Regular Expressions

Poems & patterns in your ears. A simple interface for converting written text into OSC messages.

Setup

Install npm dependencies:

npm install

Install bower dependencies:

bower install

Start the server:

grunt

Open up your browser to http://localhost:3000

OSC Endpoints

• /com/notioncollective/key - fires on every keydown in text input
• /com/notioncollective/[n] - all messages for expression #n
• /com/notioncollective/notes - each individual matched note is a separate param, with a number
• /com/notioncollective/[n]/notes - same as above, but only for the selected regex
• /com/notioncollective/words - word count for entire contents of text input
• /com/notioncollective/[n]/words - word count for matches of expression n
• /com/notioncollective/chars - chartacter count for entire contents of text input
• /com/notioncollective/[n]/chars - character count for matches for expression n
• /com/notioncollective/count - count of matches for all regexes
• /com/notioncollective/[n]/count - count of matches for regex #n

Some handy regular expressions

• /[^\s]*?abc[^\s]*?$/ - Capture words that contain "abc" only if they are the last word in the line
• /\w+\.$/ - Capture the last word in a sentence followed by a period.
• /(^|\n)+?\n$/ - Capture the last line
• /(\n|^).*?\n/ - Capture every line
• How to do not a word? Almost there but not quite

Todo

• Change OSC namespacing from notioncollective to regexpoetics
• Write instructions for setup
• Clean up samples/scores
• Figure out a way to have pd samples auto-load? (might not be possible)
• Figure out how to have mixer automatically set itself up? (might be a pain)
• Button to show/hide regular expressions
• send ascii characters instead of notes
• Add ability to do sharps/flats
  • captial letter is sharp?
• Add ability to add flags to regex
• Control panel buttons
  • There should be an "Update" button for updating the fields
    • This will just send both the host and port (on client)
  • "Reset" button
    • Send an OSC reset message (on server)
    • Clear all input fields (on client)
  • "Sync" button?
• Maybe we should use captures and not matches? Have to think about this a bit
• Abstract messaging a bit so that all osc messages are also sent back to the client
• Update namespacing to "/com/nc/regexpoetics/" ? Or something project-specific.
• BUG: Sometimes live updating interferes with your typing.
  • Possible fix: each client gets a client id, sends that id with messages.
