Our parser puts everything in terms of HPPL.hpplterm but for some reason all of a sudden its giving us a warning when we call "parser_main lexer_main lexbuf" - its expecting a unit type? This then leads to an error where we have a function that expects hpplterm but its receiving this supposed unit. http://i.imgur.com/TNjzPk0.pnghttp://pastebin.com

<lyxia>
parse_input ends with a while loop which has type unit
<lyxia>
uh parseInput
<lyxia>
parseProgram too
<adnotamentum>
It ends with the line "with Inputlexer.Eof -> quit_loop := false ; HPLanguage([])" so ends with type HPLanguage([]) which is an hpplTerm?
wtetzner has quit [Remote host closed the connection]
<lyxia>
No, that's inside the while loop, which discards that value
<adnotamentum>
Ahh ok, thanks. How would one return "parser_input lexer_input lexbuf"?
<lyxia>
store it in a ref
<lyxia>
or write a recursive function instead of a while loop

Hello, all. I'm trying to pin a PPX package for development purposes. I used to just write "opam pin add <package-name> ." to pin and install the package. Today, I rebuilt my ~/.opam directory (big version dependency mess) but now, with a fresh ~/.opam, the pinned package isn't showing up in ocamlfind. It shows up in opam list, but not ocamlfind list. Any suggestions on how to start?

<tvynr>
I've run "opam install <package-name>" and the package is installed: "opam list" shows the package. But "ocamlfind list" does not. :(

<octachron>
tvynr, have you checked that ocamlfind is the right one?
<tvynr>
octachron: Yep. They're all running out of the same directory. I think I may have discovered my problem. Is this channel logged somewhere? Will it help people if I describe the scenario here?
tautologico has quit [Quit: Connection closed for inactivity]
<tvynr>
So for the record: I'm developing a PPX library. The reason it didn't show up in ocamlfind is because, although I had a META file installed with the package, the OASIS META plugin was handily stomping on my hand-written META file. The proper solution was to use the XMETAExtraLines option provided by the META plugin.
<tvynr>
I now have a different problem. I've pinned that package and I am developing another package which relies upon it. When I try to pin *that* package, I get "Sorry, no solution found: there seems to be a problem with your request." This is the only feedback I get (other than the usual "<package-name> needs to be installed" sort of progress) regardless of verbosity level.
<tvynr>
So my question is: is there a way to tell the solver to dump everything it's doing?
<Drup>
-vvvvv to opam will give you the exact formula
<Drup>
(don't remember the amount of v necessary, but you should find it :p)

I found an issue (https://github.com/ocaml/opam/issues/2717) that seems to be related, but I'm not sure how to verify that my version of opam has the problem. In either case, the newest-packaged version of opam for Debian seems to be the one I'm running: 1.2.2-5+b7. Is there an easy way to run a bleeding-edge OPAM temporarily?

I just built a copy of OPAM from the GitHub repository's master; it's an OPAM 2.0 beta. That version of OPAM seems to install the package happily. I wish I knew what I'd done to incite the problem, though, as this means I need to be using the 2.0 beta to develop these packages. :-/
<tvynr>
Thanks for the help, all.

octachron: This might explain why things are broken in 4.02.3. I'm unable to install cohttp=0.22.0 on a fresh OPAM 1.2 root using 4.02.3. I'm going to verify that it works for 4.04.0 and then try to proceed this way. That said, I'm working on projects that support 4.02.3, so not being able to publish from that switch is annoying. :-P Thanks for the heads up.

octachron: I tried doing some surgery on the _oasis file for cohttp to make it use the uchar package... but I had no luck.

In the BuildDepends of my _oasis file, I list "ppx_deriving.std" as a dependency of my library. But when I run oasis2opam, this turns into: "ppx_deriving" {= "1.0"}
<tvynr>
Any idea how I can figure out why that's happening?
<smondet[m]>
tvynr: "ppx_deriving.std" is part of the `ppx_deriving` package, so it makes sense
<tvynr>
Specifically, I'm trying to figure out why it's requiring version 1.0.
<tvynr>
(Sorry; I wasn't clear.)
<tvynr>
If it said >= "1.0", I'd probably be happy.
<tvynr>
Yeah. And so the generated dependency is weirdly conflicting with my other packages.
<smondet[m]>
you should just modify the `opam` file; I don't think `oasis2opam` is that smart...
<tvynr>
Kind of defeats the point of using oasis2opam if I do that. :( I'm going to poke around in oasis2opam and see if I can sort out where this nonsense is coming from. Thanks for the validation, though; it's nice to know I'm not missing something silly. :)
