0.8.0
What's new in this release:
IMPORTANT CHANGES
- The histogram API has changed significantly! Bins are 0-indexed at the
underflow bin like ROOT and now offer full slicing support. This change is
not backward compatible so please be careful when updating to the latest
rootpy and be sure that you migrate the use of histograms in your code. See
the pull request for more
details. - Moved rootpy.batch to a separate project
General improvements
- ROOT 6 support
- Partial support for Python 3
- Expanded HistFactory/RooFit/RooStats coverage
- Many others improvements...
0.7.0
What's new in this release:
bugfixes
- Fix #49. Don't require python>=2.6 for install, otherwise we get python3
- Check for sys.version < (2, 6) in setup.py
- Eliminate ipython printing (Bool_t)1 when ROOT starts up
- Emit an error wherever the diaper pattern is used
- Sanitize ROOT's message output to ascii, using repr() if it isn't
- Register HistStack with class registry correctly
general improvements
- Documentation
- Defer configuring defaults until finalSetup (#74)
- Switch to pyparsing for C++ template parsing
- Use XDG base directory specificiation
- Add defaults.extra_initializations for further ROOT setup
- Add userdata.BINARY_PATH, unique per (arch, rootversion)
- Use .cache/rootpy/{arch}-{rootversion}/{modules,dicts} to store generated
binaries - defaults: Disable AutoDict generation
- Introduce rootpy/util/quickroot which can get to vital root symbols
without finalSetup (10x speed improvement in import time) - Implement TPyDispatcherProcessedEvent using rootpy.compiled
- Falling back to batch mode should be a WARNING not ERROR
- Numpy code is now moved to the rootpy/root_numpy repository
- Use hash of unique name rather than generating a UUID for dictionary
shared object name - Automatic testing of each commit / pull request on travis-ci
- PEP8 Python code style compliance
- Add TitleView class to plotting.views functionality
- Unit tests
- Rewrite registry code so magical imports are no longer required to make
rootpy aware of what ROOT classes are subclassed in rootpy - Alias ROOT CamelCase methods with snake_case methods
- Improvements to the setup.py script
- New examples for using Trees, Hists, etc
- Make name and title properties for Objects
new externs
- Add extern/pyparsing.py
- Add extern/byteplay
- Add module_facade
- Add inject_closure_values to close over global variables
docs
- Add logger documentation
- Sphinx: Introduce ipython highlighting
- Document a bit more about python's vanilla logging
- Update STL docs
- Add note in CONTRIBUTING.rst about debug python builds
scripts
- Use argparse (argparse is now in rootpy.extern)
- Unify scripts into one rootpy script
- Remove scripts that are still WIP
- Use the new rootpy logger
- Your roosh command history is saved and can be searched
- Multi-canvas and multi-file support in roosh
- Improvements to the root2hdf5 script, that now uses root_numpy for faster
conversion to HDF5
rootpy.interactive (NEW!)
- Add interactive.rootwait, provides wait_for_zero_canvases which blocks
program execution until all canvases are closed - Add canvas_events for closing canvases on middle click
rootpy.context (NEW!)
- Add preserve_{current_canvas,batch_state} and invisible_canvas context
managers - Add preserve_current_directory context manager
rootpy.plotting
- Add xaxis/yaxis properties to plotting.Efficiency
- Implement new fill_array function in root_numpy to fill histograms with
NumPy arrays. Histograms in rootpy now have a fill_array method - TStyle is now subclasses in rootpy as Style. Styles can be used at context
managers using the "with" statement - Add the official ATLAS style and example
- Hist2Ds can be "ravel()"ed, like NumPy's ravel() method that converts a 2D
array into a 1D array by repeating the second axis along the first - Add SetColor to all Plottables to set all colors simultaneously
- Improvements to the root2matplotlib module
- Make style attributes properties
- Add xaxis, yaxis, zaxis properties for Hist classes
- Plottable now gracefully handles deprecation of properties
rootpy.logger (NEW!)
- New logging module for internal and (optionally) external use
- Automatically coloured status level if we're attached to a terminal
- Default rootpy logging level to INFO unless os.environ['DEBUG'] is present
- Redirecting ROOT's errors as python exceptions
- Add a
logsymbol to each subpackage - Add @log.trace() decorator which can be used to log function
entry/exit/duration - Add log.showstack() to log current stack whenever a message is emitted by
log - If there is no logging handler when the first message is emitted,
automatically add one - Automatically log python stack trace if there is a segfault
rootpy.compiled (NEW!)
- Adds an interface for compiling C++ code on demand with CompileMacro
- Add support for inline C++ code definitions
- rootpy.compiled.register_file("mycode.cxx", ["mysymbol"]) then
rootpy.compiled.mysymbol will be generated when requested.
mycode.cxx is located relative to the module where register_file is called - rootpy.compiled.register_code(".. C++ source code ..", ["mysymbol"])
.. same as above but without needing a cxx file on disk
rootpy.memory (NEW!)
- Add log.showdeletion() to show TObject cleanup
- keepalive: function to ensure objects are kept alive exactly as long as
needed
rootpy.util.hook (NEW!)
- Add ability to hook ROOT methods and append properties/methods to existing
classes
rootpy.util.cpp (NEW!)
- New module for parsing C++ syntax.
rootpy.stl (NEW!)
- Compiling arbitrary templated types.
rootpy.tree
- Make root_numpy an optional dependency and remove copy from rootpy
- Reading branches on demand: Only call GetEntry on branches that are
accessed - Add support for branches of array types
- Improvements to the documentation
- The categories module is rewritten and now properly parses the category
syntax (unit tests are included) - Improvements to Tree.Draw
- Dictionaries for branches of STL types are now compiled automatically
- Reverse order of axes expressions in Tree.Draw to match hist argument
order so X:Y:Z maps onto filling along X:Y:Z instead of Z:Y:X
