如何在 Common Lisp 中写入 zip 文件？
我可以打开 zip 条目并调整内容，但我不知道如何保存它们。
需要 CL ZIP 的 API。
规格：
ZIP
Quicklisp
MacPorts CLISP 2.49
Aquamacs 2.1 (Emacs 23.2)
Mac OS X 10.6.4
MacBook Pro 5,1

(ql:quickload "zip")
(ql:quickload "cl-ppcre")
(defvar *epub* nil)
(defvar *epub-contents* nil)
(defvar *epub-out* nil)
(defun load-epub (filename)
(setq *epub* (zip:open-zipfile filename)))
(defun close-epub ()
(zip:close-zipfile *epub*)
(setq *epub* nil)
(setq *epub-contents* nil))
(defun gather-epub-contents ()
(zip:do-zipfile-entries (name entry *epub*)
(push name *epub-contents*)))
(defun is-html-file (name)
(if (cl-ppcre:scan ".+\\.htm[l]?$" name) t nil))
(defun entry-name-to-html (name)
(flexi-streams:octets-to-string
(zip:zipfile-entry-contents
(zip:get-zipfile-entry name *epub*))))
(defun clean (html)
(values
(cl-ppcre:regex-replace-all
"<pre[^>]*>(\\s)*"
(cl-ppcre:regex-replace-all "\\s+</pre>" html "</pre>")
"<pre>")))
I'm able to open a zip entry and tweak the contents, but I can't figure out how to save them.
The API for CL ZIP is wanting.

根据 Common Lisp ZIP 库的文档，您必须获取单独的句柄才能写入 zip 文件。也许您可以将内容提取到文件夹中，调整内容并通过一次调用
（zip路径名源文件夹）来压缩整个文件夹。As per the documentation of the Common Lisp ZIP library, you have to obtain a separate handle to write to the zip file. Probably you can extract the contents to a folder, tweak the contents and compress the whole folder with a single call to
(zip path-name source-folder).使用临时文件，您可以解压缩、修改和重新压缩。
请参阅 sigil-clean.cl
Using a temp file, you're able to unzip, modify, and rezip.
See sigil-clean.cl
