Invited

Just started in on conversations regarding taking on a co-admin role with the Unicon project. Honoured, and looking forward. If it works out, and there is no reason to think it won’t, the Unicon Programming docset will be moved to SourceForge and become part of the Unicon project proper.

I have plans to leverage some of the offerings provided by the great people at SourceForge. And to continue to advocate the use of Unicon for generating solutions to modern computing needs.

Recent news

The Unicon Programming doc set is still progressing along nicely. The alpha status warning has been dropped and the version bumped to 0.2. The todo list is shrinking, and growing. Shrinking in terms of getting all the reference material in place, growing in terms of all the nifty application potentials for Unicon programming that await discovery and implementation.

List support in repl

Clinton Jeffery has recently updated the repl function to support List data.

link lists
procedure main()
    L := [1,2,3]
    write(limage(L))
    write(limage(repl(L, 3)))
end

That code will replicate the list L three times, giving a result of

[1,2,3,1,2,3,1,2,3]

A handy feature.

More loadfunc

Created a sample that embeds ficl, the Forth Inspired Command Language, a shared library that exposes a very nice Forth engine. unificl embeds the interpreter for use from Unicon.

See ficl for all the details.

Linux Containers

Jafar Al-Gharaibeh has created a layer that allows Unicon to interface with LXC, the Linux Container system. This allows sandbox operations and container management in a few lines of Unicon source.

Vim editor syntax file

A Unicon specific highlighter has been created for use inside the Vim editor. Builds on the existing Icon syntax file that ships with Vim, adding in Unicon specific (and Icon graphic) reserved words, keywords and function lists.

Graphics fixes

Reported some issues with 3D graphic support on GNU/Linux systems, and within a few days, Clinton and Jafar had fixes posted. More attributes work properly with the open function, and WriteImage can now be used to capture the result of a 3D graphic canvas, saved in any of the many supported image formats.

The Unicon project continues to improve. Nice.

Have good, make well.
