No activity on PR, and issue update, since Jan.

Sign, it works so nicely.

Hi,

Right now the arg's type is either string, or string[], and user need to convert manually to other types, e.g.

    int depth = args.arg("depth").to!int;

is it possible to allow user specify the arg type directly, e.g.

          .add(new IntArgument("depth", "dir depth"))

and access it directly later as:

    int depth = args.arg("depth");  // directly get int value

Thanks.

Using "-" as word separator in long option names has a long history, and options of many compilers contain long option names (eg --disable-loop-unrolling).

However this seems not to be allowed:

commandr.program.InvalidProgramException@/home/james/.dub/packages/commandr-0.2.0/commandr/source/commandr/program.d(49): invalid name 'min-length' passed

due to this:

Will simply adding another OR clause with "-" be sufficient or will somewhere else in the parsing logic blow up?

I was wondering if there is a possibility of having a Option that accept multiple space separated values or alternatively a function to specify how many parameters are needed by Option .
Example:

test --delete file1 file2 file3

One of my utilities does the following:

kpd -p 2
[ play song number 2 ]

kpd -p
[pause or resume playing]

At the moment commandr allows only Options (useful in the first case) and Flags (useful for second case).
Can a mixed Option/Flag be added? Or even better a Class that accepts all kind of inputs but requires a validator.

Hi,

First of all, thanks for great library. It is really awesome)

And, it would be nice, if you release new version that supports dashes in option names. I see that these changes are already on master, but there is no release with this functionality yet.

Thanks

I was just playing around with your library (cool work so far) and noticed that the version flag is not handled correctly. Code to reproduce:

import std.stdio;
import commandr;

void main(string[] args) {
    auto a = new Program("example", "3.14")
        .add(new Argument("foo", "a mandatory argument"))
        .parse(args);

    writeln(a.arg("foo"));
}

Expected output:

$ ./example --version
3.14

Actual output:

$ ./example --version
Error: missing required argument foo
example [-h] [--version] foo

I think already I have a solution for this and will open a PR after I tested it.

I tried the example code:

.validateEachWith(opt => opt.isDirectory), "must be a valid directory");

but it errors out:

Error: template commandr.validators.validateEachWith cannot deduce function from argument types !()(Option, void), candidates are:
.dub/packages/commandr-0.1.1/commandr/source/commandr/validators.d(458,10):        validateEachWith(T : IEntry)(T entry, void delegate(IEntry, string) validator)
.dub/packages/commandr-0.1.1/commandr/source/commandr/validators.d(488,10):        validateEachWith(T : IEntry)(T entry, bool delegate(string) validator, string errorMessage)

I changed to isDir or isFile:

https://dlang.org/library/std/file/is_dir.html
https://dlang.org/library/std/file/is_file.html

still doesn't work. Should the function be added in addition to delegate?

And can you add an example.d?

I want to use this to help me begin writing CLI applications in D but it seems as if the site for documentations just does not exist anymore?

Is there anywhere else I can find it?
Thank you
