To exchange the information, the addin and the application must respect the current format.
######### Addin -> Application #########
All the commands are in the form xx; with x being a character.
This is because of a weird bug within the addin that, for some reason, messes up the bits
after the first 3-4 characters. Therefore 3 characters long commands must be the maximum.
Here are the different commands. The first character represents the command,
the second character 'X' represents the argument.
Subreddit:
To connect to a specific subreddit, the command is sX;
Since only one character is allowed the different subs are hardcoded into the addin.
't' = /r/TalesFromTechSupport
'r' = /r/TalesFromRetail
'n' = /r/NoSleep
'c' = /r/Caddit
'a' = /r/AskReddit
'v' = viedemerde.fr (to be implemented)
Post:
Once the user has selected a post, the addin sends the rank of the post, which is interpreted
by the application as its ID.
The command is pX; and the rank of the post is in the range A-Y (25 posts is the maximum).
More characters:
Due to the reception buffer limit of 1 ko, if the application sends that the transmission is not yet finished,
the addin sends ak; once it has finished storing the characters sent.
Next page:
If the application sends that there is more, the user can press a button to send np; which will prompt the
application to send the next 5000 o. The 5000 o limit is because of the RAM limit; there are long posts and the
addin may not be able to stock all the data, so it is transferred with a 5000 o max.
######### Application -> Addin #########
The data read by the addin must be in some kind of weird custom xml format.
################
NOTE: ALL communications MUST be ended with a quote ("), to inform the addin that the transmission is finished.
Therefore you must replace all quotes (whether backslashed or not) with the 0x81 character.
If you still have data to send (reached buffer limit) end your communication with a '<' and then a quote.
If you have reached the 5000 o limit but still have data to send, end it with a ';' then a quote.
################
Since < and > are special characters, replace them with 0x7F and 0x80 respectively.
Don't replace them with &gt; and &lt;, they will be displayed as "&gt;" and "&lt;".
Data for posts:
<r subreddit> <p content of post> <p content of second post> ...
You can customise the subreddit attribute and the contents, you can put whatever you want as long as it's not
a quote or a '>'. Example:
<r /r/AskReddit> <p People of Reddit, where are you banned from and why?\n/u/ArtyStickyGuy 3525 upvotes /r/askreddit>
Data for comments:
<t Text+title of post> <1 first level comment> <2 second level comment> <3 third level comment> <1 another first lvl comment>
Basically the post data must be in the <t> tag, and the comments must be in a numbered tag from 1 to 9.

/*Here is how a character is defined.
Each character is 7 pixels high. The length is defined by you in the length array.
Because some characters (ex: m, M) are 5 px wide, the total amount is >32 bit,
so the character is stored in an array of 2 longs. The first long is only used if
the character is >32 bit.
For example, the character 'M', of length 3, is the following in binary:
00000
10001
11011
10101
10001
10001
00000
You must not forget the "00000" at the end, else your character will be shifted down by a pixel.
Now just remove the newlines in the character. You should get: 00000100011101110101100011000100000
Put that in a binary to decimal converter and you've got your number representing the character.
Also, make sure to define the correct length, else it will display gibberish.
