Configurations

Many of the chifra commands allow you to customize their behaviour through configuration files and/or environment variables. These options are documented here.

Environment variables

Each command-line option may be overridden by exporting an environment variable in your shell prior to running a chifra command.

The name of those environment variables is as follows:

The environment variable beings with TB_
The environment variable is ALL_UPPER_CASE
The environment variable name removes underbars from the item_name (item_name becomes ITEMNAME)
The environment variable name starts with the group the item belongs to

For example: TB_GROUP_ITEMNAME.

A more concrete example might be:

export TB_SETTINGS_RPCPROVIDER=http://localhost:9876
chifra blocks 100

which would cause chifra to use an alternate rpcProvider without having to edit the configuration file.

This feature comes in handy when build shell scripts to automate various tasks with chifra.

Where are configs stored?

The configuration files for chifra are stored in the operating system specific locations in the TrueBlocks folder.

Separate files

A single global configuration, called trueBlocks.toml, which stores all the configuration items, is located at the root of the configuration folder.

The remained of this documentation is incorrect. See the configuration file itself or the source code for more information.

Note: As of version 2.5.2, this is no longer true.

In addition, each individual tool may have its own configuration file with items peculuar to that tool. If a configuration item is found in a particular file, it applies only to that tool.

If, however, one of the items documented below under trueBlocks.toml is found in a tool’s individual config, it will override that value for that tool only.

For historical reasons, the configuration files are names based on old tool names. Please see the table below for the name of each tool’s config file.

Multichain

If you’re running against mutliple chains, you may place any of these files in the root of the chain’s configuration folder, and the values found there will replace any values found at the top level. In this way, you may configure all chains for certain values, but customize your configuration per chain.
