VSCode custom font ligatures, display two symbols as one?

Question

I would like to display list.emptyqm() as list.empty?() in function names for specific language. So, two symbols qm if they are at the end of the function name should be displayed as ? (possibly some unicode symbol looking similar to question mark).

Is that possible in VSCode?

The VSCode already knows that piece of text is string, or function-name/keyword/variable-name (as it highlights it properly), so the ligature should be displayed only if qm are the last characters of function-name/keyword/variable-name. It shouldn't be displayed in the middle of the function name, like aqma() shouldn't be displayed as a?a() .

Answer 1

You seem to misunderstand what a ligature is. A ligature describes how two individual letters can be combined to form a visual pleasing appearance. A ligature never changes the syntax of a text. Hence, converting qm to ? is a completely different thing.

Replacing text in vscode is of course possible, for instance as part of the format command. You can register your own formatter and determine the text edit actions that you want to be applied, including the transformation of these character sequences.
