v0.2.0

Happy to announce our v0.2.0 of Código's AI generator

We have heard your feedback, and have adjusted accordingly. This release focuses on increasing the CIDL usability, reducing verbosity, expanding the supported use cases, and setting the basis for future new cases i.e. pass data structure as inputs, enums, and more.

Until we hit GA, the releases will not be backward compatible. Thus, this release contains breaking changes.

Highlights

Added .cidl extension

Now CIDL files are defined with the .cidl extension, this is the basis for adding support to our IDE assistance. The .yaml and .yml files are still supported.

Changed how solana accounts are defined

Previously solana accounts were inferred based on (custom-defined) types, each custom data type when targeting the solana blockchain will be generated as an account. If the type defined the solana extension with seeds, this type will be generated as a PDA account.

Now solana accounts are defined as sol:account<T, K> where T is an optional custom-defined type (also known as layout) and K is an optional solana seeds definition (see next two sections). Now with this way of specifying accounts, we can define PDA accounts without layout by specifying the underscore _ to the T of sol:account<T, K>.

Example

solana:
  seeds:
    MySeedName:
      items:
        - name: static
        - name: dynamic
          type: u8
methods:
  - name: simple_method
     inputs:
       - name: pda_account_without_layout
         type: sol:account<_, seeds.MySeedName>

Added solana extension to the root of the CIDL

This new object can optionally be defined at the root of the CIL. Through this object, we can define seeds.

solana:
  seeds:
    SeedName:
       # ...

Changed how solana seeds are defined

Previously we defined seeds at the (custom-defined) type level. This had several issues i.e. we had to duplicate the entire data structure to have 2 or more PDA accounts with the same layout, it was a blocker to allow data structure as input, and didn't allow PDA accounts without layout.

Now at the solana root extension within the seeds, we can define seeds definitions, these definitions can then be referenced when defining a solana account.

Example:

solana:
  seeds:
    MySeedName:
      items:
        - name: static
        - name: dynamic
          type: u8
types:
  MyType:
    fields:
      - name: state
        type: u8
methods:
  - name: simple_method
     inputs:
       - name: pda_account
         type: sol:account<MyType, seeds.MySeedName>

Made it clear when a value is assigned to an attribute

In multiple attributes like the cap, we used to assign a value using the colon i.e. cap:36. This was confusing since we used the colon to prefix extended data types, and for some users, it wasn't obvious what was happening. We have replaced the colon with the equal sign =, now for attributes that require or can have a value, will be assigned with the equal sign i.e cap=36

Removed solana extension from fields

Previously, the only possible attribute for a field was the cap, this attribute only applied to string and rs:vec<t>. It was cumbersome to be defining the solana extension and an indentation level to define the cap attribute. Now the attribute property is at the field level.

Example:

fields:
  - name: my_field_name
    type: string
    attributes: [ cap=36 ]

Removed solana extension from input

One of the more verbose places in the CIDL was the solana extension for input. We have remove the solana input's extension! Now each property that was possible to define in the extension can be defined as an attribute of the input; now, the attribute property is at the input's level.

Example:

methods:
  - name: simple_method
    inputs:
      - name: account
        type: sol:account
        attributes: [ sol:init ]

Changed how inputs can be linked to PDAs' seed

Previously to link an input or a signer, to a PDA seed we had to define the solana extension and within the solana extension define the seed objects and map it based on key-value, where the key of the object was the name of the seed and the value was the name of an input, this was confusing and could cause error easily.

Now when we specify the seed definition to an account in parentheses we can link the input or signer to the seed in a parameter name style.

solana:
  seeds:
    MySeedName:
      items:
        - name: owner
          type: sol:pubkey
        - name: id
          type: u64
methods:
  - name: simple_method
     signers:
        - name: delegate
          type: sol:account
     inputs:
       - name: pda_account
         type: sol:account<MyType, seeds.MySeedName(id=index, owner=delegate)>
       - name: index
         type: u64

Removed solana extension from types

Previously we were able to define the solana extension at the custom-defined type level. Through this extension, we were able to define the owner of the account, if the type was compressed, and the definition of the seed.

Now, this extension no longer exists. Seeds are defined as described above, the owner is defined with the sol:owner=SomePubkey attribute, and the type to compress is defined at the method's solana extension (see next section).

Restructure solana method extension

Previously through the solana method's extension, we were able to define the signers, this has been moved to the method's level (see next section).

Now at the solana method's extension, we can define the types that we want to compress with solana state compression. Thus, also modifying how to specify a type was determined to be compressed.

Example:

types:
  Article:
    fields:
      - name: title
         type: string
         attributes: [ cap=96 ]
methods:
  - name: simple_method
    solana:
      compress:
        - type: Article
          mode: append

Change how signers are defined

Previously we defined the signers at the solana method's extension and linked an input to a signer by name.

Now the signers have been moved to the method's level. And the linkage from a signer to an input has been redefined with an explicit property name input.

Example:

methods:
  - name: simple_method
     signers:
       - name: fee_payer
          type: sol:account
       - input: delegate
     inputs:
       - name: delegate
         type: sol:account

Updated generated Anchor program to v0.29.0

We have made a lot of improvements to our Anchor-generated code. Have improved the generated code, fixed a lot of bugs, expanded supported use cases to the native level (SPL and State compression are still in the work), and generated Anchor with the latest version v0.29.0 with multiple files template.

Improved error messaging

Previously, the validation error messages were obscure, not friendly, and non-informative.

Example v0.1.0 (Previous version):

- name: fee
  type: 

Error message:

unmarshal error the data type u9 is not a primitive, extended, user-defined or imported type.

Example v0.2.0 (Current version):

- name: fee
  type: 

Error message:

Trace: /path/yo/your/file.cidl:43:15
Code: C-TYPE0012
SyntaxError: The data type "u9" is not supported for type's fields'

We can notice that the error message contains a code. From now on, all error messages will be coded and will be documented in our https://docs.codigo.ai

General

• Change rs:vec<t> for array<t>
• Change rs:option<t> for ? operator. The operator must be specified as a suffix to the type
• Added u64 and i64 support to seeds' type
• Swap rent-payer property from the input's solana extension for the sol:rent-payer= attribute
• Swap rent-receiver property from the input's solana extension for the sol:rent-receiver= attribute

v0.1.0

What's new

General

• CIDL imports. Compose your CIDLs with other CIDLs implemented by Código or the Community.
• Restructure the generated native program and client projects for better readability and maintainability.
• Improve the Código CLI
  • Added flags to overwrite the default location for the generated program and program client
  • Added flags only to generate the program or the client
• Added the Anchor CLI to Código Studio
• Downloadable CLI. Now, you can download Código CLI to work from your local environment.

Solana

• Anchor support was one of the most requested features during the private beta. We are glad to inform you that now you can generate 100% of the boilerplate code for the program and client libraries using the Anchor framework.
• Expanded the supported use cases by adding support for cross-program invocation (CPI) of depth-1.
• Solana has done a fantastic job helping the community reduce blockchain fees; thus, this release introduces state compression support.
