<remarks>
|
14
|
This looks very much like an ANTLReaderStream or an ANTLRInputStream
|
15
|
but, it is a special case. Since we know the exact size of the file to
|
16
|
load, we can avoid lots of data copying and buffer resizing.

<remarks>
|
453
|
No buffering is required to do this unless you know your stream
|
454
|
will use seek to move backwards such as when backtracking.
|
455
|
This is different from rewind in its multi-directional requirement
|
456
|
and in that its argument is strictly an input cursor (index).
|
457
|
For char streams, seeking forward must update the stream state such
|
458
|
as line number. For seeking backwards, you will be presumably
|
459
|
backtracking using the
|
460
|
<see cref="M:Antlr.Runtime.IIntStream.Mark" />/<see cref="M:Antlr.Runtime.IIntStream.Rewind(System.Int32)" />
|
461
|
mechanism that restores state and so this method does not need to
|
462
|
update state when seeking backwards.
|
463
|
Currently, this method is only used for efficient backtracking using
|
464
|
memoization, but in the future it may be used for incremental parsing.
|
465
|
The index is 0..n-1. A seek to position i means that LA(1) will return
|
466
|
the ith symbol. So, seeking to 0 means LA(1) will return the first
|
467
|
element in the stream.

|
<remarks>
|
537
|
To avoid English-only error messages and to generally make things
|
538
|
as flexible as possible, these exceptions are not created with strings,
|
539
|
but rather the information necessary to generate an error. Then
|
540
|
the various reporting methods in Parser and Lexer can be overridden
|
541
|
to generate a localized error message. For example, MismatchedToken
|
542
|
exceptions are built with the expected token type.
|
543
|
So, don't expect getMessage() to return anything.
|
544
|
You can access the stack trace, which means that you can compute the
|
545
|
complete trace of rules from the start symbol. This gives you considerable
|
546
|
context information with which to generate useful error messages.
|
547
|
ANTLR generates code that throws exceptions upon recognition error and
|
548
|
also generates code to catch these exceptions in each rule. If you
|
549
|
want to quit upon first error, you can turn off the automatic error
|
550
|
handling mechanism using rulecatch action, but you still need to
|
551
|
override methods mismatch and recoverFromMismatchSet.
|
552
|
In general, the recognition exceptions can track where in a grammar a
|
553
|
problem occurred and/or what was the expected input. While the parser
|
554
|
knows its state (such as current input symbol and line info) that
|
555
|
state can change before the exception is reported so current token index
|
556
|
is computed and stored at exception time. From this info, you can
|
557
|
perhaps print an entire line of input not just a single token, for example.
|
558
|
Better to just say the recognizer had a problem and then let the parser
|
559
|
figure out a fancy report.

A TreeAdaptor that works with any Tree implementation. It provides

1050
|
really just factory methods; all the work is done by BaseTreeAdaptor.
|
1051
|
If you would like to have different tokens created than ClassicToken
|
1052
|
objects, you need to override this and then set the parser tree adaptor to
|
1053
|
use your subclass.
|
1054
|
To get your parser to build nodes of a different type, override
|
1055
|
Create(Token), ErrorNode(), and to be safe, YourTreeClass.DupNode().
|
1056
|
DupNode() is called to duplicate nodes during rewrite operations.

For example, there is probably no input symbol associated with imaginary

This is a variant of createToken where the new token is derived from

an actual real input token. Typically this is for converting '{'

This node stream sucks all nodes out of the tree specified in the

using an array of Object pointers. The stream necessarily includes

pointers to DOWN and UP and EOF nodes.

1120

This stream knows how to mark/release for backtracking.

This stream is most suitable for tree interpreters that need to
|
1122
|
jump around a lot or for tree parsers requiring speed (at cost of memory).

There is some duplicated functionality here with UnBufferedTreeNodeStream

What does a tree look like? ANTLR has a number of support classes
|
1254
|
such as CommonTreeNodeStream that work on these kinds of trees. You

1255
|
don't have to make your trees implement this interface, but if you do,
|
1256
|
you'll be able to use more support code.
|
1257
|
NOTE: When constructing trees, ANTLR can build any kind of tree; it can
|
1258
|
even use Token objects as trees if you add a child list to your tokens.
|
1259
|
This is a tree node without any payload; just navigation and factory stuff.

