### Commands
|
||||
|
||||
See `Pantograph/Protocol.lean` for a description of the parameters and return values in JSON.
|
||||
* `reset`: Delete all cached expressions and proof trees
|
||||
* `stat`: Display resource usage
|
||||
* `expr.echo {"expr": <expr>, "type": <optional expected type>, ["levels": [<levels>]]}`: Determine the
|
||||
type of an expression and format it.
|
||||
* `env.catalog`: Display a list of all safe Lean symbols in the current environment
|
||||
* `env.inspect {"name": <name>, "value": <bool>}`: Show the type and package of a
|
||||
given symbol; If value flag is set, the value is printed or hidden. By default
|
||||
only the values of definitions are printed.
|
||||
* `options.set { key: value, ... }`: Set one or more options (not Lean options; those
|
||||
have to be set via command line arguments.), for options, see `Pantograph/Protocol.lean`
|
||||
|
||||
One particular option for interest for machine learning researchers is the
|
||||
automatic mode (flag: `"automaticMode"`). By default it is turned on, with
|
||||
all goals automatically resuming. This makes Pantograph act like a gym,
|
||||
with no resumption necessary to manage your goals.
|
||||
* `options.print`: Display the current set of options
|
||||
* `goal.start {["name": <name>], ["expr": <expr>], ["levels": [<levels>]], ["copyFrom": <symbol>]}`:
|
||||
Start a new proof from a given expression or symbol
|
||||
* `goal.tactic {"stateId": <id>, "goalId": <id>, ...}`: Execute a tactic string on a
|
||||
given goal. The tactic is supplied as additional key-value pairs in one of the following formats:
|
||||
- `{ "tactic": <tactic> }`: Execute an ordinary tactic
|
||||
- `{ "expr": <expr> }`: Assign the given proof term to the current goal
|
||||
- `{ "have": <expr>, "binderName": <name> }`: Execute `have` and creates a branch goal
|
||||
- `{ "calc": <expr> }`: Execute one step of a `calc` tactic. Each step must
|
||||
be of the form `lhs op rhs`. An `lhs` of `_` indicates that it should be set
|
||||
to the previous `rhs`.
|
||||
- `{ "conv": <bool> }`: Enter or exit conversion tactic mode. In the case of
|
||||
exit, the goal id is ignored.
|
||||
* `goal.continue {"stateId": <id>, ["branch": <id>], ["goals": <names>]}`:
|
||||
Execute continuation/resumption
|
||||
- `{ "branch": <id> }`: Continue on branch state. The current state must have no goals.
|
||||
- `{ "goals": <names> }`: Resume the given goals
|
||||
* `goal.remove {"stateIds": [<id>]}"`: Drop the goal states specified in the list
|
||||
* `goal.print {"stateId": <id>}"`: Print a goal state
|
||||
* `frontend.process { ["fileName": <fileName>",] ["file": <str>], invocations:
|
||||
<bool>, sorrys: <bool> }`: Executes the Lean frontend on a file, collecting
|
||||
either the tactic invocations (`"invocations": true`) or the sorrys into goal
|
||||
states (`"sorrys": true`)
|
||||
|
||||
### Errors
|
||||
|
||||
When an error pertaining to the execution of a command happens, the returning JSON structure is
|
||||
|
||||

||||

Common error forms:
|
||||
* `command`: Indicates malformed command structure which results from either
|
||||
invalid command or a malformed JSON structure that cannot be fed to an
|
||||
individual command.
|
||||
* `index`: Indicates an invariant maintained by the output of one command and
|
||||
input of another is broken. For example, attempting to query a symbol not
|
||||
existing in the library or indexing into a non-existent proof state.
|
||||
For a list of commands, see [REPL Documentation](doc/repl.md).

# Design Rationale
|
||||
|
||||
A great problem in machine learning is to use ML agents to automatically prove
|
||||
mathematical theorems. This sort of proof necessarily involves *search*.
|
||||
Compatibility for search is the main reason for creating Pantograph. The Lean 4
|
||||
LSP interface is not conducive to search. Pantograph is designed with this in
|
||||
mind. It emphasizes the difference between 3 views of a proof:
|
||||
|
||||
- **Presentation View**: The view of a written, polished proof. e.g. Mathlib and
|
||||
math papers are almost always written in this form.
|
||||
- **Search View**: The view of a proof exploration trajectory. This is not
|
||||
explicitly supported by Lean LSP.
|
||||
- **Kernel View**: The proof viewed as a set of metavariables.
|
||||
|
||||
Pantograph enables proof agents to operate on the search view.
|
||||
|
||||
## Name
|
||||
|
||||
The name Pantograph is a pun. It means two things
|
||||
- A pantograph is an instrument for copying down writing. As an agent explores
|
||||
the vast proof search space, Pantograph records the current state to ensure
|
||||
the proof is sound.
|
||||
- A pantograph is also an equipment for an electric train. It supplies power to
|
||||
a locomotive. In comparison the (relatively) simple Pantograph software powers
|
||||
theorem proving projects.

