[英]Notepad++ Automatic Detection of Python Tabs or Spaces
I normally write code with tabs but many python libraries use spaces. 我通常使用制表符编写代码,但许多python库使用空格。 Is there any way for Notepad++ to automatically detect how the file is formatted and have it automatically switch to using spaces when the file is already formatted that way?
Notepad ++是否有任何方法可以自动检测文件的格式,并在文件已经格式化时自动切换到使用空格?
BTW, I know there was already an SO question on how to change Notepad++'s tab format. 顺便说一句,我知道如何改变Notepad ++的标签格式已经有了一个问题 。 But it would be better if it automatically changed based on the current file's formatting.
但如果它根据当前文件的格式自动更改会更好。
If you install the "Python Script" plugin for Notepad++, you can write code to automatically switch between tabs and spaces. 如果为Notepad ++安装“Python Script”插件,则可以编写代码以自动在选项卡和空格之间切换。
Here's how: 这是如何做:
In the menu: Plugins -> Python Script -> Configuration, and set Initialization to ATSTARTUP. 在菜单中:插件 - > Python脚本 - >配置,并将初始化设置为ATSTARTUP。 When Notepad++ starts, the
startup.py
script will run. 当Notepad ++启动时,将运行
startup.py
脚本。
Find startup.py
and edit it. 找到
startup.py
并进行编辑。 On my PC its path is c:\\Program Files\\Notepad++\\plugins\\PythonScript\\scripts\\startup.py
, add the following code to startup.py
. 在我的PC上它的路径是
c:\\Program Files\\Notepad++\\plugins\\PythonScript\\scripts\\startup.py
,将以下代码添加到startup.py
。
The function buffer_active()
is called every time when you switch tab, and guess_tab()
checks whether the text is using tab indent or not. 每次切换选项卡时都会调用函数
buffer_active()
, guess_tab()
检查文本是否正在使用制表符缩进。 You can show the Python console to debug the code. 您可以显示Python控制台以调试代码。
def guess_tab(text):
count = 0
for line in text.split("\n"):
indents = line[:len(line)-len(line.lstrip())]
if "\t" in indents:
count += 1
if count > 5:
return True
else:
return False
def buffer_active(arg):
editor.setBackSpaceUnIndents(True)
use_tab = guess_tab(editor.getText())
editor.setUseTabs(use_tab)
sys.stderr.write( "setUseTabs %s\n" % use_tab )
notepad.clearCallbacks([NOTIFICATION.BUFFERACTIVATED])
notepad.callback(buffer_active, [NOTIFICATION.BUFFERACTIVATED])
This is only an example, feel free to make guess_tab()
better yourself, maybe use a global dict to cache the result and speedup the callback function. 这只是一个例子,随意使
guess_tab()
更好,也许使用全局dict来缓存结果并加速回调函数。

import re
import time
def indent_guess_tab(text):
for line in text.split("\n"):
pattern = re.compile("^( {4,}|\t)")
match = pattern.match(line)
if (match):
return True if ("\t" in match.group(1)) else False
def indent_auto_detect(arg):
start = time.clock()
# Get text sample
maxLen = 500000
len = editor.getTextLength()
len = len if len < maxLen else maxLen
sample = editor.getTextRange(0, len)
# Indent set
current_use_tab = editor.getUseTabs()
use_tab = indent_guess_tab(sample)
if (use_tab != None and use_tab != current_use_tab):
console.write("Indent use tab switch (%s => %s)\n" % (current_use_tab, use_tab))
editor.setUseTabs(use_tab)
end = time.clock()
console.write("Indentation detection took %s ms\n" % (round((end-start)*1000, 3)))
notepad.clearCallbacks([NOTIFICATION.BUFFERACTIVATED, NOTIFICATION.READY])
notepad.callback(indent_auto_detect, [NOTIFICATION.BUFFERACTIVATED])
notepad.callback(indent_auto_detect, [NOTIFICATION.READY])
console.write("Automatic indentation detection started\n")
indent_auto_detect(None)
Nope! 不!
You can always just change them (to tabs , of course) to suit your needs with Replace All ( 您可以随时更改它们(当然是更改标签 )以满足您的需求(全部替换)
