I'm sorry, could you be more specific?

example: Watch("~/tmp/tmp.txt")
i modify tmp.txt,
tip:

2013/03/14 15:41:23 event: "/home/yufeng/tmp/t.txt": RENAME
2013/03/14 15:41:23 event: "/home/yufeng/tmp/t.txt": MODIFY
2013/03/14 15:41:23 event: "/home/yufeng/tmp/t.txt": DELETE

Modified again,no new event.
i want watch file event,not watch dir.

That's because it is watching a file, and not a file path location. In your
example, once "/home/yufeng/tmp/t.txt" is deleted you lose your watch.

no delete it .i'am modify it

[howeyc]

Is it possible you are using a file editor program to do the modify? I've seen some programs delete and recreate files when doing modifications. I don't know why, but they do.

Ya I've seen Xcode do this, not sure why either

Probably an attempt at atomic saves, so they write the file contents to a temporary file, then delete the original file and lastly rename the temp file to the original file's name.

If someone stumbles on this via Google: vim does the same, Create Temp, Delete Original (thus losing watch), Rename Temp (which isn't being watched now)

yah, it would seem that pretty much every editor has an "atomic save" like this, presumably to avoid the terrible thing that happens when a file is half written and something crashes.
