Union types (!3192 by alistair.obrien)
Details :
feat(lang): Improves support for discriminant unions by adding union types.
A union type describes a value that can be one of several types. We use the vertical bar (
|
) to separate the types. For instance,int | string
is the type of a value that can be either anint
or astring
.const a = { a: 1 } as { a: int } | { b: bool };Common Fields
When working with a union type of records, we can only access members common to all types in the union.
type Car = {driver: string;fuel: nat;}type Bike = {driver: string;hasTrainingWheels: bool;}const getDriver = (vehicle: Car | Bike): string => vehicle.driver;If a value has the type
Car | Bike
, we can only accessdriver
because it is the only member common to both types. We cannot accessfuel
orhasTrainingWheels
without additional type checks, as accessingfuel
on aBike
would result in a runtime error.Discriminant Unions
A common pattern for using union types is to include a single field with a singleton type to distinguish between the types. This allows the type checker to infer the specific type in a conditional statement.
type IntValue = { typ: "INT"; x: int };type StrValue = { typ: "STR"; s: string };type Value = IntValue | StrValue;All types in the
Value
union have a common fieldtyp
. Sincetyp
is a singleton type, we can compare its value to determine the specific type being used. Here’s how to use a switch statement to narrow down the type:const valueToInt = (val: Value): int => {switch (val.typ) {case "INT":return val.x;case "STR":return int(String.length(val.s));}return -1;}In this example,
typ
helps to discriminate between theIntValue
andStrValue
types, allowing us to safely access their specific fields.[#2183] Add LSP runtime analytics (!3176 by heitor.toledo)
Details :
The language server can now collect analytics such as the number of restarts, execution time of methods, and number of crashes. Analytics are sent only if the user has agreed to let LIGO collect analytics.

Details :
Makes completions work for polymorphic record types.
[#2185] Do not check for pattern anomalies on type mismatch with error recovery (!3179 by heitor.toledo)
Details :
If typer error recovery is enabled (on for the language server), and the user writes code where there is a mismatch between a scrutinee's type and a pattern's type, it will probably lead to a crash. For example, in the following code:
type t = Unitlet Unit = ()let () =match () with| Unit -> ()The scrutinee (
Unit : t
) and the pattern (() : unit
) have mismatched types (t
is not the same asunit
), leading to a crash.With the changes from this changelog, this crash should no longer occur.
[#2184] Forbid empty modules in the parser (!3177 by heitor.toledo)
Details :
Fixed "Failure tl" crash in the compiler and language server when writing an empty module in CameLIGO.

[#2084] Add attribute for TZIP-16 compatibility (!3086 by Martoon)
Details :
Added
tzip16_compatible
attribute for indicating that the given storage value is expected to satisfy TZIP-16 metadata rules.This attribute does nothing on itself at the moment, but some IDEs may provide additional verification.
Example (CameLIGO):
type storage ={data : int;metadata : (string, bytes) big_map}[@tzip16_compatible]let storage_sample : storage ={data = 5;metadata =Big_map.literal[("",[%bytes"https://ipfs.io/ipfs/QmSBc8QuynU7bArUGtjwCRhZUbJyZQArrczKnqM7hZPtfV"])]}Example (JsLIGO):
type storage = { data: int; metadata: big_map<string, bytes> }@tzip16_compatibleconst storage_sample: storage = {data: 5,metadata: Big_map.literal(list([["",(bytes`https://ipfs.io/ipfs/QmSBc8QuynU7bArUGtjwCRhZUbJyZQArrczKnqM7hZPtfV`)]]))}
Fixed :

Performance :
Draft: [#2143] Optimizations in references and nanopasses (!3120 by DK318)
Details :
Improved performance for LSP and compilation pipeline.
The LSP should now take less time between keystrokes.
This is done by reducing the number of tree traversals in nanopasses compilation stage.
[#2143] Reuse the normalization table LSP-wide (!3118 by heitor.toledo)
Details :
The LSP should now take less time between keystrokes.
This is done by creating a table for file canonicalization, which accounted for a huge time spent by the LSP.
[#2143] New, faster algorithm for scopes completion, and caching for path normalization (!3117 by heitor.toledo)
Details :
The LSP should now have faster times between keystrokes.
This happens because the LSP would previously calculate all scopes for all points between keystrokes for use in completions. Now, it will do so lazily, only when document symbols or completions for scopes are requested. Moreover, a new algorithm was implemented, that should be much faster.
Also, the LSP would try to normalize paths in a loop for all definitions in case a document symbol or inlay hints request was received. It will now cache those to avoid normalizing paths that were previously normalized, giving a performance boost.

