May I suggest you give https://github.com/jawher/mow.cli a look/try ? Disclaimer: I'm the author of mow.cli ;)

Thanks for citing mow.cli [1] and glad you're liking it! And you are spot-on regarding closures: it was a design choice made expressly for the purpose of being able to: - scope command specific flag and args, instead of having one gian

docopt() does few things and does them well: * parse the call arguments and split them into options and arguments * perform a very basic validation, i.e. handle the options which take a value and those who don't Granted, mow.cli is muc

Parser combinators would certainly have been easier for me, the library author but not necessarily so for the end user. Contrast how it is done now: [-R [-H | -L | -P]] [-fi | -n] [-apvX] SRC... DST With a parser combinator based app

Is it just me or does anybody else think that polluting your code with debugging and logging informations is not such a good idea ? I understand the value of these informations, but changing your method signatures to take them is going too

Can't you take te same approach ClojureScript took, i.e. to generate a straitforward translation to JavaScript, and then let Google's closure compiler take care of the optimizing thing ? For instance, for this Roy generated JS: var Tr

While I share your enthusiasm, I'd like to point out some problems with "Sending rovers to all the planets": 4 of them are gaseous giants, literally no solid ground to land on. Venus is a no go too with its crushing atmospheric pressure, su

That depends on what kind of products you make: If it's a website, then you have absolute control over what stack and database to use. But if you're selling any kind of app that needs a database, then you'll need to support different databa

It's not just the SQL. There's also the mapping code between your objects and the SQL. for instance, for a select query: select first_name, last_name, login, email from users where id = 5; Depending on the language and ORM you use,

by jawher 15y ago
It depends on the ORM you use, but I'm afraid it's not as simple as "you can later hand write SQL queries to speed things up". This will interact badly with the ORM's cache/transaction handling: your select queries won't see uncommitted cha

The answer to your first question is yes, a lambda is always assigned to a SAM type. As to your second question, yes, you can cast a lambda to explicitly specify it's target SAM type: obj.method((Runnable)(()=> println("oh hai !")

Even Java has the Void type, meaning you can write: Function<Void> It's a bit shady though as you still have to return a value from the body of the method, and that value has to be null.

To the best of my understanding, lambdas-as-objects would mean providing structural types, i.e. generic function types that are able to describe the structure of a lambda (arguments and result type). e.g. (a fictive syntax): Function

There is also http://www.goodreads.com/ , a feature packed (maybe too much) and a generic (as in not tied to any reading app/device/mode) ... how shall I put it? reading management solution with a social flavour to it.

Genuine question: What does Sencha (a JS UI lib) have to do with Edge (an IDE) ?

by jawher 15y ago
I fail to see how the lambdas, when added, will make the language more complex. Here's an example: given a list of persons, we'd like to extract all the adults. Compare the good ol' way of doing things in Java: List<Person> persons

As I see it, the Model in MVC is everything that is not C or V. It encompasses the service layer, the DAOs, the data objects and what have you. The term Model on it's own doesn't mean much, and is very overloaded with meaning. You can see i

Yep, I was expecting something like: class Lorem(val ipsum: Dolor) extends Sit { def amet(consectetur: Adipisicing) : Elit = sed.do((eiusmod: tempor) => incididunt) }
