makefile - Why do the scripts and comments appear during execution? -


in makefile, have target called indent-fast --

indent-fast:     # astyle --style=allman --indent=tab `find . -name "*.java"`     files=`find . -name "*.java"` ; \     file in $$files ; \         echo formatting $$file ; \     done ;\     # whitesmith @ 4 spaces, uncomment line --     # astyle --style=whitesmith --indent=spaces=4 `find . -name "*.java"`

but when execute it, output --

ramgorur@ramgorur-pc:~$ make indent-fast  # astyle --style=allman --indent=tab `find . -name "*.java"` files=`find . -name "*.java"` ; \     file in $files ; \         echo formatting $file ; \     done ;\ formatting ./file1.java formatting ./file2.java formatting ./file3.java . . . formatting ./filen.java # whitesmith @ 4 spaces, uncomment line -- # astyle --style=whitesmith --indent=spaces=4 `find . -name "*.java"`

why showing scripts along comments on std output? please note indent-fast last target in file.

because comments indented in recipe, they're not make comments, , they're being executed part of recipe. they're shell comments in context. add @ prevent them being output, if that's goal.

from gnu make manual:

comments within recipe passed shell, other recipe text. shell decides how interpret it: whether or not comment shell.

simple example makefile:

# make comment target:     # shell comment     :     @# output-suppressed shell comment     @:

execution:

$ make # shell comment :

edit: since example wasn't enough, here's solution exact problem:

indent-fast:     @# astyle --style=allman --indent=tab `find . -name "*.java"`     @files=`find . -name "*.java"` ; \     file in $$files ; \         echo formatting $$file ; \     done     @# whitesmith @ 4 spaces, uncomment line --     @# astyle --style=whitesmith --indent=spaces=4 `find . -name "*.java"`

Why can rails not find a route created by a helper? -

i created member route in rails 4: resources :line_items post 'decrement', on: :member end and gave matching method in line_items controller: def decrement @cart = current_cart @line_item = @cart.line_items.find_by_id(params[:id]) @line_item.decrement_quantity respond_to |format| if @line_item.save format.html { redirect_to shop_path, notice: 'line item updated.' } format.js {@current_item = @line_item} format.json { head :ok } else format.html { render action: "edit" } format.js {@current_item = @line_item} format.json { render json: @line_item.errors, status: :unprocessable_entity } end end end but when try make button: <%= button_to 'x', decrement_line_item_path(item) %> i error: no route matches [post] "/carts/25" what gives? your error message is: no route matches [post] "/carts/25" but expectin...

opencv - DataType<cv::detail::deriv_type>::depth what is it used for -

i wondering why line used in lucas kanade tracker in opencv: datatype<cv::detail::deriv_type>::depth can explain me? in opencv, depth of mat refers type of data contained in mat 's data buffer. represented integer values correspond given data type. these integers commonly abstracted appropriate macro definition (e.g. uchar data represented macro cv_8u ). cv::datatype type-traits class provides method obtain corresponding integer value without having memorize macro means data type. there few cases user code needs use datatype::depth . more common datatype::type . a simple example shows 1 possible use of datatype::depth : cv::mat uchar_data = cv::mat::ones(3, 3, cv_8uc1); cv::mat float_data; uchar_data.convertto(float_data, cv::datatype<float>::depth); // ^^ equivalently replaced // cv_32f macro float_data.at<float>(0,1) += 0.5f; std::cout << float_data << std::endl;...
