yaml-rust VS yaml-cpp

Either https://github.com/chyh1990/yaml-rust or https://github.com/dtolnay/serde-yaml for parsing the YAML config file that markdownlint uses

Here's the Rust code so far -- the commented portions are my intent via pseudocode. This is part of an implementation where there's a _yaml_hash member that points to yaml_rust's underlying LinkedHashMap. (Also using anyhow's bail! and Result.)

The first thing I did was to find the crate yaml-rust and it seems it isn't really maintained anymore. It has not been updated in a year and there's a lot of PR's and unresolved issues, the CI is broken... So here is my open ended question.

Currently, my main concern with YAML is that, by the spec, comments are not attached to a particular node (see https://yaml.org/spec/1.2/spec.html#id2767100). As a result, a lot of YAML parsers (like https://github.com/yaml/libyaml and https://github.com/chyh1990/yaml-rust) only filter out the comments during the parsing phase. This makes it less than ideal for a use-case where the configuration file is expected to be modified by both programs and humans.

TOML makes it more trivial to associate comments with a node. This is mainly because the language is simpler though, as the spec is not explicit about that (https://github.com/chyh1990/yaml-rust).

As you can see, I'm trying to coerce some YAML::Node to get some unknown type:

Some context, In my day job, I'm working on a custom format that is based on yaml but extends it. We're still using C++, so we the used yaml-cpp as a base for our parser and it was great for that purpose. laying with rust on Advent of Code lately I also got sent back to reality... Not having rust enums, match, great string handling, iterators when working with my AST was hard. So I wanted to try to implement the same parser in Rust as an example to my teammates of how great rust can be.

yaml-cpp

Hi, this is a library (https://github.com/jbeder/yaml-cpp), I tried to add it but unfortunately I can't, and I can't find any instructions.

cmake_minimum_required(VERSION 3.0.0) project(cmaketest VERSION 0.1.0) include(CTest) enable_testing() include(ExternalProject) ExternalProject_Add(yaml PREFIX 3rd_party GIT_REPOSITORY https://github.com/jbeder/yaml-cpp/ INSTALL_COMMAND "" ) add_executable(cmaketest main.cpp) set(CPACK_PROJECT_NAME ${PROJECT_NAME}) set(CPACK_PROJECT_VERSION ${PROJECT_VERSION}) include(CPack)

I've found is yaml-cpp. The API seems fine

If you want a file format that has more readability, YAML is probably your best bet.

Can this not be parsed as YAML? (https://github.com/jbeder/yaml-cpp)
