Basic usage:: |

12
|
|
|
|
|
13
|
|
|
inv -l # list all available tasks |
|
14
|
|

inv build -f # build everything, forcefully |
|

inv build --docs # only build the docs |

dk-tasklib is a library of basic tasks that tries to automate common tasks. |
|
18
|
|
|
dk-tasklib will attempt to install any tools/libraries/etc. that are required, |
|
19
|
|
|
e.g. when running the task to compile x.less to x.css, it will check that |
|
20
|
|
|
the lessc compiler is installed (and if not it will attempt to install it). |
|
21
|
|
|
|
|

|
|
|
This file is an initial skeleton, you are supposed to edit and add to it so it |
|
23
|
|
|
will fit your use case. |
