Fun Examples

This directory contains small, pure Fun examples organized by topic.

How to run:

• Build the interpreter once: cmake --build ./build_debug --target fun
• Execute an example: ./build_debug/fun ./examples/<path>.fun
• For CGI examples under examples/data/htdocs, start one of the blocking HTTP servers from examples/blocking/ and visit the URL noted in the file headers.

Categories:

• basics: hello_world, fizzbuzz, fibonacci, collections, boolean_decl, booleans, builtins_conversions
• arrays: arrays, arrays_advanced, arrays_iter
• strings: split_join_trim, templating_min, urlencode_decode, base64_demo
• io: read_write_file, csv_reader (uses examples/io/sample.csv), word_count
• algos: sort_and_search, deduplicate, stack_queue
• cli: env_echo, args_parse (parse ARGS env), cli_parse_example
• net: tcp_echo_server, tcp_echo_client, http_static_server (blocking)
• data/htdocs (CGI): hello.fun, info.fun, counter.fun, form_post.fun, redirect.fun, json_like_api.fun
• compose: run_other_fun, pipeline
• patterns: assert_like, logging_min
• snippets: escape_html_demo, maps_iterate, include_namespace

Notes:

• Scripts that start servers (tcp_echo_server, http_static_server, http_server_cgi*.fun) are blocking; run them in a separate terminal.
• Some examples rely on stdlib includes; if needed, set FUN_LIB_DIR=./lib before running.
