TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
|
||||
|
||||
1. Definitions.
|
||||
|
||||
"License" shall mean the terms and conditions for use, reproduction,
|
||||
and distribution as defined by Sections 1 through 9 of this document.
|
||||
|
||||
"Licensor" shall mean the copyright owner or entity authorized by
|
||||
the copyright owner that is granting the License.
|
||||
|
||||
"Legal Entity" shall mean the union of the acting entity and all
|
||||
other entities that control, are controlled by, or are under common
|
||||
control with that entity. For the purposes of this definition,
|
||||
"control" means (i) the power, direct or indirect, to cause the
|
||||
direction or management of such entity, whether by contract or
|
||||
otherwise, or (ii) ownership of fifty percent (50%) or more of the
|
||||
outstanding shares, or (iii) beneficial ownership of such entity.
|
||||
|
||||
"You" (or "Your") shall mean an individual or Legal Entity
|
||||
exercising permissions granted by this License.
|
||||
|
||||
"Source" form shall mean the preferred form for making modifications,
|
||||
including but not limited to software source code, documentation
|
||||
source, and configuration files.
|
||||
|
||||
"Object" form shall mean any form resulting from mechanical
|
||||
transformation or translation of a Source form, including but
|
||||
not limited to compiled object code, generated documentation,
|
||||
and conversions to other media types.
|
||||
|
||||
"Work" shall mean the work of authorship, whether in Source or
|
||||
Object form, made available under the License, as indicated by a
|
||||
copyright notice that is included in or attached to the work
|
||||
(an example is provided in the Appendix below).
|
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain
|
||||
separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.
|
||||
|
||||
"Contribution" shall mean any work of authorship, including
|
||||
the original version of the Work and any modifications or additions
|
||||
to that Work or Derivative Works thereof, that is intentionally
|
||||
submitted to Licensor for inclusion in the Work by the copyright owner
|
||||
or by an individual or Legal Entity authorized to submit on behalf of
|
||||
the copyright owner. For the purposes of this definition, "submitted"
|
||||
means any form of electronic, verbal, or written communication sent
|
||||
to the Licensor or its representatives, including but not limited to
|
||||
communication on electronic mailing lists, source code control systems,
|
||||
and issue tracking systems that are managed by, or on behalf of, the
|
||||
Licensor for the purpose of discussing and improving the Work, but
|
||||
excluding communication that is conspicuously marked or otherwise
|
||||
designated in writing by the copyright owner as "Not a Contribution."
|
||||
|
||||
"Contributor" shall mean Licensor and any individual or Legal Entity
|
||||
on behalf of whom a Contribution has been received by Licensor and
|
||||
subsequently incorporated within the Work.
|
||||
|
||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the
|
||||
Work and such Derivative Works in Source or Object form.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
(except as stated in this section) patent license to make, have made,
|
||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||
where such license applies only to those patent claims licensable
|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You
|
||||
meet the following conditions:
|
||||
|
||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|
||||
of your accepting any such warranty or additional liability.

Force the instantiation of delayed metavariables even if they cannot be fully

the current goal.
|

|

Since Lean 4 does not have an `Expr` constructor corresponding to delayed
|
||||
metavariables, any delayed metavariables must be recursively handled by this
|
||||
function to ensure that nested delayed metavariables can be properly processed.
|
||||
The caveat is this recursive call will lead to infinite recursion if a loop
|
||||
between metavariable assignment exists.
|
||||
|
||||
This function ensures any metavariable in the result is either
|
||||
1. Delayed assigned with its pending mvar not assigned in any form
|
||||
2. Not assigned (delay or not)

