Updates: 1. breadline installed out of the box, no extra effort required, on SLES11 at work. 2. breadline did exactly what I expected when I added (repl) to the code in the given csirc example and put it in my program. 3. ^R, history saving and all the other powerful features of readline all seem to work. 4. Code completion works!! Maybe it is a bit much to ask but it'd be useful if completion rolled over from internal symbols to files. (*)
Thanks Vasilij, this egg is very much appreciated. If no one else is reporting problems on Ubuntu 18.04 then likely I've got something messed up on my home machine. I'll debug further and report back on what I find. This is what I included in my code to get a repl with line editing, history etc: (case command ((repl) (import (chicken load)) (load-verbose #f) (let () (import (chicken format)) (import (chicken process-context)) (unless (get-environment-variable "INSIDE_EMACS") (import breadline) (import breadline-scheme-completion) (history-file (format "~a/.csi_history" (get-environment-variable "HOME"))) (stifle-history! 10000) (completer-word-break-characters-set! "\"\'`;|(") (completer-set! scheme-completer) (basic-quote-characters-set! "\"|") (variable-bind! "blink-matching-paren" "on") (paren-blink-timeout-set! 200000) (current-input-port (make-readline-port)))) (repl) ;; added this ) . . . (*) What I mean by rollover is this: #;> (publis<tab> ;; fills out from internal symbols and the publish is filled out. Then I'd like to enter a filename: #;> (publish "examples/a<tab> ;; if breadline doesn't find an internal symbol "examples/a" then it could look at the filesystem and list the files that match.
