rpn v2.5

Added

• A new command endl, meaning end-line was added for line formatting sake. #269
• Clang compilation is now warning-free (tested with clang 14.0). #274
• Program run now optimized. Programs were parsed then linked at each run ; now the parsing and linking phases are done only once at entry time, avoiding terrible performance loss. #267
• Contrary to what was said in version 2.4, some rpm and deb packages are attached to this delivery, thanks to multi-distro-packager 🤩

Changed

• C++20 standard is used instead of C++17. This detected some warnings (now corrected). #268

Fixed

• Syntax errors (and other errors) are now shown after the stack, which is much more convenient. #273
• Warnings shown by clang and C++20 (braces initializers, some bad types, removed dangerous #pragma). #268, #274
• The linenoise-ng submodule version was well set in CMakeLists.txt but not in the submodule, which showed a permanent linenoise-ng modification in git although the version was the good one. #277

Fixed

rpn v2.4

rpn v2.4 is a major delivery as it holds a big code refactoring, mainly for maintainance reasons.

Despite significant changes to the code as well as some compatibility losses with version 2.3.2, the major version of the software has not changed, as no major new features have been added.

Here is the extract of the newly added CHANGELOG.md about this version.

Added

• Better parser (in fact just a lexer, because that's all it takes).
• Use of mpreal instead of raw mpfr for calc on reals.
• Use of the standard C++ complex class.
• Enhanced code quality and memory usage checks.
• Added github actions to pass functional tests and valgrind mem checks at each pull request.
• Applied google c++ style guide
  • points covered are very numerous: c++17, define guard, name and order of inclusions, static and global variables, common patterns, classes, naming conventions etc.
  • cpplint used with a CPPLINT.cfg removing some warnings.
  • clang-format is now based on google style.
• Test files are now markdown (.md) files, tests result are slightly changed.
• Delived as flatpak, not as rpm and deb anymore.
• Automatic version string from git.
• hex and bin numbers accept floating point input and C99 standard output.
• « and » are now valid as program delimiters. << and >> are still valid.
• Entering the sign after the base (ex: 0x-1e2) is allowed.

Changed

Be carefull, compatibility is broken on these points compared to last version 2.3.2:

• << << input doesn't lead to ««»» but to «<< », preventing to eval the real program content.
• Making an operation stick to the previous entry is not possible anymore (ex: 1 2+ instead of 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).
• The binary prefix is always 0b on display, but the input can be 0b, 0B, 2b or 2B.
• The hex prefix is always 0x on display, but the input 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 the 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.

Removed

• Removed useless unti, repea, whil (prev. existing for HP28S compatibility).
• Removed sqr function, please use sq instead (prev. existing for HP28S compatibility).
• Removed CtrlC for interrupting a program (considered useless).
• Removed old memory management, efficient but poorly maintainable.
• Removed man page generation.

Fixed

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

rpn v2.3.2

rpn v2.3.2 corrects some bugs of v2.3.1

• numbers as loop variables: could wrongly exclude boundaries: #112
• negating a hex number causes a crash: #201

It also add some commands which were planned in v2.3 but were forgotten

• stack depth is no more marked on each line if rpn is used with arguments: #209
• Ctrl-C with text already entered should only clear this text and go back to prompt: #146
• New REAL commands expm and lnp1: #192
• New commands: date, time, ticks: #8
• Multiline editing: #147, #154

A quite big code refactoring has also be done: #210, #211, #212, #213, #214
