## Examples
After building the `repl`, it will be available in `.lake/build/bin/repl`.
Execute it by either directly referring to its name, or `lake exe repl`.
``` sh
pantograph-repl MODULES|LEAN_OPTIONS
repl MODULES|LEAN_OPTIONS
```
The `pantograph-repl` executable must be run with a list of modules to import.
It can also accept lean options of the form `--key=value` e.g. `--pp.raw=true`.
The `repl` executable must be given with a list of modules to import. By default
it will import nothing, not even `Init`. It can also accept lean options of the
form `--key=value` e.g. `--pp.raw=true`.
The REPL loop accepts commands as single-line JSON inputs and outputs either an
`Error:` (indicating malformed command) or a JSON return value indicating the
result of a command execution. The command can be passed in one of two formats
result of a command execution. It accepts commands in one of two formats
```
command { ... }
{ "cmd": command, "payload": ... }
```
The list of available commands can be found in `Pantograph/Protocol.lean` and below. An
empty command aborts the REPL.

REPL.
Example: (~5k symbols)
```
$ pantograph Init
$ repl Init
env.catalog
env.inspect {"name": "Nat.le_add_left"}
```
Example with `mathlib4` (~90k symbols, may stack overflow, see troubleshooting)
```
$ pantograph Mathlib.Analysis.Seminorm
$ repl Mathlib.Analysis.Seminorm
env.catalog
```
Example proving a theorem: (alternatively use `goal.start {"copyFrom": "Nat.add_comm"}`) to prime the proof
