(IDE). In many cases, particularly for simpler use, simple ad hoc techniques are used instead of a tool, such as print debugging instead of using a debugger, manual timing (of overall program or section of code) instead of a profiler, or tracking bugs in a text file or spreadsheet instead of a bug tracking system. The distinction between tools and applications is murky. For example, developers use simple databases (such as a file containing a list of important values) all the time as tools. However a full-blown database is usually thought of as an application or software in its own right. For many years, computer-assisted software engineering (CASE) tools were sought after. Successful tools have proven elusive. In one sense, CASE tools emphasized design and architecture support, such as for UML. But the most successful of these tools are IDEs.

Uses of programming tools

Translating from human to computer language

Modern computers are very complex and in order to productively program them, various abstractions are needed. For example, rather than writing down a program's binary representation a programmer will write a program in a

s and linkers translate a program from a human write-able and readable source language into the bits and bytes that can be executed by a computer. Interpreters interpret the program on the fly to produce the desired behavior. These programs perform many well defined and repetitive tasks that would nonetheless be time-consuming and error-prone when performed by a human, like laying out parts of a program in memory and fixing up the references between parts of a program as a linker does. Optimizing compilers on the other hand can perform complex transformations on the source code in order to improve the execution speed or other characteristics of a program. This allows a programmer to focus more on higher level, conceptual aspects of a program without worrying about the details of the machine it is running on.

Making program information available for humans

Because of the high complexity of software, it is not possible to understand most programs at a single glance even for the most experienced software developer. The abstractions provided by high-level programming languages also make it harder to understand the connection between the source code written by a programmer and the actual program's behaviour. In order to find bugs in programs and to prevent creating new bugs when extending a program, a software developer uses some programming tools to visualize all kinds of information about programs. For example, a

debugger A debugger or debugging tool is a computer program used to software testing, test and debugging, debug other programs (the "target" program). The main use of a debugger is to run the target program under controlled conditions that permit the pr ...

allows a programmer to extract information about a running program in terms of the source language used to program it. The debugger can compute the value of a variable in the source program from the state of the concrete machine by using information stored by the compiler. Memory debuggers can directly point out questionable or outright wrong memory accesses of running programs which may otherwise remain undetected and are a common source of program failures.
