Python based implementation which uses gitpython to check the current version of a sentence in a git repo

I need a Python based implementation which uses gitpython to find the changes done to sentences in text files over mutiple commits. Each sentence is stored in a {} with a unique ID in one line. Over time document writers update these sentences(in multiple text files), but keep the same ID. The following is what should be accomplished: 1) Plugin based text parser. Periodic pull of code. 2) Scripts to setup mySQL and MongoDB tables. 2) MySQL population from gitpython based diff using the parser plugin : The sentences should be used to create a UniqueID , which is the one of the primary Key for the mySQL table. This mySQL table is used to store the objectId of a mongoDB entry and the sentence itself. Logic should be in place to handle duplicates , for example before adding a new UniqueId(which is the normalized version of the sentence), a cheque should be done if the TextUniqueId exists already. The TextUniqueId will always exist. A table per directory is needed. eg : "Test this piece of code" UniqueId TextUniqueId Sentence MongoDBObjectId _________ ______ __________ _______________________ testthispieceofcode 34778 "Test this piece of code" 98181818772 modifythisportion 13568 "Modify This portion" 91919999454 3) MongoDB population : The mongoDB table will record the changes to the sentences eg : a) For a sentence which was updated multiple times. ObjectId : 98181818772, {CurrentVersion : "Test this piece of code", // This is the setence TextUniqueId: 34778, // UniqueId stored in the text file Verb: "Test", // The plugin parser logic should have hooks to isolate regex matches gitcommit : cedadea // git commit from gitpython version :current }, {PreviousVersion : "Delete this piece of code", TextUniqueId: 34778, // The ID is always the same. Verb: "Delete", // The plugin parser logic should have hooks to isolate regex matches gitcommit : acdccdd, // git commit from before the current commit version : updated, }, {PreviousVersion : "Modify this piece of code", TextUniqueId: 34778, Verb: "Modify",// The plugin parser logic should have hooks to isolate regex matches gitcommit : 4f654cd // git commit from before the second commit version : updated }, {PreviousVersion : "Rectify this piece of code", TextUniqueId: 34778, Verb: "Rectify", // The plugin parser logic should have hooks to isolate regex matches gitcommit : 67dedac // git commit from before the second commit firstVersion : Yes version : Created // Can be Created,Updated,current, Deleted }, b) For a sentence which was updated once and then deleted ObjectId : 91919999454, {CurrentVersion : "Modify This portion", // This is the setence TextUniqueId: 13568 , // UniqueId stored in the text file Verb: "Modify ", // The plugin parser logic should have hooks to isolate regex matches gitcommit : afd65612 // git commit from gitpython version : Deleted // can be Created,Updated,current, Deleted }, {CurrentVersion : "Rectify This portion", // This is the setence TextUniqueId: 13568 , // UniqueId stored in the text file Verb: "Rectify ", // The plugin parser logic should have hooks to isolate regex matches gitcommit : afd65612 // git commit from gitpython version : Created },
