% etp-help
%
% Same as "help etp-help"
%
% Emulator Toolbox for Pathologists
% - GDB command toolbox for analyzing core dumps from the
% Erlang emulator (BEAM).
%
% Should work for 32-bit erts-5.2/R9B, ...
%
% The commands are prefixed with:
% etp: Acronym for erts-term-print
% etpf: Acronym for erts-term-print-flat
%
% User commands (these have help themselves):
%
% Most useful:
% etp, etpf
%
% Useful for doing step-by-step traversal of lists and tuples after
% calling the toplevel command etpf:
% etpf-cons, etpf-boxed,
%
% Special commands for not really terms:
% etp-mfa, etp-cp,
% etp-msgq, etpf-msgq,
% etp-stacktrace, etp-stackdump, etpf-stackdump, etp-dictdump
% etp-offheapdump, etpf-offheapdump,
% etp-print-procs, etp-search-heaps, etp-search-alloc,
% etp-ets-tables, etp-ets-tabledump
%
% Complex commands that use the Erlang support module.
% etp-overlapped-heaps, etp-chart, etp-chart-start, etp-chart-end
%
% Erlang support module handling commands:
% etp-run
%
% Parameter handling commands:
% etp-show, etp-set-max-depth, etp-set-max-string-length
%
% Other commands you may find in this toolbox are suffixed -1, -2, ...
% and are internal; not for the console user.
%
% The Erlang support module requires `erl' and `erlc' in the path.
% The compiled "erl_commands.beam" file is stored in the current
% working directory, so it is thereby in the search path of `erl'.
%
% These are just helpful commands when analyzing core dumps, but
% you will not get away without knowing the gory details of the
% tag bits. Do not forget about the e.g p, p/x, x and x/4x commands.
%
% Execution speed of user defined gdb commands is not lightning fast.
% It may well take half a minute to dump a complex term with the default
% max depth values on our old Sparc Ultra-10's.
%
% To use the Erlang support module, the environment variable ROOTDIR
% must be set to the toplevel installation directory of Erlang/OTP,
% so the etp-commands file becomes:
% $ROOTDIR/erts/etc/unix/etp-commands
% Also, erl and erlc must be in the path.
