Detailed Description

Basic stuff for use with the alchemy code. Clearly some of this stuff could go into server/alchemy, but I left it here just in case it proves more generally useful.

Nov 1995 - file created by b.t. thoma.nosp@m.s@as.nosp@m.tro.p.nosp@m.su.e.nosp@m.du

Our definition of 'formula' is any product of an alchemical process. Ingredients are just comma delimited list of archetype (or object) names.

Example 'formula' entry in libdir/formulae: Object transparency chance 10 ingred dust of beholdereye,gem arch potion_generic

An ingredient is a name, which can contain an initial number for how many are needed.

Definition in file recipe.cpp.

Function Documentation

◆ build_stringlist()

static void build_stringlist	(	const char *	str,
		char ***	result_list,
		size_t *	result_size
	)

static

Split a comma separated string list into words.

Parameters

	str	the string to split
[out]	result_list	pointer to return value for the newly created list; the caller is responsible for freeing both result_list and *result_list.
[out]	result_size	pointer to return value for the size of the newly created list

◆ check_formulae()

bool check_formulae ( void )

Check if formula don't have the same index.

Since we are doing a squential search on the formulae lists now, we have to be carefull that we dont have 2 formula with the exact same index value. Under the new nbatches code, it is possible to have multiples of ingredients in a cauldron which could result in an index formula mismatch. We *don't *check for that possibility here. -b.t.

LOG() to error level.

Todo:: check archetypes exist, check coherence (skill present, cauldron ok, and such things), set chance to 0 for combinations

◆ find_recipe_for_tool()

recipe* find_recipe_for_tool	(	const char *	tool,

This function can be called multiple times to browse the whole list, using the 'from' parameter.

Parameters

tool	tool's archetype name.
from	formula to search from, if NULL from the first one.

Returns: matching formula, NULL if none matching.

Parameters

t	item of treasure list to search from
name	name we're trying to find. Doesn't need to be a shared string.
depth	current depth. Code will exit if greater than 10.

Returns: archetype with name, or NULL if nothing found.

Try to find an ingredient with specified name.

If several archetypes have the same name, the value of the first one with that name will be returned. This happens for the mushrooms (mushroom_1, mushroom_2 and mushroom_3). For the monsters' body parts, there may be several monsters with the same name. This is not a problem if these monsters have the same level (e.g. sage & c_sage) or if only one of the monsters generates the body parts that we are looking for (e.g. big_dragon and big_dragon_worthless).

Will also search in artifacts.
