When this becomes stable, I can add a link to your version on each theorem
page of the main site, like the link that now says "Structured version" for
Thierry's pages. This will let you have direct control over your content.
(To start with, your base URL would be hard-coded in metamath.exe, but
later I can add a keyword to the $t statement in set.mm so the URL can be
maintained there.)
I don't know your long term plans, but I'll mention that personally
(although I may be in the minority) I don't mind the ASCII notation in the
proofs. It shows a beginner the direct relationship to the set.mm source
and allows easy copy/paste. The user can also see the direct relationship
between the ASCII and the Unicode rendering by switching between your page
and the standard page, without having to consult set.mm or the awkward
"ASCII Symbol Equivalents" page.
BTW although of course it's not as convenient as your pages, some people
might not know that metamath.exe can show the substitutions made in a step:
MM> show proof 2p2e4 /detailed_step 18
Proof step 18: eqtr4i.1=oveq2i $p |- ( 2 + 2 ) = ( 2 + ( 1 + 1 ) )
This step assigns source "oveq2i" ($p) to target "eqtr4i.1" ($e). The
source
assertion requires the hypotheses "cA" ($f, step 13), "cB" ($f, step 14),
"cC"
($f, step 15), "cF" ($f, step 16), and "oveq1i.1" ($e, step 17). The parent
assertion of the target hypothesis is "eqtr4i" ($p, step 47).
The source assertion before substitution was:
oveq2i $p |- ( C F A ) = ( C F B )
The following substitutions were made to the source assertion:
Variable Substituted with
C 2
F +
A 2
B ( 1 + 1 )
The target hypothesis before substitution was:
eqtr4i.1 $e |- A = B
The following substitutions were made to the target hypothesis:
Variable Substituted with
A ( 2 + 2 )
B ( 2 + ( 1 + 1 ) )