that can take a list expression that may not be a literal.Deprecated some functions and added equivalent ones with a better name (e.g,List.head
andList.head_opt
). Added either a functionsize
orlength
so all modules have both.Same forsub
andslice
whenever meaningful.Added functionsempty
in all modules.Simplified implementations, made them uniform (order of constructors in pattern maching, for example), tried to avoid relying on built-ins.The module Option was messy.Draft: [#2101] Find all references project-wise (!3060 by heitor.toledo)
Details :
"Find All References"/"Go to References" and "Rename" will now look for all references from the project root (closest directory with
ligo.json
looking from the current path and parents). Previously, those references would only be found in files that had been previously opened.Draft: [#1676] Add missing items to scopes (!3042 by DK318)

Suppress opt_cond Michelson optimization for debugging (!2935 by tomjack)
Details :
Disable
opt_cond
Michelson optimization when debugging.Fixes link-dev version parsing (!2931 by shubham-kumar)
Details :
Fixes #2077 by adding an additional check on the input string when parsing the nodes in the lockfile. This check of input string looks for the default node which is why the install part is breaking. In future the default node would be removed. So this is a fix to manage the temporary pattern of lockfile which was adopted to carry the same pattern of lockfile as esy.

File import: make
export
mandatory to export values/types/namespaces when importing modules from other files (!2796 by er433)Details :
When importing a file with
#import
, every definition was imported, even those not marked withexport
explicitly in JsLIGO, e.g. in previous versions we had:$ ligo compile expression jsligo y --init-file modules_export_importer.jsligo42$ cat modules_export_imported.jsligotype t = int;const x : t = 42;$ cat modules_export_importer.jsligo#import "modules_export_imported.jsligo" "M"const y : M.t = M.x;After this change,

Details :
New pattern matching in JsLIGO
It follows a variant of tc39 proposal pattern matching.
E.g.
match (action) {when(Add(n)): n;when(Sub(n)): -n;}Draft: Default to @layout:comb everywhere (!1816 by tomjack)
Details :
Made @layout:comb the default layout for all variants, records, and tuple (
[a, b, ...]
/a * b * ...
) types.This is a BREAKING CHANGE!
If your contract needs to interoperate with existing contracts, contracts compiled with previous LIGO versions or other compilers, or existing standards or off-chain tools/clients/indexers/etc, you MUST verify this interop still works after this change. Testing with
ligo test
or by compiling a fresh set of contracts is generally not sufficient! You must test against the actual contracts as they are deployed or will be deployed.For more info, see the FAQ pages on how to deal with this change and why this happened.
Added :
deprecate --package-management-alpha flag (!2909 by shubham-kumar)
Details :
Package management backend no longer uses esy by default. Using esy is now opt-in and requires

Details :
Underscore is now accepted everywhere a variable is accepted.
CLI: Forgot password command (!2875 by prometheansacrifice)
Details :
Adds a CLI command for ligo registry users to reset their password.
ligo registry forgot-passwordFor security reasons, existing users would need a valid session token already since we dont have their emails. The CLI would ask them for their email to send the password reset link. If they don't have a valid session token, they'll have to reach out to support.
New users dont need this, since we start asking their emails when they create an account with us.
Code injection: new code injection for directly using
CREATE_CONTRACT
+of_file
(!2860 by er433)Details :
A new code injection is available for calling
CREATE_CONTRACT
of a.tz
file.In CameLIGO,
[%create_contract_of_file "file.tz"]
will be expanded to a function of typekey_hash option -> tez -> 's -> operation * address
. It can be used as follows:[@entry]let main (u : unit) (_ : unit) : operation list * unit =let op, _addr = [%create_contract_of_file "./interpreter_tests/contract_under_test/compiled.tz"] None 1tez u in[op], ()In JsLIGO,
(create_contract_of_file
file.tz)
will be expanded to a function of type<s>(k: option<key_hash>, t: tez, s:storage) => [operation, address]
. It can be used as follows:@entryconst main = (u : unit, _ : unit) : [list<operation>, unit] => {let [op, _addr] = (create_contract_of_file `./interpreter_tests/contract_under_test/compiled.tz`)(None(), 1tez, u);return [list([op]), []]}Notice that the parameter passed for storage must have a type that compiles to the type expected as storage of the contract in the
.tz
file. In case of a mismatch, a type error will be present when typing the resulting Michelson contract. In the examples above, the contract's storage type isunit
, and the argument passed as storage to the function (u
) has that type.Some minor improvements on the refactoring of JsLIGO (!2853 by rinderkn)

