math symbol: blacktriangle

math symbol: blacktriangle

[Andreas Mang]

Dear all,

The \blacktriangle and \blacktriangledown symbol seem to be missing, though \blacktriangleright and \...-left are defined. Is there a quick way to add missing symbols by myself from the knowledge of Unicode / XML identifier (http://www-sop.inria.fr/marelle/tralics/doc-b.html)?

Cheers,
Andreas

For opentype math fonts, have a look at char-def.lua. To add missing 
symbols, you need to add appropriate fields in the lua table.

The hard part is verifying the symbol to unicode slot mapping (the list at 
tralics is not always consistent with the ams list that is used by 
unicode-math package). If you know the right mappings, add a patch to 
char-def.lua and send it to the list (or the dev-context list); otherwise, 
just send the mappings and I can add them to the lua table.

Re: math symbol: blacktriangle

[Andreas Mang]

Hi Aditya,

Thanks for the advice. As I am a newby, I'd decided to respond to the list:

I had a look at "char-def.lua" and I think the only thing that needs to be done is to add

mathname="blacktriangle",

to

[0x25B4]={
  adobename="blackuppointingsmalltriangle",
  category="so",
  description="BLACK UP-POINTING SMALL TRIANGLE",
  direction="on",
  linebreak="al",
  unicodeslot=0x25B4,
 },


The unicodeslot is consistent to what I've found in the famous WWW

http://www.fileformat.info/info/unicode/char/25b4/index.htm


Same goes for

 [0x25BE]={
  category="so",
  description="BLACK DOWN-POINTING SMALL TRIANGLE",
  direction="on",
  linebreak="al",
  unicodeslot=0x25BE,
 },

with mathname="blacktriangledown" under the assumption you'd like to be consistent with the naming convention of latex.

Right?

Cheers,
Andreas

keep in mind that not all those black triangles in ams math ended up in 
unicode

(future lm/gyre fonts might have some of these symbols)

AFAIK all ams symbols are in Unicode now (I know because the STIX LaTeX
support covers them all from STIX Unicode fonts).

Also the black triangles left and right (in ams compatible font sizes)?

(Last time I messed with it I had to get them from the navigational 
symbol font).

why not 25B2 (the bigger one)

To make it short: I think Hans is correct. From my perspective there is an error in char-def.lua for "blacktriangleleft" and secondly the internet page I have looked this up is not consistent with what is implemented in ConTeXt, both facts of which lead me into the wrong direction (see below (P.S.), if you are interested).

Both,

http://www.unicodemap.org/details/0x25B2/index.html

and

http://www.unicodemap.org/details/0x25BC/index.html

look consistent to "\blacktriangleright" (which I am already using in my document):

http://www.unicodemap.org/details/0x25B6/index.html

Cheers,
Andreas


P.S.: When I started to look into this I thought it might be possilble to define some command in the preamble of my document that uses unicode. From searching the internet I found 

http://www-sop.inria.fr/marelle/tralics/doc-b.html

which says "The \blacktriangle command is valid only in math mode. Its translation is <mo>&blacktriangle;</mo> (Unicode U+25B4, ▴)".

However, there indeed is a problem (which I have not spotted in the first place). I had a look at char-def.lua which at first confirmed my impression on using small triangels: 

 [0x25B8]={
  category="so",
  description="BLACK RIGHT-POINTING SMALL TRIANGLE",
  direction="on",
  linebreak="al",
  mathclass="bin",
  mathname="blacktriangleleft",
  unicodeslot=0x25B8,
 },

However, this is not consistent with what you can find on the internetpage from above, since it "0x25B8" should be "blacktriangleright" 

"The \blacktriangleright command is valid only in math mode. Its translation is <mo>&blacktriangleright;</mo> (Unicode U+25B8, ▸)." 

Secondly, the \triangleleft, which I have not used before, does not work (at least for me ConTeXt  ver: 2012.07.10 09:52 MKIV fmt: 2012.7.15 int: english/english):

simple example: 

%%%%%%%%%%%%
\starttext
$\blacktriangleleft$ % does not appear
$\blacktriangleright$ % works
\stoptext
%%%%%%%%%%%%

For the blacktriangleright we have:

 [0x25B6]={
  adobename="blackrightpointingtriangle",
  category="so",
  cjkwd="a",
  description="BLACK RIGHT-POINTING TRIANGLE",
  direction="on",
  linebreak="ai",
  mathclass="bin",
  mathname="blacktriangleright",
  unicodeslot=0x25B6,
 },

which is _not_ consistent with "The \blacktriangleright command is valid only in math mode. Its translation is <mo>&blacktriangleright;</mo> (Unicode U+25B8, ▸)."

However, looking at http://www.unicodemap.org/details/0x25B6/index.html and given the fact that "blacktriangleright" works nicely, I'd assume that Hans is correct and it indeed is not the small ones but the big tirangles.

Hi,

Thanks Hans. It works for me :) Relating the output (\blacktriangleright and \blacktriangle) to some figure I have created with latex + tikz I do not see any difference.

I haven't checked the new beta, but FWIW, these are the slots that 
unicode-math package uses (I usually treat that as a reference):

\UnicodeMathSymbol{"025B2}{\bigblacktriangleup       }{\mathord}{black up-pointing triangle}%
\UnicodeMathSymbol{"025B3}{\bigtriangleup            }{\mathbin}{big up triangle, open}%

\UnicodeMathSymbol{"025B5}{\vartriangle              }{\mathrel}{/triangle - up triangle, open}%
\UnicodeMathSymbol{"025B6}{\blacktriangleright       }{\mathord}{(large) right triangle, filled}%
\UnicodeMathSymbol{"025B7}{\triangleright            }{\mathbin}{(large) right triangle, open; z notation range restriction}%
\UnicodeMathSymbol{"025B8}{\smallblacktriangleright  }{\mathord}{right triangle, filled}%

\UnicodeMathSymbol{"025BA}{\blackpointerright        }{\mathord}{black right-pointing pointer}%
\UnicodeMathSymbol{"025BB}{\whitepointerright        }{\mathord}{white right-pointing pointer}%
