Configuration
Configuration lives in archledger.toml.
Important sections
[source]controls the canonical source dialect and extensions.[ids]controls ledger ID prefix/width and optional ID segment behavior.[build]controls default output behavior and converter selection.[tracking]controls workspace snapshots and change detection.[arc42]controls document metadata defaults.[skill]points agents at the repository skill file.
Example
config_version = 7
archledger_dir = ".archledger"
[ids]
prefix = "al"
width = 4
segment_mode = "none"
default_segment = "content"
[ids.segment_map]
section = "content"
requirement = "content"
risk = "risk"
[source]
format = "markdown"
section_extension = ".md"
record_extension = ".md"
schema_version = 2
[build]
default_output = "architecture.md"
default_format = "markdown"
default_output_dir = "build"
converter = "auto"
[tracking]
enabled = true
state_file = "source-state.json"
scanner = "auto"
[build].default_output_dir is relative to the directory containing
archledger.toml or .archledger.toml.
source-state.json stores SHA-256 content hashes only for files. It does not
persist mtimes or file sizes. Directory hashes are derived from file hashes.
The archive path is fixed at <archledger_dir>/archive and is used by
archledger archive and archledger doctor --repair to preserve
ledger-number history without renumbering.
ID segment modes
segment_mode = "none"IDs use
<prefix>_<number>(for exampleal_0013).segment_mode = "type"IDs use
<prefix>_<segment>_<number>(for exampleal_risk_0014).
Segment resolution order is deterministic:
id_segmentmetadata on the record[ids.segment_map]by recordtypedefault_segment
The numeric ledger sequence remains global across all segments.
Per-output overrides
Use [build.outputs.<format>] for format-specific settings. Supported keys are
tool, pdf_engine, reference_docx, and enabled.
