With some exploration, I figured out I can make the popup work again by doing the following from inside *Guix Internal REPL*:
``` scheme@(emacs-guix)> ,m (guix gexp) scheme@(guix gexp)> (read-hash-extend #\~ read-gexp) (read-hash-extend #\$ read-ungexp) (read-hash-extend #\+ (cut read-ungexp <> <> #t)) $12 = ((#\. . #<procedure 7f4a564aa3d0 at ice-9/boot-9.scm:2251:18 (c port)>)) $13 = ((#\~ . #<procedure read-gexp (chr port)>) (#\. . #<procedure 7f4a564aa3d0 at ice-9/boot-9.scm:2251:18 (c port)>)) $14 = ((#\$ . #<procedure read-ungexp (chr port #:optional native?)>) (#\~ . #<procedure read-gexp (chr port)>) (#\. . #<procedure 7f4a564aa3d0 at ice-9/boot-9.scm:2251:18 (c port)>)) scheme@(guix gexp)> ,m emacs-guix ``` I.e., if I drop into the (guix gexp) and run read-hash-extend myself. After that, I can successfully run M-x guix c. (The popup itself seems to have something else wrong with it, but we'll leave that for another bug report...) It seems worth noting that I do have access to other variables and such inside the eval-when block, though I'm not sure what that tells us: ``` scheme@(emacs-guix)> ,m (guix gexp) scheme@(guix gexp)> read-syntax-redefined? $15 = #t ``` -- Christopher Howard
