I was trying to use a library (fswatch) for watching the file
system but I immediately ran into an error using it so I decided
to write my own.
Funny thing: I ran into the same error.
It seems that there's some problem with files with a name like
`#tests.txt#` (which emacs likes to create).
My code is really basic, when the directory modified timestamp
changes, I list the directory entries with `dirEntries` and then
call `dirEntry.getTimes()` on it.
```d
import std.file;
import std.stdio;
import std.datetime.systime;
import std.stdio: writefln;
void main(string[] args) {
assert(args.length == 2);
foreach (DirEntry entry; args[1].dirEntries(SpanMode.shallow)) {
SysTime st, ac;
entry.getTimes(ac, st);
writefln("entry %s changed at %s", entry.name, st);
}
}
```
Create a directory like this:
```
hello
├── #hi.txt#
└── hi.txt
```
Running this, I get:
```
▶ ldc2 -L-ld_classic -run main.d hello
entry hello/hi.txt changed at 2023-Dec-24 14:36:01.1020473
entry hello/#hi.txt# changed at 2023-Dec-24 14:40:26.7945088
std.file.FileException@/Users/renato/dlang/ldc-1.35.0/bin/../import/std/file.d(1282):

```
As you can see, the name of the file in the exception seems
wrong. It should be `#hi.txt#`, but it tries to access `.#hi.txt`.
I actually reproduced this in both Mac and Linux... on Linux,
though, it shows a "funny" directory listing which perhaps
explains something:
```
l
rwxrwxrwx 1 renato renato 31 Dec 24 15:13 .#hi.txt ->
renato@renato.902129:1701726658
```
The `.#hi.txt ->` (seems like a link?) is shown in red on the
terminal... I don't understand what exactly this is (links are
not shown red).
Can anyone help me understand this? Should I ignore file names
starting with `.#` perhas?
