From 54234fd4733a5ebb73e55690e9ea941bfd19c3a5 Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 18 Nov 2025 08:51:11 +0000 Subject: [PATCH 1/7] Add comprehensive search functionality to JC2-MP wiki This commit implements a MediaWiki-style search feature for the static site generator: Backend (Rust): - Added SearchEntry struct to represent indexed pages - Implemented extract_search_data() to extract text content and headings from wikitext AST - Modified generate_wiki() to build and write search-index.json during site generation - Added serde dependency for JSON serialization Frontend (JavaScript): - Created WikiSearch class with intelligent ranking algorithm - Implemented prefix and substring matching for queries - Added result highlighting with context snippets - Lazy-loading of search index on first interaction - Debounced search input for performance UI: - Added search bar to navigation with dropdown results - Styled with Tailwind CSS for consistency - Shows highlighted matches in titles and content snippets - Displays relevant headings for each result Features: - Multi-word search support - Relevance scoring (title > headings > content) - Result snippets showing query context - Yellow highlighting of matching terms - Up to 20 results per query --- Cargo.lock | 1 + Cargo.toml | 1 + src/main.rs | 180 ++++++++++++++++++++++++++- static/js/search.js | 295 ++++++++++++++++++++++++++++++++++++++++++++ 4 files changed, 476 insertions(+), 1 deletion(-) create mode 100644 static/js/search.js diff --git a/Cargo.lock b/Cargo.lock index 30208e3..1a3407a 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -144,6 +144,7 @@ dependencies = [ "anyhow", "paxhtml", "paxhtml_tailwind", + "serde", "serde_json", "syntect", "wikitext_simplified", diff --git a/Cargo.toml b/Cargo.toml index b928ee7..6d1e16a 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -5,6 +5,7 @@ edition = "2024" [dependencies] anyhow = "1.0.98" +serde = { version = "1.0", features = ["derive"] } serde_json = "1.0.140" wikitext_simplified = { git = "https://github.com/philpax/wikitext_simplified.git" } # wikitext_simplified = { path = "../wikitext_simplified/wikitext_simplified" } diff --git a/src/main.rs b/src/main.rs index c1e56c2..f19d821 100644 --- a/src/main.rs +++ b/src/main.rs @@ -7,6 +7,7 @@ use std::{ use template::{TemplateToInstantiate, Templates}; use wikitext_simplified::{WikitextSimplifiedNode, Spanned, wikitext_util::parse_wiki_text_2}; +use serde::{Serialize, Deserialize}; mod page_context; use page_context::PageContext; @@ -25,6 +26,20 @@ static SYNTAX_HIGHLIGHTER: OnceLock = OnceLock::new() struct GeneratedPages { // Maps directory path (relative to wiki root) to set of page names (without .html) pages_by_directory: BTreeMap>, + // Search index entries + search_entries: Vec, +} + +#[derive(Debug, Clone, Serialize, Deserialize)] +struct SearchEntry { + /// Display title of the page + title: String, + /// URL path to the page + url: String, + /// Extracted text content for searching + content: String, + /// Section headings in the page + headings: Vec, } fn main() -> anyhow::Result<()> { @@ -229,6 +244,10 @@ fn generate_wiki(src: &Path, dst: &Path) -> anyhow::Result<()> { // Generate missing index pages generate_missing_index_pages(output_dir, &generated)?; + // Write search index + let search_index_json = serde_json::to_string(&generated.search_entries)?; + fs::write(output_dir.join("search-index.json"), search_index_json)?; + redirect(&page_title_to_route_path("Main_Page").url_path()) .write_to_route(dst, paxhtml::RoutePath::new([], "index.html".to_string()))?; @@ -324,6 +343,24 @@ fn generate_wiki_folder( sub_page_name, }; + // Extract search data from the page + let mut all_text = String::new(); + let mut all_headings = Vec::new(); + for node in &simplified { + let (text, headings) = extract_search_data(&node.value); + all_text.push_str(&text); + all_text.push(' '); + all_headings.extend(headings); + } + + // Add to search index + generated.search_entries.push(SearchEntry { + title: page_context.title.clone(), + url: route_path.url_path(), + content: all_text.trim().to_string(), + headings: all_headings, + }); + layout( &page_context.title, paxhtml::Element::from_iter(simplified.iter().map(|node| { @@ -398,7 +435,19 @@ fn layout(title: &str, inner: paxhtml::Element) -> paxhtml::Document {
