C1R
This programming language may be used to instruct a computer to perform a task.

Execution method:	Compiled (machine code)
Garbage collected:	No
Parameter passing methods:	By value
Type safety:	Unsafe
Type strength:	Weak
Type compatibility:	Nominative
Type expression:	Explicit
Type checking:	Static

Listed below are all of the tasks on Rosetta Code which have been solved using C1R.

C1R is a general-purpose, procedural, imperative computer programming language, partially developed by André van Delft in 2011. It is a small extension to the well known compatible with::C programming language, allowing for very small programs that implement tasks that are implemented by C programs at RosettaCode.org.

C1R can also be regarded as an adaptive language, as the set of valid C1R programs varies with the C implementations for tasks at Rosetta Code.

The development of C1R has been inspired on the HQ9+ and C0H programming languages. HQ9+ accepts "H" in its source to print "Hello World!". C0H improves over HQ9+ by offering the full power of the C language; moreover, C0H offers a shorter path to writing a Hello World program: just create an empty file. C1R allows the user to submit a text file with just a simple reference of a task implemented in C at Rosetta Code; that reference is the implementation of the task in C1R. E.g., the following C1R program <lang c> Hello_world/Text </lang> does exactly the same as the C program listed at the "Hello_world/Text" page, namely print "Goodbye world!".

Implementation

C1R is implemented using a Shell script that calls the C compiler. The script starts by testing whether C code should be downloaded from the Rosetta Code site. The Quine task is treated as a special case. See C1R Implementation

Acknowledgement

When hearing of C0H, Jelle van Zeijl suggested to make a similar language based on downloading C code from the Rosetta Code site.

Documentation

To get a reference document on C1R, it is advised to upgrade a reference document on the "C" programming language, and attach a Post-it note stating C1R is like C, except that in case it contains just 1 line that directs to a Rosetta Code URL with a valid C implementation.
