Software Setup

To participate in a Library Carpentry workshop, you will need access to the software described below. In addition, you will need an up-to-date web browser.

We maintain a list of common issues that occur during installation as a reference for instructors that may be useful on the Configuration Problems and Solutions wiki page.

A spreadsheet program

For this workshop you will need a spreadsheet program. Many people already have Microsoft Excel installed, and if you do, you're set! If you need a spreadsheet program, there are a few other options, like OpenOffice and LibreOffice. Install instructions for LibreOffice, which is free and open source, are here.

Windows

  1. Download the LibreOffice installer.
  2. Double click to install
  3. Double click on icon to open.

Mac OS X

  1. Download the LibreOffice installer.
  2. Double click to install
  3. Double click on icon to open.

Linux

  1. Download the LibreOffice installer.
  2. Double click to install
  3. Double click on icon to open.

The Bash Shell

Bash is a commonly-used shell that gives you the power to do simple tasks more quickly.

Windows

Video Tutorial
  1. Download the Git for Windows installer.
  2. Run the installer and follow the steps bellow:
    1. Click on "Next".
    2. Click on "Next".
    3. Keep "Use Git from the Windows Command Prompt" selected and click on "Next". If you forgot to do this programs that you need for the workshop will not work properly. If this happens rerun the installer and select the appropriate option.
    4. Click on "Next".
    5. Keep "Checkout Windows-style, commit Unix-style line endings" selected and click on "Next".
    6. Keep "Use Windows' default console window" selected and click on "Next".
    7. Click on "Install".
    8. Click on "Finish".
  3. If your "HOME" environment variable is not set (or you don't know what this is):
    1. Open command prompt (Open Start Menu then type cmd and press [Enter])
    2. Type the following line into the command prompt window exactly as shown:

      setx HOME "%USERPROFILE%"

    3. Press [Enter], you should see SUCCESS: Specified value was saved.
    4. Quit command prompt by typing exit then pressing [Enter]

This will provide you with both Git and Bash in the Git Bash program.

macOS

The default shell in all versions of macOS is Bash, so no need to install anything. You access Bash from the Terminal (found in /Applications/Utilities). See the Git installation video tutorial for an example on how to open the Terminal. You may want to keep Terminal in your dock for this workshop.

Linux

The default shell is usually Bash, but if your machine is set up differently you can run it by opening a terminal and typing bash. There is no need to install anything.

OpenRefine

OpenRefine (previously Google Refine) is a tool for data cleaning that runs through a web browser, and any browser - Safari, Firefox, Chrome, Explorer - should work fine. You will need to download OpenRefine and install it, and when you open it, it will run through the browser, but you don't need an internet connection, and the data will all be stored on your computer.

Windows

  1. Download OpenRefine Windows kit installer.
  2. To use it, unzip, and double-click on openrefine.exe (if you're having issues with openrefine.exe try refine.bat instead)
  3. OpenRefine will then open in your web browser.
  4. If it doesn't open automatically, open a web broswer after you've started the program and go to the URL http://localhost:3333 and you should see OpenRefine.

Mac OS X

  1. Download OpenRefine Mac kit installer.
  2. Open the downloaded .dmg file
  3. Drag the icon in to the Applications folder
  4. Double click on the icon and Google Refine will then open in your web browser.
  5. If it doesn't open automatically, open a web broswer after you've started the program and go to the URL http://localhost:3333 and you should see OpenRefine.

Linux

  1. Download OpenRefine Linux kit installer.
  2. To use it, extract, and type ./refine
  3. OpenRefine will then open in your web browser.
  4. If it doesn't open automatically, open a web broswer after you've started the program and go to the URL http://localhost:3333 and you should see OpenRefine.

Text Editor

When you're writing code, it's nice to have a text editor that is optimized for writing code, with features like automatic color-coding of key words. The default text editor on macOS and Linux is usually set to Vim, which is not famous for being intuitive. If you accidentally find yourself stuck in it, try typing the escape key, followed by :q! (colon, lower-case 'q', exclamation mark), then hitting Return to return to the shell.

Windows

Video Tutorial

nano is a basic editor and the default that instructors use in the workshop. To install it, download the Library Carpentry Windows installer and double click on the file to run it. This installer requires an active internet connection.

Others editors that you can use are Notepad++ or Sublime Text. Be aware that you must add its installation directory to your system path. Please ask your instructor to help you do this.

macOS

nano is a basic editor and the default that instructors use in the workshop. See the Git installation video tutorial for an example on how to open nano. It should be pre-installed.

Others editors that you can use are Text Wrangler or Sublime Text.

Linux

nano is a basic editor and the default that instructors use in the workshop. It should be pre-installed.

Others editors that you can use are Gedit, Kate or Sublime Text.

SQLite

SQL is a specialized programming language used with databases. We use a simple database manager called SQLite in our lessons.

Windows

The Library Carpentry Windows Installer installs SQLite for Windows. If you used the installer to configure nano, you don't need to run it again.

macOS

SQLite comes pre-installed on macOS.

Linux

SQLite comes pre-installed on Linux.

If you installed Anaconda, it also has a copy of SQLite without support to readline. Instructors will provide a workaround for it if needed.
