Seen in: guile (GNU Guile) 2.2.4 When using the with-readline-completion-function, the passed readline uses the default (apropos) completion function instead of the one provided to with-readline-completion-function.
I believe that this is because root/guile-readline/ice-9/readline.scm has defined with-readline-completion-function as a function instead of as a macro. The readline provided in thunk is executed before the body of with-readline-completion-function executes and overrides *readline-completion-function*. As an aside, I think the API would be better if the completion function could be provided to readline directly. Attached is a sample program. Below is sample output of a run of the attached program. You can see that it's autocompleting Guile functions and variables (the default apropos completion) rather than the provided one which should have had only 3 options with just one starting in "th". ;;;;;;;;;;;;;;;;;;;;;;;;;;; Prompt: Display all 1859 possibilities?
