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
strings: split_join_trim, templating_min, urlencode_decode
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)
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

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.
