GitRepo.walkMergeHead

Call the callback function for each entry in the MERGE_HEAD file in this repository.

The callback type must be either MergeHeadFunction or MergeHeadDelegate.

This function will return when either all entries are exhausted or when the callback returns ContinueWalk.no.

void walkMergeHead(MergeHeadFunction callback)
void walkMergeHead(MergeHeadDelegate callback)
struct GitRepo
void
walkMergeHead
(
scope MergeHeadDelegate callback
)
auto walkMergeHead()

Examples

Walk the MERGE_HEAD file with a function.

auto repo = initRepo(_userRepo, OpenBare.yes);
scope(exit) rmdirRecurse(_userRepo);

string[] mergeHeadItems = [
    "e496660174425e3147a0593ced2954f3ddbf65ca\n",
    "e496660174425e3147a0593ced2954f3ddbf65ca\n"
];

std.file.write(buildPath(repo.path, "MERGE_HEAD"), mergeHeadItems.join());

static ContinueWalk walkFunc(GitOid oid)
{
    static int count;
    count++;

    assert(count != 2);  // we're stopping after the first iteration

    assert(oid == GitOid("e496660174425e3147a0593ced2954f3ddbf65ca"));

    return ContinueWalk.no;
}

repo.walkMergeHead(&walkFunc);

Walk the MERGE_HEAD file with a delegate.

auto repo = initRepo(_userRepo, OpenBare.yes);
scope(exit) rmdirRecurse(_userRepo);

string[] mergeHeadItems = [
    "e496660174425e3147a0593ced2954f3ddbf65ca\n",
    "e496660174425e3147a0593ced2954f3ddbf65ca\n"
];

std.file.write(buildPath(repo.path, "MERGE_HEAD"), mergeHeadItems.join());

struct S
{
    size_t count;

    // delegate walker
    ContinueWalk walker(GitOid oid)
    {
        string line = mergeHeadItems[count++];
        string commitHex = line.split[0];
        assert(oid == GitOid(commitHex));

        return ContinueWalk.yes;
    }

    ~this()
    {
        assert(count == 2);  // verify we've walked through all the items
    }
}

S s;
repo.walkMergeHead(&s.walker);
