Open Source COBOL Libraries

LIXA (LIbre XA) is an open source and free Transaction Manager implementing the distributed transaction processing "XA specification" and "TX (transaction demarcation) specification" according to the X/Open CAE Specification. LIXA implements even XTA: XA Transaction API, an innovative API that implements XA transactional context passing among different applications. LIXA is a Transaction Manager but it's not a Transaction Monitor: this is the distinguishing feature of the project. LIXA technology enables every application container, like a web server or a shell, to become a two phase commit application server. The client/server architecture of LIXA allows many application containers to share a single LIXA (state) server: this is ideal when horizontal scalability is a must and many identical application containers must refer to a single transactional environment. LIXA can be used with the C, C++, Java, Python and COBOL programming languages.

This project will convert Cobol Data Files to/From Csv files using a Cobol Copybook.

This project will convert Cobol Data Files to/From Xml files using a Cobol Copybook. It provides both a Batch and Java/JVM for conversion

Smallest possible is a curated repository whose aim is somewhat playful yet useful: collecting the “smallest possible syntactically valid files” across a large variety of programming, scripting, markup, and binary file types. For example, the repository might include the minimal valid HTML file, minimal valid PDF, minimal valid executable, minimal valid image file, and so on. It serves both as a curiosity and as a utility for developers and testers who might need tiny stub files for testing tooling, parsing, or file-type handling. Because each file targets minimal syntactical correctness, the repository is valuable for edge-case testing (e.g., parsers handling smallest valid inputs). The project is open, community-welcoming (pull requests accepted) and carries a public-domain style waiver by the author. Although specialized, its uniqueness lies in spanning many file types and languages uniformly under the “minimal valid” idea.
