  • 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:

FOREWORDS

I don't mean the snippet at the bottom of this gist to be a generic plug-n-play solution to your search needs. It is very likely to not work for you or even break things, and it certainly is not as extensively tested and genericised as your regular third-party plugin.

My goal, here and in most of my posts, is to show how Vim's features can be leveraged to build your own high-level, low-maintenance, workflows without systematically jumping on the plugins bandwagon or twisting Vim's arm.

Dealing with autocommands

Anatomy of a minimal autocommand

autocmd BufNewFile,BufRead *.foo set filetype=html
  • BufNewFile,BufRead is the list of events that trigger this autocommand.
  • *.foo is the pattern we want to match against the data returned by the event.
  • set filetype=html is the command we want to execute when the pattern matches the data returned by the event.

VimWiki Cheatsheet

[number] refers to the wiki number, set by the order in your vimrc. The default is 1.

Wiki Management

  • [number] <leader> ww - open wiki index file
  • [number] <leader> wt - open wiki index file in new tab
  • <leader> ws - list and select available wikis
  • wd - delete wiki page

Instructions for exporting/importing (backup/restore) GPG keys

Every so often I have to restore my gpg keys and I'm never sure how best to do it. So, I've spent some time playing around with the various ways to export/import (backup/restore) keys.

Method 1

Backup the public and secret keyrings and trust database

cp ~/.gnupg/pubring.gpg /path/to/backups/
cp ~/.gnupg/secring.gpg /path/to/backups/
cp ~/.gnupg/trustdb.gpg /path/to/backups/

or, instead of backing up trustdb...
