//! output the statistics of text, like a wc of linux command. //! //! ```text //! Usage: //! aki-stats [options] //! //! output the statistics of text, like a wc of linux command. //! //! Options: //! -a, --all output the all statistics of text //! -b, --bytes output the byte counts //! -c, --chars output the unicode character counts //! -l, --lines output the line counts //! -m, --max-line-bytes output the maximum byte counts of line //! -w, --words output the word counts //! --locale <loc> locale of number format: en, fr, ... posix //! -?, --query <q> display available names of locale and exit //! //! -H, --help display this help and exit //! -V, --version display version information and exit //! //! Examples: //! Outputs the line count: //! echo -e "acbde fghi\njkln opqr" | aki-stats -l //! Outputs the byte count: //! echo -e "acbde fghi\njkln opqr" | aki-stats -b //! Outputs the word count: //! echo -e "acbde fghi\njkln opqr" | aki-stats -w //! ``` //! //! # Examples //! //! ## Example 1: the all statistics //! //! Output the all statistics of input text. //! //! command line: //! ```text //! cat fixtures/sherlock.txt | aki-stats -a //! ``` //! //! result output: //! ```text //! lines:"26", bytes:"1207", chars:"1207", words:"226", max:"83" //! ``` //! //! ## Example 2: the line count //! //! Output the only line count. //! //! command line: //! ```text //! cat fixtures/sherlock.txt | aki-stats -l //! ``` //! //! result output: //! ```text //! lines:"26" //! ``` //! //! ## Example 3: the byte count with locale en //! //! Output the only byte count. //! //! command line: //! ```text //! cat fixtures/sherlock.txt | aki-stats -b --locale en //! ``` //! //! result output: //! ```text //! bytes:"1,207" //! ``` //! //! # Library example //! //!
