= xref:util.adoc[util]::Split
:relfileprefix: ../
:mrdocs:

Split a string on every instance of sep, returning a vector.

== Synopsis

Declared in `<util/string.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
template<typename T = std::span<char const>>
std::vector<T>
Split(
    std::span<char const> const& sp,
    char sep,
    bool include_sep = false);
----

== Description

If sep does not occur in sp, a singleton with the entirety of sp is returned.

Note that this function does not care about braces, so splitting "foo(bar(1),2),3) on ',' will return {"foo(bar(1)", "2)", "3)"}.

== Return Value

The pieces of sp between occurrences of sep.

== Parameters

[cols="1,4"]
