Emacs

The contents of this section assumes that you installed geiser, and optionally racket-mode and company-mode.

1. Open a racket file (.rkt), and do C-c ! or M-x geiser-mode-switch-to-repl.
2. Typing C-c ! again in the racket buffer will switch to existing REPL buffer if any.
3. In the REPL buffer, pressing C-c C-m or M-x switch-to-geiser-module, and enter "filename.rkt" to switch to that module. (With double-quotation!).
   • Swithing to module may fail if the REPL process cannot parse the buffer content properly.
   • Note that C-c C-m only works in the REPL buffer, not a racket buffer.
   • Unless the REPL switched to proper module, you may not access evaluated result.
   • Or, you could use ,enter "FILENAME" in the REPL buffer.
4. You can optionally enable company-mode for the auto-completion feature.
5. To terminate REPL process, press C-c C-q in the REPL buffer.

Here's list of eval commands available to a racket buffer:

• C-x C-e -- geiser-eval-last-sexp
• C-c C-b -- geiser-eval-buffer
• C-c C-r -- geiser-eval-region

You can browse the manual in a racket buffer:

• C-c C-d TAB geiser-doc-look-up-manual open racket reference manual (possible through a web browser) at point.
• C-c C-d d geiser-doc-symbol-at-point open other buffer for the docstring
