sorno-py-scripts 0.34.0

Herman Tai's python scripts all prefixed with "sorno_"

My python scripts. sorno is just a brand name that I use for my stuff. It’s convenient to use that as a package name instead of the usual “org.xxx”.

The source code of the whole project is in github: https://github.com/hermantai/sorno-py-scripts

PyPI page: https://pypi.python.org/pypi/sorno-py-scripts

All scripts support the “-h” or the “–help” option for documentation of the scripts. Often the documentation is in the __doc__ of the script, so take a look at that as well.

All scripts are prefixed with “sorno_” to avoid polluting the Scripts folder (in Windows, /usr/local/bin in *nix) of python or other binaries when this suite is installed.

This project also includes the sorno library.

Installation

If you don’t have Python installed, you first need to install it from https://www.python.org/downloads/. You need a version at least 2.7 but lower than 3.0.

For the following commands, add sudo in front of the commands if you are getting permission error.

A Python package management system will make your life easier, so install pip by:

$ easy_install pip

If easy_install is not on your system, you can check how to install it in https://pythonhosted.org/setuptools/easy_install.html#installing-easy-install.

Install with pip

$ pip install sorno_py_scripts  # note that the project name is in underscores, not dashes

Install with easy-install

$ easy_install sorno_py_scripts  # note that the project name is in underscores, not dashes

Install from source

You can install sorno-py-scripts from the source code by cloning the git repo:

$ git clone https://github.com/hermantai/sorno-py-scripts

Then cd to the sorno-py-scripts directory:

$ cd sorno-py-scripts

Install it:

$ python setup.py install

Running the scripts

Your scripts should be installed at your $PATH. For nix system, they are usually in */usr/local/bin. For windows, they should be in a Scripts directory under the Python installation.

Make sure your scripts are in the PATH system environment variables.

Then you can run the scripts by simply invoking them from the command line console ($ is the prompt of the console):

$ sorno_gtasks.py -h

Running the tests

In the directory containing the ./test.sh file, then run it:

$ ./test.sh

You can run tests only for the sorno library:

$ ./test_sorno.sh

Or tests only for the scripts:

$ ./test_scripts.sh

Contents

Use -h or –help options for the scripts to get more detail documentation for each script.

sorno_alarm.py (alpha)

A console alarm which uses the system bell as the alarm bell by default. You set how many seconds before the alarm goes off, not an absolute time in the future. After you respond to the bell (e.g. please “Enter” in the console after the system bell rings), it restarts the alarm and will ring again after your specified time. Use control-c to exit the alarm completely.

sorno_amazon_reviews_scrape.py

A script to scrape Amazon product reviews from the web page.

sorno_amazon_wishlist_scrape.py

A script to scrape items from an Amazon wishlist. The script only works for wishlists which are “Public”. You can change the settings by following the instruction in: http://www.amazon.com/gp/help/customer/display.html?nodeId=501094

sorno_appcache_generator.py

Generate an appcache file to be used for html5 application cache of a web application. The goal is to make the whole web app cached, so the app can be run offline.

sorno_attach_realdate.py

Attaches the actual time in human readable format for timestamps found in coming lines.

Example:

$ cat /tmp/abc
once upon a time 1455225387 there is
1455225387 something called blah
and 1455225387
then foo

$ cat /tmp/abc |python scripts/sorno_attach_realdate.py
once upon a time 1455225387(2016-02-11 13:16:27) there is
1455225387(2016-02-11 13:16:27) something called blah
and 1455225387(2016-02-11 13:16:27)
then foo

sorno_cloud_vision.py

sorno_cloud_vision.py makes using the Google Cloud Vision API easier.

Doc: https://cloud.google.com/vision/docs

The script generates requests for the given photos, sends the requests to Cloud Vision, then puts the results into the corresponding response files.

sorno_compress_photos.py

Compresses all photos in a directory to jpg quality.

sorno_download_all.py

Downloads all items from all links from a URL.

sorno_dropbox.py

Provides utilities to work with dropbox just like the official dropbox cli (http://www.dropboxwiki.com/tips-and-tricks/using-the-official-dropbox-command-line-interface-cli), but in a script instead of a REPL way. sorno_dropbox also has higher level features like copying directories recursively.

sorno_email.py

Sends a simple email with plain text

The script first tries to use your system Mail Transfer Agent(MTA) configured, otherwise, it prompts for login to use Gmail SMTP server.

sorno_facts.py

Prints out a random fact for fun

sorno_gdoc.py

A command line client for accessing Google Docs. The API doc used to implement it is in https://developers.google.com/drive/web/quickstart/quickstart-python

You can search for a file and download its content (only if it’s a doc).

sorno_gdrive.py

A command line client for Google Drive. The API doc used to implement this is in https://developers.google.com/drive/web/quickstart/quickstart-python

Currently, you can upload files with the script.

sorno_grepchunks.py

Oftenly, you want to treat multiple lines as one chunk and see if it matches a regex. If it does, you want to print out the whole chunk instead of the only line that matches the regex. sorno_grepchunks lets you define what a chunk is by giving a chunk starting regex, that is, all the lines starting from the line that matches the regex and before the next match are treated as one chunk. You can then apply another regex to match against it.

sorno_gtasks.py

A script version of Google Tasks

sorno_ls.py

sorno_ls.py is just like the Unix “ls” command

sorno_pick.py

A script to prompt for choosing items generated from different sources, then print those items out. For example, if you have a script to generate common directories that you use, e.g. gen-fav-dir.sh, you can put the following in your .bashrc, assuming sorno_pick.py and gen-fav-dir.sh are in your PATH:

$ alias cdf='cd $(sorno_pick.py -c gen-fav-dir.sh)'

Then you can just type:

$ cdf

And you will be given a list of directories to “cd” to.

