+;; Minor mode to adaptively set fill-prefix and overload filling functions|
+;; 28-February-1998|2.12|~/packages/filladapt.el|
+
+;; These functions enhance the default behavior of Emacs' Auto Fill
+;; mode and the commands fill-paragraph, lisp-fill-paragraph,
+;; fill-region-as-paragraph and fill-region.
+;;
+;; The chief improvement is that the beginning of a line to be
+;; filled is examined and, based on information gathered, an
+;; appropriate value for fill-prefix is constructed. Also the
+;; boundaries of the current paragraph are located. This occurs
+;; only if the fill prefix is not already non-nil.
+;;
+;; The net result of this is that blurbs of text that are offset
+;; from left margin by asterisks, dashes, and/or spaces, numbered
+;; examples, included text from USENET news articles, etc. are
+;; generally filled correctly with no fuss.
+;;
+;; Since this package replaces existing Emacs functions, it cannot
+;; be autoloaded. Save this in a file named filladapt.el in a
+;; Lisp directory that Emacs knows about, byte-compile it and put
+;; (require 'filladapt)
+;; in your .emacs file.
+;;
+;; Note that in this release Filladapt mode is a minor mode and it is
+;; _off_ by default. If you want it to be on by default, use
+;; (setq-default filladapt-mode t)
+;;
+;; M-x filladapt-mode toggles Filladapt mode on/off in the current
+;; buffer.
+;;
+;; Use
+;; (add-hook 'text-mode-hook 'turn-on-filladapt-mode)
+;; to have Filladapt always enabled in Text mode.
+;;
+;; Use
+;; (add-hook 'c-mode-hook 'turn-off-filladapt-mode)
+;; to have Filladapt always disabled in C mode.
+;;
+;; In many cases, you can extend Filladapt by adding appropriate
+;; entries to the following three `defvar's. See `postscript-comment'
+;; or `texinfo-comment' as a sample of what needs to be done.

+jshint-mode
+=======
+
+Integrate [JSHint](http://jshint.com) into Emacs via a [node.js](http://nodejs.org) server.
+
+![example](https://github.com/daleharvey/jshint-mode/raw/master/example.png)
+
+jshint-mode was heavily inspired by Kevin Turners [lintnode](https://github.com/keturn/lintnode).
+
+Building
+========
+
+Install via [npm](http://npmjs.org/)
+
+ $ npm install jshint-mode
+
+or you can [download](https://github.com/daleharvey/jshint-mode/tarball/master) or clone
+
+ $ git clone git://github.com/daleharvey/jshint-mode.git
+
+Usage
+=====
+
+Add the configuration to your .emacs config file:
+
+ $jshint-emacs-path >> ~/.emacs
+
+or if you downloaded manually:
+
+ (add-to-list 'load-path "~/path/to/jshint-mode")
+ (require 'flymake-jshint)
+ (add-hook 'javascript-mode-hook
+ (lambda () (flymake-mode t)))
+
+You can use M-x flymake-mode to turn flymake of and on, if you want to turn it on be fault, add the following to your .emacs
+
+ ;; Turns on flymake for all files which have a flymake mode
+ (add-hook 'find-file-hook 'flymake-find-file-hook)

+/*
+ JSHINT is a global function. It takes two parameters.
+
+ var myResult = JSHINT(source, option);
+
+ The first parameter is either a string or an array of strings. If it is a
+ string, it will be split on '\n' or '\r'. If it is an array of strings, it
+ is assumed that each string represents one line. The source can be a
+ JavaScript text, or HTML text, or a JSON text, or a CSS text.
+
+ The second parameter is an optional object of options which control the
+ operation of JSHINT. Most of the options are booleans: They are all
+ optional and have a default value of false. One of the options, predef,
+ can be an array of names, which will be used to declare global variables,
+ or an object whose keys are used as global names, with a boolean value
+ that determines if they are assignable.
+
+ If it checks out, JSHINT returns true. Otherwise, it returns false.
+
+ If false, you can inspect JSHINT.errors to find out the problems.
+ JSHINT.errors is an array of objects containing these members:
+
+ {
+ line : The line (relative to 0) at which the lint was found
+ character : The character (relative to 0) at which the lint was found
+ reason : The problem
+ evidence : The text line in which the problem occurred
+ raw : The raw message before the details were inserted
+ a : The first detail
+ b : The second detail
+ c : The third detail
+ d : The fourth detail
+ }
+
+ If a fatal error was found, a null will be the last element of the
+ JSHINT.errors array.
+
+ You can request a Function Report, which shows all of the functions
+ and the parameters and vars that they use. This can be used to find
+ implied global variables and other problems. The report is in HTML and
+ can be inserted in an HTML <body>.
+
+ var myReport = JSHINT.report(limited);
+
+ If limited is true, then the report will be limited to only errors.
+
+ You can request a data structure which contains JSHint's results.
+
+ var myData = JSHINT.data();
+
+ It returns a structure with this form:
+
+ {
+ errors: [
+ {
+ line: NUMBER,
+ character: NUMBER,
+ reason: STRING,
+ evidence: STRING
+ }
+ ],
+ functions: [
+ name: STRING,

