Hi Glauco,

That's excellent news!

I had a quick try and saw some error messages. We can track that in the
GitHub project issues from here on.
I'm excited to get Yamma to work!

Hi Thierry,

You can absolutely try it. I'm now using it in place of mmj2.

I'm using it in linux VMs, but I expect it to work on Windows, too. I
don't have a Windows machine with node.js installed, to try it out.

If you have node.js installed, you should simply install it from the
VS Code marketplace (I hope; with linux it worked out of the box).

You open a .mmp , and it activates the extension (it takes a few
seconds to parse the main .mm file, see the progress notification on
the bottom left)

It works better with an additional .mms file, that's a model for "step
suggestions" (I'll explain it to the group, when I can).
At present, set.mms is a 33 MB text file. You can create it, launching
the script
/yamma/server/src/stepSuggestion/ModelBuilderScript.ts
it takes a couple of hours in my VM. I could probably make it
dramatically faster, building parsing trees directly from proofs,
rather than running the early parser on every formula of every step of
every proof.
If someone has a "place" to publish the model, I will send the
set.mms.zip file (5Mb size), so everybody can download it.
I should add a command to launch the model builder from within Yamma.

Full "step derivation" is available a couple of minutes after the .mm
is parsed (it is single step, but imho it is really powerful: it
infers any kind of statement I've tried, in any proof: even with ten
or more parameters, and in long proofs).

I hope you'll try it.

(DISCLAIMER: while writing formulas, now and then, there's some
slowdown because the language server is sending a superlong error
diagnostic for every character you type: I will leave this as a
"verbose" non default option, but a shorter diagnostic message should
fix it)

Please, let me know how it goes.

    Hi Glauco,

    I have again been away from Metamath for some time, but I see you
    have
    persevered in the development of Yamma. How far are you?
    Can now I simply install and use the VSCode extension from the VSCode
    Marketplace?

    Thanks,
