+# OpenInula 2.0 Parser
+
+This document describes the OpenInula 2.0 parser, which is used to parse the 2.0 API into a HIR (High-level Intermediate
+Representation) that can be used by the OpenInula 2.0 compiler.
+
+## Workflow
+```mermaid
+graph TD
+    A[OpenInula 2.0 Code] --> B[Visitor]
+    B --> C[VariableAnalyze]
+    B --> D[ViewAnalyze]
+    B --> E[fnMacroAnalyze]
+    B --> F[HookAnalyze-TODO]
+    C --> R[ReactivityParser]
+    D --> G[JSXParser]
+    G --> R
+    E --> R
+    F --> R
+    R --> |unused bit pruning|HIR
+```
+
+## Data Structure
+see `types.ts` in `packages/transpiler/babel-inula-next-core/src/analyze/types.ts`
+
+## TODO LIST
+- [ ] for analyze the local variable, we need to consider the scope of the variable
+- [ ] hook analyze
