Dumping packages' signatures as JSON¤
Griffe can be used to load packages' signatures and output them as JSON on the standard output or in writable files.
Pass the names of packages to the griffe dump
command:
$ griffe dump httpx fastapi
{
"httpx": {
"name": "httpx",
...
},
"fastapi": {
"name": "fastapi",
...
}
}
It will output a JSON-serialized version of the packages' signatures.
Try it out on Griffe itself:
$ griffe dump griffe
{
"griffe": {
"name": "griffe",
...
}
}
To output in a file instead of standard output, use the --output
or -o
option:
$ griffe dump griffe -o griffe.json
If you load multiple packages' signatures, you can dump each in its own file with a templated filepath:
$ griffe dump griffe -o './dumps/{package}.json'
By default, Griffe will search in sys.path
, so if you installed it through pipx, there are few chances it will find your packages. To explicitly specify search paths, use the -s, --search <PATH>
option. You can use it multiple times. You can also add the search paths to the PYTHONPATH
environment variable. If Griffe can't find the packages, it will fail with a ModuleNotFoundError
.
