Feature request for Graham's scripts

The scripts at x31eq.com/temper are so damn useful, but there's one thing I find myself wanting to do that there's no option for. I'd like to be able to search for subgroup temperaments tempering out a given unison vector. For example, I want to be able to put in 121/120 and have it spit out all the 2.3.5.11 temperaments that temper that out, but ignoring the prime 7.

I agree, I have the same issue when I am looking for a 2.3.7.11.13 temperament using a specific comma. The first few it shows have good approximations to 5, but I could care less about 5. I just want it to optimize the primes other than 5.

It's something I've thought about but it generally makes a
mess of the interface. Firstly, there has to be a box to
enter the limit where currently there isn't. There still
has to be a way of assuming a default if the user doesn't
enter anything. Then, the script has to check that the
prime limit is valid for the commas entered, and produce a
readable error if it isn't. And it has to work out what
other limits can be given as options.

Note that the Python modules I used to implement it can
handle other limits, and you can download them and run them
in an interpreter. If you want to improve the CGI I can
send you the source code for that. The unison vector page
is about 130 lines.

Hm...

Put your commas in this box:
<form action="/cgi-bin/uv.cgi" method="post">
<div>
<textarea name="uvs" rows="10"></textarea>
</div>
<div>
<input type="text" name="limit">limit</input>
</div>

<input type="submit" value="Submit" />
</form>

:)

If the user doesn't enter anything, you could always just have it
default to the full-limit corresponding to the highest prime of any
comma entered, just like they do now.

I can think of some clever ways to do this, but I've been assuming
that you or Gene know some standard, canonical method to figure out if
an element belongs to a group...

You could either just have it crash with "invalid limit," and/or then
have it default to the full limit corresponding to the highest prime
entered in any one of the commas.

Just a few suggestions. You said before that you didn't have the time
to do it, but if it's more just a matter of logistics, maybe you'd
find the above suggestions helpful.

I might if I knew what you meant.
