Key bindings to send lines of test code with tmux+vim?

阅读更多关于 Key bindings to send lines of test code with tmux+vim?

问题 I am trying to create an ide-like setup with tmux + vim . I've seen a lot written about this on the internet, but I've been unable to figure out how to do one critical thing: execute test lines of code. For example, you may create a tmux session with a vim pane for writing code and a python pane for executing tests, like so: # Create a new Tmux session. session="ide" tmux start-server tmux new-session -d -s $session -n ide # Split the pane horizontally and launch vim. tmux selectp -t 1 tmux

vim/neovim callback on terminal command completion

阅读更多关于 vim/neovim callback on terminal command completion

问题 So now both vim and neovim support terminal emulators inside them (with the terminal command). (I use neovim.) I often open a terminal inside vim and run some long running build/test command in it, I then close its window in order to save space for coding. I then have to check back on that terminal periodically to see if the command it ran has completed. Is there a way vim can listen to terminal command completion (through interprocess communication or some other way) ? That way I can

Vim overwrites filename when writing

阅读更多关于 Vim overwrites filename when writing

问题 Let's say I have a file called FooBar.java. When I open the file in a powershell window with > vim foobar.java and write the file after editing it, the file gets renamed FooBar.java -> foobar.java.

This is undesired behaviour for me, and I did not have this problem earlier, before I did a clean

How to efficiently copy code from editor to search field in VS Code using vscodevim?

阅读更多关于 How to efficiently copy code from editor to search field in VS Code using vscodevim?

问题 This is currently how I copy code from an editor to a search field in VS code using vscodevim. Select text in editor somehow Right click to open up the contextual menu (since pressing Ctrl+C does not seem to work on Ubuntu, even when in input mode, and 'p' does not work in the search field) and click copy Press Ctrl+Shift+F to open the search field Press Ctrl+V I'm pretty sure this is not how copying from an editor to search field is intended to work.