To watch a parser move through the grammar, the parser needs to

inform the debugger what line/charPos it is passing in the grammar.

For now, this does not know how to switch from one grammar to the

other and back for island grammars etc...

A recognition exception occurred such as NoViableAltException. I made
|
1878
|
this a generic event so that I can alter the exception hierachy later
|
1879
|
without having to alter all the debug objects.
|
1880
|
Upon error, the stack of enter rule/subrule must be properly unwound.
|
1881
|
If no viable alt occurs it is within an enter/exit decision, which
|
1882
|
also must be rewound. Even the rewind for each mark must be unwount.
|
1883
|
In the C# target this is pretty easy using try/finally, if a bit
|
1884
|
ugly in the generated code. The rewind is generated in DFA.Predict()
|
1885
|
actually so no code needs to be generated for that. For languages
|
1886
|
w/o this "finally" feature (C++?), the target implementor will have
|
1887
|
to build an event stack or something.
|
1888
|
Across a socket for remote debugging, only the RecognitionException
|
1889
|
data fields are transmitted. The token object or whatever that
|
1890
|
caused the problem was the last object referenced by LT. The
|
1891
|
immediately preceding LT event should hold the unexpected Token or
|
1892
|
char.
|
1893
|
Here is a sample event trace for grammar:

b : C ({;}A|B) // {;} is there to prevent A|B becoming a set

A nil was created (even nil nodes have a unique ID...

they are not "null" per se). As of 4/28/2006, this
|
1994
|
seems to be uniquely triggered when starting a new subtree

1995

such as when entering a subrule in automatic mode and when

1996

building a tree in rewrite mode.

2322
|
navigate trees using methods. This class helps you do it with string

2323
|
patterns like "(A B C)". You can create a tree from that pattern or

match subtrees against it.

No new nodes should be created in tree during the walk. A small buffer

2707

the lookahead mechanism is fairly complicated.

For tree rewriting during tree parsing, this must also be able

That part is not yet implemented. Will permit a rule to return

This method sets errorRecovery to indicate the parser is recovering

3082
|
not parsing. Once in recovery mode, no errors are generated.
|
3083
|
To get out of recovery mode, the parser must successfully Match
|
3084
|
a token (after a resync). So it will go:
|
3085
|
1. error occurs
|
3086
|
2. enter recovery mode, report error
|
3087
|
3. consume until token found in resynch set
|
3088
|
4. try to resume parsing
|
3089
|
5. next Match() will reset errorRecovery mode
|

If you override, make sure to update syntaxErrors if you care about that.

What error message should be generated for the various exception types?
|
3096

Not very object-oriented code, but I like having all error message generation
|
3097
|
within one method rather than spread among all of the exception classes. This
|
3098
|
also makes it much easier for the exception handling because the exception
|
3099
|
classes do not have to have pointers back to this object to access utility

3100

routines and so on. Also, changing the message for an exception type would be

3101

difficult because you would have to subclassing exception, but then somehow get
|
3102
|
ANTLR to make those kinds of exception objects instead of the default.
|
3103

This looks weird, but trust me--it makes the most sense in terms of flexibility.

to use t.ToString() (which, for CommonToken, dumps everything about

EXTRA TOKEN
|
3151

LA(1) is not what we are looking for. If LA(2) has the right token,

3152

however, then assume LA(1) is some extra spurious token. Delete it

3153

|
3155
|
MISSING TOKEN
|
3156
|
If current token is consistent with what could come after

3157

ttype then it is ok to "insert" the missing token, else throw
|
3158
|
exception For example, Input "i=(3;" is clearly missing the
|
3159

')'. When the parser returns from the nested call to expr, it
|
3160
|
will have call chain:
|
3161
|
stat -> expr -> atom

