PRDoc
prdoc
is a tool designed to help generating, checking and loading .prdoc
files.
.prdoc
files are YAML files adhering to defined JSON schema and helping with
code change documentation.
While platform like Github allow a simple description for a Pull Request (PR), this is limited to a title, description and some labels.
The description of a PR itself is often used to describe the change but not document it in a structured fashion. A sample schema can be found here: prdoc_schema_user.json but each repository is free to define its own JSON Schema.
Features
-
generate command to create new PRDoc files
-
scan command: to quickly scan for PRDOc files in a folder
-
check command: to check one or more PRDOc files
-
load command: to load one or more PRDoc files
Install
cargo install prdoc
Alternatively, you may use a the container image if you prefer not installing anything on your system. See the Containers section for more details on containers.
Philosophy
Configuration, cli flags and environment variables
In order to provide a simple and uniform behavior in a repo, prdoc
will search for a local configuration file.
The configuration file is a YAML file named .prdoc.toml
or prdoc.toml
and located in the root of the repo.
The configuration file can alternatively be passed via ENV (PRDOC_CONFIG
) or cli flag (-c
|--config
).
ENV and cli flags have precedence over the local configuration file.
Simple to use
While most commands supports options, they are designed to be simple to use and require a minimal amount of user input
when either a config or an .env
file is present.
Authoring a PRDoc
Without tooling
No tooling but a text editor is required to author a new PRDoc. You may simply copy the template from your repo. The template is defined in the ???:
grep template *prdoc.toml
You then need to save the file as pr_NNNN.prdoc
(where NNN
is the PR number) in the repo’s prdoc folder.
This folder is also defined in the config (./prdoc
is the default`):
grep output *prdoc.toml
Using the prdoc
cli
You will however find it more convenient to install and use the prddoc
cli and just run:
prdoc generate 9999
After editing the PRDoc file, you may check whether is adheres to the schema using:
prdoc check -n 1226
Using VSCode
See the Schemas chapter to learn how to configure VSCode to recognize and check PRDoc files.
YAML Anchors
You may use YAML anchors as demonstrated below.
# Schema: Parity PR Documentation Schema (prdoc)
title: Foobar
doc:
- audience: Runtime User
description: &desc |
Sunt voluptate ad duis consequat ea in dolore non adipisicing incididunt
ullamco enim qui enim.
- audience: Validator
description: *desc
migrations:
db: []
runtime: []
crates: []
host_functions: []
Config
Using a configuration file makes it easier for all users as they will be able to omit some of the required flags when
using the prdoc
.
Config file name and location
The config will be found if located at the root of the repo and named either:
prdoc.toml
.prdoc.toml
Alternatively, it can be defined as an ENV named PRDOC_CONFIG
and contain the path of the config, relative to the
repository’s root.
Content
version = 1
schema = "tests/data/sample_schema.json"
output_dir = "/tmp/prdoc"
prdoc_folders = ["tests/data/all", "tests/data/some"]
template = "template.prdoc"
Paths
In order to make it easier to use, prdoc
and its configuration always refer to the root of the repository.
It means you can pass either absolute paths or relative ones but relatives ones are based on the root of the repo and not the current working directory.
This allows users to use commands such as:
prdoc check -n 1234
# instead of:
# prdoc check -n 1234 -d ../../folder/where/prdoc_files/are/stored
Or also:
prdoc generate 1234
# instead of;
# prdoc generate 1234 -o ../../folder/where/prdoc_files/are/stored
Schemas
PR Doc
The documentation for PRs comes as a file with the extension .prdoc
.
This is essentially a yaml
file and the extension helps using the right JSON schema to validate the file.
In VScode, open your user settings and ensure you have the following section:
You first need to tell VScode that .prdoc files are YAML files:
"files.associations": {
"*.prdoc": "yaml",
},
You then need to point to the right schemas:
"yaml.schemas": {
[...other schemas...]
"/path/to/polkadot-sdk/prdoc/schema_user.json": "*polkadot-sdk*/**/*.prdoc",
"/path/to/subxt/prdoc/schema_user.json": "*subxt*/**/*.prdoc"
},
You need to restart/reload VSCode after those changes for the new settings to be picked up.
Should you initially have created the file with another extension such as .txt
, make sure to change the format to
YAML
in the VSCode status bar and the right schema should then be picked up.
Usage
prdoc is a utility to generate, check and load PRDoc files.

Containers
If you prefer not having to install Rust & Cargo and have Podman or Docker installed, you may prefer to run a containerized
version of prdoc
. This chapter explains how to proceed.
prdoc is designed to work at the repository level and you need to mount your repo as /repo
into the prdoc container.
podman run --rm -it -v $PWD:/repo paritytech/prdoc --help
ENGINE=podman
DOC_PATH="$PWD/tests/data/some"
$ENGINE run --rm -it -v $DOC_PATH:/repo paritytech/prdoc --help
$ENGINE run --rm -it -v $DOC_PATH:/repo paritytech/prdoc scan --all
$ENGINE run --rm -it -v $DOC_PATH:/repo paritytech/prdoc check
$ENGINE run --rm -it -v $DOC_PATH:/repo paritytech/prdoc load
The container image is working by default in /repo
so it makes it simpler if you mount your repo there as shown
above.
Run
podman run --rm -it -v $PWD:/repo paritytech/prdoc --help
ENGINE=podman
DOC_PATH="$PWD/tests/data/some"
$ENGINE run --rm -it -v $DOC_PATH:/repo paritytech/prdoc --help
$ENGINE run --rm -it -v $DOC_PATH:/repo paritytech/prdoc scan --all
$ENGINE run --rm -it -v $DOC_PATH:/repo paritytech/prdoc check
$ENGINE run --rm -it -v $DOC_PATH:/repo paritytech/prdoc load
The container image is working by default in /repo
so it makes it simpler if you mount your repo there as shown
above.
Commands can end up quite lengthy so you may like to set an alias:
alias prdoc='podman run --rm -it -v $PWD:/repo paritytech/prdoc'
After setting this alias, you may use prdoc
by simply invoking the prdoc
command:
prdoc --version
This is out of the scope of this documentation but note that you can just invoke prdoc check
and expect it to work in
your repo as long as it contains a valid configuration file and schema. Check out the ??? chapter for more
details.
Build
You can pull the container image from paritytech
/prdoc
or build you own:
podman build -t prdoc .
