- FINAL CUT
- The FINAL CUT is a C++ class library and widget toolkit with full mouse support for creating a text-based user interface. The library supports the programmer to develop an application for the text console. It allows the simultaneous handling of multiple text windows on the screen. The structure of the Qt framework was originally the inspiration for the C++ class design of FINAL CUT. It provides common controls like dialog boxes, push buttons, check boxes, radio buttons, input lines, list boxes, status bars and so on.
- FLIF
- FLIF is a novel lossless image format which outperforms existing image formats in terms of compression ratio. It works well on any kind of image (photographic, line art, computer graphics, etc.) and also supports animations. FLIF images (or animations) can be progressively decoded, which makes the format potentially very suitable for responsive web design. This is the reference implementation of FLIF, which includes a command-line tool (flif) to convert between FLIF and PNG/PNM/PAM, a decoding library (libflif_dec), an encoding library (libflif_enc), some scripts (gif2flif, apng2flif, raw2flif, ...), and a simple image/animation viewer (viewflif).
- FXT
- 'FXT' is a C++ library containing code for various fast orthogonal transforms and related algorithms for real, complex, n-dim fourier transforms, hartley transform, 1dim and 2dim, number theoretic transforms, walsh, haar, and wavelet transforms, convolution, correlation and power spectrum, mass-storage FFTs and convolution, fast multiplication routines, sine and cosine transforms, and z-transform.
- Factory C
- Factory C is Factory C because it uses a factory table that uses a strategic factory method(s) thats the singleton class factory method to the class interface heap for a factory table class. There are 3 levels of OOP in Factory C and thats Virtual, Factory, and Complex. The Complex object uses a runtime object for its interface inside of its own builder table and heap containers for its class interface heap and class information heaps, and runtime objects for its interface registrations. This (Factory C) is for fully dynamic-at-runtime Object-Oriented Programming with no limitations on things like datatypes or multiple inheritance or coupling. As a presentation of hash tables or data structures Factory C uses a Virtual Table, Factory Table, and an Adapter Table. there is a single linked list template you can typename, also a vector and binary search tree (heap). but only the datastructures needed to implement Factory C are included. Also, part or the Object-Orientation of Factory C is that every primitive type has a constructor plus interface as a virtual table object and factory method plus interface heap as a factory table class. The Complex object is created using a small class builder that is implemented in C.

- Fftw
- C subroutine library for computing the Discrete Fourier Transform in one or more dimensions, of both real and complex data, and of arbitrary input size. The FFTW team's benchmarks, performed on a variety of platforms, show that FFTW's performance is typically superior to that of other publicly available FFT software. Moreover, FFTW's performance is portable: the program will perform well on most architectures without modification. However, FFTW appears to be the fastest program most of the time for in-order transforms, especially in the multi-dimensional and real-complex cases.

- Flate
- This is a candidate for deletion: Links broken. No links to page. Email to maintainer broken. Poppy-one (talk) 03:41, 31 July 2018 (EDT) Flate is a template library used to deal with HTML code in CGI applications. It includes C and Perl support. All HTML code is put in an external file (the template) and printed using the library functions: variables, zones (parts to be displayed or not), and tables (parts to be displayed 0 to n times). You don't need to modify/recompile your application when modifying HTML code, printing order doesn't matter in your CGI code, and your CGI code is cleaner.
- Fontconfig
- fontconfig is a library for customizing and configuring fonts in a system, providing configuration, enumeration and substitution of fonts to other programs.
Applications can use fontconfig in two ways:
- by querying it for the available fonts on the system, or
- by querying it for a font matching certain parameters (comprising a pattern) as closely as possible.
Features
fontconfig can:
- discover new fonts when installed automatically, removing a common source of configuration problems.
- perform font name substitution, so that appropriate alternative fonts can be selected if fonts are missing.
- identify the set of fonts required to completely cover a set of languages.
- have GUI configuration tools built as it uses an XML-based configuration file (though with autodiscovery, we believe this need is minimized).
- efficiently and quickly find the fonts you need among the set of fonts you have installed, even if you have installed thousands of fonts, while minimizing memory usage.
- be used in concert with the X Render Extension and FreeType to implement high quality, anti-aliased and subpixel rendered text on a display.
fontconfig does not:
- render the fonts themselves (this is left to FreeType or other rendering mechanisms)
- depend on the X Window System in any fashion, so that printer only applications do not have such dependencies

FormAlchemy will try to figure out what kind of HTML code should be returned by introspecting the model's properties and generate ready-to-use HTML code that will fit the developer's application. Of course, FormAlchemy can't figure out everything, i.e, the developer might want to display only a few columns from the given model. Thus, FormAlchemy is also highly customizable.

Here is an overview of the GNOME platform libraries, accessible using G-Golf. In particular, libadwaita provides a number of widgets that change their layout based on the available space. This can be used to make applications adapt their UI between desktop and mobile devices. The GNOME Web (best known through its code name, Epiphany, is a good example of such an adaptive UI. G-Golf uses Glib, GObject and GObject Introspection. As it imports a Typelib (a GObject introspectable library), G-Golf defines GObject classes as GOOPS (the Guile Object Oriented System) classes. GObject methods are defined and added to their corresponding generic function. Simple functions are defined as scheme procedures.

- GLTT
- 'GLTT' is a library that allows you to read and draw TrueType fonts in any OpenGL application. It supports bitmapped and anti-aliased font drawing as well as vectorized and polygonized drawing.
- GMM
- The Guarded Memory Move tool is useful for studying buffer overflows and catching them together with a "good" stack image. Once a stack overflow has been exploited, the back trace is already gone, as is information about parameters and local variables that are very important in understanding how the attacker is working out the exploit. The GMM library uses dynamic function call interception to catch the most common functions that attackers use to exploit stack buffers. It uses the LD_PRELOAD capability and offers two services: first, it avoids buffer overflow to allow the attacker to execute shell-code on your machine. Second, where an exploit is detected, it saves the stack content and triggers a segmentation fault. The resulting core dump has the necessary information to debug the exploit and fix the software.
- GNUe Common Library
- GNUe Common Library is the basis for the GNUe tools, such as Forms, Reports, Application Server, and Designer. It implements a database-abstraction layer that provides support for most major databases.
