NAME NetHack::Menu - interact with NetHack's menus VERSION Version 0.04 released 09 Dec 07 SYNOPSIS use NetHack::Menu; my $menu = NetHack::Menu->new(vt => $term_vt102); # compile all pages of the menu until ($menu->at_end) { $term_vt102->process($nh->send_and_recv($menu->next)); } # we want to stuff all blessed items into our bag $menu->select(sub { /blessed/ }); # but we don't want things that will make our bag explode $menu->deselect(sub { /cancell|bag.*(holding|tricks)/ }); $term_vt102->process($nh->send_and_recv($menu->commit)); DESCRIPTION NetHack requires a lot of menu management. This module aims to alleviate the difficulty of parsing and interacting with menus. This module is meant to be as general and flexible as possible. You just give it a Term::VT102 object, send the commands it gives you to NetHack, and update the Term::VT102 object. Your code should look roughly the same as the code given in the Synopsis. METHODS new (vt => Term::VT102, select_count => (none|single|multi)) -> "NetHack::Menu" Takes a Term::VT102 (or a behaving subclass, such as Term::VT102::Boundless or Term::VT102::ZeroBased). Also takes an optional "select_count" which determines the type of menu. "NetHack::Menu" cannot intuit it by itself, it depends on the application to know what it is dealing with. Default: "multi". select_count [none|single|multi] -> (none|single|multi) Accessor for "select_count". Default: "multi". has_menu -> Bool Is there currently a menu on the screen? at_end -> Bool This will return whether we've finished compiling the menu. This must be called for each page because this is what does all the compilation. Note that if there's no menu, this will "croak". next -> Str Returns the string to be used to get to the next page. Note that you should not ignore this method and use ">" or a space if your menu may not start on page 1. This method will make sure everything is hunky-dory anyway, so you should still use it. select Code Evaluates the code for each item on the menu and selects those which produce a true value. The code ref receives $_ as the text of the item (e.g. "a blessed +1 quarterstaff (weapon in hands)"). The code ref also receives the item's selector (the character you'd type to toggle the item) as an argument. Note that you can stack up multiple selects (and deselects) before eventually finishing the menu with "$menu->commit". Do note that selecting is not the same as toggling. This currently returns no useful value. deselect Code Same as select, but different in the expected way. ":)" commit -> Str This will return the string to be sent that will navigate the menu and toggle the requested items. TODO * Not everyone uses the default "^", "|", and ">" menu accelerators. Provide a way to change them. * Not everyone uses Term::VT102. Provide some way to pass in just a string or something. This will be added on an if-needed basis. Anyone?
