EdjCase.ICP.ClientGenerator 2.2.4

Client Generator

• Library of generating C# client code from *.did files
• Nuget: EdjCase.ICP.ClientGenerator

Usage (dotnet tool)

Install with dotnet tools

dotnet tool install -g EdjCase.ICP.ClientGenerator

Run tool

(First run only) Initialize config file and update generated file

candid-client-generator init ./

Creates candid-client.toml file to update in specified directory

Example:

namespace = "My.Namespace" # Base namespace used for generated files
output-directory = "./Clients" # Directory to put clients. Each client will get its own sub folder based on its name. If not specified, will use current directory
no-folders = false # If true, will put all the files in a single directory

[[clients]]
name = "Dex" # Used for the name of the folder and client class
type = "file" # Create client based on service definition file
file-path = "./ServiceDefinitionFiles/Dex.did" # Service definition file path
output-directory = "./Clients/D" # Override base output directory, but this specifies the subfolder
no-folders = false # If true, will put all the files in a single directory


# Can specify multiple clients by defining another
[[clients]]
name = "Governance"
type = "canister" # Create client based on canister
canister-id = "rrkah-fqaaa-aaaaa-aaaaq-cai" # Canister to create client for

Generate clients

candid-client-generator ./

or

candid-client-generator gen ./

Config file options

Top Level:

• namespace - (Text) REQUIRED. The base namespace used in all C# files generated. Files generated in a sub-folder will have a more specific namespace to match. This namespace can be overidden per client.
• output-directory - (Text) OPTIONAL. Directory to put all generated files. Each client will have a sub-folder within the output directory that will match the client name. If not specified, the working directory will be used
• no-folders - (Bool) OPTIONAL. If true, no sub-folders will be generated for the clients or the models within the clients. All generated files will be in a flat structure. Defaults to false
• url - (Text) OPTIONAL. Sets the boundry node url to use for making calls to canisters on the IC. Can be set to a local developer instance/localhost. Defaults to 'https://ic0.app/'. This setting is only useful for clients of generation type canister
• feature-nullable - (Bool) Optional. Sets whether to use the C# nullable feature when generating the client (like object?). Defaults to true
• keep-candid-case - (Bool) Optional. If true, the names of properties and methods will keep the raw candid name. Otherwise they will be converted to something prettier. Defaults to false

Client Level:

• name - (Text) REQUIRED. The name of the sub-folder put the client files and the prefix to the client class name.
• type - (Text) REQUIRED. An enum value to indicate what type of client generation method to use. Each enum value also has associated configuration settings. Options:
  • file - Will create a client based on a service definition file (*.did)
    • file-path - (Text) REQUIRED. The file path to the *.did file to generate from
  • canister - Creates a client based on a canister id
    • cansiter-id - (Text) REQUIRED. The principal id of the canister to generate a client for
• output-directory - (Text) OPTIONAL. Directory to put all generated client files. Overrides the top level output-directory. NOTE: this does not create a sub-folder based on the client name like the top level output-directory does
• no-folders - (Bool) OPTIONAL. If true, no sub-folders will be generated for the client. All generated files will be in a flat structure. Defaults to false. Overrides the top level no-folders
• feature-nullable - (Bool) Optional. Sets whether to use the C# nullable feature when generating the client (like object?). Defaults to true. Overrides the top level feature-nullable
• keep-candid-case - (Bool) Optional. If true, the names of properties and methods will keep the raw candid name. Otherwise they will be converted to something prettier. Defaults to false. Overrides the top level keep-candid-case
