Designed and written from scratch it wraps around libwget, that provides the basic functions needed by a web client. Wget2 works multi-threaded and uses many features to allow fast operation. In many cases Wget2 downloads much faster than Wget1.x due to HTTP2, HTTP compression, parallel connections and use of If-Modified-Since HTTP header. GNU Wget2 is licensed under GPLv3+. Libwget is licensed under LGPLv3+. # Features A non-exhaustive list of features - Support for HTTP/1.1 and HTTP/2.0 protocol - [brotli](https://github.com/google/brotli) decompression support (Accept-Encoding: br) - [zstandard](https://github.com/facebook/zstd) decompression support, RFC8478 (Accept-Encoding: zstd) - [lzip](https://www.nongnu.org/lzip/) decompression support, (Accept-Encoding: lzip) - HPKP - HTTP Public Key Pinning (RFC7469) with persistent database - TCP Fast Open for plain text *and* for HTTPS - TLS Session Resumption including persistent session data cache - TLS False Start (with GnuTLS >= 3.5.0) - HTTP2 support via nghttp2 and GnuTLS ALPN including streaming/pipelining - OCSP stapling + OCSP server querying as a fallback (experimental, needs GnuTLS >= 3.3.11) - Use [libpsl](https://github.com/rockdaboot/libpsl) for cookie domain checking (using Public Suffix List) - Support link conversion (-k/--convert-links and -K/--backup-converted) - Support for RFC 6266 compliant Content-Disposition - RFC 6797 HSTS (HTTP Strict Transport Security) - Support for bzip2 Content-Encoding / Accept-Encoding compression type - New Year 2014 gimmick: added support for XZ Content-Encoding / Accept-Encoding compression type - Character encoding of input files may be specified despite from local and remote encoding (--input-encoding) - Support scanning RSS 2.0 feeds from local files (`--force-rss -i <filename>`) - Support scanning RSS 2.0 feeds. - Support scanning Atom 1.0 feeds from local files (`--force-atom -i <filename>`) - Support scanning Atom 1.0 feeds. - Support scanning URLs from local Sitemap XML file (`--force-sitemap -i <filename>`) - Support scanning sitemap files given in robots.txt (Sitemap XML, gzipped Sitemap XML, plain text) including sitemap index files. - Support arbitrary number of proxies for parallel downloads - Multithreaded download of single files (option --chunk-size) - Internationalized Domain Names in Applications (compile-selectable IDNA2008 or IDNA2003) - ICEcast / SHOUTcast support via library (see examples/getstream.c) - respect /robots.txt "Robot Exclusion Standard" and `<META name="robots" ...>` - new option --secure-protocol=PFS to have TLS only plus forcing Perfect Forward Secrecy (PFS) - IDN support for international domains - autotools support - proxy support - cookies (session/non-session), detection of supercookies via Mozilla Public Suffix List (use the new option `--cookie-suffixes <filename>`, better: put it into ~/.wgetrc) - recursive download of websites with or without spanning hosts - download of single web pages / resources - zlib/gzip compressed HTTP/HTTPS downloads (gzip, deflate) - number of parallel download threads is adjustable - include directive for config files (wildcards allowed) - support for keep-alive connections - included CSS, HTML, XML parser needed for recursive downloads - gettext support - HTTPS via libgnutls (and basic WolfSSL support) - support for Metalink RFC 6249 (Metalink/HTTP: Mirrors and Hashes) - support for Metalink RFC 5854 (Metalink Download Description Format / .meta4 files) - support for Metalink 3 - Metalink checksumming via libgnutls - DNS lookup cache - IPv4 and IPv6 support - built and tested on Linux, OSX, OpenBSD, FreeBSD, Solaris, Windows # Links [Online Docs](https://gnuwget.gitlab.io/wget2/reference/) [Mailing List](https://savannah.gnu.org/mail/?group=wget) [Bug Tracker](https://gitlab.com/gnuwget/wget2/issues) [Development](https://gitlab.com/gnuwget/wget2) [Code Coverage](https://gnuwget.gitlab.io/wget2/coverage/) [Fuzz Code Coverage](https://gnuwget.gitlab.io/wget2/fuzz-coverage/) # Build Requirements The following packages are needed to build the software * autotools (autoconf, autogen, automake, autopoint, libtool) * python (recommended for faster bootstrap) * rsync * tar * makeinfo (part of texinfo) * pkg-config >= 0.28 (recommended) * doxygen (for creating the documentation) * pandoc (for creating the wget2 man page) * gettext >= 0.18.2 * libiconv (needed for IRI and IDN support) * libz >= 1.2.3 (the distribution may call the package zlib*, eg. zlib1g on Debian) * liblzma >= 5.1.1alpha (optional, if you want HTTP lzma decompression) * libbz2 >= 1.0.6 (optional, if you want HTTP bzip2 decompression) * libbrotlidec/libbrotli >= 1.0.0 (optional, if you want HTTP brotli decompression) * libzstd >= 1.3.0 (optional, if you want HTTP zstd decompression) * libgnutls (3.3, 3.5 or 3.6) * libidn2 >= 0.14 (libidn >= 1.25 if you don't have libidn2) * flex >= 2.5.35 * libpsl >= 0.5.0 * libnghttp2 >= 1.3.0 (optional, if you want HTTP/2 support) * libmicrohttpd >= 0.9.51 (optional, if you want to run the test suite) * lzip (optional, if you want to build distribution tarballs) * lcov (optional, for coverage reports) * libgpgme >= 0.4.2 (optional, for automatic signature verification) * libpcre | libpcre2 (optional, for filtering by PCRE|PCRE2 regex) * libhsts (optional, to support HSTS preload lists) * libwolfssl (optional, to support WolfSSL instead of GnuTLS) The versions are recommended, but older versions may also work. # Downloading and building from tarball wget https://gnuwget.gitlab.io/wget2/wget2-latest.tar.gz tar xf wget2-latest.tar.gz cd wget2-* ./configure make make check sudo make install # Building from git ### Download project and prepare sources with git clone https://gitlab.com/gnuwget/wget2.git cd wget2 ./bootstrap # on shell failure try 'bash ./bootstrap' ### Build Wget2 with ./configure make ### In Haiku build Wget2 with setarch x86 ./configure --prefix=/boot/home/config/non-packaged rm /boot/home/config/non-packaged/wget2 && mv /boot/home/config/non-packaged/wget2_noinstall /boot/home/config/non-packaged/wget2 ### Test the functionality make check ### Install Wget2 and libwget sudo make install (or su -c "make install") ### Build static wget2.exe on GNU/Linux for Windows (cd contrib; docker build -t wget2/static -f Dockerfile.win32.static .) docker run --rm -v $PWD:/tmp wget2/static cp /usr/local/wget2/src/wget2.exe /tmp # now you have `wget2.exe` with debug symbols in your current directory # optional: remove debug symbols with strip wget2.exe # optional: pack executable upx wget2.exe # License Copyright (C) 2015-2024 Free Software Foundation, Inc.
