Forum: Instiki – Topic: noob backup question

If you’re using the (default) sqlite3 database, that’s a plain file in the db/ directory. Just copy it over to the new installation. If you’ve uploaded files to your wiki, they’re in the webs/ directory. Again, just copy them over to the new installation.

Forum: Instiki – Topic: tex2svg on Heroku

If you’re using the “free” level of service at Heroku, then timeouts can be a problem. It takes a while for Heroku to spin up a Dyno. Just try editing the page again. Once tex2svg is up and running, it should respond very quickly.

As to setup, there are many ways to do it. The simplest is simply to have two Heroku apps that talk to each other over http(s). So, e.g., in Instiki’s config/environments/production.rb, you could have

ENV['tikz_server'] = 'https://some-name-for-tex2svg.herokuapp.com'

This configuration can suffer from the timeout issue just mentioned.

Better would be to have them both running in the same Heroku instance. But that’s a Heroku question, not an Instiki question and you’ll get better advice on one of the Heroku forums.

You will need to upgrade to the latest Instiki if you want to run on Ruby 2.7.

The Instiki website is running on Ruby 2.7.1.

Forum: Instiki – Topic: How do I bulk-clear the Instiki cache

What is the cleanest / simplest / safest way to purge the entire cache?

At the commandline, do an

rm -R

of the appropriate directory. There isn’t a GUI tool to do it.

In addition, the old URL is present in files in the top-level folder “storage.”

Those can all be deleted.

Forum: Instiki – Topic: installation problems (mac osx lion)

Googling around, that sounds like an antiquated version of RubyGems. If so,

gem update --system

should fix it.

On the other hand, since you have JewelryBox, you could just use it to install Ruby 2.0 or 2.1 (both of which should work with the development version of Instiki), which come pre-installed with a more modern version of RubyGems.

I’m working on updating my branch of Maruku, to incorporate various improvements from trunk. In particular, there are improvements to the table code. So you should check it out…

Forum: Instiki – Topic: Debugging uninterruptible sleep

Attach gdb to the process and try to figure out where it’s stuck. It would be interesting to me if there was an Instiki-specific reason these processes were getting stuck.

But, so far, there’s no evidence for that.

Forum: Instiki – Topic: S5 vertical alignment

I don’t know of a totally robust way to do it. My CSS-fu is weak.

But

Test Vertical Alignment
------------------------

This is centered on the slide
{: style="margin-top:25%;text-align:center;}

is a pretty good approximation to what you want.

Forum: Instiki – Topic: Bugs

And another one, this time in how maruku parses its meta-data.

This was actually only a problem for IALs attached to <li> elements. Fixed in the latest Maruku.

(This commit gives the complete solution. Its predecessor was only a partial fix.)

(N.b.: Maruku is now unvendored, so a

ruby bundle update

will pull in the latest version from Github.)

I’m unable to run the inbuilt SVG editor on my computer (running Mac OS X, Lion).

Works fine for me under Lion. (I haven’t updated to Mountain Lion, so I can’t make any promises about that. But I’d be surprised if there were any OS dependence of this; it ought to be a function of the Javascript engine in your browser. Or perhaps I misunderstood: were you running the server on Lion, or just the client?)

Forum: itex2MML – Topic: weird math fonts

Perhaps you need to install the STIX fonts (see here for some slightly out-of-date, but still useful instructions).

I see those calligraphic letters all set in the same font. And, moreover $\mathbb{P}$ and $\mathbb{Q}$ are set upright (as, for that matter, are $𝔸$ and $𝕓$).

Alas, what you see is strongly-dependent on what fonts you have installed.

In more detail:

On my system, ℬ (U+212C) is available in STIXGeneral, Apple Symbols and Arial Unicode MS. But 𝒜 (U+1D49C) is only available in STIXGeneral. In current versions of Firefox, I believe the default value of font.mathfont-family is

MathJax_Main, STIXNonUnicode, STIXSizeOneSym, STIXSize1, STIXGeneral, Asana Math, Symbol,
   DejaVu Sans, Cambria Math

so the version in STIXGeneral is what I see.

