Building Command Line Applications with Click

[@MoonStruckHorrorsX]

I usually can't watch programming tutorials but damn. This guy knows how to keep my attention.

[@tcarney57]

I love the simplicity of using the decorators you've provided. So much easier to use than argparse, and you get the help formatting features, too. Many thanks!

[@spaceyfounder5040]

I love your tempo! Straight to the problem, fast answers, upgrading the program by tiny steps. Yummy! ✓

[@gato_pardo]

Great video, quick and to the point!! A pleasure to watch.

[@DavideNastri]

Great work with Click, Armin! Thanks for taking the extra time in filming also this tutorial :)

[@QuintinMassey]

I want more! Thank you for recording this, the amount of examples available for Click are VERY scarce (especially video examples).

[@jacquev6]

Great tutorial, very interesting, thanks! I learned a lot and I'm looking forward to using Click.

[@zenahrb8316]

This was fantastic. Also your speed inspiring

[@omarcrosby]

Thanks for the video, definitely helped get me up to speed with click very quickly!

[@vadosware]

Great concise/clear video and guide. Love the tools you make, great work

[@MeirGabay]

i'm shocked that i have just watched the whole video, you explained it very well, thank you!

[@timalive1]

great outline! Thanks! One question, what do you use for your command line. love the info above your cursor.

[@maryannsalva3462]

Wow, this is what i need. Glad I found it! Thank you! 👍👍👍

[@mclrk]

I cannot find any documentation on how to use the "entry_points" feature of the setup.py file. Can you please direct me to the api documentation?

[@null1023]

That's really cool. It looks remarkably clean and easy to work with. a lot of little utilities I've done have kinda nasty argument handling, and this really seems like it'd clean things up

[@changyulin47]

save me hours of reading docs, thank you so much!

[@allbuzz]

This is a real quick help to get started with. Thankyou!!

[@entwine]

I was thinking to write a cli library in python with routing inspired by flask and then a week ago I discovered that Armin already did it. Thanks!

[@arnewiese]

Would you like to share your settings for vim and the osx terminal? :)

[@cztanu]

Great stuff. I should get back into using this library.

[@TravisHoglund]

What if you want a sub-command to be "account:login". How would you define that with click?

[@TravisHoglund]

Awesome Video, great job.

[@alexandrucheltuitor9525]

What about if I would like to use normal python params in conjunction with click params ? Let's say that I want to use the same function that I provide click.param, but in another piece of code I call that same function though provide another method (non click method), how could this be achieved ?

[@RoamingAdhocrat]

I love this, Arwid! Thanks. I'm new to Python so sorry if this is a daft question: is it possible/sensible to use Click to parse and dispatch commands entered into an Urwid text entry widget? Or would that be using a sledgehammer to hit a mallet to crack a nut?

[@YannSchmidt]

Impressive ! I was planning to use docopt but i prefer using click. Much more intuitive :) Thanks

[@DGDG0000000]

Thank you for this video. I just follow your way and pip install goes ok. But if i import a module from a package of !y own project directory, i get that, error: no commands supplied. If i do that from inside of a function (who is decorate by click.command), i also get an error and click doesn't works. It is unusable if people can no more import there own packages from there own project directory when they use Click. I think i missed an information... could you tell me ?

[@dominicnunes2709]

Is there anything like this for Ruby?

[@davidalexander8786]

thor and commander

[@Ucancallmemal]

please something else like this because this was awesome and useful!

[@조성민-y9n]

what's the font you are using?

[@JohnnyLeeOthon]

What kind of shell is that?

[@davidrsterry]

Great video. I hope you'll make more showing us more tricks with click. How about a series on pipsi as well?

[@MamboBean343]

+Armin Ronacher What shell do you use? zsh?

[@richerite]

Can someone give the python3 version of this example? I get errors when using the make_pass_decorator in py3

[@elachichai]

I don't get it. Is cli a keyword? why did we get error??

[@malayagr]

In the set-up file, you can see that he writes something like this: entry_points = ''' [console_scripts] hello = hello:cli This basically says that set hello as a command, corresponding to the hello.py script and the command should start execution from the function called cli in the script (hence, entry_points). Since there was no cli() function defined in the hello.py script, we got an error.

[@midinerd]

when installing the package with "pip install -e ." It will read setup.py and check in the entry_points=[] info hello_output = hello_codefile:cli is read as: "Create an entrypoint: hello_output.exe #I'm on windows hello_output.exe will consume hello_codefile.py and execute cli()" hello_output.exe won't be created until you run: "pip install -e ." It will be in dist/hello_output.exe In this example case it is: hello.exe is created, reads from hello.py, and runs cli() Also means you can 'install' this and create the hello_output.exe executable once, and then you can edit hello_codefile.py and re-run hello_output.exe to observe changed behavior without needing to rebuild hello_output.exe cheers

[@ДаниилПрохоров-ю4й]

Wow. Top video!

