$InactivateExclusions

$InactivateExclusions

is a variable whose value is used to determine which heads Inactivate should ignore.

Examples

open all close all

Basic Examples  (2)

Force all symbols to be inactivated:

Wolfram Language code: Needs["Developer`"]; Block[{$InactivateExclusions = {}}, Inactivate[{g[1 + 1], h[2x]}]]

Normally List would be ignored:

Wolfram Language code: Inactivate[{g[1 + 1], h[2x]}]

Ignore List but not its contents:

Wolfram Language code: Needs["Developer`"] Block[{$InactivateExclusions = {{List, "Symbol"}}}, Inactivate[{g[1 + 1], h[2x]}]]

Ignore List and its contents:

Wolfram Language code: Block[{$InactivateExclusions = {{List, "Expression"}}}, Inactivate[{g[1 + 1], h[2x]}]]

Scope  (2)

Ignore g and its contents, and ignore h but not its contents:

Wolfram Language code: Needs["Developer`"] Block[{$InactivateExclusions = {{g, "Expression"}, {h, "Symbol"}}}, Inactivate[{g[1 + 1], h[2x]}]]

Ignore these functions in addition to the normal defaults:

Wolfram Language code: Needs["Developer`"] Block[{$InactivateExclusions = Join[$InactivateExclusions, {{g, "Expression"}, {h, "Symbol"}}]}, Inactivate[{g[1 + 1], h[2x]}]]

Ignore no symbols:

Wolfram Language code: Needs["Developer`"] $InactivateExclusions = {}
Wolfram Language code: Inactivate[{a, b}]

Restore $InactivateExclusions to its default value:

Wolfram Language code: $InactivateExclusions=.

Now List is ignored:

Wolfram Language code: Inactivate[{a, b}]
