1. Introduction to the GNAT Component CollectionΒΆ
The reusable library known as the GNAT Component Collection (GNATColl) is based on one main principle: general-purpose packages that are part of the GNAT technology should also be available to GNAT user application code. The compiler front end, the GNAT Programming Studio (GPS) Interactive Development Environment, and the GNAT Tracker web-based interface all served as sources for the components.
The GNATColl components complement the predefined Ada and GNAT libraries and deal with a range of common programming issues including string and text processing, memory management, and file handling. Several of the components are especially useful in enterprise applications.
The next chapter explains how to build and install GNATColl. The remainder of this document then describes the various components that make up the collection:
Scripts: Embedding script languages
Traces: Logging information
Memory: Monitoring memory usage
Mmap: Reading and writing files
Boyer-Moore: Searching strings
Paragraph filling: Formatting text
Templates: Generating text
Email: Processing email messages
Ravenscar: Patterns for multitasking
Storage Pools: Controlling memory management
VFS: Manipulating files
Tribooleans: Three-state logic
Geometry: Primitive geometric operations
Projects: Manipulating
gpr
filesRefcount: Reference counting
Config: Parsing configuration files
Pools: Controlling access to resources
JSON: Handling JavaScript Object Notation
SQL: Database interface
