What I am missing in the new syntax is the possibility to *change* the
value of one header argument or to *remove* one.
There is
,----
| :header-args: tangle testfile.R
`----
Which sets the property header-args, there is
,----
| :header-args+: noweb yes
`----
which adds to header-args, what is missing is
,----
| :header-args-: noweb
`----
which would remove the "noweb yes" from the header arguments and
possibly
,----
| :header-args-+: noweb exec
`----
which would *replace* the "noweb yes" with "noweb exec", so it is
effectively identical to
,----
| :header-args-: noweb
| :header-args+: noweb exec
`----
I know this might be difficult as header-args is simply a string, but I
think when these additions would be there, the old syntax could be
translated into the new syntax.
Cheers,
Rainer
