Syntax highlighting randomly disappears during file saving

阅读更多关于 Syntax highlighting randomly disappears during file saving

问题 I'm using vim to edit some python files and recently it occurs sporadically that the syntax highlighting disappears after I save the buffer inside vim. I tried to reset syntax on and set filetype=python but to no avail. I have no clue of what causes this problem at all, so right now I have minimal diagnostic info. But has anyone encountered this before, or where could things break down? 回答1: This is not a solution, but it's hard to write/read in the comments. I meant that I was messing around

问题 Using Vim, I'm trying to pipe text selected in visual mode to a UNIX command and have the output appended to the end of the current file. For example, say we have a SQL command such as: SELECT * FROM mytable; I want to do something like the following: <ESC> V " select text :'<,'>!mysql -uuser -ppass mydb But instead of having the output overwrite the currently selected text, I would like to have the output appended to the end of the file. You probably see where this is going. I'm working on

Some questions on .vimrc and vim configuration

阅读更多关于 Some questions on .vimrc and vim configuration

问题 Generally on a unix system, there is a global vimrc file in the directory /etc or /etc/vim . You can also have a .vimrc file in your home directory that can customize your vi session. Is it possible to have a .vimrc elsewhere in your directory tree so you can use different vi properties in different directories? This would be convenient because the editor properties that help you edit Python most quickly are different from those for editing, say, HTML. This sort of thing does not seem to work

问题 This question already has answers here : Closed 8 years ago . Possible Duplicate: Changing Vim indentation behavior by file type Hello. So, I switch between '2' and '4' spaces for tabs very often. Usually I use 2 spaces for a tab for HTML files and 4 spaces for a tab for programming. Is there anyway to configure VIM, so it will automatically adjust depending on the file extension? Also, how come VIM indents 8 spaces sometimes, like after I enter an open brace? I have it set to 4 spaces.

问题 Sometimes I want to see how many times a certain function is called in a file or a code block. How do you do that? I am using Vim 7.2. I presume you have to use !wc or some such. 回答1: For counting the number of times some pattern occurs, use: :%s/pattern//gn The 'n' flag count the number of occurrences without doing any change to the document. For counting the total number of words, you have several options. If you want to run as an external command: :!wc -w % If you want to run it inside VIM

阅读更多关于 VIM - Sourcing tags from multiple locations in project

问题 Good day, I typically work on relatively small (less than 20,000 lines of code) projects that are all self contained within a single directory, have their own Makefile, and are fairly easy to work with. VIM is my preferred editor, and when I open a project, I typically build the ctags list via a mapping to the F10 key: map <F10> :!ctags -R --c++-kinds=+p --fields=+iaS --extra=+q .<CR> This allows me to jump to the definition of a variable/struct/etc via moving the cursor over the text, and
