NORMAL MODE

Vim has 2 main "modes", that chance the behavior of all your keys. The default mode of Vim is Normal Mode and is mostly used for moving the cursor and navigating the current file.

Some important (or longer) commands begin with ":" and you will see the text you enter next at the bottom left of the screen.

:q[uit] - quit (the current window of) Vim. ("Window" here is internal to Vim, not if you have multiple OS-level windows of Vim open at once.)
:q! - force quit (if the current buffer has been changed since the last save)
:e[dit] {filename} - read file {filename} into a new buffer.

Gollum Guard

Gollumn requires changes to be commited before the server will pick them up for display.

This is a simple workflow that uses guard livereload to continually amend a sessions commit while you work with local files in your gollum wiki. You can use this with any guard task, really, but I like live reload to refresh my broswer.

For live reload to work, you need the extension installed in your browser

Introduction

If you are familiar with Java's generics, and are coming to Rust, you might be lead to assume that its generics are working the same way.

However, due to the different type systems, and different implementation details, there are quite a few differences between generic code in both languages.

This document tries to give a short summary about those differences:

4. Choose: Sublime Text 2 > Preferences > Key Bindings - User

5. Add:

   { "keys": ["super+ctrl+t"], "command": "timestamp" }

To make command+ctrl+t perform the insertion.
Make sure to add a comma after the previous keymap entry, if present.
