Bad error recovery from (incorrect) C preprocessor error
arbrauns opened this issue · comments
The following file, which is parsed incorrectly by tree-sitter-c due to tree-sitter/tree-sitter-c#108:
static void foo(void) {
#if FOREVER
while (1) {
#endif
foo();
#if FOREVER
}
#endif
}
static void bar(void) {
if (1) {
var = (func(a, a.b) + a.b.c);
} else {
var = func(a, a.b) + a.b + a.b.c + a.b.c + a.b.c;
}
}Produces these --dump-ts/--dump-syntax outputs:

The single error node smooshes everything into a single atom, breaking diff.
Simplifying pretty much anything in the example produces a much more usable output without an error node, e.g. removing one of the .c in L15:
static void foo(void) {
#if FOREVER
while (1) {
#endif
foo();
#if FOREVER
}
#endif
}
static void bar(void) {
if (1) {
var = (func(a, a.b) + a.b.c);
} else {
var = func(a, a.b) + a.b + a.b.c + a.b.c + a.b;
}
