"ProgrammingLanguage" (Built-in Classifier)

Recognize the programming language of a code snippet.

Classes

Details

  • This classifier assumes the string input is written in a unique programming language. The probabilities reflect the belief in which language the program is written, not the proportion of languages.

Basic Examples  (2)

Determine the language of a given code:

Wolfram Language code: Classify["ProgrammingLanguage", "int main() { const char *p = \"Hello\"; while(*p++) printf(\"%c\",*p); return 0; }"]

Obtain the probabilities for the most likely classes:

Wolfram Language code: Classify["ProgrammingLanguage", "/^.?$|^(..+?)\\1+$/", "TopProbabilities"]

Obtain a ClassifierFunction for this classifier:

Wolfram Language code: c = Classify["ProgrammingLanguage"]

Apply the classifier to a code snippet:

Wolfram Language code: c["def insert(self,k): self.heapList.append(k) self.currentSize = self.currentSize + 1 self.percUp(self.currentSize)"]

Scope  (1)

Load the ClassifierFunction corresponding to the built-in classifier:

Wolfram Language code: c = Classify["ProgrammingLanguage"]

Obtain the possible classes:

Wolfram Language code: Information[c, "Classes"]

Options  (2)

ClassPriors  (1)

Use a custom ClassPriors to restrict the possible outputs:

Wolfram Language code: Classify["ProgrammingLanguage", "TrieNode *newNode() { TrieNode *temp = new TrieNode; temp->value = 0; temp->arr[0] = temp->arr[1] = NULL; return temp; }", ClassPriors -> <| Entity["ProgrammingLanguage", "C::p5vhv"] -> 0.25, Entity["ProgrammingLanguage", "C::5zm8v"] -> 0.25, Entity["ProgrammingLanguage", "C::y7pg6"] -> 0.5|>]

IndeterminateThreshold  (1)

Use a custom IndeterminateThreshold:

Wolfram Language code: Classify["ProgrammingLanguage", "TrieNode *newNode()", IndeterminateThreshold -> 0.6]

Neat Examples  (1)

Obtain different possible languages with their corresponding probabilities:

Wolfram Language code: possiblelanguages = Classify["ProgrammingLanguage", "/^.?$|^(..+?)\\1+$/", "Probabilities"];
