The success of g.os_path_finalize_path/_join suggests that now might
be a good time to support general python expressions in file names.
My present thinking:
1. Delimit such expression by {{exp}} For example:
@thin {{something}}/spam.py
I wonder, however, whether there are any practical uses for this
feature. Can anyone provide such an example that is not equivalent to
an ordinary path expression like
@thin ./../test/test.leo
Important: at present, or very shortly, the following conventions will
apply throughout Leo:
! denotes g.app.loadDir, that is, leo/core
. denotes c.openDirectory, the directory containing the .leo file for c.
~ denotes the users home directory.
So the question is, is there any other place that a) would be useful
and b) could be reasonably denoted by {{something}} If not, I shall
not implement this feature.
2. Assuming that somebody can provide an example where {{something}}
actually would be useful, the question is, in what environment should
{{something}} be executed. My first thought, is an environment in
which sys, os, c, g, and p have their normal meanings. In other
words, I am thinking that 'something' is an expression, not a list of
statements, so that imports are not available.
3. I'll change g.os_path finalize to c.path_finalize and similarly for
g.os_path_finalize_join. This will make c available to these methods.
It remains to be seen whether c is available in all places where
g.os_path_finalize is presently called, but that's most a nit.
Any comments?
Edward
