This chapter continues from where Creating the workspace definition left us.
Defining targets in bash

@Override
public List<? extends Target> targets(TargetDefinitionContext ctx) {
return Arrays.asList(new HelloTarget("hello", "hello from iwant\n"));
List<Target> t = new ArrayList<>();
t.addAll(TargetImplementedInBash.instancesFromDefaultIndexSh(ctx));
return t;
}
@Override
public List<? extends SideEffect> sideEffects(
SideEffectDefinitionContext ctx) {
return Arrays.asList(EclipseSettings.with().name("eclipse-settings")

Let's see where we need to define the index.
~/iwant-tutorial $ as-iwant-tutorial-developer/with/bash/iwant/list-of/targets
(0/1 S~ org.fluentjava.iwant.api.javamodules.JavaClasses iwant-tutorial-wsdef-main-classes)
Please define targets in /home/hacker/iwant-tutorial/as-iwant-tutorial-developer/i-have/wsdef/src/main/bash/_index.sh
We create an index with one target.
~/iwant-tutorial $ mkdir as-iwant-tutorial-developer/i-have/wsdef/src/main/bash
~/iwant-tutorial $ $EDITOR "as-iwant-tutorial-developer/i-have/wsdef/src/main/bash/_index.sh"
targets() {
target hello-from-bash
}
We define the target in a script named after the target name.
~/iwant-tutorial $ $EDITOR "as-iwant-tutorial-developer/i-have/wsdef/src/main/bash/hello-from-bash.sh"
path() {
echo "Hello from bash" > "$IWANT_DEST"
}
Now we can evaluate our first target defined in bash.
