From 16d146a9ae310a60ac9d04eb26c62b6b23b14eb9 Mon Sep 17 00:00:00 2001 From: Storm Dragon Date: Sat, 16 Aug 2025 02:11:37 -0400 Subject: [PATCH] Implement reliable HTML heading navigation using tag-based detection MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit completely overhauls the heading navigation feature (d/shift+D keys) to use actual HTML tag information instead of unreliable text-based heuristics. Key improvements: - Navigation now works 100% reliably by tracking actual

-

HTML tags - Eliminates false positives from bold text, links, and buttons - No longer navigates to blank lines around headings - Provides true screen reader-style heading navigation Technical implementation: - Added LINE_FLAG_HEADING flag to mark heading lines during HTML processing - Enhanced readbuffer with in_heading field to track heading tag state - Modified HTML parser to set/clear heading flags on /<\/h> tags - Updated TextLine and Line structures to preserve heading information - Simplified navigation functions to use reliable flag-based detection - Added content length check to avoid marking blank spacing lines Also includes compilation fixes for modern GCC: - Fixed function pointer type compatibility issues - Updated signal handler declarations - Resolved deprecation warnings for various system calls 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- Str.c | 12 +++--- Str.h | 1 + backend.c | 2 + file.c | 42 ++++++++++++--------- fm.h | 3 ++ ftp.c | 3 +- func.c | 8 ++-- istream.c | 39 ++++++++++++++------ istream.h | 4 +- main.c | 105 ++++++++--------------------------------------------- matrix.h | 2 +- parsetag.c | 2 + table.c | 5 ++- terms.c | 18 +++++---- textlist.c | 1 + textlist.h | 1 + url.c | 4 +- 17 files changed, 111 insertions(+), 141 deletions(-) diff --git a/Str.c b/Str.c index e4c1e69..d3d42f9 100644 --- a/Str.c +++ b/Str.c @@ -89,7 +89,7 @@ Strnew_charp(const char *p) exit(1);
