Hi all,
I was concerned about Vim's weird indentation of HTML, and Tim Chase
clued me in about Tidy, which does most of what I want but leaves no
blank lines. I want 3 blank lines above each <h1>, and one blank line
above each of <h[[:digit:]]>, <ol>, <ul>, <table>, <p>, <body>, and
<div>.
However, to make <h1> stand out even more, I don't want any blank lines
immediately below an <h1>, even if the line below it is one that would
normally have a blank line above it. Also, I want to be able to run
this filter over and over again on generations of the file without
building up huge numbers of blank lines. The following Awk program does
all this:
#!/usr/bin/gawk -We
BEGIN {suppressnextblank=0}
{printblank = 0}
tolower($0) ~ /^<h1/ {printblank=1
suppressnextblank=3
print "\n"
}
tolower($0) ~ /^<h[[:digit:]]/ {printblank=1}
tolower($0) ~ /^<ul/ {printblank=1}
tolower($0) ~ /^<ol/ {printblank=1}
tolower($0) ~ /^<table/ {printblank=1}
tolower($0) ~ /^<p/ {printblank=1}
tolower($0) ~ /^<body/ {printblank=1}
tolower($0) ~ /^<div/ {printblank=1}
printblank == 1 {suppressnextblank--}
printblank == 1 && suppressnextblank != 1 {print ""}
$0 !~ /^\s*$/ {print $0}
Thanks for everyone's help,
