embedfs

Embed directories of files in your executable. It's like staticRead/slurp for whole directories.

Installation

nimble install embedfs

Usage

import embedfs
const data = embedDir("data")
echo data.get("somefile.txt").get()
doAssert data.get("nonexisting.txt").isNone

for filename in data.listDir():
  echo filename

for filename in data.walk():
  echo filename

You can also change from embedding at compile-time (the default) to reading files from disk at runtime for testing purposes with embed = false, because sometimes it's nice to not have to recompile the whole program just to get new assets:

import embedfs
const data = embedDir("data", embed = false)
writeFile("data"/"foo.txt", "foo")
doAssert data.get("foo.txt") == some("foo")
writeFile("data"/"foo.txt", "new value")
doAssert data.get("foo.txt") == some("new value")
