NAME
aha — Convert ANSI escape sequences to HTML
SYNOPSIS
aha [-bhlnprsvwx] [-c file] [-f file] [-i X] [-L LANG] [-t TITLE] [-y STYLE]
DESCRIPTION
aha reads ECMA-48 SGR-colored text from the standard input, converts it to colored HTML and writes it to the standard output. The options are as follows:
-b, --black
Style HTML output to use a black background with white text.
-c file, --css file
Adds the given css file to the output. In fact just adds <link rel="stylesheet" href=" file " /> to the header.
-f file
Read from file instead of from the standard input.
-h, --help, -?
Print help for aha to the standard output.
-i X, --iso X
Use the ISO-8859-X character encoding instead of UTF-8 for the output, where X is a number from 1-16.
-l, --line-fix
Use a fix for inputs using control sequences to change the cursor position. This is a hot fix, thus it may not work with every program.
-L LANG, --lang LANG
Uses the ISO-639-1 code LANG for the language.
-n, --no-header
Do not enclose HTML output in <html>, <head> and <body> tags.
-p, --pink
Style HTML output to use a pink background.
-r, --ignore-cr
Ignore all carriage-returns (ASCII sign 13, \r) which may lead to double new lines in html.
-s, --stylesheet
Use a stylesheet instead of inline styles.
-t TITLE, --title TITLE
Set the HTML document title to TITLE instead of "stdin" or the filename.
-v, --version
Print version number of aha to the standard output and exit.
-w, --word-wrap
Wrap long lines in the html output. Works with CSS3 supporting browsers and many older ones.
-x, --no-xml
Don’t use doctype xml but html (may useful for old browsers like IE)
-y STYLE, --style STYLE
Sets the style used in the <body> element to STYLE after styles set by other parameters.
EXAMPLES
Create an HTML file with a black background, a custom title and a larger font-size using aha’s help:
$ aha -h | aha -b -t ’the awesome aha help’ -y ’font-size:1.875em’ > aha-help.html
Create an HTML file with a white background using the output of diff(1):
$ diff -u --color=always oldfile.c newfile.c | aha > diff.html
Create an HTML file with a black background from the output of htop(1). You have to use option -l due the other new-line-commands htop uses:
$ echo q | htop | aha -b -l > htop.html
Create an HTML file from the output of this man page. man(1) uses bold and underline formatting from nroff(1), which ul(1) converts to SGR:
$ MAN_KEEP_FORMATTING=1 COLUMNS=80 man aha | ul | aha > man-aha.html

BUGS
Blinking text using the HTML tag <blink> and the css property text-decoration:blink have been deprecated on modern browsers, thus requiring the use of option -s and redefining the .blink css class.
