A compiler is a computer program (or set of programs) that translates text written in a computer language (the source language) into another computer language (the target language). The original sequence is usually called the source code and the output called object code. Commonly the output has a form suitable for processing by other programs (e.g., a linker), but it may be a human readable text file.

The most common reason for wanting to translate source code is to create an executable program. The name "compiler" is primarily used for programs that translate source code from a high level language to a lower level language (e.g., assembly language or machine language). A program that translates from a low level language to a higher level one is a decompiler. A program that translates between high-level languages is usually called a language translator, source to source translator, or language converter. A language rewriter is usually a program that translates the form of expressions without a change of language.

A compiler is likely to perform many or all of the following operations: lexing, preprocessing, parsing, semantic analysis, code optimizations, and code generation.

eWEEK Labs Walk-Through: Lotus Symphony 1.1
Mon, 06 Oct 2008 21:35:35 -0400
Lotus Symphony 1.1 is a freely-available office productivity suite from IBM that brings together a trio of word processor, spreadsheet and presentation applications under a Big Blue label. Symphony's interface is new, based on Eclipse, but its internals are old, based on OpenOffice.org 1.1.4; the result is a fairly good productivity suite with an interface that's much fresher-and a feature set that's more stale-than those that grace the OpenOffice.org 3.0 release I recently tested. - Upon firing up the Lotus Symphony 1.1 word processor application, I was impressed right away by its tabbed interface, which makes switching between different documents as well as spreadsheets and presentations as easy as shifting between tabbed pages in Firefox.
