Example Entry

An entry in the miniCTX dataset consists of the theorem statement, preceding file contents, and metadata information. For example, given the following theorem s_eq_pow_two in context:

import Mathlib.Data.Real.Basic

/-!
# Square function
We define the squaring function `s : ℝ → ℝ` to be `s x := x * x`.
-/

def s (x : ℝ) : ℝ := x * x

lemma s_eq_pow_two {x : ℝ} : s x = x ^ 2 := by
  rw [s, pow_two]

The problem is formatted in JSON as follows:

{
  # Preceding file content
  "srcContext": "import Mathlib.Data.Real.Basic\n\n/-!\n# Square function\nWe define the squaring function `s : ℝ → ℝ` to be `s x := x * x`.\n-/\n\ndef s (x : ℝ) : ℝ := x * x\n\n",

  "theoremStatement": "lemma s_eq_pow_two {x : ℝ} : s x = x ^ 2",

  # Fully qualified theorem name
  "theoremName": "s_eq_pow_two",

    "tokenPositionInFile": 152,

Description of Each Entry

• srcContext: The context of the source file preceding the theorem, including imports and relevant definitions. This provides necessary background to understand the theorem.
• theoremStatement: The statement of the theorem being proved.
• theoremName: The name of the theorem.
• fileCreated: The git commit hash indicating when the file was created.
• theoremCreated: The git commit hash indicating when the theorem was added.
• file: The name of the file containing the theorem.
• positionMetadata:
  • lineInFile: The line number in the file where the theorem is located.
  • tokenPositionInFile: The number of tokens in the file before the theorem starts.
  • theoremPositionInFile: The number of premises (definitions, theorems) before the theorem in the file.
• dependencyMetadata:
  • inFilePremises: Indicates whether the theorem uses definitions or lemmas defined in the same file.
  • numInFilePremises: The number of definitions or lemmas from the same file that the theorem relies on.
  • repositoryPremises: Indicates whether the theorem uses definitions or lemmas defined in another file within the same repository.
  • numRepositoryPremises: The total number of definitions or lemmas from the repository (including the current file) that the theorem depends on.
  • numPremises: The total number of premises the theorem depends on, regardless of whether they are from the same file, the repository, or external sources.
  • importedModules: Lists the modules imported in the current file.
• proofMetadata:
  • hasProof: Indicates whether the theorem has a proof.
  • proof: The proof of the theorem.
  • proofType: The type of proof, term proof or tactic proof.
  • proofLengthLines: The length of the proof in lines.
  • proofLengthTokens: The length of the proof in tokens.
