### MODULE

httpd_conf

### MODULE SUMMARY

Configuration utility functions to be used by the Erlang Webserver API programmer.

### DESCRIPTION

This module provides the Erlang Webserver API programmer with utility functions for adding run-time configuration directives.

### EXPORTS

`check_enum(EnumString,ValidEnumStrings) -> Result`

Types:

`EnumString = string()`
`ValidEnumStrings = [string()]`
`Result = {ok,atom()} | {error,not_valid}`

`check_enum/2` checks if `EnumString` is a valid enumeration of `ValidEnumStrings` in which case it is returned as an atom.

`clean(String) -> Stripped`

Types:

`String = Stripped = string()`

`clean/1` removes leading and/or trailing white spaces from `String`.

`custom_clean(String,Before,After) -> Stripped`

Types:

`Before = After = regexp()`
`String = Stripped = string()`

`custom_clean/3` removes leading and/or trailing white spaces and custom characters from `String`. `Before` and `After` are regular expressions, as defined in `regexp(3)`, describing the custom characters.

`is_directory(FilePath) -> Result`

Types:

`FilePath = string()`
`Result = {ok,Directory} | {error,Reason}`
`Directory = string()`
`Reason = string() | enoent | eaccess | enotdir | FileInfo`
`FileInfo = File info record`

`is_directory/1` checks if `FilePath` is a directory in which case it is returned. Please read `file(3)` for a description of `enoent`, `eaccess` and `enotdir`. The definition of the file info record can be found by including `file.hrl` from the kernel application, see file(3).

`is_file(FilePath) -> Result`

Types:

`FilePath = string()`
`Result = {ok,File} | {error,Reason}`
`File = string()`
`Reason = string() | enoent | eaccess | enotdir | FileInfo`
`FileInfo = File info record`

`is_file/1` checks if `FilePath` is a regular file in which case it is returned. Read `file(3)` for a description of `enoent`, `eaccess` and `enotdir`. The definition of the file info record can be found by including `file.hrl` from the kernel application, see file(3).

`make_integer(String) -> Result`

Types:

`String = string()`
`Result = {ok,integer()} | {error,nomatch}`

`make_integer/1` returns an integer representation of `String`.
