# Possible targets:
#
#   ttf    Generate TrueType files with ttfautohint.
#   html   Generate HTML pages (this also needs generated TTF files).
#   png    Generate PNG images from HTML pages via browserstack.
#
#   all    Make `ttf', `html', and `png' targets.  Note that target `all'
#          makes only sense if the files generated by `html' are immediately
#          available from the web so that browserstack can access them.
#          Otherwise, you have to call target `html', upload the created
#          files to a suitable host – with the default setup below this
#          simply means committing the new files to the repository –, then
#          finishing with target `png'.

# The directory where the sample texts are stored.  The name of the files
# must be of the form `<lang>-<script>_$(SAMPLE_TEXT_SUFFIX)', where <lang>
# is a two-letter or three-letter tag (given as the fourth argument to the

# Example: `ar-Arab_uhdr.txt'.

# The URL prefix to access HTML pages for the repository we are going to
# fill with created files.  Note that directly accessing `github.com'
# doesn't work since HTML pages (intentionally) get a `Content-Type' of
# `text/plain'.

# Hinting modes for ttfautohint.  This sets ttfautohint option `-w'.  The
# modes are also added as a suffix to both the output font name (ttfautohint
# option `-F') and the output font's file name (via Makefile rules).
#
# `G' means strong hinting for GDI ClearType only, `gGD' indicates strong
# hinting for all hinting modes (grayscale, GDI, and DWrite ClearType).
#
# Two values are special: `manual' and `unhinted'.  They are not options for
# ttfautohint; instead, they refer to already existing fonts located in the
# directories given by `HINTED_FONT_DIR' and `UNHINTED_FONT_DIR',
# respectively.
#
# This Makefile generates separate HTML test pages for each value in
# `HINTING_MODES'.

# The browsers, as set up in the `*.yaml' files, which are also used by
# browserstack for `*.png' snapshot file names.
#
# Note that IE 11 on Win 8.1, as provided by browserstack, has a bug that
# prevents usage of cross-site web fonts.  In other words, `unhinted' and
# `manual' hinting modes usually show Windows system fonts instead of the
# ones linked from `UNHINTED_FONT_URL' and `HINTED_FONT_URL'.
