feathers — a simple source-level debugger for CHICKEN Scheme

Synopsis

feathers [OPTION ...] [PROGRAM ARGUMENTS ...]

Description

feathers runs a program compiled with CHICKEN Scheme and allows basic source-level debugging like setting breakpoints, single-stepping and inspection of procedure arguments and global variables.

The Scheme code must be compiled with debug-level 3 for debugging to be possible. Communication with the debugger takes place by exchanging messages over a TCP socket, the address and port being given by the environment variable CHICKEN_DEBUGGER which holds a connection address of the form <ADDRESS>:<PORT>

Options

-help
Shows a list of supported command-line options.
-n
Do not load the default startup file .feathers
-port PORT
Select a different TCP port than the default (9999)
-dir DIRECTORY
Add DIRECTORY to the list of searched paths for locating source files

Environment Variables

CHICKEN_DEBUGGER
Should hold a TCP server address and port where the debugger is listening. This variable is set by the debugger when a program is run from it, and defaults to localhost:9999
