Re: [Clops-users] default download

[Fintan F. <fi...@gm...>]

Myself and Mikolas noticed this before, but hadn't got around to fixing it.

I believe the problem for us is to do with the platform setting. At least
that is what we had narrowed it down to before. It seemed that the
sourceforge site was doing some sort of OS detection and attempting to offer
the right file - we got different results on different OSs. On 0.2.1 we had
the platform set to Java SE I think, and for 0.2 we had "platform
independent". I seem to remember it offered 0.2.1 for windows, but 0.2 for
linux and mac.

It all seems to be different now due to the SF revamp, so I'm not entirely
sure what's going on.

Right now when I visit the page (FF on mac) I do not see any default
download.

Re: [Clops-users] new signature of the parse method

[Fintan F. <fi...@gm...>]

The plan is to wrap it, but our initial pass at implementation was just to
use a plain list.

We discussed this on Friday and had already agreed such.

[Clops-users] new signature of the parse method

[Mikoláš J. <mik...@gm...>]

Fint and Radu has changed the parse method to return a list of errors
rather than a boolean (and only runtime exceptions are thrown).
I must say I'd have preferred a class wrapping the list:
  a) To get the previous code to compile I added isEmpty() which looks
unintuitive. isOK would look nicer.
  b) The standard toString of List is probably not desirable for
presenting to the user the aforementioned class could have some
printMe method, presenting the errors nicely.

[Clops-users] default download

[Radu G. <rad...@gm...>]

For me the default download appeared to be 0.2, not 0.2.1. I tried to
change it from ("Project Admin" -> "File Manager") and the default
download disappeared completely :( However, SourceForge seems to have
some trouble right now since it gives "error 500" from time to time
and it even displayed once a list of "news" that were clearly old.

So, I'm hoping it's just a temporary SF glitch. Please let me know
what default download do you see when you go to

[Clops-users] enum

[Radu G. <rad...@gm...>]

I changed clops to maintain the order of enum values. The syntax for
the property "choices" of the type "enum" (and of the type
"enum-list") is now:
  choices="string1|string2(VALUE1),string3(VALUE2)"
You are guaranteed that VALUE1.compareTo(VALUE2) < 0. This is nice to
have if you use an enum to represent verbosity levels.

The syntax used to be:
  choices="string1(VALUE1),string2(VALUE1),string3(VALUE2)"
or
  choices="string1(VALUE1),string3(VALUE2),string2(VALUE1)"

I added as a task the check that values are unique.

Let me know if you see any problems with this, or if you like a
different syntax.

It is true that we need this if we want to model svn's etc. behavior.

In general, I don't like the assymetricity of false and true (i.e.
user being able to set things to true, but not to false).

Another thing is that you can have similar interactions between
options of non-boolean values, e.g. the verbosity in gzip is 0..3. I
think there should be a general guideline/syntactic sugar that tells
you how to handle these things (boolean or not).

Global defaults would be useful, I think.(the properties resemble
command line options more and more :) ).

Don't we need allowarg=false to match how svn and gzip behave anyway?
Which reminds me that you were saying something about global defaults.

[Clops-users] mutual overriding

[Mikoláš J. <mik...@gm...>]

I was just looking at svn and gzip and both contain the same pattern,
(realized differently):
-- gzip
      quiet -> verbose:={0};
        verbose -> quiet:={false};
-- svn
    quiet { $(verbose?) } -> verbose := { false };
    verbose { $(quiet?) } -> quiet := { false };

Both of them are wrong as the triggering variable might be set to
false instead of true, so I guess it should be
   quiet { $(verbose?) && $(quiet) } -> verbose := { false };
or
   quiet { $(quiet) } -> verbose := { false };

Suggestions?

 I know we can do allowarg=false, but I don't like that solution that much.

[Clops-users] 0.2.2

[Radu G. <rad...@gm...>]

There seem to be enough changes for a new release. From the logs:
* license file
* removed unnecessary runtime classpath
* compile path fix
* don't crash if 'choices' isn't specified for enums
* nested enums are static
* better error message when -t is not given (hack)
* better handling of multiline descriptions (although I see
OptionStore still contains crap
* generation of ant task base class
* (simple) ant task for clops

It would be nice if we could schedule one day for
bugfixing/testing/releasing. Let me know if you have one free day in
the next week.

Re: [Clops-users] usage after parsing

[Mikoláš J. <mik...@gm...>]

Hi David,

   the docs are generated via Velocity templates. Velocity is an
apache project, very similar to the C preprocessor
(http://velocity.apache.org/). There are several predefined templates
in the templates directory but you can define any template you want
and pass it as an argument to clops.

  Personally, I'm not too happy about printing rules, I think we could
improve it but still it seems difficult.