[@abhishekkalia2702]

This is the author of the flask framework. Why are the comments so ungrateful ?

[@RajKumarSingh-xt1pq]

why dont you upload complete tutorial series?? it would be of great help dude!

[@alice_in_wonderland42]

why can't you read the complete documentation?? it will help you.

[@EViL3666]

@@alice_in_wonderland42 Some people finding video based tutorials easier to follow. I sympathise with the OP, I see potential of Click, but his usage of setuptools is confusing (no, its not something I'm familiar with)

[@alice_in_wonderland42]

@@EViL3666 for most of the libraries u don't have any video tutorials, but they have great documentation.

[@EViL3666]

@@alice_in_wonderland42 Very true.

[@tcarney57]

@@EViL3666 I think Armin could have left out the setuptools part. Some people begin a project that way. I'm sure there's an argument for doing so, but I can't be bothered. If you're not going to "ship" the app, I don't see the point.

[@KonstantinDorichev]

Very helful. Thanks a lot!

[@elachichai]

what is your PS1?

[@PGhai]

Thanks for creating this video

[@bendover4728]

Beautiful!

[@DJ-op6jt]

Hey thanks, just the info i needed !!

[@Mid.G.]

Using click right now for the first time and its awesome! So is Flask, so is Jinja, so is whatever you're working on next :D. Quick question -- can you upload your .bashrc somewhere? I'm really digging the prompt.

[@ripnlip33]

Your zsh config is nice. Could you send me your .zshrc? If not, what's the theme and how did you get the workon "virtualenv"? Thanks for the tutorial

[@peteroliver6670]

I just find you now guy amazing tool to use in terminal

[@peiquedq]

Very nice, thank you very much :)

[@AndrewRodgers]

Thanks, somehow click didn't click until watching this.

[@jpaldama9963]

Do you have a email of a way I can contact you? python advice? pay?

[@arjhuns9072]

If y'all didn't know, he created the library lol

[@vatsalaykhobragade]

He created Flask.

[@sdelquin]

Useful lib! Thanks for that. Just offtopic: could you post your .vimrc and $PS1?? They look great!

[@shipeng3923]

So cool

[@elachichai]

looks like you are showing off your vi editor skills than tutor click

[@andrewsanchez5895]

If he was showing of he wouldn't have quit vim every time he wanted to run a shell command ;) :! hello

[@memoriasIT]

Andrew Sanchez I didn’t know that, thanks bro

[@timetraveller3647]

pretty sure there was much more to learn but you couldn't look past the editor

[@smitty1e]

Spacemacs.org

[@scriptingtips596]

It should be taken as a compliment: if you think he is showing that's because you're impressed with his skills :-) But vim wizards do not use their mouse. I'm 0:52secs into the video and the author is already moving his mouse everywhere.

[@thestarlightvarietyshow9303]

watched this and was like, wow, he seems like a pretty good programmer. Or perhaps he's just mediocre by most standards and I'm a bad programmer. Later I found out he invented flask-restless and now I feel better about myself :)

[@sorvex9]

Yeah I also felt pretty bad about my programming skills watching this.

[@kebabimpaler]

Sold

[@jessw4195]

Great video but slowing down would have been nice. No need to go at the speed of light there.

[@lamnguyentrong275]

nice, but next time could u speak louder please, the audio kinda small

[@lohannasarah5054]

thanks!!!

[@__se7entin__]

Damn are you typing with your mind 😅

[@unique1o1-g5h]

i thought i was watching this video at 1.5X but it was 1.0X

[@elachichai]

do you have something visual to understand calls instead of so much textual explanation? please keep in mind you are not explaining to pros.

[@carlfranz6805]

Talks fast, not enough pictures...

[@pratsbhatt]

Way to fast.. Are you trying to catch a bus?

[@DavideNastri]

I think this is the pace of his thinking :) Thank god we can replay it or pause it.

[@pawel7318]

I like the tempo. hint: YT allows you to set different speed of the playback - check the settings

[@imxron]

too*

[@louisburke8927]

The sound of your keyboard is extremely annoying.

[@JamesOShaughnessy]

Whats click?

[@louisburke8927]

It's a framework for building command line interfaces

[@redstoneisawesome9336]

+Louis Burke It's probably just me, being wierd, but for some reason I like the sound of people typing... Please don't scream at me I'm not trying to sound ignorant, disrespectful etc.

You are not a great teacher!! Are you trying to show us how good you are?

[@andrewsanchez5895]

I thought the video was excellent. A great student will learn even when the teacher doesn't fulfill their desires :)

Did you consider you might not be a very good student.
