## Linking to your program
The `make install` command takes care of installing the QMCkl shared library on the user machine.
Once installed, add `-lqmckl` to the list of compiler options.
In some cases (e.g. when using custom `prefix` during configuration), the QMCkl library might end up installed in a directory, which is absent in the default `$LIBRARY_PATH`.
In order to link the program against QMCkl, the search paths can be modified as follows:
`export LIBRARY_PATH=$LIBRARY_PATH:<path_to_qmckl>/lib`
(same holds for `$LD_LIBRARY_PATH`). The `<path_to_qmckl>` has to be replaced with the prefix used during the installation.
If your project relies on the CMake build system, feel free to use the
[FindQMCKL.cmake](https://github.com/TREX-CoE/qmckl/blob/master/cmake/FindQMCKL.cmake)
module to find and link the QMCkl library automatically.

#+TITLE: Code examples
#+SETUPFILE: ../tools/theme.setup
#+INCLUDE: ../tools/lib.org
In this section, we present examples of usage of QMCkl.
For simplicity, we assume that the wave function parameters are stores
in a [[https://github.com/TREX-CoE/trexio][TREXIO]] file.
* Checking errors
All QMCkl functions return an error code. A convenient way to handle
errors is to write an error-checking function that displays the
error in text format and exits the program.
#+NAME: qmckl_check_error
#+begin_src f90
subroutine qmckl_check_error(rc, message)
use qmckl
implicit none
integer(qmckl_exit_code), intent(in) :: rc
character(len=*) , intent(in) :: message
character(len=128) :: str_buffer
if (rc /= QMCKL_SUCCESS) then
print *, message
call qmckl_string_of_error(rc, str_buffer)
print *, str_buffer
call exit(rc)
end if
end subroutine qmckl_check_error
#+end_src
* Computing an atomic orbital on a grid
:PROPERTIES:
:header-args: :tangle ao_grid.f90
:END:
The following program, in Fortran, computes the values of an atomic
orbital on a regular 3-dimensional grid. The 100^3 grid points are
automatically defined, such that the molecule fits in a box with 5
atomic units in the borders.
This program uses the ~qmckl_check_error~ function defined above.
To use this program, run
#+begin_src bash :tangle no
$ ao_grid <trexio_file> <AO_id> <point_num>
#+end_src
#+begin_src f90 :noweb yes
<<qmckl_check_error>>
program ao_grid
use qmckl
implicit none
integer(qmckl_context) :: qmckl_ctx ! QMCkl context
integer(qmckl_exit_code) :: rc ! Exit code of QMCkl functions
character(len=128) :: trexio_filename
character(len=128) :: str_buffer
integer :: ao_id
integer :: point_num_x
integer(c_int64_t) :: nucl_num
double precision, allocatable :: nucl_coord(:,:)
integer(c_int64_t) :: point_num
integer(c_int64_t) :: ao_num
integer(c_int64_t) :: ipoint, i, j, k
double precision :: x, y, z, dr(3)
double precision :: rmin(3), rmax(3)
double precision, allocatable :: points(:,:)
double precision, allocatable :: ao_vgl(:,:,:)
#+end_src
Start by fetching the command-line arguments:
#+begin_src f90
if (iargc() /= 3) then
print *, 'Syntax: ao_grid <trexio_file> <AO_id> <point_num>'
call exit(-1)
end if
call getarg(1, trexio_filename)
call getarg(2, str_buffer)
read(str_buffer, *) ao_id
call getarg(3, str_buffer)
read(str_buffer, *) point_num_x
if (point_num_x < 0 .or. point_num_x > 300) then
print *, 'Error: 0 < point_num < 300'
call exit(-1)
end if
#+end_src
Create the QMCkl context and initialize it with the wave function
present in the TREXIO file:
#+begin_src f90
qmckl_ctx = qmckl_context_create()
rc = qmckl_trexio_read(qmckl_ctx, trexio_filename, 1_8*len(trim(trexio_filename)))
call qmckl_check_error(rc, 'Read TREXIO')
#+end_src
We need to check that ~ao_id~ is in the range, so we get the total
number of AOs from QMCkl:
#+begin_src f90
rc = qmckl_get_ao_basis_ao_num(qmckl_ctx, ao_num)
call qmckl_check_error(rc, 'Getting ao_num')
if (ao_id < 0 .or. ao_id > ao_num) then
print *, 'Error: 0 < ao_id < ', ao_num
call exit(-1)
end if
#+end_src
Now we will compute the limits of the box in which the molecule fits.
For that, we first need to ask QMCkl the coordinates of nuclei.
#+begin_src f90
rc = qmckl_get_nucleus_num(qmckl_ctx, nucl_num)
call qmckl_check_error(rc, 'Get nucleus num')
allocate( nucl_coord(3, nucl_num) )
rc = qmckl_get_nucleus_coord(qmckl_ctx, 'N', nucl_coord, 3_8*nucl_num)
call qmckl_check_error(rc, 'Get nucleus coord')
#+end_src
We now compute the coordinates of opposite points of the box, and
the distance between points along the 3 directions:
#+begin_src f90
rmin(1) = minval( nucl_coord(1,:) ) - 5.d0
rmin(2) = minval( nucl_coord(2,:) ) - 5.d0
rmin(3) = minval( nucl_coord(3,:) ) - 5.d0
rmax(1) = maxval( nucl_coord(1,:) ) + 5.d0
rmax(2) = maxval( nucl_coord(2,:) ) + 5.d0
rmax(3) = maxval( nucl_coord(3,:) ) + 5.d0
dr(1:3) = (rmax(1:3) - rmin(1:3)) / dble(point_num_x-1)
#+end_src
We now produce the list of point coordinates where the AO will be
evaluated:
#+begin_src f90
point_num = point_num_x**3
allocate( points(point_num, 3) )
ipoint=0
z = rmin(3)
do k=1,point_num_x
y = rmin(2)
do j=1,point_num_x
x = rmin(1)
do i=1,point_num_x
ipoint = ipoint+1
points(ipoint,1) = x
points(ipoint,2) = y
points(ipoint,3) = z
x = x + dr(1)
end do
y = y + dr(2)
end do
z = z + dr(3)
end do
#+end_src
We give the points to QMCkl:
#+begin_src f90
rc = qmckl_set_point(qmckl_ctx, 'T', points, point_num)
call qmckl_check_error(rc, 'Setting points')
#+end_src
We allocate the space required to retrieve the values, gradients and
Laplacian of all AOs, and ask to retrieve the values of the
AOs computed at the point positions.
#+begin_src f90
allocate( ao_vgl(ao_num, 5, point_num) )
rc = qmckl_get_ao_basis_ao_vgl(qmckl_ctx, ao_vgl, ao_num*5_8*point_num)
call qmckl_check_error(rc, 'Setting points')
#+end_src
We finally print the value of the AO:
#+begin_src f90
do ipoint=1, point_num
print '(3(F16.10,X),E20.10)', points(ipoint, 1:3), ao_vgl(ao_id,1,ipoint)
end do
#+end_src
#+begin_src f90
deallocate( nucl_coord, points, ao_vgl )
end program ao_grid
#+end_src
