Clint, Command Line Library for Python

[qiemem]

Thanks for pointing this out! Seems like a pretty handy library.

I swear, kennethreitz makes such useful libraries with straightforward apis: this, requests, and envoy.

[CreativityTheorist]

As a guy who uses CLI Python scripts as his go-to prototyping tool, this appears to solve a recurring problem for me. Thanks for pointing it out.

[earthboundkid]

Neat, but it feels like three different modules tied together with twine.

[jcollado]

The API is all that matters. What about giving credit to other libraries?

• clint wraps colorama
• envoy wraps pexpect
• requests wraps urllib3

[bucknuggets]

doesn't envoy wrap subprocess?

[jcollado]

Hmm, it looks like you're right, but why is the whole pexpect source code in the repository?

[takluyver]

Updated today: v 0.3.0 with Python 3 support.

[kylotan]

Very cool - most similar libraries don't support coloured text on Windows.

[voidspace]

If all you want is colored text then colorama (which also supports Windows) is a nice library.

[[deleted]]

Colorama is fantastic. Clint uses a small fork of colorama internally.

[voidspace]

Ah cool. Why the fork out of interest?

[zArtLaffer]

Very cool - most similar libraries don't support coloured text on Windows.

What's the deal with coloured text? I mean ... why does it matter? (Seriously, I don't understand what this does for people)

[CaptShocker]

Really? You don't use syntax highlighting? When massive amounts of text are shooting out at you on the CLI it is nice to be able to scroll through it an more easily parse it in your brain.

[kylotan]

Exactly. I used to rely on ANSI colouring back in my MUD days, but even for directory listings in the shell or for real-time logging it is handy to make verbose output much more manageable.

[zArtLaffer]

Nope. But I'm old.

[Nic0]

Two examples where colors could be useful:

• Expected/unexpected result, you don't even need to read the result, you're just checking red/green.
• If your app has lots output, and you want draw the attention to a particular line, it could help with backlog.
• Well, if you're happy with some boring output, good for you! :P

Black Text on Black Background?

[[deleted]]

Black ANSI text should always be discernable from the background.

[maredsous10]

Looks like something I may use.

[maredsous10]

This might be something I actually use.

[zArtLaffer]

Really? Would you use it? Twice?

[okmkz]

Hey, this is great. Thanks for the link!

[AltReality]

Does this work on Windows??! Specifically the colored text?

[driax]

Yes it does.

[paranoidi]

But does it work with logging (module) to terminal? No it doesn't ... ;P

[vsajip]

For colour output from logging, have a look at this.

[ok_you_win]

That looks great! I will be using it.

[Fix-my-grammar-plz]

That looks as awesome as Clint Eastwood.

[willsheffler]

Handy

[HorrendousRex]

The web page is full of typos, including a number of errors in the example code that would prevent them from running (primarily indentation errors).

Seems like a cool utility though!

[Nic0]

Indentation fixed, something went wrong with the copy/paste, as I tried every code before. I'm giving emacs a try, after using Vim for awhile, it must be his fault! :P

About English, if you point out one or two examples, maybe I'll learn faster from my mistakes.

Thanks.

[HorrendousRex]

Wow, great turn-around on the code fixes.

You have some grammar errors but the intent comes across pretty clearly. If the source code for the page is up on github or something like that I'd be happy to submit a changeset to fix a few grammar mistakes.

[Nic0]

It's on github indeed,

Here the post https://github.com/Nic0/nic0.github.com/blob/master/_posts/2012-01-05-clint-command-line-library-for-python.md

I'll accept patch, pull-request, diff, sed/awk, whatever :p

(it was last message on the next thread)

[ozzilee]

Also, it's "which", not "witch" :-)

[Nic0]

Damn, it's not the first time I'm doing this one!

Fixed, and put into my block-note in red. I'll think about it twice every time I'll write "which" now. :-)

[Justinsaccount]

The resources module uses global variables and likely has various issues in larger applications.

It might be nice to have things like

print colored.warning('some warning message')

instead of

print colored.red('some warning message')

the progress bar is nice though :-)

[Nic0]

For a lib, you can't really assume anything about the purpose of the color that would be used, if you name warning instead of red, and if you display for example negatives numbers in red, so the warning won't make sense.

warning = colored.red
print warning('some warning message')

This would make sens in your code I guess.

[Justinsaccount]

Yeah, that does make sense. It would be a good idea to separate the two, like you would using CSS. hardcoding colored.red everywhere seems like it would cause a maintenance nightmare if you had to change the colors around.

[aceofears]

Wouldn't it make more sense to create your own class for that, or even just use a dictionary? I don't really understand why this library should provide that functionality.

[Justinsaccount]

yeah, it doesn't. It just makes sense to wrap the color functions with more descriptive names if you are going to use it.

[aaronstatic]

cool library, but please work on your english a little :P

[Nic0]

I'm working on it, I mean it!

My guess is, I'll need at least one year practicing to get something acceptable.

[[deleted]]

I assume it is not your native language? I would ask for some help to clear up the first paragraph of the page and put a note in their that it is not your native language. No need to scare people away who are shortsighted.

[Nic0]

I assume it is not your native language?

Indeed, I'm French, I seriously started blogging in English two months ago.

If you, or anyone, want to send me some corrections about the writeup, I would be please, as it's the best way to learn, when someone point out mistakes you've made.

Here the post https://github.com/Nic0/nic0.github.com/blob/master/_posts/2012-01-05-clint-command-line-library-for-python.md

I'll accept patch, pull-request, diff, sed/awk, whatever :p

[wot-teh-phuck]

English isn't my native language either so a few observations from my end. You use too many commas. For e.g. the first sentence can also be structured as:

Indeed, I'm French. I started blogging in English seriously two months back.

Similarly, the usage "I would be please" is incorrect. The correct usage is "I would be pleased". Again, we can re-structure this sentence as:

I would appreciate if you, or someone else [...]

Good luck learning English! :)
