        "description": "# awkg\n\n`awkg` is an `awk` like utility using modern day python language.\n`awk` is amazingly simple, fast and quite handy. However, its domain specific constrain \nsometimes get in our way. `awkg` follows the steps of  `awk`'s design (including its convention for name\ud83d\ude09)\nand exposes full power of the modern day python. \nPython's large set of off-the-shelf existing libraries can of course be imported and used. \n\n# Installation \n```bash\n\n# Install from pypy \n$ pip install awkg\n\n# Install from github\n$ pip install git+https://github.com/thammegowda/awkg.git\n\n```\n\n# CLI usage: \n\n```\n$ awkg -h \nusage: awkg [-h] [-i INP] [-o OUT] [-F FS] [-OFS OFS] [-ORS ORS]\n            [-b BEGIN_SCRIPT] [-e END_SCRIPT] [-im IMPORTS] [-it INIT_PATH]\n            [-v]\n            inline_script\n\nawkg is an awk-like text-processing tool powered by python language\n\npositional arguments:\n  inline_script         Inline python script\n\noptional arguments:\n  -h, --help            show this help message and exit\n  -i INP, --inp INP     Input file path; None=STDIN\n  -o OUT, --out OUT     Output file path; None=STDOUT\n  -F FS, -FS FS, --field-sep FS\n                        the input field separator. Default=None implies white\n                        space\n  -OFS OFS, --out-field-sep OFS\n                        the out field separator. Default=None implies same as\n                        input FS.\n  -ORS ORS, --out-rec-sep ORS\n                        the output record separator. Default=None implies same\n                        as input RS.\n  -b BEGIN_SCRIPT, --begin BEGIN_SCRIPT\n                        BEGIN block. initialize variables or whatever\n  -e END_SCRIPT, --end END_SCRIPT\n                        END block. Print summaries or whatever\n  -im IMPORTS, --import IMPORTS\n                        Imports block. Specify a list of module names to be\n                        imported.Semicolon (;) is the delimiter. Ex:\n                        json;numpy as np\n  -it INIT_PATH, --init INIT_PATH\n                        The rc file that initializes environment.Default is\n                        $HOME/.awkg.py\n  -v, --version         show program's version number and exit\n\n```\n# Example\n\n### Compute mean and std of words per sequence\n```bash\n\ncat data/train.src | awkg -b 'arr=[]; import numpy as np' 'arr.append(NF)' \\\n   -e 'arr=np.array(arr); print(f\"{NR} lines from {FNAME}, mean={arr.mean():.2f}; std={arr.std():.4f}\")'\n```\n### Filter records\n```\n# use print() explicitely \ncat data/train.src  | awkg  'if NF >= 25: print(*R)' \n\nAssign boolean expression to special variable RET to trigger implicit print \ncat data/train.src  | awkg  'RET = NF >= 25'\n\n# print respects the OFS value\ncat data/train.src  |  awkg  'if NF >= 25: print(NR, NF)' -OFS='\\t'\n```\n\n## Special Variables\n+ `NF`  : Number of fields\n+ `NR`  : Record number \n+ `R`   : An array having all the columns of current record.\n+ `R0`  : analogous to `$0` it stores the input line before splitting into `R`; since python does\n not permit `$` in the identifiers, it is renamed as `R0`\n+ `RET` : When this variable is set to Truth value of `true` implicit `print(*R)` is triggered\n+ `FS` : Input Field separator\n+ `OFS` : Output Field separator; Unless explicitly set, `OFS=FS`\n+ `ORS` : Output Record separator\n+ `RS` (Currently Not in use)\n+ `_locals` , `_globals` - all variables in local and global scope\n\nYou are allowed to use any valid python identifiers, than the above variables\n\n## Default import modules \nThese modules are imported by default\n+ `sys`\n+ `os`\n+ `re`\n+ `from pathlib import Path`\n\n\n## Author:\n+ [Thamme Gowda](https://twitter.com/thammegowda)\n\n## Related tools\n+ [pawk](https://github.com/alecthomas/pawk) similar to this repository, slightly different implementation.\n+ [gawk](https://www.gnu.org/software/gawk/manual/gawk.html) GNU awk\n\n\n\n\n",