+ JSLINT is a global function. It takes two parameters.
+
+ var myResult = JSLINT(source, option);
+
+ The first parameter is either a string or an array of strings. If it is a
+ string, it will be split on '\n' or '\r'. If it is an array of strings, it
+ is assumed that each string represents one line. The source can be a
+ JavaScript text, or HTML text, or a Konfabulator text.
+
+ The second parameter is an optional object of options which control the
+ operation of JSLINT. Most of the options are booleans: They are all are
+ optional and have a default value of false.
+
+ If it checks out, JSLINT returns true. Otherwise, it returns false.
+
+ If false, you can inspect JSLINT.errors to find out the problems.
+ JSLINT.errors is an array of objects containing these members:
+
+ {
+ line : The line (relative to 0) at which the lint was found
+ character : The character (relative to 0) at which the lint was found
+ reason : The problem
+ evidence : The text line in which the problem occurred
+ raw : The raw message before the details were inserted
+ a : The first detail
+ b : The second detail
+ c : The third detail
+ d : The fourth detail
+ }
+
+ If a fatal error was found, a null will be the last element of the
+ JSLINT.errors array.
+
+ You can request a Function Report, which shows all of the functions
+ and the parameters and vars that they use. This can be used to find
+ implied global variables and other problems. The report is in HTML and
+ can be inserted in an HTML <body>.
+
+ var myReport = JSLINT.report(limited);
+
+ If limited is true, then the report will be limited to only errors.
+
+ You can request a data structure which contains JSLint's results.
+
+ var myData = JSLINT.data();
+
+ It returns a structure with this form:
+
+ {
+ errors: [
+ {
+ line: NUMBER,
+ character: NUMBER,
+ reason: STRING,
+ evidence: STRING
+ }
+ ],
+ functions: [

+# Formidable
+
+## Purpose
+
+A node.js module for parsing form data, especially file uploads.
+
+## Current status
+
+This module was developed for [Transloadit](http://transloadit.com/), a service focused on uploading
+and encoding images and videos. It has been battle-tested against hundreds of GB of file uploads from
+a big variety of clients and is considered production-ready.
+
+## Features
+
+* Fast (~500mb/sec), non-buffering multipart parser
+* Automatically writing file uploads to disk
+* Low memory footprint
+* Graceful error handling
+* Very high test coverage
+
+## Changelog
+
+### v1.0.2
+
+* Exclude node\_modules folder from git
+* Implement new `'aborted'` event
+* Fix files in example folder to work with recent node versions
+* Make gently a devDependency
+
+[See Commits](https://github.com/felixge/node-formidable/compare/v1.0.1...v1.0.2)
+
+### v1.0.1
+
+* Fix package.json to refer to proper main directory. (#68, Dean Landolt)
+
+[See Commits](https://github.com/felixge/node-formidable/compare/v1.0.0...v1.0.1)
+
+### v1.0.0
+
+* Add support for multipart boundaries that are quoted strings. (Jeff Craig)
+
+This marks the begin of the development on version 2.0 which will include
+several architecural improvements.
+
+[See Commits](https://github.com/felixge/node-formidable/compare/v0.9.11...v1.0.0)
+
+### v0.9.11
+
+* Emit `'progress'` event when receiving data, regardless of parsing it. (Tim Koschützki)
+* Use [W3C FileAPI Draft](http://dev.w3.org/2006/webapi/FileAPI/) properties for File class
+
+**Important:** The old property names of the File class will be removed in a
+future release.

