This works fine:




(make-process :name "my-proc2"
:buffer " *my-proc2*"
:command '("sh" "-c" "echo "hi"nsleep 10necho "there"")
:connection-type 'pipe
:filter (apply-partially 'my-pass-it-on-filter "/tmp/mytmprealtest"))



But if I use a variable like the code below I get Debugger entered--Lisp error: (wrong-type-argument stringp body):



(let ((body "echo "hi"nsleep 10necho "there from var""))
 (make-process :name "my-proc2"
 :buffer " *my-proc2*"
 :command '("sh" "-c" body)
 :connection-type 'pipe
 :filter (apply-partially 'my-pass-it-on-filter "/tmp/mytmprealtest")))


The variable should be a string as well, so why doesn't it work?



The documentation for make-process says:



...
:command COMMAND -- COMMAND is a list starting with the program file
name, followed by strings to give to the program as arguments.
...


The variable was a string as were all other arguments, so I'm not sure what is wrong.

          You've quoted the list:



           :command '("sh" "-c" body)


          So you have passed it a symbol body not the string value of the variable.



          Try:



           :command (list "sh" "-c" body)


          or:



           :command `("sh" "-c" ,body)


          Either of which cause body to be evaluated to its string value.

This Kransekake is a traditional Scandinavian baker's confection. Confectionery is the art of making confections , which are food items that are rich in sugar and carbohydrates. Exact definitions are difficult. [1] In general, though, confectionery is divided into two broad and somewhat overlapping categories, bakers' confections and sugar confections. [2] Bakers' confectionery, also called flour confections , includes principally sweet pastries, cakes, and similar baked goods. Sugar confectionery includes candies ( sweets in British English), candied nuts, chocolates, chewing gum, bubble gum, pastillage, and other confections that are made primarily of sugar. In some cases, chocolate confections (confections made of chocolate) are treated as a separate category, as are sugar-free versions of
