Internal Plugins

There are some plugins that are provided with the nadi_core library. They are part of the library, so users can directly use them.

For example in the following tasks file, the functions that are highlighted are functions available from the core plugins. Other functions need to be loaded from plugins.

# sample .tasks file which is like a script with functions
node print_attrs("uniqueID")
node show_node()
network save_graphviz("/tmp/test.gv")

node[WV04113,WV04112,WV04112] print_attr_toml("testattr2")
node render("{NAME} {uniqueID} {_Dam_Height_(Ft)?}")
node list_attr("; ")
# some functions can take variable number of inputs
network calc_attr_errors(
    "Dam_Height_(Ft)",
    "Hydraulic_Height_(Ft)",
    "rmse", "nse", "abserr"
)
node sum_safe("Latitude")
node.inputsfirst render("Hi {SUM_ATTR}")
# multiple line for function arguments
network save_table(
	"test.table",
	"/tmp/test.tex",
	true,
	radius=0.2,
	start = 2012-19-20,
	end = 2012-19-23 12:04
	)
node set_attrs(testattr = 2)
node set_attrs_render(testattr2 = "{testattr:calc(+2)}")
node[WV04112] render("{testattr} {testattr2}")

# here we use a complicated template that can do basic logic handling
node set_attrs_render(
    testattr2 = "=(if (and (st+has 'Latitude) (> (st+num 'Latitude) 39)) 'true 'false)"
)
# same thing can be done if you need more flexibility in variable names
node load_toml_string(
    "testattr2 = =(if (and (st+has 'Latitude) (> (st+num 'Latitude) 39)) 'true 'false)"
)
# selecting a list of nodes to run a function
node[
	# comment here?
    WV04113,
    WV04112
] print_attr_toml("testattr2")
# selecting a path
node[WV04112 -> WV04113] render("=(> 2 3)")