+
+## Installation
+
+Via [npm](http://github.com/isaacs/npm):
+
+ npm install formidable@latest
+
+Manually:
+
+ git clone git://github.com/felixge/node-formidable.git formidable
+ vim my.js
+ # var formidable = require('./formidable');
+
+Note: Formidable requires [gently](http://github.com/felixge/node-gently) to run the unit tests, but you won't need it for just using the library.
+
+## Example
+
+Parse an incoming file upload.
+
+ var formidable = require('formidable'),
+ http = require('http'),
+
+ sys = require('sys');
+
+ http.createServer(function(req, res) {
+ if (req.url == '/upload' && req.method.toLowerCase() == 'post') {
+ // parse a file upload
+ var form = new formidable.IncomingForm();
+ form.parse(req, function(err, fields, files) {
+ res.writeHead(200, {'content-type': 'text/plain'});
+ res.write('received upload:\n\n');
+ res.end(sys.inspect({fields: fields, files: files}));
+ });
+ return;
+ }
+
+ // show a file upload form
+ res.writeHead(200, {'content-type': 'text/html'});
+ res.end(
+ '<form action="/upload" enctype="multipart/form-data" method="post">'+
+ '<input type="text" name="title"><br>'+
+ '<input type="file" name="upload" multiple="multiple"><br>'+
+ '<input type="submit" value="Upload">'+
+ '</form>'
+ );
+ });
+
+## API
+
+### formdiable.IncomingForm
+
+#### new formdiable.IncomingForm()
+
+Creates a new incoming form.
+
+#### incomingForm.encoding = 'utf-8'
+
+The encoding to use for incoming form fields.
+
+#### incomingForm.uploadDir = '/tmp'
+
+The directory for placing file uploads in. You can later on move them using `fs.rename()`.
+
+#### incomingForm.keepExtensions = false
+
+If you want the files written to `incomingForm.uploadDir` to include the extensions of the original files, set this property to `true`.
+
+#### incomingForm.type
+
+Either 'multipart' or 'urlencoded' depending on the incoming request.
+
+#### incomingForm.maxFieldsSize = 2 * 1024 * 1024
+
+Limits the amount of memory a field (not file) can allocate in bytes.
+I this value is exceeded, an `'error'` event is emitted. The default
+size is 2MB.
+
+#### incomingForm.bytesReceived
+
+The amount of bytes received for this form so far.
+
+#### incomingForm.bytesExpected
+
+The expected number of bytes in this form.
+
+#### incomingForm.parse(request, [cb])
+
+Parses an incoming node.js `request` containing form data. If `cb` is provided, all fields an files are collected and passed to the callback:
+
+ incomingForm.parse(req, function(err, fields, files) {
+ // ...
+ });
+
+#### incomingForm.onPart(part)
+
+You may overwrite this method if you are interested in directly accessing the multipart stream. Doing so will disable any `'field'` / `'file'` events processing which would occur otherwise, making you fully responsible for handling the processing.
+
+ incomingForm.onPart = function(part) {
+ part.addListener('data', function() {
+ // ...
+ });
+ }
+
+If you want to use formidable to only handle certain parts for you, you can do so:
+
+ incomingForm.onPart = function(part) {
+ if (!part.filename) {
+ // let formidable handle all non-file parts
+ incomingForm.handlePart(part);
+ }
+ }
+
+Check the code in this method for further inspiration.
+
+#### Event: 'progress' (bytesReceived, bytesExpected)
+
+Emitted after each incoming chunk of data that has been parsed. Can be used to roll your own progress bar.
+
+#### Event: 'field' (name, value)
+
+Emitted whenever a field / value pair has been received.
+
+#### Event: 'fileBegin' (name, file)
+
+Emitted whenever a new file is detected in the upload stream. Use this even if
+you want to stream the file to somewhere else while buffering the upload on
+the file system.
+
+#### Event: 'file' (name, file)
+
+Emitted whenever a field / file pair has been received. `file` is an instance of `File`.
+
+#### Event: 'error' (err)
+
+Emitted when there is an error processing the incoming form. A request that experiences an error is automatically paused, you will have to manually call `request.resume()` if you want the request to continue firing `'data'` events.
+
+#### Event: 'aborted'
+
+Emitted when the request was aborted by the user. Right now this can be due to a 'timeout' or 'close' event on the socket. In the future there will be a seperate 'timeout' event (needs a change in the node core).
+
+#### Event: 'end' ()
+
+Emitted when the entire request has been received, and all contained files have finished flushing to disk. This is a great place for you to send your response.
+
+### formdiable.File
+
+#### file.size = 0
+
+The size of the uploade file in bytes. If the file is still being uploaded (see `'fileBegin'` event), this property says how many bytes of the file have been written to disk yet.
+
+#### file.path = null
+
+The path this file is being written to. You can modify this in the `'fileBegin'` event in
+case you are unhappy with the way formidable generates a temporary path for your files.
+
+#### file.name = null
+
+The name this file had according to the uploading client.
+
+#### file.type = null
+
+The mime type of this file, according to the uploading client.
+
+#### file.lastModifiedDate = null
+
+A date object (or `null`) containing the time this file was last written to. Mostly
+here for compatiblity with the [W3C File API Draft](http://dev.w3.org/2006/webapi/FileAPI/).

