Methods for examining large/complicated lisp objects

Folding code between a literal "begin"/"end" block using Hideshow

A formatted input file (*.alm) often contains a large section of columned data. To fold this and improve navigation, I've tried to implement a hs-special-mode-alist entry from hideshow.el. (setq hs-special-modes-alist '((alamo-mode "begin_data"…

hiding and showing all blocks with one binding

I want to combine the commands hs-hide-all and hs-show-all. It would be great if I'd have a function that detects the "status" of all blocks. If there are blocks that aren't hidden, the function should hide them, thus all blocks are hidden. Applying…

I've got emacs' HideShow mode working well with Perl code (let's face it, it's a doddle), but I don't know if it's even possible to get it to fold POD comments as well. Has anyone done this (and if so, how, please)? (Note: when asked about this on…

Sorry about the title, I don't know how to describe it better. Using display-line-numbers-mode with hs-hide-all to edit a Common Lisp file, I see the line number moving to the right, which is quite distracting and annoying. How could I prevent that…
