Vim Scripting

Variables

• Vim built in variables use the following prefixes
  • $ for environment variables
  • & for options
  • @ for registers

Functions

• See the predefined functions by invoking :help function-list
• User-defined functions have to start with an upper case character.

Feature Checking

• To check if the currently installed Vim has a particular feature enabled/compiled in then we can use the has(<feature-name>) function.
• Use :help feature-list to see the list of available features.

If-Else
