JSON schema conversion: ⚡️ faster repetitions, min/maxLength for strings, cap number length (#6555)
* json: rename python schema converter to make import easier
* server: skip null json_schema / grammar fields
* json: deps management for primitive rules (+ allow null values)
* json: optimize repetitions for minItems/maxItems and regexps: `a{,3}` goes from `"a"? "a"? "a"?` (explosive combos) to `(a (a (a)?)?)?`
* grammars: add troubleshooting section to readme
* json: cap length of numbers to 15 digits before/after decimal point
(avoids infinite gen, e.g. "one third" -> `0.333333333333...`)
* json: unify all repetition code (w/ or w/o sep)
* json: support string minLength/maxLength
* server+json: update server/README w/ result_format
* nits
* json: fix type error w/ python 3.8
* json: fix server/README (json_schema in /completion vs. result_format in /v1/chat/completions)
* json: simplify DOT `{"type": "string", "pattern": "^.$"}`
* json: remove recursion in opt_repetitions (avoids Python stack overflow)
* json: rm dead code
* json: rm useless assert & ggml.h import

## Troubleshooting
|
||||
|
||||
Grammars currently have performance gotchas (see https://github.com/ggerganov/llama.cpp/issues/4218).
|
||||
|
||||
### Efficient optional repetitions
|
||||
|
||||
A common pattern is to allow repetitions of a pattern `x` up to N times.
|
||||
|
||||
While semantically correct, the syntax `x? x? x?.... x?` (with N repetitions) will result in extremely slow inference. Instead, you can write `(x (x (x ... (x)?...)?)?)?` (w/ N-deep nesting)
