolding.rules": { "hlasm":{ "beginRegex": "((^[]{1} )|(^[]{1}$)|(^[]{1}[A-Z]))", "whileRegex": "((^[]{1} )|(^[]{1}$)|(^[]{1}[A-Z]))", "foldlastline": "false", "nested": "true", "autoFold": "true" } }

<<< I made the following assumptions:

• A comment line which should be folded starts with a single star and is followed by an space or a letter/number. Empty lines are part of the folded region too. In that case you can´t use \n for the end of line. You have to use the $ sign.
• I use comment lines starting with two stars as real text comments. So they are not folded.
• I use Autofold, but I´m not sure that I will use it as a default.

Thanks to FALLAI-Denis for the hint.
