wrap is a filter for reformatting text by wrapping and filling lines to a given line-width. It is like fmt(1) or fold(1) but has many more options including, but not limited to, those for indenting (with either tabs, spaces, or both), hang indenting (with either tabs, spaces, or both), mirroring (equal left and right margins), when to delimit paragraphs, and title lines. It also fully supports the UTF-8 encoding of Unicode and additionally can reformat Markdown text.

It also includes wrapc that is useful for reformatting comments while editing source code in languages including (but not limited to if others do comments similarly): Ada, AppleScript, Assembly, AWK, C, C#, C++, Chapel, Clojure, CMake, COBOL, Crystal, D, Dart, Delphi, Eiffel, Erlang, F#, Forth, Fortran, Go, Haskell, Java, Julia, Kotlin, Lisp, Lua, Make, Mathematica, Matlab, Maxima, Metafont, ML, Modula-[23], Nim, Oberon, Objective C, Octave, OCaml, Pascal, Perl, Pike, PL/I, PostScript, PowerShell, Prolog, Pure, Python, R, Racket, Ruby, Rust, Scala, Scheme, Shell, Simula, SQL, Swift, Tcl, TeX, VHDL, XQuery, and Zig.

The git repository contains only the necessary source code. Things like configure are derived sources and should not be included in repositories. If you have autoconf, automake, and m4 installed, you can generate configure yourself by doing:

./bootstrap

Then follow the generic installation instructions given in INSTALL.

If you would like to generate the developer documentation, you will also need Doxygen; then do:

make doc                            # or: make docs
