solr

I guess you live in a more modern workspace than I do. I just picked an open source project that (A) I know we use at work, and (B) I know is written in Java. I picked a random source file that sounded like it would have some mutable state, and the very first functions below the constructor were a trivial getter and setter around a private ivar. https://github.com/apache/solr/blob/main/solr/core/src/java/... I'm a little surprised it was in literally the first place I looked, but I'm not surprised that it was easy to find. "Use private ivars and write getters and setters to encapsulate your state" was probably the second thing that a generation of CompSci students learned in their first programming class, right after "an object is an instance of a class."

Oh! Damn it I forgot about manticore -- I had seen it before but forgot to include it. Eventually all of these projects will be highlighted on Awesome F/OSS (https://awsmfoss.com), but for now I'm just going to dump my bookmarks here for other people, since I'm leaving awesome projects out: Search Engines AWS OpenSearch https://github.com/opensearch-project/OpenSearch https://github.com/opensearch-project/OpenSearch-Dashboards https://github.com/opensearch-project/perftop https://github.com/go-ego/riot https://groonga.org/ https://github.com/groonga/groonga https://github.com/meilisearch/MeiliSearch https://github.com/mosuka/bayard https://github.com/nezaboodka/nevod https://github.com/searx/searx https://github.com/stryku/okon https://github.com/toshi-search/Toshi https://github.com/typesense/typesense https://github.com/valeriansaliou/s
