an elegant slicer for a more civilized age

ALPHA - REPOSITORY WILL MOVE BEFORE MAY 1ST 2020

stream-dagger is a command line tool designed to:

• receive a single STDIN input stream
• efficiently split it based on a wide array of tunable criteria
• aggregate and emit detailed statistics about the resulting chunks
• possibly form a Directed Acyclic Graph (DAG) from the individual stream parts
• possibly stream the DAG on STDOUT in format understood by e.g. ipfs

Further documentation for individual use cases will be available in several days (https://github.com/ipfs/DAGger/issues/5). Until then some basic example snippets:

go get -v -u github.com/ipfs-shipyard/DAGger/cmd/stream-dagger

cat {{somefile}} | stream-dagger --ipfs-add-compatible-command="--cid-version=1"

find {{somedirectory}} -type f -exec sh -c '
perl -e "print( pack( q{q>}, -s \$ARGV[0]))" {} && cat {}
' \; | stream-dagger --multipart --ipfs-add-compatible-command="--cid-version=1"
