'How to get the program name in a fish shell script?

In bash, as in ruby, the program name is given by $0. What is it in fish? I can do the following if I have to:

set PROGRAM (ps --no-header -o args -p %self | egrep -o '\S+')[2]

But I'm sure the program name must be already available somewhere. I could also set the program name in variable at the stub of each program, but that has maintenance problems.

shell fish

Solution 1:^[1]

For fish use $_ for program name.

Solution 2:^[2]

`fish` `3.x`

status current-command

See Deprecations section of the 3.0 documentation.

`fish` `2.x`

Use $_ for program name.

See Programmable title section of the 2.0 documentation.

Solution 3:^[3]

In the docs you can see that as of version 3.4.1 you can simply use

echo (status basename)
