Even when the virtual pointer is hidden in KaiOS, it still causes :hover
on whatever element is nominally under it, which is confusing. Disable
all the :hover effects as a workaround.
This only happens if something edits manifest.pl to provide a version
number, but Buildscr can do that. KaiOS manifests are documented as
requiring dotted-decimal version numbers. In fact, the restrictions are
much stricter than that, and unacceptable version numbers can break the
KaiStore developer portal. YY.MM.DD version numbers seem to be
acceptable.
They're proving to be a right nuisance and will probably require a
substantial overhaul to how they work across the entire JavaScript
front-end. I don't think any of the functionality provided by the
dialogue boxes is critical, so in the interests of getting a minimum
viable product actually released I've disabled those features.
In most cases, this just involves commenting out bits of HTML. The
"Custom..." menu item is added by C code, though, so there I've fallen
back to the standard Puzzles way to implement a nasty hack: an
environment variable.
KaiOS (which is based on Firefox OS, formerly Boot to Gecko) runs its
"native" apps in a Web browser, so this is essentially a rather
specialised version of the JavaScript front-end. Indeed, the JavaScript
and C parts are the same as the Web version.
There are three major parts that are specific to the KaiOS build.
First, there's manifest.pl, which generates a KaiOS-specific JSON
manifest describing each puzzle.
Second, there's a new HTML page generator, apppage.pl, that generates an
HTML page that is much less like a Web page, and much more like an
application, than the one generated by jspage.pl. It expects to build a
single HTML page at a time and gets all its limited knowledge of the
environment from its command line. This makes it gratuitously different
from jspage.pl and javapage.pl, but makes it easier to run from the
build system.
And finally, there's the CMake glue that assembles the necessary parts
for each application in a directory. This includes the manifest, the
HTML, the JavaScript, the KaiOS-specific icons (generated as part of the
GTK build) and a copy of the HTML documentation. The directory is
assembled using CMake's install() function, and can be installed on a
KaiOS device using the developer tools.
