|---|
| 1964 | |
|---|
| 1965 | MT::Util - Movable Type utility functions |
|---|
| 1966 | |
|---|
| 1967 | =head1 SYNOPSIS |
|---|
| 1968 | |
|---|
| 1969 | use MT::Util qw( functions ); |
|---|
| 1970 | |
|---|
| 1971 | =head1 DESCRIPTION |
|---|
| 1972 | |
|---|
| 1973 | I<MT::Util> provides a variety of utility functions used by the Movable Type |
|---|
| 1974 | libraries. |
|---|
| 1975 | |
|---|
| 1976 | =head1 USAGE |
|---|
| 1977 | |
|---|
| 1978 | =head2 start_end_day($ts) |
|---|
| 1979 | |
|---|
| 1980 | Given I<$ts>, a timestamp in form C<YYYYMMDDHHMMSS>, calculates the timestamp |
|---|
| 1981 | corresponding to the start of the same day, and, if called in list context, |
|---|
| 1982 | the end of the day. If called in scalar context, returns one timestamp |
|---|
| 1983 | corresponding to the start of the day; if called in list context, returns two |
|---|
| 1984 | timestamps, for the start and end of the day. |
|---|
| 1985 | |
|---|
| 1986 | For example, given C<20020410160406>, returns C<20020410000000> in scalar |
|---|
| 1987 | context, and C<20020410000000> and C<20020410235959> in list context. |
|---|
| 1988 | |
|---|
| 1989 | =head2 start_end_week($ts) |
|---|
| 1990 | |
|---|
| 1991 | Given I<$ts>, a timestamp in form C<YYYYMMDDHHMMSS>, calculates the timestamp |
|---|
| 1992 | corresponding to the start of the week, and, if called in list context, the |
|---|
| 1993 | end of the week. If called in scalar context, returns one timestamp |
|---|
| 1994 | corresponding to the start of the week; if called in list context, returns two |
|---|
| 1995 | timestamps, for the start and end of the week. |
|---|
| 1996 | |
|---|
| 1997 | A week is defined as starting on Sunday. |
|---|
| 1998 | |
|---|
| 1999 | For example, given C<20020410160406>, returns C<20020407000000> in scalar |
|---|
| 2000 | context, and C<20020407000000> and C<20020413235959> in list context. |
|---|
| 2001 | |
|---|
| 2002 | =head2 start_end_month($ts) |
|---|
| 2003 | |
|---|
| 2004 | Given I<$ts>, a timestamp in form C<YYYYMMDDHHMMSS>, calculates the timestamp |
|---|
| 2005 | corresponding to the start of the month, and, if called in list context, |
|---|
| 2006 | the end of the month. If called in scalar context, returns one timestamp |
|---|
| 2007 | corresponding to the start of the month; if called in list context, returns two |
|---|
| 2008 | timestamps, for the start and end of the month. |
|---|
| 2009 | |
|---|
| 2010 | For example, given C<20020410160406>, returns C<20020401000000> in scalar |
|---|
| 2011 | context, and C<20020401000000> and C<20020430235959> in list context. |
|---|
| 2012 | |
|---|
| 2013 | =head2 offset_time_list($unix_ts, $blog [, $direction ]) |
|---|
| 2014 | |
|---|
| 2015 | Given I<$unix_ts>, a timestamp in Unix epoch format (seconds since 1970), |
|---|
| 2016 | applies the timezone offset specified in the blog I<$blog> (either an |
|---|
| 2017 | I<MT::Blog> object or a numeric blog ID). If daylight saving time is in |
|---|
| 2018 | effect in the local time zone (determined using the return value from |
|---|
| 2019 | I<localtime()>), the offset is automatically adjusted. |
|---|
| 2020 | |
|---|
| 2021 | Returns the return value of I<gmtime()> given the adjusted Unix timestamp. |
|---|
| 2022 | |
|---|
| 2023 | =head2 format_ts($format, $ts, $blog) |
|---|
| 2024 | |
|---|
| 2025 | Given a timestamp I<$ts> in form C<YYYYMMDDHHMMSS>, applies the format |
|---|
| 2026 | specified in I<$format> and returns the formatted string. |
|---|
| 2027 | |
|---|
| 2028 | If specified, I<$blog> should be an I<MT::Blog> object, from which the |
|---|
| 2029 | date/time formatting language preference is taken (e.g. English, French, etc.). |
|---|
| 2030 | If unspecified, English formatting is used. |
|---|
| 2031 | |
|---|
| 2032 | If I<$format> is C<undef>, and I<$blog> is specified, I<format_ts> will |
|---|
| 2033 | use a language-specific default format; if a language-specific format is not |
|---|
| 2034 | defined, or if I<$blog> is unspecified, the default format used is |
|---|
| 2035 | C<%B %e, %Y %I:%M %p>. |

