Changes: * Two new colour constants — _DIFF_BG_ADD_HL / _DIFF_BG_DEL_HL — a noticeably brighter shade of the base diff background, used to mark changed character ranges in intra-line diffs without touching the foreground (no conflict with syntax token colours). * _syntax_text(content, filename) — new helper that calls SyntaxHighlighter.to_markup(), converts to a Rich Text (foreground colours only), and strips the trailing newline Pygments always appends so line lengths stay accurate. * _flat_add / _flat_del — now accept an optional filename hint and apply syntax highlighting via _syntax_text, then overlay the base diff background with Text.stylize(). * _intra_diff — redesigned: syntax-highlight both lines first, apply the base diff background across the whole text, then apply the brighter highlight background (bold) only over changed character ranges via a second stylize() pass. Foreground colours come entirely from syntax; background colours entirely from diff state. * _style() — passes filename (explicit_filename or from_path) through to all three helpers above, and syntax-highlights context lines (dim style overlaid on syntax colours). * Tests updated to match the new interface: _intra_diff now returns ([Text], [Text]) with spans rather than lists of single-span segments; changed-region detection checks for bright bg spans instead of bright foreground colour names. --- agent/rich_output.py | 100 +++++++++++++++++++++++++------------- tests/test_rich_output.py | 70 ++++++++++++++++---------- 2 files changed, 110 insertions(+), 60 deletions(-) diff --git a/agent/rich_output.py b/agent/rich_output.py index 38637d871a08..f18e437cfe5f 100644 --- a/agent/rich_output.py +++ b/agent/rich_output.py @@ -39,8 +39,10 @@ # Diff background colours — kept in sync with agent.display._ANSI_PLUS / _ANSI_MINUS # _ANSI_PLUS = "\033[38;2;255;255;255;48;2;20;90;20m" → rgb(20,90,20) # _ANSI_MINUS = "\033[38;2;255;255;255;48;2;120;20;20m" → rgb(120,20,20) -_DIFF_BG_ADD = "#145a14" # rgb(20, 90, 20) -_DIFF_BG_DEL = "#781414" # rgb(120, 20, 20) +_DIFF_BG_ADD = "#145a14" # rgb(20, 90, 20) — base addition background +_DIFF_BG_DEL = "#781414" # rgb(120, 20, 20) — base deletion background +_DIFF_BG_ADD_HL = "#289428" # rgb(40, 148, 40) — bright add bg for changed chars +_DIFF_BG_DEL_HL = "#b43030" # rgb(180, 48, 48) — bright del bg for changed chars # Minimum SequenceMatcher ratio to apply intra-line highlighting. # Below this the lines are too dissimilar and highlighting would be noise. @@ -424,52 +426,79 @@ def _pl(n: int) -> str: return header, separator -def _flat_del(ln: int, content: str) -> Text: - """Render a deletion line with flat (no intra-line) highlighting.""" +def _syntax_text(content: str, filename: Optional[str]) -> Text: + """Return a Rich ``Text`` with Pygments syntax colours (foreground only). + + ``syntax_highlighter`` is resolved at call time so this helper can be + defined before the module-level instance is created. + Falls back to plain unstyled text on any error. + + Pygments always appends a trailing newline token to its output.

Haskell type signatures like [Integer] rendered as [Integer\] 2. A trailing \ token (e.g. Haskell lambda \a) before a close tag like [/bold yellow] formed the Rich escape \[ — consuming the closing tag and leaking the tag text into the output. Fix: use rich.markup.escape() which doubles \ → \\ and escapes [ → \[ while leaving ] alone (] requires no escaping in Rich markup).

The padding was calculated for 8 but the visual content was 4, shifting subsequent columns right. Fix: apply apply_inline_markdown to each cell inside _render_table, measure widths via _visual_len() (ANSI-stripped len), and pad with the visual remainder.

Add _MD_OL_START_RE guard so "N. ..." lines are never treated as setext heading candidates, even when followed by a "---" separator. Without this, OL items followed by a horizontal rule (which also matches the setext H2 pattern) were promoted to dim-white headings. 2. buf_tail lines flushed at stream-end (StreamingBlockBuffer.flush()) went directly to _cprint without apply_block_line / apply_inline_md or the _tc gold-colour wrapper. Apply the same processing as the normal streaming path so links, bold, italic, and response colour are all rendered correctly for lines that were still buffered at flush time.