3162
|
and it will be trying to Match the ')' at this point in the

derivation:

|
3165

^

Match() will see that ';' doesn't Match ')' and report a

3167

mismatched token error. To Recover, it sees that LA(1)==';'
|
3168
|
is in the set of tokens that can follow the ')' token

reference given a specific call chain. You get the set of

viable tokens that can possibly come next (lookahead depth 1)

definition of plain FOLLOW for rule r:
|
3259
|
FOLLOW(r)={x | S=>*alpha r beta in G and x in FIRST(beta)}
|
3260
|
where x in T* and alpha, beta in V*; T is set of terminals and
|
3261
|
V is the set of terminals and nonterminals. In other words,
|
3262
|
FOLLOW(r) is the set of all tokens that can possibly follow
|
3263
|
references to r in *any* sentential form (context). At
|
3264
|
runtime, however, we know precisely which context applies as
|
3265
|
we have the call chain. We may compute the exact (rather
|
3266
|
than covering superset) set of following tokens.
|
3267
|
For example, consider grammar:
|
3268
|
stat : ID '=' expr ';' // FOLLOW(stat)=={EOF}
|
3269
|
| "return" expr '.'
|
3270
|
;
|
3271
|
expr : atom ('+' atom)* ; // FOLLOW(expr)=={';','.',')'}
|
3272
|
atom : INT // FOLLOW(atom)=={'+',')',';','.'}
|
3273
|
| '(' expr ')'
|
3274
|
;
|
3275
|
The FOLLOW sets are all inclusive whereas context-sensitive
|
3276
|
FOLLOW sets are precisely what could follow a rule reference.
|
3277
|
For input input "i=(3);", here is the derivation:
|
3278
|
stat => ID '=' expr ';'
|
3279
|
=> ID '=' atom ('+' atom)* ';'
|
3280
|
=> ID '=' '(' expr ')' ('+' atom)* ';'
|
3281
|
=> ID '=' '(' atom ')' ('+' atom)* ';'
|
3282
|
=> ID '=' '(' INT ')' ('+' atom)* ';'
|
3283
|
=> ID '=' '(' INT ')' ';'

At the "3" token, you'd have a call chain of

3285

stat -> expr -> atom -> expr -> atom
|
3286

What can follow that specific nested ref to atom? Exactly ')'

as you can see by looking at the derivation of this specific

input. Contrast this with the FOLLOW(atom)={'+',')',';','.'}.

You want the exact viable token set when recovering from a

3290

token mismatch. Upon token mismatch, if LA(1) is member of

3291

the viable next token set, then you know there is most likely

3292

a missing token in the input stream. "Insert" one by just not

Match needs to return the current input symbol, which gets put

<remarks>
|
3312
|
The recognizer attempts to recover from single missing
|
3313
|
symbols. But, actions might refer to that missing symbol.
|
3314
|
For example, x=ID {f($x);}. The action clearly assumes
|
3315
|
that there has been an identifier matched previously and that
|
3316
|
$x points at that token. If that token is missing, but
|
3317
|
the next token in the stream is what we want we assume that
|
3318
|
this token is missing and we keep going. Because we
|
3319
|
have to return some token to replace the missing token,
|
3320
|
we have to conjure one up. This method gives the user control
|
3321
|
over the tokens returned for missing tokens. Mostly,
|
3322
|
you will want to create something special for identifier
|
3323
|
tokens. For literals such as '{' and ',', the default
|
3324
|
action in the parser or tree parser works. It simply creates
|
3325
|
a CommonToken of the appropriate type. The text will be the token.
|
3326
|
If you change what tokens must be created by the lexer,
|
3327
|
override this method to create the appropriate tokens.

