Detailed Description

Contains extra expression types beyond the standard ones from expr.h defined in the generic expression parser included with the parser generator.

Some of these are only used during expansion of expressions to return new result types (e.g. an array result)

Macro Definition Documentation

◆ E_ANDLOOP

#define E_ANDLOOP (E_END + 21)

used for (&i:lo..hi:expr)
expressions. l->l = id, r->l
= lo, r->r->l = hi, r->r->r = expr

◆ E_ARRAY

#define E_ARRAY (E_END + 11)

an expanded paramter array

the l field will point to the ValueIdx
the r field will point to the Scope

◆ E_BUILTIN_BOOL

#define E_BUILTIN_BOOL (E_END + 23)

for bool(x)

◆ E_BUILTIN_INT

#define E_BUILTIN_INT (E_END + 24)

for int(x) or int(x,v)

◆ E_ENUM_CONST

#define E_ENUM_CONST (E_END + 25)

used for an enumeration constant

◆ E_NEWEND

#define E_NEWEND E_END + 26

new "end" of expression options

◆ E_ORLOOP

#define E_ORLOOP (E_END + 22)

used for (|i:lo..hi:expr)
expressions. l->l = id, r->l
= lo, r->r->l = hi, r->r->r = expr

◆ E_SELF

#define E_SELF (E_END + 20)

used for "self"

◆ E_SELF_ACK

#define E_SELF_ACK (E_END + 19)

used for "selfack"

◆ E_SUBRANGE

#define E_SUBRANGE (E_END + 12)

like array, but it is a subrange

l points to the ValueIdx
r points to another Expr whose l points to Scope r points to the array range

◆ E_TYPE

#define E_TYPE (E_END + 10)

the "l" field will point to an InstType

Function Documentation

◆ act_expr_any_basecase()

Expr * act_expr_any_basecase ( LFILE * l )

◆ act_expr_free_default()

int act_expr_free_default ( Expr * )

◆ act_expr_parse_newtokens()

int act_expr_parse_newtokens ( LFILE * l )

◆ act_parse_expr_intexpr_base()

Expr * act_parse_expr_intexpr_base ( LFILE * l )

◆ act_parse_expr_syn_loop_bool()

Expr * act_parse_expr_syn_loop_bool ( LFILE * l )
