Character recommending method and apparatus, and computer device and storage medium

A computer device, comprising at least one processor and a memory, the memory storing an instruction or a program, the instruction or the program when loaded and executed by the processor, causing the computer device to perform the steps comprising:

• converting code received by a code input interface into a syntax tree, the syntax tree comprising:
• a plurality of nodes;
• a hierarchical relationship between the plurality of nodes, the plurality of nodes and the hierarchical relationship between the plurality of nodes being used for indicating a syntactic structure of the code;
• and
• location intervals of the plurality of nodes, each location interval being used for indicating a location interval of a character set corresponding to a node in the code input interface;
• determining, according to a cursor location in the code input interface and the syntax tree, at least one reference node corresponding to the cursor location in the syntax tree by:
• traversing the plurality of nodes in the syntax tree;
• and
• determining, when the cursor location belongs to a location interval between a start location and an end location of a currently traversed node, a node corresponding to the location interval of the currently traversed node as a reference node;
• parsing the at least one reference node to obtain a parsing result by determining whether an identifier database includes an identifier having a character corresponding to the at least one reference node;
• determining at least one target character according to the parsing result, comprising:
• when the identifier database includes the identifier of the character corresponding to the at least one reference node, acquiring a target identifier comprising the character from the identifier database to use the target identifier as the at least one target character, the identifier database being used for storing at least one identifier;
• and
• when the identifier database does not include the identifier of the character corresponding to the at least one reference node, acquiring at least one target operator of a corresponding operation type of an operator node in the at least one reference node from an operator database as the at least one target character, the operator database being used for storing at least one candidate operator of at least one operation type;
• and
• recommending the at least one target character in the code input interface.

A non-transitory computer-readable storage medium, storing an instruction or a program, the instruction or the program, when loaded and executed by a processor of a computer device, causing the computer device to perform the steps, comprising:

• a plurality of nodes;
• a hierarchical relationship between the plurality of nodes, the plurality of nodes and the hierarchical relationship between the plurality of nodes being used for indicating a syntactic structure of the code;

• location intervals of the plurality of nodes, each location interval being used for indicating a location interval of a character set corresponding to a node in the code input interface;

• and
• recommending the at least one target character in the code input interface.
