sjasmplus v1.20.0

1.20.0 - 13.6.2022

• Lua: upgrade to 5.4, replacing tolua++ bindings with LuaBridge2.6 library, extending some bindings
• Lua: bindings slightly modified (required by upgrade), refreshed docs, added test coverage
• Lua: the 3rd party extensions (BTW not working for many years) are obsolete in 5.4 and removed
• Lua: more accurate errors/warning location reported even in complex cases
• warnings: added -Wall, --help=warnings shows on/off status, rdlow off by default
• Added HIGH mode to relocation data generator (MSB-only relocation mode)
• many open-file "fatal" errors become "non-fatal", assembling will continue
• deprecated features removed: --syntax=m, label abs in expressions
• --color=auto will stay no-color when env.var. NO_COLOR is defined
• refactorings, improving some error messages and parsing, small fixes in parsing logic
• fix listing of Lua's sj.parse_code (eol-comments), minor memory leaks fixed
• fix relocation of temporary labels in expressions
• invalid CLI options are reported as regular errors (also changing exit code)
• errors are colored similarly to gcc (only keyword has color), console input name is <stdin>
