=== API

==== Instantiation
This module exposes a single functor, {{awful main}}, which is instantiated to
produce a main module that can be compiled into a static executable.

This can be done using two separate modules:

<enscript highlight="scheme"> 
; site.scm
(module site (run)
  (import scheme awful (chicken base) (chicken format))
  (define (run args)
    (let ((name (member "name" args)))
      (unless name (error "Required argument: name"))
      (define-page
        (main-page-path)
        (lambda ()
          (set-page-title! "awful-main example")
          (sprintf "Hi, ~A, I'm using awful-main" (cadr name)))))))

[lang:scheme]

; main.scm
(import (awful main) site)
(module main = ((awful main) site))
</enscript>

... or with a single in-line functor instantiation:

<enscript highlight="scheme"> 
; main.scm
(import (awful main))
(module main = (awful main)
  (import scheme awful (chicken base) (chicken format))
  (define (run args)
    (let ((name (member "name" args)))
      (unless name (error "Required argument: name"))
      (define-page
        (main-page-path)
        (lambda ()
          (set-page-title! "awful-main example")
          (sprintf "Hi, ~A, I'm using awful-main" (cadr name)))))))
</enscript>

A static executable implementing the website can then be compiled, e.g.,
via the command line {{csm -static -program main}}.


==== Runtime
The generated {{main}} program can be invoked with the following arguments, where
{{<root>}} is the directory containing the {{main}} program.

<enscript highlight="shell"> 
-user       user          User to run the website as
-addr       <ip-addr>     Bind to <ip-addr>                   default: 127.0.0.1
-port       <port-num>    Bind to <port-num>                  default: 8080
-access-log <path>        Enable access log to <path>         default: <root>/access.log
-debug-log  <path>        Enable debug log to <path>          default: disabled
-error-log  <path>        Enable error log to <path>          default: <root>/error.log
-web-root   <path>        Path to the web-root                default: <root>/static
-dev                      Start awful in dev mode             default: false
-args                     Pass additional arguments to `run`
</enscript>

If {{-args}} is specified, any additional arguments present on the command line
are passed to the {{run}} function in the implementation. Example:

<enscript highlight="shell"> 
./main --port=9092 --web-root=./static --args name Joe
</enscript>

For a minimal working example, see the [[https://code.ptrcrt.ch/awful-main/dir?ci=trunk&name=example|example]] directory in the source code
repository.
