emacs - 将 chezschme 设置为 geiser-default-implementation

Question

我安装了chezscheme

$ chezscheme
Chez Scheme Version 9.5
Copyright 1984-2017 Cisco Systems, Inc.

> (define a (list 4 5 6 ))
> (set-car! a 9)
> a
(9 5 6)

并将其配置为 geiser-default-implementation

(require 'geiser)
(setq geiser-active-implementations '(chez guile racket chicken mit chibi gambit))
(add-hook 'scheme-mode-hook 'geiser-mode)
(setq geiser-default-implementation 'chez)

尽管如此，当使用 org src 发出 C-c C-c

#+begin_src scheme :session sicp :lexical t
(define a (list 2 3 4))
(set-car! a 9)
a
#+end_src

#+RESULTS:

它缓冲了很长时间，提示在迷你缓冲区中“chez go and up”

但改为运行 MIT-scheme。

错误:

MIT/GNU Scheme running under GNU/Linux
Type `^C' (control-C) followed by `H' to obtain information about interrupts.

额外的:

添加 geiser-chez-binary

(setq geiser-active-implementations '(chez guile))
(setq geiser-chez-binary "chez")
(add-hook 'scheme-mode-hook 'geiser-mode)
(setq geiser-default-implementation 'chez)

并运行

#+begin_src scheme   :session sicp :lexical t :results output
(define b (list 3 4))

#+end_src

它报告

    apply: Searching for program: No such file or directory, chez

然后我附加 chez至 org-babel-do-load-languages并将关键字方案更改为 chez

#+begin_src chez   :session sicp :lexical t :results output
(define b (list 3 4))

#+end_src

它报告:

  No org-babel-execute function for chez!

删除了 mit-scheme 包，它可以工作

默认情况下，Geiser 认为 Chez Scheme 的可执行文件是 scheme ，然而，事实并非如此，Chez Scheme 使用 chez和 Mit Scheme 使用 scheme和 mit-scheme .您需要将以下内容放入您的 Emacs init 文件中:

(setq geiser-chez-binary "chez")

这是 geiser-chez-binary的文档字符串(我已经将其更改为 chez):

geiser-chez-binary is a variable defined in `geiser-chez.el'.
Its value is "chez"
Original value was "scheme"

Documentation:
Name to use to call the Chez Scheme executable when starting a REPL.

You can customize this variable.
