The best choice depends on the specific requirements for accuracy of rendering, resource constraints, and deployment environment. 95 | 96 | ## Feature Flags 97 | 98 | 1. **mcp_experimental**: 99 | - Enables the experimental MCP (Model Context Protocol) integration 100 | - When enabled, adds MCP server and client functionality 101 | - Disabled by default to keep the core tool lightweight 102 | - Can be enabled with `cargo build --features mcp_experimental` 103 | -------------------------------------------------------------------------------- /CHANGELOG.md: -------------------------------------------------------------------------------- 1 | # Changelog 2 | 3 | ## [Unreleased] 4 | 5 | ### Added 6 | - Experimental MCP (Model Context Protocol) integration 7 | - New feature flag `mcp_experimental` to enable/disable MCP functionality at compile time 8 | - Documentation for MCP experimental features in README.md 9 | - MCP server and client functionality (when compiled with the feature flag) 10 | 11 | ### Changed 12 | - MCP-related command line options are now marked as experimental 13 | - MCP-related code is now conditionally compiled only when the feature flag is enabled 14 | - Updated documentation to reflect the experimental status of MCP features 15 | 16 | ### Developer Notes 17 | - MCP tests are now conditionally compiled with the feature flag 18 | - Added feature flag documentation in AmazonQ.md 19 | -------------------------------------------------------------------------------- /Cargo.toml: -------------------------------------------------------------------------------- 1 | [package] 2 | name = "weblook" 3 | version = "0.1.0" 4 | edition = "2024" 5 | authors = ["Kelsea Blackwell"] 6 | description = "A command-line tool for capturing screenshots and recordings of web pages" 7 | license = "GPL-3.0" 8 | repository = "https://github.com/TrippingKelsea/weblookrs" 9 | readme = "README.md" 10 | keywords = ["screenshot", "web", "capture", "gif", "recording"] 11 | categories = ["command-line-utilities", "multimedia"] 12 | 13 | [lib] 14 | name = "weblook" 15 | path = "src/lib.rs" 16 | 17 | [[bin]] 18 | name = "weblook" 19 | path = "src/main.rs" 20 | 21 | [features] 22 | default = [] 23 | # Experimental MCP (Model Context Protocol) support 24 | mcp_experimental = [] 25 | 26 | [dependencies] 27 | anyhow = "1.0.98" 28 | atty = "0.2.14" 29 | base64 = "0.21.7" 30 | chrono = "0.4.40" 31 | clap = { version = "4.5.36", features = ["derive"] } 32 | colored = "3.0.0" 33 | futures = "0.3.31" 34 | gif = "0.13.1" 35 | image = "0.25.6" 36 | indicatif = "0.17.11" 37 | # mcp-sdk = { git = "https://github.com/modelcontextprotocol/rust-sdk" } 38 | rand = "0.9.0" 39 | serde = { version = "1.0.197", features = ["derive"] } 40 | serde_json = "1.0.114" 41 | tempfile = "3.19.1" 42 | thirtyfour = "0.35.0" 43 | tokio = { version = "1.44.2", features = ["full"] } 44 | url = "2.5.4" 45 | webp = "0.3.0" 46 | 47 | [dev-dependencies] 48 | mockito = "1.4.0" 49 | -------------------------------------------------------------------------------- /LICENSE.md: -------------------------------------------------------------------------------- 1 | # GNU GENERAL PUBLIC LICENSE 2 | 3 | Version 3, 29 June 2007 4 | 5 | Copyright (C) 2007 Free Software Foundation, Inc. 6 | 7 | Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. 8 | 9 | ## Preamble 10 | 11 | The GNU General Public License is a free, copyleft license for software and other kinds of works. 12 | 13 | The licenses for most software and other practical works are designed to take away your freedom to share and change the works.
