Tests failing on Windows, file access #62

Closed hustf closed 6 years ago

hustf commented 6 years ago

Running Julia through Cygwin, after installing GNUPlot:

julia> using Gaston

julia> run(`gnuplot --version`)
gnuplot 5.2 patchlevel 2

So far so good. Pkg.test() results in a file path failure that can probably be easily fixed. Just reporting for now:

WARNING: Plotting with an 'unknown' terminal.
No output will be generated. Please select a terminal with 'set terminal'.
WARNING: Gnuplot returned an error message:

I just commited a change to fix the path issue in Windows. I'm worried about the "unknown terminal" issue, though. Can you provide more details, so that I can try to reproduce it?

hustf commented 6 years ago

I believe the 'unknown terminal' is probably related to the new terminal type GNUTERM = sixel? I think this is pretty new, so the version might have an influence. Ref. issue #61.

More details, without checking out master below. I don't know if it's smart in this case, but this packages' tests COULD check for the existence of generated files.

This issue, as such, is closed I reckon.

If you want, I can submit a PR with setup for CI testing on Cygwin. But to get it actually working on this repo and not just on my potential fork of it, somebody must register a token with Appveyor. And as far as I understand, it is only the package owner that can get this secret token from github. The token would authorize Appveyor to listen in and react to changes in this repo. It's a bit of a tedious process the first time(s).

mbaz commented 6 years ago

First of all, I'd like to understand why gnuplot thinks the terminal is unknown, when Gaston explicitly sets the terminal (to "wxt" by default) before every plot.

Can you open gnuplot in a terminal by itself, and run set term? Do you see "wxt" among the options listed? I suspect that your version of gnuplot has no support for wxt.

hustf commented 6 years ago

That seems right. No wxt in the list. ... and I see that the current terminal is x11 again. In order to have sixel permanently, I suppose I must add some pretend system environment variable to my cygwin-set up?

I will add support for sixel soon (pull requests encouraged), so all you'd need to do is run set(terminal="sixel") after you load Gaston.

However, this opens up another problem for me, though: if there are non-wxt compatible gnuplot installations out there, I need to figure out how to support them. I could set the default terminal to x11, but it really is an ugly terminal compared to the alternatives.

One option would be to fall back on x11 for testing only... I need to think about it.