+;; promela-mode.el --- major mode for editing PROMELA program files
+;; $Revision: 1.11 $ $Date: 2001/07/09 18:36:45 $ $Author: engstrom $
+
+;; Author: Eric Engstrom <eric.engstrom@honeywell.com>
+;; Maintainer: Eric Engstrom
+;; Keywords: spin, promela, tools
+
+;; Copyright (C) 1998-2003 Eric Engstrom / Honeywell Laboratories
+
+;; ... Possibly insert GPL here someday ...
+
+;;; Commentary:
+
+;; This file contains code for a GNU Emacs major mode for editing
+;; PROMELA (SPIN) program files.
+
+;; Type "C-h m" in Emacs (while in a buffer in promela-mode) for
+;; information on how to configure indentation and fontification,
+;; or look at the configuration variables below.
+
+;; To use, place promela-mode.el in a directory in your load-path.
+;; Then, put the following lines into your .emacs and promela-mode
+;; will be automatically loaded when editing a PROMELA program.
+
+;; (autoload 'promela-mode "promela-mode" "PROMELA mode" nil t)
+;; (setq auto-mode-alist
+;; (append
+;; (list (cons "\\.promela$" 'promela-mode)
+;; (cons "\\.spin$" 'promela-mode)
+;; (cons "\\.pml$" 'promela-mode)
+;; ;; (cons "\\.other-extensions$" 'promela-mode)
+;; )
+;; auto-mode-alist))
+
+;; If you wish for promela-mode to be used for files with other
+;; extensions you add your own patterned after the code above.
+
+;; Note that promela-mode adhears to the font-lock "standards" and
+;; defines several "levels" of fontification or colorization. The
+;; default is fairly gaudy, so I can imagine that some folks would
+;; like a bit less. FMI: see `font-lock-maximum-decoration'
+
+;; This mode is known to work under the following versions of emacs:
+;; - XEmacs: 19.16, 20.x, 21.x
+;; - FSF/GNU Emacs: 19.34
+;; - NTEmacs (FSF): 20.[67]
+;; That is not to say there are no bugs specific to one of those versions :-)
+
+;; Please send any comments, bugs, patches or other requests to
+;; Eric Engstrom at engstrom@htc.honeywell.com
+
+;; To-Do:
+;; - compile/syntax-check/verify? (suggested by R.Goldman)
+;; - indentation - splitting lines at logical operators (M. Rangarajan)
+;; [ This might "devolve" to indentation after "->" or ";"
+;; being as is, but anything else indent even more? ]
+;; :: SomeReallyLongArrayRef[this].typedefField != SomeReallyLongConstant -> /* some-comment */
+;; [ Suggestion would be to break the first line after the !=, therefore: ]
+;; :: SomeReallyLongArrayRef[this].typedefField
+;; != SomeReallyLongConstant -> /* some-comment */
+;; [ at this point I'm not so sure about this change... EE: 2001/05/19 ]

+;; - commented out the compilation / syntax check stuff for now
+;;
+;; Revision 1.8 2001/05/22 16:18:49 engstrom
+;; - Munched history in preparation for first non-Honeywell release
+;; - Added "levels" of fontification to be controlled by the std. variable:
