Issue #650: load helper should fallback to test_data_dir (yt_analysis/yt)

by Kacper Kowalik

New issue 650: load helper should fallback to test_data_dir https://bitbucket.org/yt_analysis/yt/issue/650/load-helper-should-fallback-… Kacper Kowalik: This is related to [PR99](https://bitbucket.org/yt_analysis/yt-doc/pull-request/99/adding-color…. I've initially wanted to as @chummels to modify his `cmap_images.py` script as follows: ``` #!diff --- a/cmap_images.py +++ b/cmap_images.py @@ -1,8 +1,9 @@ from yt.mods import * import matplotlib.cm as cm - +import os # Load the dataset. -pf = load("IsolatedGalaxy/galaxy0030/galaxy0030") +pf = load(os.path.join(ytcfg.get("yt", "test_data_dir"), + "IsolatedGalaxy/galaxy0030/galaxy0030")) # Create projections using each colormap available. ``` Then I thought that if we could make `load` fallback to that path if `args` doesn't exists, that would come handy for docstrings tests.

Issue #649: PlotWindow should have toggles for the annotated axes and colorbar (yt_analysis/yt)

by Nathan Goldbaum

New issue 649: PlotWindow should have toggles for the annotated axes and colorbar https://bitbucket.org/yt_analysis/yt/issue/649/plotwindow-should-have-toggl… Nathan Goldbaum: Something like this: ``` p = ProjectionPlot(pf, 2, 'Density') p.toggle_axes() p.save() ``` for a PlotCollection-like experience. Or, ``` p = ProjectionPlot(pf, 2, ['Density', 'Temperature']) p.toggle_colorbar() p.save() ``` to remove the colorbar but leave the annotated axes. Responsible: ngoldbaum

yt Strategy Meeting Monday the 22nd

by Matthew Turk

Hi all, I'd like to call a brief, approximately one hour, strategy meeting on Monday, April 22nd at 3PM Eastern. This will cover where yt is at, where we can go, and how things are progressing. Some of this will be dedicated to progress updates (from me and others) as well as soliciting feedback on a number of things. Many other projects -- notably Cactus -- do these on a fixed schedule, so based on the success/failure of this one we can consider having them semi-regularly. The agenda I would like to cover will include: * yt 3.0 status, including near/long term plans for development and support for non-grid codes * Rundown of all YTEPs accepted and outstanding * yt's "presence" on the web * 3.0 paper I will also be soliciting feedback in roundtable style on: * How are we doing? * How is the procedure for code contributions working? * How is the yt "infrastructure" meeting people's needs? (Mailing lists, Bitbucket, etc) * Where are energies being spent that could be better spent elsewhere? If you have either agenda items or discussion items, please reply to this email and suggest them. I think having a large presence at this meeting would be very useful, so if you are able to make it, please try to do so. It'll be held as a google hangout, and I'll send details here when it starts up. If there's a pressing need to reschedule, please write in reply to this email. Thanks, and looking forward to seeing you there, Matt

Issue #647: Volume Rendering + Log Fields + Zeros (yt_analysis/yt)

Issue #646: Trailing Spaces in FLASH datasets carried over to output file names in SlicePlot (yt_analysis/yt)

by James Guillochon

New issue 646: Trailing Spaces in FLASH datasets carried over to output file names in SlicePlot https://bitbucket.org/yt_analysis/yt/issue/646/trailing-spaces-in-flash-dat… James Guillochon: All variables in FLASH are internally represented by a 4 character string, if a variable has less characters, it has trailing spaces, for instance, carbon is "c12 ". When you perform a SlicePlot on one of these variables, the output file is annoyingly named "mysimulation_c12 .png". This is only an issue for element names when using either the 13 or 19 element burn network. Responsible: ngoldbaum

Issue #645: Setup script should complain or error out when using intel compilers (yt_analysis/yt)

by Nathan Goldbaum

New issue 645: Setup script should complain or error out when using intel compilers https://bitbucket.org/yt_analysis/yt/issue/645/setup-script-should-complain… Nathan Goldbaum: As noted on the list, when yt is compiled with icc, there are mysterious hangs during some operations. We should be able to detect that and either error out or print a warning rather than silently generate a broken installation.

Documentation Sprint and Creating BB Issues When You See a Gap

by Cameron Hummels

Hey peeps, After talking with Matt at some length about the yt documentation, we thought it might be a good idea to have a documentation sprint in a few months when we've moved over to yt 3.0 as the focus of our development. The docs in general are good, but there are some gaps here and there with some functionality not present in the documentation. I'm not proposing an entire (or even partial) rewrite of the docs, as I think that would be counterproductive. I'm simply thinking we could fill in the holes to make sure all of the cool stuff in yt is written up so people know how to use it. Now, I know doc writing is not often fun, but I think this could be really beneficial to our user base, and actually cut down on the amount of time we have to respond to new users on the mailing list and irc (as well as making it easier for people to use yt). What I'm asking from you is if you encounter something that you don't think is well documented in the formal docs (not simply the docstrings), could you take a moment to create a bitbucket issue about it? You don't even have to fix it then, just note it, so we know where to work when we do the sprint in a few months. Anyone else have any other ideas about this?
