What’s new in 1.4.2¶

Main changes:¶

Python 2.7 is not supported anymore
Python 3.6 and 3.7 are supported
Several changes to try and make installation easier (on clusters, windows, mac….) and less verbose for users
More explicit names for default saved configurations
Major bug fix in one of the methods for computing synthetic signal
Minor bug fixes in interactive figures
Minor bug fixes in Plasma2D interpolation
New configurations (ITER and JET) available
First version of a class handling 2D XRay bragg spectrometers
First tools for magnetic field line tracing available on WEST
Better documentation, more ressources
More informative error messages
extra tools for computing LOS length, closest point to magnetic axis…
Better PEP8 compliance

Bug fixes for installation on ITER and Gateway clusters #250
Easier installation on Mac #183 (requirements.txt)
Removed explicit compiler specification in setup.py for more flexibility
When sub-packages imas2tofu or mag are missing, the warning is much more concise, but the error traceback is still accessible in a hidden dictionnary for developpers #243
python setup.py clean now doesn’t cythonize
Dropped python 2 support: #228 - merged _GG02 and _GG03 into the _GG file - no longer being tested in travis - no longer packaged in conda - updated README file accordingly - dropped funcsigs dependency - made necessary changes in setup.py - benchmarks/calc_signal_benchmark.py: now working with python 3

Major bug fix in LOS_calc_signal() for computing the synthetic signal of a LOS camera using a particular algortihm : method=’sum’, minimize=’hybrid’, ani=True, #247 #255
Major bug fix in LOS_get_sample() when minimize='hybrid' and minimize='memory' the limits were not set correctly in some cases the formula for sampling a LOS was wrong (los_get_sample_core_var_res).
Minor bug fixes in interactive figures when t=None was used (the interactivity was lost due to wrong formatting of the time array)
Minor bug fixed in Plasma 2D interpolation (interp_t was not being set), imporved error messages #209
Removed unused variable in _Ves_get_sampleS (_GG), in _core.py #190
Gave more explicit names to some variables in _core.py to avoid bugs/typos (eg. I to current) #186
Removed a secondary init function for the class tf.geom.CoilsPF #187
_checkformat_inputs_dgeom now is a function of Rays class
Change default separator in to_dict() from ‘_’ to ‘.’, #228
Rays.calc_kInOut_IsoFlux() is now more flexible (accepts 3d np.arrays as well as lists of np.ndarrays), #188
__repr__() is now overloaded in a more robust way so it falls back to printing the class if get_summary() fails to avoid crashing in debug mode #242
Minor bug in time interpolation in Plasma2D methods #215

Updated information about support of python version #273
Added slides of talk given at PyConFR 2019 conference
Added a gallery in our documentation with 3 different tutorials: - 5 minutes tutorial to show to create a geometry and 1D/2D cameras - Guide on how to create your own Geometry from scratch (vacuum vessel, structures, etc.) - How to compute the signal received by a camera using a synthetic signal. For all of these tutorial, you can see directly the codes and the resulting images, and you can get the source code or download it as a Jupyter notebook!
Minor changes to the web doc: updated install instructions to be “cleaner” now in rST and not HTML), small changes in navigation bar.
Guide on how to contribute to ToFu.

First version of magnetic field line tracing (for WEST only so far, to be improved) #213 #235
First version of 2D XRay Bragg spectrometers for synthetic diagnostics, modelling the diagnotics geometry and providing 2d spectral fitting routines (to be improved) #267
When computing a signal LOS_calc_signal emissivity function can now return a 1D array if t=None #217 #252
Three functions added to tf.geom.Rays: #211
- calc_length_in_isoflux(): compute the length inside a set of isoflux surfaces of each LOS
- calc_min_geom_radius(): compute the minimal geometrical radius (impact parameter) of each LOS
- calc_min_rho_from_Plasma2D(): compute the minimum normalized radius (or any field with a minimum on the axis) for each LOS
New ITER configuration available! #220 #227
New JET configuration available! #282
imas2tofu now more robust with respect to one-time-step only data fields and can handle basic rectangular meshes in addition to triangular meshes #218, #280
More explicit names for default configurations #264
The github homepage now includes a badge to the gitter chatroom #277

Many thanks to all developpers:
