NonGNU ELPA: inf-clojure

This package provides basic interaction with a Clojure subprocess (REPL).
It's based on ideas from the popular `inferior-lisp` package.

`inf-clojure` has two components - a nice Clojure REPL (`inf-clojure-mode`)
and a minor mode (`inf-clojure-minor-mode`), which extends `clojure-mode`
with commands to evaluate forms directly in the REPL.

`inf-clojure` provides a set of essential features for interactive
Clojure/ClojureScript/ClojureCLR development:

* REPL
* Interactive code evaluation
* Code completion
* Definition lookup
* Documentation lookup
* ElDoc
* Apropos
* Macroexpansion
* Namespace reloading
* Connecting to socket REPLs

It supports many Clojure runtimes including Clojure (JVM), ClojureScript,
ClojureCLR, babashka, Planck, and Joker.

Changelog

master (unreleased)

3.4.0 (2026-02-27)

New features

• #57: Add inf-clojure-show-var-meta command (C-c C-S-m) to display a var's metadata.
• #205: Add inf-clojure-eval-ns-aware option for namespace-aware evaluation.

Changes

• Unify reload and reload-all forms with inf-clojure-repl-features, enabling per-REPL-type dispatch. The standalone inf-clojure-reload-form and inf-clojure-reload-all-form defcustoms have been removed.
• Deduplicate Clojure-family REPL feature definitions via a shared base alist.
• #143: inf-clojure-show-arglists now displays results in the REPL buffer instead of the minibuffer.
• Drop support for lein-clr (abandonware).
• Use the modern eldoc-documentation-functions hook instead of the deprecated eldoc-documentation-function.
• Remove unused inf-clojure-chomp function.

Bugs fixed

• Fix inf-clojure-connected-p to check for a live process.
• Fix truncated autoload cookie on inf-clojure-connect.
• Fix prefix-arg vs current-prefix-arg in REPL startup.
• Fix inf-clojure--clojure-buffer-p to work on Emacs 28-29 (derived-mode-p does not accept a list before Emacs 30).
• #219: Fix project-root error when no project is detected (e.g. Squint REPL outside a project).
• #136: Fix preoutput filter to handle chunked comint output correctly, preventing spurious newlines (#153) and improving reliability of output filtering.
• Fix node-babashka auto-detection by adding its startup form entry.
• #149: Show confirmation message after inf-clojure-set-ns.

3.3.0 (2025-05-25)

New features

• #202: Add ClojureCLR support.
• #210 Include inf-clojure-socket-repl to create a socket REPL and connect to it from inside Emacs.
• #217: Add clojure-ts-mode support.

Changes

• Improve support for multiple forms in the same line by replacing beginning-of-defun fn.
• #204: Scroll repl buffer on insert commands
• #208 Display message after setting REPL.
• Require Emacs 28.
• Drop support for Lumo.

3.2.1 (2022-07-22)

Bugs fixed

• Address some small issues with NonGNU ELPA (e.g. missing maintainer metadata).

3.2.0 (2022-07-15)

New features

• #168: New helper function inf-clojure-switch-to-recent-buffer to select the last buffer an inf-clojure process buffer was swapped to from.
• #187: New defcustom inf-clojure-enable-eldoc to disable eldoc interaction.

Bugs fixed

• #185: Improve cmd string splitting.
• #193: Set syntax table in REPL buffer.
• Fix inf-clojure-display-version (it wasn't extracting properly the package version).

3.1.0 (2021-07-23)

New features

• #190: Helper function inf-clojure-set-repl to select inf-clojure process buffer.
• Auto-enable inf-clojure-minor-mode after invoking inf-clojure. This behaviour is controlled via inf-clojure-auto-mode.
• Include the project name automatically in the REPL buffer name.

Bugs fixed

• #152: Sanitize should only remove whitespace at the end of a command.
• #188: Handle newlines between forms for inf-clojure-eval-buffer. ... ...
