gruntjs - Pass the name of watched file that changed as argument to a shell command -


i have collection of .svg files. when modify 1 of them, grunt re-run command on each svg file modified

inkscape --file=filename.svg --export-pdf=filename.pdf

so far, have grunt script

module.exports = function (grunt) { 'use strict'; grunt.initconfig({   shell: {     figures: {       command: 'inkscape --file=filename.svg --export-pdf=filename.pdf'     }   },   watch: {     figs: {       files: '**/*.svg',       tasks: ['shell:figures']     }   } }); grunt.loadnpmtasks('grunt-contrib-watch'); grunt.loadnpmtasks('grunt-shell');  grunt.registertask('default', [watch']); };

but have no idea how configure grunt in order replace filename name of each file modified.

i solved issue using config variable modified on watch event before shell:figs runs

module.exports = function (grunt) {   'use strict';   // project configuration   grunt.initconfig({     shell: {       figs: {         command: function() {           return 'inkscape --file="' + grunt.config('shell.figs.src') + '" --export-pdf="' + grunt.config('shell.figs.src').replace('.svg', '.pdf') + '"';         },         src: '**/*.svg'       }     },     watch: {       svgs: {         files: '**/*.svg',         tasks: ['shell:figs'],         options: {         spawn: false,         }       }     }   });    grunt.event.on('watch', function(action, filepath) {     grunt.config('shell.figs.src', filepath);   });    // these plugins provide necessary tasks   grunt.loadnpmtasks('grunt-contrib-watch');   grunt.loadnpmtasks('grunt-shell');    // default task   grunt.registertask('default', ['connect', 'watch']); };

the downside shell:figs cannot called manually, works when running watch task, or grunt.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
