細胞模式

Question

說我有一個代碼緩衝器（在這種情況下Python）的組織如下：

.. cell 1 .. 
## 
.. cell 2 .. 

# this is a comment 

### this is also a comment 

.. still cell 2 .. 

    ## 
    .. cell 3 (code that is indented) 

字符##的序列是指在緩衝器來分隔cells（代碼區域/塊） 。字符#在Python中開始評論，因此##被視爲該語言的評論。類似的結構可以建立在例如Elisp與;;或其他編程語言。

我想限定Emacs的命令在調用時，它定義了當前cell（其上point /光標當前位於即cell。）是Emacs的region（即它突出的小區） 。

我該如何在Emacs中做到這一點？

參考：

• 的類似於細胞在MATLAB
• 這裏的概念或code sections是用於實現在Vim的此功能的thread。

這裏有一個解決方案：

(defun python-inside-comment-p() 
    (save-excursion 
    (beginning-of-line 1) 
    (looking-at "^#"))) 

(defun python-select-cell() 
    (interactive) 
    (goto-char 
    (if (re-search-backward "^\\s-*##[^#]" nil t) 
     (match-end 0) 
    (point-min))) 
    (while (and (python-inside-comment-p) 
       (eq 0 (forward-line 1))) 
    nil) 
    (set-mark (point)) 
    (goto-char 
    (if (re-search-forward "^\\s-*\\(##[^#]\\)" nil t) 
     (- (match-beginning 1) 2) 
    (point-max)))) 

測試了：

print "Beautiful is better than ugly." 
## 
print "Explicit is better than implicit." 
print "Simple is better than complex." 
print "Complex is better than complicated." 
# this is a comment 
print "Flat is better than nested." 
### this is also a comment 
print "Sparse is better than dense." 
## 
print "Readability counts." 
print "Special cases aren't special enough to break the rules." 
print "Although practicality beats purity." 
print "Errors should never pass silently." 
print "Unless explicitly silenced." 

工程確定。 是否有理由不使用縮進級別而不是評論作爲錨點？

Answer 2

這將是這樣的：

(defun mark-cell() 
    (interactive) 
    (search-backward-regexp "^##\\($\\|[^#]\\)" nil 'noerror) 
    (push-mark) 
    (end-of-line) 
    (search-forward-regexp "^##\\($\\|[^#]\\)" nil 'noerror) 
    (beginning-of-line) 
    (activate-mark)) 

對於我來說，它並不突出的細胞（可以手動做到這一點與CXCX），即使那是什麼activate-mark應該這樣做，如果我理解正確。

從EmacsWiki，有兩個包：

python-x還提供了一些額外的功能

python-cell提供Matlab的樣細胞蟒蛇緩衝區
