In any TikZ command, for example draw
, how does TikZ extract the keys, as they can be in any order.
For example, the following draw
statements, give the same output (in different locations in the 2D space though):
documentclassarticle
usepackagetikz
begindocument
tikz draw[->,red,thick,dashed] (0,0) |- (2,2);
tikz draw[->,thick,red,dashed] (3,0) |- (0,5);
enddocument
The first draw
command has the keys, red
, thick
and dashed
.
The seconddraw
command has the keys, thick
, red
and dashed
.
How does TikZ/LaTeX know, red
means color, thick
is thickness of the line.
What is the logic behind this.

The pgfkeys
package allows 'styles' to be defined as shortcuts to normal keyvals. Thus thick
is a shortcut for line width = 0.8pt
and red
is (approximately) a shortcut for draw = red
. Ultimately, which are defined is down to the pgf
implementers.
As mentioned in Problem between pgfkeys, tikz and personal macro, some of these shortcuts are not actually normal keys but are rather found on a specifically-coded path of the pgfkeys
parser. In particular, many TikZ commands attempt to treat unknown keys as colours before 'giving up'.

It turns out the color, shape names and arrow names are not actual keys possible because there are too numerous of them. Here @percusse explains how it is handled in the code.
