User Guide/The Script Controller

The Script Controller is a subdialog of the STx Workspace GUI, displayed in the upper right part of the window, and provides a convenient way to develop and run STx scripts.

To hide or show the STx Script Controller, use the Workspace menu item "Scripts > Show Scripts".

Note: The Find / Select dialog of the detail view is displayed in the same part of the GUI as the Script Controller. Only one of both dialogs can be visible.

Dialog Elements

ScriptFile

Press this button to open the standard open-file dialog to select a script file. The full path of the selected file is displayed as caption of the button.

New

Press this button to create a new script file via the standard new-file dialog. If a new file is created, it is also selected and opened in the external text editor.

Content of a new script file created via the new-button:

//{{4.2.14 (8805)}{2016.01.19  10.32.20} - automatically created version information - do not change or delete this line}

[Macro testfile args: #arg1 #arg2 #arg3 #arg4 #arg5 #rest]
//>> begin of script - enter your source code below this line

//<< end of script
// AutoCloseSF   := 0 // close all used sound files automatically on exit
// ShowLogOnExit := 0 // close bscript log-window automatically (no wait)
exit 1 int 0

Edit -

Open the selected script file in the text editor.

Test -

Use this button to test if the script file can be loaded (syntax check) and if it is compatible with your STx release. Note: If the script file can not be loaded, a short error message is displayed in a dialog box and detailed error messages are written to the STx log window.

Run -

The script file is loaded into the BScript runtime environment and the macro selected by the combobox Macro is executed. See the options Debug and Console for the selection of special run modes of a script.

Debug

Check this option to run the selected macro in the debug mode and uncheck it, to execute the macro in without debugging. If the dubug mode is enabled, the Break-mode of the debugger is entered before the execution of the macro begins.

Console

Check this option to run the script file in the console mode. If the Run button is pressed, the script file is loaded and the console is started. This mode can be useful, e.g. to test some macros during the development of a complex script package or to load a script file that implements a set of special commands to be used in the command line.

Running a script

To run an STx script from the mighty STx Script Controller, do the following:

1. Select a script file by clicking the "Script File" button. STx will provide you with a file selection dialog labelled "Select script file" allowing you to tell STx which script file to use.
2. Choose the macro to be run from the "Macro" combobox. In this comobox, STx lists all macros available in your script file.
3. If your macro expects arguments, provide them in the "Arguments" field.
4. To finally execute the macro, either press the button, or choose the menu item "Scripts > Run", or just press the Enter key while in the "Arguments" combobox.

You can also add scripts and store their arguments in the "Application & Setup Tree" under the entry Scripts.

Debugging a script

Just check the "Debug" checkbox. Now when you execute the script, the STx debugger will automatically open.

Command History

A history of arguments passed to the script is stored and can be retrieved by selecting an entry from the "Arguments" combobox.

The Console

If you press the Console button, the Console application is started. The Console is a command line interface to an STx shell.

The Console can:

1. process commands on a line by line basis
2. process multiple commands pasted from the clipboard
3. maintain a command history (up/down keys)

The Console cannot:

1. process IF or WHILE control statements

The Console implements the following additional commands:

exit

cls|clear

cd

pwd

ls

log

list

setcon

stx

sts

use

Other ways to select / run STx Scripts

• Script files can be added to the Script section of the The Application & Setup Tree of the Workspace. Scripts stored in the workspace can be started quickly and its also possible to edit or debug the scripts and to assign startup arguments. To add a script file, drop it on the workspace window (file extion: .sts) or use the context menu.
• You can also open the STx Console to run a script via the command line.
• If a script file filename.sts is dropped on the workspace, a dialog comes up to select a function for the script file:
  • Add the file to the [[User_Guide/Workspace/Application_and_Setup_Tree|The Application & Setup Tree]
  • Run the macro filename defined in the script file
  • Select the script file as the current file of the Script Controller
  • Edit the file filename.sts

The Console was added to STx in version 3.9. It is currently in its baby shoes, so please be nice to it, and report any misbehaviour.