storage
with an appropriate storage type.In addition, more diagnostics will be shown, such as ones for unused variables.
Package management: use ligo.json instead of package.json or esy.json (!2817 by prometheansacrifice)
Details :
Users can now use a
ligo.json
file to manage dependencies instead ofpackage.json
Existing projects withesy.json

Added :
Implicit casting: booleans (!2704 by er433)
Details :
When checking an expression for a boolean, certain values are "casted" implicitly:
n : nat

is true iff0 < Map.size m
Now values of types such asnat
,int
,tez
,string
,bytes
, lists, maps and sets can be used in conditions, and are casted automatically tobool
:const f = (s : list<int>) => {let _s = s;let k = 0;while (_s && k < 3) {_s = Option.unopt(List.tail_opt(_s));k++;};return k;};[#1698][#1674] Make LSP hovers prettier (!2465 by Sorokin-Anton)

JsLIGO: simple interfaces for namespace contracts (!2631 by er433)
Details :
There's a new
interface
keyword for defining interfaces to be used in contracts (as namespaces):interface ID {type storage;type ret = [list<operation>, storage];@entry const increment : (k: int, s: storage) => ret;@entry const decrement : (k: int, s: storage) => ret;@entry const reset : (_u: unit, s: storage) => ret;};namespace IncDec implements ID {type storage = int;type ret = [list<operation>, storage];@entryconst increment = (delta : int, store : storage) : ret =>[list([]), store + delta];@entryconst decrement = (delta : int, store : storage) : ret =>[list([]), store - delta];@entryconst reset = (_ : unit, _ : storage) : ret =>[list([]), 0];};Using
implements
, when defining a namespace, we can check that the namespace (contract) implements the interface. Type declarations in interfaces can be left without definition (e.g.storage
above), and the implementation can choose the concrete instance for the type.Move to Nairobi (!2608 by prometheansacrifice)

Details :
Why
Deprecation of Pascaligo has been done following the result of a google form.
After deprecation, community disagree. Looks like the community who answer to form is not representative to the one who use the compiler. We want to have a better understanding of our users for the future.
For this we will bring analytics into ligo which gonna be passive collection of feedback from our user.
Agreement
Interactive
Because privacy is important for us, datas are anonymized. If you don't want to collect data you can deny. Still possible to change your mind by using
ligo analytics accept
orligo analytics deny
Agreement answer will be stored in ~/.ligo/term_acceptance.Docker, non-interactive
In docker analytics is activated by default. It's possible to use the environment variable LIGO_SKIP_ANALYTICS or the flag
--skip-analytics
describe belowUsing the CLI
A new flag
--skip-analytics
has been introduced on every command to skip analytics collection once.Through environment variable
If the environment variable LIGO_SKIP_ANALYTICS is set, it'll skip analytics
How datas are anonymized
To identify your project, unique ID is generated and stored in
.ligo/repository_id
. Commit and push this file will help us to understand our users.To identify you as user, a file is generated in
~/.ligo/user_id
. If you are using ligo in docker. user_id will not be generated and replaced bydocker
in our data.If you denied analytics, these file still generated
CI
If ligo is used through scripts or CI analytics will not be collected.
If your CI use docker, Use the new image ligo_ci to avoid metrics to be collected.
Analytics example
Example of data collected : When user use compile command. We collect the id of the user, the id of the project, the version of ligo used, the syntax and protocol used and also the size of the project which has been compiled. When user use ligo init. We collect the id of the user, the id of the project, the version of ligo used, the syntax and protocol used and also the template used to generate project

Draft: [#1694] Disallow looking for defs from stdlib in rename/definition/type (!2543 by heitor.toledo)
Details :
The LSP previously allowed the users to try to see the definition of things defined in the stdlib. However, the stdlib is not available on the user's computer, so there is nothing to show.
To make things worse, the user could try to rename stdlib definitions and the LSP would try (but only rename local usages, not the definition).
For now, these operations are disallowed.

