ProcBlocks Overview

ProcBlocks (Processor Blocks) is a declarative YAML-based Markup Language for defining image-processing pipelines as a stack of processor blocks—much like HTML describes webpage structure. Instead of writing custom code for each edit, you author Block Sequences.

Key concepts:

• YAML block syntax: Each top-level list item defines an assign, processor, or job block.
• Inputs & Outputs: Blocks read from and write to a virtual filesystem.
• Virtual Filesystem: The filesystem mounts server memory, account stores, local and network shares, as simple paths.
• Processors: Files are processed through parameterized processor blocks and written back to the filesystem.
• Advanced Parsing: Use inline methods ({width:source}) and expressions ([[10+5]]) to access metadata, compute values, or branch logic.
• Nested Job Definitions: Embed entire job definitions inside one another for modular workflows.
• User Input: Define custom UI elements to gather parameters at runtime.

Why ProcBlocks?

• Readability: Declarative YAML + named blocks makes pipelines easy to scan and maintain.
• Extensibility: Add or nest custom processors without rewriting core logic.
• Consistency: Built-in validation, filtering, and overrides ensure predictable results everywhere.
