BatchWindows

BatchWindows is the window renderer used in Shivtanium.

It uses set /p for input. By default, it's started with an open file for input; Along with the Shivtanium Kernel being able to launch applications with set-up pipes, Everything printed to stdout in Shivtanium apps is redirected to BatchWindows.

Syntax

Note that the spaces between arguments are <tab>. In this way, you can input spaces into (for example) the Window Title.

Creating windows

¤CW <ID> <x> <y> <width> <height> <title> [<themes>]

• ID - The window ID.
• x, y - The window position on the console. Can be changed later.
• width, height - The window size. Minimum size: 12, 3
• title - The window title. (Note: Escape sequences in the title are not supported.)
• themes - The window theme(s). Themes are loaded from the resource pack's themes folder. Multiple themes can be seperated by spaces. The reason why you would want more than 1 theme on a window is because there are special themes called "Thememods" which can disable the control UI, unfocused alternative colors, and more.

Modifying windows

There are 2 ways to modify a window. The first method can accept multiple attributes in a single command, but it uses unsafe expansion and it can get slow:

¤MW <ID> <attribute>=<value> <another attribute>=<value> ...

• attribute - A window attribute. Windows have a wide selection of attributes; Some examples might help:

  • x, y - The window position on the console.
  • l<n> - Text on line <n>.
  • o<n> - Overlay on line <n>. Can be used for buttons & text inputs.

The second way properly handles all special characters, but it accepts only 1 attribute and it doesn't re-draw the window. For that, you'll need to finally use the ¤MW command;

¤TW <ID> <attribute>=<value>

• The parameters work in the same way as in the command above.

Example: ¤MW <ID> l2= Hello, world. - Displays Hello, world. on line 2. (The 2 spaces are for padding)

Controlling windows

• ¤FOCUS <ID> - Focuses a window by it's ID.
• ¤CTRL MINIMIZE <ID> - Minimizes / hides a window by it's ID.
• ¤CTRL RESTORE <ID> - Restores / shows a window by it's ID.
• ¤CTRL ORDER <Order of windows> - Hides all windows and only displays the specified windows. Can be used to change the order of windows.

Other features

• ¤CTRL APPLYTHEME <Theme ID> - Applies a loaded theme and changes the background if the theme has one. This doesn't change windows with a pre-specified theme.
• ¤CTRL BSOD <cause> <message> - Shows a blue screen of death in the console and exits. Can be used for a crash handeler.
• ¤CTRL PAUSE - Completely freezes DWM and ignores all input until the following message which also resumes it: ¤CTRL RESUME
• ¤EXIT - Stops DWM
