Netrw Cheatsheet (Vim's File Browser)

See also:

  • vinegar.vim, which makes - open netrw in the directory of the current file, with the cursor on the current file (and pressing - again goes up a directory). Vinegar also hides a bunch of junk that's normally at the top of netrw windows, changes the default order of files, and hides files that match wildignore.

    With vinegar, . in netrw opens Vim's command line with the path to the file under the cursor at the end of the command. ! does the same but also prepends ! at the start of the command. y. copies the absolute path of the file under the cursor. ~ goes to your home dir. Ctrl+6 goes back to the file (buffer) that you had open before you opened netrw.

To launch netrw:

vimgrep

  • Vimcasts on vimgrep

  • Uses native vim regexes (which are slightly different from the regexes used by grep, ack, ag, etc) so the patterns are the same as with vim's within-file search patterns.

You can do a normal within-file search first, then re-use the same pattern to

Unicode in Python 2 and 3

My notes on unicode handling in Python 2 and 3, with runnable tests.

So far this is very heavily based on Ned Batchelder's Pragmatic Unicode, it's basically my notes on that presentation, with the examples from that presentation in the form of runnable tests. I may add more to these notes in time though.

HTML Tags You Can Use on GitHub

Wherever HTML is rendered on GitHub (gists, README files in repos, comments on issues and pull requests, ...) you can use any of the HTML elements that GitHub Flavored Markdown (GFM) provides syntactic sugar for. You can either use the syntactic sugar that GFM (or other GitHub-supported markup language you're using) provides or, since Markdown can contain raw HTML, you can enter the HTML tags manually.

But GitHub also allows you to use a few HTML elements beyond what Markdown provides by entering the tags manually, and some of them are styled with CSS. Most raw HTML tags get stripped before rendering the HTML. Those tags that can be generated by GFM syntactic sugar, plus a few more, are whitelisted. These aren't documented anywhere that I can find. Here's what I've discovered so far:
