Invoking the editor from J
How do edit a script while you are in a J session under Unix?
Use these two tiny helpers:
<![CDATA[
EDITOR_j_=: 'vi'
NB. edit files: e 'foo.ijs' later just: e''
e_z_ =: verb define
0 e_z_ y.
:
if. #y. do.
LAST_FILE_j_=:y.
end.
2!:1 EDITOR_j_,' ',LAST_FILE_j_
if. x. do.
<LAST_FILE_j_
else.
0 0 $ ''
end.
)
NB. edit & run files: r 'foo.ijs' later just: r''
r_z_ =: 0!:0 @ (1&e_z_)
]]>
The same code as individual script.
