assembler, branch v2.1.0Rust library for parsing assembly languageshttps://code.benbridle.com/assembler/atom?h=v2.1.02025-03-11T03:18:33ZUpdate version to 2.1.02025-03-11T03:18:33ZBen Bridleben@derelict.engineering2025-03-11T03:18:33Zurn:sha1:c5f60b7ff45ced7c8b8519bc8fcf681486ad09faImplement source chains2025-03-11T03:18:01ZBen Bridleben@derelict.engineering2025-03-11T03:18:01Zurn:sha1:a9e9dd452e23fa2e816df926a56c1f743eb32488
A SourceSpan can now contain a child SourceSpan, ad infinitum, in order
to represent a chain of locations. The report_source_issue function
has been changed to print the entire chain, instead of just one
SourceSpan.
The report_source_issue function has also been changed to correctly
print SourceSpans that extend across multiple source lines.
Prevent duplicate parent and child entries for source units2025-03-11T03:13:23ZBen Bridleben@derelict.engineering2025-03-11T03:13:23Zurn:sha1:bd7955cbc1c1746f37dcb0742603994fd2e04c90
The parent and child collections for hierarchical source units were
previously vecs, and would receive one entry for every symbol matched.
This was easily leading to many dozens of duplicate entries per unit,
which, while not impacting performance, seemed wasteful. The collection
types were changed to HashSets to prevent the collection of duplicate
entries.
Make output of report_source_issue more concise2025-03-10T03:31:06ZBen Bridleben@derelict.engineering2025-03-10T03:31:06Zurn:sha1:6fb6f2836232fe78dce507fa899629bbefb7b449
Instead of displaying two locations for the same error, only show the
in_merged source location if there is no in_source location.
Implement Borrow and BorrowMut for Tracked2025-03-09T05:20:06ZBen Bridleben@derelict.engineering2025-03-09T05:20:06Zurn:sha1:5e332adb606074da1976c8ce6e32b94ba222bc82Make Tokeniser::eat_until even more general2025-03-08T03:48:33ZBen Bridleben@derelict.engineering2025-03-08T03:48:33Zurn:sha1:53dffaf3fe18f70151b23418ff80ae8904fae779
The eat_until method of Tokeniser has been renamed to track_until, and
it no longer consumes characters by itself. The predicate closure is no
longer limited to checking one character at a time, it can look ahead
for multi-character sequences when used with the new eat_if method.
Add Tokeniser::eat_if method2025-03-08T03:46:18ZBen Bridleben@derelict.engineering2025-03-08T03:46:18Zurn:sha1:e1dea1faf3e29655c008bf139d2a9acf3229df53
This method is used for consuming a multi-character sequence only if
that sequence matches a passed string.

There is the possibility that the same source file could be discovered
twice, if the same folder is included multiple times as a library folder
or if symbolic links are used that link to already-included files. These
duplicate source files are now ignored, to prevent erroneous 'duplicate
definition' errors from being generated.
Show an error when a source file fails to parse2025-03-08T01:22:53ZBen Bridleben@derelict.engineering2025-03-08T01:22:38Zurn:sha1:869d9b4b9c6f5d095084c851af33d8590bd3edee
Previously, if a source file failed to parse, no symbols would be
returned and symbol resolution would continue as normal. This would
obscure the source of any errors, as well as the fact that any error
had occurred at all.
We don't want all errors in all source files to be printed at symbol
resolution time, because this could bury any errors in the actual
program being assembled with potentially irrelevant library errors,
and errors in the program being assembled will be printed all over
again once a merged source file has been produced.
Instead, we allow the parser function to return a None value if the
file could not be parsed, and a single line is printed as a warning
for every library file that failed to parse.
