  1. Pan CompilerStatus and Roadmap C. Loomis (CNRS/LAL) 14thQuattor Workshop (Ghent) 29-31 October 2012

  2. V9.2—Current Version • Features: • plan for removal of escaping (deprecate xmldb, change tests to use pan xml, …) • expanded maven support (archetype, simple build) • JSON output format • skeleton for updated panc command in clojure Pan Compiler (C. Loomis)

  3. V9.3—Development Version • Changes: • Significant parts are now in clojure. • RFE: Generate multiple output formats • Bug: Timestamp check on all output files • Bug: Non-object templates accessible with value() • Bug: Java 1.7 interface change (tests, ant task) • Bug: Use bash explicitly for shell scripts • Bug: Catch invalid replace string exception • RFE: Allow negative values in range expressions • Annotation/compilation split into two commands • Change of options for panc command (ant, maven, …) Pan Compiler (C. Loomis)

  4. V9.3—Development Version • Not released yet! • Add new options to ant/maven tasks • Update documentation! Pan Compiler (C. Loomis)

  5. New Options… panc [options] [pan source files...] Usage: Switches Default Desc -------- ------- ---- --no-debug, --debug false enable all debugging --debug-ns-include ns regex to include debugging --debug-ns-exclude ns regex to exclude debugging --initial-data set root element (must be nlist) --include-path template lookup path --output-dir output directory --formats pan,dep generated output formats --java-opts options for JVM --max-iteration 10000 set max. no. of iterations --max-recursion 10 set max. depth of recursion --logging set logging types --log-file specify log file --warnings on off, on, fatal -v, --no-verbose, --verbose false show statistics and progress -h, --no-help, --help false print command help Pan Compiler (C. Loomis)

  6. V9 Series Roadmap • Streamlined, simplified code… • Limited changes to functionality • Better, broader support of ant, maven, CLI etc. • Rationalization of options, output formats • Gradual migration to clojure • CLI, template compilation, functions, output formats, … • Limited inclusion of other libraries (e.g. JSON) Pan Compiler (C. Loomis)

  7. Support • V8.2.x and previous releases • Unsupported, upgrade to V8.4.7 and then V9.x • V8.4.7 is last release of V8 series! • Frozen (6+ months): move to V9 ASAP. • V9 series • Current version: V9.2 stable. • Significant options changes that should be propagated to downstream tools for V9.3. Pan Compiler (C. Loomis)

  8. Discussion • Roadmap • Problems, feedback, etc. Pan Compiler (C. Loomis)
