Backseat Debug

Backseat (bslang, .bs) and Bssembler (.bsm) – debugger for Bssembler and syntax highlighting for both.

This project is still a work in progress as are the backseat language and its platforms. Debugging is only implemented for .bsm files so far.

Features

• Debugging Bssembler (.bsm) files.
  • Stopping on breakpoints and/or on entry.
  • Stepping through application line by line.
  • Displaying register values.
  • Changing register values.
  • Displaying a call stack.
• Bssembler syntax highlighting
• Backseat (bslang) syntax highlighting

Requirements

The debugger requires a bssembler and emulator to be able to debug .bsm files. For both windows/x64 binaries are packaged with the extension.

If you want to run the debugger on other platforms you can build bssembler and emulator yourself and specify their path in the launch.json file or in your settings. Make sure to build the emulator with debugging features (e.g. cargo build --features debbuger).

Extension Settings

This extension contributes the following settings:

• backseat-debug.bssemblerExternalPath: Specifies an external bssembler to be used. The bssembler has to support the '-m' CLI option.
• backseat-debug.emulatorExternalPath: Specifies an external emulator to be used. The emulator has to support the debug interface over TCP.
• backseat-debug.emulatorExternalPathNoGraphics: Specifies an external emulator without graphics to be used. The emulator has to support the debug interface over TCP.
• backseat-debug.bssemblerDefaultCommand: Command with arguments for external bssembler that should be used if no bssemblerCommand is specified. This setting overrules backseat-debug.bssemblerExternalPath.
• backseat-debug.emulatorDefaultCommand: Command with arguments for external emulator that should be used if no emulatorCommand is specified. This setting overrules backseat-debug.emulatorExternalPath.
• backseat-debug.bssemblerTimeout: Time in milliseconds after which the bssembler is killed if it does not terminate.
• backseat-debug.emulatorTimeout: Time in milliseconds after which the emulator is killed if debugger cannot be connected.
