When I press space, it will throw error $ Exception in thread Thread-16: Traceback (most recent call last): File "/usr/lib/python2.7/threading.py", line 801, in __bootstrap_inner self.run() File "/usr/lib/python2.7/threading.py", line 754, in run self.__target(*self.__args, **self.__kwargs) File "/home/wpm/.linuxbrew/Cellar/ergonomica/1.1.4/bin/lib/prompt_toolkit/intn completions = list(buffer.completer.get_completions(document, complete_even) File "/home/wpm/.linuxbrew/Cellar/ergonomica/1.1.4/bin/lib/interface/completes for result in complete(self.verbs, document.text): File "/home/wpm/.linuxbrew/Cellar/ergonomica/1.1.4/bin/lib/interface/completee options = [i for i in options if i.startswith(last_word)] UnicodeDecodeError: 'ascii' codec can't decode byte 0xe5 in position 0: ordinal)

With python 2, ergonomica can start but does near to nothing. At prompt, all the commands produce this output:

super() takes at least 1 argument (0 given)
[<current directory>]

Ergonomica should either refuse to be installed in python 2 environment or be fixed for python 2 compatibility (I don't notice any statement about python compatibility in the documentation).

Works fine (ls produce a correct output) with a python 3 environment.

(version 2.0.5 installed in virtualenv environment)

This should do the most important changes for compatibility with prompt_toolkit 2.0, when this is released. This will also require ptpython 2.0 and pyvim 2.0 (both are also not yet released, but will be released together with prompt_toolkit 2.0).

In the meantime, it could be good to pin the version of both these dependencies on the 1.0 version, so that when prompt_toolkit 2.0 is released, we're not going to break stuff right away.

PEP8 compliance is a mixed bowl. People like Raymond Hettinger have often mentioned not only the futility of PEP8 adherence, and the fact that good code is not necessarily solely PEP8 compliant, but also the fact that PEP8 compliance can be a massive time drain, taking time away from more important tasks (writing unittests! resolving bugs and feature requests!). On the other hand, PEP8 compliance, especially partial compliance by configuration of a pylintrc, is a nice way of standardizing code style and making it easier to read, and also enforcing certain universal rules (e.g., docstrings for every function).

pacman acts strangely when invoking from ergonomica. For example, when running

sudo pacman -S noto-fonts-emoji

it first returns

[sudo] password for lschumm:

pacman is still functional (as in the package is installed, dependencies are properly resolved, etc.) but makes the interface less usable.

Currently Docopt is a buggy mess while the creator refuses to take any suggestions. Make a fork with a rewrite of the parser in PLY and various other features.

Proposal

Make Ergonomica stringly typed, like so:

set x 2
=> sets x to string 2
set x '2
=> sets x to number 2

Purpose

Currently, Ergonomica's namespace (being a Python dictionary) can accept any type of variables. However, given the fact that Ergonomica is stringly typed, you cannot set these outside of Python. This would allow this so the advantages of a typed language could be accessible in Ergonomica.

Feasability

Very Feasible; just use eval within the Ergonomica namespace.

Some files have pylint stuff, some don't, there's a lot of errors that are ignored in almost all files that should be put in a .pylintrc file. Do this and write a description of why the errors are ignored.

I use Click for all of my command-line stuff these days. Docopt is nice in that it's better than parsing the arguments manually, but Click is just a lot cleaner and allows for some cool verification functionality. Command-line usage specifications in text kind of adhere to a standard, but they're not as standardized and flexible as Click's decorator approach.

Writing this for the sake of documentation as well as refreshing my understanding:

• All Ergonomica commands are structured as individual files, with command-line argument handling. However, these are interpreted as Python files, and we peel out the functions so we can call them in the same Python interpreter (so we can pass Python data structures into them). We build up a namespace of these commands.
• When you call a command that is found in Ergonomica's library, we'll pretend it's being called from the command line, and thus utilize argument parsing/verification.

Hopefully Click will have some facilities with which I can more cleanly call Click-decorated functions from within Python, instead of needing to manipulate sys.argv.
