Usage

Library

srtfiles = ['/data/TVSeries/Cosmos/Cosmos.S01E01.srt',
            '/data/TVSeries/Cosmos/Cosmos.S01E02.srt']

srtcleaner.srtcleaner([srtfiles], in_place=True, backup=False, convert='UTF-8')

Command-line

$ srtcleaner --help

usage: srtcleaner [-h] [-q | -v] [--recursive] [--input-encoding ENCODING]
                  [--input-fallback-encoding FALLBACK_ENCODING]
                  [--convert OUTPUT_ENCODING] [--in-place] [--no-backup]
                  [--no-rebuild-index] [--blacklist BLACKLISTPATH]
                  srtpaths [srtpaths ...]

Clean subtitles deleting items that matches entries in blacklist file. Useful
to remove ads and misplaced credits

positional arguments:
  srtpaths              SRT file(s) or dir(s) to modify

optional arguments:
  -h, --help            show this help message and exit
  -q, --quiet           Suppress informative messages and summary statistics.
  -v, --verbose         Print additional information for each processed file.
  --recursive, -r       recurse inside directories.
  --input-encoding ENCODING, -e ENCODING
                        Encoding used in subtitles, if known. By default tries
                        to autodetect encoding.
  --input-fallback-encoding FALLBACK_ENCODING, -f FALLBACK_ENCODING
                        Fallback encoding to read subtitles if encoding
                        autodetection fails. [Default: windows-1252]
  --convert OUTPUT_ENCODING, -c OUTPUT_ENCODING
                        Convert subtitle encoding. By default output uses the
                        same encoding as the input.
  --in-place, -i        Overwrite original file instead of outputting to
                        standard output
  --no-backup, -B       When using --in-place, do not create a backup file.
  --no-rebuild-index, -I
                        Do not rebuild subtitles indexes after removing items.
                        Resulting SRT will not be strictly valid, although it
                        will work in most players. Useful when debugging for
                        comparing original and modified subtitles
  --blacklist BLACKLISTPATH, -b BLACKLISTPATH
                        Blacklist file path. [Default:
                        /home/user/.config/srtcleaner/srtcleaner.conf]

Configuring

SRT Cleaner will remove any entries that matches any record on its blacklist file, located by default at ~/.config/srtcleaner/srtcleaner.conf. Create or edit it before using srtcleaner.

A record can span over multiple lines, so use a blank line to separate each record. Its text is matched against each SRT entry by a simple text in entry comparison, in a case-insensitive way. So if the whole text is found as part of an entry, the whole entry is removed from the SRT file. Escape sequences such as '\n' and '\t' are also interpreted, so you can use '\n' when you want to include a newline at the end of the text to match.

Example of a basic srtcleaner.conf:

Requirements

• Pysrt, to parse the SRT files
• file-magic, to detect encoding.

Note: There are (at least) 3 python modules named magic available on PyPI, all wrappers to libmagic, but with very distinct API:

• file-magic, from libmagic project itself
• python-magic
• filemagic

SRT Cleaner supports any of the above libmagic wrappers, and on install pulls the one from the file/libmagic project. And all of them obviously requires libmagic to be installed on your system. It usually ships in the file package and comes pre-installed in most GNU/Linux distributions and MacOS.

On Windows, the following could be used to install libmagic:

• file-windows
• libmagicwin64

Installing

From Git:

git clone https://github.com/MestreLion/strcleaner
cd strcleaner
pip install --user -e .

From PyPi:

pip install --user strcleaner
