http://www.ohler.com/ My latest new on my OSS project covering JSON, XML, and GraphQL with Ruby, Go and C. https://github.com/ohler55/slip Mon, 05 January 2026 14:00:01 GMT After years in development SLIP is now public. It is an almost complete Common LISP implementation written in Go. Why is that interesting, SLIP supports Go plugins which allow it to be extended with Go code. https://github.com/ohler55/oj/blob/master/pages/Parser.md Sun, 08 August 2021 00:00:01 GMT The original Oj parser is a performant parser that supports several modes. As of this writing Oj is almost 10 years old. A dinosaur by coding standards. It was time for an upgrade. Oj::Parser is that upgrade. It's faster and has a cleaner option API. https://github.com/ohler55/ojg Sat, 03 July 2021 00:00:01 GMT MongoDB output can now be parsed by the SEN parser. Just pipe output from mongosh to the oj application with the -mongo option. https://github.com/ohler55/ojg Sun, 23 May 2021 00:00:01 GMT Not much changed in the API but the code for encoding structs received a major performance bump. Simple type encoding is still as fast as ever. https://github.com/ohler55/ojg Sun, 18 Apr 2021 12:00:00 GMT OjG received a new addition today. A Tokenizer was added as an alternative to the go json.Decoder except it is an order of magnitude faster. Benchmarks and comparisons at at https://github.com/ohler55/compare-go-json. https://www.ohler.com/dev/pretty.html Mon, 22 Feb 2021 12:00:00 GMT Wouldn't it be nice if more JSON tools supported a truly pretty JSON format? Demand options for truly pretty JSON now! Viva la revolucion! https://github.com/ohler55/graphql-test-tool/blob/master/example/solid-quick.md Tue, 2 Feb 2021 12:00:00 GMT It seemed like a good time to talk about black box testing with GTT since a new super tolerant script file loader was added by using the SEN file parser. https://github.com/UHN/ggql/tree/master/examples/websocket Wen, 30 Dec 2020 12:00:00 GMT With a little time over the holidays I wrote an example of using WebSockets with GraphQL with the golang GGql package. I've been using GGql heavily at UHN and it has been holding up well with subscriptions and auth as well as other layers to make mongo database integration easier. https://github.com/ohler55/ojc/blob/master/misc/compete.md Wed, 09 Sep 2020 12:00:00 GMT Benchmarks and feature comparison with a twist. Real benchmarks but narrated and presented as a track meet. This goes along with the 4.0 release of OjC. https://github.com/ohler55/ojg Mon, 22 Jun 2020 12:00:00 GMT Oj for Go is the fastest Go JSON parser with a full JSON Path implementation that can also be used to navigate just about any Go data. A jq alternative is also included for working with JSON documents on the command line. https://github.com/UHN/ggql Tue, 09 Jun 2020 12:00:00 GMT The lawyers gave the okay to bring GGql open source. GGql is a super fast Go GraphQL package with a much easier to use API. GGql comes out near the top in GraphQL benchmarks. https://www.ohler.com/agoo/index.html Sat, 18 Aug 2018 12:00:00 GMT The latest addition to my open source projects is Agoo, is a high performance web server gem for Ruby. Agoo includes a new publish and subscribe model that the author of Iodine and I worked on together. A short article that describes the API for pub/sub with some example
