New release 4.1.24 with some bugfixes... Please test.

New release : RPL/2 4.1.25 at http://www.rpl2.net.

Enjoy !

[compsystems]

I can not even enjoy because I'm using Windows-OS. Why can not you please start a compatible way of libraries windows-linux as wxWidgets?

can I use, please, your picture http://www.rpl2.net/img/screen2.png of your website in an article that i am writing of RPL programming?

Thanks

I don't understand. RPL/2 only uses Motif if you write graphical applications. In other case, it's only a text-based application and a simple terminal is enough. You can build RPL/2 under Windows with Cygwin.

Of course, you can use http://www.rpl2.net/img/screen[1-4].png. Please indicate sources.

Last daily snapshot can be built and runs on Windows 10 (64 bits) under Cygwin with PostgreSQL, mySQL/MariaDB and RPL/CAS support. I have seen some issues with signals management but these issues come from WIndows or Cygwin, not from RPL/2 code.

I haven't tested with Foreign Linux.

Some news.

For a long time, it was possible to write libraries to add new functionalities into RPL/2. In 4.1.27, it is possible to manage new types in these libraries.

RPL/2 is now shipped with two libraries. The first one motif$ is used to create graphical applications. The second one, sets$, is able to work on sets and defines a new type with ([ ]) delimiters and five new instructions :
- complement
- union
- intersection
- s->l (set to list)
- l->s (list to set)

Example :

Code:


#!/usr/local/bin/rpl -sp -m sets.rplso

TEST
<<
        externals disp

        ([ 1 2 3 4 5 6 7 8 9 ]) ([ 3 6 8 ]) complement disp
        ([ 1 2 8 9 ]) ([ 3 6 8 ]) union disp
        ([ 1 2 8 9 ]) ([ 3 6 ]) intersection disp

        ([ 1 2 3 0 ]) disp
        ([ 1 2 3 5 ]) s->l disp
        { 1 2 2 5 1 2 } l->s disp

        clmf
>>

that returns :

Code:

Nice effort! I though it was going to be discontinued!

Actually I want to make my RPL terminal calculator but it may be redundant since there is yours.

[JKB]

I've never said it is going to be discontinued. I have only written I don't know if I will continue to develop this application as I have no return (bugzilla for example), no traffic on mailing list...

[pier4r]

well you may expect that, without involving (read: sort of mentioning often) the work in the communities that likes RPL, it is difficult someone will use it/contribute.

Also I guess newRPL may be a competitor (although with gui).

Also the lack of binaries or "ready to use" programs may hinder those with little time.

I mean you added database support or even CGI support. That is quite a lot.

In core RPL/2 support sequential, direct access and keyed files. In core, it also supports sqlite3 database. And you can directly access to mariadb/mysql or postgresql if you configure RPL/2 at build stage.

I have written a long time ago (for 4.0) a CGI support to connect RPL/2 to a regular apache2 server. I'm not sure this module is usable without serious modifications.

I'm not sure that newRPL is a competitor. RPL/2 was created to write scientific programs on multithreaded servers (in a first time on DEC-Alpha with 4 CPU, in a second time on Sparc with 64 CPU) and targets of both languages are very different. Thus, it doesn't require a GUI.

[pier4r]

well both projects are quite a work, I never used yours so far but surely looks polished. I would be extra proud of it.

Hello,

I have just released RPL/2 4.1.27 (http://www.rpl2.net)

Some news : it is now possible to manage new types from external libraries (see modules/sets and modules/motifs). RPL/2 is now shipped with two external libraries : motif (to write graphic applications) and sets (to handle sets). Examples are available in sources directories.

Two major bugs have been fixed :
- when allocation size was null, there was a buffer overflow (8 bytes);
- DETACH works now as expected (for a long time, DETACH was replaced by SPAWN if experimental-code flag was disabled).

Enjoy,

JKB

So, started to use the last version of the 4.0 release (because: Xp is the OS that I use for HP50g related stuff. Indeed newRPL 0.9 does not work, snort. So to be safe I normally take not the last version but the last version of the last release published when winXp was still widely used).

As said before, the work done is really a lot, congrats (I love people like you or Claudio that share with everyone).

I have Cygwin 2.5.2.

One small report, I am not sure it is fixed in the 4.1.x version. If the configure script does not found commands (like "patch") maybe it should fail to avoid messing up the installation?

edit: after like one hour of compilation. make fails due to "cmp" missing. Once again, would be nice to have a test at the start that verifies that needed commands are there, working, and if not, quits the installation with a message. (I am not sure this is present in 4.1.x but I would bet not)

(for those like me that wants to install the last cygwin on winXP: http://www.crouchingtigerhiddenfruitbat....chine.html )

also bugzilla (I know the workaround, but people may be pushed away):

Done. configure script now looks for patch.

Which version did you try to build ? Can you post error message ? I don't have Windows thus it can remain some side effects...

I used the last version of rpl/2 . 4.0.23 (this because I use winXP and cygwin 2.5.2, the last for winXP).

I ma not sure about the requirements, if the last version of RPL/2 can work on cygwin 2.5.2 then I am set. Also I have debian systems as well (but debian 6.0.10) is debian 6.0.10 compatible or is it too old?

For the error messages I have to go through the compilation procedure again and, well, not today (It takes really long time*). I will do it again though, so I hope within this week to post something.

* This is what is frustrating. One waits hours and then the procedure fails for some missing command.

Last stable release is 4.1.27, if I remember. A lof of bugs and new features have been fixed or added since 4.0.23.

For Debian, I suppose you can try to build RPL/2 on Debian 6, but this distribution is now old and if you haven't all requirements, I'm not sure you can install them without rebuild them from sources.
