I have code as follows to perform some validations on C++ and Javascript files:
However, when I want to add other extensions as well, say "py" or "sql", then the repeated OR starts to look contrived. I know I can use the -o operator to abbreviate the code a little bit, but isn't there a more terse way to perform checks like these? Perhaps a standard membership-of-array function?

gst-launch-ext
GStreamer(1)GStreamer(1)NAME
gst-launch-ext - Run a predefined GStreamer pipeline
SYNOPSIS
gst-launch-ext filename [filename...]
DESCRIPTION
gst-launch-ext is a tool that is used to run a basic predefined GStreamer pipeline. This application is only used as a quick test to
ensure proper working of codecs and GStreamer. It doesn't handle more advanced features like synchronisation.
All supported formats in GStreamer should be playable by simply typing:
gst-launch-ext filename
It will also print out the pipeline it uses, so you can customize it using cut and paste.
CONFIGURATION
gst-launch-ext can be configured by creating a .gst file in your home directory. This is a perl-style configuration file and can override
the defaults for audio and video output sinks.
Here is an example .gst file that implements the same defaults as hard-coded in the script :
$cfg{AUDIOSINK} = "osssink"; $cfg{VIDEOSINK} = "colorspace ! xvideosink";
You can change osssink to any of esdsink, alsasink, jacksink (if you have the plug-in), and you can change xvideosink to aasink or
sdlvideosink.
Other plug-ins might be used as well if GStreamer has them.
