Notes - MetaCommunity.info fork of McCLIM

Towards developing an application framework for supporting a platform-agnostic approach to development of graphical desktop applications in Common Lisp, I've made a fork of the McCLIM codebase, organizing the codebase under the MetaCommunity projects group at Github. Corresponding with so much as the maintenance updates in the fork, I've also begun to keep an issue tracker with YouTrack, under the hosted YouTrack InCloud service, At this time, I would not request contributions about of those endeavors. This is simply a note that I would like to share, regarding such existing work.

Insofar as keeping track of the aims and goals of the development of the MetaCommunity.info (MCi) fork of McCLIM, whereas the project comprised of the fork does not yet "Fit" into any specific heading within the two main MetaCommunity.info projects groups -- respectively, the Clyde projects, named after the Firth of Clyde, directed  mostly towards applications in mathematics and electrical engineering, and the Fourier projects, named after Charles Fourier, those to be focused mostly about literacy, tourism, and ethical conservationism, so far time and focus permit -- so, instead of documenting this small effort, presently, at the MetaCommunity.info work journal,  instead I thought it would be appropriate to publish this outline, here at DSP42.

So, with that much of adieu, my notes about the MCi McCLIM fork.

The main points of focus in the development of the MCi McCLIM fork are as follows:
  • Maintenance updates
  • Documentation
  • Usage cases
    • Scigraph
    • Extensions: ??? 
      • Usage cases on the BeaglBone Black platform (ARM) in applications of BBB TFT LCDs
        • Application: Multi-headed display for desktop measurement/analysis system
        • Application: Small electrical systems monitor (Solar electrical system)
        • Additional notes:
          • Deterministic timing in RTOS systems
            • Memory locking
            • Process scheduling
            • Garbage collection in the Common Lisp implementation
            • Kernel architectures (onto Linux kernel space)
            • See also: Realtime applications of Java / Realtime JVM implementations
      • Extensions in development of another mathematics platform in Common Lisp
        • Polar coordinate graphing *
        • Graphing for objects on Euclidean and Complex planes *
        • Measurement Units (See also: Igneous-Math)
        • Phasor diagrams *
          • EE Applications (AC systems; signals synthesis; signals analysis)
          • Applications in classical mechanics
        • Linear algebra *
          • Trivial concept: Presentation type for a matrix view of Common Lisp arrays
          • Less than trivial concept: Differential analysis, with corresponding presentation types
      • Extensions for systems modeling and interactive model design, in Common Lisp
        • URIs
        • XSD
        • XMI
        • UML Primitive types)
        • MOF
        • UML metamodel
        • SysML metamodel
        • ODM metamodels (RDF, OWL, Common Logic)
      • Extensions for a CORBA-centric desktop application framework
        • ORB monitor
        • IDL designer (IDE)
        • ??? (TBD)
* See also; Scigraph application, as published in McCLIM (referencing the MCi fork)

Certainly, the development of the fork is focused mostly towards usage cases. Beyond the maintenance updates, there may not be much to add to the McCLIM codebase itself.

Perhaps there may be an opportunity for adding some developer documentation to the codebase, over subsequent changesets in the codebase -- pending development of a suitably comfortable documentation system, perhaps extending of DocBook XML

This, then, would represent the first significant "Note to public" regarding the McCLIM fork developed under MetaCommunity.info.

Thus far, the fork is representative of the source tree cloned from Timothy Moore's original McCLIM source tree, with some changes merged in from Andreas Fuchs' fork, as was developed onto the original McCLIM CVS repository. I've also made a small number of maintenance updates to the source tree, including a short effort for a portable multiple-value setq (needs testing), and a defconstant* form to avoid errors on repeated redefinition of constant values.

Subsequently, the fork may also merge the changes developed under Robert Strandh's McCLIM fork. I'll make a note of that in my own Diigo bookmarks, and here.

This effort is, at the outset, mostly an academic matter. I cannot imagine any immediate commercial applicability about such work. Perhaps it might seem, then, as though it could represent something of a quixotic kind of "lark", in the conformity-oriented social network of "the modern." Regardless, there is the source tree as updated, to-date.
