Grab a line's whitespace/indention with Python

阅读更多关于 Grab a line's whitespace/indention with Python

Basically, if I have a line of text which starts with indention, what's the best way to grab that indention and put it into a variable in Python? For example, if the line is: \t\tthis line has two tabs of indention Then it would return '\t\t'. Or, if the line was: this line has four spaces of indention Then it would return four spaces. So I guess you could say that I just need to strip everything from a string from first non-whitespace character to the end. Thoughts? import re s = "\t\tthis line has two tabs of indention" re.match(r"\s*", s).group() // "\t\t" s = " this line has four spaces of

Copy-paste into Python interactive interpreter and indentation

阅读更多关于 Copy-paste into Python interactive interpreter and indentation

This piece of code, test.py: if 1: print "foo" print "bar" can be succesfully executed with execfile("test.py") or python test.py , but when one tries to copy-paste it into python interpreter: File "<stdin>", line 3 print "bar" ^ SyntaxError: invalid syntax Why is it so? Can interpreter by configured in such a way that it would read copy-pasted text succesfully? I guess that may affect typing in the interpreter, but that's ok for me. rplnt Indentation is probably lost or broken. Have a look at IPython -- it's enhanced python interpreter with many convenient features. One of them is a magic

When the cursor is placed at the end of a line containing nothing but withspace characters, vim will, when i press enter, remove that whitespace.

阅读更多关于 How to preserve whitespace indentation of text enclosed in HTML tags excluding the current indentation level of the tag in the document?

I'm trying to display my code on a website but I'm having problems preserving the whitespace indentation correctly. For instance given the following snippet: <html> <body> Here is my code: <pre> def some_funtion return 'Hello, World!' end </pre> <body> </html> This is displayed in the browser as: Here is my code: def some_funtion return 'Hello, World!' end When I would like it displayed as: Here is my code: def some_funtion return 'Hello, World!' end The difference is that that current indentation level of the HTML pre tag is being added to the indentation of the code. I'm using nanoc as a

Indenting entire file in Vim without leaving current cursor location

阅读更多关于 Indenting entire file in Vim without leaving current cursor location

问题 I already know that gg=G can indent the entire file on Vim. But this will make me go to the beginning of the file after indent. How can I indent the entire file and maintain the cursor at the same position? 回答1: See :h '' This will get you back to the first char on the line you start on: gg=G'' and this will get you back to the starting line and the starting column: gg=G`` I assume the second version, with the backtick, is the one you want. In practice I usually just use the double apostrophe

How do I autoindent in Netbeans?

阅读更多关于 How do I autoindent in Netbeans?

In eclipse you can click Ctrl + I at any line, and it'll automatically indent the line or group of lines according to the indentation scheme you chose in the settings. I'm really missing this feature in Netbeans. Is there any equivalent feature? I'm aware of Alt + Shift + F but it's not good enough. I want to indent a group of lines, and not all the file. varad Open Tools -> Options -> Keymap , then look for the action called "Re-indent current line or selection" and set whatever shortcut you want. Pressing Alt + Shift + F indents your selection. If nothing's selected, it indents the whole
