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

About Awk

Awk is a text processing language that comes standard with most distributions of Linux/Unix. In my personal experience, awk is faster at parsing, filtering, and writing text files than either python or R with few exceptions. This cheat sheet goes over the basic awk commands that I use the most.

How does awk work

Awk processes a text file line by line and is used to apply some condition to each based on its contents. I have found the most use for it on text files of large matrices (that is text files with distinct, consistent columns) or on text that has clear consistent delimeters. Awk interpretes each column in your line and stores it as a variable from 1 to n where n is the number of columns you have. Say you have a file that looks as such:

ID  gene_name type  start stop Chr
ENSG0 C1orf22 protein_coding 178965 183312 chr2

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.

Guide to your first Tree-sitter grammar

NOTE: The Tree-sitter API and documentation has changed and improved since this guide was created. I can't guarantee this is up to date.

About

Tree-sitter is the new way Atom is providing language recognition features, such as syntax highlighting, code folding, autocomplete, and more. In contrast to TextMate grammars, which work by regex matching, Tree-sitter will generate an entire syntax tree. But more on that can be found in it's own docs.

Here, we look at making one from scratch.

Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

There are always 24 hours in a day.
February is always 28 days long.
Any 24-hour period will always begin and end in the same day (or week, or month).

tmux 101 - the terminal multiplexer

Why tmux?

Why use a terminal multiplexer?
- Keeps your hands on the keyboard
- Keep multiple terminals in eyeshot
- Detach/re-attach remote session (eg. for long-running processes)
Like screen, but better
