Writing a TextMate Grammar: Some Lessons Learned

February 17, 2014 at 14:35:46

Although TextMate has been around for a long time (in computer years) and many language bundles exist, it is startling to find that the process of writing a language grammar remains poorly documented. Having recently managed to write a grammar of my own for the first time, here are some things I learned along the way.

Time Involved

Writing a grammar can be a slow business. It took me some weeks just to prepare, collecting information and locating and studying the existing instructions and documentation.

Nginx Basics for Ubuntu

Please see http://wiki.nginx.org/Main for more information. See http://arstechnica.com/gadgets/2012/11/how-to-set-up-a-safe-and-secure-web-server/ for a tutorial on how to install Nginx.

Installation

To install, you can install the version which is in the standard Ubuntu repositories but it is normally quite old and will not have the latest security patches. The best way is to update the repositories first:

apt-get update
apt-get install python-software-properties

apt-get upgrade

$spotlight_files = (dir $spotlight_folder)

foreach ($file in $spotlight_files) {
    $saved_name = (Split-Path $file -Leaf) + ".jpg"

Postgres Cheatsheet

This is a collection of the most common commands I run while administering Postgres databases. The variables shown between the open and closed tags, "<" and ">", should be replaced with a name you choose. Postgres has multiple shortcut functions, starting with a forward slash, "". Any SQL command that is not a shortcut, must end with a semicolon, ";". You can use the keyboard UP and DOWN keys to scroll the history of previous commands you've run.
