Fix max stack error.

See http://stackoverflow.com/questions/23702801/grunt-task-error-maximum-call-stack-size-exceeded-when-using-grunt-markdown and caolan/async#75

[craigshoemaker]

nice, @vladikoff! You could even bring it down to:

 process.nextTick(next);

This is a huge help! I hope @treasonx has some time to review and check in sometime soon :)

[treasonx]

So silly that I didn't think of this, who would need more than like 5 Markdown files ;P

I need to update a couple of the license documents, i'll merge test and push an update to NPM tomorrow.

Thanks a lot!

[vladikoff]

@craigshoemaker ah yes, PR Updated. was in a rush to help you :)

[craigshoemaker]

thanks to you both! 😄

[treasonx]

Pushed 0.6 to NPM with this PR and a bunch of changes for testing and code coverage.

Thanks!

[alanhogan]

This seems to be happening for me still; I am using 0.6.1

[treasonx]

@alanhogan can i have some more details? Number of files, config, and a stack trace would be awesome.

@treasonx

I have only one MD file and I have very little grunt experience, so apologies if I made a dunderheaded mistake.

Config:

module.exports = function(grunt) {

  // Project configuration.
  grunt.initConfig({
    pkg: grunt.file.readJSON('package.json'),

    uglify: {
      build: {
        src: 'js/global.js',
        dest: 'js/build/global.min.js'
      }
    },

    compass: {
      dist: {}
    },


    watch: {
      scripts: {
        files: ['js/*.js'],
        tasks: ['uglify'],
        options: {
          spawn: false,
        },
      },

      css: {
        files: ['sass/*.scss','sass/core/*.scss', 'sass/modules/*.scss', 'sass/layouts/*scss'],
        tasks: ['compass'],
        options: {
          spawn: false,
        },
      },


      markdown: {
        files: [
          {
            expand: true,
            src: 'docs/*.md',
            dest: 'docs/build/',
            // dest: 'build/',
            ext: '.html'
          }
        ],
        options: {
          // template: 'myTemplate.jst',
          // preCompile: function(src, context) {},
          // postCompile: function(src, context) {},
          // templateContext: {},
          markdownOptions: {
            gfm: true,
            spawn: false,
            // highlight: 'manual',
            // codeLines: {
            //   before: '<span>',
            //   after: '</span>'
            // }
          }
        }

      },

    },

    connect: {
      server: {
        options: {
          port: 3000,
          hostname: '*',
          onCreateServer: function(server, connect, options) {
            var io = require('socket.io').listen(server);
            io.sockets.on('connection', function(socket) {
              // do something with socket
            });
          }
        }
      }
    }

[alanhogan]

I was able to avoid the problem by moving markdown out of watch and into its own task. Is there a way to use grunt-markdown with watch?

[treasonx]

Hmm that stack trace is interesting.

It looks like its coming from util.js not sure what that is.. Is this the entire stack trace you get?

I used this grunt task exclusively in a watch when I first wrote it :) I didnt run into any problems.

I dont see grunt-markdown as part of your watch in the config you posted.

[shama]

@alanhogan It looks like the config for the markdown task is within the config for the watch task. The watch task is trying to read the markdown: { files: [{ /* ... */ }], } and getting confused. Move that outside of the watch config block.

[vladikoff]

@alanhogan , Probably need something like that as @shama is saying:

module.exports = function(grunt) {

  // Project configuration.
  grunt.initConfig({
    pkg: grunt.file.readJSON('package.json'),

    uglify: {
      build: {
        src: 'js/global.js',
        dest: 'js/build/global.min.js'
      }
    },

    compass: {
      dist: {}
    },


    watch: {
      scripts: {
        files: ['js/*.js'],
        tasks: ['uglify'],
        options: {
          spawn: false,
        },
      },

      css: {
        files: ['sass/*.scss','sass/core/*.scss', 'sass/modules/*.scss', 'sass/layouts/*scss'],
        tasks: ['compass'],
        options: {
          spawn: false,
        },
      },

    },

    markdown: {
      files: [
        {
          expand: true,
          src: 'docs/*.md',
          dest: 'docs/build/',
          // dest: 'build/',
          ext: '.html'
        }
      ],
      options: {
        // template: 'myTemplate.jst',
        // preCompile: function(src, context) {},
        // postCompile: function(src, context) {},
        // templateContext: {},
        markdownOptions: {
          gfm: true,
          spawn: false,
          // highlight: 'manual',
          // codeLines: {
          //   before: '<span>',
          //   after: '</span>'
          // }
        }
      }

    },


    connect: {
      server: {
        options: {
          port: 3000,
          hostname: '*',
          onCreateServer: function(server, connect, options) {
            var io = require('socket.io').listen(server);
            io.sockets.on('connection', function(socket) {
              // do something with socket
            });
          }
        }
      }
    }


  });

  // Load the plugin that provides the "uglify" task.
  grunt.loadNpmTasks('grunt-contrib-uglify');
  //grunt.loadNpmTasks('grunt-contrib-sass');
  grunt.loadNpmTasks('grunt-contrib-watch');
  grunt.loadNpmTasks('grunt-contrib-connect');
  grunt.loadNpmTasks('grunt-contrib-compass');

  // grunt-markdown for github-flavored markdown:
  grunt.loadNpmTasks('grunt-markdown');

  // Default task(s).
  grunt.registerTask('default', ['connect', 'uglify', 'compass', 'watch']);

};

Also watch out you forgot a . in the last 'sass/layouts/*scss'], :)

[alanhogan]

Thanks, guys.
