ANN: numexpr 2.8.8 released
by Francesc Alted Dec. 11, 2023

Dec. 11, 2023

======================== Announcing NumExpr 2.8.8 ======================== Hi everyone, NumExpr 2.8.8 is a release to deal mainly with issues appearing with upcoming `NumPy` 2.0. Also, some small fixes (support for simple complex expressions like `ne.evaluate('1.5j')`) and improvements are included. Project documentation is available at: http://numexpr.readthedocs.io/ Changes from 2.8.7 to 2.8.8 --------------------------- * Fix re_evaluate not taking global_dict as argument. Thanks to Teng Liu (@27rabbitlt). * Fix parsing of simple complex numbers. Now, `ne.evaluate('1.5j')` works. Thanks to Teng Liu (@27rabbitlt). * Fixes for upcoming NumPy 2.0: * Replace npy_cdouble with C++ complex. Thanks to Teng Liu (@27rabbitlt). * Add NE_MAXARGS for future numpy change NPY_MAXARGS. Now it is set to 64 to match NumPy 2.0 value. Thanks to Teng Liu (@27rabbitlt). What's Numexpr? --------------- Numexpr is a fast numerical expression evaluator for NumPy. With it, expressions that operate on arrays (like "3*a+4*b") are accelerated and use less memory than doing the same calculation in Python. It has multi-threaded capabilities, as well as support for Intel's MKL (Math Kernel Library), which allows an extremely fast evaluation of transcendental functions (sin, cos, tan, exp, log...) while squeezing the last drop of performance out of your multi-core processors. Look here for a some benchmarks of numexpr using MKL: https://github.com/pydata/numexpr/wiki/NumexprMKL Its only dependency is NumPy (MKL is optional), so it works well as an easy-to-deploy, easy-to-use, computational engine for projects that don't want to adopt other solutions requiring more heavy dependencies. Where I can find Numexpr? ------------------------- The project is hosted at GitHub in: https://github.com/pydata/numexpr You can get the packages from PyPI as well (but not for RC releases): http://pypi.python.org/pypi/numexpr Documentation is hosted at: http://numexpr.readthedocs.io/en/latest/ Share your experience --------------------- Let us know of any bugs, suggestions, gripes, kudos, etc. you may have. Enjoy data! -- Francesc Alted

(They will become syntax errors in the future.) - The internal representation of integers has changed in preparation for performance enhancements. (This should not affect most users as it is an internal detail, but it may cause problems for Cython-generated code.)

logmerger 0.8.0 released
by Paul McGuire Dec. 8, 2023

Dec. 8, 2023

logmerger 0.8.0 =============== New features: - Added --inline command line option to view merged logs in a single inline column instead of side-by-side columns (side-by-side is the default) - Added jump feature to move by number of lines or by a time period in microseconds, milliseconds, seconds, minutes, hours or days Fixes: - Fixed type annotations that broke running logmerger on Python 3.9. Screenshot: https://github.com/ptmcg/logmerger/blob/main/static/log1_log2_merged_tui_lr… Use logmerger to view multiple log files, merged side-by-side with a common timeline using timestamps from the input files. - merge ASCII log files - detects various formats of timestamps - detects multiline log messages - merge .gz files without previously gunzip'ing - merge .pcap files - merge .csv files Browse the merged logs using a textual-based TUI: - vertical scrolling - horizontal scrolling - search/find next/find previous - jump by number of lines or by time interval - go to line - go to timestamp TUI runs in a plain terminal window, so can be run over a regular SSH session. Installation ------------ Install from PyPi; pip install logmerger For PCAP merging support: pip install logmerger[pcap] Github repo: https://github.com/ptmcg/logmerger
