As you might expect with the initial release in a new series, there are some
changes that break compatibility with previous versions. The two main ones are
that the ability to generate a control file has moved from
sna2ctl.py command, and that
skool2html.py now expects a skool file
as its first positional argument, and treats any remaining positional arguments
as extra ref files. For details on the other ways that SkoolKit 7 might break
your disassembly, and how to fix it, see the
But enough of that. What new features does this release bring? Well, again, as with the compatibility-breaking changes, there are two main ones, and they both serve a purpose that has long been dear to my heart: preservability in a control file. It has always irked me that some parts of some skool files are not amenable to such preservation, but with the advent of 7.0 those parts (and those skool files) are thankfully smaller in number.
First of all, the
directives have gained some key new abilities. They can now specify a
replacement comment over multiple lines, replace labels, and insert, overwrite
and remove instructions. Previously, each of these operations would have
required the use of a block directive (e.g.
cannot be preserved in a control file.
Second of all, non-entry blocks (i.e. blocks that do not match the format of an
entry, such as a header comment) are now preserved verbatim by
and are reproduced verbatim (minus any ASM directives) by
means that comment blocks appearing between entries in a skool file will now
survive a round trip through
sna2skool.py, even if they
contain ASM block directives.
Third of all, although I said there were only two main new features, there is
one more that is relevant to the central theme of preservability in a control
file, and so deserves a mention here. Inverted characters - meaning character
codes with bit 7 set to indicate the end of a string - can now be stored in and
restored from a control file. So, for example, the
"Hell","o"+$80 will survive the round trip, instead of degrading to
And that is it, as far as preservability in a control file is concerned. For details on all the other much less important features - which, I warn you, may have nothing to do with either preservability or control files - take a look at the changelog. Happy migrating!
