In exponent(), 'base *= base;' should not run
when base is 65536, since it overflows an int32_t.
This also optimizes exponent() based on
gcc and clang -O3 test cases in godbolt.org.
Fixes#683 and #691
The lexer's raw mode for reading macro args already attempted
to handle semicolons inside string literals, versus outside ones
which start comments. This change reuses the same function for
reading string literals in normal and raw modes, also handling:
- Commas in strings versus between macro args
- Character escapes
- {Interpolations} and \1-\9 args inside vs. outside strings
- Multi-line string literals
Macro args now allow escaping '\', '"', and '\\'.
A consistent model for expanding macro args and interpolations,
within macro args, string literals, and normal context:
- "{S}" should always equal the contents of S
- "\1" should always act like quoting the value of \1
In preparation for an upcoming change
Makes for nicer error messages, complaining about EOF instead of newlines
The hack had to be kept for the lexer raw mode to avoid a bug;
see the relevant code comment for more info.
- Make it work inside pipelines
- Add RGBFIX tests to the suite
- Be more flexible in accepted MBC names
- Add warnings for dangerous or nonsensical input params
- Improve man page
This is not used in all bison versions, which causes a
"defined but not used" warning for the 'rgbasm_yytnamerr'
replacement, treated as an error by 'make develop'.
Removal of colon-less labels lifted the grammar ambiguity that
prevented `RL` from being usable as a variable declarator.
Thus, reinstate its functionality.
Fixes#669Closes#368Closes#624
Deprecate PRINTT, PRINTV, PRINTI, and PRINTF
Default STRFMT("%f") to 5 fractional digits like "{f:}"
Any use of string formatting will share this default
Document the existing `ROUND`, `CEIL`, and `FLOOR` functions
Also update the trig function docs for searchability
Implement `POW` and `LOG`
Addresses part of #675
Implement ** for integer exponents
** has higher precedence than -, like Python, so -3**4 == -(3**4) == 81
