tidy

Clean up and pretty print HTML, XHTML and XML files. Note: tidy cannot preserve original indentation. More information: https://api.html-tidy.org/tidy/tidylib_api_5.2.0/tidy_cmd.html.

• Pretty print an HTML file:

tidy {{path/to/file.html}}

• Enable [i]ndentation, [w]rapping lines in 100, saving to output.html:

tidy --indent y --wrap 100 -output {{path/to/output.html}} {{path/to/file.html}}

• Modify an HTML file in-place using a configuration file:

tidy -config {{path/to/configuration}} -modify {{path/to/file.html}}
