vimvar

vimvar-rs: Library to read neovim/vim variables from Rust

Installation

# Cargo.toml
[dependencies]
vimvar = "0.3"

Usage

// Loads g:my_global_var from default vimrc, returning None if it does not
// exist, and casting to type String from the default serde_json::Value
//
// Only fails unwrap if neovim/vim fails to run or type fails to cast
let var: Option<String> = vimvar::load_typed_global_var("my_global_var").unwrap();
println!("Loaded g:my_global_var = {:?}", var);

For more a more explicit example

use vimvar::*;
use serde_json::json;

// Load explicitly a buffer variable (b:my_buffer_var) using neovim
let var = VimVar::new(Cmd::NeoVim, Scope::Buffer, "my_buffer_var");

// Load the variable using a different config file versus the standard one
let value = var.load_with_config("path/to/config.vim", false).expect("Failed to load variable");
assert_eq!(value, Some(json!("some buffer value")));
