# Slackware build script for evince-gtk2

# Originally written by Petar Petrov.
# Modified and now maintained by B. Watson <urchlay@slackware.uk>

# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.

# 20250924 bkw, BUILD=3:
# - add a patch from MadMaverick9 to stop evince segfaulting on
#   exit when viewing "optimized/linearized" PDFs.
# - fix NLS --disable/--enable args.
# - explain why NLS=no is the default in README.

# 20240819 bkw, BUILD=2:
# - new maintainer.
# - relicense as WTFPL.
# - disable NLS by default, mention NLS=yes in the README.
# - enable DVI backend, since Slackware 15.0 has texlive.
# - remove mention of XPS from README, since this older version
#   of evince doesn't actually support it.
# - make comic book support (CBZ/CBR/CB7/CBT) actually *work*.

# 20250924 bkw: MadMaverick9 from IRC sent me this patch.
# The 'linearized' struct member is declared as a string and assigned
# a boolean value (0 or 1). Then on exit, gfree(linearized) was being
# called, which didn't hurt anything when linearized was false (aka
# 0) due to the real free() having a NULL check. But calling it when
# true results in free(1), which it doesn't check for. Result: *Boom*,
# segfault!
# Linearized (aka 'optimized') PDFs have always been fairly rare, and
# were really only (mildly) useful on slow dialup lines. You could see
# the first page of the PDF before the rest was downloaded. Of course
# that's usually useless since it's generally just a cover or title page.
# It might be worth mentioning that mupdf just recently dropped support
# for linearized PDFs, too.

# 20240819 bkw: add the correct MIME types for CBZ/CBR/CB7/CBT to actually

# if shared-mime-info and friends detect e.g. a .cbr file as application/x-cbr
# instead of application/vnd.rar as 15.0's does.
