append_str [line 2533]

void append_str(
string
$zText, int
$n)

Append text to a dynamically allocated string. If zText is 0 then reset the string to be empty again. Always return the complete text of the string (which is overwritten with each call).

n bytes of zText are stored. If n==0 then all of zText is stored.

If n==-1, then the previous character is overwritten.

Parameters:

string	`$zText`	—
int	`$n`	—

[ Top ]

axset_compare [line 2708]

void axset_compare(

$a, 
$b)

Compare to axset structures for sorting purposes

Parameters:

	`$a`	—
	`$b`	—

[ Top ]

CompressTables [line 1644]

void CompressTables(
)

Reduce the size of the action tables, if possible, by making use of defaults.

In this version, we take the most frequent REDUCE action and make it the default.

[ Top ]

compute_action [line 1744]

void compute_action(
LemonAction
$ap)

Given an action, compute the integer value for that action which is to be put in the action table of the generated machine.

Return negative if no action should be generated.

Parameters:

LemonAction $ap —

[ Top ]

emit_code [line 2507]

void emit_code(

$out, LemonRule
$rp, 
&$lineno)

Generate code which executes when the rule "rp" is reduced. Write the code to "out". Make sure lineno stays up-to-date.

Parameters:

	`$out`	—
LemonRule	`$rp`	—
	`&$lineno`	—

[ Top ]

emit_destructor_code [line 2659]

void emit_destructor_code(

$out, LemonSymbol
$sp, 
&$lineno)

The following routine emits code for the destructor for the

symbol sp

Parameters:

	`$out`	—
LemonSymbol	`$sp`	—
	`&$lineno`	—

[ Top ]

FindActions [line 1483]

void FindActions(
)

Compute the reduce actions, and resolve conflicts.

[ Top ]

FindFirstSets [line 1206]

void FindFirstSets(
)

[ Top ]

FindFollowSets [line 1908]

void FindFollowSets(
)

Compute all followsets.

A followset is the set of all symbols which can come immediately after a configuration.

[ Top ]

FindLinks [line 1458]

void FindLinks(
)

Construct the propagation links

[ Top ]

FindRulePrecedences [line 1180]

void FindRulePrecedences(
)

[ Top ]

FindStates [line 1278]

void FindStates(
)

Compute all LR(0) states for the grammar. Links are added to between some states so that the LR(1) follow sets can be computed later.

[ Top ]

ReportOutput [line 1769]

void ReportOutput(
)

Generate the "y.output" log file

[ Top ]

ReportTable [line 1941]

void ReportTable(
int
$mhflag)

Generate C source code for the parser

Parameters:

int $mhflag — Output in makeheaders format if true

[ Top ]

resolve_conflict [line 1574]

void resolve_conflict(
LemonAction
$apx, LemonAction
$apy, LemonSymbol|null
$errsym)

Resolve a conflict between the two given actions. If the conflict can't be resolve, return non-zero.

NO LONGER TRUE: To resolve a conflict, first look to see if either action is on an error rule. In that case, take the action which is not associated with the error rule. If neither or both actions are associated with an error rule, then try to use precedence to resolve the conflict.

If either action is a SHIFT, then it must be apx. This function won't work if apx->type==REDUCE and apy->type==SHIFT.

Parameters:

LemonAction	`$apx`	—
LemonAction	`$apy`	—
LemonSymbol\|null	`$errsym`	—	The error symbol (if defined. NULL otherwise)

[ Top ]

ResortStates [line 1708]

void ResortStates(
)

Renumber and resort states so that states with fewer choices occur at the end. Except, keep state 0 as the first state.

[ Top ]

translate_code [line 2565]

void translate_code(
LemonRule
$rp)

zCode is a string that is the action associated with a rule. Expand the symbols in this string so that the refer to elements of the parser stack.

Parameters:

LemonRule $rp —
