cause of slowdowns. +// The solution is to chunkify the input into smaller strings. +// The chunks are stored in the `chunks` var, +// `j` holds the current chunk index, and `current` holds +// the index of the current chunk in relation to `input`. +// This gives us an almost 4x speed-up. +// +// - In many cases, we don't need to match individual tokens; +// for example, if a value doesn't hold any variables, operations +// or dynamic references, the parser can effectively 'skip' it, +// treating it as a literal. +// An example would be '1px solid #000' - which evaluates to itself, +// we don't need to know what the individual components are. +// The drawback, of course is that you don't get the benefits of +// syntax-checking on the CSS.

Matching and slicing on a huge input is often cause of slowdowns. +// The solution is to chunkify the input into smaller strings. +// The chunks are stored in the `chunks` var, +// `j` holds the current chunk index, and `current` holds +// the index of the current chunk in relation to `input`. +// This gives us an almost 4x speed-up. +// +// - In many cases, we don't need to match individual tokens; +// for example, if a value doesn't hold any variables, operations +// or dynamic references, the parser can effectively 'skip' it, +// treating it as a literal. +// An example would be '1px solid #000' - which evaluates to itself, +// we don't need to know what the individual components are. +// The drawback, of course is that you don't get the benefits of +// syntax-checking on the CSS.

Matching and slicing on a huge input is often cause of slowdowns. +// The solution is to chunkify the input into smaller strings. +// The chunks are stored in the `chunks` var, +// `j` holds the current chunk index, and `current` holds +// the index of the current chunk in relation to `input`. +// This gives us an almost 4x speed-up. +// +// - In many cases, we don't need to match individual tokens; +// for example, if a value doesn't hold any variables, operations +// or dynamic references, the parser can effectively 'skip' it, +// treating it as a literal. +// An example would be '1px solid #000' - which evaluates to itself, +// we don't need to know what the individual components are. +// The drawback, of course is that you don't get the benefits of +// syntax-checking on the CSS. This gives us a 50% speed-up in the parser, +// and a smaller speed-up in the code-gen. +// +// +// Token matching is done with the `$` function, which either takes +// a terminal string or regexp, or a non-terminal function to call. +// It also takes care of moving all the indices forwards. +// +// +less.Parser = function Parser(env) { + var input, // LeSS input string + i, // current index in `input` + j, // current chunk + temp, // temporarily holds a chunk's state, for backtracking + memo, // temporarily holds `i`, when backtracking + furthest, // furthest index the parser has gone to + chunks, // chunkified input + current, // index of current chunk, in `input` + parser; + + var that = this; + + // This function is called after all files + // have been imported through `@import`. + var finish = function () {}; + + var imports = this.imports = { + paths: env && env.paths || [], // Search paths, when importing + queue: [], // Files which haven't been imported yet + files: {}, // Holds the imported parse trees + mime: env && env.mime, // MIME type of .less files + push: function (path, callback) { + var that = this; + this.queue.push(path); + + // + // Import a file asynchronously + // + less.Parser.importer(path, this.paths, function (root) { + that.queue.splice(that.queue.indexOf(path), 1); // Remove the path from the queue + that.files[path] = root; // Store the root + + callback(root); + + if (that.queue.length === 0) { finish() } // Call `finish` if we're done importing + }, env); + } + }; + + function save() { temp = chunks[j], memo = i, current = i } + function restore() { chunks[j] = temp, i = memo, current = i } + + function sync() { + if (i > current) { + chunks[j] = chunks[j].slice(i - current); + current = i; + } + } + // + // Parse from a token, regexp or string, and move forward if match + // + function $(tok) { + var match, args, length, c, index, endIndex, k, mem; + + // + // Non-terminal + // + if (tok instanceof Function) { + return tok.call(parser.parsers); + // + // Terminal + // + // Either match a single character in the input, + // or match a regexp in the current chunk (chunk[j]). + // + } else if (typeof(tok) === 'string') { + match = input.charAt(i) === tok ? tok : null; + length = 1; + sync (); + } else { + sync (); + + if (match = tok.exec(chunks[j])) { + length = match[0].length; + } else { + return null; + } + } + + // The match is confirmed, add the match length to `i`, + // and consume any extra white-space characters (' ' || '\n') + // which come after that.

in the browser, several +// optimization had to be made: +// +// - Matching and slicing on a huge input is often cause of slowdowns. +// The solution is to chunkify the input into smaller strings. +// The chunks are stored in the `chunks` var, +// `j` holds the current chunk index, and `current` holds +// the index of the current chunk in relation to `input`. +// This gives us an almost 4x speed-up. +// +// - In many cases, we don't need to match individual tokens; +// for example, if a value doesn't hold any variables, operations +// or dynamic references, the parser can effectively 'skip' it, +// treating it as a literal. +// An example would be '1px solid #000' - which evaluates to itself, +// we don't need to know what the individual components are. +// The drawback, of course is that you don't get the benefits of +// syntax-checking on the CSS.

