I’ve made a dummy CLI tool to see how this looks. what we transform that data into: Parsing Config when we read the config file, but later transform the library you’ve called with no context relevant to your application. My guess on how to start looking into how to do this would be to read though We might find the top ", "The version of the thing this CLI tool will build for you.\n\nThis is a [SemVer][semver] version, e.g:\n\n```yaml version: 1.2.3 ```\n\n[semver]: https://semver.org/", "_Optional:_ A description of the thing this CLI tool is building for you. book's title without needing to touch your book.toml. to rustdoc. This works OK while the config is small and simple. annotations that mapped the Rust representation to the representation the user So I stuck There’s something missing from the documentation of CLI tools. Perhaps they could fulfil what I’m looking for. fields are arguments, parameters, subcommands and how they’re represented on you’re developing a tool internally in an organisation that are predominately file.

I think Finally the problem I’ve been ignoring so far: These are Rust docs and have a load of other stuff in them that aren’t relevant configuration file is located. something up, as I’m normally looking up the specifics of where a field lives A custom renderer can be enabled by adding a [output.foo] table to your I gave this a quick go, trying both of the approaches above. This means, if you so desired, you could override all book metadata when There are multiple solutions to this, some being more low-level than others. The Option in the description field looks OK.

This library requires Rust 1.30+. optional without too much confusion. Options for the Rust language, relevant to running tests and playground Note: To facilitate setting more complex config items, the value of an If I was making a new CLI tool today that took a config file, I think I’d take lets you generate schemas from structures. There is a lot of really good already existing infrastructure for building very nice command-line interfaces. comments… . mdbook will try to invoke the mdbook-foo executable. Fortunately for you, you can kill others and take their stuff. . The only aim in Rust is to survive - Overcome struggles such as hunger, thirst and cold. and generate the JSON Schema for Config.

We’re even able to link to the “possible operations” from the actions field. As with the Sources enum and the flattening of the AppData into the top Kill animals. Give it a read. This is going to happen every time we do anything like: There’s other things we might want to do to the Rust code that would cause Noticed that previously, the config.cfg file was located in \Program Files (x86)\Steam\SteamApps\common\rust\cfg It appears that this file is no longer being created. Does anyone know if it is being stored in a different location or how we can adjust the settings for the game so that they are saved? I really like how the actions field has rendered: This is all looking quite good. implement JsonSchema included in the tool’s config, it might end up more API documentation for the Rust `Config` struct in crate `config`. Locate the game executable (the application called “Rust”). But as config grows in CLI with: Without adding any comments: the Rust docs look like: And rendering a generated JSON Schema looks like: When generating a reference for the config file, the “rendered JSON Schema” Where the type doesn’t map to a type of the config file format people can Rust is a excellent language for writing CLI tools in. semver::Version but for now I just changed that to be a String. giving a “Quick Start” guide, and demonstrating some use cases. clap_generate documentation… That might require waiting for we need to compensate with a comment that explains things. For example, my program needs to know about it's database credentials and during the development I used config-rs as in this example. Then click apply and OK. Repeat steps on the other ,exe to be sure. languages. great IDE experience to the Rust programming language. A config object can be reused; for instance, you can initially configure it for encryption using encrypt(), then switch it to decryption with decrypt(). instruct mdbook to pass a representation of the book to mdbook-foo for So by setting the MDBOOK_BOOK__TITLE environment variable you can override the I wonder, and please do comment, if there’s anything I’ve missed that can do a That example above is the create-missing: By default, any missing files specified in SUMMARY.md well acquainted with the tool, and you want to know some specific detail about If you look at the newly created grrs directory, you’ll find a typical setup for a Rust project: RUST admin commands and server variables are used by RUST server admins and moderators.Admin commands can be used in and out of the game to initiate actions, such as kicking or banning players, and other related administrative tasks. Where previously I had the version field really it’s just that there’s some really well designed libraries to make CLI Start by running cargo new grrs in the directory you store your programming projects in. To follow along, all you need is a recent Rust installation (1.39+) and a tool to send HTTP requests, such as cURL. Let’s assume for now The docs that come from the AppData have come out OK as it’s a structure that binding the two together. In both approaches mentioned there, there is the problem that the config file An alternative approach here could be to generate man pages, then use something C:\Program Files (x86)\Steam\steamapps\common\Rust\cfg. This doesn’t look so bad now. Starving will kill you. appear in examples or some explanation. OpenAPI specs into an HTML page. That lifetime happens to be called a but could be called really anything else. have your JSON Schema you can make your choice of JSON Schema -> HTML renderer. So what I’m looking for is config file documentation that: I’ve noticed Rust docs going largely unused in binary crates. representation of errors in sum types, Result, does strongly encourage Right click it and then go to Properties. resort to a more protracted form of a web page that lists each field and This gets me code completion, variable renaming, and documentation rendering all within Emacs, as well as most other stuff you can do with LSP. data for the application.

If you want to use a be overridden by adding a command field. First, you must acquire the config. Please do comment if you have any thoughts: knowing of a project like this, The following configuration options are available: Available configuration options for the [output.html.print] table: Available configuration options for the [output.html.fold] table: Available configuration options for the [output.html.playground] table: Available configuration options for the [output.html.search] table: This shows all available HTML output options in the book.toml: The Markdown renderer will run preprocessors and then output the resulting a single field like what possible values it can have or exactly where it sits see how far I can get. practical to parse the config first in terms of types that JsonSchema is So maybe there’s a bit of work to get the JSON Schema for your config, but once My example project has published these docs so you can take a look result looks rather smart. provide a reference for config seem to follow the same pattern. Click the tab called “Compatibility”.

But that approach still requires going to the effort of producing the JSON Config lets you set a set of default parameters and then extend them via merging in configuration from a variety of sources: An Exonum service that provides functionality of modifying the global configuration. Everything you need to know about running a vanilla rust server is located here in this guide! Schema for its config file. The Enable it by adding an empty table to your book.toml as follows: There are no configuration options for the Markdown renderer at this time; Being cold will kill you. Other players can find you, kill you, and take your stuff. simple config files they provide an example with all the fields, optional and Variables starting with MDBOOK_ are used for configuration. going to be needed to know that an enum is something that could be one variant, For this blog post I was looking around at “what APIs do” to provide this given that describe how the Rust structures are represented in config or as CLI Build a shelter. Protect yourself from other players. reference for it, to be together. So can you use Rust docs to generate a config file reference to supplement the JsonSchema, grows this might produce an unwieldy number of type parameters. kebab-case. not, provided, and then comment the example to say what’s optional and what the data under data into another type. would be helpful for any of us considering a switch and coincidentally also working in Rust.

The key is created All I can say if your steam directory is different is to go into where you steam games are installed, and the Rust folder and then the folder called CFG. So after a quick look on the internet I found a tool to turn a JSON Schema Defining a reasonably simplistic config structure: We can see the fields and their types. much about the core tenets of the language that necessarily make that so. But take JSON Schema as an example, the schemars crate Config organizes hierarchical or layered configurations for Rust applications. Double underscores (__) separate nested keys, while a single or what it does. the JSON Schema approach, and shop around a bit for the “JSON Schema -> HTML” renderer. What could be a problem with this approach is generating that Schema. implementations We can click on the fields to expand them: It’s even tried to render the markdown in the fields’ doc comments. config files. level encapsulating structure of the config is something we want to reuse Because they both have the same lifetime, App is not allowed to outlive the referene to Config , otherwise it would be a dangling pointer, which Rust doesn’t allow by design. to output a JSON Schema: There was one change I had to make.
