Andy Wingo 33df2ec719 integrate the debugger into the repl ... * module/system/repl/debug.scm: New file, defines a data type to hold state for a debugger stack, and some helper procedures to print the stack or print a frame. Most pieces are from (system vm debug). * module/system/repl/error-handling.scm: New file, implements call-with-error-handling and with-error-handling, and instead of going into a debugger, we go into a recursive repl that happens to have debugging information. Will be removing the old debugger from (system vm debug) shortly. * module/Makefile.am (SYSTEM_SOURCES): Add error-handling and debug scm files. * module/system/repl/repl.scm (prompting-meta-read): Better error handling -- we don't want to go into a debugger when reading a command. (start-repl): Add #:debug keyword argument, and just dispatch to run-repl. (run-repl): New function, with the guts of the old start-repl. Added a prompt, to which a throw to 'quit will abort. * module/system/repl/common.scm (repl-prepare-eval-thunk): New helper. In the future we will use this to not enter the debugger on errors that happen at compile time. (repl-eval): Use repl-prepare-eval-thunk. (repl-print): Run the before-print-hook when printing a value. * module/system/repl/command.scm (*command-table*): Move `option' to the `system' group. Move `trace' to the `profile' group. Add `debug' and `inspect' groups. (command-abbrevs): Rename from command-abbrev, and allow multiple abbreviations. (display-group): Fix the case where abbrev? was #f. (display-summary): Fix alignment of the command and abbreviations. Allow multiple abbreviations. (read-command): Rename from read-datum, and have better error handling. (meta-command): Better error handling. (define-meta-command): Better error handling. (help, show, import, compile, disassemble, time, profile, trace): Fix docstrings and error messages. (define-stack-command): New helper, for commands that operate on a saved stack. (backtrace, up, down, frame, procedure, locals): New debugger commands, in the REPL now. (inspect, pretty-print): New "inspect" commands.		2010-07-09 17:05:25 +02:00
