<h1>Pandoc PDF Builder</h1>
<hr>
<p>Upload a source document in Markdown (.md) format plus any images to be included.</p>
<p>This app will process them using Pandoc (https://pandoc.com) with a tweaked <a href="https://github.com/Wandmalfarbe/pandoc-latex-template">eisvogel template</a> and <a href="https://www.ctan.org/tex-archive/graphics/awesomebox">awesomebox.sty</a> to create a beautiful PDF, without the hassle of manual formatting in Word etc.</p>
<p><strong>THIS IS IN ALPHA STATUS : STILL IN DEVELOPMENT.</strong></p>
<hr>
<p>Click here to upload (1) a .md Markdown file (2) any included images</p>
<form action="fileupload" method="post" enctype="multipart/form-data">
<input type="file" name="filetoupload"><br><br>
<input type="submit" value="Upload">
</form>
<br>
<hr>
<h3>Background</h3>
<p>This app is a custom (i.e. not officially developed or maintained) app packaged for Cloudron.</p>
<p>It packages an instance of the excellent document conversion utility <a href="https://pandoc.org">Pandoc</a>.</p>
<p>Pandoc only runs from the command line. By packaging it into a web app, a consistent publishing environment can be maintained in a single location (avoiding multiple local installs which might change over time) and be accessible from any device, even without Pandoc and its utilities installed.</p>
<p>It is based on Cloudron's tutorial-supervisor app and the "pandoc docker" app from <a href="https://github.com/vpetersson/docker-pandoc">Viktor Petersson</a>.</p>
<p>Once the source Markdown and related images files are uploaded, click the button to process them.</p>
<p>The app will create a PDF, which must be downloaded to the local computer, as it cannot be retrieved later.</p>
<p>The source Markdown file will be moved to /app/data/done (in future version, it will be deleted).</p>
<p>Image files will not be moved, in case they are required for subsequent PDF creations, e.g.on updating and re-uploading the source Markdown file.</p>
<p>NB : currently source image files might be overwritten by other users of the app uploading a file of the same name but different content. Your document will then be. reated with the wrong image. If so, re-upload them and retry. This issue will be addressed in a future version.</p>

## 2.0.6
Version 2.0.4 adds support for React Native by clarifying in package.json that
the browser environment does not support Node.js domains.
Why this is necessary, we leave as an exercise for the user.
## 2.0.3
Version 2.0.3 fixes a bug when adjusting the capacity of the task queue.
## 2.0.1-2.02
Version 2.0.1 fixes a bug in the way redirects were expressed that affected the
function of Browserify, but which Mr would tolerate.
## 2.0.0
Version 2 of ASAP is a full rewrite with a few salient changes.
First, the ASAP source is CommonJS only and designed with [Browserify][] and
[Browserify-compatible][Mr] module loaders in mind.
[Browserify]: https://github.com/substack/node-browserify
[Mr]: https://github.com/montagejs/mr
The new version has been refactored in two dimensions.
Support for Node.js and browsers have been separated, using Browserify
redirects and ASAP has been divided into two modules.
The "raw" layer depends on the tasks to catch thrown exceptions and unravel
Node.js domains.
The full implementation of ASAP is loadable as `require("asap")` in both Node.js
and browsers.
The raw layer that lacks exception handling overhead is loadable as
`require("asap/raw")`.
The interface is the same for both layers.
Tasks are no longer required to be functions, but can rather be any object that
implements `task.call()`.
With this feature you can recycle task objects to avoid garbage collector churn
and avoid closures in general.
The implementation has been rigorously documented so that our successors can
understand the scope of the problem that this module solves and all of its
nuances, ensuring that the next generation of implementations know what details
are essential.
- [asap.js](https://github.com/kriskowal/asap/blob/master/asap.js)
- [raw.js](https://github.com/kriskowal/asap/blob/master/raw.js)
- [browser-asap.js](https://github.com/kriskowal/asap/blob/master/browser-asap.js)
- [browser-raw.js](https://github.com/kriskowal/asap/blob/master/browser-raw.js)
The new version has also been rigorously tested across a broad spectrum of
browsers, in both the window and worker context.
