Hadd\n\nThis is a python package to allow usage of hadd (from ROOT CERN) in parallel. It allows adding histogram and `.root` files. The addition will occur in blocks instead of one at all. It was designed to work with limited memory (local development primilary). The addition will use `multiprocessing` if avilable in your python enviroment. \n\n## Requirements:\nThe minimum supported python version is 3.6. \n| Python version | Supported  |\n|:--------------:|:----------:|\n| 2.x            | NO         |\n| 3.1-3.5        | NO         |\n| 3.6            | YES        |\n| 3.7            | YES        |\n| 3.8            | YES        |\n| 3.9            | YES        |\n| 3.10           | YES        |\n| 3.11           | YES       |\n\n\n## Install \n\n## from pypi\n\nyou can install the package directly from pypi repository\n```\npip install parallel-hadd\n```\n\n## build manually\n1. clone this repository\n\n```\ngit clone https://github.com/MohamedElashri/hadd-parallel\n```\n\n2. build the package from source using `pip`\n\n```\npip3 install ./hadd-parallel\n```\n\n## Manual\n\nThe command to use the package is \n\n```\nphadd\n```\n\nyou can use it as the following (with default arguments)\n\n```\nphadd out.root *.root\n```\n\n[![asciicast](https://asciinema.org/a/GdfRIzl5uF8OQ1GrMwAhg8qXt.svg)](https://asciinema.org/a/GdfRIzl5uF8OQ1GrMwAhg8qXt)\n\nwhere `out.root` will be the output file the contains all the `*.root` files. \n\nmore information about how to customize the settings are available on program help page\n\n```\nphadd -h\n```\n\n\n## Help page\n\n```\nusage: phadd [-h] [-t TMPDIR] [-j NUM_JOBS] [-n NUM_FILES] [-f] [-s] [-l {DEBUG,INFO,WARNING,ERROR,CRITICAL}] [-v]\n             output_file input_files [input_files ...]\n\nHadd ROOT histograms in parallel\n\npositional arguments:\n  output_file           the output file\n  input_files           one or more input files\n\noptional arguments:\n  -h, --help            show this help message and exit\n  -t TMPDIR, --tmpdir TMPDIR\n                        the temporary directory to store intermediate files\n  -j NUM_JOBS, --jobs NUM_JOBS\n                        the number of jobs to run in parallel , [default cpu_count * 2 = {N_JOBS}\n  -n NUM_FILES, --num_files NUM_FILES\n                        the number of files to hadd at once\n  -f, --force_overwrite\n                        force overwrite of output file\n  -s, --save-tmp        save the intermediate files, otherwise they will be deleted (which is the default)\n  -l {DEBUG,INFO,WARNING,ERROR,CRITICAL}, --log {DEBUG,INFO,WARNING,ERROR,CRITICAL}\n                        the log level, [default Warning]\n  -v, --version         show program's version number and exit\n\n```\n\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmohamedelashri%2Fhadd-parallel","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmohamedelashri%2Fhadd-parallel","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmohamedelashri%2Fhadd-parallel/lists"}