Attribute for entries (!2379 by er433)
Details :
New attribute
@entry
allows to define entries for a module/namespace, or from the top-level of a file.For example, the file
contract.jsligo
type storage = int;// @entryconst increment = (action: int, store: storage) : [list <operation>, storage] => [list([]), store + action];// @entryconst decrement = (action: int, store: storage) : [list <operation>, storage] => [list([]), store - action];// @entryconst reset = (_u: unit, _store: storage) : [list<operation>, storage] => [list([]), 0];can be compiled directly:
$ ligo compile contract contract.jsligo{ parameter (or (or (int %decrement) (int %increment)) (unit %reset)) ;storage int ;code { UNPAIR ;IF_LEFT { IF_LEFT { SWAP ; SUB } { ADD } } { DROP 2 ; PUSH int 0 } ;NIL operation ;PAIR } }Moreover, when using the testing framework, a
contract_of
keyword can be used to originate a module as a contract with the help of the new functionTest.originate_module
:$ cat src/test/contracts/interpreter_tests/test_originate_module.jsligonamespace C {type storage = int;// @entryconst increment = (action: int, store: storage) : [list <operation>, storage] => [list([]), store + action];// @entryconst decrement = (action: int, store: storage) : [list <operation>, storage] => [list([]), store - action];};const test_increment = (() => {let initial_storage = 42;let [taddr, _, _] = Test.originate_module(contract_of(C), initial_storage, 0 as tez);let contr = Test.to_contract(taddr);let _ = Test.transfer_to_contract_exn(contr, (Increment (1)), 1 as mutez);return assert(Test.get_storage(taddr) == initial_storage + 1);}) ();$ ligo run test src/test/contracts/interpreter_tests/test_originate_module.jsligoEverything at the top-level was executed.- test_increment exited with value ().Breaking changes
Notice that this feature is breaking as
contract_of
becomes a keyword, rending invalid contracts that use this name as a variable. In this case, the fix is simple, and just amounts to change the name of the variable, or use@contract_of
:$ cat contract.jsligo// @entryconst increment = (action: int, store: int) : [list <operation>, int] => [list([]), store + action];const contract_of = 42;$ ligo compile contract contract.jsligoFile "contract.jsligo", line 4, characters 6-17:3 |4 | const contract_of = 42;Ill-formed value declaration.At this point, a pattern is expected, e.g. a variable.After modifying
contract.jsligo
with@contract_of
:$ cat contract.jsligo// @entryconst increment = (action: int, store: int) : [list <operation>, int] => [list([]), store + action];const @contract_of = 42;$ ligo compile contract contract.jsligo{ parameter int ;storage int ;code { UNPAIR ; ADD ; NIL operation ; PAIR } }This MR also modifies the parameters for the sub-command

[JsLIGO] Update syntax for generic functions (!2315 by melwyn95)
Details :
In JsLIGO, the syntax for defining generic functions was misleading.
This MR fixes this issue by adding the syntatic contruct to bind type variables in function expressions.
Before
const concat : <T>(xs : list<T>, ys : list<T>) => list<T> = (xs : list<T>, ys : list<T>) : list<T> => {let f = ([x, ys] : [T, list<T>]) : list<T> => list([x, ...ys]);return List.fold_right(f, xs, ys)}Before the type variables were bound in the LHS type annotation in the type expression.
After
const concat = <T>(xs : list<T>, ys : list<T>) : list<T> => {let f = ([x, ys] : [T, list<T>]) : list<T> => list([x, ...ys]);return List.fold_right(f, xs, ys)}After this change type variables can be bound in function expression like above.

