Bug ID: 25148
Summary: clang-format: missing options for templates formatting
Product: new-bugs
Version: 3.7
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: new bugs

Classification: Unclassified
When writing templated C++ code, I've converged to the following style for
out-of-class member function definitions:
template< typename Mesh,
typename MeshDependentData,
typename DifferentialOperator,
typename BoundaryConditions,
typename RightHandSide,
typename Matrix >
bool
Solver< Mesh, MeshDependentData, DifferentialOperator, BoundaryConditions,
RightHandSide, Matrix >::
preIterate( const RealType & time,
const RealType & tau,
const MeshType & mesh,
DofVectorType & dofVector,
MeshDependentDataType & mdd )
{
...
}
After reading the documentation for the style options [1], I don't see a way to
achieve exactly this result with clang-format. The closest I got with
"ColumnLimit: 0" is this:
template < typename Mesh, typename MeshDependentData, typename
DifferentialOperator, typename BoundaryConditions, typename RightHandSide,
typename Matrix >
bool
Solver< Mesh, MeshDependentData, DifferentialOperator, BoundaryConditions,
RightHandSide, Matrix >::preIterate( const RealType & time,
const RealType & tau,
const MeshType & mesh,
DofVectorType & dofVector,
MeshDependentDataType & mdd )
{
...
}
The missing options are:
1. Aligning template parameters on separate lines in template declarations and
possibly also member's class qualification. This should be the same as function
arguments list.
2. Breaking after :: if the member's class qualification is "sufficiently long"
(or always for consistency).
