Transforms
Text transforms a field applies before its value is parsed.
transforms is a list applied in order. An entry is a name, or an object with one key and its arguments.
| Transform | Type | Description |
|---|---|---|
trim | name | Removes leading and trailing whitespace. |
lowercase | name | Converts the string to lowercase. |
uppercase | name | Converts the string to uppercase. |
strip_html | name | Removes HTML markup from the string and decodes entities. |
first | name | Keeps the first line of the string. |
last | name | Keeps the last line of the string. |
replace | object | Replaces every match of a regular expression. |
replace.pattern | string | The regular expression to replace. |
replace.with | string | The replacement string. |
split | object | Splits the string on a separator and keeps one part. |
split.index | integer | The 0-based index of the part to keep; a negative index counts from the end. An index the string does not have is a parse failure, handled by on_invalid. |
split.sep | string | The separator, at least one character. |
join | object | Joins the lines of the string into one line. |
join.sep | string | The string placed where each line break was. |
prefix | string | Adds the given string to the start. |
suffix | string | Adds the given string to the end. |
slice | object | Keeps the characters from start up to end, as JavaScript slice does, so negative indices count from the end. |
slice.end | integer | The index to stop before. Without it, the slice runs to the end. |
slice.start | integer | The index of the first character to keep. |
