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](https://google.github.io/styleguide/cppguide.html) 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 (!)
