Simple file change monitoring for any kind of development.

Note: Noprob has just been released and I haven't had the chance to test it on Windows yet. I'll get to it soon.

Why? ---- Having a utility that can restart or recompile or reconfigure or re*whatever* whenever you change a file can be incredibly convenient. Many programs of this sort are geared to work with a specific toolchain or tend to be overly complicated for what should be a simple task.

No worries. Noprob's got your back, no problem.

Installation ---- [Install npm.]( (it comes with Node.js).

Run: $ npm -g install noprob

Options ---- * -h, --help * Output usage information. * -x, --exec [command] * String to execute globally on any file change. * Wrap command strings in single `'` or double `"` quotes (though they can be left off if you are doing a simple command with no spaces or special characters like `ls`). * Global commands run once on startup and then upon every file change that matches the specified extensions. * -l, --local [command] * String to execute locally on any file that's changed as it is changed. Wrap in quotes as needed. * Local commands have the unique ability to use [command tags](#d) to dynamically insert information sections of the changed file's path. * -w, --watch [directory] * Directory to watch. * -e, --extension [extensions] * List of file extensions to watch. Wrap in quotes as needed. * Separate extensions with a `|`. * -d, --dot * Watch hidden dot files. * Files that begin with a '.' or that are in a folder that begins with a '.' are ignored by default. Use this option to watch them. Local Command Tags ---- Tags can be an extremely powerful way to execute commands on specific files. Simply insert the tags into your local command string like `noprob -l 'echo '` and they will be replaced with the associated information from the changed file's path.
  • is the full path (e.g. path/to/file.txt)
  • is the directory that contains the file (e.g. `path/to/`)
  • is the full filename including the extension (e.g. file.txt)
  • is the file's name without the extension (e.g. file)
  • is the file's extension (e.g. txt)

To further demonstrate, the following commands are equivalent:

$ noprob -l 'echo <full>'

$ noprob -l 'echo <dir><fullfile>'

$ noprob -l 'echo <dir><name>.<ext>'

though the last command would be left with a trailing . if the file has no extension while the other two would not.

Example Usage ---- Run and restart a node server on javascript source changes: * `$ noprob -x 'node server.js' -e 'js'`

Compile individual coffescript files in the "src" folder into javascript on demand (closely mimics coffescript's internal --watch option):

  • $ noprob -l 'coffee -c <fullfile>' -e 'coffee' -w src

Copy changed txt files into a mirrored directory tree under the 'copies' folder but with a .changed before the extension:

  • $ noprob -l 'mkdir -p copies/<dir> ; cp <full> copies/<dir><name>.changed.<ext>' -e txt
