»Import: strings

The strings import exposes common string operations.

»strings.has_prefix(s, prefix)

Returns true if s starts with prefix.

strings.has_prefix("billing-id", "billing-") // true
strings.has_prefix("bill-id", "billing-")    // false

strings.has_prefix("billing-id", "billing-") // truestrings.has_prefix("bill-id", "billing-")    // false

»strings.has_suffix(s, suffix)

Returns true if s ends with suffix.

strings.has_suffix("billing-id", "id")   // true
strings.has_suffix("billing-name", "id") // false

strings.has_suffix("billing-id", "id")   // truestrings.has_suffix("billing-name", "id") // false

»strings.join(a, sep)

Joins a list with the string supplied by sep.

Multi-dimensional lists are supported, and non-string primitive types will be converted to their string equivalents. Maps and other complex non-list types are not supported.

strings.join(["foo", "bar", "baz"], ".")   // "foo.bar.baz"
strings.join([["foo", "bar"], "baz"], ".") // "foo.bar.baz"
strings.join(["a", 1, 1.01, true], ",")    // "a,1,1.01,true"

strings.join(["foo", "bar", "baz"], ".")   // "foo.bar.baz"strings.join([["foo", "bar"], "baz"], ".") // "foo.bar.baz"strings.join(["a", 1, 1.01, true], ",")    // "a,1,1.01,true"

»strings.trim_prefix(s, prefix)

Trim the prefix from the string s. If the string doesn't have the prefix, then the string is returned unmodified.

strings.trim_prefix("billing-id", "billing-")   // "id"
strings.trim_prefix("bill-id",    "billing-")   // "bill-id"

strings.trim_prefix("billing-id", "billing-")   // "id"strings.trim_prefix("bill-id",    "billing-")   // "bill-id"

»strings.trim_suffix(s, suffix)

Trim the suffix from the string s. If the string doesn't have the suffix, then the string is returned unmodified.

strings.trim_suffix("billing-id", "-id")    // "billing"
strings.trim_suffix("bill-id",    "-foo")   // "bill-id"

strings.trim_suffix("billing-id", "-id")    // "billing"strings.trim_suffix("bill-id",    "-foo")   // "bill-id"

»strings.to_lower(s)

Lowercase the string s.

strings.to_lower("FoO") // "foo"

strings.to_lower("FoO") // "foo"

»strings.to_upper(s)

Uppercase the string s.

strings.to_upper("FoO") // "FOO"

strings.to_upper("FoO") // "FOO"

»strings.split(s, sep)

Split the string 's' via a substring 'sep'. If 'sep' is not contained in 's', the return value will be a single-element list containing only 's'. As a special-case, if the input is already a list, it will be returned as-is. This allows calling the split function when not knowing if the input is already a list or not.

strings.split("foo,bar,baz", ",") // ["foo", "bar", "baz"]
strings.split(["foo", "bar", "baz"], ",") // ["foo", "bar", "baz"]

strings.split("foo,bar,baz", ",") // ["foo", "bar", "baz"]strings.split(["foo", "bar", "baz"], ",") // ["foo", "bar", "baz"]
