Not possible to return a pair key/value from a process

[djoproject]

how to parametrize on a return value ?

        e.g. : echo 1 2 3 | write

if write has an address argument only available on dashed params ?

the goal is to be able to set the adress from the echo, but is is not possible because only tokens are returned, not key/value

Keep in mind that this issue is influenced by discussion in other issues:

• linked with #59

When this issue was written, the goal was to push arguments to the next command, because argument and output stream were merged.

But if the software is updated in the way of the #59 and argument dissociated from input/output stream:

• process "parameters" become the input stream
• process "return" becomes the output stream
• arguments remains static.

In that case, it won't be a design issue anymore but an improvment or an outdated issue.
There are several question to answer before to do anything:

• is there a dict associate to each output (return) or a global dict associated to the output (and maybe updated at each output) or both?
• what will be stored in this dict ? metadata ? real data ?
• what will be able to access this output ?
• because the original goal was to update the next command arguments, shouldn't be easier to give an access to the next command arguments dict ? it will break the command isolation (it looks like a bad idea)
• if an access is given to the next command argument (for the pre process), it should be possible to have an access to the previous command argument (for the post process)
• if the original goal was to update the next command arguments but it is a bad idea because of the command isolation, is all of this really useful ?