I think the templates that are in the project should give you an idea
what you can do (start by all.vm, help.vm), but of course, if you have
any questions let us know.

Regards,
  mikolas

Re: [Clops-users] usage after parsing

[David W <di...@ho...>]

Yes, I can see both of your points. In any case, the recommended method
is reasonably clean and consolidated. I will be occupied for a while
with adding all the commands and options and the other cleanup that
needs to be done, but I figured I would ask another question looking
forward.

What are your thoughts or advice on generating
documentation or help. I haven't read in great detail about this yet,
so I don't know if there's much control over the documentation format.
At the least, our documentation person will create a user's guide for
the CLI. It would also be nice for the complete usage to be pretty
printed if help is specified on the command line or if there was an
error with an option. Is the generated documentation capable of this or
was it meant more functional--to make the CLOPS specification file more
readable?

I'd agree with Mikolas, but for slightly different reasons.

Extending
the option types, by providing your own custom option class is possible
but will take a reasonable amount of work, largely in sufficiently
understanding the mechanisms involved in order to do so. I wouldn't
advise it in this case.


Even if you were to create a custom class, it will not be more
succinct and barely more efficient than creating a simple method that
takes the created option enum type as an argument, and returns an
instance of the type that you want (the body of the method just being a
switch statement with each case creating and returning the appropriate
subclass type).


Hope this helps,

Re: [Clops-users] usage after parsing

Hi David,

  technically this is possible as you can extend the option types
yourself and the rules can contain any java code.

However, it's something that I'd discourage you from doing as the
CLOPS file was meant to be as Java-independent as possible and should
express only the logic of options, not the program. There's always a
blurry line between the program and option processing, so this is a
matter of personal opinion.

Re: [Clops-users] usage after parsing

[David W <di...@ho...>]

Fintan, thanks. I hadn't even looked at the fly rules and didn't
realize how powerful they could be. I tried out what you described and
that worked.

I don't suppose there would be a way to use fly
rules and virtual options to create a new instance of a user defined
object? With the method mentioned previously, I would just need to pass
an enum value to a factory if I needed to create objects of a specific
type. I was wondering if I could even bypass the creation of this
factory and have CLOPS return back a new object of the type that I need
(they would all be subclasses of a single base class). So basically, it
would be nice if I could define an arg with type "Command" and then be
able to return back "CMD1Command" and "CMD2Command" depending on which
command was set.

Hi David,

Thanks for the question. If I understand you correctly, what I would recommend is this:

-Create a "virtual option" (i.e. an option that is not reachable in the FORMAT:: section, but is defined in ARGS::) of type "enum".

e.g.
  ChosenCommand:{}:{enum}:[choices="CMD1,CMD2,CMD3"]

-Create some fly rules to set the ChosenCommand option when any of your commands are set. I'm not sure if you know about fly rules, but they are rules that can are triggered when a certain option is set. 

e.g.
  CMD1 {$(CMD1)} -> ChosenCommand := {"CMD1"};

There's quite a bit going on in that example, so I'll break it down. The first CMD1 indicates that it is a rule that should be fired when option CMD1 is set. The curly braces are used to delimit where you can write arbitrary Java code. In the first case the code must be a boolean expression. In the second case it is an expression that is of the correct type for the object we are assigning to, which in this case is a String for ChosenCommand.


You could read the whole rule as: If CMD1 is set then check if CMD1 is
true. If it is true set ChosenCommand to the value "CMD1".

The $(CMD1) inside the braces is a placeholder that is converted into code that gets the value for the CMD1 option. I'm assuming your commands are all boolean options? If they are booleans and you are not allowing the user to write CMD1=false (disallow by setting property allowarg="false" in the option definition), then you can omit the {$(CMD1)} as this will always be true. Thus:

  CMD1 -> ChosenCommand := {"CMD1"};

-In the code where you direct the program's execution by the option values, you can simply get the value of the option ChosenCommand. Note that if you use the enum option type, we automatically generate an enum with the choices you provided in the option's specification. The enum definition will appear in the generated OptionInterface, and will be the return type for the getChosenCommand() method.


I hope I've answered your question. If any of the above is not clear, or you want to know more, just ask.

Cheers,

Fintan

Re: [Clops-users] licensing for CLOPS

[Fintan F. <fi...@gm...>]

Just to clarify:

All clops library/tool code and documentation is under the MIT license.

The clops release also contains the antlr, velocity and some velocity
dependencies. Each of these is under a separate license. None of these
libraries are required at the time of using the generated code (just the
clops-runtime.jar), so there is obviously no need to include them in your
product.

So the terms of the MIT license is all you have to worry about.

We mistakenly didn't previously include the license text in our releases on
sourceforge. We've remedied that now.

