"""

|
The purpose of this script is to output the version of the libwasm library that is
|
|
specified in the go.mod file in the wasm module.
|
|
|
|
This should be passed as a build argument to the Dockerfile to determine which static library should
|
|
be added.

usage: get-libwasm-version.py [-h] [--get-version | --no-get-version | --get-checksum | --no-get-checksum] [--wasm-library WASM_LIBRARY] [--wasm-go-mod-path WASM_GO_MOD_PATH]
|
|
|
|
Wasm dockerfile utility
|
|
|
|
options:
|
|
-h, --help show this help message and exit
|
|
--get-version, --no-get-version
|
|
Get the current version of CosmWasm specified in wasm module.
|
|
--get-checksum, --no-get-checksum
|
|
Returns the checksum of the libwasm library for the provided version.
|
|
--wasm-library WASM_LIBRARY
|
|
The name of the library to return the checksum for.
|
|
--wasm-go-mod-path WASM_GO_MOD_PATH
|
|
