好的,我没有找到更好的方法来做到这一点。但我确实决定将Javascript代码作为字符串嵌入到elisp模块中......工作得很好。
为了实现目标,我编写了一个简短的elisp函数,它创建了一个新的elisp模块。 它根据旧名称 - xxxx-bundle.el而不是xxxx.el选择一个新名称。然后它将原始.el文件中的内容写入具有新名称的文件中。然后它将一个简单的setq
语句写入同一个文件;整个JavaScript程序是该语句中的字面值。简化setq
的是elisp中的pp-to-string
函数,它将所有Javascript代码转换为适用于emacs的文字字符串。
的FN键生成包看起来像这样:
(defun jsshell-produce-bundle (&optional jsshell-el bundle-el jsshell-js)
"Produce a new .el file, which contains all the jsshell.el
function and also embeds the jsshell.js source as a string. The
resulting .el file will then be suitable for a one-file
distribution of JSShell.
JSShell depends on two pieces: jsshell.el and jsshell.js. Rather
than distributing and installing two distinct files, the bundle
embeds the .js file into the .el file, for a one-file
distribution option. This function produces that one file.
Most people will never need to use this function. It's useful only
after modifying either the original jsshell.el or the jsshell.js file,
when you want to produce a new distributable bundle. In other words, it's
useful for the developer of jsshell.el.

(let ((jsshell-el (or jsshell-el
(concat (file-name-directory jsshell--load-path) "jsshell.el")
"jsshell.el")))
(let ((bundle-el (or bundle-el
(concat (file-name-directory jsshell-el) "jsshell-bundle.el")))

jssrc)
(with-temp-file bundle-el
(insert (concat
";;; "
(file-name-nondirectory bundle-el)
" -- JSShell generated bundle\n"))
(insert (concat ";;\n;; generated " (current-time-string) "\n;;\n\n"))
(insert-file-contents jsshell-el)
(goto-char (point-max))
(insert "\n;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;\n")
(insert ";; this is the embedded Javascript code for the JS REPL\n\n")
(setq jssrc (jsshell--minimized-js-contents jsshell-js))
(goto-char (point-max))
(insert (concat "(setq jsshell-js-src "

助手FN键最小化内容只是崩溃的空白,消除了连续的换行符之类的事情。然后
所得.el文件可以引用该变量,jsshell-js-src
,它包含最小化的Javascript源。它看起来像这样:
,因为我觉得这种方法很可能是在其他模块也是有用的,我在这里张贴这一点 - 任何需要捆绑一个单独的数据文件。
