Skill Claude Code

A lexer operation that decodes supported escape sequences, such as `\n`, `\t`, and escaped quotes. Escape sequences let source text represent special characters.

Skill Claude Code

A syntax operation for dictionary literals such as `{key: value}`. It reads the key-value pairs between the braces.

FuRongJun-1999/dsh-memory

Skill Claude Code

A compile-time check that confirms every condition space used by code has already been declared. Here, a condition space is treated as part of the type system.

FuRongJun-1999/dsh-memory

Skill Claude Code

A compiler analysis for finding names used inside a nested function that come from an outer scope. These names are called free variables and may need to be stored for the nested function.

FuRongJun-1999/dsh-memory

Skill Claude Code

A lexer operation that reads identifiers: continuous sequences of letters, numbers, underscores, or supported CJK characters. A lexer is the part of a compiler that turns source text into tokens.

FuRongJun-1999/dsh-memory

Skill Claude Code

A lexer component that reads quoted string values, handles escape characters, and marks strings that do not have a closing quote. A lexer is the part of a language tool that breaks source text into tokens.

Skill Claude Code

A debugger feature that pauses a program only when a specified condition is true. A debugger is a tool for stopping and examining a running program.

FuRongJun-1999/dsh-memory

Skill Claude Code

A compiler optimization that copies a loop body a fixed number of times instead of repeating the loop control for every iteration. Loop unrolling can make some code faster, but excessive copying can make programs larger.

FuRongJun-1999/dsh-memory

Skill Claude Code

A compiler optimization that replaces a call through a class interface with a direct call when there is only one possible implementation. This removes a level of method-selection work.

FuRongJun-1999/dsh-memory

Skill Claude Code

A compiler optimization that moves a calculation outside a loop when its result does not change between iterations. The calculation then runs once instead of repeatedly.

FuRongJun-1999/dsh-memory

Skill Claude Code

A syntax handler for conditional expressions written as condition, question mark, true value, colon, and false value. It chooses one of two values based on the condition.

FuRongJun-1999/dsh-memory

Skill Claude Code

A character classifier that labels each character as a letter, number, whitespace, or other character. This is a basic step in turning source text into meaningful language elements.

FuRongJun-1999/dsh-memory

Skill Claude Code

A bytecode inspection tool that lists low-level instructions with their addresses, operations, and arguments. Bytecode is the intermediate code produced by a compiler before a program runs.

FuRongJun-1999/dsh-memory

Skill Claude Code

A debugging tool that shows the error location and the chain of function calls that led there. This chain is often called a stack trace or traceback.

FuRongJun-1999/dsh-memory

Skill Claude Code

A syntax handler that splits multiple statements separated by semicolons into an ordered sequence. A statement is one complete instruction in a programming language.

FuRongJun-1999/dsh-memory

Skill Claude Code

A compiler optimization that removes instructions which cannot be reached, such as instructions after an unconditional jump. A compiler turns source code into executable instructions.

FuRongJun-1999/dsh-memory

Skill Claude Code

A compiler optimization that moves instructions earlier when they do not depend on instructions around them. Instruction scheduling arranges compiled operations while preserving their required dependencies.

FuRongJun-1999/dsh-memory

Skill Claude Code

A data-flow analysis that tracks where values are defined and where they are used. A def-use chain links an assignment of a value to the later code that reads it.

FuRongJun-1999/dsh-memory

Skill Claude Code

A lexical check for suffixes on numeric literals, such as hexadecimal or binary notation and k or m suffixes. Lexical analysis is the step that splits source text into meaningful tokens.

FuRongJun-1999/dsh-memory

Skill Claude Code

A loop-cost estimate based on the number of instructions in the loop body multiplied by the number of iterations. A loop repeats the same block of program code.

FuRongJun-1999/dsh-memory

Skill Claude Code

A bytecode instruction-size check that measures how many encoded bytes each instruction uses. Bytecode is the compact form of program instructions used by a runtime or virtual machine.

FuRongJun-1999/dsh-memory

Skill Claude Code

A compiler optimization that replaces a variable known to have a constant value with that value directly. A compiler translates source code into instructions for a computer.

FuRongJun-1999/dsh-memory

Skill Claude Code

A debugger variable watch that looks up a watched name in the program's symbol table and returns its current value. A debugger is a tool for inspecting a program while it runs.

FuRongJun-1999/dsh-memory

Skill Claude Code

A file-header check for C3 .pbc files. It checks the file's identifying marker, called a magic number, and whether its format version is compatible.
