From f75a47fe766b3c7064a3bcf1fa06cc266fa518b7 Mon Sep 17 00:00:00 2001 From: Andy Date: Mon, 11 Aug 2025 18:19:53 +0800 Subject: [PATCH] Feature-gate runtime server; migrate MCP API; improve DOCX fallbacks Gate runtime server behind `runtime-server` feature and align tool interfaces with latest `mcp_core` response types. Add safer DOCX->PDF fallbacks (dotext reader, inline comments/notes/cross-refs) and clarify crate imports (`image`, `lopdf`) to reduce conflicts; minor PDF utilities cleanup. --- Cargo.toml | 4 +++ src/advanced_docx.rs | 82 ++++++++++--------------------------------- src/converter.rs | 29 +++++++-------- src/docx_tools.rs | 23 +++++++----- src/main.rs | 37 ++++++++++--------- src/pure_converter.rs | 6 ++-- 6 files changed, 76 insertions(+), 105 deletions(-) diff --git a/Cargo.toml b/Cargo.toml index 43bd9b1..3478207 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -57,6 +57,9 @@ pulldown-cmark = "0.12" # Markdown parsing html5ever = "0.29" # HTML parsing comrak = "0.28" # CommonMark parsing +# Text extraction from DOCX +dotext = "0.1" + # Template rendering (pure Rust) handlebars = "6.0" # Template engine tera = { version = "1.20", optional = true } @@ -96,6 +99,7 @@ wkhtmltopdf = { version = "0.4", optional = true } [features] default = ["embedded-fonts", "pure-rust-pdf"] +runtime-server = [] embedded-fonts = [] pure-rust-pdf = [] external-tools = ["headless_chrome", "wkhtmltopdf"] diff --git a/src/advanced_docx.rs b/src/advanced_docx.rs index 7d193de..1e2f140 100644 --- a/src/advanced_docx.rs +++ b/src/advanced_docx.rs @@ -86,24 +86,9 @@ impl AdvancedDocxHandler { let width_emu = width_px * 9525;
