5.1.1 Convert selection to variable

The command versor-languide-convert-selection-to-variable takes the current selection as an expression, sets up a variable (at the nearest scoping point) initialised to that expression, and replaces the original expression with that variable.

The variable name is left on the kill ring, ready for you to re-use, as the likely use of this command is that you want to use a value in two places, where it originally occurred once, in-line.

In the normal Versor key bindings, this command is bound to C-insert =.

If languide-make-variables-interactively is non-nil, the users chooses the scope using an interface similar to isearch; otherwise, it uses the following rules:

• With no prefix arg, it takes the nearest binding scope.
• With a positive numeric prefix arg, it goes out that number of binding scopes.
• With a negative prefix arg, it lets the user choose interactively, just as though languide-make-variables-interactively were non-nil.
• With a non-numeric prefix arg, this tries to find the widest scope in which all the necessary variables are bound, thus making the value re-usable over as much code as possible. However, it does not (in the current version of Versor/Languide) take note of assignments to those variables, so this may not be the one you want. Future versions of the software should handle this correctly.
