A webmining CLI tool & library for python.
Project description
minet is a webmining CLI tool & library for python. It adopts a lo-fi approach to various webmining problems by letting you perform a variety of actions from the comfort of your command line. No database needed: raw data files will get you going.
In addition, minet also exposes its high-level programmatic interface as a library so you can tweak its behavior at will.
Features
- Multithreaded, memory-efficient fetching from the web.
- Multiprocessed raw text content extraction from HTML pages.
- Multiprocessed scraping from HTML pages using a comfy JSON DSL.
- URL-related heuristics utilities such as normalization and matching.
- Data collection from various APIs such as CrowdTangle.
Installation
minet can be installed using pip:
pip install minet

If you need help about a command, don't hesitate to use the -h/--help flag or the help command:
minet ct posts -h
# or:
minet ct posts --help
# or
minet help ct posts
To check the installed version of minet, you can use the --version flag:

fetch
usage: minet fetch [-h] [--compress] [--contents-in-report] [-d OUTPUT_DIR]
[-f FILENAME] [--filename-template FILENAME_TEMPLATE]
[-g {firefox,chrome}] [-H HEADERS] [--resume]
[--standardize-encoding] [-o OUTPUT] [-s SELECT] [-t THREADS]

column [file]
Minet Fetch Command
===================
Use multiple threads to fetch batches of urls from a CSV file. The
command outputs a CSV report with additional metadata about the
HTTP calls and will generally write the retrieved files in a folder
given by the user.
positional arguments:
column Column of the CSV file containing urls to fetch.
file CSV file containing the urls to fetch.
optional arguments:
-h, --help show this help message and exit
--compress Whether to compress the contents.
--contents-in-report, --no-contents-in-report Whether to include retrieved contents, e.g. html, directly in the report
and avoid writing them in a separate folder. This requires to standardize
encoding and won't work on binary formats.
-d OUTPUT_DIR, --output-dir OUTPUT_DIR Directory where the fetched files will be written. Defaults to "content".
-f FILENAME, --filename FILENAME Name of the column used to build retrieved file names. Defaults to an uuid v4 with correct extension.
--filename-template FILENAME_TEMPLATE A template for the name of the fetched files.
-g {firefox,chrome}, --grab-cookies {firefox,chrome}
Whether to attempt to grab cookies from your computer's browser.
-H HEADERS, --header HEADERS Custom headers used with every requests.
--resume Whether to resume from an aborted report.
--standardize-encoding Whether to systematically convert retrieved text to UTF-8.
-o OUTPUT, --output OUTPUT Path to the output report file. By default, the report will be printed to stdout.
-s SELECT, --select SELECT Columns to include in report (separated by `,`).
-t THREADS, --threads THREADS Number of threads to use. Defaults to 25.
--throttle THROTTLE Time to wait - in seconds - between 2 calls to the same domain. Defaults to 0.2.
--total TOTAL Total number of lines in CSV file. Necessary if you want to display a finite progress indicator.
--url-template URL_TEMPLATE A template for the urls to fetch. Handy e.g. if you need to build urls from ids etc.
-X METHOD, --request METHOD The http method to use. Will default to GET.
examples:
. Fetching a batch of url from existing CSV file:
`minet fetch url_column file.csv > report.csv`
. CSV input from stdin:
`xsv select url_column file.csv | minet fetch url_column > report.csv`
. Fetching a single url, useful to pipe into `minet scrape`:
`minet fetch http://google.com | minet scrape ./scrape.json > scraped.csv`
extract
If you want to be able to use the extract command, you will need to install the dragnet library. Because it is a bit cumbersome to install, it's not included in minet's dependencies yet.
Just run the following & in the same order (dragnet needs to have specific deps installed before it can be able to compile its native files):
pip install lxml numpy Cython
pip install dragnet
usage: minet extract [-h] [-e {dragnet,html2text}] [-i INPUT_DIRECTORY]
[-o OUTPUT] [-p PROCESSES] [-s SELECT] [--total TOTAL]
[report]
Minet Extract Command
=====================
Use multiple processes to extract raw text from a batch of HTML files.
This command can either work on a `minet fetch` report or on a bunch
of files. It will output an augmented report with the extracted text.
positional arguments:
report Input CSV fetch action report file.
optional arguments:
-h, --help show this help message and exit
-e {dragnet,html2text}, --extractor {dragnet,html2text}

