Allow custom inline style matcher

[dino115]

Hi,
first of all, thank you very much for your great work!

For my project i have to change the inline style handlers, because up to now we have used a slightly different markdown syntax. I.e. ** for bold, * for italic, and _ for underline and i have to add some additional inline styles.

So i quickly added a configuration for custom inline style matchers. You can use it in the following way:

const markdownPlugin = createMarkdownPlugin({
  customInlineMatchers: {
    BOLD: [/\*\*(.+)\*\*\s$/g, /__(.+)__\s$/g],
    ITALIC: [/\*(.+)\*\s$/g],
    UNDERLINE: [/_(.+)_\s$/g],
    CODE: [/`([^`]+)`\s$/g],
    STRIKETHROUGH: [/~~([^~]+)~~\s$/g],
    MARK: [/==(.+)==\s$/g],
  },
  features: {
    inline: [
      'BOLD',
      'ITALIC',
      'UNDERLINE',
      'CODE',
      'STRIKETHROUGH',
      'MARK',
    ],
  },
});

What do you think about this?

Update: I've added the ability to wait for a whitespace character after the markdown applies a style to the text. To use this, you have to group the ending whitespace in the regular expression.

This is neccessary if you will use the same char in different styles. I.e. ** for bold and * for italic.

BOLD: [/\*\*(.+)\*\*(\s)$/g],
ITALIC: [/\*(.+)\*(\s)$/g],

Sorry for the slow response here—I see where you're going with this and why it'd be use, but I'm not sure I'm ready to maintain all this code we don't use 😕 I'm afraid it'll grow stale and buggy, and it won't be a good experience.