+// for example, if a value doesn't hold any variables, operations +// or dynamic references, the parser can effectively 'skip' it, +// treating it as a literal. +// An example would be '1px solid #000' - which evaluates to itself, +// we don't need to know what the individual components are. +// The drawback, of course is that you don't get the benefits of +// syntax-checking on the CSS.

into smaller strings. +// The chunks are stored in the `chunks` var, +// `j` holds the current chunk index, and `current` holds +// the index of the current chunk in relation to `input`. +// This gives us an almost 4x speed-up. +// +// - In many cases, we don't need to match individual tokens; +// for example, if a value doesn't hold any variables, operations +// or dynamic references, the parser can effectively 'skip' it, +// treating it as a literal. +// An example would be '1px solid #000' - which evaluates to itself, +// we don't need to know what the individual components are. +//

+// for example, if a value doesn't hold any variables, operations +// or dynamic references, the parser can effectively 'skip' it, +// treating it as a literal. +// An example would be '1px solid #000' - which evaluates to itself, +// we don't need to know what the individual components are. +// The drawback, of course is that you don't get the benefits of +// syntax-checking on the CSS.

Please first read the [issue guidelines](https://github.com/twbs/bootstrap/blob/master/CONTRIBUTING.md#using-the-issue-tracker) and search for existing and closed issues. If your problem or idea is not addressed yet, [please open a new issue](https://github.com/twbs/bootstrap/issues/new). + + +## Documentation + +Bootstrap's documentation, included in this repo in the root directory, is built with [Jekyll](http://jekyllrb.com) and publicly hosted on GitHub Pages at . The docs may also be run locally. + +### Running documentation locally + +1. If necessary, [install Jekyll](http://jekyllrb.com/docs/installation) (requires v1.x). + - **Windows users:** Read [this unofficial guide](https://github.com/juthilo/run-jekyll-on-windows/) to get Jekyll up and running without problems. We use Pygments for syntax highlighting, so make sure to read the sections on installing Python and Pygments. +2. From the root `/bootstrap` directory, run `jekyll serve` in the command line. + - **Windows users:** While we use Jekyll's `encoding` setting, you might still need to change the command prompt's character encoding ([code page](http://en.wikipedia.org/wiki/Windows_code_page)) to UTF-8 so Jekyll runs without errors. For Ruby 2.0.0, run `chcp 65001` first. For Ruby 1.9.3, you can alternatively do `SET LANG=en_EN.UTF-8`. +3. Open in your browser, and voilà. + +Learn more about using Jekyll by reading its [documentation](http://jekyllrb.com/docs/home/). + +### Documentation for previous releases + +Documentation for v2.3.2 has been made available for the time being at while folks transition to Bootstrap 3. + +[Previous releases](https://github.com/twbs/bootstrap/releases) and their documentation are also available for download. + + + +## Compiling CSS and JavaScript + +Bootstrap uses [Grunt](http://gruntjs.com/) with convenient methods for working with the framework. It's how we compile our code, run tests, and more. To use it, install the required dependencies as directed and then run some Grunt commands. + +### Install Grunt + +From the command line: + +1. Install `grunt-cli` globally with `npm install -g grunt-cli`. +2. Navigate to the root `/bootstrap` directory, then run `npm install`. npm will look at [package.json](https://github.com/twbs/bootstrap/blob/master/package.json) and automatically install the necessary local dependencies listed there. + +When completed, you'll be able to run the various Grunt commands provided from the command line. + +**Unfamiliar with `npm`? Don't have node installed?** That's a-okay. npm stands for [node packaged modules](http://npmjs.org/) and is a way to manage development dependencies through node.js. [Download and install node.js](http://nodejs.org/download/) before proceeding. + +### Available Grunt commands + +#### Build - `grunt` +Run `grunt` to run tests locally and compile the CSS and JavaScript into `/dist`. **Uses [Less](http://lesscss.org/) and [UglifyJS](http://lisperator.net/uglifyjs/).** + +#### Only compile CSS and JavaScript - `grunt dist` +`grunt dist` creates the `/dist` directory with compiled files. **Uses [Less](http://lesscss.org/) and [UglifyJS](http://lisperator.net/uglifyjs/).** + +#### Tests - `grunt test` +Runs [JSHint](http://jshint.com) and [QUnit](http://qunitjs.com/) tests headlessly in [PhantomJS](http://phantomjs.org/) (used for CI). + +#### Watch - `grunt watch` +This is a convenience method for watching just Less files and automatically building them whenever you save. + +### Troubleshooting dependencies + +Should you encounter problems with installing dependencies or running Grunt commands, uninstall all previous dependency versions (global and local). Then, rerun `npm install`. + + + +## Contributing + +Please read through our [contributing guidelines](https://github.com/twbs/bootstrap/blob/master/CONTRIBUTING.md).

