. SYNOPSIS
Downloads, decrypts and repackages content from Hoopla
. DESCRIPTION
Uses a HooplaDigital . com account to download DRM-free copies of ebooks, comics,
and/or audiobooks available on the platform . Content that is not already borrowed
on the account will be borrowed if slots are available . Content that is not borrowed
cannot be downloaded .
* E-Books are downloaded to epub files (most) or cbz (rare, picture books) .
* Comic books are downloaded to cbz files .
* Audiobooks are downloaded to m4a files . (single file, and very little metadata available
from Hoopla, such as chapters)
. PARAMETER Credential
Credential to use for logging into Hoopla site .
(Cannot be used with Username and Password parameters)
. PARAMETER Username
Username to use for logging into Hoopla site .
(Cannot be used with Credential parameter)
. PARAMETER Password
Password to use for logging into Hoopla site .
(Cannot be used with Credential parameter)
. PARAMETER TitleId
Specifies one or more title IDs of content to download .
. PARAMETER OutputFolder
Sets the output folder for downloaded content . Defaults to current directory .
. PARAMETER PatronId
Override default patron id for Hoopla . (This is rarely required as most user accounts are only tied
to a single patron) .
. PARAMETER EpubZipBin
Specifies path to epubzip binary . Else look for one beside script, or in system path .
. PARAMETER FfmpegBin
Specifies path to ffmpeg binary . Else look for one beside script, or in system path .
. PARAMETER KeepDecryptedData
If set, don't delete the intermediary data after decryption, before final output file .
For ebooks, this is xml, images, and the manifest . For comics, it is images . For audiobooks,
it is mp4 ts files . This is typically only useful for development or troubleshooting .
. PARAMETER KeepEncryptedData
If set, don't delete the encrypted data as downloaded from Hoopla's servers . This is typically
only useful for development or troubleshooting .
. PARAMETER AllBorrowed
This parameter is deprecated . If TitleId is not set, it is implied that all borrowed titles will
be downloaded .
. PARAMETER AudioBookForceSingleFile
If set, leave audiobook as single file, as if chapter data is not present .
. EXAMPLE
. \Invoke-HooplaDownload . ps1 123456
