This is a command line tool written in Python. It displays all the differences between two database schemas. The schema are provided as SQL dump. 1. ExampleInputdb1.sql: sql dump of a database with ... [More] a single table: 'person' CREATE TABLE `person` ( `last name` varchar(50) NOT NULL, `date_of_birth` varchar(45) NOT NULL, PRIMARY KEY (`last name`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;db2.sql: sql dump of the same database after adding a new table 'car' and modified fields in the 'person' table. CREATE TABLE `car` ( `color` varchar(50) NOT NULL, `number_plate` varchar(50) NOT NULL, `brand` varchar(50) NOT NULL, PRIMARY KEY (`number_plate`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8; CREATE TABLE `person` ( `last name` varchar(50) NOT NULL, `date_of_birth` datetime NOT NULL, `first_name` varchar(45) NOT NULL, PRIMARY KEY (`last name`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;Commandpython compdb.py db1.sql db2.sqlOutput% FIELD: person.date_of_birth `date_of_birth` varchar(45) NOT NULL => `date_of_birth` datetime NOT NULL + FIELD: person.`first_name` varchar(45) NOT NULL + TABLE: car 3 difference(s).2. Notation%: difference +: new field or table -: missing field or table 3. LimitationsCurrently works only with MySQL dumps Obviously this tool cannot detect when the name of a field or a table has changed! 4. MotivationThis script was originally written to help me keep track of the evolution of Django models (hence the Python implementation). Before upgrading a staging server, I would compare the SQL dump from my development database (generated with mysqldump -d or with python manage.py sql) with the dump from my staging server. Note that more sophisticated tools have been developed for this purpose, search for 'django schema evolution' on any search engine to find them. This tool was developed as part of a UML to Django conversion project. 5. FeedbackYour comments and contributions are welcome. [Less]

The Diff Match and Patch libraries offer robust algorithms to perform the operations required for synchronizing plain text. Diff: Compare two blocks of plain text and efficiently return a list of ... [More] differences. Diff Demo Match: Given a search string, find its best fuzzy match in a block of plain text. Weighted for both accuracy and location. Match Demo Patch: Apply a list of patches onto plain text. Use best-effort to apply patch even when the underlying text doesn't match. Patch Demo Currently available in Java, JavaScript, C++, C# and Python. Regardless of language, each library features the same API and the same functionality. All versions also have comprehensive test harnesses. Public UsersGoogle Documents MobWrite Collabedit PatchworkEditor WhiteRoom Mozilla Bespin Your project here... AlgorithmsThis library implements Myer's diff algorithm which is generally considered to be the best general-purpose diff. A layer of pre-diff speedups and post-diff cleanups surround the diff algorithm, improving both performance and output quality. This library also implements a Bitap matching algorithm at the heart of a flexible matching and patching strategy. [Less]
