There is no reason to install this package on its own.

Clang project is a C, C++, Objective C and Objective C++ front-end based on the LLVM compiler. Its goal is to offer a replacement to the GNU Compiler Collection (GCC).

QGIS is a Geographic Information System (GIS) which manages, analyzes and display databases of geographic information.

The gsubfn function is like gsub but can take a replacement function or certain other objects instead of the replacement string. Matches and back references are input to the replacement function and replaced by the function output. gsubfn can be used to split strings based on content rather than delimiters and for quasi-perl-style string interpolation. The package also has facilities for translating formulas to functions and allowing such formulas in function calls instead of functions. This can be used with R functions such as apply, sapply, lapply, optim, integrate, xyplot, Filter and any other function that expects another function as an input argument or functions like cat or sql calls that may involve strings where substitution is desirable. There is also a facility for returning multiple objects from functions and a version of transform that allows the RHS to refer to LHS used in the same transform.

A program that computes structure factors |F^2| for neutrons, x-rays, and electrons from CIF/CFL/SHX/PCR crystallographic descriptions. This is useful to compute the diffraction pattern from materials.

nextpnr is a FPGA place and route tool. Its purpose is to turn a topological description of digital hardware produced by an FPGA logic synthesis tool such as yosys into an elaborate map of connections between the hardwired functional units available inside the FPGA's fabric.
