if you ever find yourself in the position I’m in rn – having somehow managed to forget to make an important call *all day* – just a reminder that it’s actually incredibly easy to schedule an iPhone telephone call that will happen without any user intervention lol.
Today, Tumblr is accessible via mobile, web or apiโbut what if youโre a linux enthusiast? Nerds like you can now access Tumblr completely via command line.
โWhat about images?โ you ask. Displaying an image in command line is not something new. There are already a bunch of existing libs doing this, namely aalib, libcaca and super low level ncurses. And the most interesting project built based on thoseโp2p video chatโcomes from a hackathon.
I picked up a much higher level library called blessed, for least efforts to achieve a best looking interface. As you may seen, blessed is javascript-based and very fancy. It provides you with almost every widget you might need to build an awesome dashboard.
Most of the work has already been done after figuring out the right library, to show tumblr in command line, we just need to
Connect the api to fetch image urls.
Do some front-end design to show a Tumblrish dashboard.
What? Still need codes?โฆ
var post = blessed.box({
parent: dashboard,
top: '15%',
left: 'center',
width: '40%',
height: '80%',
draggable: true,
border: {
type: 'line'
},
style: {
fg: 'white',
bg: 'white',
border: {
fg: '#f0f0f0'
}
},
});
var load_post = function() {
if (index < 0 || index >= posts.length)
return;
post.free();
var post_data = posts[index];
/** avator */
blessed.ANSIImage({
parent: post,
top: 0,
left: '-30%',
width: '20%',
height: '20%',
file: post_data.avator,
});
/** posts */
var count = post_data.count;
// TODO: switch all sizes
for (var i = 0; i < count; i++) {
var offset = 100/count * i;
var width = 100/count;
blessed.ANSIImage({
parent: post,
left: offset + '%',
width: width + '%',
height: '98%',
file: post_data.data[i]
});
}
screen.render();
}
Blessed already provided lots of high level apis. As an example, to display a post as an image, all your input is just an image url, and call
It supports png and gif, and even, if youโd like to show a video, blessed also provides video. Hypothetically speaking, we can use this library to build almost all components in the dashboard of Tumblr today. Note, itโs not connecting the real api, but I suppose that would be pretty easy. Also thereโs a memory optimization issue might need to be addressed if we really want to use this library for something.
We just published v1.1.0 of the tumblr.js API client. We didnโt make too much of a fuss when we released a bigger update in May, but hereโs a quick run-down of the bigger updates you may have missed if you havenโt looked at the JS client in a while:
Method names on the API are named more consistently. For example, blogInfo and blogPosts and blogFollowers rather than blogInfo and posts and followers.
Customizable API baseUrl. We use this internally when weโre testing new API features during development, and itโs super convenient.
data64 support, which is handy for those times when you have a base64-encoded image just lying around and you want to post it to Tumblr.
Support for Promise objects. Itโs way more convenient, if you ask me. Regular callbacks are still supported too.
Linting! Weโve been using eslint internally for a while, so we decided to go for it here too. Weโre linting in addition to running mocha tests on pull requests.
Check it out on GitHub and/or npm and star it, if you feel so inclined.
tumblr.js REPL
When we were updating the API client, we were pleasantly suprised to discover a REPL in the codebase. If you donโt know, thatโs basically a command-line console that you can use to make API requests and examine the responses. We dusted it off and decided to give it its own repository. Itโs also on npm.
If youโre interested in exploring the Tumblr API, but donโt have a particular project in mind yet, itโs a great way to get your feet wet. Try it out!
How to Update all Python Packages with a Single pipย Command
ALT
Ensure all present Python packages on Windows and Linux systems are parallel with their latest available versions from the command line.
With Python, the best practice of pinning all the packages in an environment at a specific version ensures that the environment can be reproduced months or even years later.
Pinned packages in a requirements.txt file are denoted by ==. For example, requests==2.21.0. Pinned packages should never be updated except for a very good reason, such as to fix a critical bug or vulnerability.
Conversely, unpinned packages are typically denoted by >=, which indicates that the package can be replaced by a later version. Unpinned packages are more common in development environments, where the latest version can offer bug fixes, security patches and even new functionality.
As packages age, many of them are likely to have vulnerabilities and bugs logged against them. In order to maintain the security and performance of your application, youโll need to update these packages to a newer version that fixes the issue.
The pip package manager can be used to update one or more packages system-wide. However, if your deployment is located in a virtual environment, you should use the Pipenv package manager to update all Python packages.
NOTE: be aware that upgrading packages can break your environment by installing incompatible dependencies. This is because pip and pipenv do not resolve dependencies.
Python Package Upgrade Checklist
In general, you can use the following steps to perform a package upgrade:
Check that Python is installed
Before packages can be updated, ensure that a Python installation containing the necessary files needed for updating packages is in place by following the steps outlined in “[Using Python on Windows]” in the official documentation.
Get a list of all the outdated packages
To generate a list of all outdated packages:
pip list –outdated
Upgrade outdated packages
Depending on your operating system or virtual environment, refer to the following sections.
