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

- -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
