NAME

6       feathers - a simple source-level debugger for CHICKEN Scheme
7
8

SYNOPSIS

10       feathers [OPTION ...] [PROGRAM ARGUMENTS ...]
11
12

DESCRIPTION

14       feathers  runs  a program compiled with CHICKEN Scheme and allows basic
15       source-level debugging like setting  breakpoints,  single-stepping  and
16       inspection of procedure arguments and global variables.
17
18       The Scheme code must be compiled with debug-level 3 for debugging to be
19       possible. Communication with the debugger  takes  place  by  exchanging
20       messages  over  a  TCP  socket, the address and port being given by the
21       environment variable CHICKEN_DEBUGGER which holds a connection  address
22       of the form <ADDRESS>:<PORT>

ENVIRONMENT VARIABLES

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