The most popular variants of the trim function strip only the beginning or end of the string. Typically named ltrim and rtrim respectively, or in the case of Python: lstrip and rstrip . C# uses TrimStart and TrimEnd , and Common Lisp string-left-trim and string-right-trim .
In CSV implementations that do trim leading or trailing spaces, fields with such spaces as meaningful data must be quoted. 1997,Ford,E350," Super luxurious truck "Double quote processing need only apply if the field starts with a double quote. Note, however, that double quotes are not allowed in unquoted fields according to RFC 4180.
This template trims leading and trailing (but not interior) whitespace from a string. The string should be passed as the first unnamed parameter. The parameter must be named |1= if its value contains a = character. You may substitute this template—that is, if this template is used as {}, the resulting wikicode is "clean".
Comma- and space-separated formats often suffer from this problem, since in many contexts those characters are legitimate parts of a data field. Most such files avoid delimiter collision either by surrounding all data fields in double quotes, or only quoting those data fields that contain the delimiter character.
The template trims matched pairs of leading and trailing single and double quotes from a string. Template parameters [Edit template data] Parameter Description Type Status String 1 The string to be trimmed String required See also {{ trim }}
New code should strongly consider {{#invoke:string|replace}} or {{#invoke:MultiReplace|main}}.For backward compatibility, both the input and pattern string are trimmed of surrounding whitespace before processing begins.
The dimension of the column space is called the rank of the matrix and is at most min(m, n). [1] A definition for matrices over a ring is also possible. The row space is defined similarly. The row space and the column space of a matrix A are sometimes denoted as C(A T) and C(A) respectively. [2] This article considers matrices of real numbers
Any string containing only whitespace or no characters at all will be treated as false. Undefined parameter values are tricky: if the first positional parameter was not defined in the template call, then {{{1}}} will evaluate to the literal string "{{{1}}}" (i.e., the 7-character string containing three sets of curly braces around the number 1 ...
