Changelog

• Better parser (now called lexer)
• Use of mpreal instead of raw mpfr for calc on reals
• Use of C++ complex class
• Removing old memory management, efficient but poorly maintainable
• Enhanced code quality and memory usage checks
• Added CircleCI checks: passing functional tests and valgrind mem checks at each pull request
• SonarCloud integration, Sonar way profile
• clang-format now based on google style
• google c++ style guide applied
  • c++17
  • define guard
  • name and order of inclusions
  • static and global variables
    • common patterns (ex: no static maps or vectors)
  • classes (explicit)
  • naming:
    • file names (.cc .h), types (PascalCase), variables (snake_case), members (trailing _), static const (camelCase begining with k), enum (enum class, values like static const
    • consistent comments (//), class comments, functions comments
  • cpplint used with a CPPLINT.cfg removing some warnings
• Test files are now markdown (.md) files, tests result are slightly changed
• Delivery as flatpak and snap
• error string are slightly different, althought error codes are still the same

New

• « and » are now valid as program delimiters. << and >> are still valid
• entering the sign after the base (ex: 0x-1e2) is allowed
• rpn is delivered as flatpak and snap packages to be compatible with a maximum of Linux distribs. rpm and deb are no longer generated

Compatibility is broken on these points

• << << input doesn't lead to ««»» but to «<< », preventing to eval the real program content
• 1 2+ not allowed anymore, keep 1 2 +, this corrects bad behaviors like 3b114 pushing 3b11 and 4
• complexes are written in the form (1,2) instead of (1, 2) (space is removed)
• removed useless unti, repea, whil (prev.existing for HP28S compatibility)
• removed sqr function, please use sq instead (prev.existing for HP28S compatibility)
• the binary prefix is always 0b on display, but still can be 0b, 0B, 2b or 2B at input
• the hex prefix is always 0x on display, but still can be 0x, 0X or 16B at input
• mant and xpon now give binary (and not decimal) significand and exponent, as it is the norm in standard libs (libC, standard C++, mpfr, gmp)
• dupn, roll, rolld are not leaving anymore their argument in front of the stack in case of error
• sto+ sto- sto* sto/ don't accept anymore the syntax 'varname' value stoX, but only value 'varname' stoX, ex: 3 'a' sto*
• incomplete entry (1, is not available anymore
• signed zero is the sign of zero is subject to change compared to previous version, for example -3 sqrt now equals (0.000000,1.732051) instead of (-0.000000,1.732051)
• removed CtrlC for interrupting a program (considered useless)

Debug

• sub now only accepts boundaries between 1 and the string length
• sto/ behavior: sto/ now correctly stores variable / constant and not constant / variable
• cosh now returns the hyp cosinus instead of the hyp sinus (!)
