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: +% $ROOTDIR/erts/etc/unix/etp-commands +% Also, erl and erlc must be in the path. +%--------------------------------------------------------------------------- +end + +############################################################################ +# Toplevel commands +# + +define etp +# Args: Eterm +# +# Reentrant +# + etp-1 ((Eterm)($arg0)) 0 + printf ".\n" +end + +document etp +%--------------------------------------------------------------------------- +% etp Eterm +% +% Takes a toplevel Erlang term and prints the whole deep term +% very much as in Erlang itself.
