This is a Grunt plugin that searches a list of files for particular search strings and logs the results in JSON, XML, text or JUnit format - or just output to the console. It also provides an option to fail the build process, should you need it.
There are a bunch of search-and-replace Grunt plugins out there, but we needed something simpler for logging purposes only. We wanted to run various tests on our codebase to look for certain things: inline styles, inline event handlers, old, unwanted HTML tags. None of these weren't significant enough to warrant failing the build, but they do give a clue as the health of the codebase.
So basically, we run this function along with jshint
in our dev environments to warn us about the accumulation of crap.
This plugin requires Grunt v0.4.1+.
In your project folder, run the following command:
npm install grunt-search --save-dev
Once the plugin has been installed, you need to add this line of JS to your gruntfile:
grunt.loadNpmTasks('grunt-search');
That will reference this module and allow you to use it.
If you're familiar with Grunt, it's pretty straightforward to use. Here's a few example searches so you can get the idea of how it operates.
grunt.initConfig({
search: {
// Example 1: search for inline style tags
inlineStyles: {
files: {
src: ["*.html", "**/*.hbs"]
},
options: {
searchString: /style\s?=\s?["']*/g,
logFile: "tmp/results.json"
}
},
// Example 2: look for any developers leaving obscenities in the codebase
obscenities: {
files: {
src: ["*"]
},
options: {
searchString: /(poop|fart|Barbara\sStreisand)/g,
logFile: "tmp/results.xml",
logFormat: "xml",
failOnMatch: true,
onMatch: function(match) {
// called when a match is made. The parameter is an object of the
// following structure: { file: "", line: X, match: "" }
},
onComplete: function(matches) {
// called when all files have been parsed for the target. The
// matches parameter is an object of the format:
// `{ numMatches: N, matches: {} }`. The matches /property is
// an object of filename => array of matches
},
}
},
// Example 3: search a PHP codebase for short-tags and just output the findings to
// the console (short tags can be disabled, so this helps prevent them sneaking in!)
short_tags: {
files: {
src: ["**/*.php"]
},
options: {
searchString: /(<\?[^p])|(<\?$)/,
logFormat: "console"
}
},
// Example 4: custom logging function. This example shows how you can access the raw results to
// do whatever you want with it.
chicken_sounds: {
files: {
src: ["*"],
},
options: {
searchString: /cluck|cluckity|bwaaaaaah!|/,
logFormat: "custom",
customLogFormatCallback: function(params) {
/*
// here, params is an object containing the following
{
filePaths: [], // an array of file paths
results: [], // the results
numResults: X // the number of results
}
*/
}
}
}
}
});
The files
property should be an object with a single src
property containing an array of files, or file patterns.
This plugin uses Grunt's file globbing patterns, documented here:
http://gruntjs.com/configuring-tasks
The options
property can contain any of the following:
json
) the format of the log file: json
, xml
, junit
, text
, custom
,
or console
. The json, XML, text and console options are self explanatory; the junit option logs the information in
an XML format understood by JUnit; and the custom option lets you pass off the logging to your own function, defined
(or at least accessible) to your gruntfile. For that, you need tocustom
for the logFormat setting). If you want, you can define
your own logging function to access the raw info. Take a look at the chicken_sounds example above to see how to configure
this, and the data structure you get passed to your callback function.console
) the location of the file to be created. Like all things with
Grunt, this is relative to the Grunt root.false
). This option lets you choose to fail the build process if any matches
are found.false
). Sometimes it's not totally clear what files are
being matched by the file globbing. When this option is set to true
, the generated output file contains a list of the
files that had been examined.false
. Determines if the match should be scoped to the line or file.
For example, when set to true
, all matches would be handled for files and parameters for onMatch
and logCondition would be passed as { file: "", line: [X, X], match: ["", ""] }
per one for each file where one
or multiple matches occurred.{ numMatches: N, matches: {} }
. The matches property is an object of
filename => array of matches. Note: this function doesn't get called in the event of a fatal error (i.e. a required
options parameter wasn't properly included).{ file: "", line: X, match: "" }
{ file: "", line: X, match: "" }
. If this function
returns true
the match would be included, if false
it is not.true
this function would be evaluated to determine if should this item be marked in JUnit report or not. It's passed two parameters, file dir object
with the following structure: { line: X, match: "" }
( or { line: [X,..], match: ["",..] }
, if scopeMatchToFile set to true
). If this function returns true
JUnit will mark this match as failed, if false
JUnit will mark this match as passed.Note: if either of the required parameters are omitted, the build will fail.
junit
logFile option value added for generating JUnit XML reports. Courtesy of Sergii Iavorsky.console
logFile option value added for simply outputting results to console. Now the number of
matches is always output to the console regardless of logFile type, as well as being logged in the generated file.MIT, baby.
