java - nested property-read in manifest -


i have following build.xml code. here modify manifest file in jar file. in manifest wanted add few attributes such asset-name , asset-baseline.

content of buildinfo.properties followed:

articlelib_componentname=abc component. articlelib_baselinename=baseline_1. buslib_componentname=xyz component. buslib_baselinename=baseline_2.

build.xml: want pass name i.e articlelib value dynamically, , retrieve values buildinfo.properties. used macrodef outside manifest it's working file when use same in manifest tag i'm unable use it. can have work around problem or alternative solution pass dynamic values manifest can retrieve values builinfo.properties

<property name="name" value="articlelib" />  <property name="name_path" value="${name}_componentname" /> <property file="buildinfo.properties" prefix="buildinfo" />  <property file="buildinfo.properties"/>      <macrodef name="property-read">         <attribute name="name"/>         <attribute name="from"/>         <sequential>             <property name="@{name}" value="${@{from}_componentname}"/>         </sequential>     </macrodef>      <target name="test">         <echo>product_name: ${name}</echo>         <property-read name="instance" from="${name}"/>         <echo>dynamic property value: ${instance}</echo>     </target>  <target name="earchive" description="generate ear file">          <jar destfile="${dir.dist}/${name}.jar">             <manifest>                 <attribute name="specification-title" value="${name}" />                 <property-read name="instance" from="${name}"/>                 <attribute name="asset-component" value="${instance}" />                 <echo>dynamic property value: ${instance}</echo>                 <attribute name="asset-baseline" value="${buildinfo.articleliblocal.baselinename}" />             </manifest>         </jar>      </target> </project>

when use above property-read micro in manifest tag following error:

build failed

assigned dynamic value new variable outside manisfest , read same variable in manifest solved issue.

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;...

python 3.x - Mapping specific letters onto a list of words -

can please suggest approach write piece of codes automatically maps letter in letter_str onto dic_key (a dict key string type contains dashes match length of words in word_lst)? so, mapping occurs if letter appears in every words in list @ same position no matter how many words in list. if no letter appears @ position words in word list new_dic_key '----'. please see examples below thanks word_lst = ['ague', 'bute', 'byre', 'came', 'case', 'doze'] dic_key = '----' letters_str ='abcdefghijklmnopqrstuvwxyz' new_dic_key = '---e' if word_list = ['bute', 'byre'] new_dic_key = 'b--e' or word_list = ['drek', 'drew', 'dyes'] new_dic_key = 'd-e-' if words in word_list of same length code give want: word_list = ['drek', 'drew', 'dyes'] cols = [] in range(len(word_list[0])): cols.append([]) word in ...
