Trivial brainfuck substitution

TrivialBrainfuckSubstitution is not a single programming language, but rather a large family of programming languages that are trivial substitutions of the brainfuck language.

Syntax

We will pick TrivialBrainfuckSubstitution("a","b","c","d","e","f","g","h") as an example. To write a program in TrivialBrainfuckSubstitution("a","b","c","d","e","f","g","h"), first make a program in brainfuck. Then, convert it to according to this table:

Brainfuck	Substitution Argument	Description
>	a	Move the pointer to the right
<	b	Move the pointer to the left
+	c	Increment the memory cell under the pointer
-	d	Decrement the memory cell under the pointer
.	e	Output the character signified by the cell at the pointer
,	f	Input a character and store it in the cell at the pointer
[	g	Jump past the matching h if the cell under the pointer is 0
]	h	Jump back to the matching g

In addition it's common to replace short sequences of brainfuck instructions with substitutions. For example [-] may be replaced by a single instruction or some form of run length encoding might be used.

Interpreter

Interpreters for these languages are also generally trivial to write using a regular expression and a lookup table to convert the language to something that can be executed directly. Two simple examples are below.

Ruby	Perl
#!/usr/bin/env ruby eval 'm=Hash.new(p=0);'+ARGF.read.gsub(/./, '>' => 'p+=1;', '<' => 'p-=1;', '+' => 'm[p]+=1;', '-' => 'm[p]-=1;', '.' => 'putc m[p];', ',' => 'm[p]=STDIN.getbyte if !STDIN.eof;', '[' => '(', ']' => ')while((m[p]&=255)!=0);')	#!/usr/bin/env perl %c=qw( > $p++; < $p--; + $b[$p]++; - $b[$p]--; . print+chr$b[$p]; , $b[$p]=ord(getc); [ $b[$p]&=255;while($b[$p]){ ] $b[$p]&=255;} ); $/=$,;$_=<>;s/./$c{$&}/g;eval
