Developer's Year-Long Journey Building an ASN.1 Compiler in D Programming Language
By
BradleyChatha
A baker's-dozen of insight crammed into one ring.
Summary
A developer shares their year-long journey creating an ASN.1 compiler in the D programming language called 'dasn1'. The article details the technical challenges of implementing ASN.1 (Abstract Syntax Notation One) specifications, including handling complex encoding rules like BER, DER, PER, and XER. The author discusses their motivation stemming from work on a toy async I/O framework called Juptune, and explains why they chose D over other languages. The compiler is still a work in progress, with the post focusing on implementation details, tool output examples, and technical insights rather than promoting the incomplete tool.

ASN.1 is a standard for describing data structures and encoding rules for serialization and deserialization
The name of the tool is dasn1
