Find parse to print inequality

org.openrewrite.search.FindParseToPrintInequality

OpenRewrite Parser implementations should produce SourceFile objects whose printAll() method should be byte-for-byte equivalent with the original source file. When this isn't true, recipes can still run on the SourceFile and even produce diffs, but the diffs would fail to apply as a patch to the original source file. Most Parser use Parser#requirePrintEqualsInput to produce a ParseError when they fail to produce a SourceFile that is print idempotent.

Usage

This recipe has no required configuration parameters and comes from a rewrite core library. It can be activated directly without adding any dependencies.

Gradle

1. Add the following to your build.gradle file:

build.gradle

plugins {
    id("org.openrewrite.rewrite") version("6.12.0")
}

rewrite {
    activeRecipe("org.openrewrite.search.FindParseToPrintInequality")
}

repositories {
    mavenCentral()
}

2. Run gradle rewriteRun to run the recipe.

Gradle init script

1. Create a file named init.gradle in the root of your project.

init.gradle

initscript {
    repositories {
        maven { url "https://plugins.gradle.org/m2" }
    }
    dependencies { classpath("org.openrewrite:plugin:latest.release") }
}
rootProject {
    plugins.apply(org.openrewrite.gradle.RewritePlugin)
    dependencies {
        rewrite("org.openrewrite:rewrite-java")
    }
    rewrite {
        activeRecipe("org.openrewrite.search.FindParseToPrintInequality")
    }
    afterEvaluate {
        if (repositories.isEmpty()) {
            repositories {
                mavenCentral()
            }
        }
    }
}

2. Run gradle --init-script init.gradle rewriteRun to run the recipe.

Maven POM

1. Add the following to your pom.xml file:

pom.xml
