Configuring Guile for G-Golf ¶

The following description and content is shared and identical to the ‘Merging Generics’ heading of the previous section.

It is repeated it here, under its own section entry, so that it appears in the table of content and grab all users attention - those who do not follow our recommendation may void their warranty or poison their cat.

  ^_ Merging Generics

In G-Golf, generic functions are always merged (see Merging Generics in The GNU Guile Reference Manual).

Users are (highly) recommended to do the same, in their repl, application/library modules and script(s). In its modules - those that import (oop goops) - G-Golf uses the following duplicate binding handler set:

  #:duplicates (merge-generics
		replace
		warn-override-core
		warn
		last)

In a repl or in scripts, these maybe set - after importing (oop goops) - by calling default-duplicate-binding-handler:

(use-modules (oop goops))

(default-duplicate-binding-handler
    '(merge-generics replace warn-override-core warn last))

G-Golf regular users should consider adding the above lines to their $HOME/.guile or, when working in a multi-user environmet, should consider adding those lines the file named init.scm in the so-called Guile global site directory¹⁰, here (evaluate the following expression in a terminal): guile -c "(display (%global-site-dir))(newline)".
