Workcraft supports scripting using JavaScript language. Two modes of script execution are supported:

• Interactively, by entering the script commands in the Javascript tab and pressing Ctrl+Enter to execute them. The output of the commands is redirected to the Output tab.
• In batch mode, by passing the script file name or a one-liner script after the -exec: command line parameter.

For batch mode it is often convenient to start Workcraft without GUI and without reading/writing configuration files. This is achieved by using -nogui and -noconfig command line parameter as follows (We presume that Workcraft home is in the search PATH and the platform-specific .sh/.bat extension of Workcraft runner is omitted):

workcraft -nogui -noconfig -exec:'/path/to/script.js'

If a script contains file operation commands, such as loading work files or exporting the models, then all the file names in these commands are relative to the working directory. By default this coincides with Workcraft home, however, an alternative working directory can be passed after the -dir: command line parameter, as follows:

workcraft -nogui -noconfig -exec:script.js -dir:'/working/directory/path/'

since v3.2.3 For a short JavaScript snippet, it may be more convenient to pass it directly in the command line:

workcraft -nogui -exec:'print("Hello!");exit();'

For more information about these and other Workcraft startup options see Command line interface document.

Here is a list of predefined wrapper functions, partitioned into categories, and global variables available for scripting.

• help(substring) – output all the helper functions whose name contains the given substring
• apropos(substring) – output all the helper functions whose name or description contains the given substring
• getHelp(substring, searchDescription) – return a string with all helper functions whose name contains the substring; if the searchDescription is true, then also search the function descriptions

• print(msg) – output msg to stdout and add a newline
• eprint(msg) – output msg to stderr and add a newline
• write(text, fileName) – write text to a file fileName (relative to the working directory) or to stdout if fileName is skipped

Note that conventional Java print functions can be also used, e.g. if you need to output text without adding a newline:

• System.out.print(text) – output text to stdout
• System.err.print(text) – output text to stderr

• startGUI() – start GUI
• stopGUI() – stop GUI and switch to console mode
• quit() or exit() – request Workcraft shutdown after script execution is complete

  Note that quit() and exit() do not terminate Workcraft immediately, and therefore should not be used in the middle of JavaScript program as a way to abort its execution. Instead throw('message') JavaScript statement should be used for this purpose.
