JJTree and custom classes #16

Closed jponge closed 9 years ago

jponge commented 9 years ago

I find using the support for custom classes with JJTree difficult.

Based on the current layout of org.eclipse.golo, I tried making a rudimentary Gradle build.

My Gradle build contains:

plugins {
  id "ca.coglinc.javacc" version "2.2.0"
}

(...)

compileJavacc {
  include '**/*.java'
}

The .jjt file that I am using with Maven sits under src/main/jjtree. I now have moved it to its package namespace, thinking that perhaps this would help the plugin find my custom classes (they sit under src/main/java):

src/main/jjtree/
└── fr
    └── insalyon
        └── citi
            └── golo
                └── compiler
                    └── parser
                        └── Golo.jjt

This didn't work much better, so I moved the custom classes (a package actually) to src/main/javacc:

src/main/javacc
└── fr
    └── insalyon
        └── citi
            └── golo
                └── compiler

And then the build fails, because it tries copying a generated file to itself :smiley:

Ok, I think I got it, sorry, I'm not familiar with the use of JJTree. As of 2.2.1, I only added support for custom classes in the compileJavacc task. Will add this support for compileJjtree as well.

johnmartel commented 9 years ago

Is it possible for you to please provide a minimal .jjt file that produces a few .java files along with the .jj grammar file, so that I can use that in my acceptance tests?

johnmartel commented 9 years ago

You can use 2.2.2, which fixes your issue, here is the build file (just slightly different from yours):

plugins {
    id 'eclipse'
    id 'java'
    id 'maven'
    id 'ca.coglinc.javacc' version '2.2.2'
}

repositories {
  jcenter()
}

group = 'org.eclipse.golo'
version = '3.0.0-SNAPSHOT'

description = 'Golo Programming Language (Incubation)'

sourceCompatibility = 1.8
targetCompatibility = 1.8

eclipse {
    project {
        name = 'golo-lang'
    }
}

sourceSets {
    main {
        java {
            srcDir compileJjtree.outputDirectory
            srcDir compileJavacc.outputDirectory
        }
    }
}

eclipseClasspath.dependsOn("compileJavacc")

dependencies {

  compile group: 'org.ow2.asm', name: 'asm', version:'5.0.4'
  compile(group: 'com.googlecode.json-simple', name: 'json-simple', version:'1.1.1') {
    exclude(module: 'junit')
  }
  compile group: 'com.beust', name: 'jcommander', version:'1.48'
  compile group: 'com.github.rjeschke', name: 'txtmark', version:'0.13'

  testCompile group: 'org.ow2.asm', name: 'asm-util', version:'5.0.4'
  testCompile group: 'org.ow2.asm', name: 'asm-analysis', version:'5.0.4'
  testCompile group: 'org.hamcrest', name: 'hamcrest-all', version:'1.3'
  testCompile group: 'org.skyscreamer', name: 'jsonassert', version:'1.2.3'
  testCompile(group: 'org.testng', name: 'testng', version:'6.9.4') {
    exclude(module: 'junit')
  }
}

task wrapper(type: Wrapper) {
  gradleVersion = '2.5'
  description 'Generates the Gradle wrapper scripts'
}

You will notice that there is no compileJavacc configuration necessary, as your custom AST classes are in the Java source set.

You also need to put the .jjt file inside its package, as such:

src/main/jjtree/fr/insalyon/citi/golo/compiler/parser/Golo.jjt

:+1: many thanks @johnmartel :smiley:

jponge commented 9 years ago

Works like a charm.