The following charts capture the browser test results for the most recent
release.
The first chart shows test results for ASAP running in the main window context.
The second chart shows test results for ASAP running in a web worker context.
Test results are inconclusive (grey) on browsers that do not support web
workers.
These data are captured automatically by [Continuous
Integration][].

# ASAP
[![Build Status](https://travis-ci.org/kriskowal/asap.png?branch=master)](https://travis-ci.org/kriskowal/asap)
Promise and asynchronous observer libraries, as well as hand-rolled callback
programs and libraries, often need a mechanism to postpone the execution of a
callback until the next available event.
(See [Designing API’s for Asynchrony][Zalgo].)
The `asap` function executes a task **as soon as possible** but not before it
returns, waiting only for the completion of the current event and previously
scheduled tasks.
```javascript
asap(function () {
// ...
});
```
[Zalgo]: http://blog.izs.me/post/59142742143/designing-apis-for-asynchrony
This CommonJS package provides an `asap` module that exports a function that
executes a task function *as soon as possible*.
ASAP strives to schedule events to occur before yielding for IO, reflow,
or redrawing.
Each event receives an independent stack, with only platform code in parent
frames and the events run in the order they are scheduled.
ASAP provides a fast event queue that will execute tasks until it is
empty before yielding to the JavaScript engine's underlying event-loop.
When a task gets added to a previously empty event queue, ASAP schedules a flush
event, preferring for that event to occur before the JavaScript engine has an
opportunity to perform IO tasks or rendering, thus making the first task and
subsequent tasks semantically indistinguishable.
ASAP uses a variety of techniques to preserve this invariant on different
versions of browsers and Node.js.
By design, ASAP prevents input events from being handled until the task
queue is empty.
If the process is busy enough, this may cause incoming connection requests to be
dropped, and may cause existing connections to inform the sender to reduce the
transmission rate or stall.
ASAP allows this on the theory that, if there is enough work to do, there is no
sense in looking for trouble.
As a consequence, ASAP can interfere with smooth animation.
If your task should be tied to the rendering loop, consider using
`requestAnimationFrame` instead.
A long sequence of tasks can also effect the long running script dialog.
If this is a problem, you may be able to use ASAP’s cousin `setImmediate` to
break long processes into shorter intervals and periodically allow the browser
to breathe.
`setImmediate` will yield for IO, reflow, and repaint events.
It also returns a handler and can be canceled.
For a `setImmediate` shim, consider [YuzuJS setImmediate][setImmediate].
[setImmediate]: https://github.com/YuzuJS/setImmediate
Take care.
ASAP can sustain infinite recursive calls without warning.
It will not halt from a stack overflow, and it will not consume unbounded
memory.
This is behaviorally equivalent to an infinite loop.
Just as with infinite loops, you can monitor a Node.js process for this behavior
with a heart-beat signal.
As with infinite loops, a very small amount of caution goes a long way to
avoiding problems.
```javascript
function loop() {
asap(loop);
}
loop();
```
In browsers, if a task throws an exception, it will not interrupt the flushing
of high-priority tasks.
The exception will be postponed to a later, low-priority event to avoid
slow-downs.
In Node.js, if a task throws an exception, ASAP will resume flushing only if—and
only after—the error is handled by `domain.on("error")` or
`process.on("uncaughtException")`.
## Raw ASAP
Checking for exceptions comes at a cost.
The package also provides an `asap/raw` module that exports the underlying
implementation which is faster but stalls if a task throws an exception.
This internal version of the ASAP function does not check for errors.
If a task does throw an error, it will stall the event queue unless you manually
call `rawAsap.requestFlush()` before throwing the error, or any time after.
In Node.js, `asap/raw` also runs all tasks outside any domain.
If you need a task to be bound to your domain, you will have to do it manually.
```js
if (process.domain) {
task = process.domain.bind(task);
}
rawAsap(task);
```
## Tasks
A task may be any object that implements `call()`.
