Cobra is the common name of various elapid snakes, most of which belonging to the genus Naja.[1]


Biology


All of the known cobras are venomous and many are capable of rearing upwards and producing a hood when threatened.[2]


Known cobras


All members of the genus Naja, the "true" cobras, rear and produce hoods.


Other "cobra" genera and species are as follows:



  • The rinkhals, or ring-necked spitting cobra, Hemachatus haemachatus, so called for its neck band as well as its habit of rearing and spreading its hood when disturbed[3]

  • The king cobra, Ophiophagus hannah[4]

  • The two species of tree cobra, Goldie's tree cobra and black tree cobra[5]

  • The two species of shieldnose cobras, cape coral snake and Aspidelaps scutatus[5]:p.76

  • The two species of black desert cobra, desert black snake and Walterinnesia morgani, neither of which rears or produces a hood[5]:p.65

  • The so-called American cobra, the Eastern coral snake, which also does not rear or produce a hood[5]:p.30


The false water cobra, Hydrodynastes gigas, is the only "cobra" that is not a member of the Elapidae. It does not rear, produces only a slight flattening of the neck, and is only mildly venomous.[5]:p.53

Makefile test if variable is not empty

Makefile test if variable is not empty In a makefile I'm trying to I've created this simplified makefile to demonstrate my problem. Neither make a or make b executes the body of the if, I don't understand why not. make a make b .PHONY: a b a: $(eval MY_VAR = $(shell echo whatever)) @echo MY_VAR is $(MY_VAR) $(info $(MY_VAR)) ifneq ($(strip $(MY_VAR)),) @echo "should be executed" endif @echo done b: $(eval MY_VAR = $(shell echo '')) @echo MY_VAR is $(MY_VAR) $(info $(MY_VAR)) ifneq ($(strip $(MY_VAR)),) @echo "should not be executed" endif @echo done I'm using $ make --version GNU Make 3.81 There are several problems, and misunderstandings. Your MY_VAR is a make variable, set it without a <tab> to its value, and no need to $(eval ...) . MY_VAR:=$(shell echo whatever) is enough. No <tab> before $(info ...) neither, this is make – Zelnes ...
