RPL/2

RPL/2 is a special programming language for scientific computations, and could be the strange child of forbidden love between Lisp and Forth.

The usable and working data types are as follows:

- Binary integers (64 bits);
- Signed integers (64 bits);
- Real numbers (64 bits);
- Complex numbers (2*64 bits);
- Strings (any length);
- Lists;
- Complex,real or integer vectors;
- Complex,real or integer matrices;
- Names;
- Algebraic expressions;
- Expressions stated in reverse polish notation.

What is new in this release:

• OpenMotif is now patched to correctly detect fontconfig.
• Sqlite and ncurses are updated. rpl.inc is fixed.
• rpl() now sends arguments to RPL/2 subroutines.
• The rpl() prototype is fixed (rpl_home is an unsigned char *, not an unsigned char **).
• GSL is upgraded.
• A major bug is fixed in the READ intrinsic (it only occurs on Unix devices).

What is new in version 4.1.16:

• OpenMotif is now patched to correctly detect fontconfig.
• Sqlite and ncurses are updated. rpl.inc is fixed.
• rpl() now sends arguments to RPL/2 subroutines.
• The rpl() prototype is fixed (rpl_home is an unsigned char *, not an unsigned char **).
• GSL is upgraded.
• A major bug is fixed in the READ intrinsic (it only occurs on Unix devices).

What is new in version 4.1.15:

• RGDL and RGDR (ragged left and ragged right) new intrinsic functions have been added since 4.1.14.
• A major bug is fixed in the initialization sequence (segfault).
• It only occurs when RPL/2 is built with a forced localization.
• EXIT regression is fixed,

What is new in version 4.1.14:

• The number of pipes between process was reduced.
• Gnuplot was upgraded and patched so that it can be built without a texinfo error.
• Libiconv was patched to support recent GLIBC (C11) versions.
• Some race conditions were fixed. Sqlite was upgraded.
• Major regressions were fixed in the IFERR/END structure and inin evaluation().
• Local variables were exported to called definitions.
• All users should upgrade to this release.

What is new in version 4.1.13:

• This version contains a lot of bugfixes and some minor improvements. All users should upgrade to 4.1.13.

What is new in version 4.1.12:

• A minor bug inrecherche_type() was fixed. { "\"" } was not evaluated as expected as an inner quote was not escaped.
• A new CIPHER intrinsic was added for performing key generation, decryption, and encryption.
• CBC-CMAC and HMAC digests were added.
• A DIGEST intrinsic was added.
• Signal management on NetBSD was fixed.
• RPL/CAS auto-configuration is upgraded.
• SQLITE support was added in SQLQUERY, SQLCONNECT, and SQLDISCONNECT.

What is new in version 4.1.11:

• Shared and static variables are now stored in a tree.
• Only giac/src is built in rplcas (giac/Makefile.am is modified).
• Gnuplot, lapack, giac, units, and ncurses are upgraded.
• Interprocess capabilities are removed when RPL/2 cannot run its initialization routine to keep operating system as clean as possible.
• Signal management is rewritten to avoid a strange bug on NetBSD where a signal handler can be called within a special thread and not in the calling thread.
• A major bug is fixed in STO intrinsic.
• STO returns an error when it has to create a global variable if intrinsic none (default) is set.

What is new in version 4.1.10:

• FORALL intrinsic is added.
• A major bug (deadlock) is fixed in CYCLE that only occurred when CYCLE is called to interrupt a loop from a subroutine within a compiled program.
• There is a workaround to avoid strange bug on slow networks in READ intrinsic.
• CRITICAL/END structure is added.
• When a program enters in a critical section, all other threads of the same process sleep until the program leaves the critical section.

What is new in version 4.1.9:

• Tools are upgraded (giac, ncurses, sqlite, units, and lapack).
• LENGTH*(...) format is fixed.
• Some patches have been added to build RPL/2 on NetBSD.
• Escaped characters are fixed in READ and WRITE operations.
• A major bug is fixed in READ intrinsic (on socket) as End Of File condition was randomly caught on slow networks.
• stdin can now handle espaced characters strings in SYSEVAL.
• --with-gcc-version is added to the configure script to force the gcc version, as gfortran 4.7 is broken and crashes with a segmentation fault.

What is new in version 4.1.7:

• Some minor bugs are fixed.
• Double quotes are escaped in INPUT and PROMPT intrinsic functions.
• An error is returned (instead of a warning) when an unavailable intrinsic function is called.
• RPL/2 can now be cross compiled until Debian archive generation.
• All table, vector, and matrix dimensions are now treated as unsigned long.
• The recherche_type() function is modified to use cached memory.