A function will suffice, but closures tend not to be reusable and can cause
garbage collector churn.
Both `asap` and `rawAsap` accept task objects to give you the option of
recycling task objects or using higher callable object abstractions.
See the `asap` source for an illustration.
## Compatibility
ASAP is tested on Node.js v0.10 and in a broad spectrum of web browsers.
The following charts capture the browser test results for the most recent
release.
The first chart shows test results for ASAP running in the main window context.
The second chart shows test results for ASAP running in a web worker context.
Test results are inconclusive (grey) on browsers that do not support web
workers.
These data are captured automatically by [Continuous
Integration][].

## Caveats
When a task is added to an empty event queue, it is not always possible to
guarantee that the task queue will begin flushing immediately after the current
event.
However, once the task queue begins flushing, it will not yield until the queue
is empty, even if the queue grows while executing tasks.
The following browsers allow the use of [DOM mutation observers][] to access
the HTML [microtask queue][], and thus begin flushing ASAP's task queue
immediately at the end of the current event loop turn, before any rendering or
IO:
[microtask queue]: http://www.whatwg.org/specs/web-apps/current-work/multipage/webappapis.html#microtask-queue
[DOM mutation observers]: http://dom.spec.whatwg.org/#mutation-observers
- Android 4–4.3
- Chrome 26–34
- Firefox 14–29
- Internet Explorer 11
- iPad Safari 6–7.1
- iPhone Safari 7–7.1
- Safari 6–7
In the absense of mutation observers, there are a few browsers, and situations
like web workers in some of the above browsers, where [message channels][]
would be a useful way to avoid falling back to timers.
Message channels give direct access to the HTML [task queue][], so the ASAP
task queue would flush after any already queued rendering and IO tasks, but
without having the minimum delay imposed by timers.
However, among these browsers, Internet Explorer 10 and Safari do not reliably
dispatch messages, so they are not worth the trouble to implement.
[message channels]: http://www.whatwg.org/specs/web-apps/current-work/multipage/web-messaging.html#message-channels
[task queue]: http://www.whatwg.org/specs/web-apps/current-work/multipage/webappapis.html#concept-task
- Internet Explorer 10
- Safair 5.0-1
- Opera 11-12
In the absense of mutation observers, these browsers and the following browsers
all fall back to using `setTimeout` and `setInterval` to ensure that a `flush`
occurs.
The implementation uses both and cancels whatever handler loses the race, since
`setTimeout` tends to occasionally skip tasks in unisolated circumstances.
Timers generally delay the flushing of ASAP's task queue for four milliseconds.
- Firefox 3–13
- Internet Explorer 6–10
- iPad Safari 4.3
- Lynx 2.8.7
## Heritage
ASAP has been factored out of the [Q][] asynchronous promise library.
It originally had a naïve implementation in terms of `setTimeout`, but
[Malte Ubl][NonBlocking] provided an insight that `postMessage` might be
useful for creating a high-priority, no-delay event dispatch hack.
Since then, Internet Explorer proposed and implemented `setImmediate`.
Robert Katić began contributing to Q by measuring the performance of
the internal implementation of `asap`, paying particular attention to
error recovery.
Domenic, Robert, and Kris Kowal collectively settled on the current strategy of
unrolling the high-priority event queue internally regardless of what strategy
we used to dispatch the potentially lower-priority flush event.
Domenic went on to make ASAP cooperate with Node.js domains.
[Q]: https://github.com/kriskowal/q
[NonBlocking]: http://www.nonblocking.io/2011/06/windownexttick.html
For further reading, Nicholas Zakas provided a thorough article on [The
Case for setImmediate][NCZ].
[NCZ]: http://www.nczonline.net/blog/2013/07/09/the-case-for-setimmediate/
Ember’s RSVP promise implementation later [adopted][RSVP ASAP] the name ASAP but
further developed the implentation.
Particularly, The `MessagePort` implementation was abandoned due to interaction
[problems with Mobile Internet Explorer][IE Problems] in favor of an
implementation backed on the newer and more reliable DOM `MutationObserver`
interface.
