Handling dependencies

[klonuo]

pgcli running in Python 3.3. (This is the version of python shipped with Sublime Text 3). I recommend installing pgcli in a virtual environment.

Can you please elaborate how to use virtual environment in ST to meet requirements?

Assuming this would require installation of outdated Python 3.3, would you consider adding dependencies to your package, so that every single user doesn't have to?

Thanks

I fully admit it's a huge pain. The unfortunate reason it's necessary is that PgcliSublime depends on pgcli which in turn depends on psycopg2 to interact with postgresql. Sublime text ships with its own specific version of python (3.3), so in order to run pgcli inside of sublime text we need a specific version of psycopg2. Psycopg2 is a non-trivial binary dependency with a bunch of its own system dependencies and there's basically no way I could reliably package it. Ultimately the best way to go would be to split up pgcli into a server/client model so the pgcli server could run on a different version of python from the text editor client, but that's a huge amount of development work that isn't going to happen anytime soon.

So with all that said let me know what operating system you're using and I can try to help you set up a virtual environment

@darikg ok, thanks for your reply.

In the meantime I temporary installed Python 3.3 and created venv then pip installed pgcli. I copied pgcli and dependency modules, namely:

click\
pgcli\
pgspecial\
prompt_toolkit\
psycopg2\
pygments\
sqlparse\
wcwidth\

to ../Sublime Text/Data/Packages/pgcli/st3_windows_x64 and pointed pgclisublime to the location. Works nice.

So I have dependencies for 64 bit Windows, and if you wish to make a new repo for these (to cover your package) I can make PR for st3_windows_x64. If you can make this for Linux and/or OSX and PR to package control channel, then that would cover large base or users that wont need to install these dependencies manually.

[darikg]

Wow so pip actually installed psycopg2 for you? That's never worked for me on windows. I'm actually not sure what to do here. I'm pretty skeptical that this will work reliably and I don't have a lot of different machine configurations to test it on, or the time to do so. On the other hand I totally agree it would be nice to make the installation a lot easier for most people.

[klonuo]

:) Ok, np

Yep, psycopg2 in pypi for Python 3.3 comes as a wheel (with precompiled library)

[darikg]

Yup you're right, I just tried it and it installed painlessly. I'm wondering if instead of trying to package dependencies we just had a basic shell script that created a venv and installed via pip/conda

[klonuo]

Hm, I don't know about shell script. That would probably assume that user already has Python 3.3 installed or...?

I was thinking more about using ST dependency feature. I don't know if you have experience with that, but I'll try again:

1. You create a repo for dependencies. Here is example for lxml (https://github.com/eerohele/sublime-lxml)
2. You make PR from dependencies repo to package control channel
3. You add dependencies.json in this repo (PgcliSublime), i.e.:

{
    "*": {
        "*": [
            "pgcli"
        ]
    }
}

So I can push right now st3_windows_x64, and you or others can contribute for other platforms.

[darikg]

I'm coming around on this idea. I'm going to try to come back to it in the next couple weeks when I have some time to play around with it. Thanks for the links.

I believe i'm trouble shooting similar config issues on OSX. Let me know if you'd like me to test anything. Python 2.7.10 install on my machine.

Any news on this? Installing Python 3.3 just to make it work seems like overkill to me :(

I have similar issue on linux, sublime3 build 3143:

1) install PgcliSublime via Package Control 2) next go to console and set up virtualenv: cd ~/usr/ virtualenv-3.6 pgcli cd pgcli source ./bin/activate pip install pgcli 3) have virtualenv installed: pip freeze backports.csv==1.0.5 cli-helpers==0.2.3 click==6.7 configobj==5.0.6 humanize==0.5.1 pgcli==1.8.1 pgspecial==1.9.0 prompt-toolkit==1.0.15 psycopg2==2.7.3.2 Pygments==2.2.0 setproctitle==1.1.10 six==1.11.0 sqlparse==0.2.4 terminaltables==3.1.0 wcwidth==0.1.7
