view runtime/tools/blink.c @ 4726:3849c811cc0b v7.3.1110

updated for version 7.3.1110 Problem: New regexp matching: Using \@= and the like can be slow. Solution: Decide whether to first try matching the zero-wdith part or what follows, whatever is more likely to fail.

/*
 * An extremely simple program to make the cursor blink in an xterm.
 * This is useful when the cursor is hard to spot in a highlighted file.
 * Start in the background: "blink&"  Stop by killing it.
