我发现
vimdiff
实用程序只是 vim 的软链接。两者都位于我的 Suse11 框中的 /usr/bin/
下。 vimdfiff
是 vim 的软链接。有趣的是,vimdiff file1 file2
实际上相当于vim -d file1 file2
,所以在
感觉, -d
选项会自动嵌入到软链接中,所以我的问题很简单
怎么办?
Vim 在其
main()
函数中使用 argv[0]
来区分其可执行文件名称 vim
或 vimdiff
等
链接到 vim main.c,执行此检查以区分
rvim
、rview
、gvim
、gview
、vimdiff
、gvimdiff
、ex
、exim
。
/*
* Check for: [r][e][g][vi|vim|view][diff][ex[im]]
* If the next character is "e" we run in Easy mode.
* If the next character is "g" we run the GUI version.
* If the next characters are "view" we start in readonly mode.
* If the next characters are "diff" or "vimdiff" we start in diff mode.
* If the next characters are "ex" we start in Ex mode. If it's followed
* by "im" use improved Ex mode.
