The cron command-line utility is a job scheduler on Unix-like operating systems.Users who set up and maintain software environments use cron to schedule jobs [1] (commands or shell scripts), also known as cron jobs, [2] [3] to run periodically at fixed times, dates, or intervals. [4]
Write once, compile anywhere (WOCA) is a philosophy taken by a compiler and its associated software libraries or by a software library/software framework which refers to a capability of writing a computer program that can be compiled on all platforms without the need to modify its source code. As opposed to Sun's write once, run anywhere slogan ...
VisualCron is a replacement for the Windows Task Scheduler and a similar cron job scheduler in Unix-like operating systems. [1] The software is split into client and server parts, with the former being invoked by the user on demand and the latter always running as a process in the background. [1]
A multi-pass compiler is a type of compiler that processes the source code or abstract syntax tree of a program several times. This is in contrast to a one-pass compiler, which traverses the program only once. Each pass takes the result of the previous pass as the input, and creates an intermediate output.
Using #pragma once allows the C preprocessor to include a header file when it is needed and to ignore an #include directive otherwise. This has the effect of altering the behavior of the C preprocessor itself, and allows programmers to express file dependencies in a simple fashion, obviating the need for manual management.
Code::Blocks is a free, open-source, cross-platform IDE that supports multiple compilers including GCC, Clang and Visual C++. It is developed in C++ using wxWidgets as the GUI toolkit. Using a plugin architecture, its capabilities and features are defined by the provided plugins. Currently, Code::Blocks is oriented towards C, C++, and Fortran.
Compiled Java code files are generally smaller than code files in C++ as Java bytecode is usually more compact than native machine code and Java programs are never statically linked. C++ compiling features an added textual preprocessing phase, while Java does not. Thus some users add a preprocessing phase to their build process for better ...
Once they had improved the compiler to the point where it could compile its own source code, it was self-hosting. [ 9 ] The compiler as it exists on the standard compiler tape is a machine language program that was obtained by having the S-expression definition of the compiler work on itself through the interpreter.
