Since presym is now mandatory, mruby.h includes presym.h so that MRB_SYM() macros are available everywhere without explicit include. Remove redundant #include <mruby/presym.h> from all source files. Co-authored-by: Claude <noreply@anthropic.com>
mruby-symbol-ext
This gem extends mruby's Symbol class with additional useful methods.
Methods
Here are the methods added to the Symbol class:
capitalize
- call-seq:
sym.capitalize -> symbol - Returns a new symbol with the first character converted to uppercase and the remainder to lowercase. Equivalent to
sym.to_s.capitalize.intern.
downcase
- call-seq:
sym.downcase -> symbol - Returns a new symbol with all characters converted to lowercase. Equivalent to
sym.to_s.downcase.intern.
upcase
- call-seq:
sym.upcase -> symbol - Returns a new symbol with all characters converted to uppercase. Equivalent to
sym.to_s.upcase.intern.
casecmp(other_symbol)
- call-seq:
sym.casecmp(other) -> -1, 0, +1 or nil - Performs a case-insensitive comparison between two symbols. Returns -1, 0, or +1 if
other_symbolis a symbol. Returnsnilifother_symbolis not a symbol.
casecmp?(other_symbol)
- call-seq:
sym.casecmp?(other) -> true, false, or nil - Returns
trueif the receiver andother_symbolare equal after case folding,falseif they are not equal. Returnsnilifother_symbolis not a symbol.
empty?
- call-seq:
sym.empty? -> true or false - Returns
trueif the symbol's string representation is empty (i.e.,:""),falseotherwise.
length / size
- call-seq:
sym.length -> integersym.size -> integer
- Returns the length of the symbol's string representation.
sizeis an alias forlength.
Symbol.all_symbols (Conditional)
- call-seq:
Symbol.all_symbols => array - Returns an array of all symbols currently in mruby's symbol table.
- Note: This method is only available if mruby is compiled with the
MRB_USE_ALL_SYMBOLSdefine.
