Name: "tvx",

Description: `tvx is a tool for extracting and executing test vectors. It has four subcommands.
|
|
|
|
tvx extract extracts a test vector from a live network. It requires access to
|
|
a Filecoin client that exposes the standard JSON-RPC API endpoint. Only
|
|
message class test vectors are supported at this time.
|
|
|
|
tvx exec executes test vectors against Lotus. Either you can supply one in a
|
|
file, or many as an ndjson stdin stream.
|
|
|
|
tvx extract-many performs a batch extraction of many messages, supplied in a
|
|
CSV file. Refer to the help of that subcommand for more info.
|
|
|
|
tvx simulate takes a raw message and simulates it on top of the supplied
|
|
epoch, reporting the result on stderr and writing a test vector on stdout
|
|
or into the specified file.
|
|
|
|
SETTING THE JSON-RPC API ENDPOINT
|
|
|
|
You can set the JSON-RPC API endpoint through one of the following methods.
|
|
|
|
1. Directly set the API endpoint on the FULLNODE_API_INFO env variable.
|
|
The format is [token]:multiaddr, where token is optional for commands not
|
|
accessing privileged operations.
|
|
|
|
2. If you're running tvx against a local Lotus client, you can set the REPO
|
|
env variable to have the API endpoint and token extracted from the repo.
|
|
Alternatively, you can pass the --repo CLI flag.
|
|
|
|
3. Rely on the default fallback, which inspects ~/.lotus and extracts the
|
|
API endpoint string if the location is a Lotus repo.
|
|
|
|
tvx will apply these methods in the same order of precedence they're listed.
