7 years agolatin: 5-point tactile alphabet
Mischa POSLAWSKY [Sun, 26 Mar 2017 23:10:52 +0000 (01:10 +0200)]
latin: 5-point tactile alphabet

Proposal by Tmeister on http://www.incatena.org/viewtopic.php?f=4&t=41001
built for blind reading and writing similar to braille but allowing
one-handed input.

Original hexagon dots are barely distinguishable at this size, so prefer
circles for simplicity and similarity with braille.

7 years agolatin: align svg and tap code in cells

latin: align svg and tap code in cells

Assume subsequent lines are optional and should not influence positioning
(currently only for Tap simplified).

SVG images OTOH should fit the whole cell, so drop baseline alignment to
avoid bottom margin.

7 years agolatin: common styling for svg paths (lines)

latin: common styling for svg paths (lines)

SVG data is always inlined, so making it dependent on page style should not
be an issue.  Simplifies all paths to be lines unless fill is specified,
decreasing total size from 46kB to 38kB (though only 50 bytes over 4kB
compressed).

7 years agodigraphs: reclassify vim support levels

digraphs: reclassify vim support levels

Instead of custom u-* classes, reuse common l1-5 in include:

.u-di      → l4 (vim + rfc)
.u-prop    → l3 (vim)
.u-prop.ex → l2 (shiar)
.ex        → l1 (rfc only)

Prepend u- on page to avoid conflicting with script styling (leave
background colour unaltered).

Loses ascii/latin1 distinction, but clarifies (vim) compatibility and
allows for easier extension later on.

Recent versions of Vim v7.4 prepend the expected version number by various

\e[?1049h\e[?1h\e=\e[1;63r\e[?25h\e[?25h\e[?25l\e[63;1H704
