Customization Tips

Professor Simpkins keeps his dotfiles on GitHub

bash

These go in your ~/.bash_profile.

    # My prompt string, which you see when I demonstrate in the terminal
    export PS1="\[\033[32;1m\][\u@\h \w]\n$ \[\033[0m\]"

    # Aliases to save some typing
    alias ll='ls -la'

    # A personal bin directory
    export PATH=~/bin:$PATH

Checkstyle Script

Download checkstyle-6.2.2.jar to your ~/bin directory. Create a file named checkstyle in your ~/bin directory with the following contents:

    #!/usr/bin/env bash

    java -jar ~/bin/checkstyle-6.2.2.jar "$@"

Then make it executable:

    $ cd bin
    $ chmod +x checkstyle

Now you can run checkstyle on any Java file like this:

    $ checkstyle Foo.java
    Audit done. Errors (potential points off):

Atom

First, be sure to familiarize yourself with basic Atom usage. The Getting Started guide is enough to make you quite proficient. In Atom Preferences, make sure the following are checked:

• Show Indent Guide draws a vertical line at your preferred line length column in editors. Preferred line length should be set to 80.
• Show Invisibles draws greyed-out characters for spaces, TABs, hard returns.
• Show Line Numbers displays line numbers in the left gutter in editors. Personal preference, but I find it useful.
• Soft Tabs causes the editor to insert spaces instead of TAB characters when you hit the TAB key.
• Soft Wrap wraps lines visually on word boundaries. Together with Show Line Numbers you get readable text and can still easily tell long single lines.
• Soft Wrap at Preferred Line Length wraps lines visually on word boundaries at your preferred line length.

Sublime Text

To make Sublime Text always use spaces instead of tabs, add the following lines to your user settings under preferences:

    {
        "tab_size": 4,
        "translate_tabs_to_spaces": true,
        "rulers": [80],
        "trim_trailing_white_space_on_save": true
    }
