Ant's current CVS version contains an <input> task that gathers user |
|
|
|
|
|
input by reading from System.in - this is not too nice for people |
|
|
|
|
|
embedding Ant in IDEs. 8-) |
|
|
|
|
|
|
|
|
The input proposal has been accepted as part of main Ant and has been |
|
|
|
|
|
merged with the main code tree on 2002-04-22. |
|
|
|
|
|
|
|
|
<input> also supports an undocumented testinput attribute that is used |
|
|
|
|
|
by Ant's test cases to allow them to run without user interaction, but |
|
|
|
|
|
could also be used to provide predefined answers to unattended builds. |
|
|
|
|
|
|
|
|
The only part that didn't get moved over was SwingInputHandler that |
|
|
|
|
|
has never been more than a proof of concept - if you really want to |
|
|
|
|
|
see it, you can find it in CVS's Attic: |
|
|
|
|
|
|
|
|
This proposal tries to define a very basic input framework for Ant |
|
|
|
|
|
that would allow Ant to be easily embedded into IDEs via |
|
|
|
|
|
implementations of the org.apache.tools.ant.input.InputHandler |
|
|
|
|
|
interface. At the same time an implementation of the interface is |
|
|
|
|
|
provided that allows the input to be specified via an external |
|
|
|
|
|
property file. |
|
|
|
|
|
|
|
|
|
|
|
There are three implementations of the InputHandler interface, |
|
|
|
|
|
DefaultInputHandler which reads form System.in just like the <input> |
|
|
|
|
|
task originally did, PropertyFileInputHandler for non-interactive |
|
|
|
|
|
builds and SwingInputHandler which is nothing more than a proof of |
|
|
|
|
|
concept. |
|
|
|
|
|
|
|
|
|
|
|
Input requests get encapsulated in instances of the |
|
|
|
|
|
org.apache.tools.ant.input.InputRequest class - or subclasses thereof |
|
|
|
|
|
- which provide a method to also validate the input, moving this |
|
|
|
|
|
responsibility from the <input> task to the InputRequest itself. |
|
|
|
|
|
|
|
|
|
|
|
There are two types of InputRequests ATM, InputRequest encapsulates a |
|
|
|
|
|
request for a simple unrestricted text input, |
|
|
|
|
|
MultipleChoiceInputRequest is a request where valid inputs are |
|
|
|
|
|
restricted to a given set of values. |
|
|
|
|
|
|
|
|
|
|
|
If you run ant on the build file in this directory, a version of |
|
|
|
|
|
ant.jar will be created in the build subdirectory that is identical to |
|
|
|
|
|
the main trunk of Ant except for the input task itself and two minor |
|
|
|
|
|
changes to Project and Main, that allow InputHandlers to be plugged in |
|
|
|
|
|
programmatically or via a commandline switch -inputhandler. |
|
|
|
|
|
|
|
|
|
|
|
With this version of Ant, run the input.xml build file in |
|
|
|
|
|
proposals/testcases, Ant should behave the same way the input task for |
|
|
|
|
|
the main branch does - except that it won't allow you to enter invalid |
|
|
|
|
|
input in the multi target. |
|
|
|
|
|
|
|
|
|
|
|
If you invoke Ant like this: |
|
|
|
|
|
|
|
|
|
|
|
ant -f proposal/sandbox/input/src/testcases/input.xml -inputhandler org.apache.tools.ant.input.SwingInputHandler |
|
|
|
|
|
|
|
|
|
|
|
You'll get the ugliest dialog you've ever seen, but it works ;-) |
|
|
|
|
|
|
|
|
|
|
|
Use |
|
|
|
|
|
|
|
|
|
|
|
ANT_OPTS=-Dant.input.properties=proposal/sandbox/input/src/testcases/works.properties\ |
|
|
|
|
|
ant -f proposal/sandbox/input/src/testcases/input.xml -inputhandler org.apache.tools.ant.input.PropertyFileInputHandler |
|
|
|
|
|
|
|
|
|
|
|
to see the non-interactive build process in action. fails.properties |
|
|
|
|
|
provides a sample of possible input failures. |
|
|
|
|
|
|
|
|
|
|
|
The original testcase for <input> has been ported to the new framework |
|
|
|
|
|
as well, run it via |
|
|
|
|
|
|
|
|
|
|
|
ant run-test |
|
|
|
|
|
|
|
|
|
|
|
in this directory. |
