epcis-cli-0.2.0 is not a library.

`epcis-cli`

A command line utility for working with GS1 EPCIS 2.0 events. It supports generating canonical pre-hashes, final SHA-256 hashes, and translating GS1 visibility keys between EPC URN and Digital Link formats.

Installation

To compile and install the CLI tool locally from the workspace:

cargo install --path .

Usage

Usage: epcis-cli [OPTIONS] [FILE]

Arguments:
  [FILE]  File path to parse (use "-" or omit to read from standard input)

Options:
  -p, --prehash          Print the canonical pre-hash string instead of the hash URN
  -e, --enforce-format   Force input format: "json" or "xml"
  -t, --translate <KEY>  Translate a GS1 key between EPC URN and Digital Link formats
  -l, --prefix-len <LEN> The company prefix length to use for Digital Link translation [default: 7]
      --cbv-1-2          Use legacy CBV 1.2 rules (omits user extensions from hashing)
      --base-url <URL>   The base URL to use when translating URN to Digital Link [default: https://id.gs1.org]
  -h, --help             Print help
  -V, --version          Print version

Examples

1. Translate GS1 Identifiers

URN to Digital Link:

epcis-cli --translate "urn:epc:id:sgtin:4012345.098765.12345"
# Output: https://id.gs1.org/01/04012345987652/21/12345

Digital Link to URN (using default company prefix length of 7):

epcis-cli --translate "https://id.gs1.org/01/04012345987652/21/12345"
# Output: urn:epc:id:sgtin:4012345.098765.12345

Digital Link to URN (specifying custom company prefix length of 10):

epcis-cli -l 10 --translate "https://id.gs1.org/01/04012345678904/21/12345"
# Output: urn:epc:id:sgtin:4012345678.90.12345

2. Generate Canonical Pre-hashes

From JSON-LD Document:
```
epcis-cli -p document.jsonld
```
From XML Document piped through Stdin:
```
cat document.xml | epcis-cli -p
```

3. Generate SHA-256 Hash URNs

From any EPCIS document:

epcis-cli document.xml
# Output URN: ni:///sha-256;...
