Package: tackle-box
tackle-boxDocumentationDiscordPyPIBSD LicenseTackle-box is an experimental DSL for building modular code generators and declarative CLIs. Built as a fork ofcookiecutter, it can make any config file into a CLI with both strong and weakly typed programmable flow control common to a general purpose programming language. Basically you can write a fully functional Turing-complete program out of a config file. It's wild.With tackle-box, you can build:Modular code generators / repo scaffolding tools that can be updated over timeDeclarative makefile alternatives for advanced toolchain managementInteractive glue code for infrastructure-as-code deployment strategiesGeneric utilities like SSH registries and dotfile managersCombinations of all of the above and anything else you can think ofIf this project gets enough adoption / stars, it will be re-written in a compiled language. Its current goal is defining the syntax which should remain stable after a rewrite.FeaturesMakes arbitrary yaml / json / tomldynamicEmbed loops, conditionals, and other custom logicSelf documenting CLI to call logicShips with a collection of over100 hooksthat act like plugins within your config filePrompt user for inputsGenerate code from templatesRead and writeyaml/toml/jsonfilesMake http callsRun arbitrary system commandsManipulate the contextRun other tackle filesModular design allows creating / importing new hooks easySupports bothpythonanddeclarativehooks which can be imported / called / defined in-line or within jinja templatesInstallNote: tackle can install dependencies on its own.

This is the default hook

options:
    --target [str] The thing to say hello to
methods:
    greeting-method     A method that greets
    greeter     A reusable greeter objectHooks can be imported, linked, and/or combined creating a web of CLIs.Use CasesCode GenerationWIP TutorialsDeclarative UtilitiesInfrastructure-as-Code ManagementKubernetes Manifest ManagementToolchain ManagementTopicsWriting Tackle FilesCreating ProvidersPython HooksDeclarative HooksBlocksandFlow ControlMemory ManagementSpecial VariablesDeclarative CLIsContributingContributions are welcome but please be advised of the following notes.This project usesconventional commitswhich generates thechangelogwithrelease-please-actionin thereleaseCI workflow. If commits have been made outside of this convention they will be squashed accordingly.For making changes to providers, please include test coverage using the existing fixtures and patterns from prior tests or communicate any suggestions that deviate from this style. Tests should be runnable from the test's directory and viamake test.For making changes to the core parser, please create a proposal first outlining your suggestions with examples before spending time working on code.It is very easy to create new providers / hooks with tackle-box. Over time, it will adopt the same import pattern of what Ansible does where all provider / hooks (modules) are stored in version controlled locations. In the meantime, please feel free to contribute to this repository for hooks that have general applicability or create your own hooks in other repositories that are more bespoke / opinionated in nature.Code of ConductEveryone interacting in the tackle-box project's codebases, issue trackers, chat rooms, and mailing lists is expected to follow thePyPA Code of Conduct.CreditSpecial thanks to thecookiecuttercommunity for laying the basis for this project.
