# Raiden Config File¶

Raiden supports reading configuration parameters from a configuration file.

## Location¶

The default location is <datadir>/config.toml (where datadir defaults to ~/.raiden).

It is possible to override the datadir in the config file but please be aware that at that point the config file will already have been loaded from the default location and therefore won’t be re-read from the ‘new’ datadir.

## Precedence¶

The precedence order in which configuration option values are applied is as follows (high to low):

1. Option given on the command line

2. Option read from the config file

3. Option default value (as seen in the output of raiden --help)

## Format¶

The config file uses the TOML format.

Option names may be quoted unless they contain punctuation in which case they must be. Values except numbers must always be quoted. Both single or double quotes are acceptable.

Lines starting with a # are comments.

## Parameter Naming¶

All parameters that can be given as command line options are also settable in the config file. The name corresponds to the long option name without the leading double dash (--). For example the CLI option --password-file would be called password-file inside the config file.

The only option deviating from this scheme is the logging configuration which is explained below.

## Logging Configuration¶

Raiden allows configuration of the logging system using a concise syntax on the command line. Inside the configuration file this is split out into a somewhat more expanded syntax.

The logging configuration is placed inside a section called [log-config] which each following lines key representing the logger name and the value the log level.

Example:

# CLI:
--log-config ':debug,raiden.network:info'

# Config file equivalent:
[log-config]
"" = "debug"
"raiden.network" = "info"
