是否可以在 Vim 中重新加载编译器插件？

Question

I am creating a small compiler plugin in Vim and I'm finding very slow to debug it. It seems like there are ways to debug the errorformat but some times I just want to force Vim to reload my compiler plugin that I created in ~/.vim/after/compiler/

It doesn't look like I can just source the file as it fails because of CompilerSet . Is there any other way of reloading a compiler plugin?

Answer 1

Simply running :compiler {name} should reload your full compiler script.

See :help:compiler with the details of how a compiler plug-in is loaded.

An alternative is to source the compiler plug-in file directly. In order to handle the :CompilerSet command, you can either define the user command yourself before you run the plug-in file, or use a snippet in your plug-in file itself to define it if not defined already.

Many of the compiler plug-ins shipped with Vim include this snippet at the top:

if exists(":CompilerSet") != 2      " older Vim always used :setlocal
  command -nargs=* CompilerSet setlocal <args>
endif

So apparently that's all you need...

But using :compiler {name} each time to fully source it should be a better approach, assuming that's a possibility to you.

Answer 2

(Tangentially) I find tpope's scriptease plugin to have many benefits when working on a vim plugin (and also when writing answers to vim questions where I have to dig deep into runtime files).

Highlights:

• :PP is both a pretty-printer and a repl
• :Runtime helps reload files
• :Breakadd is much smarter
• :Vedit and cousins open up files on the runtime path
