Preview any link or tweet directly within emacs

I found myself compiling a list of tweets and other links in org mode and was wishing I could easily pull in the tweet details to see them directly in the file. Notion does this nicely, and I couldn’t find anything existing that would give me that. Here’s a quick function to pull that data in automatically. If anyone else would find this useful, I can put a little more effort into polishing it.

I see that you use Spacemacs and the naming of the function is influenced by its naming convention. (using / to separate namespace) but note that by convention all symbols should prefixed with the file name/feature name. so instead of lp/expand-link-at-cursor, it should be link-preview/expand-link-at-cursor. also link-preview-api should first be declared. Since it seems to be a constant, you should use defcustom. third, by convention you should also use (provide 'link-preview) to declare the feature. Spacemacs by default turns off flycheck for elisp, by you should enable it and it will give you many useful suggestions.

Thanks for the input! Wasn’t aware of those parts of the convention, good to know.

I just updated my comment.

You're missing a Package-Requires in the package header. You should declare, at least, the "request" dependency and a minimum supported Emacs version. You'll want to enable lexical binding in your package's file. You have a number of linter errors you can see by using flymake and/or checkdoc.

Thanks! Will go in and fix these. I don’t write much elisp :)

just checked your latest code. - you can exit early if `PEEKALINK_API_KEY` is not found. - the indentation from L23 and forward are incorrect.