-i INPUT_DIRECTORY, --input-directory INPUT_DIRECTORY
Directory where the HTML files are stored. Defaults to "content".
-o OUTPUT, --output OUTPUT Path to the output report file. By default, the report will be printed to stdout.
-p PROCESSES, --processes PROCESSES Number of processes to use. Defaults to 4.
-s SELECT, --select SELECT Columns to include in report (separated by `,`).
--total TOTAL Total number of HTML documents. Necessary if you want to display a finite progress indicator.
examples:
. Extracting raw text from a `minet fetch` report:
`minet extract report.csv > extracted.csv`
. Working on a report from stdin:
`minet fetch url_column file.csv | minet extract > extracted.csv`
. Extracting raw text from a bunch of files:
`minet extract --glob "./content/*.html" > extracted.csv`

API
multithreaded_fetch
Function fetching urls in a multithreaded fashion.
from minet import multithreaded_fetch
# Most basic usage
urls = ['https://google.com', 'https://twitter.com']
for result in multithreaded_fetch(urls):
print(result.url, result.response.status)
# Using a list of dicts
urls = [
{
'url': 'https://google.com',
'label': 'Google'
},
{
'url': 'https://twitter.com',
'label': 'Twitter'
}
]
for result in multithreaded_fetch(urls, key=lambda x: x['url']):
print(result.item['label'], result.response.status)
Arguments:
- iterator iterable: An iterator over urls or arbitrary items, if you provide a
keyargument along with it. - key ?callable: A function extracting the url to fetch from the items yielded by the provided iterator.
- request_args ?callable: A function returning arguments to pass to the internal
requesthelper for a call. - threads ?int [
25]: Number of threads to use. - throttle ?float|callable [
0.2]: Per-domain throttle in seconds. Or a function taking the domain and current item and returning the throttle to apply. - guess_extension ?bool [
True]: Whether to attempt to guess the resource's extension. - guess_encoding ?bool [
True]: Whether to attempt to guess the resource's encoding. - buffer_size ?int [
25]: Max number of items per domain to enqueue into memory in hope of finding a new domain that can be processed immediately. - insecure ?bool [
False]: Whether to ignore SSL certification errors when performing requests.
Yields:
A FetchWorkerResult having the following attributes:
- url ?string: the fetched url.
- item any: original item from the iterator.
- error ?Exception: an error.
- response ?urllib3.HTTPResponse: the http response.
- meta ?dict: additional metadata:
- mime ?string: resource's mimetype.
- ext ?string: resource's extension.
- encoding ?string: resource's encoding.
multithreaded_resolve
Function resolving url redirections in a multithreaded fashion.
from minet import multithreaded_resolve
# Most basic usage
urls = ['https://bit.ly/whatever', 'https://t.co/whatever']
for result in multithreaded_resolve(urls):
print(result.stack)
# Using a list of dicts
urls = [
{
'url': 'https://bit.ly/whatever',
'label': 'Bit.ly'
},
{
'url': 'https://t.co/whatever',
'label': 'Twitter'
}
]
for result in multithreaded_resolve(urls, key=lambda x: x['url']):
print(result.stack)
Arguments:
- iterator iterable: An iterator over urls or arbitrary items, if you provide a
keyargument along with it. - key ?callable: A function extracting the url to fetch from the items yielded by the provided iterator.

resolvehelper for a call. - threads ?int [
25]: Number of threads to use. - throttle ?float|callable [
0.2]: Per-domain throttle in seconds. Or a function taking the domain and current item and returning the throttle to apply. - max_redirects ?int [
5]: Max number of redirections to follow. - follow_refresh_header ?bool [
False]: Whether to followRefreshheaders or not. - follow_meta_refresh ?bool [
False]: Whether to follow meta refresh tags. It's more costly because we need to stream the start of the response's body and cannot rely on headers alone. - buffer_size ?int [
25]: Max number of items per domain to enqueue into memory in hope of finding a new domain that can be processed immediately. - insecure ?bool [
False]: Whether to ignore SSL certification errors when performing requests.
Yields:
