Can emacs re-indent a big blob of HTML for me?

Answer 1

The easiest way to do it is via command line.

• Make sure you have tidy installed
• type tidy -i -m <>

Note that -m option replaces the newly tidied file with the old one. If you don't want that, you can type tidy -i -o <> <>

The -i is for indentation. Alternatively, you can create a .tidyrc file that has settings such as

indent: auto
indent-spaces: 2
wrap: 72
markup: yes
output-xml: no
input-xml: no
show-warnings: yes
numeric-entities: yes
quote-marks: yes
quote-nbsp: yes
quote-ampersand: no
break-before-br: no
uppercase-tags: no
uppercase-attributes: no

This way all you have to do is type tidy -o <> <>.

For more just type man tidy on the command line.
