get_move
Get one move's program and readable text
Returns one ready-made Jabbertoon move: its block program as JSON (the language Jabbertoon's animation engine plays, described at https://jabbertoon.com/docs/language/), the same program as readable text, its length, its page and links that open it. Name the move by its id (c4c:beh:wave_hello), its short name (wave_hello) or the last part of its page URL. To write your own move, start from one: change the program, check it with validate, then make a link with share_link.

list_characters
List Jabbertoon's ready-made cartoon characters
Lists the six ready-made cartoon characters (person, kid, dog, cat, bird, monster): how many legs each has, the views it can be drawn in (front, side, back), the colour slots and options a cast entry's look can set, its page on jabbertoon.com, and links that open it in the cartoon studio or the character creator. A cartoon's cast is an object keyed by the ids its blocks name in who, and each entry draws a character by look.template, for example {"dog": {"name": "Biscuit", "look": {"template": "dog", "style": "outlined"}}}; list_looks gives the styles. The answer also has cartoon_example, a whole talking cartoon to copy and change.

list_looks
List Jabbertoon's art styles (looks) and body shapes
Lists the six art styles (looks) a Jabbertoon character can be drawn in (flat, outlined, soft, storybook, bold, crayon), what each looks like, its page on jabbertoon.com and a studio link that opens the studio in that look; and the three body shapes (classic, big head, tall). A cast entry sets them as look.style and look.shape, for example {"look": {"template": "cat", "style": "crayon", "shape": "bighead"}}.

list_moves
List Jabbertoon's ready-made cartoon moves
Lists the ready-made moves (animations) a Jabbertoon cartoon character can do, such as walk in, wave hello, hop, bow, slump, or talk with the voice. Each move has an id, a short description, its length in seconds, its page on jabbertoon.com, and links that open it in the block editor or the cartoon studio. A move is not tied to one character: the same move plays on any of the six ready-made characters (person, kid, dog, cat, bird, monster), and some suit some bodies better. Call get_move for a move's program. The optional q keeps the moves whose name, id or description contain all of its words, or that do what a word means (dance finds Groove, scared finds Cower, sleep finds Breathe and Still); notes say which were found by meaning and, for a feeling, the face a say block can show. The filter used is echoed back in filters.

report_problem
Tell Jabbertoon something is wrong
Reports a problem with Jabbertoon's tools or content to the people who run it: a tool answer that is wrong, a validator that refused a good program or passed a bad one, a move that looks wrong on a character, a link that does not open, docs that say something the engine does not do, or something missing. Unlike the other tools, this one keeps what you send: the report (kind, item, the request that produced it, and your note) is saved for a person to read. Never put personal details in it: no names, email addresses, or anything about the person you are helping.

share_link
Make a jabbertoon.com link that opens a move or a character
Turns a Jabbertoon move (a block program of kind "behaviour") or a character into a jabbertoon.com link the person can open in their browser. Everything travels inside the link after the #, so nothing is uploaded or stored, by Jabbertoon or by this tool. A move opens in the block editor, where it plays on a character (links.studio adds it to the person's moves in the cartoon studio); a character opens in the cartoon studio (links.create opens it in the character creator). Give exactly one of program, cartoon or character. No link plays a scene or a whole cartoon yet: for a program of kind "scene" or "cartoon", or a cartoon file, the answer is ok false with error code "not_yet" and no link (validate checks one now). A move or a character is checked first: one with errors gets ok false and the errors (as validate gives them) instead of a link.

validate
Check a Jabbertoon program, character, pack or cartoon
Checks a Jabbertoon block program (a move, a scene or a cartoon), a character, a pack, or a saved cartoon file with Jabbertoon's own validator, the same checks the studio, the character creator and the block editor make. Give exactly one of program, character, pack or cartoon. A talking cartoon is {"cast": {"dog": {"name": "Biscuit", "look": {"template": "dog"}}}, "program": {"v": 1, "kind": "cartoon", "scripts": [{"hat": {"on": "scene", "name": "Hello"}, "body": [{"op": "say", "who": "dog", "text": "Hi!"}]}]}}: the cast is an object keyed by ids, who names a cast id, every script starts with a scene hat, and a scene's blocks are say {who, text}, does {who, behaviour} (a move id from list_moves, or an inline move), enter, exit, place, cut, caption and mood, with wait, repeat and together. A move is a program of kind "behaviour" (get_move gives ready-made ones). The answer has ok, error_count, warning_count, and the errors and warnings (the first 50 of each, in order) as {code, where, says, fix}: where is the path of the field (e.g. scripts[0].body[2]), says is what is wrong, fix is how to fix it there when the checker knows, keeping the block's own words, speaker and fields. Fix the errors and call validate again until ok is true; warnings do not stop a program from playing, but say what the site will not do: hats that never fire on jabbertoon.com today (touch, beat, loud, every) or only in the block editor (key, click), moves that do not exist, and looks it cannot draw. Nothing you send is stored or logged.
