@sequencemedia/watch-match

Watch a file system directory path and replace a string pattern in its files whenever a file is added or modified

From the command line

npm start -- \
  --path '~/Documents/m3u' \
  --from '/Users/sequencemedia/Music/m4a' \
  --to '/Volumes/Audio/Assets'

Or with the default export

import watchMatch from '@sequencemedia/watch-match/watch-match'

const path = '~/Documents/m3u'
const from = '/Users/sequencemedia/Music/m4a'
const to = '/Volumes/Audio/Assets'

watchMatch(path, from, to)

For example, You have an application generating m3u files. Each file is written to a directory

That directory is the path

cd ~/Documents/m3u
ls -l
-rw-r--r--    1 sequencemedia  staff    1879 04 Feb 08:08 The Doors - The Doors.m3u
-rw-r--r--    1 sequencemedia  staff    1879 04 Feb 08:09 The Doors - Strange Days.m3u
-rw-r--r--    1 sequencemedia  staff    1879 04 Feb 08:10 The Doors - Waiting For The Sun.m3u

Each file contains a pattern you want to replace. In this case, the pattern is also a file system path /Users/sequencemedia/Music/m4a (but it could be any string)

That is the from

#EXTM3U
#EXTINF:149,Break On Through (To The Other Side) - The Doors
/Users/sequencemedia/Music/m4a/The Doors/The Doors/01 Break On Through (To The Other Side).m4a
