elisp - Emacs: open large files in external apps automatically -


i use emacs file manager , open large file (in dired or speedbar) xdg-open. can use defadvice abort-if-file-too-large function , how correctly?

advising abort-if-file-too-large requires still raise error if opens file externally, otherwise find-file-noselect still try open file. also, want call external program when operation type passed abort-if-file-too-large indicates file being opened. following work, though might want tweak arguments call-process make fit scenario better:

(defun open-outside-emacs (orig-fun size op-type filename)   (if (not (string-equal op-type "open"))       (apply orig-fun size op-type filename)     (call-process "/usr/bin/xdg-open" nil 0 nil (expand-file-name filename))     (error "opened externally"))) (advice-add 'abort-if-file-too-large :around #'open-outside-emacs)

(side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
