次のような動的なフォルダー構造の構文が設定されています。
:projectRoot:/dev/model/:parentHierarchy:/:assetName:/data/obj
:projectRoot:/dev/model/:parentHierarchy:/:assetName:/data/fbx
:projectRoot:/asset/shots/:parentHierarchy:/animation/:assetName:/scenes
:projectRoot:/asset/shots/:parentHierarchy:/rendering/:assetName:/scenes
2 つのコロン ':' の間の単語は変数です。ここで、1 つのパスに基づいて、projectRoot、parentHierarchy、および assetName を取得します。
projectRoot 変数と parentHierarchy 変数を使用すると、1 つ以上のフォルダーを存在させることができるため、サブフォルダーを保持できます。assetName 変数は、1 つのフォルダーに制限されています。これらは、以下に示す私の試みのように定義されています。
だから私が渡すとしましょう：
C:/Projects/foo/dev/model/props/furniture/couch/data/
これは次のように返されます。
projectRoot = C:/Projects/foo/
parentHierarchy = props/furniture
assetName = couch
次に、ルール セットで定義されたすべてのパスが存在するかどうかを確認することもできます (ただし、これは比較的簡単です)。
C:/Projects/foo/dev/model/props/furniture/couch/data/obj
C:/Projects/foo/dev/model/props/furniture/couch/data/fbx
C:/Projects/foo/asset/shots/props/furniture/animation/couch/scenes
C:/Projects/foo/asset/shots/props/furniture/rendering/couch/scenes
これが私の現在のテスト実装です：
import os
import re
variableRegex = re.compile(":[\w]*:")
def getRules():
return [":projectRoot:/dev/model/:parentHierarchy:/:assetName:/data/obj",
":projectRoot:/dev/model/:parentHierarchy:/:assetName:/data/fbx",
":projectRoot:/asset/shots/:parentHierarchy:/animation/:assetName:/scenes",
":projectRoot:/dev/model/:parentHierarchy:/:assetName:/data/obj"]
def getVarRules():
"""
These rules define how many hierarchy depth each variable represents.
(This is simplified from the actual code I'm working with to ease the example for the question)
-1 defines that the variable can hold one or more folders (nested folders), thus never zero
1 defines it will can't have subfolders and will define a single folder

return {":projectRoot:": -1,
":parentHierarchy:": -1,

現在、静的部分で構成されるパスのみが検索されます (変数ルールはチェックされません。ここに追加する方法がわかりません)。
また、ルールに従うフルパスから変数を解析しません。
