背景(feihua)
重新安装了gvim7.4后(发现gvim7.3有显示字符的bug便升级了),忽然想改一下windows下gvim的外观,在看了几个博客,却发现无法设置,于是到官网找到了解决方案,贴在此处。
最初试探的解决方法:
gvim无法自动保存当前手动的设置,比如字体、配色方案。但是修改一下gvim的配置文件,就可以载入我们所希望的设置。
修改vim安装目录下的_vimrc文件,把配色方案设置成黑色背景灰色文字的koehler方案,设置字体大小为14,这样看得不会太辛苦。把下面的代码复制到_vimrc文件的末尾就OK了。

What is vimrc?Edit
The vimrc file contains optional runtime configuration settings to initialize Vim when it starts. On Unix based systems, the file is named .vimrc
, while on Windows systems it is named _vimrc
. :help vimrc
You can customize Vim by putting suitable commands in your vimrc. Here is a very simple example:
" Always wrap long lines: set wrap
Lines that begin with " are comments and are not read by vim.
Search for file vimrc_example.vim
in your Vim files for another example. :help vimrc-intro:help vimrc_example.vim
To customize Vim for editing a specific file, or a specific type of file, you can usemodelines, or auto commands, or filetype plugins. :help auto-setting :help filetype
Location of vimrcEdit
In Vim, your home directory is specified with $HOME
. On Unix systems, this is your ~
directory. On Windows systems, the best way to find the value of $HOME
is from within Vim, as follows. These commands are useful to see what directories your Vim is using:
:version :echo expand(‘~‘) :echo $HOME :echo $VIM :echo $VIMRUNTIME
Note the ‘system vimrc file‘ and ‘user vimrc file‘ paths displayed by the :version
command. The system vimrc file can be created by an administrator to customize Vim for all users. In addition, each user can have his or her own user vimrc.
The output from :version
includes the paths of the system and user vimrc and gvimrc files. For example:
system vimrc file: "$VIM/vimrc" user vimrc file: "$HOME/.vimrc" user exrc file: "$HOME/.exrc" system gvimrc file: "$VIM/gvimrc" user gvimrc file: "$HOME/.gvimrc"
If the gvimrc files exist, they are used to configure Vim when the GUI version (gvim) runs (after settings from vimrc are applied).
Settings for gvim can also be placed in the vimrc file using a has(‘gui_running‘)
check:
if has(‘gui_running‘) set guioptions-=T " no toolbar colorscheme elflord endif
Although this can be useful to avoid the clutter of both a vimrc and gvimrc file, using the gvimrc file has distinct benefits over the "gui_running" check. The most notable being that a gvimrc file is sourced when using the :gui command to change a vim session into a gvim session. Anything that was in the vimrc inside a "gui_running" check will not be applied since the vimrc is only sourced when Vim initially starts.
Per-directory vimrcEdit
Vim can be configured so that, when starting, it reads commands from a vimrc file in the current directory, after reading the primary vimrc. This is configured by adding set exrc
to the primary vimrc file. Setting ‘exrc‘
can be a security problem because it means Vim will execute commands from any vimrc file in the directory where Vim is started.:help ‘exrc‘ For that reason, set the ‘secure‘ option if you use this option, and you may also want to limit setting this option to when Vim is started from known "safe" directory trees:
if getcwd()~=#‘^\(/my/safe/dir1/\|/my/safe/dir2/\)‘ set secure exrc endif
Opening vimrcEdit
If Vim finds your vimrc file during startup, Vim will set the MYVIMRC
environment variable to the full path of the vimrc file. Similarly, if your gvimrc file is found, the MYGVIMRC
variable is set. Therefore, you can easily edit these files from within Vim:
:e $MYVIMRC :e $MYGVIMRC
Using file name completion, you could type :e $M
then press Tab until you see the desired variable. If you only want to see the path, type :echo $M
then press Tab to see the variable, and press Enter.
In gvim, the Edit menu includes "Startup Settings" which will use $MYVIMRC
to edit your vimrc file. If $MYVIMRC
does not exist, "Startup Settings" will create a new file using the "user vimrc file" path shown by the :version
command.
