语法高亮的Fortran 77评论在vim中不工作 [英] Syntax highlighting of Fortran 77 comments not working in vim

问题描述

我有一个代码写在Fortran 77，我用vim读它。代码是这样写的，注释是在 c 开始的行上，这是Fortran 77的标准。然而，vim不能识别它们，因此使用着色语法代码很难读！我如何克服这个？

我看到有一个 post有相同的问题。我已经阅读了答案，并尝试了不同的解决方案，建议：

1. 添加 let fortran_have_tabs = 1 $

   c $ c> syn match fortranComment excludenl^ [！c *]。* $contains = @ fortranCommentGroup，@ spell
   syn match fortranComment excludenl！。* $contains = @ fortranCommentGroup，@ spell
   

   至.vimrc

但他们不适合我。有人知道为什么吗？我在某个地方犯了错误？

解决方案

这对我的.vimrc有效：

  let fortran_have_tabs = 1 
 if has（'syntax'）&& （& t_Co> 2）
语法启用
 endif 
  

部分最有可能是语法enable 部分。您可能还需要此：

  
上的文件类型 

还要尝试输入：help ft-fortran-syntax 并阅读（或参见这里： http://vimdoc.sourceforge.net/htmldoc/syntax.html#ft-fortran-syntax ）。我从中删除了，我需要创建文件〜/ .vim / ftplugin / fortran.vim ，并把它在其中：

  let s：extfname = expand（％：e）
如果s：extfname ==？ f90
 let fortran_free_source = 1 
 unlet！ fortran_fixed_source 
 else 
 let fortran_fixed_source = 1 
 unlet！ fortran_free_source 
 endif 
  

并将其放在.vimrc中：

  filetype插入缩进
  

这对我来说，让我可以查看和编辑自由形式和固定形式没有问题。

I have a code written in Fortran 77 and I read it with vim. The code is written such that the comments are on lines starting with c, as is standard in Fortran 77. However, vim does not recognize them and therefore use a coloring syntax that makes the code very difficult to read! How can I overcome this?

I've seen that there is a post with the same problem. I have read the answers and tried the different solutions that have been suggested:

1. add let fortran_have_tabs=1 to .vimrc

2. add

   syn match fortranComment excludenl "^[!c*].*$" contains=@fortranCommentGroup,@spell
   syn match fortranComment excludenl "!.*$" contains=@fortranCommentGroup,@spell
   

   to .vimrc

but they do not work for me. Does someone know why? Have I made a mistake somewhere? Otherwise, does anyone have a different suggestion?

解决方案

This is what works for me in my .vimrc:

let fortran_have_tabs=1
if has('syntax') && (&t_Co > 2)
    syntax enable
endif

The important part is most likely the syntax enable part. You may also need this:

filetype on

Also try typing in :help ft-fortran-syntax and reading that (or see here: http://vimdoc.sourceforge.net/htmldoc/syntax.html#ft-fortran-syntax). What I took away from that was that I needed to create the file ~/.vim/ftplugin/fortran.vim and put this in it:

let s:extfname = expand("%:e")
if s:extfname ==? "f90"
  let fortran_free_source=1
  unlet! fortran_fixed_source
else
  let fortran_fixed_source=1
  unlet! fortran_free_source
endif

And also put this in your .vimrc:

filetype plugin indent on

That does the trick for me so that I can view and edit free-form and fixed-form with no problem.
