w3s: terminal-based web browser & pager

This repository is for the continued development of the w3m web browser and pager, since upstream seems to have died down. It is based on w3m 0.5.3, released 2011-01-15.

w3s is ideal for browsing content-focused websites where the clutter displayed by graphical web browsers gets in the way of the actual content.

It currently runs on OpenBSD, and compiles using BSD make.

Features

Protocols: HTTPS, HTTP, FTP, Gopher
Renders tables, hyperlinks, forms, lists, horizontal rules, headings, images (in xterm, using imlib2).
vi(1)-like control scheme
Support for multiple character encodings: UTF-8, Shift_JIS, Big5, KOI8-R, etc (see charset-list)
and cookies.

Changes since 0.5.3

NULL pointer dereference and buffer overflow bugs fixed.
Format string fixes (including Y2038 fixes).
Inserted checks for integer overflow in allocation functions.
Use asprintf() to implement gc-based Sprintf() instead of hand-rolled evilness.
Thousands of lines of code removed:
- Support for old revisions of POSIX and DOS is gone.
- Usenet (NNTP) support has been removed.
- Improperly licensed MATRIX table rendering code that wasn't doing anything useful beyond the non-MATRIX code.
- Unused character encodings (UTF-7, Johab...)
- Replacements for standard interfaces (curses, C library stuff...)
Use modern C features (size_t, const, enums, snprintf, memcpy instead of bcopy, etc).
Formatted the code to a more readable style where every block is indented.
Improved Gopher support.

Building and installing

OpenBSD

# pkg_add boehm-gc imlib2
# make
# make install
$ w3s https://en.wikipedia.org

Additionally, it's possible to build without m17n and/or image support:

# pkg_add boehm-gc
# USE_IMAGE=no USE_M17N=no make
# make install
$ w3s https://en.wikipedia.org