Sourcing vimrcEdit
After you have saved changes to your vimrc file, you can see the results by exiting from Vim, then starting Vim again.
If you are making frequent changes, you might want to "source" (execute) the changed vimrc file without exiting:
:so $MYVIMRC " Alternative that can be used if vimrc is the current file: :so %
Warning You may need to plan your vimrc so re-sourcing does not cause problems. If you define commands, functions, or autocmds, you must make them remove or override the previous version when sourced, or you will get errors (for commands and functions) or duplicates (for autocmds). Here are some examples that will work correctly when re-sourced:
" Use bang (!) to redefine a command or function, if already defined. command! Mycommand echo "Hello!" function! Myfunc() echo "Hello!" endfunction " Put all autocmds in some augroup and use au! to clear the group. augroup vimrc_autocmds au! autocmd BufRead * echo "File read!" augroup END
Recovering from errorsEdit
Some errors in your vimrc may prevent Vim from starting successfully. A reliable way to handle that would be to rename your vimrc file, then edit the renamed file, then give it the correct name. Alternatively, you could start Vim with a command like this (or use "gvim" if that is how you run Vim):
vim -N -u NONE -U NONE
The -N
starts in "not compatible" mode (that is, with extra Vim features). The NONE
argument (must be uppercase) skips initializations and does not read any vimrc file (-u
), and does not read any gvimrc file (-U
).
You could now use the :version
command to show the vimrc path, then enter a command to edit that file.
CommentsEdit
TO DO
- What else is needed to explain what vimrc is, and how to use it, for a beginner?
- Do something with the following text from the original tip (if keep it, need to fix text because it assumes you have used some standard setup for installation, and assumes $VIM and $HOME are some default, and of course is for Windows):
On Windows, when you start Vim normally, it *either* runs the file "C:\Documents and Settings\(user name)\_vimrc" (where "(user name)" is replaced by the actual user name); *or*, if that file doesn‘t exist (it usually doesn‘t, for most users), it runs the file "C:\Program Files\vim\_vimrc". Note that if you have more than one disk your home may be different; do an ":echo $HOME" to know where is your home. You should also see the _viminfo file in that directory.
- Include information for Windows:
- When
$HOME
is not defined, it is created by combining$HOMEDRIVE
and$HOMEPATH
(if defined). - The recommended method to define
$HOMEDRIVE
and$HOMEPATH
is to set the "Home folder ... Local path" on the Profile tab of the User properties in Local Users and Groups (run lusrmgr.msc). - I‘d say that this (the item above) is the recommended method to set your home folder in Windows. The recommendes method to specify where your
_vimrc
is located (if it differs from your home folder) is to set the$HOME
environment variable. (Spiiph 00:16, 29 July 2009 (UTC))
- When
Proposal Omit suggestions like the following that attempt to auto-source vimrc. I suspect that anyone needing to read a tip to do this could get themselves in quite a bit of trouble. IMHO it‘s a lot more sensible to map a key to source a script so you can control when it is sourced. I haven‘t bothered to put such a mapping in the tip so far because the
:so %
info seems more helpful, and entirely adequate. --JohnBeckett 11:56, 23 August 2008 (UTC)
To source changes immediately, add to vimrc:
au BufLeave ~/.vimrc :source ~/.vimrc
- Why not use a BufWritePost instead of BufLeave, so it will source whenever you save?
Getting started tip ... I hit this page because I could not remember the "mkvim" command. I found it elsewhere and thought I‘d throw it in here. If you open vim, change some settings and get things how you like you can use this command
:mkv [file]
to automatically make a vimrc file based on your current settings. The [file] part is optional; vim will use ~/.vimrc by default. If you already have a .vimrc and you attempt this you we will be warned that .vimrc already exists. You can use
mkv!
to overwrite the existing file if you like. However once you do this your original .vimrc file is gone so you may want to back up any existing .vimrc before you try this.
- Using
:mkvimrc
to create.vimrc
isn‘t a terribly good idea, since it saves mappings and abbreviations setup by plugins. It can be useful to copy currently set options to.vimrc
however. (Spiiph 14:51, 27 July 2009 (UTC)) - 参考来源:http://vim.wikia.com/wiki/Open_vimrc_file
