vim-latex与vimtex如何选择

发表于 2024-01-16 更新于 2025-03-26

作为一个理科生，终生都离不开数学公式。而LaTeX绝对是处理数学公式的王者，在编辑LaTeX中的众多工具中，使用vim或neovim配合编辑LaTeX的插件又是王者中的王者。在众多的插件中，vim-latex和vimtex是网络上提到最多的，也是使用者最多的插件，但是这两者该如何选择呢？经过本人的实践，最终选择了vim-latex.

选择依据分析

众多网络文章都提到了插件vimtex, 按其官方介绍：VimTeX is a modern Vim and Neovim filetype and syntax plugin for LaTeX files. , 或许就是这个modern让许多人选择了它。诚然vimtex是一个优秀的插件，我们来看一下它提供的功能（引用其README.md）：

vimtex提供的功能

而插件vim-latex（又称latex-suite）, 按vimtex的README.md

vim-latex vs vimtex

The main difference between VimTeX and LaTeX-Suite (aka vim-latex) is probably that VimTeX does not try to implement a full fledged IDE for LaTeX inside Vim. E.g.:

VimTeX does not provide a full snippet feature, because this is better handled by UltiSnips or neosnippet or similar snippet engines.
VimTeX builds upon Vim principles: It provides text objects for environments, inline math, it provides motions for sections and paragraphs
VimTeX uses latexmk, latexrun, tectonic or arara for compilation with a callback feature to get instant feedback on compilation errors
VimTeX is very modular: if you don't like a feature, you can turn it off.

这两个插件有相同的部分，比如说输入希腊字母，vim-latex在任何模式下都可以输出对应的希腊字母命令，而vimtex在数学模式中才输出希腊字母，相较而言vimtex更加保险一些，但是对于一个熟悉LaTeX的人来讲，这个事情都是知道的，影响不大，只能说vimtex更加细致一点。而vim-latex提供了完整的LaTeX的输入语法，同时提供了<++>标记方法，可以使用Ctrl+j快速的移动光标，这点是vimtex所无法比拟的。按vimtex的说法，vimtex把补全的任务交给了其他插件，但是就专业性和速度上讲，vim-latex绝对领先。

vimtex提供的较好的特性是光标在各环境中移动，这点是vim-latex不具备的功能。但是vim或neovim的特性，使用搜索功能或数字键加hjkl方式移动光标，好像vimtex也没有占据足够的优势。

vimtex方便的更改环境功能，例如cse可以方便的更换为新的环境，但是vim-latex也可以使用<S-F5>快捷键快速更换环境，再则考虑到编写环境前作者肯定是规划好的环境，所以更改环境是一个低概率事件。此处注意，Neovim中同时按下组键<S+F5>(也就是Shift+F5)返回的是F17,并不能获得vim-latex所需的组合键<S-F5>!! 具体请参考keycode in terminal for vim&neovim, 于是做出修改：

~/.config/nvim/init.vim

map <F17> <S-F5>
imap <F17> <S-F5>
map <F19> <S-F7>
imap <F19> <S-F7>

修改完毕，在neovim中可以正常使用环境或命令的替换。很多人选择vimtex的一个重要原因是其可以配置增量编译，实现时时查看结果，但是LaTeX的精神本身就是所想即所得！对于一个熟悉LaTeX的人来讲随时关注结果并不是必须的，除非公式比较复杂，而这只需要编译一下看看结果即可。时时编译的代价就是电脑消耗更多的资源，对于我的笔记本来说，风扇一直转发出的噪音会干扰我的写作思维。对于一个初入LaTeX的人，这或许是一个较好的选择，但是对于一个足够熟悉LaTeX的人来讲，所见即所得不是必须的，也是符合Linux思维。

综上所述，vim-latex和vimtex都是优秀的LaTeX插件，但是前者提供了完备的功能，后者的优势功能是一些低频率使用的功能，综合平衡的话还是选择vim-latex更好一些。由于二者并不冲突，所以可以同时配置二个插件，获取各自的功能这是一个比较折中的方案，但是不太符合Linux纯净化的哲学思想，所以我还是选择了前者，在没有足够的理由前应该不会同时安装二者。

作为可用的配置，下面将二者的配置文件列出，方便大家参考：
