test:
[smiley=integral.gif] x2 dx [smiley=larrow.gif] [smiley=infty.gif]
[infty][int]
Code:
[smiley=integral.gif] x[sup]2[/sup] dx [smiley=larrow.gif] [smiley=infty.gif]
[infty][int]

check out http://us.metamath.org/symbols/symbols.html for the full list of symbol codes.

i'll resume tomorrow. let me know if aspects of the forum which normally work properly no longer do; by modifying existing code i may have introduced new bugs

Fantastic! Be sure to add codes for [smiley=pi.gif] and [smiley=partial.gif]. (I see these two will need some trimming to bring the down to the line.) Thanks! This is cool!

[pi] and [partial] symbols added to drop down menu. yes, this is definitely very cool

test:
using ascii letters for variables:
lim(n[to][infty]) [sum]i=1,..,nX[subi][supi] = lim(n[to][infty]) X[sub0][sup0] + X[sub1][sup1] + ... + X[subn][supn] [to] [pi]
Code:
lim(n[to][infty]) [sum][sub]i=1,..,n[/sub]X[subi][supi] = lim(n[to][infty]) X[sub0][sup0] + X[sub1][sup1] + ... + X[subn][supn] [to] [pi] |
|
=============================
using GIF letters [smiley=r.gif], [smiley=n.gif] and [smiley=cx.gif] (cx.gif):
lim([smiley=n.gif][to][infty]) [sum]i=1,..,n[smiley=cx.gif][subi][supi] = lim([smiley=n.gif][to][infty]) [smiley=cx.gif][sub0][sup0] + [smiley=cx.gif][sub1][sup1] + ... + [smiley=cx.gif][subn][supn] [to] [pi]
Code:
lim([smiley=n.gif][to][infty]) [sum][sub]i=1,..,n[/sub][smiley=cx.gif][subi][supi] = lim([smiley=n.gif][to][infty]) [smiley=cx.gif][sub0][sup0] + [smiley=cx.gif][sub1][sup1] + ... + [smiley=cx.gif][subn][supn] [to] [pi] |

hmm. it looks like everything works out if we use the images completely when writing equations. however, that would be too annoying.

test material for trimming:

trimming done. some of the symbols still look a bit off (e.g. magnitude bars), but that's the best i can do unless i modify non-blank area on the images, which is more work than i'd like to do right now

"view all symbols" script fixed
