## Installation
```
pip install rss-readerAPI
```
or make a clone of the repository:
```
>>> git clone https://github.com/Aleksey-Mikh/CLI_util_RSS_reader.git
```
After that, you need to go to the CLI_util directory:
```
>>> cd your_path/CLI_util_RSS_reader/
```
and install the utility:
```
>>> pip install -e .
```
Don't forget the dot at the end!
Now you can use the utility in two ways:
```
>>> python rss_reader.py https://people.onliner.by/feed --limit 1
```
or
```
>>> rss_reader https://people.onliner.by/feed --limit 1
```
If needed, add the path to the repo to the environment variable $PYTHONPATH. 
The script will be available from everywhere.

Linux:
```
>>> export PYTHONPATH="${PYTHONPATH}:<path to repo>"
```
Windows:
```
>>> set PYTHONPATH=%PYTHONPATH%;<path to repo>
```

---
## Usage
You can see the information about the utility using the following command:

      >>> rss_reader --help

      usage: rss_reader [-h] [--version] [--json] [--verbose] [--limit LIMIT] [--date DATE] [--to-html TO_HTML]
                        [--to-pdf TO_PDF] [--colorize]
                        [source]
      
      Pure Python command-line RSS reader.
      
      positional arguments:
        source             RSS URL
      
      optional arguments:
        -h, --help         show this help message and exit
        --version          Print version info
        --json             Print result as JSON in stdout
        --verbose          Outputs verbose status messages
        --limit LIMIT      Limit news topics if this parameter provided
        --date DATE        Take a date in %Y%m%d format. Example: 20191206
        --to-html TO_HTML  This argument receives the path where new HTML file will be saved.
        --to-pdf TO_PDF    This argument receives the path where new PDF file will be saved.
        --colorize         That will print the result of the utility in colorized mode.

You can see the version of the utility:
```
>>> rss_reader --version

Version 5.0.0
```
Argument `--version` will output the version despite other arguments:
```
>>> rss_reader https://people.onliner.by/feed --limit 1 --version

Version 5.0.0
```
When entering the `source` argument, the got page is parsed on the Internet,
if you specify the `--date some_date` argument, then the news is searched in the local storage
and an Internet connection is not required.

When you enter only `--date some_date`, the news will be searched for by the specified date. 
If the news is not found, an error will be returned:
```
>>> rss_reader --date 20210810

------------------------------------------ Start Program ------------------------------------------
[ERROR] No news was found for this date - 2021-08-10

------------------------------------------- Stop Program ------------------------------------------
```
If you enter `source` and `--date some_date` utility will search news by the got to date
and the got to site. If the news is not found, an error will be returned:
```
>>> rss_reader https://people.onliner.by/feed --date 20210810

-------------------------------------------------- Start Program -------------------------------------------------
[ERROR] No news was founded for this date: 20210810, and this source: https://people.onliner.by/feed

-------------------------------------------------- Stop Program --------------------------------------------------
```

If you want more information about how the program works you can enter the argument `--verbose`:

      >>> rss_reader https://people.onliner.by/feed --limit 4 --verbose
