我有这个图:
digraph G {
1 [label="car"];
2 [label="x"];
3 [label="car"];
4 [label="y"];
5 [label="cdr"];
6 [label="cdr"];
7 [label="cons"];
8 [label="x1"];
9 [label="x2"];
10 [label="cons"];
11 [label="y1"];
12 [label="y2"];
13 [label="f"];
14 [label="f"];
15 [label="car"];
16 [label="cdr"];
17 [label="car"];
18 [label="cdr"];
1 -> 2;
3 -> 4;
5 -> 2;
6 -> 4;
7 -> 8;
7 -> 9;
10 -> 11;
10 -> 12;
13 -> 2;
14 -> 4;
15 -> 7;
16 -> 7;
17 -> 10;
18 …我知道如何使用SKIP声明跳过这些注释,但我需要做的就是获取C源并输出相同的源而不带注释.
所以我声明了一个令牌<GENERIC_TEXT:(〜[])+>,它被复制到输出中,并且不会跳过注释.我怀疑这个令牌为自己获取所有输入.
有谁可以帮助我吗？
谢谢
