This document was based on my local GNU Guile-3.0.5 setup. I'm not sure if it works as is with an older version of GNU Guile.
Because of a dependency in Fedora I had to compile GNU Guile from source release. As such, in your local setup the paths will differ. This is only relevant when defining the GUILE shell variable, and referencing the tags file in the vimrc.
Note that when building GNU Guile from source be sure that you have the readline-devel (or distro equivalent package) installed. That way the
./configurestep will pick that up, and the
ice-9 readlinemodule will be usable.
Jump to the end if you want to see the setup in action.
If you're installing from source, you will want to set the variable
export GUILE=/path/to/guile explicitly
in your shell rc file (~/.bashrc, ~/.zshrc, etc). The
guild executable (which I have not used yet), relies
on this variable to detect the executable, as otherwise it defaults to
GNU Guile REPL configuration
When a new REPL instance is started, it will first evalute the contents of your
~/.guile file. This is where
you customize your REPL. I have currently just two modules enabled.
;; Adds all the goodness of GNU readline in the GNU Guile REPL. ;; If you're not familiar already with readline by name alone, it's a C library ;; that allows programs to expose a trully interactive command line, with history, ;; shortcuts, tab completion, etc. Just as if you'd be operating in a common shell. (use-modules (ice-9 readline)) (activate-readline) ;; Adds colour to the prompt and the result of evaluated s-expressions. ;; While it has no functional impact, it does make the REPL nicer to look at. ;; ;; You will need to download this module from https://gitlab.com/NalaGinrut/guile-colorized ;; ;; I just copied the contents of the colorized.scm file and dropped it in the ;; installed ~/.local/share/guile/3.0/ice-9/colorized.scm directory. ;; ;; Alternatively clone the repository and make GNU Guile aware of the new path. E.g ;; (add-to-load-path "/absolute/path/to/guile-colorized-clone") (use-modules (ice-9 colorized)) (activate-colorized)
As a vim user I had to spend a couple of hours researching different plugins, reddit posts, configurations and help pages to figure out how to set up a similar environment. I hope this result pops up for fellow vim users when they embark on the same Scheme journey.
Note to new vim users, for plugin management I use Vundle. If you're using another plugin to manage vim packages be sure to replace the
