Make chemistry equations look different with Unicode


I made a small program (23 KB) to make chemical equations somewhat look better.

It turns this:

2MnO4 - + SO3 2- + 2OH- --> 2MnO4 2- + SO4 2- + H2O

into this:

2MnO₄⁻ + SO₃²⁻ + 2OH⁻ → 2MnO₄²⁻ + SO₄²⁻ + H₂O

by using a bunch of RegEx and Unicode. (Had to increase size a bit 'cause it was kind of small.)

If anyone wants to try it out, here is a download link: http://www.mediafire.com/file/aesa60r6c2w4e41/ChemistryInlin... (Just in case if the upload here does not work.)

If anyone wants to extend it, here is the important part of the source code (language is VB):

Code:
Private Sub Convert() Dim Str1 As String = TextBox1.Text Str1 = " " + Str1.TrimEnd(" ") Str1 = Regex.Replace(Str1, "[<]+[-‒–—―=]*[>]+", "↔") Str1 = Regex.Replace(Str1, "[-‒–—―=]*[>]+", "→") Str1 = Regex.Replace(Str1, "(?<!\s\d*)0(?!\d*[+-]+)", "₀") Str1 = Regex.Replace(Str1, "(?<!\s\d*)1(?!\d*[+-]+)", "₁") Str1 = Regex.Replace(Str1, "(?<!\s\d*)2(?!\d*[+-]+)", "₂") Str1 = Regex.Replace(Str1, "(?<!\s\d*)3(?!\d*[+-]+)", "₃") Str1 = Regex.Replace(Str1, "(?<!\s\d*)4(?!\d*[+-]+)", "₄") Str1 = Regex.Replace(Str1, "(?<!\s\d*)5(?!\d*[+-]+)", "₅") Str1 = Regex.Replace(Str1, "(?<!\s\d*)6(?!\d*[+-]+)", "₆") Str1 = Regex.Replace(Str1, "(?<!\s\d*)7(?!\d*[+-]+)", "₇") Str1 = Regex.Replace(Str1, "(?<!\s\d*)8(?!\d*[+-]+)", "₈") Str1 = Regex.Replace(Str1, "(?<!\s\d*)9(?!\d*[+-]+)", "₉") Str1 = Regex.Replace(Str1, "((?<=\s\d+)[+]|(?<=\s)[+](?=\s*[+-]+)|(?<=\s+)[+]$|(?<=[A-Za-z])[+])", "⁺") Str1 = Regex.Replace(Str1, "((?<=\s\d+)[-]|(?<=\s)[-](?=\s*[+-]+)|(?<=\s+)[-]$|(?<=[A-Za-z])[-])", "⁻") Str1 = Regex.Replace(Str1, "\s+0(?=[⁺⁻]+)", "⁰") Str1 = Regex.Replace(Str1, "\s+1(?=[⁺⁻]+)", "¹") Str1 = Regex.Replace(Str1, "\s+2(?=[⁺⁻]+)", "²") Str1 = Regex.Replace(Str1, "\s+3(?=[⁺⁻]+)", "³") Str1 = Regex.Replace(Str1, "\s+4(?=[⁺⁻]+)", "⁴") Str1 = Regex.Replace(Str1, "\s+5(?=[⁺⁻]+)", "⁵") Str1 = Regex.Replace(Str1, "\s+6(?=[⁺⁻]+)", "⁶") Str1 = Regex.Replace(Str1, "\s+7(?=[⁺⁻]+)", "⁷") Str1 = Regex.Replace(Str1, "\s+8(?=[⁺⁻]+)", "⁸") Str1 = Regex.Replace(Str1, "\s+9(?=[⁺⁻]+)", "⁹") Str1 = Regex.Replace(Str1, "\s+(?=[₀₁₂₃₄₅₆₇₈₉]*[⁺⁻])", "") TextBox2.Text = Str1.TrimStart(" ") End Sub


To anyone better in programming this probably looks horrible ;)

Have fun!

Cheers

Hi,
I found this, which may also be of some use.

I hope it's of some use to everyone. :)

chemsketch requires registration and the word "mandatory" is anathema to moi. It just seems to me that limit notation is part of the history and theory and is itself limited as has been mentioned. I guess I'm prejudiced because I use mostly partials. And rarely do physics. But I have explained calculus using the concept of limits and have reminded myself how it all works by writing out the ideas with limit notation.

A bit nonsequential, chemrox. It seems like you are answering several threads at once.

I downloaded and use chemsketch. No registration was required. This might be a recent change. Avogadro is similar but not as powerful.

Limit notation in calculus, or more accurately, analysis -- seems an ok way to write the concept. Or, more to the point, if you understand the concept, the notation is pretty efficient. Beginning with the notation and then trying to insert the concept is a way to introduce confusions, but that is a pedagogical issue and not unique to limits at all.

Liebniz notation does have advantages over function notation but I think I sumarised the position in the other thread.
The registration screen do occur to me
