Crate jev_repl 

The pieces of the jev REPL, exposed so they can be driven without a terminal.

Modules

app

REPL state: the transcript, the input line, the session being built, and what each command does.

builder

Builder mode: compose a question in a form instead of a one-line command, with the JSON it will send rendered beside it as you type.

codegen

Turn the current session into a program written against this SDK.

cost

What a session costs: the tokens a request carries, the tokens its answers bring back, and the money that is at rates you supply.

editor

Sketch mode: a small text editor over one page of sketch notation. The page is parsed on every keystroke, so the gutter and the preview pane always show what the text currently means.

evaluate

Scoring a rubric against states someone has already labelled.

format

Turning answers, questions and errors into styled transcript lines.

headless

jev with no terminal in the way: a page in, an answer page out.

highlight

Small hand-rolled highlighters for the three languages this REPL shows: the JSON going over the wire, the Rust it generates, and the command line you are typing.

install

Where the jev MCP server and the jev skill go, for each agent that can host them.

installer

jev install — put the MCP server and the skill where an agent will find them.

lessons

The guided track: eleven short lessons, each with one command to try.

mcp

jev as an MCP server: the one-shot commands, offered to an agent as tools.

mock

Offline answers, so the shapes can be learned without an API key.

presets

Ready-made sessions to poke at: :preset <name>.

serve

The MCP server on a pipe: newline-delimited JSON-RPC in on stdin, the same out on stdout.

session

The thing you are building in the REPL: a state, some named questions, a model.

sketch

Sketch notation: the whole request written as one page of plain text, the way you would scribble a rubric on paper. The shape of each question is read off its punctuation, so there is nothing to select — you write what you mean and the gutter tells you what it became.

skill

The jev skill: what an agent reads to write a page that parses and a request worth sending.

ui

Layout: a status strip, the transcript, a live view of the session, and the input line.

words

Word-wise motion, and the keys that ask for it.

wrap

Word wrapping that keeps span styles, so the transcript can be scrolled by exact line count.
