I've got some batch scripts I wanted to convert to D. I'd like
users to run them using rdmd, so it's obvious where the source
code lives and easy to modify. The problem is that the batch
scripts I want to convert rely on the %~dp0 variable, which
contains the path to the batch script itself. Note that this
variable is different then the current directory. I haven't
been able to find a nice way to do this in D. (Note that
thisExePath won't work because rdmd compiles the code to a
temporary directory, which makes sense.)
Having known about the special __FILE__ and __LINE__ traits, I
figured there might be a trait for the file directory as well,
but it appears there is none. I'd like to see what people
think about adding a new trait for this. Maybe something like
__FILE_DIR__? This would contain the directory of the
source-code file it appears in. Also if this trait was added,
one could argue that a trait containing the path and the
filename should also be added, maybe something like
__FILE_FULL_PATH__?
P.S. If you know of an existing solution to this problem please
let me know.
For others who may see this thread, the __FULL_FILE_PATH__
special trait was added to the dmd compiler with this PR:
https://github.com/dlang/dmd/pull/5959
At the time of this post, the latest released version of D is
2.071.1, so this trait should be available on any release after
that.
