PAWS runs on Windows, Mac, and Linux operating systems.

Windows

Download the installer and run it as administrator (right-click on the file you just downloaded and choose “Run as Administrator”). After successful installation, you will be asked if you want the PAWS program to start.

Mac OS X

  1. Download the installer.
  2. Double-click the installer file.
  3. Drag the PAWS icon to the Applications folder. PAWS will now be in your Applications folder.

Linux

Follow these steps:

  1. Download the installer.
  2. Using a Terminal widow, navigate to where you downloaded the installer.
  3. If you have previously installed PAWS, remove the old version by typing
    sudo dpkg -r paws
    and press ENTER.
  4. Now invoke the installer by typing
    sudo dpkg -i name_of_the_downloaded_deb_file
    and press ENTER.

When first running PAWS

You will be shown a dialog indicating that PAWS has not been run on your computer before.

  1. Click on the Create New Language button.
  2. You will be asked to save the newly created PAWS answer file in a directory.  We suggest putting it in your Documents directory under a (new) folder called “My PAWS”.  Type the name of the answer file you want to use in the “File  name” box and press the Save button.
  3. This brings up the Language Properties page.  Fill in each field for your language.  When you are done, click on the Next button.
  4. This brings up the Answer and Result File Information page.  Check the kinds of output results you want (what shows depends on which items are checked).  Change the location of any output files if needed.  Click on the Next button.
  5. This takes you to the main Contents page.  You are set to go now.

The next time you start PAWS from the desktop icon, it will take you to the page you were last on (normally the Contents page).

If you are using PAWS to produce a grammar write-up, you may want to work your way through the first two or three sections and then take a look at the writer output. This should help you to see “the big picture” of how PAWS works. To produce the writer output, click on the Generate Files icon.
