Yorick stuff by TP

Unofficial Yorick 2.1 for Debian packages

I am the current maintainer of all the Yorick-related packages for Debian GNU/Linux. You may find my my personal repository here.

I'm currently working on:

• yorick-mpeg -- mpeg output support (potentially patent-encumbered);
• yorick-ytk -- Tcl/Tk interface and bindings;
• yorick-spydr -- FITS image viewer;
• zerofree -- zero free block in an ext2/3 file-system.

Personal packages

• Cubeview is a 3D FITS file viewer specialized in spectro-imaging. Despite this specialization, Cubeview can be used to do basic visualization on any FITS file containing a 3D array. It can be used as a stand-alone utility but, since it is written in Yorick, it is inherently scriptable. A system of hooks allows custom actions to be repeated automatically when certain events occur. Cubeview features a GTK GUI and is known to work on Linux and Mac OS X assuming Yorick 2.1.05 or above is installed.
• sphere.i is a simple Yorick package to deal with spherical coordinates. Most importantly, it features a function to project object (images, curves) from a sphere onto a plane using azimuthal, Aitoff or Hammer projections, and routines to plot these projected objects.
• clean.i is a trivial Yorick implementation of the CLEAN algorithm for deconvolving imaging data.
• lucy.i is a trivial Yorick implementation of the Lucy — Richardson algorithm for deconvolving imaging data.
• gauss2d is a two-dimensional Gaussian function suitable for data-fitting based on lmfit. It should be merged with gauss.i from the yutils package soon.
• moffat.i contains 1D and 2D Moffat functions usable with lmfit (should soon ship with yutils).
• multiprofile.i allows combining several lmfit-friendly functions (e.g. gauss and moffat) into a more complex lmfit-friendly function, for instance for fitting several spectral lines at a time. This file also contains useful lmfit primitives (linear, linear2d and poly2, an lmfit-friendly equivalent to poly), as well a a function for fitting spectral lines with a cmmon shape (offsetlines). multiprofile.i should soon ship with yutils.
• cpplib is just a sample Yorick plugin in C++. It does nothing useful, but if you want to write a C++ plugin for Yorick and have no clue how to start, please have a look :-) . This "plugin" is split in three: a shared library, a standalone C++ program to use the library, and wrapper code to build the Yorick plugin. Do not hesitate to comment if you find better ways to do things. In particular, I do absolutely no memory management, which will lead to bad memory leaks unless you are very scrupulous about destroying the objects you create.
