Xdev is an excellent developer tool for excellent developers. It contains miscellaneous and/or interactive debugging tools.

This started as a project for myself to contain development related tools that I wouldn’t want to ship with a package itself (where as ubelt contains the tools used in programs themselves). I’ve polished it up over the years, and it’s become a reasonably useful package with tools I could see others making use of.

This is the CLI:

usage: xdev [-h] [--version] {info,codeblock,sed,find,tree,pint,pyfile,pyversion,editfile,format_quotes,freshpyenv,docstubs,available_package_versions,dirstats} ...

Remarks

Perhaps I should just use ipdb but I often just like to directly embed with IPython whenever I want:

import xdev
xdev.embed()

Or wherever I want whenever there is an exception.

import xdev
with xdev.embed_on_exception:
    some_code()

I don’t feel like I need ipdb’s other features.

I also like to

def func(a=1, b=2, c=3):
    """
    Example:
        >>> from this.module import *  # import contextual namespace
        >>> import xinspect
        >>> globals().update(xinspect.get_func_kwargs(func))  # populates globals with default kwarg value
        >>> print(a + b + c)
        6
    """

But I know these things are a little dirty.

But these aren’t production practices. These are development tricks and life hacks to make working faster.

Also see xinspect for things like autogen_imports

>>> import ubelt as ub
>>> source = ub.codeblock(
>>>     '''
>>>     p = os.path.dirname(join('a', 'b'))
>>>     glob.glob(p)
>>>     ''')
>>> # Generate a list of lines to fix the name errors
>>> lines = autogen_imports(source=source)
>>> print(lines)
['import glob', 'from os.path import join', 'import os']

The CLI

The xdev CLI is getting kinda nice, although it is a bit of a hodgepodge of functionality (much like this library).

pip install xdev
xdev --help

It contains functionality that I generally use when developing on my setup, but I often find lacking in the setup of others.

For instance the tree UNIX command is amazing, but not everyone has it installed, and getting it via apt requires sudo privileges. Meanwhile xdev can be installed in user space via pip, so this provides me with an easy way to get tree on someone’s system while helping them debug.

Other examples are sed, find, pyfile, and pyversion. Look at the --help for more info on them.

The dirstats function is like a buffed up tree. In addition to printing the directory tree structure it inspects the contents of the tree and summarizes things like: number of lines per type of file. For Python files it breaks up the analysis into code-lines and docstring lines to give a better sense of project complexity.

For repo maintence I use this package in conjunction with xcookie. I use xcookie to generate the package structure and then xdev helps fill in the details. Specifically the availpkg and docstubs commands.

The availpkg command has been indispensable for me when writing requirements.txt files. If you need to find good versions of a package — especially a binary one, e.g. numpy — for different versions of Python and would like the appropirate requirements.txt syntax to be generated for you, take a look at availpkg. It also provides an overview of what versions of a package are available for what operating systems / CPU architectures.

The docstubs command is designed to turn google-style docstrings into proper type annotation stubs. It “works on my machine” and currently requires a custom monkey patched mypy. See the code for details, it is possible to use, but it is still very raw. I do think it can evolve into a tool.
