Custom hyperlinks question

[guillermoamaral]

Is there any way to use @uiw/codemirror-extensions-hyper-link but with any arbitrary text instead of an URL (customizing the click even handling) and without using markdown?

For instance, lets supose I have a code editor where I show user code, and the conde contains a global MyClass, and I want to let the user to "browse" this global by means of a link:

new MyClass();

so when users clicks on MyClass, they are guided to the definition of such global.

Thanks!

@guillermoamaral Upgrade v4.21.4

Custom match content

import { EditorView } from '@codemirror/view';
import { EditorState } from '@codemirror/state';
import { hyperLinkExtension, hyperLinkStyle } from '@uiw/codemirror-extensions-hyper-link';

const code = `Hyper Link\n====`;

export const hyperLink: Extension = [
  hyperLinkExtension({
    regexp: /Hyper/gi,
    match: { Hyper: 'https://google.com' },
    handle: (value) => {
      if (value === 'Hyper') return 'https://google.com';
      return value;
    },
  }),
  hyperLinkStyle,
];

const state = EditorState.create({
  doc: code,
  extensions: [hyperLink],
});

const view = new EditorView({
  parent: document.querySelector('#editor'),
  state,
});

Nice! However, would it be possible to:

• Specify a rage rather than a regex? I'd like to have the chance to enable links in a given list of globals. For example, in the following code, I'd have links in SomeClass, SomeType and MyFavoriteGlobal: a = new SomeClass(SomeType); b = a.blah(MyFavoriteGlobal)
• A more React-ish way to handle the link?. I'd like to specify a function to handle the click on the link rather than the default treatment (opening a page).
• To have underline style instead of the link icon at the end?. The icon is ok but needs more space and a underlined style is commonly interpreted as a link.

Thanks in advance!

@guillermoamaral Manipulating editor text, causing editing problems. A definition with a similar syntax may be required if you need to define URL text styles.

[guillermoamaral]

What about handling the click event? Isn't it possible to do something particular (instead of the default behavior)?

[jaywcjlove]

@guillermoamaral If I define an anchor option, I don't know if it can solve your problem.

hyperLinkExtension({
  regexp: /Hyper/gi,
  match: { Hyper: 'https://google.com' },
  handle: (value) => {
    if (value === 'Hyper') return 'https://google.com';
    return value;
  },
+  anchor: ($dom) => {
+    $dom.className = 'cm-hyper-link-icon';
+    return $dom
+  }
})

Would I be able to manage the click event in my app? I'm not sure if such option will allow me to do that.

Great! This really helped!

I'm struggling with the regex though as it matches things that I wouldn't like it to do.

I'm using /\b[A-Z].*?\b/g as regex. For instance, in the following example, the regex matches Answer in the comment but I know beforehand that that is not meant to be "linkable" (i.e., I can check easily that that, a) that is not a valid global, and b) it is inside a comment, so I would exclude it from the links if I had my way).

I will continue exploring alternatives anyway but if you could rather extend the specification of decorations (with something such as from and to positions), I would really appreciate it!.

Thanks!

@guillermoamaral You can list your desired api design

[guillermoamaral]

Ideally, it would be nice to able to specify the positions, start and to, of the hyperlinks texts, even when the to position was the one used to place the hyperlink icon as it is now (currently, both positions are determined internally by the MatchDecorator and passed as the arguments to the decorate callback). Probably this cannot be done as CodeMirror manages all this by its own.

Alternatively, it would be nice to have the chance to specify a callback to determine whether a piece matching the regex is actually a link. As I mentioned before, I know exactly what word can have a link as I have the list of globals.

Again, probalbly none of these can be done easily. In any case, thanks for your response.

@guillermoamaral

const hyperLink = [
  hyperLinkExtension({
    regexp: /codemirror/gi,
    match: { codemirror: 'https://google.com' },
-    handle: (value) => {
+    handle: (value, input, from, to) => {
      if (value === 'Hyper') return 'https://google.com';
      return value;
    },
  }),
  hyperLinkStyle,
];
