{#op||apply-interpolate||{{s}} {{q}}||{{s}}||
The same as pushing `apply` and then `interpolate` on the stack.#}

{#op||capitalize||{{sl}}||{{s}}||
Returns a copy of {{sl}} with the first character capitalized.#}

{#op||chr||{{i}}||{{s}}||
Returns the single character {{s}} obtained by interpreting {{i}} as an ASCII code.#}

{#op||escape||{{sl}}||{{s}}||
Returns a copy of {{sl}} with quotes and backslashes escaped with a backslash.#}

{#op||from-semver||{{s}}||{{d}}||
Given a basic [SemVer](https://semver.org)-compliant string (with no additional labels) {{s}}, 
it pushes a dictionary {{d}} on the stack containing a **major**, **minor**, and **patch** key/value pairs.#}

{#op||indent||{{sl}} {{i}}||{{s}}||
Returns {{s}} containing {{sl}} indented with {{i}} spaces.#}

{#op||indexof||{{s1}} {{s2}}||{{i}}||
If {{s2}} is contained in {{s1}}, returns the index of the first match or -1 if no match is found. #}

{#op||interpolate||{{s}} {{q}}||{{s}}||
> Substitutes the placeholders included in {{s}} with the values in {{q}}.
> > %note%
> > Notes
> > 
> > * If {{q}} contains symbols or quotations, they are not interpreted. To do so, call `apply` before interpolating or use `apply-interpolate` instead.
> > * You can use the `$#` placeholder to indicate the next placeholder that has not been already referenced in the string.
> > * You can use named placeholders like `$pwd`, but in this case {{q}} must contain a quotation containing both the placeholder names (odd items) and the values (even items).
> 
> > %sidebar%
