If you're in Emacs 28 or higher, the former is already enabled +and all you need is the familiar + +@lisp +M-x install-package RET geiser-guile RET +@end lisp + +That will also install geiser, and its fine info manual. Please refer +to it (or its @uref{https://geiser.nongnu.org, online version}) for a general description of how geiser +schemes work. We provide below some additional details specific to +geiser-guile. + +@node Start up +@unnumbered Start up + +When launching the Guile REPL, geiser will invoke the binary +configured in @code{geiser-guile-binary} (simply "guile" by default) +which in turn will load @code{geiser-guile-init-file}, if any. + +Note, however, that specifying @code{geiser-guile-init-file} is @emph{not} +equivalent to changing Guile's initialization file (@samp{~/.guile}), +because the former is loaded using the @samp{-l} flag, together with @samp{-q} +to disable loading the second. But there are subtle differences +in the way Guile loads the initialization file versus how it loads +a file specified via the @samp{-l} flag. If what you want is just +loading @samp{~/.guile}, leave @code{geiser-guile-init-file} alone and set +@code{geiser-guile-load-init-file-p} to @code{t} instead. + +One can also provide a global list of paths to add to Guile's +@samp{%load-path} via @code{geiser-guile-load-path}. + +@node Debugging support +@unnumbered Debugging support + +Guile supports all the debugger commands supported by Geiser (it's +in fact used as the reference for the implementation and design of +that support). When the REPL would normally enter its debug mode, +with a prompt of the style: + +scheme@@(guile-user) [1]> + +showing a debugging level, Geiser will instead bring you to the +@samp{*Geiser Dbg*} buffer, where you can access a menu of debugging +commands via the @code{,} (comma) key. + +The geiser-guile customization group will show you, among many +other, a few flags fine-tuning interaction with the debugger, as +well as things like the detail level of error messages (e.g. via +@code{geiser-guile-warning-level}). + +@node Tramp support +@unnumbered Tramp support + +Geiser guile can be used remotely via tramp connections: the REPL +process will be run in the machine where the tramp-accessed file +lives. Implemented by Felipe Lema. + +@bye
