Application Name Paranoia

Situation

Mozilla builds have 2 values to set application name, MOZ_APP_NAME and MOZ_APP_DISPLAYNAME.

• MOZ_APP_NAME is a internal name. typically lower-cased string e.g. "firefox".
• MOZ_APP_DISPLAYNAME is a user-visible name. tipically title-cased string e.g. "Firefox".

Use Cases

	Firefox 2.0	Firefox 3.0	Nightly (1.9)	Debian Iceweasel 2.0
MOZ_APP_NAME	firefox	firefox	firefox	firefox
MOZ_APP_DISPLAYNAME	Firefox	Firefox	Minefield	Iceweasel

Executable Name (unix)	firefox-bin (hardcoded)	firefox-bin (MOZ_APP_NAME)	firefox-bin (MOZ_APP_NAME)	firefox-bin (hardcoded)
UA String	MOZ_APP_DISPLAYNAME	MOZ_APP_DISPLAYNAME	MOZ_APP_DISPLAYNAME	MOZ_APP_DISPLAYNAME

Default Profile (script)	~/.mozilla/firefox (hardcoded)	~/.mozilla/firefox (hardcoded)	~/.mozilla/firefox (hardcoded)	~/.mozilla/firefox (hardcoded)
Default Profile (Directory Service)	~/.mozilla/firefox (nsXREAppData::vender, nsXREAppData::name)	~/.mozilla/firefox (nsXREAppData::vender, nsXREAppData::name)	~/.mozilla/firefox (nsXREAppData::vender, nsXREAppData::name)	~/.mozilla/firefox (nsXREAppData::vender, nsXREAppData::name)

Proposal

Actually, the browser needs 3 names, that is, "firefox", "Minefield" and "Firefox" (See "Nightly" in the above table), respecitively MOZ_APP_NAME, MOZ_APP_DISPLAYNAME and nsXREAppData::name.

MOZ_APP_BRANDNAME

So I'd like to suggest to add a new flag MOZ_APP_BRANDNAME as below.

Proposed Build Configs (Pink is what's new)

	Nightly (proposal)
MOZ_APP_NAME	firefox
MOZ_APP_DISPLAYNAME	Firefox
MOZ_APP_BRANDNAME	Minefield
-
nsXREAppData::name	MOZ_APP_DISPLAYNAME
Executable Name	MOZ_APP_NAME
UA String	MOZ_APP_BRANDNAME
Archive Package Name	MOZ_APP_NAME
Installer Package Name	MOZ_APP_NAME
MacOSX (.app) Name	MOZ_APP_DISPLAYNAME (Minefield -> Firefox)
Windows DDE (installer)	MOZ_APP_DISPLAYNAME
XRemote (-a APPNAME)	nsXREAppData::name + ToLowerCases

More Backwards Compatible

Or, MOZ_APP_TITLENAME, to minimize the changes.

Proposal2, more backwards compatible (Pink is what's new)

	Nightly (proposal2)
MOZ_APP_NAME	firefox
MOZ_APP_DISPLAYNAME	Minefield
MOZ_APP_TITLENAME	Firefox
-
nsXREAppData::name	MOZ_APP_TITLENAME
Executable Name	MOZ_APP_NAME
UA String	MOZ_APP_DISPLAYNAME
Archive Package Name	MOZ_APP_NAME
Installer Package Name	MOZ_APP_NAME
MacOSX (.app) Name	MOZ_APP_TITLENAME (Minefield -> Firefox)
Windows DDE (installer)	MOZ_APP_TITLENAME
XRemote (-a APPNAME)	nsXREAppData::name + ToLowerCases

ToLowerCases Everywhere

Anyway, we need "Firefox" rather than "firefox", because it's easy to create "firefox" from "Firefox", on the other hand, it's difficult to create "Firefox" from "firefox".

Proposal3, ToLowerCases Everywhere (Pink is what's new)

	Nightly (proposal3)
MOZ_APP_NAME	Firefox
MOZ_APP_DISPLAYNAME	Minefield
-
nsXREAppData::name	MOZ_APP_NAME
Executable Name	MOZ_APP_NAME + ToLowerCases
UA String	MOZ_APP_DISPLAYNAME
Archive Package Name	MOZ_APP_NAME + ToLowerCases
Installer Package Name	MOZ_APP_NAME + ToLowerCases
MacOSX (.app) Name	MOZ_APP_NAME (Minefield -> Firefox)
Windows DDE (installer)	MOZ_APP_NAME
XRemote (-a APPNAME)	nsXREAppData::name + ToLowerCases
