ROSE: an open source compiler framework to generate source-to-source analyzers and translators for C/C++ and Fortran, developed at Lawrence Livermore National Laboratory MILEPOST GCC : interactive plugin-based open-source research compiler that combines the strength of GCC and the flexibility of the common Interactive Compilation Interface that ...
the invocation of a compiler together with source to compile and instructions for executing the compiled program. Certain dynamic languages for scripting, such as AWK, sed, and Perl, have traditionally been adept at expressing one-liners. Shell interpreters such as Unix shells or Windows PowerShell allow for the construction of powerful one-liners.
Documentation – Unix was one of the first operating systems to include all of its documentation online in machine-readable form. [32] The documentation included: man – manual pages for each command, library component, system call, header file, etc. doc – longer documents detailing major subsystems, such as the C language and troff
Yacc (Yet Another Compiler-Compiler) is a computer program for the Unix operating system developed by Stephen C. Johnson.It is a lookahead left-to-right rightmost derivation (LALR) parser generator, generating a LALR parser (the part of a compiler that tries to make syntactic sense of the source code) based on a formal grammar, written in a notation similar to Backus–Naur form (BNF). [1]
A one-pass compiler initially has to leave addresses for forward jumps unresolved. These can be handled in various ways (e.g. tables of forward jumps and targets) without needing to have another complete pass. One-pass compilers are smaller and faster than multi-pass compilers. [1]
Make is widely used, especially in Unix and Unix-like operating systems, even though many competing technologies and tools are available including: similar tools that perform actions based on dependencies, some compilers and interactively via an integrated development environment.
bs is a programming language and a compiler/interpreter for modest-sized programs on UNIX systems. [1] The bs command can be invoked either for interactive programming or with a file containing a program, optionally taking arguments, via a Unix shell, e.g., using a Shebang (Unix) #!/usr/bin/bs.
Johnson joined Bell Labs and AT&T in the 1960s and worked on Unix tools for nearly 20 years, alongside computer scientists like Jeffrey Ullman, Dennis Ritchie and Alfred Aho. He was best known for writing Yacc, Lint, and the Portable C Compiler. In the mid-1970s, Johnson and Bell colleague Dennis Ritchie co-authored the first AT&T Unix port.
