  1. OpenG – Projects and Community As presented by Jim Kring February 4, 2002

  2. OpenG Package Tools (OGPT) • http://ogpm.sourceforge.net/ • Integrated tools for: building, installing, uninstalling, verifying, querying, updating, developing, and maintaining LabVIEW software packages • Consists of a package installer (now) and several add-ons (future) OpenG User Group Meeting

  3. OGPT - Package Installer (OGPI) • Core Module of the OGPT’s • Builds Installs and Uninstalls Packages on Windows, Mac, Linux (LabVIEW Zip Tools - zlib) • Basic User Interfaces • Windows Explorer Shell extensions for *.ogp files OpenG User Group Meeting

  4. OGPT - Package Installer (OGPI) • Demonstration OpenG User Group Meeting

  5. OpenG Toolkit (OGTK) • http://opengtoolkit.sf.net/ • A collection of various packages of VIs, integrated into the palette and development environment • Distribution of *.ogp files OpenG User Group Meeting

  6. OGTK – Palette Pkg • A mechanism to dynamically populate the “default” palette with VIs and subpalettes • Allows the OGTK to be distributed as a collection of individual pkg’s OpenG User Group Meeting

  7. OGTK – Palette Pkg • Synchronize with Directory • Dynamic Palettes! • <OpenG.lib>\palette • Functions • Controls OpenG User Group Meeting

  8. OGTK - LabVIEW Data Tools • Tools for parsing LabVIEW data and type descriptors • Variant wrapper adds polymorphism • Makes next-generation of LabVIEW tools possible • Implements at run-time what LabVIEW does at edit-time OpenG User Group Meeting

  9. OGTK - LabVIEW Data Tools • Get/set data names • Enums • Clusters • Arrays • Low-level type descriptor tools • Additional objects OpenG User Group Meeting

  10. OGTK - LabVIEW Data Tools • Example - Update Cluster Elements OpenG User Group Meeting

  11. OGTK - Variant Config File VIs • Fully recursive flattening and unflattening of LabVIEW data to INI files. • First use-case of the LabVIEW Data Tools pkg. • Supports almost all “common” LabVIEW Data Types OpenG User Group Meeting

  12. OGTK - Variant Config File VIs Simple Example [Channel1] Active=FALSE Maximum=0.000000 Measure=Voltage Channel Name="" Array="<size(s)=3> 1.000000 2.000000 3.000000" [Channel2] Active=FALSE Maximum=0.000000 Measure=Voltage Channel Name="" error in (no error).status=FALSE error in (no error).code=0 error in (no error).source="" OpenG User Group Meeting

  13. OGTK - Variant Config File VIs Recursion Example [Channel1] Active=FALSE Maximum=0.000000 Measure=Voltage Channel Name="" Array="<size(s)=3> 1.000000 2.000000 3.000000" Array.<size(s)>=2 Array 0.Active=TRUE Array 0.Maximum=4.000000 Array 0.SubArray="<size(s)=3> 1.000000 2.000000 3.000000" Array 1.Active=FALSE Array 1.Maximum=-2.000000 Array 1.SubArray="<size(s)=3> 5.600000 9.000000 -10.400000" OpenG User Group Meeting

  14. OGTK – Zip Tools • Multi-platform support • Win32: lvzlib.dll • Mac: lvzlib.shlb • Linux: lvzlib.so • Provides the core packing/unpacking functionality for OpenG Package Files (*.ogp) used by OGPI OpenG User Group Meeting

  15. OGTK – Zip Tools (extras) • Implements string inflation/deflation • Implements MacBinary (on Mac) encode/decode for preserving resource fork during packing OpenG User Group Meeting

  16. OpenG App. Builder (OGAB) • http://ogab.sf.net • Programmatic App Builds • Building by double-clicking .bld file (Win) • Icons for .bld files • Right-Click .bld file to launch custom build settings dialog OpenG User Group Meeting

  17. OpenG App. Builder (OGAB) • Optional segregation of OpenG VIs into an external library with diagrams and front panels intact for LGPL compliance • Command line interface for batch file builds • Open a VI in the LabVIEW Run-Time environment, for testing an application before building an .exe. OpenG User Group Meeting

  18. OpenG App. Builder (OGAB) • Currently supports LV 6.0 on Windows • In the future will support all platforms and versions OpenG User Group Meeting

  19. Open Source Test Executive (OSTE) • Project Team has formed • Some Internal development and discussion has begun • No releases yet • Visit OpenG.org >> Projects >> OSTE for project homepage URL OpenG User Group Meeting

  20. LabXML – An XML toolkit for LV • http://labxml.sourceforge.net/ • Creating (with complete design freedom), loading and saving XML files. • Searching in XML-documents • Replacing, adding and deleting elements in XML documents. • Validating XML-files (also against schemas) • Translating XML to other formats (like HTML) by means of XSLT OpenG User Group Meeting

  21. LabVNC – A VNC Server for LV • Implements a VNC server for VI Panels • Visit OpenG.org >> Projects >> LabVNC for project homepage URL OpenG User Group Meeting

  22. LabSQL – An SQL toolkit for LV • use ADO and SQL in LabVIEW to communicate with databases • Visit OpenG.org >> Projects >> LabSQL for project homepage URL OpenG User Group Meeting

  23. LabPython Python toolkit for LV • http://labpython.sf.net • Load and run a python script dynamically and access variables • Run python scripts in a LabVIEW script node OpenG User Group Meeting

  24. LabPython – Python toolkit for LV • Script node uses LabVIEW’s script node plug-in interface • <LV>\resource\script\ • If dll’s in the .\resource\script folder conform to the plug-in specification, they may be used with the script node OpenG User Group Meeting

  25. LabPython – Python toolkit for LV OpenG User Group Meeting

  26. LabVIEW Development Tools (LDT) • OpenG.org >> Projects >> LabVIEW Development Tools • GOOP Class Renaming Tool • VIs in memory Tool • Project Template Instantiation Tool • “Fastloader” tool • No releases in the past year OpenG User Group Meeting

  27. LabUseful OpenG Projects • OpenG.org >> Projects >> … • Robust TCP/IP • Read and Create Path • Find Nearest Match Value in Array • Print to PDF OpenG User Group Meeting

  28. Many others… • Single VIs and Code Snippets • Auto Backup tool • LabTRIS – another Tetris clone • “Fastloader” tool • BLD File Maker to automate DLL creation .bld files from VI ConPanes • 3-Way Switches • Too many others to list OpenG User Group Meeting

  29. OpenG.org • Open Source LabVIEW Community Hub • Project Registration • Discussion and Support Forums • Whitepapers and Articles • User Groups OpenG User Group Meeting

  30. OpenG.org Project Registration • Project Description • Embed HTML • Link to Files • Embed Images • OpenG.org does not host your project files! OpenG User Group Meeting

  31. OpenG.org Forums • Various Forums • Projects • Discussion • Support • User Groups • Announcements *phpBB is an open source forum application - http://www.phpBB.com OpenG User Group Meeting

  32. OpenG.org Package Registry (future) • A database of package locations • OpenG Package Installer Plugin client would look to the registry for a listing of available packages • Packages could be both downloaded and installed by the client without any “browsing” by the user OpenG User Group Meeting

  33. Recap • Visit OpenG.org >> Projects to find info on a project • OpenG Package Tools will provide the infrastructure for packaging and distribution • OpenG Toolkit is a distribution of various packages • Let’s get everyone to distribute their packages as .ogp’s OpenG User Group Meeting
