Re: st: Working with the name of the do file

I have written a program that does this (get the do-file's name from
within the do-file) and much more. It is called -project- and is
currently available from my web site by typing in Stata:

net from http://robertpicard.com/stata

and clicking on the -project- link. Here's the short blurb from the
description page:

project automates the execution of do-files, skipping unchanged
do-files with unchanged dependencies (files used and created by
each do-file). All do-files are logged automatically. Stata's
current working directory is dynamically changed to match the
directory of the current do-file. Files in the do-file's
directory can always be accessed by file name while files
elsewhere can be accessed using a file path that is relative to
the project's main directory. Since full path names are not used,
the whole project directory can be moved or shared with someone
else without having to edit any file paths.

project can verify replication by comparing all files created by
the project (data, tables, graphs, log files, etc.) against
those produced by a replication run. Project files can be listed
in various ways, backed up, and shared with others. project can
also clean up the project directory by moving any file not linked
to the project to an archive directory.

A toy project that runs some examples from the version 12 Stata
reference manuals is included in the ancillary files below.
A reduced version that runs with Stata 9 is also included.
