Hello 😊
I'm trying to use the combinator Pry parser library
(https://code.dlang.org/packages/pry/0.3.2), but, as I'll explain in the
rest of this message, it seems to be a bad version of the lib that dub
downloads me.
So, simply by adding pry as a dependency on a virgin project, and using
features that are present in the documentation and examples, dub
indicates that these features are non-existent. I have identified the
following combinators that were not recognized: `delimited`, `optional`,
`skipWs`, `slice`, `utfString` and also the `stk `atom. There may be
others.
Searching in the code and in the different versions, it seems that the
combinators I quoted are not part of the old versions (under 0.3.2), but
it is indeed this version that I included in the blank project...
Here is a simple example (by the way, the examples in the "example"
folder don't work for me either):
```d
import pry;
import std.stdio;
void main()
{
   alias S = SimpleStream!string;
   with(parsers!S)
   {
       auto p = delimited(range!('0', '9').rep, tk!',');
       auto s = "3,3,4".stream;
       string[] values;
       S.Error err;
       auto r = p.parse(s, values, err);
       writeln(r);
   }
}
```
With the following dub.sdl :
```sdl
name "test"
dependency "pry" version="~>0.3.2"
```
By building, I get:
```bash
$ dub build
pry 0.3.2: target for configuration "library" is up to date.
test ~master: building configuration "application"...
source\app.d(9,12): Error: undefined identifier delimited
```
What's wrong with all this? How come I'm using the "newest" version of
pry, but an older version of the library seems to be used instead?
Is there a problem with the way I use dub, or is the library too old (4
years old anyway)?
It just needs a tag. delimited (for example) added here:
https://github.com/DmitryOlshansky/pry-parser/commit/808d01c30b50a928f5795dab7e6c0a7a392899b0
May of 2017, Last tag was v0.3.2 on January 2017.
Just add an issue, ask Dmitry to release a new version.
