NAME

App::highlight - simple grep-like highlighter app

SYNOPSIS

highlight is similar to grep, except that instead of removing non-matched lines it simply highlights words or lines which are matched.

% cat words.txt
foo
bar
baz
qux
quux
corge

% cat words.txt | grep ba
bar
baz

% cat words.txt | highlight ba
foo
>>ba<<r
>>ba<<z
qux
quux
corge

If you give multiple match parameters highlight will highlight each of them in a different color.

% cat words.txt | highlight ba qu
foo
>>ba<<r
>>ba<<z
[[qu]]x
[[qu]]ux
corge

Note that brackets are not used to highlight the words, Term::ANSIColor terminal highlighting is used.

OPTIONS

no-escape [n]

This allows you to specify a regular expression instead of a simple string.

% cat words.txt | highlight --no-escape '[abcde]+'
foo
>>ba<<r
>>ba<<z
qux
quux
>>c<<org>>e<<

full-line [l]

This makes highlight always highlight full lines of input, even when the full line is not matched.

% cat words.txt | highlight --full-line u
foo
bar
baz
>>qux<<
>>quux<<
corge

Note this is similar to '--no-escape "^.*match.*$"' but probably much more efficient.

one-color [o]

Rather than cycling through multiple colors, this makes highlight always use the same color for all highlights.

% cat words.txt | highlight --one-color ba qu
foo
>>ba<<r
>>ba<<z
>>qu<<x
>>qu<<ux
corge
