Compile and render schema-validated configuration data.
Project description
datazen (1.13.0)
Compile and render schema-validated configuration data.
Good software is composable and configurable, but the complexity of managing configuration data scales with its complexity.
This package simplifies data curation and partitioning for uses in rendering templates, or just rendering final sets of serialized data.

Usage
$ ./venv3.7/bin/dz -h
usage: dz [-h] [--version] [-v] [-C DIR] [-m MANIFEST] [-c] [--sync] [-d]
[targets [targets ...]]
Compile and render schema-validated configuration data.
positional arguments:
targets target(s) to execute
optional arguments:
-h, --help show this help message and exit
--version show program's version number and exit
-v, --verbose set to increase logging verbosity
-C DIR, --dir DIR execute from a specific directory
-m MANIFEST, --manifest MANIFEST
manifest to execute tasks from (default:
'manifest.yaml')
-c, --clean clean the manifest's cache and exit
--sync sync the manifest's cache (write-through) with the
state of the file system before execution
-d, --describe describe the manifest's cache and exit
Manifest Schema
A manifest is provided to datazen
to establish the set of targets
that should be executed based on defaults or the command-line invocation.
Manifest Includes
Include additional files to build the final, root manifest with. This same schema applies to included files.
includes: paths
Output Directory
Override the default output directory (i.e. datazen-out
).
output_dir:
type: string
Cache Directory
Override the default cache directory (i.e. .manifest_cache
).
cache_dir:
type: string
Global Loads
For each of these keys, add paths that should be loaded globally.
configs: paths
schemas: paths
schema_types: paths
templates: paths
variables: paths
Manifest Parameters
Manifests themselves are Jinja templates that are rendered with the data contained in this key.
params:
type: dict
Default Target
The target to execute by default if none is provided.
default_target:
type: string
Compiles
Target definitions for compilation tasks.
compiles:
type: list

merge_deps:

Commands
Target definitions for command-line command tasks.

force:

Renders
Target definitions for render tasks. Renders can create output files based on Jinja templates, or just String data to be used as a dependency for another task.

templates: paths
children: deps

no_dynamic_fingerprint:
type: boolean
no_file:
type: boolean
indent:
type: integer
template_dependencies:
type: list
schema:
type: string
Groups
Target definitions for group tasks. Groups declare a set of dependencies and nothing else. Groups can be used as dependencies for any other target.
groups:
type: list
schema:
type: dict
schema:
name:
type: string
dependencies: deps
Manifest Schema Types
These items may appear in the manifest schema.
deps
Dependencies are lists of Strings.
They should be formatted as (compiles,renders,...)-target
.
type: list
schema:
type: string
paths
Paths are lists of Strings and can use /
or \\
as delimeters.
Paths are relative to the directory that a manifest file is in, but for
manifest includes, all "loaded" directories are relative to the root
manifest's directory. Paths can also be absolute.
