Mercurial File Finder Plugin for Setuptools

This package provides a simple, command-based file finder plugin for setuptools. Once installed, one can create distributions using a pacakge that has been checked out with Mercurial.

So let’s create a workspace:

>>> import tempfile
>>> ws = tempfile.mkdtemp()

Since the workspace is not a mercurial repository, the finder returns an empty list and leaves an error message in the logs:

>>> from z3c.setuptools_mercurial import finder

>>> finder.find_files(ws)
abort: There is no Mercurial repository here (.hg not found)! (code 255)
<BLANKLINE>
[]

Also, if the directory does not exist, we get an error message, but an empty result set:

>>> finder.find_files('/foo')
[Errno 2] No such file or directory: '/foo'
[]

Let’s now create a new repository:

>>> import os
>>> repos = os.path.join(ws, 'test')
>>> cmd('hg init ' + repos)

The finder still fails with error code 1, since no file is yet added in the repository:

>>> finder.find_files(repos)
(code 1)
[]

Let’s now add soem directories and files and the finder should be happy.

>>> cmd('touch ' + os.path.join(repos, 'data.txt'))
>>> cmd('hg add ' + os.path.join(repos, 'data.txt'))

>>> cmd('mkdir ' + os.path.join(repos, 'dir1'))
>>> cmd('touch ' + os.path.join(repos, 'dir1', 'data1.txt'))
>>> cmd('hg add ' + os.path.join(repos, 'dir1', 'data1.txt'))

>>> cmd('mkdir ' + os.path.join(repos, 'dir1', 'dir11'))
>>> cmd('touch ' + os.path.join(repos, 'dir1', 'dir11', 'data1.txt'))
>>> cmd('hg add ' + os.path.join(repos, 'dir1', 'dir11', 'data1.txt'))

>>> finder.find_files(repos)
['data.txt',
 'dir1/data1.txt',
 'dir1/dir11/data1.txt']

Note that the result of the finder is always a list of relative locations based on the input directory.

>>> finder.find_files(os.path.join(repos, 'dir1'))
['data1.txt',
 'dir11/data1.txt']
