To try it out yourself, run make monogen \
&& cd .. \
&& ./monomer/bin/monogen \
&& cd testapp \
&& ../monomer/monogen/monogen.sh \
&& ./testappd monomer start --minimum-gas-prices 0.01stakeTwo follow-ups are planned:
The idea is that we can instruct users to run go run github.com/polymerdao/monomer/cmd/monogen@latestand automatically paste |

I'll fix the lints tomorrow. This is ready for review otherwise. This is a monolithic change; it will not be useful to review commit-by-commit. |

monogen/monogen.sh (1)
1-40: Great work on automating the initialization and setup process for a Cosmos SDK-based application!The script is well-structured, follows best practices, and provides useful comments and documentation. It automates the initialization and setup process for a Cosmos SDK-based application, which is a good practice and will save time and reduce errors.
As a suggestion for improvement, consider adding a help message or usage instructions at the beginning of the script to provide more information about what the script does and how to use it. This will make it easier for other developers to understand and use the script.
monogen/monogen.go (2)
19-20: Address the TODO comment.The TODO comment indicates that the function should handle the case when the directory already exists. Please ensure that this case is handled appropriately to avoid overwriting existing files or throwing an error.
Do you want me to generate the code to handle this case or open a GitHub issue to track this task?
18-89: Consider decomposing the function into smaller functions.The
Generatefunction is quite large and performs several distinct tasks. Consider decomposing it into smaller functions for better readability and maintainability. For example, you could extract the code for applying modifications into a separate function.

monogen/monogen.sh (4)
1-4: LGTM!The shebang line is correct, and the
set -ecommand is a good practice to stop the script execution if any command fails.
6-10: LGTM!The code segment correctly checks the Go version and sets the
ldflagsvariable accordingly. Thego buildcommand is used to build the binary with the correct flags.
12-34: LGTM!The code segment correctly initializes the application's config and data directories, creates a dummy account, funds it at genesis, and facilitates the creation of a genesis transaction for the dummy account to self-delegate as a validator. Finally, it collects the generated transactions into the genesis file.
36-40: LGTM!The comment is informative and provides a useful command to start the application with configurable minimum gas prices.
monogen/monogen_test.go (3)
16-62: Comprehensive and well-structured test formonogen.Generate.The test function
TestGenerateis well-designed and covers the essential aspects of themonogen.Generatefunction. It follows a clear and logical flow, setting up the environment, executing the generation script, starting the application, and performing a connectivity check with the blockchain.The test takes appropriate measures to ensure that it does not interfere with the user's environment by using a temporary directory and custom home environment variable. It effectively validates the integration of the
monogenfunctionality with the CometBFT client by verifying the connectivity and retrieving the block information.The test uses appropriate assertions to verify the expected behavior and handles the cleanup of the started application using
deferstatements. The use of a customlogWriterto capture the output of the executed commands is a nice touch for debugging purposes.Overall, this test provides confidence in the correctness of the
monogen.Generatefunction and its integration with the CometBFT client.
64-64: Clear and concise type alias for logging functionality.The
logWritertype alias provides a clear and concise way to define the logging functionality used in the test function. By using a function type that takes a variadic parameter of typeany, it can be easily used with thet.Logfunction to capture the output of the executed commands.The type alias improves the readability of the code and encapsulates the logging functionality in a meaningful way.
66-69: Effective implementation of theio.Writerinterface for logging.The
Writemethod on thelogWritertype correctly implements theio.Writerinterface, allowing it to be used for capturing the output of the executed commands in the test function.By logging the string representation of the input byte slice using the
logWriterfunction, it effectively captures the output. The method adheres to theio.Writerinterface contract by returning the length of the input byte slice and anilerror.This implementation enables seamless integration with the
cmd.Stdoutandcmd.Stderrfields, facilitating the capture of command output for debugging purposes.Makefile (4)
5-5: LGTM!The
BINvariable is defined correctly using the conditional assignment operator, allowing the user to override the default value if needed. The variable is used appropriately in themonogentarget to specify the output directory for the binary.
13-13: LGTM!The
monogentarget is declared correctly as a phony target using the.PHONYdirective. This ensures that the target is always executed, regardless of the existence of a file namedmonogenin the directory.
14-15: LGTM!The
monogentarget is defined correctly to compile the Go program located in./monogen/cmdusing thego buildcommand. The-oflag is used appropriately to specify the output directory and binary name using theBINvariable.
94-94: LGTM!The
cleantarget is updated correctly to remove the$(BIN)directory if it exists. Theifstatement is used appropriately to check for the directory's existence before attempting to remove it recursively using therm -rcommand. This ensures effective cleanup of the build artifacts.monogen/monogen.go (4)
91-158: LGTM!The
addRollupModulefunction correctly adds the rollup module to the application. The changes are well-structured and follow best practices.
160-211: LGTM!The
removeConsensusModulefunction correctly removes the consensus module from the application. The changes are well-structured and follow best practices.
213-242: LGTM!The
addMonomerCommandfunction correctly adds the Monomer command to the application's command structure. The changes are well-structured and follow best practices.
244-263: LGTM!The
addReplaceDirectivesfunction correctly adds the replace directives to the go.mod file. The changes are well-structured and follow best practices.go.mod (18)
