miniconf-pest-parser

MiniConf is a plain-text configuration format with sections and key = value pairs. This crate provides a PEG grammar written for pest and the Rust structures used in the project.

How it works

• Sections are declared as [section_name].
• Keys use ASCII identifiers and are assigned with key = value.
• Comments start with # and continue to the end of the line.
• Whitespace (spaces, tabs, newlines) is ignored outside of tokens.

Supported values:

• Strings in double quotes with simple escapes (\", \n, \t).
• Decimal numbers, optionally signed.
• Booleans (true, false).
• null.
• Arrays like [value, value].
• Objects like {key: value}.

All parsed data lands in Document { sections: HashMap<String, HashMap<String, Value>> }, so you can read data as doc.sections["database"]["port"].

Sample

# Project
title = "Project Alpha"
version = 1.0
flags = { debug: true }

[database]
host = "localhost"
port = 5432
tags = ["primary", "ro"]
