Small clink script to automatically expand ~ to %HOME% in any command the user executes via Windows' CMD shell.

Simply place HomeClink.lua in any of the directories listed under 'scripts' when you run clink info, then start a new CMD session.

Type any command and execute it as usual, any unescaped ~ will invisibly expand to %HOME%.

Any intentional tildes that are NOT intended be expanded should be escaped with a preceding |.

For example, echo |~ will output ~, because tilde was escaped, but echo ~ will output C:\Users\USER (assuming your primary drive is C:).

In addition to |-escaped tildes, there are other cases when a tilde will not be expanded. This script relies on Clink's builtin rl.expandtilde function for the actual tilde expansion, and this has its own quirks, such as:

• Not expanding tildes in quoted paths.
  • E.g. The tilde in cd ~/blah blah will expand, but cd "~/blah blah" won't.
• Only expanding each tilde at the start of each word/segment of a command.
  • E.g. cd ~\~ becomes cd C:\Users\USER\~, rather than cd C:\Users\USER\C:\Users\USER\
• Not expanding any tilde thought to be directly part of a filename, for example if followed by an extension.
  • E.g. cat ~.txt will always stay cat ~.txt, and will never expand to cat C:\Users\USER\.txt.
  • However, cat ~\~.txt will become cat C:\Users\USER\~.txt.
