previewtag is a Vim plugin that allows you to preview the definition and switch it to a new window.
The script opens the definition of functions and variables in preview window on demand and provides the operations to close the preview window, delete the buffer in preview window and switch the buffer in preview window in a new window. Quite simple, but useful.
The script provides four commands:
Pshow: open the definition of current word in preview window
Pdelete: delete the buffer showing in preview window
PshowORdelete: if the cursor is in preview window, delete the current buffer (like Pdelete); Otherwise open the definition of current word in preview window
Pswitch: if the preview window is open, close it and open the buffer in a new window
Vim also provides a "pclose" command to close the preview window, without deleting the buffer.
Developer comments
If you want to open the tag preview immediately when you put cursor on a word, please uncomment the last line of the script. However, I found automatically preview is kind of boresome, so I do not provide a switch of auto-preview in the script.