JsLIGO: abstractor generate curried definitions (!2241 by er433)
Details :
Previously, multiparameter functions in JsLIGO were compiled to a function taking a tuple of parameters.
After this MR, multiparameter functions in JsLIGO are compiled to curried functions.
Contracts do still require taking a tuple
(parameter, storage)
(as in Michelson). However, LIGO will transform curried contracts to its uncurried form when usingcompile contract
. The same is true for views, taking still tuples(argument, storage)
, but curried views will be uncurried automatically as well.New functions are introduced at top-level:
val curry : ('a -> 'b -> 'c) -> ('a * 'b -> 'c)``val uncurry : ('a * 'b -> 'c) -> 'a -> 'b -> 'c
For testing,Test.originate
will take an curried contract of the formparameter -> storage -> operation list * storage
. The old (uncurried) alternative is still available asTest.originate_uncurried
.
Added :
[Chore] Add a changelog documenting the initial write of the LSP (!2393 by heitor.toledo)
Details :
Add a new subcommand (
ligo lsp
) whose purpose is to allow LSP clients (Visual Studio Code, Emacs, Vim, etc) to communicate with the new LIGO Language Server, which is being rewritten in OCaml. This command is not meant to be launched manually by users, but rather by editors. The rewrite was officially made in !2303.The initial release supports diagnostics (errors only), go to definition, hover, rename (only in open files), references (only in open files), and type definition.
As the rewrite is new, it does not yet support feature parity with the old language server, and bugs are to be expected.
Other LSP features (hover, folding range, document link, warnings for diagnostics, prepare rename) have since been implemented in other merge requests.
Official support for the Vim, Emacs, and Visual Studio Code plugins will come soon, as well as the VS Code plugin release on the Marketplace and OpenVSX.
[#1648] Implement folding range for the LSP (!2371 by heitor.toledo)
Details :
Folding ranges allow the language server client to collapse or expand regions of code. Although some clients like Visual Studio Code can try to automatically deduce ranges based on regions, others like Emacs or Vim might not, so we implement the folding range requests from LSP in
ligo lsp

New functions:
Test.print
,Test.println
,Test.eprint
,Test.to_string
,Test.nl
andTest.chr
These new functions provide more fine-grained printing.
val Test.print : string -> unit
: prints an string to stdout.val Test.println : string -> unit
: prints an string to stdout, adding a newline at the end.val Test.eprint : string -> unit
: prints an string to stderr.val Test.to_string : 'a -> string
: turns a value of a given type into astring
(internally using the same conversion asTest.log
)val Test.nl : string
: a string containing only a newline.Test.chr : nat -> string option
: turns a nat in the range [0, 255] to an string consisting of only the corresponding char.Testing framework: improvement on random generation and module PBT (!1799 by er433)
Details :
A new module
Test.PBT
This new module is introduced to do simple property-based testing. It's composed of:
val gen : 'a gen
: gives a generator for type'a
(must be annotated).val gen_small : 'a gen
: : gives a small generator for type'a
(must be annotated).val make_test : 'a gen -> ('a -> bool) -> 'a pbt_test
: creates a test from a generator and a property.val run : 'a pbt_test -> nat -> 'a pbt_result
: runs a test for a given number of tries. The introduced types are:type 'a gen
: represents a generator for a type.type 'a pbt_test
: represents a test for a type.type 'a pbt_result = Success | Fail of 'a
: represents the result of running a test.

Testing framework: expose functions for contract compilation and origination (!1772 by er433)
Details :
New
Test
type and functionstype michelson_contract
: representing Michelson contracts.Test.compile_contract_from_file : string -> string -> string list -> michelson_contract
Test.compile_contract : ('param * 'storage -> operation list * 'storage) -> michelson_contract
Test.read_contract_from_file : string -> michelson_contract
Test.originate_contract : michelson_contract -> michelson_program -> tez -> address
Test.size : michelson_contract -> int
Breaking changes in
Test
types, now they returnmichelson_contract
instead ofmichelson_program
:Test.originate_from_file : string -> string -> string list -> michelson_program -> tez -> address * michelson_contract int
Test.originate : ('param * 'storage -> operation list * 'storage) -> 'storage -> tez -> (('param, 'storage) typed_address * michelson_contract * int)
Most usages ignore this result, but might break some tests in case they are too annotated.
failwith now accepts arbitrary type as input (!1748 by lesenechal.remi)
Details :
The
failwith
primitive now accepts arbitrary type as input.breaking changes
failwith
is now typed asforall a b . a -> b
, instead of applying an ad-hoc rule givingunit
as a default return type. In general, this will require more type annotations, as in:let toplevel_failwith = failwith "I am failing" (* will not type anymore *)let toplevel_failwith : unit = failwith "I am failing"let f = fun (_ : unit) -> failwith (x + x + String.length y) (* will not type anymore *)let f = fun (_ : unit) : unit -> failwith (x + x + String.length y)Closes #193
Remove deprecated constants (!1711 by er433)
Details :
Deprecated constants
In previous versions of LIGO, warnings were emitted for deprecated constants (e.g.
