Software tool
A software tool is a program or application that software developers use to help create or maintain other programs and applications. The term usually refers to relatively simple programs that can be used together to accomplish a task, much as one might use multiple hand tools to fix a physical object.
The history of software tools began with the first computers in the early 1950s that used linkers, loaders, and control programs. Tools became famous with Unix in the early 1970s with tools like grep, awk and make that where meant to be combined flexibly with pipes.
Tools were originally simple and light weight. As some tools have been maintained, they have been integrated into more powerful integrated development environments (IDEs). These environments can make searching and editing much easier, however they lack the ability to massage code, like old Unix tools.
The distinction between tools and applications can become murky. For example, developers use simple databases (such as a file containing list of important values) all the time as tools. However a full blown database is usually thought of as much more than a tool.
The ability to use a variety of tools productively is one hallmark of a skilled software engineer.
List of tools
Software tools come in many forms:
- Source Code Control: SCCS, RCS, CVS, SourceSafe, PVCS, ClearCase
- Compilation and linking tools: Make, automake
- Search: grep, find
- Editors: emacs, vi
- Scripts: Shell, Perl
- Parsing: Lex, Yacc
- Bug Databases: gnats, Bugzilla
List of IDEs
Integrated development environments (IDEs) combine the features of many tools, into one complete package. They are usually simpler and easier to do simple tasks, such as seaching for content only in files in the project. They usually have a much harder time with linking tools together, such as preprocessors and code generators.