The easiest way to update all packages in a Windows environment is to use pip in conjunction with Windows PowerShell:
Open a command shell by typing powershell in the Search Box of the Task bar
Pip can be used to upgrade all packages on either Windows or Linux:
Output a list of installed packages into a requirements file (requirements.txt):
pip freeze > requirements.txt
Edit requirements.txt, and replace all == with >=. Use the Replace All command in the editor.
Upgrade all outdated packages:
pip install -r requirements.txt –upgrade
Updating all Packages in a Virtual Environment
The easiest way to update unpinned packages (i.e., packages that do not require a specific version) in a virtual environment is to run the following Python script that makes use of pip:
import pkg_resources from subprocess import call for dist in pkg_resources.working_set: call(“python -m pip install –upgrade ” + dist.<projectname>, shell=True)
Updating all Packages in a Pipenv Environment
The simplest way to update all the unpinned packages in a specific virtual environment created with pipenv is to do the following steps:
Activate the Pipenv shell that contains the packages to be upgraded:
Here is something Iโve been working on for quite a while now. I first had the idea for this when I went to Vienna. I was annoyed that Apple still didnโt allow TextExpander to do what I love it to do. Three weeks ago it looked bad for TextExpander already, now, a couple of weeks later, it looks even worse.
Since Mavericks, Text Shortcuts (System Preferences โ Keyboard โ Text) sync with iOS devices. I started thinking how to automate adding new shortcuts by script. Scripting the UI is, obviously and technically, my least favorite option, but itโs what I ended up doing.
If you are interested in the technical difficulties that I had to overcome, which make this script work the way it does, read on. Otherwise head to the end to download.
How OS X Text Shortcuts Work
When a new Text Shortcut gets added in the System Preference pane Keyboard โ Text, OS X does a couple of things.
First it saves a โreceiptโ of this addition/removal to ~/Library/Mobile Documents/com~apple~TextInput/ in there are a couple of folders. Most important are those with your username. Open that folder and you see UserDictionary with a subfolder. Select the ones with โ~โ in their name.
Every time you add or remove a new shortcut a zipped plist will be saved here, containing an Epoch timestamp, the shortcut and the phrase (as Apple calls expansions). Some other data is in the plist as well, but the important bits are the ones I just described.
The other important folder is in ~/Library/Dictionaries/CoreDataUbiquitySupport. This folder looks similar. It contains two folders, somewhere you will find a UserDictionary.db file. This is a SQLite database.
When a new shortcut gets added, a new row will be created here. Again Epoch timestamp, shortcut, and phrase are the important pieces.
What Does Not Work
My first guess was to add new โreceiptโ files to Mobile Documents. I was hoping that OS X would realize thereโs a new file, read it and add it to OS X Text Shortcuts, and that this would also transfer new shortcuts to an iOS device. It does not.
Adding new files here with a similar structure does not update the System Preference pane Table View, nor does it make an iOS device recognize the addition.
I started tinkering with SQLite then. The SQLite database in Dictionaries is only used to feed the Table View displayed in System Preferences. Add new rows here with a similar structure, restart System Preferences, and you will see the new shortcut. Editing the database files does not trigger iCloud to sync shortcuts.
At this point I was pretty disappointed and took my least favorite route, UI scripting. I know itโs hacky, I know itโs dirty, I know all that, but scripting the UI lead to a working solution.
Maybe looking a bit more into Mobile Documents would eventually have resulted in a better solution. I weighed the time it would take me to figure this out against the time it takes me to make a first running version. I prefer things to be done.
How This Script Works
PLEASE READ THIS, IT IS IMPORTANT! ALL YOUR EXISTING SHORTCUTS WILL GO POOF!
Open System Preferences โ Keyboard โ Text
Click the Table View, select all, press backspace. This deletes all existing shortcuts and takes a moment or two.
Turn off TextExpander text expansion. This is important. Otherwise when the script types the phrase, TextExpander would expand the abbreviation.
It will then compile a list of all your TextExpander snippets.
The script will then click +, type out the abbreviation, โฅ to the next cell, paste the expansion from the clipboard, press return.
After it has completed typing all shortcuts, TextExpander text expansion will be turned back on.
A few things to note:
As the script automates the UI, just sit and watch. It takes about 4:40 minutes to type in about 300 snippets.
The clipboard is used, because this way the expansion can have multiple lines.
This script is smart enough not to process any dynamic snippets. Dynamic snippets use date calculations, Fill-Ins, and any script snippets.
It takes a while for the list of snippets to be compiled. If AppleScript Editor says โRunningโฆโ at the bottom, the script is still running.
If you hear an error beep you may have luck running the script again. Sorry this happens sometimes, I couldnโt figure out why.
Set all snippet groups that you donโt want to be added in disallowedGroups. The name must match the snippet groupโs name.
If you want to know how many snippets you have, comment out the part where the script starts adding all Text Shortcuts. There is a line
log "Count of abbreviationList: " & (count of abbreviationList)
