Automatic image building

[TiagoCavalcante]

@rocky I think it'd be nice [and less time consuming] to have a automatic image building which runs every week if it don't overrun the minute quota.

[rocky]

The build process isn't stable right now; nor is it feature wise where I'd like it to be. Things have been changing too rapidly.

Automating release of something that is in a somewhat chaotic state I think will add to yet another source of flakiness.

We don't have to make a new docker image every week, we just do when I think it is warranted. And we make PyPI/github releases when we think it is right to release.

Normally, I'd say well if this is something you want to do, go for it. But I know it is just going to detract from getting things stable. And the images might be unstable (automatically) too.

I think this is a good idea for down the line, but just not right now.

Ok, this makes sense, maybe build the image in every release of the other mathics repositories?

Also @rocky when I try to build with the following command:

cd docker && docker build -t mathics .

It gives the following error: /bin/sh: 1: cd: can't cd to src/mathics-django. I saw that in the Dockerfile doens't looks to download Mathics Django from anywhere.

And when I try to build with the following command:

cd docker && docker build -f Dockerfile-dev -t mathics .

It gives the following error:

We use docker-compose, not docker.

Install remake and type remake --tasks.

In general, just use the Makefile targets.

@TiagoCavalcanteTrindade here is something I bet you could fix up is getting the SVG tick marks aligned in Plot[]. For example look at

Plot[Sin[x] Cos[1 + x], {x, 0, 2 Pi},PlotRange->{-1,1}]

and you'll see things are a real mess.

If this is of interest to you, I'll try to remember the last change I made to get these to at least start appearing again.

I have given up for the day trying to get DensityPlot working. The main problem I have is on the Mathics end in figuring out how to get the vertex color information at the place where it is needed in the svg formatter.

[rocky]

Change that. I remember now those tick marks are fine. It is the lines extending below the line in the bar charts, e.g.

BarChart[{{1, 2, 3}, {2, 3, 4}}]

and I am not sure the one extending bellow the line in

Plot[Abs[Sin[t] / (t + 1)], {t, 0, 4 Pi}, Mesh->Full, PlotRange->{0, 1 / 2}]

is that useful too. Dunno - what do you think?

[TiagoCavalcante]

@rocky yes, the tick numbers are all over the tick lines (even in BarChart they're too close), also what do you think of increasing the opacity?

@rocky changing the style text-anchor to end in Mathics Core should solve this problem (I made it for -0.5).

Also seeing this now I remembered that we need to increase the responsiveness for smaller screens for svg. I can do it by the same approach used by drawGraphics3d.

When it comes to style issues, I'll go with whatever the other person or person asking things.

Ok. Please put in a PR for that.

Ok. Please do that too. Thanks!
