fun> Fun - Standard Library Overview
Overview of the standard library modules under ./lib with one-line summaries.
Table of contents
This page provides a quick orientation to the standard library located under ./lib/.
The stdlib is written in Fun and organized by domain. Below is the current layout with brief notes. Refer to the source for full APIs and examples.
Top-level modules
arrays.fun— helpers for working with array structures.cli.fun— minimal helpers for building CLI tools.hello.fun— simple demonstration helper(s).hex.fun— hexadecimal encode/decode helpers.math.fun— math helpers in Fun.regex.fun— simple regex-related helpers (see alsoregex/).strings.fun— string manipulation utilities.
Packages
crypt/— cryptographic primitives and hashes. See lib/crypt.aes256.funcrc32.fun,crc32c.funmd5.fun,md5_legacy.funripemd160.fun,ripemd160_new_try.funsha1.fun,sha256.fun,sha384.fun,sha512.fun
encoding/— text/binary encodings and conversions. See lib/encoding.base64.fun
io/— input/output utilities and system interfaces. See lib/io.console.fun— console I/O helpersini.fun— INI parse helpersjson.fun— JSON helperspcsc.fun,pcsc2.fun— smart card access (PC/SC)process.fun— spawn and manage subprocessesserial.fun— serial port helperssocket.fun— socket convenience wrappersthread.fun— simple threading utilitiesxml.fun— XML helpers
net/— networking helpers and example HTTP servers. See lib/net.cgi.fun— basic CGI helpershttp_server.fun— blocking HTTP serverhttp_cgi_server.fun— HTTP server that can execute .fun CGI fileshttp_cgi_lib_server.fun— variant of the HTTP CGI server using the stdlib
regex/— regular expression utilities (PCRE2-based when available). See lib/regex.pcre2.fun
ui/— user interface helpers (built if the corresponding extensions are enabled). See lib/ui.notcurses.funtk.fun
utils/— small reusable helpers and functional utilities. See lib/utils.datetime.funmatch.funmath.funoption.funrange.funresult.fun
Note: Availability of some modules can depend on optional extensions selected at build time (see build.md). For instance, regex/pcre2.fun requires PCRE2 support; ui/* depends on chosen UI backends.
