I need to change a folder name in groovy. I try to rename the folder name, but no luck.
class Example {
static void main(String[] args) {
String a = "Hello";
def fine = "C://Users//senthiln-1//generated-project";
def d=new File(fine);
print d;
def newDir = "C://Users//senthiln-1//generated-project-new";
if (d.exists()){
print "ssss"
}
def s= d.renameTo(newDir);
print s;
// println(a.plus("\"));
//println(a.plus("World Again"));
}
}

Please find below my code. I am trying to iterate through files and in a directory and print out all the match to the regex: (&)(.+?\b)
however this doesn't seem to work (it returns an empty string). Where did I go wrong?
import groovy.io.FileType
class FileExample {
static void main(String[] args) {
def list = []
def dir = new File("*path to dir*")
dir.eachFileRecurse (FileType.FILES) { file ->
list << file.name;
def s= "${file.text}";
def w = s.toString();
w.readLines().grep(~/(&)(.+?\b)/)
}
}
}
I figured it out:
import groovy.io.FileType
class FileExample {
static void main(String[] args) {
def list = []
def dir = new File("/path/to/directory/containingfiles")
def p = []
dir.eachFileRecurse (FileType.FILES) {
file -> list << file.name
def s = file.text
def findtp = (s =~ /(&)(.+?\b)/)
findtp.each {
p.push(it[2])
// As I'm only interested in the second matched group
}
}
p.each {
println it
}
}
}
Now, all the matched strings are stored in the array p and can be printed/used elsewhere by p[0] etc.
w.readLines().grep(~/(&)(.+?\b)/) does not do any output, it gives you the matching lines as return value, so if you change it to println w.readLines().grep(~/(&)(.+?\b)/) or w.readLines().grep(~/(&)(.+?\b)/).each { println it }, you will get the matched lines printed on stdout.
Btw.
def s= "${file.text}";
def w = s.toString();
w.readLines()
is just a biiiig waste of time. It is exactly the same as file.text.readLines().
"${file.text}" is a GString that replaces the placeholders on evaluation, but as you have nothing but the file.text placeholder, this is the same as file.text as String or file.text.toString().
But as file.text actually is a String already, it is identical to file.text.
And even if you would need the GString because you have more than the placeholder in it, GString already has a readLines() method, so no need for using .toString() first, even if a GString would be necessary.
I want to test the following class:
public class DBSync {
public dbNotify( String path ) {
if (!path) {
return
}
def pathIndex = path.lastIndexOf(File.separator)
if (pathIndex > 0) {
def folder = path[0..pathIndex - 1]
def fileName = path[pathIndex + 1..path.length() - 1]
println "Syncing from directory $folder for filename $fileName"
if (fileName.contains(EXCLUDE_FILE_PATTERN)) {
println "Filename is $EXCLUDE_FILE_PATTERN skipping db write "
return
}
writeToDB(folder, fileName)
}
}
public writeToDB ( folder, file ) {
// inserting to database
}
}
The test class is:
public class TestDBSync {
#Test
public void test() {
def dbSyncContext = new MockFor(DBSync)
def file = "file.zip"
def folder = "data"
def path = folder + File.separator + file
def called = false
// Expect at least one call
mockDBSyncContext.demand.writeToDB(1..1) { String folderargs, String fileargs -> called = true }
mockDBSyncContext.demand.dbNodify(1..1) { String pathargs -> return }
// Obtaining a usuable mock instance
def mockDBSyncProxy = mockDBSyncContext.proxyInstance()
// Fake calling the method
mockDBSyncContext.use {
mockDBSyncProxy.dbNotify(path )
}
// Verify invoked at least once?
mockDBSyncContext.verify(mockDBSyncProxy)
}
}
The test is failing and I am getting the following error:
junit.framework.AssertionFailedError: No call to 'dbNotify' expected
at this point. Still 1 call(s) to 'writeToDB' expected.