# Pantograph
|
||||
|
||||
An interaction system for Lean 4.
|
||||
A Machine-to-Machine interaction system for Lean 4.
|
||||
|
||||
|
||||
|
||||
Pantograph provides interfaces to execute proofs, construct expressions, and
|
||||
examine the symbol list of a Lean project for machine learning.
|
||||
|
||||
See [documentations](doc/rationale.md) for design rationale and references.
|
||||
|
||||
## Installation
|
||||
|
||||
Install `elan` and `lean4`. Then, execute
|
||||
For Nix users, run
|
||||
``` sh
|
||||
nix build .#{sharedLib,executable}
|
||||
```
|
||||
to build either the shared library or executable.
|
||||
|
||||
Install `lake` and `lean` fixed to the version of the `lean-toolchain` file, and
|
||||
run
|
||||
|
||||
``` sh
|
||||
lake build
|
||||
```
|
||||
Then, setup the `LEAN_PATH` environment variable so it contains the library path of lean libraries. The libraries must be built in advance. For example, if `mathlib4` is stored at `../lib/mathlib4`,
|
||||
``` sh
|
||||
LIB="../lib"
|
||||
LIB_MATHLIB="$LIB/mathlib4/lake-packages"
|
||||
export LEAN_PATH="$LIB/mathlib4/build/lib:$LIB_MATHLIB/aesop/build/lib:$LIB_MATHLIB/Qq/build/lib:$LIB_MATHLIB/std/build/lib"
|
||||
This builds the executable in `.lake/build/bin/pantograph-repl`.
|
||||
|
||||
LEAN_PATH=$LEAN_PATH build/bin/pantograph $@
|
||||
```
|
||||
Note that `lean-toolchain` must be present in the `$PWD` in order to run Pantograph! This is because Pantograph taps into Lean's internals.
|
||||
|
||||
## Usage
|
||||
## Executable Usage
|
||||
|
||||
``` sh
|
||||
build/bin/pantograph OPTIONS|MODULES
|
||||
pantograph-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 loop accepts commands as single-line JSON inputs and outputs either an
|
||||
`Error:` (indicating malformed command) or a json return value indicating the
|
||||
`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
|
||||
```
|
||||
command { ... }
|
||||
{ "cmd": command, "payload": ... }
|
||||
```
|
||||
The list of available commands can be found in `Pantograph/Commands.lean`. An
|
||||
The list of available commands can be found in `Pantograph/Protocol.lean` and below. An
|
||||
empty command aborts the REPL.
|
||||
|
||||
The `Pantograph` executable must be run with a list of modules to import. It can
|
||||
also accept options of the form `--key=value` e.g. `--pp.raw=true`.
|
||||
|
||||
Example: (~5k symbols)
|
||||
```
|
||||
$ build/bin/Pantograph Init
|
||||
catalog
|
||||
inspect {"name": "Nat.le_add_left"}
|
||||
$ pantograph Init
|
||||
env.catalog
|
||||
env.inspect {"name": "Nat.le_add_left"}
|
||||
```
|
||||
Example with `mathlib4` (~90k symbols, may stack overflow, see troubleshooting)
|
||||
```
|
||||
$ lake env build/bin/Pantograph Mathlib.Analysis.Seminorm
|
||||
catalog
|
||||
$ pantograph Mathlib.Analysis.Seminorm
|
||||
env.catalog
|
||||
```
|
||||
Example proving a theorem: (alternatively use `proof.start {"copyFrom": "Nat.add_comm"}`) to prime the proof
|
||||
Example proving a theorem: (alternatively use `goal.start {"copyFrom": "Nat.add_comm"}`) to prime the proof
|
||||
```
|
||||
$ env build/bin/Pantograph Init
|
||||
proof.start {"expr": "∀ (n m : Nat), n + m = m + n"}
|
||||
proof.tactic {"treeId": 0, "stateId": 0, "goalId": 0, "tactic": "intro n m"}
|
||||
proof.tactic {"treeId": 0, "stateId": 1, "goalId": 0, "tactic": "assumption"}
|
||||
proof.printTree {"treeId": 0}
|
||||
proof.tactic {"treeId": 0, "stateId": 1, "goalId": 0, "tactic": "rw [Nat.add_comm]"}
|
||||
proof.printTree {"treeId": 0}
|
||||
$ pantograph Init
|
||||
goal.start {"expr": "∀ (n m : Nat), n + m = m + n"}
|
||||
goal.tactic {"stateId": 0, "goalId": 0, "tactic": "intro n m"}
|
||||
goal.tactic {"stateId": 1, "goalId": 0, "tactic": "assumption"}
|
||||
goal.delete {"stateIds": [0]}
|
||||
stat {}
|
||||
goal.tactic {"stateId": 1, "goalId": 0, "tactic": "rw [Nat.add_comm]"}
|
||||
stat
|
||||
```
|
||||
where the application of `assumption` should lead to a failure.
|
||||
|
||||
## Commands
|
||||
For a list of commands, see [REPL Documentation](doc/repl.md).
|
||||
|
||||
See `Pantograph/Commands.lean` for a description of the parameters and return values in Json.
|
||||
- `catalog`: Display a list of all safe Lean symbols in the current context
|
||||
- `inspect {"name": <name>}`: Show the type and package of a given symbol
|
||||
- `clear`: Delete all cached expressions and proof trees
|
||||
- `expr.type {"expr": <expr>}`: Determine the type of an expression and round-trip it
|
||||
- `proof.start {["name": <name>], ["expr": <expr>], ["copyFrom": <symbol>]}`: Start a new proof state from a given expression or symbol
|
||||
