Custom Parser Examples
Examples of configuring the parser for specific use cases and performance optimization.
Performance Optimization
Fast Dependency Extraction
go
package main
import (
"fmt"
"log"
"github.com/scagogogo/gradle-parser/pkg/parser"
)
func main() {
// Create optimized parser for dependency extraction only
fastParser := parser.NewParser().
WithSkipComments(true). // Skip comments
WithCollectRawContent(false). // Don't store raw content
WithParsePlugins(false). // Skip plugins
WithParseRepositories(false). // Skip repositories
WithParseTasks(false) // Skip tasks
result, err := fastParser.ParseFile("build.gradle")
if err != nil {
log.Fatal(err)
}
// Only dependencies are parsed
dependencies := result.Project.Dependencies
fmt.Printf("Found %d dependencies in optimized parse\n", len(dependencies))
for _, dep := range dependencies {
fmt.Printf(" %s:%s:%s (%s)\n",
dep.Group, dep.Name, dep.Version, dep.Scope)
}
}Custom Configuration
Memory-Optimized Parser
go
package main
import (
"fmt"
"log"
"github.com/scagogogo/gradle-parser/pkg/parser"
)
func main() {
// Memory-efficient configuration
memoryParser := parser.NewParser().
WithCollectRawContent(false). // Don't store raw content
WithSkipComments(true). // Skip comments
WithParseTasks(false) // Skip tasks if not needed
result, err := memoryParser.ParseFile("build.gradle")
if err != nil {
log.Fatal(err)
}
project := result.Project
fmt.Printf("Memory-optimized parse completed:\n")
fmt.Printf(" Dependencies: %d\n", len(project.Dependencies))
fmt.Printf(" Plugins: %d\n", len(project.Plugins))
fmt.Printf(" Repositories: %d\n", len(project.Repositories))
}