These changes were back-ported into this library.
[IE Problems]: https://github.com/cujojs/when/issues/197
[RSVP ASAP]: https://github.com/tildeio/rsvp.js/blob/cddf7232546a9cf858524b75cde6f9edf72620a7/lib/rsvp/asap.js
In addition, ASAP factored into `asap` and `asap/raw`, such that `asap` remained
exception-safe, but `asap/raw` provided a tight kernel that could be used for
tasks that guaranteed that they would not throw exceptions.
This core is useful for promise implementations that capture thrown errors in
rejected promises and do not need a second safety net.
At the same time, the exception handling in `asap` was factored into separate
implementations for Node.js and browsers, using the the [Browserify][Browser
Config] `browser` property in `package.json` to instruct browser module loaders
and bundlers, including [Browserify][], [Mr][], and [Mop][], to use the
browser-only implementation.
[Browser Config]: https://gist.github.com/defunctzombie/4339901

Create and parse HTTP `Content-Disposition` header
## Installation
```sh
$ npm install content-disposition
```
## API
```js
var contentDisposition = require('content-disposition')
```
### contentDisposition(filename, options)
Create an attachment `Content-Disposition` header value using the given file name,
if supplied. The `filename` is optional and if no file name is desired, but you
want to specify `options`, set `filename` to `undefined`.
```js
res.setHeader('Content-Disposition', contentDisposition('∫ maths.pdf'))
```
**note** HTTP headers are of the ISO-8859-1 character set. If you are writing this
header through a means different from `setHeader` in Node.js, you'll want to specify
the `'binary'` encoding in Node.js.
#### Options
`contentDisposition` accepts these properties in the options object.
##### fallback
If the `filename` option is outside ISO-8859-1, then the file name is actually
stored in a supplemental field for clients that support Unicode file names and
a ISO-8859-1 version of the file name is automatically generated.
This specifies the ISO-8859-1 file name to override the automatic generation or
disables the generation all together, defaults to `true`.
- A string will specify the ISO-8859-1 file name to use in place of automatic
generation.
- `false` will disable including a ISO-8859-1 file name and only include the
Unicode version (unless the file name is already ISO-8859-1).
- `true` will enable automatic generation if the file name is outside ISO-8859-1.
If the `filename` option is ISO-8859-1 and this option is specified and has a
different value, then the `filename` option is encoded in the extended field
and this set as the fallback field, even though they are both ISO-8859-1.
##### type
Specifies the disposition type, defaults to `"attachment"`. This can also be
`"inline"`, or any other value (all values except inline are treated like
`attachment`, but can convey additional information if both parties agree to
it). The type is normalized to lower-case.
### contentDisposition.parse(string)
```js
var disposition = contentDisposition.parse('attachment; filename="EURO rates.txt"; filename*=UTF-8\'\'%e2%82%ac%20rates.txt')
```
Parse a `Content-Disposition` header string. This automatically handles extended
("Unicode") parameters by decoding them and providing them under the standard
parameter name. This will return an object with the following properties (examples
are shown for the string `'attachment; filename="EURO rates.txt"; filename*=UTF-8\'\'%e2%82%ac%20rates.txt'`):
- `type`: The disposition type (always lower case). Example: `'attachment'`
- `parameters`: An object of the parameters in the disposition (name of parameter
always lower case and extended versions replace non-extended versions). Example:
`{filename: "€ rates.txt"}`
## Examples
### Send a file for download
```js
var contentDisposition = require('content-disposition')
var destroy = require('destroy')
var fs = require('fs')
var http = require('http')
var onFinished = require('on-finished')
var filePath = '/path/to/public/plans.pdf'
http.createServer(function onRequest (req, res) {
// set headers
res.setHeader('Content-Type', 'application/pdf')
res.setHeader('Content-Disposition', contentDisposition(filePath))
// send file
var stream = fs.createReadStream(filePath)
stream.pipe(res)
onFinished(res, function () {
destroy(stream)
})
})
```
## Testing
```sh
$ npm test
```
