This was required when we linked each framework as its own thing, which we do not do anymore, and if we do go back to this system, we can simply have symbols public by default.
Previously we used the system’s temporary directory and removed the script after use.
This is because macOS 10.15 will “call home” (notarization?) when executing a new script (that it has not seen before), so with an unstable network connection, running commands could take several seconds.
We previously avoided this link dependency because it would cause a cyclic dependency. The build system does however not error on cycles in the dependency graph as they are all statically linked together (rather than dynamically linking with each other).
Only cycles between root targets would cause a problem.
Versions of the OS X 10.11 SDK prior to 10.11.4 require this to
be done explicitly. This fixes the build on OS X 10.10 when
using the OS X 10.11 SDK from Xcode 7.2.1 and earlier.
This is done by setting the ‘disableJavaScriptAPI’ key to ‘true’ in the tmCommand file.
The rationale behind this is that a command like “HTML → Show Preview” is using the HTML output view with user data which should not have access to the special TextMate JavaScript object, for example a user may have a `<script>` tag that loads JavaScript from a CDN, and such script would effectively have shell access to the user’s machine.
These are both set to nil when the app loses focus, and even in an NSApplicationDidBecomeActiveNotification these are still nil.
This means any command running while the app was inactive or as part of a “did become active” notification, would not find the proper objects to setup environment etc.
