ExamplesA check decides whether a program is called
import { ASSOCIATED_TOKEN_PROGRAM_ADDRESS_BYTES, SYSTEM_PROGRAM_ADDRESS_BYTES, TOKEN_PROGRAM_ADDRESS_BYTES, account, defineTemplate, ensureAssociatedTokenAccount,} from '@jac0xb/ballista';const createIfMissing = defineTemplate({ accounts: { // The programs it calls, pinned to their real addresses. ataProgram: { executable: true, address: ASSOCIATED_TOKEN_PROGRAM_ADDRESS_BYTES, }, tokenProgram: { executable: true, address: TOKEN_PROGRAM_ADDRESS_BYTES, }, systemProgram: { executable: true, address: SYSTEM_PROGRAM_ADDRESS_BYTES, }, // The accounts the caller passes in. mint: { owner: TOKEN_PROGRAM_ADDRESS_BYTES, minDataLength: 82 }, payer: { signer: true, writable: true }, wallet: {}, ata: { writable: true }, }, steps: [ // Calls Create only while the token account is still empty. ensureAssociatedTokenAccount({ associatedTokenProgram: account.fixed('ataProgram'), payer: account.fixed('payer'), associatedTokenAccount: account.fixed('ata'), owner: account.fixed('wallet'), mint: account.fixed('mint'), systemProgram: account.fixed('systemProgram'), tokenProgram: account.fixed('tokenProgram'), }), ],});Case
The account is empty, so the template calls Create.1 call
