xnhttpd

xnhttpd

• A simple CGI server for testing, as an alternative to AN HTTPD
• Markdown viewer
• Experimental Lua application server

xnhttpd {OPTIONS} [SETTING-JSON-PATH]

Options

• -C string Working directory

• -hardwrap Enable hard wrap in *.md

• -html Enable raw HTML in *.md

• -index string Default page when the URL points to a directory (default: "index.html,README.md,INDEX.md")

• -p uint Port number (default: 8000)

• -perl Enable Perl as a handler for *.pl

This starts a local server on localhost:8000 and allows CGI scripts to run from the current directory.

Example Setting JSON

{
  "handler": {
    ".pl": "c:/Program Files/Git/usr/bin/perl.exe"
  },
  "markdown": {
    "html": true,
    "hardwrap": true
  }
}

To try the sample wiki engine, open http://127.0.0.1:8000/wiki.pl in your browser.

Features

Markdown Viewer

When a requested URL ends with .md and the file exists, the embedded Markdown viewer (goldmark) renders it.

If "html": true is set in the JSON config, raw HTML tags are allowed in Markdown files.

Lua Application Server (Experimental)

When a requested URL ends with .lua and the file exists, the embedded Lua interpreter (GopherLua) runs the script.

Example:

print("<html><body>")
print("<h1>Embedded Lua Test</h1>")

for _, key in pairs{
  "QUERY_STRING", "CONTENT_LENGTH", "REQUEST_METHOD",
  "HTTP_COOKIE", "HTTP_USER_AGENT", "SCRIPT_NAME", "REMOTE_ADDR"
} do
  print(string.format("<div>%s=%s</div>", esc(key), esc(_G[key])))
end

print("<hr />")

print(string.format("<div>a=%s</div>", esc(get("a"))))

print(string.format([[
<form action="%s" method="post">
  <div>New `a` value</div>
  <div>
    <input type="text" name="a" value="%s" />
    <input type="submit" />
  </div>
</form>
]], esc(SCRIPT_NAME), esc(get("a"))))

local counter = cookie("counter")
if counter and counter.value then
  counter = { value = tonumber(counter.value) + 1 }
else
  counter = { value = 1 }
end
setcookie("counter", counter.value)

print("counter=" .. counter.value)
print("</body></html>")
