Usage

Usage: lessby [options]

Options:
  -i, --input <folder>   input less folder
  -o, --output <folder>  output less folder
  -e, --extension <ext>  output file extension, eg. ' -e wxss '
  -b, --initial-build    compile less files before watch
  -r, --recursive        compile less files recursively
  -m, --minify           minify output file
  -s, --source-map       generate source map files
  --source-map-inline    generate inline source map files
  --one-time             compile less files ony once

  -h, --help             display help for command

-i, --input

required

Normally, lessby will watch all the .less files inside the input folder, this action is non-recursive.

lessby -i <folder_name>

-o, --output

lessby will output the .css files into the folder that you specified.

lessby -i <folder_name> -o <output_foler_name>

-e, --extension

Seriously, it's not just CSS out there.

This will compile all the less files into CSS files with .wxss extension. You can use whatever extension you want.

lessby -i <folder_name> -e wxss

-b, --initial-build

compile all the .less files once before watch

lessby -i <folder_name> -b

-r, --recursive

FINALLY!!!

A less compiler with recursive option!

lessby -i src -r

If src/ has a sub-folder, and it contains .less files, lessby will find it, and compile it.

-m, --minify

As mentioned above, this parameter minifies output files.

lessby -i src -r -m

-s, --source-map

lessby will generate source map files, those little things are helpful when in development.

lessby -i src -s

--source-map-inline

lessby will generate inline source map, this will overwrite the -s option

lessby -i src -s

--one-time

lessby will compile all the .less files only once, could be used in building stage.

lessby -i src --one-time

--mid-name

Script below will compile all the .less files from xxx.less to xxx.min.css.

lessby -i <folder_name> -m --mid-name min

Since file extension names are customizable, I think I'll make the middle name part customizable too, you can compile non-minified files with the name min in the middle, even if it is not recommended, but hey! Here we are!

--less-options

And finally, the original lessc options.

Since this is a npm pack based on lessc, So I think it'll be good in case you need something I didn't cover.
