I've been looking at using libspng to replace libpng in [NetSurf](https://www.netsurf-browser.org/) and I was about to request progressive decoding when I found this. At the moment we use libpng's `png_process_data()`....

Hi @dawoun, Thank you for your interest in LibCYAML. I have a plan for default values where the default value will always be provided via a pointer. This will allow...

Can you give me an example use-case to think about? Why would this be more useful than simply filling out your data structures before saving, or annotating them with extra...

Would support for unions handle this use case? ```c struct my_thing { enum my_type type; union my_data data; }; ```

Agreed, this would we useful. It's something I've thought of, but never implemented because I've not had a need for it so far. I'll try to have a look into...

I've had a think about it. Basically, I'd add a `void *def_val` member to the `struct cyaml_schema_value`. So the value schema could provide a pointer to a default value, or...

`cyaml__read_bool` isn't called unless there is an actual value in the YAML to decode. The bit representation for any unset optional field is always `0`. So for numbers it's zero,...
