Master Elbarap was an elder, great and venerated teacher our village.

Before he departed from us, he sat with two of his students who were struggling with a difficult maths equation.

He gave them lessons and keys and analogies to use, and their understanding grew until they could understand the formulas themselves, enough to even teach it to others.

The two understood, and in their delight they thanked the elder with great glee, for now the dark clouds of confusion were gone.

The elder gave both of them a hug, smiling at them, and then swiftly fled out from the room.

# SSH Agent
# Note: ~/.ssh/environment should not be used, as it
# already has a different purpose in SSH.

# Note: Don't bother checking SSH_AGENT_PID. It's not used
# by SSH itself, and it might even be incorrect

vim regular expressions for perl regex fans


Vim regular expressions are powerful, but they pre-date Perl.

This can be frustrating since the Perl-flavored-regex syntax has expanded beyond into other programming languages and contexts, becoming a de-facto standard.

This guide is a quick cheatsheet and tipsheet for using regular expressions in Vim for those who may be more familiar with Perl.

Quick examples for vimmers who like Perl regex