| 2039 | Returns the number of days in the month I<$month> in the year I<$year>. |
|---|
| 2040 | I<$month> should be numeric, starting at C<1> for C<January>. I<$year> should |
|---|
| 2041 | be a 4-digit year. The number of days is automatically adjusted in a leap |
|---|
| 2042 | year. |
|---|
| 2043 | |
|---|
| 2044 | =head2 wday_from_ts($year, $month, $day) |
|---|
| 2045 | |
|---|
| 2046 | Returns the numeric day of the week, in the range C<0>-C<6>, where C<0> is |
|---|
| 2047 | C<Sunday>, for the date specified in I<$year>, I<$month>, and I<$day>. |
|---|
| 2048 | I<$year> should be a 4-digit year; I<$month> a numeric value in the range |
|---|
| 2049 | C<1>-C<12>; and I<$day> the numeric day of the month. |

|---|
| 2057 | |
|---|
| 2058 | Munges a string I<$str> so that it is suitable for use as a file/directory |
|---|
| 2059 | name. HTML is removed; HTML-entities are removed; non-word/space characters |
|---|
| 2060 | are removed; spaces are changed to underscores; the entire string is |
|---|
| 2061 | converted to lower-case. |
|---|
| 2062 | |
|---|
| 2063 | For example, the string C<Foo E<lt>bE<gt>BarE<lt>/bE<gt> E<amp>quot;BazE<amp>quot;> would be transformed into C<foo_bar_baz>. |
|---|
| 2064 | |

|---|
| 2066 | |
|---|

|---|
| 2068 | transformed string. |
|---|
| 2069 | |
|---|
| 2070 | If I<HTML::Entities> is available, and if the configuration setting |
|---|
| 2071 | I<NoHTMLEntities> is not set, uses I<HTML::Entities> for entity-encoding. |
|---|
| 2072 | Otherwise, very simple encoding is done to catch the most common characters |
|---|
| 2073 | that need encoding. |
|---|
| 2074 | |
|---|
| 2075 | =head2 decode_html($str) |
|---|
| 2076 | |
|---|
| 2077 | Decodes any HTML entities in I<$str> into the corresponding characters and |
|---|
| 2078 | returns the transformed string. |
|---|
| 2079 | |
|---|
| 2080 | If I<HTML::Entities> is available, and if the configuration setting |
|---|
| 2081 | I<NoHTMLEntities> is not set, uses I<HTML::Entities> for entity-decoding. |
|---|
| 2082 | Otherwise, very simple decoding is done to catch the most common entities |
|---|
| 2083 | that need decoding. |
|---|
| 2084 | |
|---|
| 2085 | =head2 remove_html($str) |
|---|
| 2086 | |
|---|
| 2087 | Removes any HTML tags from I<$str> and returns the result. |
|---|
| 2088 | |
|---|
| 2089 | =head2 encode_js($str) |
|---|
| 2090 | |
|---|
| 2091 | Escapes/encodes any special characters in I<$str> so that the string can be |
|---|
| 2092 | used safely as the value in Javascript; returns the transformed string. |
|---|
| 2093 | |
|---|
| 2094 | =head2 encode_php($str [, $type ]) |
|---|
| 2095 | |
|---|
| 2096 | Escapes/encodes any special characters in I<$str> so that the string can be |
|---|
| 2097 | used safely as the value in PHP code; returns the transformed string. |
|---|
| 2098 | |
|---|
| 2099 | I<$type> can be either C<qq> (double-quote interpolation), C<here> (heredoc |
|---|
| 2100 | interpolation), or C<q> (single-quote interpolation). C<q> is the default. |
|---|
| 2101 | |
|---|
| 2102 | =head2 spam_protect($email_address) |
|---|
| 2103 | |
|---|
| 2104 | Given an email address I<$email_address>, encodes any characters that will |
|---|
| 2105 | identify it as an email address (C<:>, C<@>, and C<.>) into HTML entities, |
|---|
| 2106 | so that spam harvesters will not see the email address as easily. Returns |
|---|
| 2107 | the transformed address. |
|---|
| 2108 | |
|---|
| 2109 | =head2 is_valid_email($email_address) |
|---|
| 2110 | |
|---|
| 2111 | Checks the email address I<$email_address> for syntax validity; if the |
|---|
| 2112 | address--or part of it--is valid, I<is_valid_email> returns the valid (part |
|---|
| 2113 | of) the email address. Otherwise, it returns C<0>. |

|---|
| 2115 | =head2 perl_sha1_digest($msg) |
|---|
| 2116 | |
|---|

|---|
| 2118 | representation. Use perl_sha1_digest_hex to get a printable string. |
|---|
| 2119 | |
|---|
| 2120 | =head2 perl_sha1_digest_hex($msg) |
|---|
| 2121 | |
|---|
| 2122 | Returns a SHA1 digest of $msg. The result is an ASCII string of hex |
|---|
| 2123 | digits. Use perl_sha1_digest to get a binary representation. |
|---|
| 2124 | |
|---|
| 2125 | =head2 dsa_verify(Key => $key, Signature => $sig, |
|---|
| 2126 | [ Message => $msg | $Digest => $dgst ]) |
|---|
| 2127 | |
|---|
| 2128 | Verifies that sig is a DSA signature of $msg (or $dgst) produced using |
|---|
| 2129 | the private half of the public key given in $key. Requires |
|---|
| 2130 | Math::BigInt but doesn't call for any non-perl libraries. |
|---|

|---|
| 2132 | =head2 get_newsbox_html($newsbox_url, $kind) |
|---|
| 2133 | |
