guix repl command makes it easier to program Guix in Guile by
launching a Guile read-eval-print loop (REPL) for interactive
programming (see Using Guile Interactively in GNU Guile Reference
Manual), or by running Guile scripts (see Running Guile Scripts in GNU Guile Reference Manual). Compared to just launching the
guix repl guarantees that all the Guix
modules and all its dependencies are available in the search path.
guix repl options [file args]
When a file argument is provided, file is executed as a Guile scripts:
guix repl my-script.scm
To pass arguments to the script, use
-- to prevent them from being
interpreted as arguments to
guix repl itself:
guix repl -- my-script.scm --input=foo.txt
To make a script executable directly from the shell, using the guix executable that is on the user’s search path, add the following two lines at the top of the script:
#!/usr/bin/env -S guix repl --
Without a file name argument, a Guile REPL is started:
$ guix repl scheme@(guile-user)> ,use (gnu packages base) scheme@(guile-user)> coreutils $1 = #<package email@example.com gnu/packages/base.scm:327 3e28300>
guix repl implements a simple machine-readable REPL
protocol for use by
(guix inferior), a facility to interact with
inferiors, separate processes running a potentially different revision
The available options are as follows:
Start a REPL of the given TYPE, which can be one of the following:
This is default, and it spawns a standard full-featured Guile REPL.
Spawn a REPL that uses the machine-readable protocol. This is the protocol
(guix inferior) module speaks.
guix repl reads from standard input and writes to
standard output. When this option is passed, it will instead listen for
connections on endpoint. Here are examples of valid options:
Accept connections on localhost on port 37146.
Accept connections on the Unix-domain socket /tmp/socket.
Add directory to the front of the package module search path (see Пакетные модули).
This allows users to define their own packages and make them visible to the script or REPL.
Inhibit loading of the ~/.guile file. By default, that configuration
file is loaded when spawning a
