I am trying to develop a feature in my VS Code extension that allows me to retrieve the range of a custom word when I hover over it, provided that the line of text matches a specific pattern. Here is the code snippet I have implemented so far:
vscode.languages.registerHoverProvider('.mylanguage', {
provideHover(document, position, token) {
// define `hoverRange` somewhere here
const hoverLineText = document.lineAt(position.line).text;
const pattern = new RegExp("\\w+\\s{0,}\\(.{0,}\\s{0,}\\)");
if(pattern.test(hoverLineText)){
hoverRange = document.getWordRangeAtPosition(position, pattern);
}
console.log(hoverRange);
//etc. ...
The expected behavior is that upon hovering on any part (even whitespace) of a string like myFunction ( ), the console should output the value of hoverRange, which should include the closing parenthesis ).
However, currently, nothing is displayed in the console when hovering over whitespace. To obtain the complete range of the string, I must specifically hover over myFunction.
How can I modify my VS Code extension to consider myFunction ( ) as a single unit?
