shimexe-core

Core library for shimexe - a modern, cross-platform executable shim manager with environment variable expansion and TOML configuration support.

Overview

shimexe-core provides the foundational functionality for creating and managing executable shims. It offers a flexible and extensible architecture for building shim management tools.

Features

• Cross-platform support: Works on Windows, macOS, and Linux
• TOML configuration: Easy-to-read and write configuration format
• Environment variable expansion: Dynamic path resolution with shell-style variable expansion
• Template engine: Flexible argument and environment variable templating
• Auto-update support: Built-in mechanisms for keeping shims up-to-date
• Extensible architecture: Trait-based design for customization
• Async support: Built with async/await for better performance

Core Components

ShimConfig

Manages shim configuration including target executable paths, arguments, and environment variables.

ShimRunner

Executes shims with proper argument handling and environment setup.

TemplateEngine

Provides variable expansion and templating for dynamic configuration.

ShimUpdater

Handles automatic updates for shim configurations and target executables.

Usage

Add this to your Cargo.toml:

[dependencies]
shimexe-core = "0.1.0"

Basic Example

use shimexe_core::prelude::*;

#[tokio::main]
async fn main() -> Result<()> {
    // Load shim configuration
    let config = ShimConfig::from_file("path/to/shim.toml")?;
    
    // Create and run shim
    let runner = ShimRunner::new(config);
    let exit_code = runner.run(&["arg1", "arg2"]).await?;
    
    std::process::exit(exit_code);
}

Configuration Example

# shim.toml
[shim]
target = "${HOME}/bin/my-tool"
args = ["--config", "${CONFIG_DIR}/config.yaml"]

[shim.env]
PATH = "${PATH}:${HOME}/bin"
MY_TOOL_HOME = "${HOME}/.my-tool"

[shim.metadata]
name = "my-tool"
version = "1.0.0"
description = "My awesome tool"

Advanced Usage

use shimexe_core::*;

// Custom shim runner with additional features
struct CustomRunner {
    inner: ShimRunner,
}

impl CustomizableShimRunner for CustomRunner {
    fn pre_run(&mut self, args: &[String]) -> Result<()> {
        // Custom pre-execution logic
        println!("Running with args: {:?}", args);
        Ok(())
    }
    
    fn post_run(&mut self, exit_code: i32) -> Result<()> {
        // Custom post-execution logic
        println!("Finished with exit code: {}", exit_code);
        Ok(())
    }
}
