MAVEN_DOT_PROJECT_REGEXP =

Matches digraph contents from the Maven dependency tree .dot file format.

/digraph\s+"([^"]+)"\s+{/
MAVEN_DOT_RELATIONSHIP_REGEXP = 
/"([^"]+)"\s+->\s+"([^"]+)"/
GRADLE_TYPE_REGEXP =

e.g. "annotationProcessor - Annotation processors and their dependencies for source set 'main'."

/^(\w+)/
GRADLE_DEP_REGEXP =

e.g. "| \--- com.google.guava:guava:23.5-jre (*)"

/(\+---|\\---){1}/
GRADLE_ARROW_REGEXP = 
/ -> /
GRADLE_PROJECT_REGEXP =

The name of the project containing the given dependencies

/\s*(Root p|P)roject '?(:?[^\s']+)'?/
GRADLE_DEPENDENCY_PROJECT_REGEXP =

Dependencies that are on-disk projects, eg: e.g. "--- project :api:my-internal-project" e.g. "+--- my-group:my-alias:1.2.3 -> project :client (*)"

/project (:?\S+)?/
GRADLE_LINE_ENDING_REGEXP =

line ending legend: (c) means a dependency constraint, (n) means not resolved, or () means resolved previously, e.g. org.springframework.boot:spring-boot-starter-web:2.1.0.M3 () e.g. the "(n)" in "+--- my-group:my-name:1.2.3 (n)"

/(\((c|n|\*)\))$/
GRADLE_DEPENDENCY_METHODS =

Builtin methods: https://docs.gradle.org/current/userguide/java_plugin.html#tab:configurations Deprecated methods: https://docs.gradle.org/current/userguide/upgrading_version_6.html#sec:configuration_removal

%w[api compile compileClasspath compileOnly compileOnlyApi implementation runtime runtimeClasspath runtimeOnly testCompile testCompileOnly testImplementation testRuntime testRuntimeOnly].freeze
GRADLE_VERSION_REGEXP =

Intentionally overly-simplified regexes to scrape deps from build.gradle (Groovy) and build.gradle.kts (Kotlin) files. To be truly useful bibliothecary would need full Groovy / Kotlin parsers that speaks Gradle, because the Groovy and Kotlin DSLs have many dynamic ways of declaring dependencies.

/[\w.-]+/
GRADLE_VAR_INTERPOLATION_REGEXP =

e.g. '$myVersion'

/\$\w+/
GRADLE_CODE_INTERPOLATION_REGEXP =

e.g. '$my-project-settings["version"]'

/\$\{.*\}/
GRADLE_GAV_REGEXP =

e.g. "group:artifactId:1.2.3"

/([\w.-]+):([\w.-]+)(?::(#{GRADLE_VERSION_REGEXP}|#{GRADLE_VAR_INTERPOLATION_REGEXP}|#{GRADLE_CODE_INTERPOLATION_REGEXP}))?/

SBT_TYPE_REGEXP =

e.g. "[info] test:"

e.g. "[info] org.typelevel:spire-util_2.12"

/^\[info\]\s+(.+)$/

/^\[info\]\s+-\s+(.+)$/
SBT_FIELD_REGEXP =

e.g. "[info] homepage: http://www.slf4j.org"

/^\[info\]\s+([^:]+):\s+(.+)$/
SBT_IGNORE_REGEXP =

e.g. "[info] "

/^\[info\]\s*$/
ANSI_MATCHER =