- `proof.tactic {"treeId": <id>, "stateId": <id>, "goalId": <id>, "tactic": string}`: Execute a tactic on a given proof state
|
||||
- `proof.printTree {"treeId": <id>}`: Print the topological structure of a proof tree
|
||||
### Project Environment
|
||||
|
||||
## Troubleshooting
|
||||
To use Pantograph in a project environment, setup the `LEAN_PATH` environment
|
||||
variable so it contains the library path of lean libraries. The libraries must
|
||||
be built in advance. For example, if `mathlib4` is stored at `../lib/mathlib4`,
|
||||
the environment might be setup like this:
|
||||
|
||||
``` sh
|
||||
LIB="../lib"
|
||||
LIB_MATHLIB="$LIB/mathlib4/.lake"
|
||||
export LEAN_PATH="$LIB/mathlib4/build/lib:$LIB_MATHLIB/aesop/build/lib:$LIB_MATHLIB/Qq/build/lib:$LIB_MATHLIB/std/build/lib"
|
||||
|
||||
LEAN_PATH=$LEAN_PATH build/bin/pantograph $@
|
||||
```
|
||||
The `$LEAN_PATH` executable of any project can be extracted by
|
||||
``` sh
|
||||
lake env printenv LEAN_PATH
|
||||
```
|
||||
|
||||
### Troubleshooting
|
||||
|
||||
If lean encounters stack overflow problems when printing catalog, execute this before running lean:
|
||||
```sh
|
||||
ulimit -s unlimited
|
||||
```
|
||||
|
||||
## Testing
|
||||
## Library Usage
|
||||
|
||||
The tests are based on `LSpec`. To run tests,
|
||||
`Pantograph/Library.lean` exposes a series of interfaces which allow FFI call
|
||||
with `Pantograph` which mirrors the REPL commands above. It is recommended to
|
||||
call Pantograph via this FFI since it provides a tremendous speed up.
|
||||
|
||||
The executable can be used as-is, but linking against the shared library
|
||||
requires the presence of `lean-all`. Note that there isn't a 1-1 correspondence
|
||||
between executable (REPL) commands and library functions.
|
||||
|
||||
Inject any project path via the `pantograph_init_search` function.
|
||||
|
||||
## Developing
|
||||
|
||||
A Lean development shell is provided in the Nix flake.
|
||||
|
||||
### Testing
|
||||
|
||||
The tests are based on `LSpec`. To run tests, use either
|
||||
``` sh
|
||||
test/all.sh
|
||||
nix flake check
|
||||
```
|
||||
or
|
||||
``` sh
|
||||
lake test
|
||||
```
|
||||
You can run an individual test by specifying a prefix
|
||||
|
||||
``` sh
|
||||
lake test -- "Tactic/No Confuse"
|
||||
```

# 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.
|
||||
|
||||
## Caveats and Limitations
|
||||
|
||||
Pantograph does not exactly mimic Lean LSP's behaviour. That would not grant the
|
||||
flexibility it offers. To support tree search means Pantograph has to act
|
||||
differently from Lean in some times, but never at the sacrifice of soundness.
|
||||
|
||||
- When Lean LSP says "don't know how to synthesize placeholder", this indicates
|
||||
the human operator needs to manually move the cursor to the placeholder and
|
||||
type in the correct expression. This error therefore should not halt the proof
|
||||
process, and the placeholder should be turned into a goal.
|
||||
- When Lean LSP says "unresolved goals", that means a proof cannot finish where
|
||||
it is supposed to finish at the end of a `by` block. Pantograph will raise the
|
||||
error in this case, since it indicates the termination of a proof search branch.
|
||||
- `pick_goal` or `swap` will not work since they run contrary to tree search
|
||||
paradigms. However, if there are tactics which perform non-trivial operations
|
||||
to multiple goals at the same time, this constrain could potentially be
|
||||
relaxed at a cost of great bookkeeping overhead to the user.
|
||||
|
||||
Pantograph cannot perform things that are inherently constrained by Lean. These
|
||||
include:
|
||||
|
||||
- If a tactic loses track of metavariables, it will not be caught until the end
|
||||
of the proof search. This is a bug in the tactic itself.
|
||||
- Timeouts for executing tactics is not available. Maybe this will change in the
|
||||
future.
|
||||
- Interceptions of parsing errors generally cannot be turned into goals (e.g.
|
||||
`def mystery : Nat := :=`) due to Lean's parsing system.

||||
|
||||
## 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.
|
||||
* `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>, newConstants: <bool> }`: Executes the Lean frontend on
|
||||
a file, collecting the tactic invocations (`"invocations": true`), the
|
||||
sorrys and type errors into goal states (`"sorrys": true`), and new constants
|
||||
(`"newConstants": true`). In the case of `sorrys`, this command additionally
|
||||
outputs the position of each captured `sorry`.
|
||||
|
||||
## 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.
