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.c.

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

Split a comma separated string list into words.

Parameters
strthe string to split
[out]result_listpointer to return value for the newly created list; the caller is responsible for freeing both *result_list and **result_list.
[out]result_sizepointer to return value for the size of the newly created list

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.

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

Parameters

Returns

void dump_alchemy ( void  )
void dump_alchemy_costs ( void  )
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
nameingredient we're searching for. Can start with a number.
Returns
cost of ingredient, -1 if wasn't found.

recipe* find_recipe_for_tool ( const char *  tool,
recipe from

Find a recipe for a specified tool.

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

Parameters
tooltool's archetype name.
fromformula to search from, if NULL from the first one.
Returns
matching formula, NULL if none matching.

archetype* find_treasure_by_name ( const treasure t,
const char *  name,

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
titem of treasure list to search from
namename we're trying to find. Doesn't need to be a shared string.
depthcurrent depth. Code will exit if greater than 10.
Returns
archetype with name, or NULL if nothing found.
