问题 I use vim(in console) 7.1 for rails developments on OSX or Ubuntu. Here's what I repeatedly do when I edit files of rails. cd RAILS_ROOT vim :Rproject .project Is there a way that the last part is automatically done? For example, I just type 'vim -some_arg' and it automatically triggers ":Rproject .project"? If that's not possible, can I alias "Rproject .project" to "Rp"? I am familiar with vim editing but not vim script. Help me please. Sam 回答1: there is probably a better way to do this, but

How to efficiently escape meta-characters in vim search

阅读更多关于 How to efficiently escape meta-characters in vim search

问题 Perl provides quotemeta function, as well as the possibility to surround strings using the \Qlots-of-meta-characters\E construct, to make sure that all the characters between \Q and \E are interpreted as literals. Very often I search strings full of meta characters in Vim. It's counterproductive to escape every special character individually. Is there anything like /\Qstring-to-search\E in Vim, which would make life easier? 回答1: You can use /\Vstring-to-search . There are two caveats: \ is

Vim automatic scroll buffer

阅读更多关于 Vim automatic scroll buffer

问题 I'm trying to do something very simple: I have two buffers in Vim, one with source code (B1), another one with a text file a.txt (B2). The source code in B1 is run with a custom shortcut in Vim, filling a.txt with text. I want Vim to automatically scroll B2 every time it updates, even if my cursor is in B1. So, I just want that the buffer B2 to behave the way tail -f does. Doing this with ConqueTerm is not an option, since buffer B2 can be a preview buffer from other plugin. 回答1: In general,

1.安装git： sudo yum install git 2.安装mysql客户端(如果数据库在本机需要安装mysql服务端) wget https://dev.mysql.com/get/mysql-community-client-5.7.25-1.el7.x86_64.rpm rpm -Uvh mysql-community-client-5.7.25-1.el7.x86_64.rpm 如果此处报错则在后面加上--force --nodeps(由于yum安装了旧版本的GPG keys造成的) 3.安装python3 sudo mkdir /usr/local/python3 # 创建安装目录 wget --no-check-certificate https://www.python.org/ftp/python/3.6.4/Python-3.6.4.tgz #下载Python源文件 # 注意：wget获取https的时候要加上：--no-check-certifica tar -xzvf Python-3.6.4.tgz # 解压缩包 cd Python-3.6.4 # 进入解压目录 sudo ./configure --prefix=/usr/local/python3 # 指定创建的目录 sudo make sudo make install # 编译安装

Default GNU Linker Script name so VIM does Syntax Highlighting

阅读更多关于 Default GNU Linker Script name so VIM does Syntax Highlighting

问题 What is the usual suffix for a linker script so that VIM will use syntax-highlighting on it? 回答1: It seems to be .ld , only from what I see Vim doesn't come (at least mine doesn't, 7.3.) with the syntax files for it. Try the ones offered for download here. 来源： https://stackoverflow.com/questions/9612818/default-gnu-linker-script-name-so-vim-does-syntax-highlighting

问题 I've set tab to equal 2 spaces in my vimrc. This works when I edit java files, but for some reason when I edit python files, tab is set to 4 spaces instead.

Vim grep causes characters to temporarily disappear

阅读更多关于 Vim grep causes characters to temporarily disappear

问题 I am working through Learn Vimscript the Hard Way" by Steve Losh. In chapter 32 we build a grep command that puts results in the quickfix window. It looks like this: :nnoremap <leader>g :silent :exe "grep! -R " . shellescape(expand("<cWORD>")) . " ."<cr>:copen<cr> It basically works, but when I run it, it will cause characters to become (temporarily) invisible. If I close and re-open the file, the characters come back. Also, if I search for the invisible characters, they appear. For example,
