# Pull request checklist
Please review the following items before submitting a pull request. This list
can also be used when reviewing pull requests.
* Verify that new files have a license with correct file name.
* Run `git diff` on all modified files to look for spurious changes such as
`#include <iostream>`.
* If you added code that causes the compiler to emit a new error message, make
sure that you also added a test that causes that error message to appear
and verifies its correctness.
* Annotate the code and tests with appropriate references to constraint and
requirement numbers from the Fortran standard. Do not include the text of
the constraint or requirement, just its number.
* Alphabetize arbitrary lists of names.
* Check dereferences of pointers and optionals where necessary.
* Ensure that the scopes of all functions and variables are as local as
possible.
* Try to make all functions fit on a screen (40 lines).
* Build and test with both GNU and clang compilers.
* When submitting an update to a pull request, review previous pull request
comments and make sure that you've actually made all of the changes that
were requested.
## Follow the style guide
The following items are taken from the [C++ style guide](C++style.md). But
even though I've read the style guide, they regularly trip me up.
* Run clang-format using the git-clang-format script from LLVM HEAD.
* Make sure that all source lines have 80 or fewer characters. Note that
clang-format will do this for most code. But you may need to break up long
strings.
* Review declarations for proper use of `constexpr` and `const`.
* Follow the C++ [naming guidelines](C++style.html#naming)
* Ensure that the names evoke their purpose and are consistent with existing code.
* Used braced initializers.
* Review pointer and reference types to make sure that you're using them
appropriately. Note that the [C++ style guide](C++style.md) contains a
section that describes all of the pointer types along with their
characteristics.
* Declare non-member functions ```static``` when possible. Prefer
```static``` functions over functions in anonymous namespaces.
