# Modders' guide to BAMM! graphics references
# Place your conversions in a file named bamm_gfx_<identifier here>.txt . The file should be encoded in codepage 437, the same as the Dwarf Fortress raws.
# Start by defining names for your target graphics elements.
# These names must always start with @.
# So if you want to reference the background color being used for the Lion creature token, you can do that with this definition:
# CREATURE:LION|COLOR::@lionbgcolor
# or
# CREATURE:LION|COLOR::@lionbgcolor:
# If you want to reference the *whole* color of the lion tile, which is a 3-argument value, you can add a number after the @, like this:
# CREATURE:LION|COLOR:@3lionfullcolor
# Or you can declare references for each argument of the lion color individually:
# CREATURE:LION|COLOR:@lionfgcolor:@lionbgcolor:@lionbrightness
# The name is case-sensitive and can contain any character in the alphabet. Numbers are not allowed except immediately after the @. Special characters, including underscores, are not allowed.
# You can also create generic all-graphics-belonging-to-this-object referents this way:
# CREATURE:LION|@allLionTags
# BE AWARE: trying to define non-graphics or partially non-graphic referents won't work. Referent declarations which include non-graphic information will simply be ignored.
# OK, now that we have our referents, it's time to use them to modify raws.
# creature_modded.txt
# [CREATURE:MODDED_LION]
# @allLionTags
# This sets all of the modded lion's graphics equal to the lion's graphics, in any graphics set.
# However, this "copy all" functionality couldn't be used to set properties belonging to a non-creature object:
# [INORGANIC:LIONSTONE] This won't work
# @allLionTags This won't work
# In order to make lionstone the color of a lion, you'll need to reference the colors instead:
# [INORGANIC:LIONSTONE]
# [DISPLAY_COLOR:@3lionfullcolor]
# NB. References are always made to graphics as declared in the graphics source raws. If you declare a lion to use a deer's graphics, and a deer to use a lion's graphics, they'll swap, not have the same graphics.
# Eventually I intend to expand this to include the ability to apply these changes based on the properties of entries, but right now, this should be enough.

# Otherwise, match it against a template
# Then match it against the GRAPHICS NODES that meet that template
# Not the bound node or the target node.
# (TODO make each template node hold lists of objects that refer to it, by function.)
# If a partial definition matches more than one object, keep track of all of them so they can be narrowed down later
# If a full definition matches more than one object, write a warning to the logfile and choose one arbitrarily to go with.
# If a full definition matches no graphics object, write a warning to the log and try it on target objects.
# If a full definition matches neither graphics nor target, write an error to the log.
# Put the mapping of referent name to an object storing the reference info into graphics_refs
else:
# Get a collection of all the targets that meet the reference

"""A TreeNode tailored for holding graphics templates.
TemplateNodes store the patterns which define what tags are graphics tags, and which of their tokens are immutable, identifying, graphical, or irrelevant. Each TemplateNode represents the template for a single type of graphics tag.
Members:
* _tag is the template string. It is a series of tokens separated by colons. Each token is one of the following:
* LITERAL. This is a string, usually in all caps, which must be present in this exact form for a tag to match this template. The first token in a template is always a literal. Enums (e.g. the PLANT_GROWTH timing values of ALL and NONE) may simulated by splitting a template into multiple templates, one for each enum, with the enum in question present as a literal.
* VARIABLE. This is a single character, '?' '$' or '&' (quotes not present in _tag).
* '?' indicates that this is a graphics token. When matching a tag to a template, this can match any value. When merging occurs, this token's value will come from the graphics source.
* '&' indicates that this is an info token. When matching a tag to a template, this can match any value. When merging occurs, this token's value will come from the raw source.
* '$' indicates that this is an identifier token. When matching a tag to a template, this can match any value; but for two tags to match each other, they must share the same values for all identifier tokens in their template.
* VARIABLE RANGE. This is a variable character, followed by a range in parentheses, e.g. ?(0,3). This means that the tag can contain 0-3 (inclusive) tokens in this position, all of which hold graphical information. The second value is optional - if omitted, it means there is no upper bound on how many tokens can be in this series.
For examples, please see graphics_templates.config . The string between each pipe ( | ) is a valid TemplateNode._tag .
* _children is a dict containing the TemplateNodes representing the types of tags which are allowed to be children of the type of tag represented by this TemplateNode. The keys are the full _tags of the child TemplateNodes.
* _childref is the same as _children, but indexed by the first token (the "value") of the child's _tag, instead of the full _tag. For convenience/performance only.
* _parent is the TemplateNode representing the type of tag that the type of tag this TemplateNode represents can be a child of.
* _is_graphics_tag is a boolean that lets us know if this tag is a graphics tag, as opposed to a template included because it can have graphics children. This is necessary because some graphics tags are composed of only a single literal token.
