Hi Nisarg,
thanks for your interest. It would be better to start from an existing 
parser, but I haven't studied the library you suggest. It can be part of 
your proposal though.

About formatting, PMA_SQP_format() is only used in 'query_only' mode. 
The formatting you can see comes from CodeMirror.

To see examples, I replied to you in one of the feature tickets, but in 
general, this should give you a good start:

git grep PMA_SQP_parse
git grep PMA_SQP_analyze
