[英]How to create a column view in Emacs Lisp?
I'm writing my own mode in Elisp. 我在Elisp中编写自己的模式。 It's basically a simple crud application showing rows of data which can be manipulated via the minibuffer. 它基本上是一个简单的crud应用程序,显示可以通过迷你缓冲区操作的数据行。 I'd like to create a view for these rows which looks like the emacs package manager: columns of data nicely aligned. 我想为这些行创建一个看起来像emacs包管理器的视图:数据列很好地对齐。 What's the best way to implement such a view? 实现这种观点的最佳方法是什么?
The answer from phils got me on track. phils的答案让我走上正轨。 There are no tutorials or simple examples anywhere though, so I created one. 虽然在任何地方都没有教程或简单的例子,所以我创建了一个。 Here is an example of a tabulated-list-mode derivative which has static data and can print the ID of the current column: 以下是具有静态数据并可打印当前列ID的列表列表模式衍生的示例:
(define-derived-mode mymode tabulated-list-mode "mymode" "Major mode My Mode, just a test"
(setq tabulated-list-format [("Col1" 18 t)
("Col2" 12 nil)
("Col3" 10 t)
("Col4" 0 nil)])
(setq tabulated-list-padding 2)
(setq tabulated-list-sort-key (cons "Col3" nil))
(tabulated-list-init-header))
(defun print-current-line-id ()
(interactive)
(message (concat "current line ID is: " (tabulated-list-get-id))))
(defun my-listing-command ()
(interactive)
(pop-to-buffer "*MY MODE*" nil)
(mymode)
(setq tabulated-list-entries (list
(list "1" ["1" "2" "3" "4"])
(list "2" ["a" "b" "c" "d"])))
(tabulated-list-print t))
If you look at the code for the package listing function you mention, you'll see that it employs package-menu-mode
which derives from tabulated-list-mode
. 如果你看一下你提到的软件包列表函数的代码,你会看到它采用了package-menu-mode
,它源自tabulated-list-mode
。
find-function
RET package-menu-mode
RET Mx find-function
RET package-menu-mode
RET tabulated-list-mode
RET Ch f tabulated-list-mode
RET I use org-mode for this kind of task all the time. 我一直使用org-mode来完成这种任务。
This should be a starting point for your development, because you already have nice tables. 这应该是您开发的起点,因为您已经有了很好的表。
