| #define back | ( | x | ) | ColorArg_to_ptr(back_arg(x)) |
Create a back color suitable for use with the Colr(), colr_cat(), colr_join(), Colr_cat(), Colr_join(), Colr_center(), Colr_ljust(), and Colr_rjust() macros.
Technically, this macro accepts BasicValues, ExtendedValues, or RGB structs. However, for some of these you should be using the macros that create those things.
BasicValues can be used by their names (RED, YELLOW, etc.).
ExtendedValues can be created on the fly with ext().
RGB structs can be easily created with rgb().
Color names (char*) can be passed to generate the appropriate color value.

Uses _Generic (C11 standard) to dynamically create a ColorArg. This is used by the back() macro.
| [in] | x | BasicValue, Extended (unsigned char), RGB struct, or string (color name) for back color. |

alloca to reserve space on the stack inside of a Statement Expression. A Variable Length Array will not work inside of a statement expression. If the call causes a stack overflow, program behavior is undefined. See previous links, and here.You can also create stack-allocated escape code strings using format_bg(), format_bgx(), format_bg_RGB(), and format_bg_RGB_term().

asprintf. | #define Colr_cat | ( | ... | ) | ColorResult_to_ptr(ColorResult_new(colr_cat(__VA_ARGS__))) |
Like colr_cat(), but returns an allocated ColorResult that the Colr(), colr_cat(), colr_join(), Colr_cat(), Colr_join(), Colr_center(), Colr_ljust(), and Colr_rjust() macros will automatically free().
| [in] | ... | Arguments for colr_cat(), to concatenate. colr_free() will be called on any ColorArg, ColorResult, or ColorText pointer passed to this function. |
An allocated ColorResult with all arguments joined together.
You must free() the memory allocated by this function.
If allocation fails, NULL is returned.
If used inside of the Colr(), colr_cat(), colr_join(), Colr_cat(), Colr_join(), Colr_center(), Colr_ljust(), and Colr_rjust() macros, or their backing functions, they will free() the result. Otherwise, you are responsible for calling free().

| #define colr_cat | ( | ... | ) | _colr_join("", __VA_ARGS__, _ColrLastArg) |
Join ColorArg pointers, ColorResult pointers, ColorText pointers, and strings into one long string.
To build the ColorArg pointers, it is better to use the fore(), back(), and style() macros. The ColorArgs are heap allocated, but colr_cat() will free() them for you.
To build the ColorText pointers, it is better to use the Colr() macro, along with the fore(), back(), and style() macros. The ColorTexts are heap allocated, but colr_cat() will free() them for you.
You can use ColrResult() to wrap any allocated string and colr_cat() will free it for you. Do not wrap static/stack-allocated strings. It will result in an "invalid free". The result of Colr_join() is an allocated ColorResult, like ColrResult() returns.
If you do not want the colr macros to free your Colr-based structs/strings for you, then you will have to call colr_to_str() on the structs and build or join the resulting strings yourself.

Replace a substring in s with another string, ColorArg string, ColorResult string, or ColorText string.
If a string (char*) is used as target and repl, this is just a wrapper around colr_str_replace().
If target is a string (char*), this is a plain string-replace.
If target is a regex pattern (regex_t), it's regex match (regmatch_t) will be used to find a target string to replace in s.
If target is a regex match (regmatch_t), it's offsets will be used to find a target string in s.
If target is a NULL-terminated array of regex matches (regmatch_t**), each match will be replaced in the target string, s.
There is no difference between colr_replace() and colr_replace_all() when a NULL-terminated array of regex matches (regmatch_t**) is used.
If a ColorArg, ColorResult, or ColorText is used as repl, the appropriate colr_str_replace_<types> function is called. The function will create a string of escape-codes/text to be used as a replacement.
If repl is NULL, then an empty string ("") is used as the replacement, which causes the target string to be removed.
If you would like to replace all occurrences of the substring, use colr_replace_all().
| [in] | s | The string to operate on. Must be |
| [in] | target | A target string, regex pattern (regex_t), or regex match (regmatch_t) to replace in s. If a string is given, it must be null-terminated. |

If you would like to replace only the first occurrence of the substring, use colr_replace().
| [in] | s | The string to operate on. Must be |
| [in] | target | A target string, or regex pattern (regex_t) to replace in s. If a string is given, it must be null-terminated. |

If repl is NULL, then an empty string ("") is used as the replacement, which causes the target string to be removed.
If you would like to replace all occurrences of the substring, use colr_replace_re_all().
| [in] | s | The string to operate on. Must be |
| [in] | target | A regex pattern string (char*), regex pattern (regex_t), or regex match (regmatch_t) to replace in s. If a string is given, it must be null-terminated. |

Technically, this macro accepts BasicValues, ExtendedValues, or RGB structs. However, for some of these you should be using the macros that create those things.
BasicValues can be used by their names (RED, YELLOW, etc.).
ExtendedValues can be created on the fly with ext().
RGB structs can be easily created with rgb().
Color names (char*) can be passed to generate the appropriate color value.

If used inside of the Colr(), colr_cat(), colr_join(), Colr_cat(), Colr_join(), Colr_center(), Colr_ljust(), and Colr_rjust() macros, or their backing functions, they will free() the result. Otherwise, you are responsible for calling free().
