EVAL!

picol_expr

double picol_expr(struct picol_interp * i, char ** p, int * err, int prec)

Defined at mopscript.c#582

This is a "Pratt style parser" for expressions: precedence is encoded in a single recursive function. Basically the C call stack replaces the explicit stack here.

Precedences: 0 ||, 1 &&, 2 comparisons, 3 add/sub, 4 mul/div, 5 unary.

Note: picolExpr() is designed to be simple, not fully functional, so it does not expand $vars and [commands]. [expr $a + [foo]] works, but [expr {$a + [foo]}] will not. Also: no short circuits with && ||

picol_expr_expansion

int picol_expr_expansion(struct picol_interp * i, char * s)

Defined at mopscript.c#718

Trick: wrap 's' as "expr s" and evaluate it, so that picolEval handles $var and [cmd] substitution before expr parses pure math expression. This is used in [if] and [while] condition evaluation.

Defined at mopscript.c#729

Defined at mopscript.c#738
