OpenEdge ABL Formatter

VSCode extension for Progress OpenEdge ABL code formatting.

This extension uses tree-sitter-abl implementation by Kamil Jakubus.

Current status

The OpenEdge ABL Formatter is now available in the VS Code Extension Marketplace.

Note:

We currently recommend not using the formatter with the on save trigger.

Use formatting cautiously, especially when working with existing code that is difficult to test.

Usage

Use default VSCode formatting commands:

Format Selection: Formats only the selected lines of code. CTRL+K CTRL+F

Also, you can enable or disable formatting on save:

"editor.formatOnSave": true

Alowed file extensions:

.p
.cls
.i
.w

Overriding Settings:

For development reasons, we implemented a mechanism to override formatting settings for a specific file. You can also use this feature by adding a leading comment in your code file:

Example:

/* formatterSettingsOverride */
/* { 
"AblFormatter.blockFormatting": true,
"AblFormatter.assignFormatting": true,
"abl.completion.upperCase": false
} */
def var a as integer no-undo init 1.

repeat while true:
    assign
    a = 10.
    message a.
end.

For more examples you can check out our test directory

Debugging

We implemented debug mode for looking into tree-sitter issues. You can also enable it:

First you have to format the document.
Then you can enable debug mode by pressing Abl Formater button in the middle bottom of the editor.
Hover on highlighted parts of code to get more information and see the tree view.
