Function Documentation

◆ count_leading_spaces()

int nmodl::test_utils::count_leading_spaces ( std::string text )

Definition at line 17 of file test_utils.cpp.

◆ is_empty()

bool nmodl::test_utils::is_empty ( const std::string & text )

check if string has only whitespaces

Definition at line 26 of file test_utils.cpp.

◆ reindent_text()

std::string nmodl::test_utils::reindent_text	(	const std::string &	text,
		int	indent_level
	)

Reindent nmodl text for text-to-text comparison.

Nmodl constructs defined in test database has extra leading whitespace. This is done for readability reason in nmodl_constructs.cpp. For example, we have following nmodl text with 8 leading whitespaces:

    NEURON {
        RANGE x
    }

We convert above paragraph to:

NEURON { RANGE x }

i.e. we get first non-empty line and count number of leading whitespaces (X). Then for every sub-sequent line, we remove first X characters (assuming those all are whitespaces). This is done because when ast is transformed back to nmodl, the nmodl output is without "extra" whitespaces in the provided input.

count whitespaces for first non-empty line only

make sure we don't remove non whitespaces characters

discard empty lines at very beginning

Variable Documentation

◆ diff_eq_constructs

const std::vector< DiffEqTestCase > nmodl::test_utils::diff_eq_constructs

Definition at line 1309 of file nmodl_constructs.cpp.

◆ nmodl_invalid_constructs

const std::map< std::string, NmodlTestCase > nmodl::test_utils::nmodl_invalid_constructs

Guidelines for adding nmodl text constructs.

As nmodl constructs are used to for testing ast to nmodl transformations, consider following points:

Leading whitespaces or empty lines are removed
Use string literal to define nmodl text When ast is transformed back to nmodl, each statement has newline. Hence for easy comparison, input nmodl should be null terminated. One way to use format:

R"(
    TITLE nmodl title
)"

Do not use extra spaces (even though it's valid)

LOCAL a,b

instead of

LOCAL a, b, c

Use well indented blocks

NEURON {
    RANGE x
}

instead of

  NEURON  {
    RANGE x
}

If nmodl transformation is different from input, third argument could be provided with the expected nmodl.
