Re: [Dltk-dev] IScriptBuilder/IBuildParticipant questions
|
Dependency tracking is supposed to be internal to the IValidator implementation - the method is called with the list of source modules (either manually right clicked by the user or changed before the build operation).
If it was passed A and validator knows that B depends on A - just validate B too.
The hard part here is actually tracking dependencies - execute perl several times is quite easier.
IScriptBuilder interface supports dependency tracking and IValidator could be extended to support it too, but I don't see the benefit - external validation is quite independent so there is no gain if additional modules would be added externally to the IValidator or internally in it.

Subject: Re: [Dltk-dev] IScriptBuilder/IBuildParticipant questions
i have another question :)
how can i track dependencies for 'perl -c' output using the IValidator interface?
for example:
- module A has compile error
- module B uses module A
- module A gets fixed
- module B should be recompiled again as it is a dependent of module A

thanks for the explanation alex. i'll take a look and i'm sure i'll be back w/ additional questions.

Jae,
I did not mention explicitly the interfaces of the 3rd part - IValidatorType/IValidator/ISourceModuleValidator - the API to call external process to perform some code checks/validation.
So there are 3 parts of the builder API in the DLTK:
- IScriptBuilder is the general API
- IBuildParticipant is the API to implement code checks in java code
- IValidator is the API to call external validation process
At the moment there are 2 implementations of the IValidator API:
A) Tcl checker
- org.eclipse.dltk.tcl.internal.tclchecker.TclCheckerType is a factory
- org.eclipse.dltk.tcl.internal.tclchecker.TclCheckerImpl is a configured instance
- org.eclipse.dltk.tcl.internal.tclchecker.TclChecker is a runtime instance
B) External Checker
- org.eclipse.dltk.validators.internal.externalchecker.core.ExternalCheckerType is a factory
- org.eclipse.dltk.validators.internal.externalchecker.core.ExternalChecker is a configured instance
- org.eclipse.dltk.validators.internal.externalchecker.core.ExternalCheckerWorker is a runtime instance
External validators are configured in the Preferences - DLTK - Validators
The list have checkboxes for each validator. If the checkbox is active - the validator is started automatically from the ValidatorBuilder (it implements IScriptBuilder). The checkbox is there since executing external process is time consuming operation, so the end user is able to enable/disable it.
Also they could be executed manually using popup menus:
- on the model element in the script explorer
- in the script editor
(the command in the popup menu is shown only if there are available validators)
The 'perl -c' is the ideal use case for the IValidator API. You just don't need to configure the path of executable and use the interpreter instead.
Today I am going to do refactoring of IBuildParticipant and move it to the dltk.core plugin. After that I will document all builders API in the Wiki.
Regards,
Alex

ahh - i was wondering why the 'add' button was grey-ed out on that page.
that mechanism isn't going to work for invoking 'perl -c'. the code needs to be compiled using whatever interpreter is configured for the project.
now that i understand the difference between the IScriptBuilder and IBuildParticipant extensions, i'll start putting together an IScriptBuilder implementation for this. i'll try to come up w/ something generic so ruby and other languages can leverage it as well.
thx!

One can use external checker without programming - it is developed

Preferences - DLTK - Validators - [Add] and so on.

i'm confused by what you mean about first testing it and then
building a
perl specific implementation.
