From 946c53ed7ff53f38792ac35e5da21de3e0a48ef2 Mon Sep 17 00:00:00 2001 From: "Andrew M. Kuchling" Date: Thu, 24 Apr 2003 17:13:18 +0000 Subject: Run these demo scripts through reindent.py to give them 4-space indents. I've verified that their output is unchanged. --- Demo/comparisons/regextest.py | 46 ++++++++++---------- Demo/comparisons/sortingtest.py | 48 ++++++++++----------- Demo/comparisons/systemtest.py | 96 ++++++++++++++++++++--------------------- 3 files changed, 95 insertions(+), 95 deletions(-) (limited to 'Demo/comparisons') diff --git a/Demo/comparisons/regextest.py b/Demo/comparisons/regextest.py index 97564b7939..e4e18d6d58 100755 --- a/Demo/comparisons/regextest.py +++ b/Demo/comparisons/regextest.py @@ -1,13 +1,13 @@ #! /usr/bin/env python # 1) Regular Expressions Test -# -# Read a file of (extended per egrep) regular expressions (one per line), +# +# Read a file of (extended per egrep) regular expressions (one per line), # and apply those to all files whose names are listed on the command line. # Basically, an 'egrep -f' simulator.
