A simple tool that allows you to execute javascript in the command line as if you were in a browser. Built on-top of PhantomJS and acts as a well-behaved unix tool.

Wait, isn't this just NodeJS? No, they are for different things. BooJS gives you the full DOM, you can call document in BooJS and import arbitrary browser javascript libraries.

#Setup
gem install boojs

boojs [-e statement] [-t timeout] [-v file] [file]

The following options are available:

• -e - Pass a javascript statement to execute after the file (if a file is provided) and then immediately terminate unless -t is set.
• -t - Close the program after N seconds have passed, if an exception is raised before this, terminate immediately
• -v - Verify that a file contains no javascript syntax errors. Returns 0 if there are no errors.

Open a javascript pipe that reads from stdin, writes via console.log to stdout, prints exceptions via stderr, and exits with a return code of 1 if there are errors.

(sh)>boojs

Same as boojs but read the javascript file before reading from stdin. (i.e. preload a javascript file into your environment)

(sh)>boojs code.js

Execute a javascript statement, and then immediately exit. Exceptions will return 1.

(sh)>boojs -e "console.log(document);"

Execute a javascript statement, and then wait 4 seconds before exiting. Exceptions will return 1 and end execution early.

(sh)>boojs -e "console.log(document);" -t 4

Verify that a file contains no javascript runtime initialization errors

(sh)>boojs -v code.js
(sh)>echo $?
0