a token, so do the easy thing and just kill a character and hope

<remarks>
|
3688
|
You can insert stuff, Replace, and delete chunks. Note that the
|
3689
|
operations are done lazily--only if you convert the buffer to a
|
3690
|
String. This is very efficient because you are not moving data around
|
3691
|
all the time. As the buffer of tokens is converted to strings, the
|
3692
|
ToString() method(s) check to see if there is an operation at the
|
3693
|
current index. If so, the operation is done and then normal String
|
3694
|
rendering continues on the buffer. This is like having multiple Turing
|
3695
|
machine instruction streams (programs) operating on a single input tape. :)
|
3696
|
Since the operations are done lazily at ToString-time, operations do not
|
3697
|
screw up the token index values. That is, an insert operation at token
|
3698
|
index i does not change the index values for tokens i+1..n-1.
|
3699
|
Because operations never actually alter the buffer, you may always get
|
3700
|
the original token stream back without undoing anything. Since
|
3701
|
the instructions are queued up, you can easily simulate transactions and
|
3702
|
roll back any changes if there is an error just by removing instructions.
|
3703
|
For example,
|
3704
|
CharStream input = new ANTLRFileStream("input");
|
3705
|
TLexer lex = new TLexer(input);
|
3706
|
TokenRewriteStream tokens = new TokenRewriteStream(lex);
|
3707
|
T parser = new T(tokens);
|
3708
|
parser.startRule();
|
3709
|
Then in the rules, you can execute
|
3710
|
IToken t,u;
|
3711
|
...
|
3712
|
input.InsertAfter(t, "text to put after t");}
|
3713
|
input.InsertAfter(u, "text after u");}
|
3714
|
System.out.println(tokens.ToString());
|
3715
|
Actually, you have to cast the 'input' to a TokenRewriteStream. :(
|
3716
|
You can also have multiple "instruction streams" and get multiple
|
3717
|
rewrites from a single pass over the input. Just name the instruction
|
3718
|
streams and use that name again when printing the buffer. This could be
|
3719
|
useful for generating a C file and also its header file--all from the
|
3720
|
same buffer:
|
3721
|
tokens.InsertAfter("pass1", t, "text to put after t");}
|
3722
|
tokens.InsertAfter("pass2", u, "text after u");}
|
3723
|
System.out.println(tokens.ToString("pass1"));
|
3724
|
System.out.println(tokens.ToString("pass2"));
|
3725
|
If you don't use named rewrite streams, a "default" stream is used as
|
3726
|
the first example shows.

<remarks>We need to combine operations and report invalid operations (like

3766
|
overlapping replaces that are not completed nested). Inserts to
|
3767
|
same index need to be combined etc... Here are the cases:
|
3768
|
I.i.u I.j.v leave alone, nonoverlapping
|
3769
|
I.i.u I.i.v combine: Iivu
|
3770
|
R.i-j.u R.x-y.v | i-j in x-y delete first R
|
3771
|
R.i-j.u R.i-j.v delete first R
|
3772
|
R.i-j.u R.x-y.v | x-y in i-j ERROR
|
3773
|
R.i-j.u R.x-y.v | boundaries overlap ERROR
|
3774
|
I.i.u R.x-y.v | i in x-y delete I
|
3775
|
I.i.u R.x-y.v | i not in x-y leave alone, nonoverlapping
|
3776
|
R.x-y.v I.i.u | i in x-y ERROR
|
3777
|
R.x-y.v I.x.u R.x-y.uv (combine, delete I)
|
3778
|
R.x-y.v I.i.u | i not in x-y leave alone, nonoverlapping
|
3779
|
I.i.u = insert u before op @ index i
|
3780
|
R.x-y.u = replace x-y indexed tokens with u
|
3781
|
First we need to examine replaces. For any replace op:
|
3782
|
1. wipe out any insertions before op within that range.
|
3783
|
2. Drop any replace op before that is contained completely within
|
3784
|
that range.
|
3785
|
3. Throw exception upon boundary overlap with any previous replace.
|
3786
|
Then we can deal with inserts:
|
3787
|
1. for any inserts to same index, combine even if not adjacent.
|
3788
|
2. for any prior replace with same left boundary, combine this
|
3789
|
insert with replace and delete this replace.
|
3790
|
3. throw exception if index in same range as previous replace
|
3791
|
Don't actually delete; make op null in list. Easier to walk list.
|
3792
|
Later we can throw as we add to index -> op map.
|
3793
|
Note that I.2 R.2-2 will wipe out I.2 even though, technically, the
|
3794
|
inserted stuff would be before the replace range. But, if you
|
3795
|
add tokens in front of a method body '{' and then delete the method
|
3796
|
body, I think the stuff before the '{' you added should disappear too.
