solana-cli-config 1.14.15

Loading and saving the Solana CLI configuration file. The configuration file used by the Solana CLI includes information about the RPC node to connect to, the path to the user's signing source, and more. Other software than the Solana CLI may wish to access the same configuration and signer. The default path to the configuration file can be retrieved from [`CONFIG_FILE`], which is a [lazy_static] of `Option`, the value of which is > `~/.config/solana/cli/config.yml` [`CONFIG_FILE`]: struct@CONFIG_FILE [lazy_static]: https://docs.rs/lazy_static `CONFIG_FILE` will only be `None` if it is unable to identify the user's home directory, which should not happen under typical OS environments. The CLI configuration is defined by the [`Config`] struct, and its value is loaded with [`Config::load`] and saved with [`Config::save`]. Two important fields of `Config` are - [`json_rpc_url`], the URL to pass to `solana_client::rpc_client::RpcClient`. - [`keypair_path`], a signing source, which may be a keypair file, but may also represent several other types of signers, as described in the documentation for `solana_clap_utils::keypair::signer_from_path`. [`json_rpc_url`]: Config::json_rpc_url [`keypair_path`]: Config::keypair_path # Examples Loading and saving the configuration. Note that this uses the [anyhow] crate for error handling. [anyhow]: https://docs.rs/anyhow ```no_run use anyhow::anyhow; use solana_cli_config::{CONFIG_FILE, Config}; let config_file = solana_cli_config::CONFIG_FILE.as_ref() .ok_or_else(|| anyhow!("unable to get config file path"))?; let mut cli_config = Config::load(&config_file)?; // Set the RPC URL to devnet cli_config.json_rpc_url = "https://api.devnet.solana.com".to_string(); cli_config.save(&config_file)?; # Ok::<(), anyhow::Error>(()) ```
