How to generate characters by a function which works like the Esc + a + ESC

In[24]:= CharacterRange["a","z"]
Out[24]= {a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z}

How to batch convert them to Greek Letters just like that done by this way Esc + a + Esc ... something like this, a function works,

In[25]:= CharacterRange["\[Alpha]","\[Zeta]"]
Out[25]= {\[Alpha],\[Beta],\[Gamma],\[Delta],\[CurlyEpsilon],\[Zeta]}

EnglishToGreekRange["a", "z"]

Comes out

{\[Alpha],\[Beta],\[Chi]...}

That's a good question, though perhaps difficult to answer. The input aliases for these letters are stored not in the InputAliases option of the $FrontEnd object but rather in the UnicodeCharacters.tr file. Surely they are loaded into the Front End but I do not know the location of that data, and as such I cannot think of a clean way to access that mapping. Perhaps someone like John Fultz will take the time to answer this question and provide the correct look-up method.

If it is acceptable to allow conversion of only the Greek letters than could be accomplished by manually building a conversion table. Here is such a table for your convenience:

aliastable = 
 {"a" -> "α", "b" -> "β", "g" -> "γ", "d" -> "δ", "e" -> "ϵ", "z" -> "ζ",
 "et" -> "η", "th" -> "θ", "i" -> "ι", "k" -> "κ", "l" -> "λ", "m" -> "μ",
 "n" -> "ν", "x" -> "ξ", "om" -> "ο", "p" -> "π", "r" -> "ρ", "s" -> "σ",
 "t" -> "τ", "u" -> "υ", "ph" -> "ϕ", "ch" -> "χ", "ps" -> "ψ", "o" -> "ω",
 "di" -> "ϝ", "ko" -> "ϟ", "sti" -> "ϛ", "sa" -> "ϡ", "A" -> "Α", "B" -> "Β",
 "G" -> "Γ", "D" -> "Δ", "E" -> "Ε", "Z" -> "Ζ", "Et" -> "Η", "Th" -> "Θ",
 "I" -> "Ι", "K" -> "Κ", "L" -> "Λ", "M" -> "Μ", "N" -> "Ν", "X" -> "Ξ",
 "Om" -> "Ο", "P" -> "Π", "R" -> "Ρ", "S" -> "Σ", "T" -> "Τ", "U" -> "Υ",
 "cU" -> "ϒ", "Ph" -> "Φ", "Ch" -> "Χ", "Ps" -> "Ψ", "O" -> "Ω", "Di" -> "Ϝ",
 "Ko" -> "Ϟ", "Sti" -> "Ϛ", "Sa" -> "Ϡ"};

Now:

CharacterRange["a", "z"] /. aliastable

You can access a limited set of additional input aliases, including user-created ones, with:

CurrentValue["InputAliases"]

Here is a larger table with every letter in the Special Characters palette:

bigtable = {"a" -> "α", "b" -> "β", "g" -> "γ", "d" -> "δ", "e" -> "ϵ", "z" -> "ζ", "et" -> "η", "th" -> "θ", "i" -> "ι", "k" -> "κ", "l" -> "λ", "m" -> "μ", "n" -> "ν", "x" -> "ξ", "om" -> "ο", "p" -> "π", "r" -> "ρ", "s" -> "σ", "t" -> "τ", "u" -> "υ", "ph" -> "ϕ", "ch" -> "χ", "ps" -> "ψ", "o" -> "ω", "di" -> "ϝ", "ko" -> "ϟ", "sti" -> "ϛ", "sa" -> "ϡ", "A" -> "Α", "B" -> "Β", "G" -> "Γ", "D"

Cases[nb, {_[_[str1_String, ___], ___], _String, 
   str2_String?(StringMatchQ[#, "*\[EscapeKey]*\[EscapeKey]*"] &)} :> (StringTake[
     str2, {3, -3}] -> str1), -1]

Updated extraction code for the Mathematica 10.0.2 palette:

  • $\begingroup$ It's ok, for a mannualy conversion rules is easily to build via get all these greek letter not by just typing them. Thanks. $\endgroup$ May 16 '13 at 9:03
  • $\begingroup$ @HyperGroups I'm glad this helps you. If you use the bigtable you should probably hit it with Dispatch for best performance. $\endgroup$

Here's a function that might help:

Clear[escapify];
Attributes[escapify] = {Listable};
escapify[s_String] :=
  NotebookWrite[SelectedNotebook[], StringJoin[
    "\\" <> "[AliasDelimiter]" <> # <> "\\" <> "[AliasDelimiter]" & /@ Characters[s]]];

This takes each character in a string (or list of strings) and puts it into a new cell with escapes around it. When you type ESC in the front-end, Mathematica turns it into an \[AliasDelimiter]. This function splits of the slash from the front so the front end doesn't try to interpret it until it's written into the new cell.

escapify[CharacterRange["a", "z"]];

  • $\begingroup$ I don't know that I can. The thing is I don't really understand when/how the conversion is made. For example, this doesn't work, but it is immediately converted if you start editing the output cell: CellPrint@Cell[RowBox@{StringJoin[{"\[AliasDelimiter]", "a", "\[AliasDelimiter]"}]}, "Input"]; from this I thought the input had to be interactive but as I said NotebookWrite is a nice work-around. I don't know how to use that without actually generating output though, which I see as undesirable. $\endgroup$
