I think it makes sense to make these customizable, but I wonder if
it makes the result easier to maintain if we make units of logical
definitions larger, e.g.
ASCIIDOC = asciidoc
TXT_TO_MANHTML = $(ASCIIDOC) -b xhtml11 -d manpage $(ASCIIDOC_CONF)
TXT_TO_ARTICLE = $(ASCIIDOC) -b docbook -d article
...
ASCIIDOC_EXTRA may want to apply all of them, even though I see that
we do not feed it to OBSOLETE_HTML right now. It may also be that
$(ASCIIDOC_CONF) and -agit_version=$(GIT_VERSION) could be shared
among the ones that currently do not have.
Then the above would become something like:
ASCIIDOC = asciidoc
ASCIIDOC_COMMON = $(ASCIIDOC) \
$(ASCIIDOC_EXTRA) $(ASCIIDOC_CONF) -agit_version=$(GIT_VERSION)
TXT_TO_MANHTML = $(ASCIIDOC_COMMON) -b xhtml11 -d manpage
...
and would further simplify this part
> $(MAN_HTML): %.html : %.txt asciidoc.conf
> $(QUIET_ASCIIDOC)$(RM) $@+ $@ && \
> - $(ASCIIDOC) -b xhtml11 -d manpage -f asciidoc.conf \
> + $(ASCIIDOC) -b $(ASCIIDOC_HTML) -d manpage $(ASCIIDOC_CONF) \
> $(ASCIIDOC_EXTRA) -agit_version=$(GIT_VERSION) -o $@+ $< && \
into just
$(TXT_TO_MANHTML) -o $@+ $<
After all, our output formats are fairly limited, I would think.
Are there too many different variants and exceptions to make such an
approach infeasible?