I am trying to process .pas file. I generated lexers, parsers, visitors, listeners for grammar
Here is my custom visitor implementation
class GroovyPascalVisitor extends PascalBaseVisitor<ScriptSkeleton> {
private static final String PASCAL_SCRIPT_NAME = "PascalScript"
#Lazy ScriptSkeleton scriptSkeleton = new ScriptSkeleton()
#Override
public ScriptSkeleton visitProgramHeading(
PascalParser.ProgramHeadingContext ctx) {
log.info "Visiting program heading"
def scriptName = ctx.identifier().getText()?.trim()
if (!scriptName) {
scriptName = PASCAL_SCRIPT_NAME +
"${new Random().nextInt(1000)}"
}
scriptSkeleton.scriptName = scriptName
return scriptSkeleton
}
}
Here is the code in my script
def file = new ANTLRFileStream(pas)
def lexer = new PascalLexer(file)
def parser = new PascalParser(new CommonTokenStream(lexer))
tree = parser.program()
stringTree = tree.toStringTree(parser)
visitor = new GroovyPascalVisitor()
skeleton = visitor.visit(tree)
The .pas file content looks like this
program HelloWorld;
begin
writeln('Hello, World!');
end.
But when I run script - it does not println message from log and object scriptSkeleton is null, meaning that it does not invoke visitProgramHeading at all.
What it is the problem?
how do I print available environments from a config file? What is the form of the ojbect ConfigSlurper creates?
I tried
def config2 = new ConfigSlurper().parse(new File('obieeadmincfg.groovy').toURL())
config2.config.environments.each { println ${it} }
and
println prettyPrint(toJson(config2))
and
for ( i in 0 ..config2.config.environments.size()-1)
println config2.config.environments[i]
groovy.config
//Config3.groovy
obieadmin {
//default values
serverurl = "http://default.mycompany.com"
}
environments {
pldev01 {
obieeadmin {
serverurl = 'devgdwobi03.x.com'
}
}
plsbx02 {
obieeadmin {
serverurl = 'devgdwobi03.x.com'
}
}
}
I'm afraid you can't do this out-of box.
But using a bit of Groovy Metaprogramming it's achievable.
Groovy config slurper parses proper Groovy file, and you can do the same with GroovyShell. You can catch call to environment method providing closure in binding. In that closure you have to collect all top-level method calls(with same methodMissing).
Providing base script with property and method missing handlers, you can suppress runtime errors, and execute script without much care to other properties.
Not the nicest path, but it works.
package test
import org.codehaus.groovy.control.CompilerConfiguration
class A extends Script {
def propertyMissing(String name) { null }
def propertyMissing(String name, def arg) {}
def methodMissing(String name, def args) {}
#Override Object run() { null }
}
class NameCollector {
def envs = []
def methodMissing(String name, def args) { envs << name }
}
// configure interceptors.
def configuration = new CompilerConfiguration()
configuration.scriptBaseClass = 'test.A'
def nc = new NameCollector()
def environments = { Closure it ->
it.delegate = nc;
it.resolveStrategy = Closure.DELEGATE_ONLY
it()
}
// execute config script
new GroovyShell([environments: environments] as Binding, configuration).evaluate(new File("config.groovy"))
nc.envs // Return, print them.
Not sure if this is going to work forever but currently you can do it by overriding the setting for the 'environments' conditional block, like this:
def config = """environments {
dev {
foo = "bar"
}
prod {
foo = "baz"
}
}"""
def configSlurper = new ConfigSlurper()
configSlurper.registerConditionalBlock('environments', null)
assert configSlurper.parse(config).environments.keySet() == ['dev', 'prod'].toSet()
I just want to print files which are not located in ss
def folder = "./test-data"
// println "reading files from directory '$folder'"
def basedir = new File(folder)
basedir.traverse {
if (it.isFile()) {
def rec = it
// println it
def ss = rec.toString().substring(12)
if(!allRecords contains(ss)) {
println ss
}
}
Your question isn't exactly clear, but it looks like you're just trying to do
if (!allRecords.contains(ss)) {
println ss
}
in the last part of your code segment.
