I have created a custom dsl command chain using methods in a groovy scripts . I have a problem in accessing this command chain from another groovy file . Is there a way to achieve the functionality ?
I have tried using "evaluate" which is able to load the groovy file , but it is not able to execute the command chain. I have tried using Groovy shell class , but was not able to call the methods.
show = {
def cube_root= it
}
cube_root = { Math.cbrt(it) }
def please(action) {
[the: { what ->
[of: { n ->
def cube_root=action(what(n))
println cube_root;
}]
}]
}
please show the cube_root of 1000
Here I have a CubeRoot.groovy in which executing "please show the cube_root of 1000" produces the result as 10
I have another groovy file called "Main.groovy" . Is there a way to execute the above command chain directly in Main.groovy as "please show the cube_root of 1000" and get the desired output ?
Main.groovy
please show the cube_root of 1000
there is no include
operation in groovy/java
and you could use GroovyShell
if you could represent your "dsl" as closures then for example this should work:
//assume you could load the lang definition and expression from files
def cfg = new ConfigSlurper().parse( '''
show = {
def cube_root= it
}
cube_root = { Math.cbrt(it) }
please = {action->
[the: { what ->
[of: { n ->
def cube_root=action(what(n))
println cube_root;
}]
}]
}
''' )
new GroovyShell(cfg as Binding).evaluate(''' please show the cube_root of 1000 ''')
another way - use class loader
file Lang1.groovy
class Lang1{
static void init(Script s){
//let init script passed as parameter with variables
s.show = {
def cube_root= it
}
s.cube_root = { Math.cbrt(it) }
s.please = {action->
[the: { what ->
[of: { n ->
def cube_root=action(what(n))
println cube_root;
}]
}]
}
}
}
file Main.groovy
Lang1.init(this)
please show the cube_root of 1000
and run from command line: groovy Main.groovy
