rama-demo-gallery VS specter

This is the bank transfer example we show in rama-demo-gallery. There's both Java and Clojure versions of that example. https://github.com/redplanetlabs/rama-demo-gallery

The atomic bank transfer is done as part of function(data). The data record contains fromAccountId, toAccountId, and amount. The function applies the transfer if it's valid (fromAccountId has at least that amount of funds), and no-ops otherwise.

The bank transfer module is particularly neat: https://github.com/redplanetlabs/rama-demo-gallery/blob/mast...

> Another example is Specter. Specter is a generically useful library for querying and manipulating data structures

  package com.rpl.specter;

If you are truly interested in understanding my point of view -- a great way to do it would be to learn how to use this Clojure DSL: https://github.com/redplanetlabs/specter

For deeply nested data, use specter https://github.com/redplanetlabs/specter

Yes :), I needed a fast dijkstra implementation to solve a puzzle in 2021. A pure clojure implementation was too slow so i built one on top of this https://github.com/redplanetlabs/specter

https://github.com/redplanetlabs/specter (very powerful way to express modifications to nested data)

Don't forget about specter which is efficient and compact due to its DSL.

Learn and use specter for nested data manipulation, will take some studying but is a more general solution (https://github.com/redplanetlabs/specter)

For part 1, the version (and other things) are attached to the metadata of each sexp, and a Specter recursive path is used to extract all of the versions.
