"""The shortcut library: trigger -> replacement text, expanded into a prompt at
|
||
generation time. Global, not per-project -- a shortcut ("cyberpunk" -> a long
|
||
style phrase) is reused across every project, not redefined in each one.
|
||
|
||
Storage is one JSON file holding the whole list, not one-per-item: the picker
|
||
browses all of it and export/import round-trips all of it, so there is no
|
||
case where only part of the library is ever read or written.
|
||
|
||
The expansion algorithm (trigger regex, longest-first, seeded multi-choice) and
|
||
`$variable` resolution (recursive, cycle-safe, undefined -> literal) are a
|
||
close port of v4's `templates.py` (`apply_prompt_shortcuts`/`resolve_variables`)
|
||
-- proven logic, not reinvented. Not ported yet: the shortcut revolver's
|
||
no-repeat cycling (a stateful commit-vs-preview split).

another -- cycle-safe (a name reappearing in its own expansion chain is

left literal rather than recursed into), and undefined names are left as

literal `$name`: an unset variable is a typo to notice and fix, not a

Memoized per (name, stack): a value referencing the SAME variable more

than once (`v0 = "$v1 $v1"`) is not a cycle -- `name in stack` never

trips -- so without this a chain of only two dozen such variables costs

2**24 evaluations of the last one and tens of megabytes of output before

_VARIABLE_MAX_DEPTH ever gets the chance to matter (that cap bounds

depth, not the branching this shape produces). The cache key includes

`stack`, not just `name`, because the SAME variable can legitimately

resolve differently depending on which cycle it is being asked from

(A="$B", B="$A": resolving from A ends in literal "$A", from B in

literal "$B") -- collapsing by name alone would answer one of those with

the other's result. Past memoization, `_VARIABLE_MAX_OUTPUT` bounds the

total characters produced -- once hit, remaining tokens are left literal
