Re: [Pdl-general] pgplot instructions for Big Sur macOS

[Ed .]

Hi Karl,

GitHub Actions are all explained in the link I gave in my previous message 😊 
(spoiler: it’s a classic example of cloud computing)

By “more modern” I’m referring to one of the many other possibilities like 
PLplot, Gnuplot, Prima – of the ones that already have PDL support (and that 
have better RGB support, among other features – see 
https://en.wikipedia.org/wiki/PGPLOT for info on e.g. PG2PLplot, a transition 
library)! The harm is in needing to ensure that ideally all of the PDL 
distribution (which has 99 separate components) works, in every release, which 
is a major task for the maintainer.

A good solution would be to finally start pulling “PDL” the distribution into 
some of its component parts, as has long been discussed: for instance PDL::Core 
with maybe just the REPLs and the packages imported by “use PDL” would be a 
separate distribution; the various Proj libraries could be a separate 
component; the PGPLOT another; maybe GSL another one. That way if 
PDL::Graphics::PGPLOT needs fixing, that can be done (and released) 
independently.

Best regards,
Ed

Right. I took a look at that yml file and I can sort of see what is going on. 
On what machine is that CI stuff being run?

Re FreeBSD. Are there many users? I have no idea how ports files would work on 
that distribution, I haven’t even learned how to do this on Macports or 
Homebrew (though I should), but I can certainly advise someone on the command 
line tricks needed to build it.

PGPLOT is not really ‘in PDL’. The module PDL::Graphics::PGPLOT is perl only, 
and depends on PGPLOT module being present and working - which is not part of 
PDL (and in fact predates it). I see no harm in leaving it in?

I would be interested to know what you mean by ‘more modern alternatives’. Such

CI is “continuous integration”, run every time a commit is pushed to the server 
(or a pull request is created or updated) to give instant feedback on problems. 
GitHub Actions is the new-ish service provided by GitHub for this. It’s much 
better than Travis now is, given Travis are deliberately turning off their

and are relevant today, fixes up the makefile generator, and changes one line 
of code in the png driver to avoid an error.

cheers

Hi Karl,

Could you capture on here what lines of code etc you changed, hopefully along 
with all the software versions you used etc, so that ideally someone else 
arriving fresh could do exactly what you did and get the same results?

Best regards,
Ed

Re: [Pdl-general] pgplot instructions for Big Sur macOS

Hi Ed

Sorry for the dumb question - can you explain what ' GitHub Action CI’ is? Do I 
need to know about it?

Karl

[Pdl-general] PDL 2.026 released to CPAN

[Derek Lamb]

Dear PDL users,

Ed recently released PDL 2.026 to CPAN.  (https://metacpan.org/release/PDL)

There are several notable changes since the last announcement to this email 
list, of PDL 2.020 on 2019-12-11.  Thanks go to @mohawk2 (Ed), @wmlb (Luis 
Mochán), @newville (Matt Newville), and @sebastic (Bas Couwenberg) for their 
contributions, as well as to the users who filed bug reports.

User-visible changes:

* Refactor the documentation system to handle multiple functions with the same 
name (e.g., "max") and some indication from 'apropos' as to which module the 
function is in;

* Added function PDL::IO::Pic::imageformat to determine the format of an image 
file;

* Fixed PDL::IO::FITS::wfits so that explicitly setting BITPIX works;

* Fixed PDL::IO::FITS::rfits handling of BLANK values in some Rice-compressed 
images;

* Removed the extrapolation code from PDL::GSL::INTERP that stopped working in 
recent GSL versions;

* Many additions to the PDL::Matlab documentation.

Under-the-hood changes:

* Many fixes to spelling in documentation and code;

* Fixes to various build components including compilation, tests, and 
diagnostic information;

* Many simplifications and fixes to POD markup.

Please report any issues you find to the mailing list (good), or create an 
issue (better) or a pull request (best!) on GitHub.  Thanks, and Happy PDL-ing!

Derek
