#!    Name: up_sendnow.sh
#!  Author: kittykat
#! Version: 2025.02.15
#!    Desc: Add support for uploading files to a new host
#!    Info: Files are accessible at https://send.now/<hash>
#! MaxSize: 100GB
#!  Expire: 30 days
#!   Usage: Copy this file into the ./${ScriptDir}/hosts/ folder
#!
#!
#! ------------ REQUIRED SECTION ---------------
#! @[UPDATE] ListUploadHosts: This string is loaded into mad.sh and allows dynamic handling of new url data
#! Format: '/HostCode/HostNick/HostFuncPrefix@'
#! HostCode: <aUniqueCodeForHost> (ie. 'fh' for filehaus -- cannot be used by other hosts)
#! HostNick: What is displayed throughout MAD output
#! HostFuncPrefix: <aUniqueStringThatMustPrefixHostFunctions> ie. 'fh' -- fh_UploadFile()
#!   * Note: Must begin with a letter a-z (functions beginning with numbers are no bueno)
HostCode='snow'
HostNick='send.now'
HostFuncPrefix='snow'
#!
#! !! DO NOT UPDATE OR REMOVE !!
#! This merges the Required HostAndDomainRegexes into mad.sh
ListUploadHosts=${ListUploadHosts}'/'${HostCode}'/'${HostNick}'/'${HostFuncPrefix}'@'