By the way, we appreciate your questions and use of the tool, so if you have
any feedback big or small, please send it our way!

Cheers,

Re: [Clops-users] usage after parsing

[Fintan F. <fi...@gm...>]

Hi David,

Thanks for the question. If I understand you correctly, what I would
recommend is this:

-Create a "virtual option" (i.e. an option that is not reachable in the
FORMAT:: section, but is defined in ARGS::) of type "enum".
e.g.
  ChosenCommand:{}:{enum}:[choices="CMD1,CMD2,CMD3"]

-Create some fly rules to set the ChosenCommand option when any of your
commands are set. I'm not sure if you know about fly rules, but they are
rules that can are triggered when a certain option is set.
e.g.
  CMD1 {$(CMD1)} -> ChosenCommand := {"CMD1"};

There's quite a bit going on in that example, so I'll break it down. The
first CMD1 indicates that it is a rule that should be fired when option CMD1
is set. The curly braces are used to delimit where you can write arbitrary
Java code. In the first case the code must be a boolean expression. In the
second case it is an expression that is of the correct type for the object
we are assigning to, which in this case is a String for ChosenCommand.

You could read the whole rule as: If CMD1 is set then check if CMD1 is true.
If it is true set ChosenCommand to the value "CMD1".

The $(CMD1) inside the braces is a placeholder that is converted into code
that gets the value for the CMD1 option. I'm assuming your commands are all
boolean options? If they are booleans and you are not allowing the user to
write CMD1=false (disallow by setting property allowarg="false" in the
option definition), then you can omit the {$(CMD1)} as this will always be
true. Thus:
  CMD1 -> ChosenCommand := {"CMD1"};

-In the code where you direct the program's execution by the option values,
you can simply get the value of the option ChosenCommand. Note that if you
use the enum option type, we automatically generate an enum with the choices
you provided in the option's specification. The enum definition will appear
in the generated OptionInterface, and will be the return type for the
getChosenCommand() method.

I hope I've answered your question. If any of the above is not clear, or you
want to know more, just ask.

Cheers,

Fintan

[Clops-users] usage after parsing

[David W <di...@ho...>]

The main question that I have is what would be the most efficient way to dispatch on options?

The CLI that I'm working on basically consists of two levels of options--commands and options. The best analogy is something like Busybox, where there's a single binary (in this case jar file) that implements multiple commands, each with its own set of options (if any).

So to be more concrete, in the "ARGS" section of the CLOPS file, I have command1 through commandN defined. I can check for the presence of a single command via iscommandNSet(). I'm wondering if there's a more efficient way of dispatching or testing for the command instead of doing a massive if/else-if statement, perhaps with enums or something (the enum could be used to create a proper subclass corresponding to a specific command). I would almost be tempted to define an enum with the same command names, create the correct method name programmatically (prepend "is" and append "Set" to the enum value), and then iterate through the list of enums, calling the automatically-generated method for checking to return back the correct enum.

Basically, any pointers or suggestions at this point would be great. Normally I would ruminate on this for a bit, but I'm in a crunch situation and would appreciate some pointers. Thanks.

We haven't discussed it yet explicitly. But the whole project is MIT license
thus the only obligation for you is not to remove the license from the
source code (if there is any).

[Clops-users] licensing for CLOPS

[David W <di...@ho...>]

I did have one question about the licensing for CLOPS. I will check
again, but is there a file or a license notice that I need to add
somewhere if I plan to redistribute CLOPS runtime along with the CLI
I'm working on (it will be in a commercial product)?

Re: [Clops-users] error running 0.2 on Windows

[David W <di...@ho...>]

Thanks Julien and Fintan for looking at the problem, responding to my email, and fixing the problem so quickly. I just downloaded the new point release and it works in Windows now as well.

I will definitely let you know if I have any other requests or see any other issues as I will be using CLOPS along with a coworker to rework a CLI that was written in Java and needs to be redone.

There was one issue that I posted on the sourceforge page, which was to update the examples directories (the build.xml as well as the lib directory) to work with the latest version of CLOPS. When I was going through the tutorial and trying to compile the wc example for myself, I had no clue what was going on until I looked into the jar files and then realized that the manifest had the previous version of velocity mentioned.

Hi David,

Firstly, thanks for your interest in clops and for reporting this issue.

I have been able to recreate this issue on windows xp x64, running java 1.6.0_13.

The issue was that we had a path containing a '/' instead of a File.separator, and we've now fixed this. It now works on my windows test setup. We have a created a maintenance release (0.2.1) which contains this fix.


https://sourceforge.net/project/showfiles.php?group_id=257014&package_id=315070&release_id=679186


If you can confirm that this fixed version works for you, that would be great.

Thanks again,

Fintan
