29.1.50; c-ts-mode syntax issues with no brackets |
|

This is specifically for the usage of `c-ts-mode` and is not a problem
in `c-mode`. Sometimes, when you type something like:
else
break
it won't indent the "break" until you type a semicolon. In this below
scenario, it does not indent the break at all, but `c-mode` does, and
switching from `c-mode` to `c-ts-mode` with correct indentation leaves
it fixed, but `c-ts-mode` cannot detect or fix it itself.
You can put it into a `.c` buffer all by itself and see:
```
unsigned
heap_pop(struct heapq * heap)
{
if (heap->sz == 0)
return -1;
unsigned ret_val = heap->vals[0];
heap->vals[0] = heap->vals[heap->len];
heap->len -= 1;
unsigned i = 0;
unsigned lc;
while ((lc = HEAPQ_L_CHILD(i)) < heap->len)
{
unsigned rc = HEAPQ_R_CHILD(i);
/* no right child for our guy, special case */
if (rc == heap->len)
{
if (heap->vals[lc] < heap->vals[i])
SWAP(heap->vals[lc], heap->vals[i]);
break;
}
if (heap->vals[lc] < heap->vals[i])
{
SWAP(heap->vals[lc], heap->vals[i]);
i = lc;
}
else if (heap->vals[rc] < heap->vals[i])
{
SWAP(heap->vals[rc], heap->vals[i]);
i = rc;
}
else
break;
}
}
```
The very last break on the else without brackets around it will not indent.c

The rest of the nodes (if/while/do/for) don't result in parse errors
here, as long as the condition in parentheses is typed out correctly.
I tried some additional clauses looking for "previous sibling",
checking whether it's for_statement, etc, which ends with "expression
statement", and that one is empty... but it a fair amount of code
which will likely miss other edge cases anyway. Or breaks when the
grammar changes.
Yeah, for now we can match for the specific case where there's an else
before a "}". That should reduce the chance of it matching other edge
cases. I'll give it another look on this weekend.
Any progress here?
I pushed a commit that changes the too-board heuristic to only match
"else before closing bracket". Hopefully this won't cause any false
matches.
I think we can close this. Dmitry, WDYT?
LGTM! (And closing.)
Arteen, let us know if you see any problems with the fixes that are now
in the emacs-29 branch.
