Print Untruncated Terms In The Shell
From Erlang Community
[edit] Overview
While in the shell, I frequently need to view some large term (let's call it X) such as a deep list. The shell usually truncates such a term. At this point many people, muttering darkly, are forced to type in io:format("~p\n", [X]). Isn't there a better way? As it turns out, yes: use the built-in shell function rp(Term). This is used to "display a Term using the shell's record information", according to the shell's help() function, but works for any Erlang term and has the side-effect of expanding the term fully.
[edit] Example
1> mnesia:start(), X = mnesia:system_info(all).
[{access_module,mnesia},
{auto_repair,true},
%% ++++ .... rows deleted for brevity ...
{schema_location,opt_disc},
{schema_version,...},
{...}|...] %% Arghhh!!!!
2> rp(X).
[{access_module,mnesia},
{auto_repair,true},
%% ++++ .... rows deleted for brevity ...
{schema_location,opt_disc},
{schema_version,{2,0}},
{subscribers,[<0.37.0>]},
{tables,[schema]},
{transaction_commits,2},
{transaction_failures,0},
{transaction_log_writes,0},
{transaction_restarts,0},
{transactions,[]},
{use_dir,false},
{core_dir,false},
{no_table_loaders,2},
{dc_dump_limit,4},
{version,"4.4.3"}]