P.S. You probably want to set the alias to the following:

$ alias cdf='tmp="cd $(sorno_pick.py -c gen-fav-dir.sh)";history -s "$tmp";$tmp'

This ensures the history is inserted in a useful way, e.g. when you run “history”, you see the actual command instead of just “cdf”.

sorno_podcast_downloader.py

Downloads podcasts given a feed url.

The downloaded podcasts have useful file names (e.g contain the title of the podcast and prefixed by the published date).

sorno_protobuf_to_dict.py

Converts text format of protobufs to python dict.

The script launches ipython for you to play with the parsed python dict.

sorno_realdate.py

Prints the human readable date for timestamps

Example:

$ sorno_realdate.py 1455223642 1455223642000 1455223642000000 1455223642000000000
1455223642: 2016-02-11 12:47:22-0800 PST in s
1455223642000: 2016-02-11 12:47:22-0800 PST in ms

1455223642000000000: 2016-02-11 12:47:22-0800 PST in ns

sorno_reduce_image_sizes.py

Saves images with reduced sizes.

Reduces the sizes of all images in a directory and its subdirectories by saving them with lower quality jpg format. The directory structure is preserved but the new directory is created with a timestamp suffix.

sorno_rename.py

sorno_rename.py renames files given regex for matching names of the existing files and using backreferences for filenames to be renamed to.

sorno_replace_thrift_const.py

Replaces constants with literal values for a thrift file except for the declaration. This is mainly for thrift compilers which cannot handle constants within lists or other collection structures.

sorno_scrape_peg_list_1000.py

Scrapes the 1000 pegs from http://www.rememberg.com/Peg-list-1000/

sorno_spacefill.py

Fills up the disk space with a specific size of garbage data.

sorno_stock_quote.py

Gets stock quotes and other information for stock symbols.

The script can print real-time or close to real-time stock quotes, historical quotes, and also fundamental ratios for the stock (company).

sorno_summarize_code.py

Prints a summary of the code file.

It makes the layout of the code to be read easily. Currently it only supports python files.

sorno_top_size_files.py

Prints the top files in terms of sizes.

Prints the top files in terms of sizes under a directory or its subdirectories size

Using scripts involving Google App API

For scripts like “sorno_gdoc.py”, “sorno_gdrive.py” and “sorno_gtasks.py”, a Google App project is required to account for the quota of using the API. You need to get an OAuth2 client id and secret for your Google App project, then export them as environment variables “GOOGLE_APP_PROJECT_CLIENT_ID” and “GOOGLE_APP_PROJECT_CLIENT_SECRET” respectively (replace “xxx” and “yyy” with your actual values) before running the script:

export GOOGLE_APP_PROJECT_CLIENT_ID='xxx'
export GOOGLE_APP_PROJECT_CLIENT_SECRET='yyy'

You probably want to put the two lines above in your bashrc file.

You can get the oauth2 client id and secret by the following steps:

1. Choose a Google App project or create a new one in https://console.developers.google.com/project

2. After you have chosen a Google App Project, you then go to the tab “APIs & auth” on the left.

3. Click on the APIs subtab, and search for the API needed for the script you want to use. The help page of the script tells you what API your project needs. For example, sorno_gtasks.py needs the Tasks API with the scope ‘https://www.googleapis.com/auth/tasks’. Enable it.

4. Go to the “Credentials” subtab, click “Add credentials”, choose “OAuth 2.0 client ID”, enter some information on the OAuth consent screen if prompted. In that screen, only email address and product name are required to be filled out. For the Application type, choose “Other”.

5. After the credentials is created, click on it and you should see your Client ID and Client secret there.

Troubleshooting

If you are getting some import error when running the script, make sure you have the newest Google API Client Library for Python. You can find the installation instruction here: https://developers.google.com/api-client-library/python/start/installation

Development

Start

A sample of a script can be obtained from python/script_template.py in https://github.com/hermantai/samples.

Unit testing

You can run the unit tests in the scripts/tests directory. First, set up the testing environment by running:

$ source setup_test_env.sh

If you have installed sorno-py-scripts in your machine, the sorno library from the installation is used instead of your local changes because of easy-install messing with the search path. In that case you need to either remove the egg manually or bump up the version and install it with your local changes to override the existing version.

Then you can run individual unit tests with:

$ python scripts/tests/test_xxx.py

Deployment

The only deployment destinations for now is github and PyPI. In github, this project resides in the sorno-py-scripts project: https://github.com/hermantai/sorno-py-scripts

To deploy to PyPI, first install twine:

$ pip install twine

Then you can use the script to deploy to PyPI:

$ ./pypi_deploy_with_twine.sh

Use sudo if you encounter permission issues when running the commands.

Use the following if you get an error saying “twine cannot be found” even twine is on your PATH:

sudo env "PATH=$PATH" ./pypi_deploy_with_twine.sh

If twine does not work, use the old school:

$ ./pypi_deploy.sh
