==================
It's time to release a version now. People are looking for fixes which were in
trunk for a long time now.
**Fixes**
* Paths with parent references don't give bogus portability warnings any more
On Windows the due to an oversight parent referencing paths incorrectly
triggered the portability warning originally intended for detecting a
filename case mismatch.
* Arbitrary length int right shift was wrong in some cases.
Now it's correct.
* .bfor didn't accepted .endfor closing in some cases
Now it's correct. Did always work with .next and I didn't transitioned the
test sources...
* (0, x) is now recognized as indexed indirect for opcodes
The parser of course did recognize (0,x) just fine for opcodes. However
writing (0, x) is a tuple and so does something else. There's a workaround
now to recognize such a construct as indexed indirect instead. This should
avoid bad surprises for those unaware that the indexing operator should not
have a white space there.
* Writing to standard output suppresses messages in all cases
This only worked for output files but now for everything (e.g. listing
to "-" didn't suppressed messages while --output "-" did).
* The TASM compatibility text macro parameter expansion was wrong
It didn't remove the quotes from strings. It broke quite long ago, now
works again.
* Output append didn't reproduce gaps working correctly in some cases
Padding was corrected and now it does.
* Output could have garbage in gaps on non-POSIX conforming systems
Unlikely anyone got that far in porting but gaps should be correctly
filled with zeros now
**Changes**
* JMP and JML are distinct now
JMP could be unexpectedly upgraded to JML in some cases (e.g. bank 0 address in
another program bank) which is bad as the program bank will be changed when
that happens. Now it's consistent with JSR/JSL.
* label = 1,2,3 is the tuple (1,2,3) now
That makes it actually useful for something. Before it was an object
with one couldn't do much with.
* .switch and .if blocks labels have size now
Everything else with regular code blocks worked that way already.
* %c in format() applies padding now
For consistency with the rest of the format parameters.
* Oversize integer diagnostic in bytes and bits now
It was in bits all the time but if the limit was set in bytes it makes
sense to give the error in bytes as well.
* Compound assignments can now change variables in parent scope
Without this using .bwhile is a pain as the loop condition variable is
usually declared out of the loop (and so the scope).
* The memory map was improved or at least is different now.
With the former memory map there were lots of redundancy if one used
sections. It was even worse with nested sections. The new memory map
tries to display overlaps more compact. However for most people with simple
projects the difference would be the length display in decimal on the left
and that gaps between data areas are shown now.
* Per output memory map, also writable to file.
The memory map was global before. Now if a specific section is output
then only the relevant parts of the map is shown. This also means that
if there are multiple output files then there are as many memory maps.
As a side effect .virtual blocks aren't displayed any more as these
don't really belong to an output file.
* The .enc directive now requires an expression
In the past one could write the name of encodings without quotes. Soon there
was a need to allow labels to hold a name so there was a warning to quote the
names for the past 5 years or so. Now that custom encodings can be assigned
to labels there's an even greater need to be able to use labels. Therefore
the old style unquoted encoding names will be now interpreted as labels and
will likely fail to be found. Please quote the old name or as a workaround
define the missing labels with a string of the encoding name (e.g screen =
"screen").
**New**
* .symbol in namespace
Now it's possible to check if a variable exists in a namespace. May be useful
to check if a variable is defined. No, this does not work with constant
definitions.
* Function parameter conversion
This allows to have a parameter like "data : binary" which calls
binary() and its result is assigned to the parameter. This allows to
load data relative to the caller's file and not relative to the file the
function is located in.
* !in and !== operator
Instead of !(a in b) now it's possible to write a !in b. Also the ===
operator got its !== pair.
* Multi operand opcodes do broadcast now
It was only working for single operand ones so far, now it's consistent.
* Bit strings can be iterated now
Just like character and byte strings did already
* ::= reassign operator
This can change a variable in parent scope. Unlike := which instead
would create/update a variable in the current scope instead.
* Better reporting of unexpected characters
Strings should be quoted with straight quotes. Using fancy quotes did
result in an error but it was difficult to make sense of it as the
difference is hard to spot. Now the diagnostic is more clear.
* --mos-hex for MOS Technology HEX format
There was Intel and Motorola before but not MOS yet. There are 6502 platforms
needing this.
* --list-append added
Now listing can be appended too, just in case.
* .encode/.endencode encoding area
This allows to have local encoding definitions. Such definitions can be
assigned to a label to allow reuse in other areas. Can be used as string
conversion function as well.
* Added .tdef for easier encoding definition
It was not easy to define translation for randomly scattered Unicode
characters so far as .cdef was made for ranges like A-Z. One had to
define a bunch of single character ranges but such a workaround can be
replaced now. |
