The Standard Library

The standard library is the core selling point for Eryx. Each available library is categorised into one of the following statuses:

Status	Meaning
Complete	The library is complete and fully usable
Mostly complete	The library is mature but not complete, but what is present is usable
Partial	The library is partially complete, but what is present is usable
Unusable	The library is in an early stage of development, and is not expected to work properly
Planned	The library does not exist yet

Not all AST nodes are fully exposed properly. Some bindings missing ↩︎
Currently only supports Windows, and likely has GC-related problems ↩︎
Still lacks some advanced CLI ergonomics, but now supports variadic positionals, multi-value options, mutually exclusive groups, and generated shell completion scripts ↩︎
Missing raw mode, line terminators, streaming ↩︎
No OS signals, no users/groups, no resource limits, no forking ↩︎
No access to permissions, potentially other missing features ↩︎
Module not sufficiently tested to be confidently complete ↩︎
Lacks proxy support ↩︎
Immature implementation lacking many features. Not sufficient tested ↩︎
No sufficient tested. Supports only a limited number of features. Some heuristics likely broken ↩︎
No mTLS support, no ALPN, no cipher suite selection, no OCSP ↩︎
Subset of YAML 1.2 ↩︎
Limited interface for manipulating ZIP files ↩︎
Very patchy hand-written code, lacking almost all important ASN1 features ↩︎
Extensions not fully featured yet, and some inline parsing bugs present ↩︎
Bare-bones wrapper for WebView2 on windows, but no support for other platforms ↩︎
Missing most things that make wrapping a webview useful ↩︎
Missing must image manipulation features ↩︎
