PylpChanged

Information

pylpchanged is a plugin for Pylp that filter unchanged files.

Note: this plugin cannot filter unchanged files with a name transformed by another plugin further into the stream (pylprename for example).

Installation

Install pylpchanged with pip:

pip install pylpchanged

If you don't have Python Scripts folder in your PATH, you can run also:

python -m pip install pylpchanged

Usage

The usual use of pylpchanged is as follows:

import pylp
from pylpchanged import pylpchanged

pylp.task('default', lambda:
    pylp.src('lib/*.py')
      .pipe(changed())
    # .pipe(another_plugin())
      .pipe(pylp.dest('build'))
)

Without parameters, pylpchanged will wait for the destination stream (i.e. pylp.dest) to compare the last result with the source files.

For a faster execution, you can pass directly the destination path like this:

import pylp
from pylpchanged import pylpchanged

pylp.task('default', lambda:
    pylp.src('lib/*.py')
      .pipe(changed('build'))
    # .pipe(another_plugin())
      .pipe(pylp.dest('build'))
)
