CBOR Stream Decoder
CSD decodes a stream of CBOR bytes into JSON.
Usage:
csd [-in inputFile] [-out outputFile] [-compress] [-follow]
Use -compress if the input is a zlib compressed data - csd will uncompress and decode
Use -follow to continually monitor inputFile for new bytes and decode as they are written to the file
Run csd -h for a list of supported options and usage.
If -in is omitted, csd reads from stdin.
If -out is omitted, csd writes to stdout.
Suppose CBOR encoded data is present in file cbor.log, you could do one of these methods to convert to JSON using csd:
Input from file, output to stdout :
$ csd -in cbor.log
{"level":"error","Fault":41650,"time":"2018-03-31T07:17:19-07:00","message":"TCA:"}
{"level":"error","Fault":41654,"time":"2018-03-31T07:17:19-07:00","message":"TCA:"}
...
Input from stdin, output to stdout
$ cat cbor.log | csd
{"level":"error","Fault":41650,"time":"2018-03-31T07:17:19-07:00","message":"TCA:"}
{"level":"error","Fault":41654,"time":"2018-03-31T07:17:19-07:00","message":"TCA:"}
...
Input from file, output to file
$ csd -in cbor.log -out json.txt
$ cat json.txt
{"level":"error","Fault":41650,"time":"2018-03-31T07:17:19-07:00","message":"TCA:"}
{"level":"error","Fault":41654,"time":"2018-03-31T07:17:19-07:00","message":"TCA:"}
...
The easiest way to install is to run go get -u github.com/toravir/csd. You could also manually
git clone the repository and do a go build.
For documentation of APIs used to decode, see: https://godoc.org/github.com/toravir/csd/libs/
The input is expected to be CBOR data (either zlib-compressed or not). It is NOT possible to detect JSON (text) output reliably since binary format spans over JSON character set also.
