Parses the provided JSON file, and outputs it as equivalent shell commands to set shell variables.

It is not very sophisticated, it doesn't need to be for my purposes. I would have just used jq, but it has a few shortcomings that meant I couldn't make it work for parsing MCE Buddy files emitted by Channels DVR.

eval $( json2shell <json filename> )

Channels DVR can optionally emit JSON files alongside recordings, in the style used by MCE Buddy. Unfortunately MCE Buddy is exclusive to Windows. The information is still valuable so I wanted to take advantage of that extra info when post-processing Channels DVR recordings.

This little tool gets the information in those simple JSON files into shell variables so I can use them easily in my scripts.

Suppose I have a file Courageous Love (2017) 2021-05-13-2200.json that Channels DVR created which has the contents:

{"Description":"Alex has to choose between saving his family's company or following his heart.", 
 "Episode":0,"Genres":["Drama","Romance"],"IsMovie":true,"IsNews":false,"IsSports":false,
 "MetadataGenerator":"Channels DVR","OriginalBroadcastDateTime":"2017-03-21T00:00:00Z",
 "RecordedDateTime":"2021-05-13T22:00:00Z","Season":0,"SubTitle":"",
 "Title":"Courageous Love (2017)"}

running json2shell on that file produces:

Description="Alex has to choose between saving his family's company or following his heart."
Episode=0
Genres=( "Drama" "Romance" )
IsMovie=1
IsNews=0
IsSports=0
MetadataGenerator="Channels DVR"
OriginalBroadcastDateTime="2017-03-21T00:00:00Z"
RecordedDateTime="2021-05-13T22:00:00Z"
Season=0
SubTitle=""
Title="Courageous Love (2017)"

Noote that the Genres array in the JSON file has been converted to the bash shell syntax for array variables.

By using eval on the output of json2shell, the metadata from the JSON file will be available as equivalent shell variables in shell scripts. This can be useful to determine where to link the recording in a Plex media heirarchy, for example.

For example, my spouse enjoys a particular genre of movie, and so in my scripts, those movies are moved directly to her personal Movie folder, not the main one that the family shares.

This executable depends on the cjson library to parse JSON into something C can digest. Thank you, Dave Gamble.
