pretty-layout in html-mode

pretty-layout in html-mode

[Chris Withers]

Hi All,

In html-mode, how can I get the html layed out out sensibly?
(ie: I'm starting off with a file that has weird tabbing, spacing, etc, 
all over the place and I want it all normalised)

cheers,

Chris

Using html-helper-mode, doing C-i properly indents the current line.  So
 in such files I start with the point on the first line, do C-i, then do
the same on the second line, and so on.  This of course doesn't work if
all the html code is on one line.  The tags and text you want to indent
properly must lie at the beginning of a new line (optionally with some
white space preceding it); that is, C-i won't insert newlines at proper
locations.  ("Proper location" is not an objective determination
anyway.)  But html-helper-mode does understand opening and closing tags
and (normally) indents these at the same level.

hth,

Thanks, but I'm looking for something more like:
- select region
- M-x unsuck-html-layout

You're looking for `indent-region' which is bound to C-M-\. I'm using
it with html-mode, works great.

I'm hoping for something internal to emacs as, for tedious but 
unchangeable reasons, I'm stuck running on Windows...

I don't know at the moment how to pipe a region through an external
process, but that should be feasible. Xmllint does a nice job at what
you are trying:

  xmllint --html --format <your html file here>

Maybe others could chime in as to how one could pass the region (or the
whole buffer) through an external program?

As Anselm pointed out upthread, indent-region might work for you. Alas,
it doesn't take apart long lines.

You have my most sincere condolences.

(but: xmllint, part of the libxml2 suite should be available on Windows)

If the external program can be invoked as a standard filter then M-| 
(shell-command-on-region) might work. I ran it with sort and a sorted 
region was written to a new *Shell Command Output* buffer.