Extended the optional title group to cover all three CommonMark title forms. 49 new edge-case tests across ordered lists, task lists, nested blockquotes, setext-in-blockquote, and ref link resolution — covering delimiter variants, blank-line interaction, mixed list types, streaming path correctness, and depth/reset behaviour. 302 tests passing. --- agent/rich_output.py | 2 +- tests/test_rich_output.py | 379 ++++++++++++++++++++++++++++++++++++++ 2 files changed, 380 insertions(+), 1 deletion(-) diff --git a/agent/rich_output.py b/agent/rich_output.py index 73738a07b4c5..db3e4b84ec0e 100644 --- a/agent/rich_output.py +++ b/agent/rich_output.py @@ -911,7 +911,7 @@ def _bare_url(m: re.Match) -> str: #

Strict tables (pipes at both ends of every row) now render with a full box frame using box-drawing characters (┌┬┐│├┼┤└┴┘─). A row separator is drawn between every pair of content rows. 2. Loose table separators without pipes (e.g. "--- --- ---") were silently dropped because detection required "|" in the separator line. Now uses _TABLE_SEP_RE (^[\s:\-|]+$) + "-" presence check, so pipe-free separators are handled correctly.

The returned string already contains \x1b, so the outer apply_inline_markdown call (which carries reset_suffix=_DIM) hits the early-exit and never restores the outer style. Fix: add reset_suffix parameter to apply_block_line and forward it to every inner apply_inline_markdown call — including the checkbox symbols in task lists and the dim numeral in ordered lists. Update all seven call sites in cli.py to pass reset_suffix to apply_block_line.

From c03dcc2f03790298c46563b54812196208b5a1a7 Mon Sep 17 00:00:00 2001 From: KUSH42 Date: Thu, 2 Apr 2026 02:09:09 +0200 Subject: [PATCH 54/87] feat(rich_output): stateful block markdown rendering (PR4) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds rendering for the three markdown elements that require multi-line state: setext headings, multi-line blockquote continuation, and tables. Also adds line numbers to fenced code blocks. - render_stateful_blocks(): string-level pass 2 in format_response; single left-to-right scan handling setext h1/h2, blockquote lazy continuation with ▌ gutter, and pipe table buffering/rendering - StreamingBlockBuffer: state machine inserted before StreamingCodeBlockHighlighter in the streaming pipeline; same four- priority rules with _emit_next slot for mode-transition buffering - _number_code_lines(): dim right-justified line numbers prepended to every highlighted fenced code block (both batch and streaming paths) - Blockquote + code: ``` fence in streaming blockquote mode exits the blockquote so StreamingCodeBlockHighlighter can highlight it normally - ANSI lines inside a blockquote keep the ▌ gutter instead of exiting - format_response is now a three-pass pipeline (fences → stateful blocks → per-line block/inline) - cli.py: StreamingBlockBuffer threaded into streaming loop and flush --- agent/rich_output.py | 691 ++++------------------- cli.py | 107 +--- tests/test_rich_output.py | 1121 ++----------------------------------- 3 files changed, 172 insertions(+), 1747 deletions(-) diff --git a/agent/rich_output.py b/agent/rich_output.py index 7fc46c8e9d48..baa2e435a520 100644 --- a/agent/rich_output.py +++ b/agent/rich_output.py @@ -30,7 +30,6 @@ import os import re import shutil -import unicodedata from difflib import SequenceMatcher from io import StringIO from pathlib import Path @@ -50,8 +49,6 @@ _DIFF_BG_DEL = "#781414" # rgb(120, 20, 20) — base deletion background _DIFF_BG_ADD_HL = "#289428" # rgb(40, 148, 40) — bright add bg for changed chars _DIFF_BG_DEL_HL = "#b43030" # rgb(180, 48, 48) — bright del bg for changed chars -_DIFF_FG_ADD_SIGIL = "#56D364" -_DIFF_FG_DEL_SIGIL = "#FF7B72" # Minimum SequenceMatcher ratio to apply intra-line highlighting. # Below this the lines are too dissimilar and highlighting would be noise. @@ -240,32 +237,32 @@ def _ensure_styles(cls) -> None: if cls._STYLES or not _PYGMENTS: return cls._STYLES = { -

