ansifilter, tool to convert color codes in log file into color html

ansifilter is an open source tool which can convert ssh session logs (with putty) with ansi escape codes into html with colors.

First, putty should be configured with “all session output”, see figure below. Next, the log file should contain some ANSI escape codes. For creating colors with the help of awk script, please see another blog.

The log file

The text below is how the log file looks like. It contains the printout from the mount command.

Minor issue: background color

I haven’t found a good way to get black background when using the GUI tool. With the command line tool, it is possible to use stylesheet to set the background color.

When using GUI

After saving the output into html, then one can modify the HTML <body> tag to get the background color, please see below:

<body style=”color:white;background-color:black”>

When using CLI

First create a stylesheet.css file with the following content

body {
background-color: #050505;
color: #808080;
}

Then execute the ansifilter command. If the log file is “mount.log” and output is mount.html, then command looks like this:

ansifilter.exe -H -i mount.log -o mount.html -r stylesheet.css

Please note that, the html output is now referring to that stylesheet as it add the following line to the html:

<link rel=”stylesheet” type=”text/css” href=”stylesheet.css”>

HTML output

And the result is here below. Please compare it to the screenshot in the other blog.
