GUIDs are used in Mozilla programming for identifying several types of entities, including XPCOM Interfaces (this type of GUIDs is callled IID), components (CID), and legacy add-ons—like extensions and themes—that were created prior to Firefox 1.5. Add-ons can (and should) be identified with IDs of the form extensionname@organization.tld since Firefox 1.5.
Предупреждение: If you just want an ID for your add-on, generating a GUID is almost definitely not what you want to do. Using the extensionname@organization.tld form is approximately one thousand times easier for everyone involved. Don't have a domain name? Do you have a blog on a subdomain? Use that. If all else fails, using extensionname@yourusername.addons.mozilla.org should be fine; no one will care. Remember, these are identifiers, not e-mail addresses, and they're never resolved.
Canonical form
The common form of a GUID is xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx, where each x stands for a hexadecimal digit. There are a number of tools that can be used to generate a GUID in the canonical form.
Note: If you do choose to use an email-style ID for your add-on, you probably don't want it to be a real email address, since it might attract spam.
Online tools
- Генерация GUID онлайн
- UUID (GUID) Generator on the WEB
- Генератор UUID для Mozilla Code (две формы IDL и C++.h)
- Вы можете получить GUID с помощью одного из ботов (например: botbot, firebot) в IRC на канале #firefox с помощью команды
/msg ник_бота"uuid".
Windows
Пользвоатели Windows могут использовать утилиту GuidGen от Microsoft для получения GUID. (Эта утилита является частью MS Visual C++)
Linux
Используйте /usr/bin/uuidgen. Является частью пакета libuuid1 (Debian).
Mac OS X
Используйте. /usr/bin/uuidgen
Perl
- jkeiser's Mozilla tools include a UUID generator with output format of both C++ and IDL style.
- sfink's update-uuids will change the uuid for a given interface and all of its descendants, updating all *.idl files within a directory tree.
nsIUUIDGenerator
A UUID can be generated from privileged Mozilla code using nsIUUIDGenerator. See the linked page for details.
Формат COM/XPCOM
Используя #define для IID и CID в коде Mozilla C++, вы должны использовать следующий формат:
// xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx
#define NS_...ID \
{ 0xXXXXXXXX, 0xXXXX, 0xXXXX, \
{ 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX } }
You can generate code in this format using one of the following tools.
Онлайн утилита
guidgen
guidgen.exe, часть Microsoft Visual Studio, может генерировать UUID в нужном формате.
bash
Можете добавить в файл .bashrc следующий код:
uuidgen-c++()
{
local UUID=$(uuidgen)
echo "// $UUID"
echo "#define NS__IID \\"
echo "{ 0x${UUID:0:8}, 0x${UUID:9:4}, 0x${UUID:14:4}, \\"
echo -n " { 0x${UUID:19:2}, 0x${UUID:21:2}, 0x${UUID:24:2}, "
echo -n "0x${UUID:26:2}, 0x${UUID:28:2}, 0x${UUID:30:2}, "
echo "0x${UUID:32:2}, 0x${UUID:34:2} } }"
}
Perl
#!/usr/bin/perl
$uuid = `uuidgen`;
chomp $uuid;
print $uuid, "\n";
@parts = ($uuid =~ /^(.{8})-(.{4})-(.{4})-(..)(..)-(..)(..)(..)(..)(..)(..)$/);
print "{ 0x$parts[0], 0x$parts[1], 0x$parts[2], \\", "\n", " { ";
for (3 .. 9) {
print "0x$parts[$_], ";
}
print "0x$parts[10] } }", "\n";
