List the extensions installed in Safari for Mac OS X, and state whether each one is enabled

Question

I'd like a list, from which text can be copied.

(Not a screenshot of preferences.)

This information does not appear in any of the following:

• Safari
• System Profiler in Snow Leopard
• System Information in Lion.

I wondered whether there exists an extension to list other extensions, but when I searched I could not find anything suitable.

If not a command or an extension, maybe there's an app, but again: I could not find anything suitable.

(I could instead have posted this opening question to Super User, where a command piping guru might step up, but I prefer Ask Different for the likelihood of someone knowing an extension or app.)

Background

With the extensions master switch off, the simple presence of installed extensions may cause some versions of Safari to take longer than expected to launch.

For that reason and others, it's sometimes necessary to have a comprehensive list of installed extensions, including those that are disabled.

Answer 1

It's primarily a matter of parsing the output of defaults read ~/Library/Safari/Extensions/extensions and formatting it in a user-friendly way. The result actually answers both of your questions:

defaults read ~/Library/Safari/Extensions/extensions | awk '
/Bundle Directory/ {
    split($0, t, /\"/);
    sub(".safariextension", "", t[4]);
    sub("-1", "", t[4]);
    bundle=t[4]
    e="disabled"
}
/Enabled/ {
    e="enabled";
}
/Hidden Bars/ {
    print bundle, "...", e
}' | sort --ignore-case

Creating a shell script out of it is left as an exercise to the reader.

Please note that this will most probably stop to work if Apple decides to change the format of ~/Library/Safari/Extensions/extensions

Answer 2

For posterity, another simple starting point that originated from what was once a different question:

List of enabled extensions, unsorted

defaults read ~/Library/Safari/Extensions/extensions | grep -B 1 "Enabled = 1"

The result is quick, but dirty:

• for each item found there are three lines, one should suffice
• in the one line of interest, the leading "Bundle Directory Name" = " and trailing "; are unnecessary
• some of the bundle directory names include -1 — this, too, is unnecessary.

For Safari in pre-release build 16A319 of macOS Sierra (Mac OS X 10.12)

defaults read ~/Library/Safari/Extensions/extensions | grep -B 5 "Enabled = 1"

Answer 3

touch ~/Library/Safari/Extensions/extensions
defaults read ~/Library/Safari/Extensions/extensions | awk '
/Bundle Directory/ {
    split($0, t, /\"/);
    sub(".safariextension", "", t[4]);
    sub("-1", "", t[4]);
    bundle=t[4]
    e=""
}
/Enabled/ {
    e="... enabled";
}
/Hidden Bars/ {
    print bundle, e
}' | sort --ignore-case

This variation on the accepted answer includes extensions that are disabled without labelling them as such. A personal preference — the resulting white space helps me to see, at a glance, those that are enabled.

Answer 4

A simple starting point, posted at the same time as the opening question:

Simple list of installed extensions, sorted alphabetically

defaults read ~/Library/Safari/Extensions/extensions | grep "Bundle Directory Name" | sort --ignore-case

The result is quick, but dirty:

• in the one line of interest, the leading "Bundle Directory Name" = " and trailing "; are unnecessary
• some of the bundle directory names include -1 — this, too, is unnecessary.
