regex - Is there any Python implementation of logstash's grok functionality? -


logstash's grok string parsing tool built on top of regex, provides many patterns make string parsing jobs easier, fell in love first time used it. unfortunately, it's written in ruby, makes impossible used in python projects, i'm wondering there python implementation of grok, or there python alternative can simplify string parsing grok do?

i'm not aware on python ports of grok, functionality seems pretty straightforward implement:

import re  types = {     'word': r'\w+',     'number': r'\d+',     # todo: extend me }   def compile(pat):     return re.sub(r'%{(\w+):(\w+)}',          lambda m: "(?p<" + m.group(2) + ">" + types[m.group(1)] + ")", pat)   rr = compile("%{word:method} %{number:bytes} %{number:duration}")  print re.search(rr, "hello 123 456").groupdict() # {'duration': '456', 'bytes': '123', 'method': 'hello'}

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;...