See `Pantograph/Protocol.lean` for a description of the parameters and return values in JSON.
|
||||
* `reset`: Delete all cached expressions and proof trees
|
||||
* `stat`: Display resource usage
|
||||
* `expr.echo {"expr": <expr>, "type": <optional expected type>, ["levels": [<levels>]]}`: Determine the
|
||||
type of an expression and format it.
|
||||
* `env.catalog`: Display a list of all safe Lean symbols in the current environment
|
||||
* `env.inspect {"name": <name>, "value": <bool>}`: Show the type and package of a
|
||||
given symbol; If value flag is set, the value is printed or hidden. By default
|
||||
only the values of definitions are printed.
|
||||
* `env.save { "path": <fileName> }`, `env.load { "path": <fileName> }`: Save/Load the
|
||||
current environment to/from a file
|
||||
* `options.set { key: value, ... }`: Set one or more options (not Lean options; those
|
||||
have to be set via command line arguments.), for options, see `Pantograph/Protocol.lean`
|
||||
|
||||
One particular option for interest for machine learning researchers is the
|
||||
automatic mode (flag: `"automaticMode"`). By default it is turned on, with
|
||||
all goals automatically resuming. This makes Pantograph act like a gym,
|
||||
with no resumption necessary to manage your goals.
|
||||
* `options.print`: Display the current set of options
|
||||
* `goal.start {["name": <name>], ["expr": <expr>], ["levels": [<levels>]], ["copyFrom": <symbol>]}`:
|
||||
Start a new proof from a given expression or symbol
|
||||
* `goal.tactic {"stateId": <id>, "goalId": <id>, ...}`: Execute a tactic string on a
|
||||
given goal. The tactic is supplied as additional key-value pairs in one of the following formats:
|
||||
- `{ "tactic": <tactic> }`: Execute an ordinary tactic
|
||||
- `{ "expr": <expr> }`: Assign the given proof term to the current goal
|
||||
- `{ "have": <expr>, "binderName": <name> }`: Execute `have` and creates a branch goal
|
||||
- `{ "calc": <expr> }`: Execute one step of a `calc` tactic. Each step must
|
||||
be of the form `lhs op rhs`. An `lhs` of `_` indicates that it should be set
|
||||
to the previous `rhs`.
|
||||
- `{ "conv": <bool> }`: Enter or exit conversion tactic mode. In the case of
|
||||
exit, the goal id is ignored.
|
||||
* `goal.continue {"stateId": <id>, ["branch": <id>], ["goals": <names>]}`:
|
||||
Execute continuation/resumption
|
||||
- `{ "branch": <id> }`: Continue on branch state. The current state must have no goals.
|
||||
- `{ "goals": <names> }`: Resume the given goals
|
||||
* `goal.remove {"stateIds": [<id>]}"`: Drop the goal states specified in the list
|
||||
* `goal.print {"stateId": <id>}"`: Print a goal state
|
||||
* `goal.save { "id": <id>, "path": <fileName> }`, `goal.load { "path": <fileName> }`:
|
||||
Save/Load a goal state to/from a file. The environment is not carried with the
|
||||
state. The user is responsible to ensure the sender/receiver instances share
|
||||
the same environment.
|
||||
* `frontend.process { ["fileName": <fileName>,] ["file": <str>], invocations:
|
||||
<bool>, sorrys: <bool> }`: Executes the Lean frontend on a file, collecting
|
||||
either the tactic invocations (`"invocations": true`) or the sorrys into goal
|
||||
states (`"sorrys": true`)
|
||||
|
||||
## Errors
|
||||
|
||||
When an error pertaining to the execution of a command happens, the returning JSON structure is
|
||||
|
||||
``` json
|
||||
{ "error": "type", "desc": "description" }
|
||||
```
|
||||
Common error forms:
|
||||
* `command`: Indicates malformed command structure which results from either
|
||||
invalid command or a malformed JSON structure that cannot be fed to an
|
||||
individual command.
|
||||
* `index`: Indicates an invariant maintained by the output of one command and
|
||||
input of another is broken. For example, attempting to query a symbol not
|
||||
existing in the library or indexing into a non-existent proof state.
