💅 NAME 💅

App::p — steroids for your perl one-liners. no like fr, it's the glow-up your one-liners have been begging for 💖

This is page App::p(3) from the User Contributed Perl Documentation, bestie, and we're about to make it make sense ✨

🎀 VERSION 🎀

version 0.0400

🌈 SYNOPSIS 🌈

okay so here's the whole entire vibe:

Usage: p [-lneE etc] 'code'
    The code can make use of:
    r   to File::Slurper::read_text()
    w   to File::Slurper::write_file()
    S   to say()
    p   to print()
    dd  to Data::Dump::dd()
    jd  to JSON::encode (utf8/pretty)
    jl  to JSON::decode (utf8/allow nonref) a thing
    xd  to XML::Hash::LX::hash2xml()
    xl  to XML::Hash::LX::xml2hash()
    yd  to YAML::Dump()
    yl  to YAML::Load()
    xj  to convert an xml file to json
    jx  to convert a json file to xml
    get,head,getprint,getstore,mirror from LWP::Simple
    sum,first,min,max,zip,uniq,any,all,none ... all of List::AllUtils

    Examples:

    p 'dd [File::Spec->path]'   # dynamically load arbitrary modules
    p -pe 's/foo/bar/' foo.txt  # use your favorite options like -lane
    p 'say "hello world!"'      # -E is assumed if no options are provided
    p 'dd yl r "config.yml"'    # chain commands
    p 'S sum 1,2,3,4'           # all of List::AllUtils is at your fingertips
    p 'dd ExtUtils::Installed->new->modules' # list all installed modules
    p '  dd xl r "/etc/xml/xml-core.xml"'    # print dump of hash converted xml
    p 'p xd xl r "/etc/xml/xml-core.xml"'    # print xml converted from hash
    p 'p get "http://icanhazip.com"'         # print contents of url
    p 'p xj "file.xml"          #   (xj xml to json )print xml's equivalent json
    p 'p jx "file.json"         #   (jx json to xml )print json's equivalent xml
    p 'dd uniq map $_->{ostext}, @{ jl get "http://www.cpantesters.org/distro/A/App-p.json" }' # have fun!
bestie the way this works is: every single one of those tiny little names (r, w, S, p, dd, jd, jl, xd, xl, yd, yl, xj, jx, and the whole LWP::Simple + List::AllUtils squad) is just there, pre-loaded, waiting for you. no use statements, no setup, no drama. you type the letter, it does the thing. iconic 💅
