ParserGeneratorCC

Fork of JavaCC 7.0.3 because the original code base has poor quality and PRs were not really merged. The overall goal is to maintain compatibility to JavaCC but

• The code itself should be better maintainable
• The code itself should conform to best-practices
• Because this is NOT JavaCC the class names are similar, but the base package name changed from net.javacc to com.helger.pgcc
• The created code requires Java 1.5

See https://github.com/phax/ph-javacc-maven-plugin/ for a Maven plugin that uses this CC.

This fork is not really actively maintained, except some severe problems arise. I mainly use it to power my ph-css CSS parser.

  • Updated to ph-commons 10
  • Java non-modern style no longer creates constructors without a Charset. See issue #29 - thanks @sfuhrm
  • Improved the code of the jj_ntk_f method to be more efficient
• v1.1.3 - 2020-05-13
  • Allow final when catching exceptions - issue #24
  • Changed Automatic-Module-Name to com.helger.pgcc
  • Fixed internal buffer corruption in generated code - issue #26
• v1.1.2 - 2019-05-02
  • JavaCC grammar can parse Java 7 language features (JavaCC PR 71)
  • Backported a CPP output fix from JavaCC
  • Fixed an error in JavaCharStream.template if KEEP_LINE_COLUMN is turned off
• v1.1.1 - 2019-01-28
  • Fixed an error in Java modern template SimpleCharStream - thanks to @nbauma109
• v1.1.0 - 2018-10-25
  • Focus is on improving the quality and consistency of the template files - this may cause interoperability problem because names change etc.
  • This version assumes that the created code uses at least Java 1.5 - JDK versions below 1.5 are no longer supported!
  • The option STATIC was removed - it caused too many variations in the templates which decreases maintainability. STATIC is now always false!
  • Added new option OUTPUT_ENCODING to define the character set for the output files
  • If JDK version is at least 1.6 than java.nio.Charset encoding is used and not String encoding in generated Streams.
  • The Java templates were modified so that the interface methods start with a lowercase character (beginToken instead of BeginToken) - the created code may need to be adopted!
  • A masking issue for ' and \ characters was resolved (issue #20)
• v1.0.2 - 2018-01-08
  • Fixed an error in jump-patching that was originally only considered if legacy exception handling was enabled - now ParserGeneratorCC can create itself using itself!
• v1.0.1 - 2018-01-05
  • Initial release with expected output compatibility to JavaCC 7.0.3
  • The JavaCC option GENERATE_STRING_BUILDER was removed - it was never evaluated
  • The JavaCC option LEGACY_EXCEPTION_HANDLING was removed - that was too much 1990 ;) - see issue #7. This implies that the class TokenMgrError is no longer available!
  • The JavaCC option GENERATE_CHAINED_EXCEPTION was replaced with deduction from the Java version (≥ 1.4)
  • The JavaCC option GENERATE_GENERICS was replaced with deduction from the Java version (≥ 1.5)
  • The JavaCC option GENERATE_ANNOTATIONS was replaced with deduction from the Java version (≥ 1.5)
  • The main applications previously located in the root packaged were moved to package com.helger.pgcc.main
  • Minor improvements for Java output if JDK level is ≥ 1.7
  • https://github.com/phax/ph-javacc-maven-plugin/ starting from v4 will use this package instead of JavaCC.
  • No pure RuntimeException or Error classes are thrown inside the code
• v1.0.0 - 2018-01-05 - had a regression and was therefore never released binary
