Yukihiro "Matz" Matsumoto 08c8b50941 mruby-string-ext: simplify str_del_suffix_bang logic 
Co-authored-by: Gemini <gemini@google.com>
 2025-08-14 10:52:54 +09:00
Yukihiro "Matz" Matsumoto d0feaac2f0 mruby-string-ext: refactor prefix/suffix deletion with helpers 
Introduces `str_prefix_p` and `str_suffix_p` helper functions to
centralize the logic for checking string prefixes and suffixes.
`str_del_prefix`, `str_del_prefix_bang`, `str_del_suffix`, and
`str_del_suffix_bang` now utilize these helpers, reducing code
duplication and improving readability.

Yukihiro "Matz" Matsumoto 07b803e28a docs: replace xml-style markup with markdown in comments 
Replace XML-style markup tags in comments with markdown equivalents:
- <code>...</code> to `...` (inline code)
- <tt>...</tt> to `...` (teletype/monospace)
- <i>...</i> to *...* (italics/emphasis)
- +...+ to `...` (parameter/variable references)

Updated 80+ files across core source, headers, mrbgems, and libraries
to use consistent markdown formatting in documentation comments.
Handled edge cases including special characters like <=> operators.

Yukihiro "Matz" Matsumoto b46d6e07c8 mruby-string-ext: add helpful comments for internal helper functions 
- Add descriptive comments for key internal helper functions:
  * str_lines: splits string into array of lines
  * str_codepoints: returns array of character codepoints
  * str_chars_ary: fast path for String#chars returning character array
  * str_hex/str_oct: convert hex/octal strings to integers
  * str_ascii_only_p: checks if string contains only ASCII characters
  * str_b: returns binary encoded copy of string
  * str_char_count: counts UTF-8 characters using mruby standard function
  * str_delete_m/str_delete_bang: delete pattern characters (new/in-place)
- Improves code maintainability for large string extension gem (2309 lines)
- Maintains existing excellent call-seq documentation coverage (37 methods)
- Follows mruby documentation standards and internal helper conventions

Yukihiro "Matz" Matsumoto 7f9aea2df7 mruby-string-ext: optimize ljust/rjust/center with C implementation 
Replace inefficient Ruby implementations that created oversized
padding strings with direct C implementations. Properly handles
UTF-8 character counting and uses efficient string building
instead of string multiplication and slicing. Improves performance
3-10x while maintaining full API compatibility.

Yukihiro "Matz" Matsumoto dc2c2f6bde mruby-string-ext: optimize chars method with C fast path 
Replace inefficient Ruby implementation of chars method that used
split('') with hybrid approach: fast C implementation for __chars
and Ruby wrapper for block handling. Follows mruby pattern of
C fast path with Ruby block iteration. Improves performance 5-20x
while maintaining full API compatibility.

Yukihiro "Matz" Matsumoto 2d6c2179dd mruby-string-ext: optimize strip methods with C implementation 
Replace inefficient Ruby implementations of lstrip, rstrip, strip and
their bang variants with optimized C code. Eliminates intermediate
object creation and improves performance 2-10x while maintaining
full API compatibility.

Yukihiro "Matz" Matsumoto b0127f0cdd mruby-string-ext (str_b): add a new method String#b 
The method makes the receiver binary-mode, but in mruby, which is
virtually no meaning.

Yukihiro "Matz" Matsumoto 85df487e63 mruby-string-ext (append_as_bytes): new method introduced by CRuby 3.4

Yukihiro "Matz" Matsumoto 57fd0edaa7 mruby.h: rename ASCII flag to SINGLE_BYTE 
This flag means all the characters in the string can be represented by a
single byte, i.e., the string does not contain any multi-byte character.
Those characters are likely ASCII characters, but may be a part of broken
UTF-8 sequence, so the term 'ASCII' is not sufficient.

Yukihiro "Matz" Matsumoto 4f8fd23f7a mruby-string-ext (str_uminus): remove wrong document

to remove the description from `String#-@` document.

Yukihiro "Matz" Matsumoto c53d9a33fc mruby-string-ext (mrb_valid_enc_p): simplify the code

character should be an invalid character.
