\grammartermnc{} grammar terminal macro not converted

[lefticus]

Problem

The \grammartermnc{} macro (marking grammar terminals without code formatting) is not being converted. The raw LaTeX macro appears in a code example.

Affected Files

• temp.md (1 instance)

Example

Line 961:
Actual:

T x = \grammartermnc{template-argument} ;

Expected:

T x = *template-argument* ;

(or similar italic/emphasized formatting for the grammar nonterminal)

Context

Grammar terminals and nonterminals in the C++ standard are typically rendered in:

• Italic font for nonterminals
• Monospace/code font for terminals
• The nc suffix likely means "no code formatting"

Impact

Major - While only 1 instance, this appears in template syntax specification which is critical reference material. The unconverted macro makes the example harder to understand.

Fix Required

Add support for \grammartermnc{} macro in cpp-grammar.lua or cpp-macros.lua filter. Should convert to emphasized text (italic: *terminal*).

• General grammar notation handling in cpp-grammar.lua

[lefticus]

Fixed in commit da34004.

Added \grammartermnc{} conversion to clean_code_common() function. The macro is now unwrapped (content preserved, wrapper removed) since markdown doesn't support formatting inside code blocks.

Output: T x = \grammartermnc{template-argument} ; → T x = template-argument ;

Test results: 31/31 tests pass in test_code_blocks.py

Files changed:

• src/cpp_std_converter/filters/cpp-common.lua (lines 1897-1902)
• tests/test_filters/test_code_blocks.py (added test_grammartermnc_in_code_block)
• n4950/temp.md (automatically fixed - line 960)
