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. thomas@astro.psu.edu

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.c.

Function Documentation

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

Here is the caller graph for this function:

static void check_formulae ( void ) [static]

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.

Makes sure we actually have the requested artifact and archetype.

Parameters:

rp	recipe we want to check.

Returns:: 1 if recipe is ok, 0 if missing something (and LOG() to error).

Here is the caller graph for this function:

static long find_ingred_cost ( const char * name ) [static]

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.

Parameters:

name	ingredient we're searching for. Can start with a number.

Returns:: cost of ingredient, -1 if wasn't found.

Here is the call graph for this function:

Here is the caller graph for this function:

archetype* find_treasure_by_name	(	const treasure *	t,
		const char *	name,
		int	depth
	)

Find a treasure with a matching name.

The 'depth' parameter is only there to prevent infinite loops in treasure lists (a list referencing another list pointing back to the first one).

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.
