The {(...)}
"expression markup" allows for a variety of string and formatting operations to be performed from within markup. Operations defined by this recipe include substr, ftime, strlen, rand, toupper / tolower, ucfirst, ucwords, pagename and asspaced.
substr
The "substr" expression extracts portions of a string. The arguments are
- the string to be processed. Always quote the string to be processed.
- the initial position of the substring. Note that the initial position argument is zero-based (i.e., the first character is referenced via a "0").
- the number of characters to extract
{(substr "PmWiki" 2 3)} {(substr "PmWiki" 2)} {(substr "PmWiki" 0 1)} {(substr "PmWiki" 0 -3)} {(substr "PmWiki" -3)} | Wik Wiki P PmW iki |
To obtain the last n characters of a string use {(substr "string" -n)}
To truncate the last n characters of a string use (substr "string" 0 -n)}
ftime
"Ftime" expressions are used for date and time formatting. The generic form is
{(ftime "fmt" "when")}
{(ftime fmt="fmt" when="when")}
where fmt is a formatting string and when is the time to be formatted. The arguments can be in either order and may use the optional "fmt=" and "when=" labels.
Examples:
{(ftime)} {(ftime fmt="%F %H:%M")} {(ftime %Y)} {(ftime fmt=%T)} {(ftime when=tomorrow)} {(ftime fmt="%Y-%m-%d" yesterday)} {(ftime week %F)} {(ftime fmt=%D month)} {(ftime fmt="%a%e %b" when="next week")} | March 29, 2024, at 02:09 PM 2024-03-29 14:09 2024 14:09:32 March 30, 2024, at 12:00 AM 2024-03-28 1970-01-01 01/01/70 Mon 1 Apr |
The fmt parameter is whatever is given by "fmt=", the first parameter containing a '%', or else the site's default. The formatting codes are described at http://php.net/strftime. In addition to those, 's' produces Unix timestamps. Some common formatting strings:
%F # ISO-8601 dates "2024-03-29" %s # Unix timestamp "1711717772" %H:%M:%S # time as hh:mm:ss "14:09:32" %m/%d/%Y # date as mm/dd/yyyy "03/29/2024" "%A, %B %d, %Y" # in words "Friday, March 29, 2024"
The when parameter understands many different date formats. The when parameter is whatever is given by "when=", or whatever parameter remains after determining the format parameter. Some examples:
2007-04-11 # ISO-8601 dates 20070411 # dates without hyphens, slashes, or dots 2007-03 # months @1176304315 # Unix timestamps (seconds since 1-Jan-1970 00:00 UTC) now # the current time today # today @ 00:00:00 yesterday # yesterday @ 00:00:00 "next Monday" # relative dates "last Thursday" # relative dates "-3 days" # three days ago "+2 weeks" # two weeks from now
Note: If you want to convert a Unix timestamp you must prefix with the @. Thus, "{(ftime "%A, %B %d, %Y" @1231116927)}"
.
The when parameter uses PHP's strtotime function to convert date strings according to the GNU date input formats; as of this writing it only understands English phrases in date specifications.
The variable $FTimeFmt
can be used to override the default date format used by the "ftime" function. The default $FTimeFmt
is $TimeFmt
.
strlen
The "strlen" expression returns the length of a string. The first argument is the string to be measured.
{(strlen "{$:Summary}")} | 32 |
rand
The "rand" expression returns a random integer. The first argument is the minimum number to be returned and the second argument is the maximum number to be returned. If called without the optional min, max arguments rand() returns a pseudo-random integer between 0 and RAND_MAX. If you want a random number between 5 and 15 (inclusive), for example, use rand (5, 15).
{(rand)} | 973057222 |
toupper / tolower
The "toupper" and "tolower" expressions convert a string into uppercase or lowercase. The first argument is the string to be processed.
{(toupper "{$:Summary}")} {(tolower "{$:Summary}")} | STRING AND FORMATTING OPERATIONS string and formatting operations |
ucfirst
The "ucfirst" expression converts the first character of a string to uppercase. The first argument is the string to be processed.
{(ucfirst "{$:Summary}")} | String and formatting operations |
ucwords
The "ucwords" expression converts the first character of each word in a string to uppercase. The first argument is the string to be processed.
{(ucwords "{$:Summary}")} | String And Formatting Operations |
pagename
The "pagename" expression builds a pagename from a string. The first argument is the string to be processed.
{(pagename "{$:Summary}")} | PmWiki.StringAndFormattingOperations |
asspaced
The "asspaced" expression formats wikiwords. The first argument is the string to be processed.
{(asspaced "{$FullName}")} | Pm Wiki.Markup Expressions |
Nesting expressions
Markup expressions can be nested:
{(tolower (substr "Hello World" 2))} | llo world |
Notes
- Some of the string-processing markups may not work properly on UTF-8 characters or escaped sequences.
- The ftime markup does not work with some ISO 8601 dates (because a time of 24:00 is invalid)such as:
{(ftime fmt="%m/%d/%Y @ %H:%M:%S" when="20070626T2400")} {(ftime fmt="%H:%M:%S" when="20070626T2400")} | 06/27/2007 @ 00:00:00 00:00:00 |
- is it possible to display the time in another time zone, eg
NowTime: {(ftime fmt="%F %H:%M")} {(ftime when='TZ=:Europe/London" ')} {(ftime when='TZ=Europe/London" 0 days')} {(ftime when="TZ='Europe/London' 2004-10-31 08:00")} {(ftime when='TZ="Pacific/Auckland" {$:NowTime}')} | NowTime: 2024-03-29 14:09 January 01, 1970, at 01:00 AM January 01, 1970, at 01:00 AM October 31, 2004, at 12:00 AM (ftime when='TZ=Pacific/Auckland {2024-03-29 14:09')} |
