Helm-SLY

Helm for SLY, a Common Lisp interaction mode for Emacs.

Installation

Add helm-sly.el to your load-path. Set up SLY properly.

To use Helm instead of the Xref buffer, enable global-helm-sly-mode.

To enable Helm for completion, two options:

Without company:

(add-hook 'sly-mrepl-hook #'helm-sly-disable-internal-completion)
;; If you want fuzzy-matching:
(setq helm-completion-in-region-fuzzy-match t)

With company, install helm-company, then:

(add-hook 'sly-mrepl-hook #'company-mode)
(require 'helm-company)
(define-key sly-mrepl-mode-map (kbd "<tab>") 'helm-company)

Helm-SLY defines a few new commands:

helm-sly-list-connections: Yet another Lisp connection list with `helm’.
helm-sly-apropos: Yet another apropos with Helm.
helm-sly-mini: Like helm-sly-list-connections, but include an extra source of Lisp-related buffers, like the events buffer or the scratch buffer.

Fix predicate argument in helm-sly-lisp-buffer-source.
Fix buffer-less connection switching.
Rename helm-sly-build-buffers-source source name to “Build buffers”, to avoid conflict with Lisp buffers. This fixes completion against buffers.

Add source listing all Lisp buffers.
Make helm-sly–c-source-connection more customizable.
Include inferior Lisp buffer to the “Lisp buffers” source. It was already accessible via the action menu.
Dynamically list the debug buffer in the “Lisp buffers” source, when present. It was already accessible via the action menu.
Dynamically list sly-description and sly-compilation when present.
Fix sly-scratch and sly-db buffer switching.

New action to go to REPL in other window.
List current connection buffer candidate last.
Make connection candidates customizable. See helm-sly--c-source-connection.
Make connection candidate display customizable. See helm-sly-connection-formatter.
