SimpleCache
SimpleCache.jl is a lightweight (zero-dependency) and simple (one function) package for caching intermediate results to speed up computation on subsequent runs. It is motivated by a scientific workflow where you want to re-run a whole processing pipeline where some results may be expensive to compute.
API
cached(fn::Function, cachename; reset=false)
Cache the result of running fn and store the result in a file cachename. Future invocations will be loaded from the cache rather than re-running fn. To force fn to be run again (and overwrite the cache), either pass reset=true or delete the cache file.
Example
It is convenient to use cached with a do block. For example, the following code will take 10 seconds to run the first time, then return the result instantly the following times.
cached("someresult.jls") do
sleep(10)

endcached uses Julia's built-in serialization, so the cache is not guaranteed to be loadable from a different Julia version or on a different architecture. It is not intended for long-term storage, but for saving time when re-running the same code during development.
