Subject: [opentheory-users] interpretation in separate file
Message-ID: <CAMej=27xn=h+eAwVi4nu6UwAgh1-haPiu1v=V5=JXhm5squaWw@mail.gmail.com>

Is it possible to include an interpretation in a theory file, rather than
having to write it out inline? Since I sometimes want to include a rather
large interpretation within multiple blocks within the same theory file, I
end up having to write a template file and then generate the real .thy file
from that, to avoid lots of copy-pasting. Is mine the recommended approach,
or is there a better way?

Hi Ramana,

I agree with you that it would be good for theory files to support
pulling in interpretations from files. How about the following syntax:

interpret-file: "file.int"

inside a theory block? It probably makes sense to allow multiple of
these, just like multiple

interpret: type/const "X" as "Y"

lines are allowed, but raise an error if the same symbol is
interpreted in multiple ways.

Cheers,

Joe

Hi Joe,

It turns out this is not so urgent for me since Michael and I came up with
another method:
Put all the article-combination stuff into one file uninterpreted.thy (main
block is a union), then turn that into uninterpreted.art, and finally do
the interpretation all at once (so it only appears in one file) in
interpreted.thy, whose main block is an article block for
"uninterpreted.art".

However, interpretations from files would probably still be good for other
scenarios. I would tweak your suggested syntax to use "interpretation"
rather than "interpret-file", to match "article" (which also takes a
filename).

Cheers,
Ramana

Hi Joe,

I have not had time to investigate this thoroughly yet, but I have a
suspicion that the redundant import check might not check for constants
that don't appear in any theorems. Therefore, removing a "redundant" import
might result in two different constants with the same name. Do you think
this is possible?

Cheers,

Hi Ramana,

That doesn't look good, but I think perhaps I'm the only one who's
uploaded packages up until now, so perhaps it shouldn't be too
surprising there are bugs lurking.

Here are some questions to help debug the problem:

Was there any output between executing the opentheory upload command
and the text you pasted?

What OS are you running?

Can you verify that you get this response from this curl command:

$ curl --silent --show-error --user-agent opentheory
http://opentheory.gilith.com/
gilith repo: welcome

What is the output of curl --version?

Cheers,

Joe

Actually I think I've uploaded a package before (called cl), but it was a
long time ago.

Hi Ramana,

There are a couple of different redundant warnings the tool can
generate: I assume your question is about the "redundant import X in
theory block Y" warning message, not the "redundant requires: X"
warning.

I've just looked at the code, and for an import X to be reported as
redundant in theory block Y both of the following must hold:

1. The theorems of X and the assumptions of Y are disjoint.
2. The defined symbols in the theorems of X and the input symbols in
theorems of Y are disjoint.

If I interpret your question correctly, you are concerned about
removing a redundant import X containing a defined symbol S that is
used in Y but not exported in a theorem. After scratching my head for
some time I cannot see how removing X from the imports of Y could
result in the creation of different symbols with the same name, but
perhaps I am missing something.

Do you have a problem scenario in mind?

Cheers,

Joe

Hi Ramana,

Well I can't see anything immediately wrong with your setup, and my
server logs are also uninformative.

Let me see whether I can still upload packages myself or if some
important bits have rotted.

Cheers,

Joe

Hi Joe,

Thanks for the clarification. I think you interpreted my question correctly.
After reading your description, I think the checks for redundant imports in
a theory block are correct as is.

In general, though, I note that it is effectively impossible to define a
constant in OpenTheory without also proving a theorem about it.
To get around this, I prove a trivial theorem (|- c = c) about a new
constant c to ensure its definition is picked up.

My original question was motivated by a problem that I still have. Namely,
I receive unexpected warnings about 2 different constants with the same
name. I thought this was because I hadn't imported the block that defines
the constant into all the blocks that use it, but (hopefully I checked this
right) if I add any of those import lines they are flagged as redundant.
The warning about different constants therefore looks like a red herring;
the resulting theory package doesn't appear to have any problems like
unexpected axioms or assumptions or ungrounded constants.

Perhaps you could explain further the circumstances under which the 2
different constants warning occurs. I can also provide the relevant
articles and theory packages but they are quite large and unwieldy so I'd
rather hold off on that at first.

Cheers,
Ramana
