加载时出现慢性 ripgrep/vim 插件错误:“-complete 使用而没有 -nargs"? [英] Chronic ripgrep / vim Plugin Error on Load: "-complete Used Without -nargs"?

问题描述

我最近将 ripgrep 添加到了我的 vim 插件 列表中，并且在安装后立即开始在加载 vim 时收到此错误消息:

I recently added ripgrep to my list of vim plugins and, immediately after installation, I began receiving this error message whenever I loaded up vim:

Error detected while processing /Users/my_macbook/.vim/plugged/vim-ripgrep/plugin/vim-ripgrep.vim:

line  149: E1208: -complete used without -nargs
Press ENTER or type command to continue

打开有问题的文件并查看第 148-149 行发现:

Opening the offending file and reviewing lines 148-149 reveals:

148 command! -nargs=* -complete=file Rg :call s:Rg(<q-args>)
149 command! -complete=file RgRoot :call s:RgShowRoot()

我很好&在这里真的超出了我的深度，特别是考虑到这个错误是通过简单地安装插件产生的；我对底层文件 (vim-ripgrep.vim) 进行了 0 次更改.

I am well & truly out of my depth here, especially considering that this error was generated by simply installing the plugin; I've made 0 changes to the underlying file (vim-ripgrep.vim).

有没有人在安装 ripgrep 后遇到过类似的长期错误，如果有，您是如何解决的?

推荐答案

恭喜，您在 FOSS 程序中发现了一个错误.下一步是通过他们的问题跟踪器通知维护者，或者，如果您知道如何修复它，则提交补丁.

Congratulations, you have found a bug in a FOSS program. Next step is to either notify the maintainer via their issue tracker or, if you know how to fix it, submit a patch.

举个例子，作者分配了一个完成方法，-complete=file，但是像:RgRoot这样的自定义命令默认不接受参数，所以命令使没有意义原样:如果你不能传递参数，你就不能完成参数.

Case in point, the author assigns a completion method, -complete=file, but custom commands like :RgRoot don't accept arguments by default so the command makes no sense as-is: you can't complete arguments if you can't pass arguments.

它只需要一个 -nargs=*，就像它楼上的邻居，:Rg，才能正常工作，错误信息也很清楚:

It only needs a -nargs=*, like its upstairs neighbour, :Rg, to work properly and the error message is pretty clear about it:

line  149: E1208: -complete used without -nargs

参见:help -complete、:help -nargs，以及更一般的:help user-commands.

See :help -complete, :help -nargs, and more generally, :help user-commands.
