Coverage

This page is generated with the reference. It states what the documentation does not cover, so a reader does not have to find the gap by a compilation.

Operators per source

Ranger has two operator mechanisms. A template operator holds one emission string per target language. A type method is Ranger code in an operator type:<T> block, and the compiler compiles it for the target like any other source, so it works wherever the library compiles.

Source	File	Template operators	Type methods	With an example
Core operators	compiler/Lang.rgr	355	0	27
Standard operators and macros	lib/stdops.rgr	2	0	0
stdlib.rgr	lib/stdlib.rgr	11	38	8
JSON	lib/JSON.rgr	36	2	0
Timers	lib/Timers.rgr	6	0	0
Directory	lib/ranger-dir.rgr	11	0	0

16 more operator sources stay in lib/ and have no page. No maintained program imports them. The generator skips them so a page does not present them as part of the maintained language.

Templates per target

A template is an implementation of the operator for that target language. An operator with the default template (*) writes the same code for every target that has no template of its own.

A default template that holds JavaScript

The * template is also the JavaScript template of many operators. A target that has no template of its own then receives JavaScript in its output file, and the compilation reports success.

This is a scan of the template text for a construct that only JavaScript accepts, such as Math. or parseFloat(. It finds the common ones and not each one, so a count here is a lower limit.
