Hmm. Yes, it looks like the Gemfile.lock.heroku was out-of-sync with the Gemfile.heroku. I’ve updated both of them.

Forum: tex2svg – Topic: Announcing tex2svg

Actually, with tex2svg 1.0.12, the size of the Docker image has shrunk to 1.09 GB.

Forum: tex2svg – Topic: Announcing tex2svg

With the aid of this optional add-on, Instiki (and this forum) can process embedded Tikz code to produce SVG figures. Think of it as a non-WYSIWYG alternative to SVG-Edit. You can get the code from Github.

The easiest way to run it is as a Docker container. The Docker image is 2.14 GB, which is on the large side, but not as large as a full Texlive installation. Instructions for integrating it with Instiki are here.

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: ubuntu upgrade broke instiki

Forum: Instiki – Topic: Using instiki.desktop to autostart at login

@distler I’m actually using the OpenRC init system, so the changes to most (would have to be close to 100% of) distros go beyond just those (the vast majority) that use systemd.

Again my apologies to readers for the mess that my instiki.desktop file presents as in the OP. You should be able to work out what it looks like by looking at a .desktop file in your own ~/.config/autostart/

Forum: Instiki – Topic: Using instiki.desktop to autostart at login

Definitely should update those instructions for systemd, which seems to have replaced init in most Linux distros.

Forum: Instiki – Topic: Using instiki.desktop to autostart at login

The formatting is messed up,

Path=

should be on its own line (I obviously haven’t yet learned markdown).

Forum: Instiki – Topic: Using instiki.desktop to autostart at login

I looked at the wiki page on autostarting instiki at login & it is somewhat out of date.

So I thought I’d see if I could kludge my way to an autostart by using a ~/.config/autostart/instiki.desktop file.

& it works fine. So it should be a simple autostart method for all Linux distros (I just run instiki on my local machine for personal use).

I’m sure that the following instiki.desktop file that I created could be improved & made more correct. But it works great as it is & instiki uses next to no resources when run in the background, which makes me happy.

So hopefully the following is useful to someone (be sure to change the path to that of where you have instiki installed on your system): ________________________________________

Forum: Instiki – Topic: Installation problem

Can you access

? If so, what are all the links on that page?

(Clearly, something got screwed up in creating your first wiki. If we can’t straighten this up, I’d suggest reinstalling.)

Edit: To be clear, a full reinstall is probably not necessary. A simple

kill <pid-of-instiki>
git checkout -- db/production.db.sqlite3
ruby ./instiki

will suffice to reset the database.

Forum: Instiki – Topic: Installation problem

Thanks for your reply.

I have only one “web”.

Unfortunately I still get exactly the same result when using the address that you provided in the above post?

Forum: Instiki – Topic: Installation problem

I assume you’re running on localhost?

In that case, you should be able to access the URL

http://127.0.0.1:2500/

If you have more than one wiki (“web” in Instiki’s idiosyncratic parlance), this will redirect to

http://127.0.0.1:2500/web_list

If you have only one web configured it will, instead, redirect to the HomePage of that web.

Forum: Instiki – Topic: macOS nokogiri

Hmmm. That’s unexpected. You can edit the Gemfile to replace the line

gem "nokogiri", '~>1.7.0'

with

gem "nokogiri", '~>1.6.0'

which should work fine.

Or you can install a more recent version of Ruby (current is 2.4.0; you have 2.0.0).

Forum: Instiki – Topic: .png files displaying only intermittently

I have been experiencing a weird bug, I wonder if someone knows a fix? On my personal (locally-stored) instiki, I have a bunch of .png files (not huge, all less than 1MB), displayed on various pages. Occasionally I will navigate to a page and instead of displaying the images, it will show me the prompt that shows up when you include an image that has not yet been uploaded – something like nice-pic.png? , in gray. When I click the “?”, it does one of two things: either it initiates a download of the .png file, or it shows me the image in my browser (but on a blank page, with nothing besides the image). In one case this bug resolved itself – after reloading a few times the images showed up again. In another case that didn’t work, and I had to remove the instances of “[[nice-pic.png:pic]]” from my source, submit it, then add the instances back in, and submit one more time.

Any ideas??? Not a big deal, but kinda annoying.
