This page provides a quick orientation to the standard library located under https://git.xw3.org/fun/fun/src/branch/main/lib{:class="git"}.

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 also regex/).
• strings.fun - string manipulation utilities.

Packages

• crypt/ - cryptographic primitives and hashes. See https://git.xw3.org/fun/fun/src/branch/main/lib/crypt/{:class="git"}.

  • aes256.fun
  • crc32.fun, crc32c.fun
  • md5.fun, md5_legacy.fun
  • ripemd160.fun, ripemd160_new_try.fun
  • sha1.fun, sha256.fun, sha384.fun, sha512.fun

• encoding/ — text/binary encodings and conversions. See https://git.xw3.org/fun/fun/src/branch/main/lib/encoding/{:class="git"}.

  • base64.fun

• io/ — input/output utilities and system interfaces. See https://git.xw3.org/fun/fun/src/branch/main/lib/io/{:class="git"}.

  • socket.fun - socket convenience wrappers
  • thread.fun - simple threading utilities
  • xml.fun - XML helpers

• net/ - networking helpers and example HTTP servers. See https://git.xw3.org/fun/fun/src/branch/main/lib/net/{:class="git"}.

  • cgi.fun - basic CGI helpers
  • http_server.fun - blocking HTTP server
  • http_cgi_server.fun - HTTP server that can execute .fun CGI files
  • http_cgi_lib_server.fun - variant of the HTTP CGI server using the stdlib

• regex/ - regular expression utilities (PCRE2-based when available). See https://git.xw3.org/fun/fun/src/branch/main/lib/regex/{:class="git"}.

  • pcre2.fun

• utils/ - small reusable helpers and functional utilities. See https://git.xw3.org/fun/fun/src/branch/main/lib/utils/{:class="git"}.

  • datetime.fun
  • match.fun
  • math.fun
  • option.fun
  • range.fun
  • result.fun

Note: Availability of some modules can depend on optional extensions selected at build time (see Build). For instance, regex/pcre2.fun requires PCRE2 support; ui/* depends on chosen UI backends.

Using modules

#include <strings.fun>

s = trim("  hello  ")
print(s)
