node.js - Add a Timestamp to the End of Filenames with Grunt -


during grunt tasks, add unique string end of filenames. have tried grunt-contrib-copy , grunt-filerev. neither have been able need them to...

currently less files automatically compiled on 'save' in sublime text 3 (so not yet occur in grunt tasks). then, open terminal , run 'grunt', concatenates (combines) js files. after done, grunt should rename 'dist/css/main.css' , 'dist/js/main.js' "version" @ end of filename.

i have tried:

  • grunt-contrib-copy ('clean:expired' deletes concatenated js before grunt-contrib-copy' can rename file)
  • grunt-filerev ('this worked on css files reason, , inserted version number before '.css'. not sure why didn't work on js files.')

here's gruntfile.js

so, clear, not asking "code review" need know how can incorporate "rename" process when tasks complete, have 'dist/css/main.css12345 & dist/js/main.js12345' no 'dist/css/main.css' or 'dist/js/main.js' left in respective directories.

thanks in advance help!

update: after experimenting this, ended using grunt-contrib-rename , works great! beleieve same results can achieved via grunt-contrib-copy, in fact know same thing. either work. far support regex, not sure if both support it, may else worth looking before choosing 1 of these plugins :)

your rename:dist looks should want, need move clean:dist first task runs (so deletes things prior build rather current build). order of tasks defined array on last line:

grunt.registertask('default', ['jshint:dev', 'concat:dist', 'less:dist', 'csslint:dist', 'uglify:dist', 'cssmin:dist', 'clean:dist', 'rename:dist']);

that said, i'm not sure why want behavior. more common thing insert hash of file filename before file extension.

the difference between hash , timestamp hash value same long file contents don't change - if change 1 file, compiled output file different , browsers need re-downloaded 1 file while using cached versions of every other file.

the difference between putting number before file extension , after extension lot of tools (like ide) have behavior changes based on extension.

for more standard goal, there tons of ways accomplish 1 of more common combine grunt-filerev grunt-usemin create named files , update html file(s) reference these new file names

css - SVG using textPath a symbol not rendering in Firefox -

using textpath within symbol doesn't render in firefox. renders fine in latest chrome , ie, when try reference symbol, svg text doesn't render in firefox (37.0.1) - first box appears empty. code below (no external dependencies), there should 2 boxes word test flowing vertically in centre of each. edit: thought issue somehow involved flexbox layout, until paul pointed out issue exists without flexbox layout. the html is: <div> <svg id="not_working" viewbox="0 0 250 1200" preserveaspectratio="xmidymid meet"> <symbol id="test_symbol1" preserveaspectratio="xmidymid meet" viewbox="0 0 250 1200"> <path id="test_symbol_path" d="m 100 1200 l 100 0" /> <text font-size="100" fill="red"> <textpath text-anchor="middle" startoffset="50%" xlink:href="#test_symbol_path&q

node.js - How to abort query on demand using Neo4j drivers -

i making search engine application using node.js , neo4j allows users submit graph traversal query via web-based user interface. want give users option cancel query after has been submitted (i.e. if user decides change query parameters). thus, need way abort query using either command node.js-to-neo4j driver or via cypher query. after few hours of searching, haven't been able find way using of node.js-to-neo4j drivers. can't seem find cypher query allows killing of query. overlooking something, or not possible neo4j? using neo4j 2.0.4, willing upgrade newer version of neo4j if has query killing capabilities. starting neo4j version 2.2.0, it's possible kill queries ui , via rest interface. don't know if existing nodejs drivers support feature, if not can still achieve same functionality making http request rest interface. if run query in browser in version 2.2.x or later, notice there (x) close link @ top-right corner of area queries executed , displayed
