When you use geiser-load-file (check its definition in geiser-compile.el), any output from that command is parsed as an evaluation response, and not displayed in the repl. If you want to capture messages you could use the low-level geiser-eval--send/wait, and process its result. Maybe Guile's startup function(s) will give you an idea of how: https://gitlab.com/emacs-geiser/guile/-/blob/master/geiser-guile.el#L379 there, guile is setting a variable, not loading anything, but the idea would be the same: you specify a form to evaluate that loads the file (the 'code'), use geiser-eval--send/wait, and parse its result (the message will be under a key named "output")... that, however, won't print that message in the REPL buffer by itself, you'd need to. But i am thinking that a much easier way to do this might be simply to invoke gxi with flags to the effect of loading the file you're interested in. You can specify a 'binary' function that computes them. The advantage is that, when calling the binary (with any flags), stdout is still redirected to the REPL. See https://gitlab.com/emacs-geiser/guile/-/blob/master/geiser-guile.el#L139 https://gitlab.com/emacs-geiser/guile/-/blob/master/geiser-guile.el#L430 (the value returned by the 'binary' method can be a list, instead of a single string).
