lurk-emacs

Emacs IDE functionality for lurk

Installation

There are two packages available in the MELPA package repository:

• lurk-mode for code highlighting and REPL interaction
• ob-lurk for using lurk code snippets in org-mode documents

See MELPA's getting started to get connected to their repository. Once you've done that, you can run

M-x package-install lurk-mode

and if you also want org-mode functionality,

M-x package-install ob-lurk

Configuration

If lurkrs is installed on your PATH, you don't need to change anything.

If it isn't, run M-x customize-variable RET, lurk-executable RET, enter the location of your lurk binary, eg /home/user/lurk-rs/target/release/lurkrs, and save the changes.

Usage

Start a REPL

Run M-x lurk-repl.

Evaluate expressions

In a .lurk source file, you can run M-x lurk-eval-last-expression to evaluate the given expression preceding point. The result will be shown in the repl buffer.

Org-babel

You can use lurk code snippets in org files as follows:

#+begin_src lurk
  (+ 1 1)
#+end_src

You can execute the code blocks the same as any other org-babel snippet, C-c C-c.

You'll see this appear below the code snippet:

#+RESULTS:
: Lurk REPL welcomes you.
: > [3 iterations] => 2
: > Exiting...
