Execute current line in bash from vim

阅读更多关于 Execute current line in bash from vim

问题 This question is similar to Vim: execute current file? but instead of executing the current file I want to execute only the current line. Is this possible? Update: Ideally, I am looking for solutions which can have side effects in the outer shell. For example, suppose I have the following line: alias foo=bar After running the command in vim, if I start a shell with :sh , the alias foo is available, but if I quit vim using :q , then the alias is no longer available. 回答1: Sure thing, you can

Vim: Delete buffer without losing the split window

阅读更多关于 Vim: Delete buffer without losing the split window

问题 When a buffer gets deleted (the "bd[elete]" command), it not only deletes the buffer but also removes the split window that buffer was in. Is there a way to delete/unload a buffer and keep the window split? 回答1: I really like bufkill.vim there is a github repo as well 回答2: bp|bd # will do it. Details: bp ("buffer previous") moves us to a different buffer in the current window ( bn would work, too), then bd # ("buffer delete" "alternate file") deletes the buffer we just moved away from.

Exact string match in vim? (Like 'regex-off' mode in less.)

阅读更多关于 Exact string match in vim? (Like 'regex-off' mode in less.)

问题 In vim , I often want to search on a string with finicky characters which need escaping. Is there a way I can turn off the meaning of all special characters, kind of like regex-off mode in less, or fgrep ? I am dealing with particularly hairy strings; here's an example: ((N/N)/(N/N))/N Not having to escape any characters to do a search in vim would be a major timesaver. \V in Vim helps with some metacharacters, but critically not / or \. Thanks all! In the end, I added this to my .vimrc:

Vim “annoyance” with keyboard layouts

阅读更多关于 Vim “annoyance” with keyboard layouts

问题 Here's the thing. I have two keyboard layouts, HR (Croatian, my native language) and EN (English). Well, actually I have some more but they're not important at the moment. When working with Vim I often have to switch to EN—since on HR I don't have neither [ , ] nor { , } nor a lot of other characters—and then back to HR for my own language's characters. This is a pain. Of course, since I'm working without a taskbar this often results in wasted Shift pressing. Is there a way within Vim to

Auto-reload browser when I save changes to html file, in Chrome?

阅读更多关于 Auto-reload browser when I save changes to html file, in Chrome?

问题 I'm editing an HTML file in Vim and I want the browser to refresh whenever the file underneath changes. Is there a plugin for Google Chrome that will listen for changes to the file and auto refresh the page every time I save a change to the file? I know there's XRefresh for Firefox but I could not get XRefresh to run at all. How hard would it be to write a script to do this myself? 回答1: I assume you're not on OSX? Otherwise you could do something like this with applescript: http:/
