I have some HTML code, which I generate using x-expressions:
(string-append DOCTYPE-HTML5
"\n"
(xexpr->string
`(html
(body ((bgcolor "red"))
"Hi!" (br) "Bye!"))))
I don't like how the result looks in the source code of the web page created in
this way. I'd like there to be indentation and line breaks, according to the
nesting of the DOM elements.
So far I've found the following links and information:
- https://docs.racket-lang.org/reference/pretty-print.html (I don't know how to
use it, because it has no examples. It also seems more like a library, which
generically can pretty print anything you want, provided you "configure" is
correctly. However, HTML is quite complex, I think, so I'd not like to rewrite
something that already exists elsewhere.)
- https://docs.racket-lang.org/xml/ (Here are some mentions of indentation and
newlines, but I need some procedure, which returns it, not displays it
immediately and then "does not let me have it", or is there a way to somehow
redirect output into a value which I can use? For example `display-xml` seems
to do what I need. :)
Ideal might be a keyword parameter for `xexpr->string`, which specifies whether
it should prettify the string or not, but such a thing does not exist according
to the docs.
How can I prettify my HTML output?
(I really don't care about a few bytes more data needing to be sent. This is
not the next Google.)
