Command Line Interface

command line interface

Command line input (left side)

Commands can be directly entered here.

In the Linux version of LS-PrePost, help comments are displayed here when the mouse cursor is placed over controls and other areas of the user interface.

In the Windows version, help comments are displayed below the Command Line Interface in the Status Bar

Last Command Field (right side)

The last command issued is displayed here.

When the user right-clicks in this area it expands upwards to display a list of previously issued commands. Right-clicking a second time shrinks the menu down to its original size.

Also, if a command is issued with missing criteria, an error message may be displayed here.

Almost all graphical user interface (GUI) interaction generates commands, and these commands are written to a file called lspost.cfile. Upon exiting LS-PrePost, this file can be renamed to replay the previous session using one of the following methods:

  • 1. LS-PrePost c=commandfile
  • This method launches the LS-PrePost GUI and executes the commands from the command file.

  • 2. LS-PrePost c=commandfile -nographics
  • This method does not launch the LS-PrePost GUI but still executes the commands in batch mode.

  • 3. File -> Open -> Command File
  • This method will open a command file selection dialog. Upon opening a command file, LS-PrePost will display the CFile Dialog.

Command Files can be a powerful tool and have many potential uses such as performing repetitive tasks and presenting a pre-recorded set of actions to an audience. The following commands can be inserted into a command file to provide additional control when composing a presentation:

  • interactive - switch the control from command file to interactive
  • resume/r/esc - any of these 3 will switch control back to command file
  • skip - skip commands that follow until an "endskip" is met
  • endskip - resume command execution
  • cfile pausetime 0.1 - set pausetime to 0.1 seconds

Below is a list of commands that can be entered on the Command Line in LS-PrePost. The list is only a subset of some of the more basic commands. For additional commands, please refer to the contents of lspost.cfile saved at the end of each LS-PrePost session. To see commands generated while interacting with the graphical user interface, watch the message window output.

Note: By default, orientation commands (such as those generated when the model is rotated) are written to the command file (lspost.cfile). These can be filtered out by setting "Record Orient off" in the Toggle Menu.
