neovim compiler

Last modification:

A vertical split inside the neovim ui which shows the result of a compilation (aka. preconfigured shell command). neovim-compiler-view-rust.png view of the 'plugin'

Why this "plugin"?

  • fast compiles with both compiler output and source in view.
  • neovim based view splitting without dependencies
  • just some fun

Special cases

Because I code in Java and Java imao no clearly defined (aka. dev-group dependent) workflow for libs has, I choose to trigger the execution of `./java.meta.sh` just a file which the executable shell command to compile the project.
