Thank you, that'll do it. However, I am trying to solve another situation.
I have a definitions file and need to set a name to be a list of files
found in a specific directory. One way to do it would be (1):
list=my/dir/file01;
list=my/dir/file02;
...
I don't find it practical when there are lots of files (like 50+).
I could use text editor and shell to do the job. But in case a new file is
added to the directory, or an existing file is removed, I have to re-edit
the definitions file, which is what I want to avoid.
I could also do this (2):
list=`for i in my/dir/*; do echo $i; done`
But then list is not usable with [+FOR+] macro, which is what I also need to be.
I am looking for a way to achieve (1), but with a single definition
line like (2).
One way (maybe naive) to solve this would be to allow shell execution
inside definitions file and then replace the contents of the file (*)
with the result.
Example:
line 0: autogen definitions template.tpl;
line 1: `for i in my/dir/*; do echo list="${i};"; done`
Parsing the first line would result into:
line 0: autogen definitions template.tpl;
line 1: list=my/dir/file01;
line 2: list=my/dir/file02;
...
Parsing would of course resume from the first line.

Not the file on the disk, but an in memory image (the content of the
parser's buffer).