Forum: itex2MML – Topic: Bugs

That’s a “feature”, not a bug.

As described here, $ab$ is a single token in itex (tranlated to <mi>ab</mi>); $a b$ are two tokens (translated to <mi>a</mi><mi>b</mi>). MathML is semantically-richer than (La)TeX, and this convention gives you the ability to enter multi-character tokens, which will be interpreted as such, when translated to MathML.

Forum: Instiki – Topic: How could I preview/undo changes?

Every page has a “History”, a “Diff” between successive Revisions, and the ability to Rollback to a prior Revision.

Instead of a Preview, successive edits, within 1/2 hour, by the same user, do not create a new Revision.

So save your work, as you go and you’ll be able to see your progress and still not lose anything (remember, with other wikis, changes which have been previewed, but not saved, will be lost).

Forum: Instiki – Topic: Instiki 0.19.4

Launchd doesn’t play well with RVM. There are workarounds, e.g. here.

Hmm. And does

return 'true'? What does

#  /usr/bin/env ruby -v

return?

Forum: itex2MML – Topic: itex and other languages

That’s cool. I’m sure other people would be interested in your PHP extension. So you should think of packaging it for distribution (Pear?).

Forum: Instiki – Topic: Feature Requests

You’ll note that another bug that I fixed, in the same commit, was Maruku’s section numbering (disabled by default; see vendor/plugins/maruku/lib/maruku/defaults.rb). Dunno whether that’s of interest.

Forum: Instiki – Topic: Feature Requests

Ah.

That is indeed a bug. Fixed (in Instiki and Heterotic Beast, too). Thanks.

Forum: Instiki – Topic: Feature Requests

The issue of needing ids to keep theorem numbers in step has been raised (again).

I’m not quite sure what the issue is.

So if I write

+-- {: .num_theorem}
###### Theorem
$X$ is nuclear and Banach if and only if it is finite dimensional
=--

your theorems still get numbered (correctly, I hope).

Since there’s no label, there’s no easy way to refer to this theorem, but maybe you don’t care. And if you do care, wouldn’t you want to avoid the fragility associated to an automatically-generated id (which will change if someone re-orders the theorems, adds a new one, or whatever)?

I must be misunderstanding…

Forum: Instiki – Topic: Feature Requests

That sounds like a request for macro-support in itex. For a variety of reasons, that’s unlikely to happen.

On the other hand, perhaps you have something else in mind …

Forum: Instiki – Topic: Bugs

Q: what do I need to do to get Instiki chosing a normal font size for my Web by default?

You might try setting the font-size on #Content. But I’m puzzled: is the font-size different from what you see on my Instiki site (which should be the same as the font-size here). Or are those also too large for your taste?

Forum: Instiki – Topic: Bugs

Hi, I’m trying out Instiki 0.19.3 on Mac OS X Snow Leopard and am running into an issue when publishing a Web. On each page (at the top) I get displayed: …

That’s a bug, which was fixed in Revision 770.

Grab a copy of the latest development version (or get it from my BZR repository or from Github).

Another issue: after installing a new version if Instiki I wanted to import the extisting content from the old installation.

You can copy over your old database, and then follow the upgrade instructions to update the schema to the latest version.

Forum: Heterotic Beast – Topic: redirecting bug ??

Evidently, the default mailer configuration isn’t working for you.

In the latest revision, I’ve made the configuration easier to customize (edit config/initializers/mail.rb). That should do it for you.

Forum: Heterotic Beast – Topic: redirecting bug ??

Right!

http://localhost:3000/

resolves to a “site” named “localhost”, which is what you created when you ran the bootstrap script (with the default responses).

Connecting to

http://127.0.0.1:3000/

gets you to a different site (“127.0.0.1”) which doesn’t exist.

Since you want the URL for your site to be

http://peppercode.net:3000

that’s what you have to input, when you run the bootstrap script.

Later, you could set up another site (by going to http://peppercode.net:3000/sites), say:

http://foo.peppercode.net:3000

(where foo.peppercode.net resolves to the same IP address as peppercode.net), and run both forum sites off the same HB installation. I’m running three different sites (each with multiple forums), off this one Heterotic Beast installation.
