Hints, Tips, Tricks, and Shortcuts[edit]

Command Line Tips[edit]

Helpful Hint

Slow typist? You can use the alias command. For example, to type the shortcut mt rather than merlin test you can add an alias: alias mt='merlin test'

If you'd like to make your aliases permanent (rather than lasting only for the current session) you can add them to your ~/.bash_aliases file.

Swift Tips[edit]

	Helpful Hint
	Print an empty line (i.e., just a new line) with: `print()` Print text without the default terminator with: `print(terminator:"Hello")` Create a string repeating a character n times with: `String(repeating:"!", count: 3)`

Emacs Tips[edit]

	Helpful Hint
	Web-mode supports both PHP and HTML in the same buffer. Web-mode can be activated with: `ALT`-`x` web-mode `RETURN`

Git Tips[edit]

Helpful Hint

Tags can be easily moved by using the --force option.

git tag --force J1154.Final
git push origin --force J1154.Final

Newly Installed and Updated Services[edit]

Disk Space Increased[edit]

The available disk space has been increased to 1.0 GiB.

Emacs Updates 27.1[edit]

Native support for JSON parsing
Built-in support for tab bar and tab-line

In order to ensure you receive the latest features, re-initialize your skeleton:

jane-williams@codermerlin:~/www$ skel-init

Then completely log off before logging back on. Run emacs (without any parameters) and wait for the initialization to complete.

Vapor Available[edit]

Swift Vapor applications are now available. See Vapor for configuration information.