+## What does `s3_cache.py` do?
+
+### In general
+`s3_cache.py` maintains a cache, stored in an Amazon S3 (Simple Storage Service) bucket, of a given directory whose contents are considered non-critical and are completely & solely determined by (and should be able to be regenerated from) a single given file.
+
+The SHA-256 hash of the single file is used as the key for the cache. The directory is stored as a gzipped tarball.
+
+All the tarballs are stored in S3's Reduced Redundancy Storage (RRS) storage class, since this is cheaper and the data is non-critical.
+
+`s3_cache.py` itself never deletes cache entries; deletion should either be done manually or using automatic S3 lifecycle rules on the bucket.
+
+Similar to git, `s3_cache.py` makes the assumption that [SHA-256 will effectively never have a collision](http://stackoverflow.com/questions/4014090/is-it-safe-to-ignore-the-possibility-of-sha-collisions-in-practice).
+
+
+### For Bootstrap specifically
+`s3_cache.py` is used to cache the npm packages that our Grunt tasks depend on and the RubyGems that Jekyll depends on. (Jekyll is needed to compile our docs to HTML so that we can run them thru an HTML5 validator.)
+
+For npm, the `node_modules` directory is cached based on our `npm-shrinkwrap.canonical.json` file.
+
+For RubyGems, the `gemdir` of the current RVM-selected Ruby is cached based on the `pseudo_Gemfile.lock` file generated by our Travis build script.
+`pseudo_Gemfile.lock` contains the versions of Ruby and Jekyll that we're using (read our `.travis.yml` for details).
+
+
+## Why is `s3_cache.py` necessary?
+`s3_cache.py` is used to speed up Bootstrap's Travis builds. Installing npm packages and RubyGems used to take up a significant fraction of our total build times. Also, at the time that `s3_cache.py` was written, npm was occasionally unreliable.
+
+Travis does offer built-in caching on their paid plans, but this do-it-ourselves S3 solution is significantly cheaper since we only need caching and not Travis' other paid features.
+
+
+## Setup
+
+### Overview
+1. Create an Amazon Web Services (AWS) account.
+2. Create an Identity & Access Management (IAM) user, and note their credentials.
+3. Create an S3 bucket.
+4. Set permissions on the bucket to grant the user read+write access.
+5. Set the user credentials as secure Travis environment variables.
+
+### In detail
+1. Create an AWS account.
+2. Login to the [AWS Management Console](https://console.aws.amazon.com).
+3. Go to the IAM Management Console.
+4. Create a new user (named e.g. `travis-ci`) and generate an access key for them. Note both the Access Key ID and the Secret Access Key.
+5. Note the user's ARN (Amazon Resource Name), which can be found in the "Summary" tab of the user browser. This will be of the form: `arn:aws:iam::XXXXXXXXXXXXXX:user/the-username-goes-here`
+6. Note the user's access key, which can be found in the "Security Credentials" tab of the user browser.
+7. Go to the S3 Management Console.
+8. Create a new bucket. For a non-publicly-accessible bucket (like Bootstrap uses), it's recommended that the bucket name be random to increase security. On most *nix machines, you can easily generate a random UUID to use as the bucket name using Python:
+
+    ```bash
+    python -c "import uuid; print(uuid.uuid4())"
+    ```
+
+9. Determine and note what your bucket's ARN is. The ARN for an S3 bucket is of the form: `arn:aws:s3:::the-bucket-name-goes-here`
+10. In the bucket's Properties pane, in the "Permissions" section, click the "Edit bucket policy" button.
+11. Input and submit an IAM Policy that grants the user at least read+write rights to the bucket. AWS has a policy generator and some examples to help with crafting the policy. Here's the policy that Bootstrap uses, with the sensitive bits censored:
+
+    ```json
+    {
+        "Version": "2012-10-17",
+        "Id": "PolicyTravisReadWriteNoAdmin",
+        "Statement": [
+            {
+                "Sid": "StmtXXXXXXXXXXXXXX",
+                "Effect": "Allow",
+                "Principal": {
+                    "AWS": "arn:aws:iam::XXXXXXXXXXXXXX:user/travis-ci"
+                },
+                "Action": [
+                    "s3:AbortMultipartUpload",
+                    "s3:GetObjectVersion",
+                    "s3:ListBucket",
+                    "s3:DeleteObject",
+                    "s3:DeleteObjectVersion",
+                    "s3:GetObject",
+                    "s3:PutObject"
+                ],
+                "Resource": [
+                    "arn:aws:s3:::XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX",
+                    "arn:aws:s3:::XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX/*"
+                ]
+            }
+        ]
+    }
+    ```
+
+12. If you want deletion from the cache to be done automatically based on age (like Bootstrap does): In the bucket's Properties pane, in the "Lifecycle" section, add a rule to expire/delete files based on creation date.
+13. Install the [`travis` RubyGem](https://github.com/travis-ci/travis): `gem install travis`
+14. Encrypt the environment variables:
+
+    ```bash
+    travis encrypt --repo twbs/bootstrap "AWS_ACCESS_KEY_ID=XXX"
+    travis encrypt --repo twbs/bootstrap "AWS_SECRET_ACCESS_KEY=XXX"
+    travis encrypt --repo twbs/bootstrap "TWBS_S3_BUCKET=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX"
+    ```
+
+14. Add the resulting secure environment variables to `.travis.yml`.
+
+
+## Usage
+Read `s3_cache.py`'s source code and Bootstrap's `.travis.yml` for how to invoke and make use of `s3_cache.py`.