Extend SkinConfig dataclass with syntax_scheme, syntax, diff, markdown, ui_ext fields and get_syntax_styles(), get_diff(), get_markdown(), get_ui_ext() helpers. Unknown syntax_scheme falls back to "hermes" with a warning; hex colors in diff.*_bg/*_fg are validated. Add register_skin_callback() + _invalidation_callbacks list. Dispatch all callbacks in set_active_skin() so downstream caches (rich_output, display) can self-invalidate without skin_engine importing them. Assign syntax_scheme to all 7 builtin skins per spec rationale. --- hermes_cli/skin_engine.py | 455 +++++++++++++++++++++++++++++++++++++- 1 file changed, 454 insertions(+), 1 deletion(-) diff --git a/hermes_cli/skin_engine.py b/hermes_cli/skin_engine.py index 16ec39cc9b4f..80790de41efa 100644 --- a/hermes_cli/skin_engine.py +++ b/hermes_cli/skin_engine.py @@ -66,6 +66,54 @@ web_search: "🔮" # Override web_search tool emoji # Any tool not listed here uses its registry default + # Syntax highlighting color scheme + syntax_scheme: monokai # Named scheme from built-in list + # Options: hermes (default), monokai, dracula, + # one-dark, github-dark, nord, catppuccin, + # tokyo-night, gruvbox, solarized-dark + + # Token-level overrides on top of the named scheme (optional) + syntax: + keyword: "bold #FF79C6" # Any logical token name from SYNTAX_SCHEMES keys + comment: "italic dim green" + + # Diff renderer colors (hex for bg/fg; Rich style strings for line_number etc.) + # All *_bg/*_fg values MUST be 6-digit hex (#RRGGBB) + diff: + deletion_bg: "#781414" + addition_bg: "#145a14" + deletion_fg: "#ffffff" + addition_fg: "#ffffff" + intra_del_bg: "#9b1c1c" + intra_add_bg: "#166534" + intra_del_fg: "#ff8080" + intra_add_fg: "#80ff80" + line_number: "dim" # Rich style string + hunk_header: "bold cyan" # Rich style string + filename: "bold bright_white" + file_path_fg: "#B4A0FF" # inline diff only (display.py) + hunk_fg: "#787882" # inline diff only (display.py) + context_fg: "#969696" # inline diff only (display.py) + + # Markdown rendering styles (Rich style strings, except bullets/blockquote_marker) + markdown: + link: "#58A6FF underline" + code_span: "bright_white" + heading_1: "bold bright_white" + blockquote_marker: "▌" # Unicode character, not a style + bullets: ["•", "◦", "▸", "·"] # List, not a style + strike: "strike" # Rich style name for ANSI SGR 9 + + # Extended UI colors + ui_ext: + context_bar_normal: "#5f87d7" + context_bar_warn: "#ffa726" + context_bar_crit: "#ef5350" + menu_cursor: ["fg_green", "bold"] # List — prompt_toolkit style tuple + menu_highlight: ["fg_green"] + table_col_accent: "bold cyan" + panel_border: "cyan" + USAGE ===== @@ -96,15 +144,328 @@ """ import logging +import os +import re from dataclasses import dataclass, field from pathlib import Path -from typing import Any, Dict, List, Optional, Tuple +from typing import Any, Callable, Dict, List, Optional, Tuple from hermes_constants import get_hermes_home logger = logging.getLogger(__name__) +# ============================================================================= +# Syntax color schemes (logical token name → Rich style string) +# Keeping these in skin_engine.py avoids a circular import: +# rich_output imports skin_engine; skin_engine must not import rich_output. +# ============================================================================= + +# MIT-licensed originals credited inline. +SYNTAX_SCHEMES: Dict[str, Dict[str, str]] = { + "hermes": { + # Current hardcoded palette — unchanged for backward compat. + # "name" intentionally omitted: plain identifiers render as terminal default. + "keyword": "bold blue", + "keyword_type": "bold cyan", + "name_builtin": "cyan", + "name_class": "bold yellow", + "name_function": "bold yellow", + "name_function_magic": "cyan", + "name_decorator": "bright_cyan", + "name_exception": "bold red", + "comment": "dim green", + "string": "green", + "string_doc": "dim green", + "string_escape": "bold green", + "string_regex": "magenta", + "number": "magenta", + "operator": "white", + "error": "bold red", + "diff_deleted": "red", + "diff_inserted": "green", + }, + "monokai": { + # Adapted from Wimer Hazenberg's Monokai (MIT).

Add _hex_to_ansi_fg() helper and _ctx_color() accessor. - format_context_pressure() reads context_bar_normal/warn/crit hex colors from skin.get_ui_ext() with fallbacks; no _CYAN/_YELLOW hardcodes remain. skills_hub.py: - Add _skin()/_col_accent()/_col_dim()/_panel_border() module helpers. - All Table.add_column() calls use _col_accent()/_col_dim(); header_style reads table_header from skin; generic Panel border reads _panel_border(). plugins_cmd.py: - Add _skin() helper; cmd_list() reads table_col_accent/table_col_dim from skin at call time. main.py: - Add _pt_style(key, fallback) helper — reads ui_ext list/string at prompt construction time, not at module import. - Replace ("fg_green", "bold") / ("fg_green",) tuples in the three default provider/model/reasoning menus with _pt_style() calls.

Move both flush calls outside the guard so they always run when _RICH_RESPONSE is active. Also append _RST after _stream_code_hl.flush() output to ensure dangling ANSI color sequences from the syntax highlighter are always terminated. _on_tool_complete: code previews (render_read_file_preview, render_execute_code_preview, render_terminal_preview) were shown in any non-off mode. Gate them on tool_progress_mode == "verbose" since they are full raw output, not summaries. Edit diffs are unaffected and still render in new/all/verbose modes.
