For me personally, my preference is still on manually marking what
goes into the Gettext pot file and I believe my idea for its syntax is
suitable.

For example, this is a multi-part internationalized paragraph from my
website:

(p ,@(__ "“Don’t Hang” by default uses the words from \
the ||ic_|/usr/share/dict|| directory, but it can deal with any list of \
expressions in a text file with one expression per line. ||samplelink_|Here|| \
is an example word list file compiled with words from \
||wiktionarylink_|Wiktionary’s list of 1000 basic English words|| which you \
can use if you want simpler words. This sample word list is available under \
the terms of ||ccbysalink_|the CC-BY-SA 3.0 Unported license||, because \
Wiktionary uses this license and the words are taken from there."
         `(("ic_" .
            ,(lambda (text)
               `(span (@ (class "inline-code"))
                      ,text)))
           ("samplelink_" .
            ,(lambda (text)
               (a-href
                "sample-word-lists/english-words.txt"
                text)))
           ("wiktionarylink_" .
            ,(lambda (text)
               (a-href
                "https://en.wiktionary.org/wiki/Appendix: 1000_b\
asic_English_words"
                text)))
           ("ccbysalink_" .
            ,(lambda (text)
               (a-href
                "sample-word-lists/CCBYSA-3.0-UNPORTED.txt"
                text))))))

But since there seems to be a demand for automatic extraction without
marking each piece of translatable text, maybe Haunt should offer that
as well.  This would involve deciding which parts of a Scheme file are
SHTML code and which parts are just Scheme.  Maybe that can mostly be
deduced from context but some false positives may need to be dealt
with.  Also in SHTML code there is the issue of whether e.g. URLs
should go into the pot file or not.

I will take a look at Haunt and upstreaming next week.  Currently my
main concern is build system integration.  I want to just run „ninja
mywebsite-pot“ to build the pot file.  But GNU Autotools are
complicated, Meson/Ninja depend on Python and probably Haunt should
integrate with each of them eventually…
