See those two pins? Well today I'm going to... stick them in you.


Ok, let me come clean: Mr.Wizard is actually an alias of mine... I'm glad I can finally confess. ― Sjoerd C. de Vries

No, I'm Spatac... I mean, Mr.Wizard! ― R.M

I'm Mr.W, and so's my wife! ― acl


@Spartacus, it was not fixable. ― rcollyer

check again; I just fixed it. :-p ― Spartacus

It's not that easy to do the untangling even manually though. – Szabolcs

Maybe you could turn it into a puzzle and let other people do the untangling :-) – Heike

I could make a web based game, and feed all my graphs to the visitors.
SE is a big game, isn't it? :D – Szabolcs

I was tempted to edit your title: "Do rules rule?" But my nose is still bleeding as a result of a limerick. – belisarius


No, but they nowadays let me turn off the lights at night; 24 hours of fluorescence was really starting to make me feral. Brett says I should also mention the tip jar... – Daniel Lichtblau Mar 13 '12 at 20:48

@Szabolcs I would like to close and merge this as a duplicate of (13656) to keep all relevant answers in one place. That question could be edited to be more general of necessary. Do you agree?

comment How to parse string to expression?
This doesn't make sense. Your UPDATE 2 now reads as if a // ToExpression is your solution. I am sorry but I am going to stop trying to understand this problem. Perhaps someone else will have an easier time interpreting your needs. :-/

comment How to parse string to expression?
Yes, but you did not provide it in Mathematica code therefore one cannot tell what parts of it are Strings and what parts are not, etc.

comment How to parse string to expression?
The input shown in UPDATE 2 is not a String. Your output is still ambiguous, unless you actually want a bitmap image as output. Please provide the real input and real output that you want it to produce.

2/3 cm contains cm which would be parsed as a Symbol; {1, 2, 3} would be parsed as a List; is this correct? Please see my comment below the answer also.

@SuTron I repeat: it is not clear what you want to do. str starts as a string, so how can it be the output also? Are you trying to evaluate mathematical expressions within a string and replace them in the string with their evaluated forms?

comment How to parse string to expression?
Regarding the update are all the elements of the "string only" part valid Symbols, while the other contains elements that are not Symbols? If so we can use that to separate the types. If not this needs further clarification.

comment How to parse string to expression?
It is unclear what you are asking. What output do you expect? If you want to avoid the sorting due to Orderless on Times you will need a hold function, e.g. ToHeldExpression or MakeExpression. (Or to hide the hold function ToExpression[str, StandardForm, HoldForm].) However these may still not do what you want, whatever that is, as other kinds of parsing still take place.
