Logically, i18n.merge_file cannot ever take a MULTI_OUTPUT_KW, but it
does take a CT_OUTPUT_KW-like interface.
Actually trying to pass multiple merge_file outputs causes the
msgfmthelper script to be entirely malformed in the arguments it
accepts, and treat the broken one like a --flag, then exit with argparse
errors.
Even if we somehow assumed that somehow it was designed to actually
allow this, msgfmt doesn't support conceptually passing multiple outputs
so that would be a msgfmt error instead of an error inside the guts of
`meson --internal msgfmthelper`.
Same logic applies again for the itstool command and the itstool
internal helper.
Catch this error at configuration time by using the single-output kwarg
form.
Likewise, it's totally nonsense to accept multiple install_dir or
install_tags, and ever since commit 11f9638035
the CustomTarget itself won't even check this.
Meson Documentation
Build dependencies
Meson uses itself and hotdoc for generating documentation.
Minimum required version of hotdoc is 0.8.9.
Instructions on how to install hotdoc are here.
Building the documentation
From the Meson repository root dir:
$ cd docs/
$ meson setup built_docs/
$ ninja -C built_docs/
Now you should be able to open the documentation locally
built_docs/Meson documentation-doc/html/index.html
Upload
Meson uses the git-upload hotdoc plugin which basically removes the html pages and replaces with the new content.
You can simply run:
$ ninja -C built_docs/ upload
