我正在尝试为 nix 语言添加 vim 语法突出显示,并且一直在尝试使用 this github repo 来做到这一点。
在那个 repo 中,我找到了 nix.vim
file .我试过把它放在 ~/.vim
根据存储库的“手动安装”说明,但这无法使颜色出现。
自那次尝试以来,我一直试图通过更改我的 /etc/nixos/configuration.nix
来获得语法着色。文件,并且一直试图从 this documentation 中理解。 .因此,我在我的配置文件中添加了 programs.vim
代码块,
programs.vim = {
enable = true;
extraConfig = ''
'';
};
并粘贴了整个
nix.vim
的内容文件放入该 programs.vim.extraConfig
的字符串中部分。因此 block 添加到我的configuration.nix
是:programs.vim = {
enable = true;
extraConfig = ''

这给了我在线
syn match nixStringSpecial /''['$]/ contained
上的问题因为双引号 ''
过早结束 nix 字符串。在这一点上,我不确定是否应该尝试解决这里的字符串定界问题,或者尝试其他方法。这是否正朝着让 vim 突出显示在我的 nixos 机器上工作的 nix 语言的正确轨道上?
最佳答案
正如上面的评论中已经提到的,让它工作的解决方案如下:nix.vim
语法文件需要放在~/.vim/syntax
目录和以下行需要添加到您的 .vimrc
:au BufRead,BufNewFile *.nix set filetype=nix
此行确保 vim 识别文件类型 .nix
文件并激活正确的语法突出显示。
