Description
-----------
Python ESC/POS is a library which lets the user have access to all those printers handled
by ESC/POS commands, as defined by Epson, from a Python application.
The library tries to implement the functions provided by the ESC/POS-commandset and supports sending text, images,
barcodes and qr-codes to the printer.
Text can be aligned/justified and fonts can be changed by size, type and weight.
Also, this module handles some hardware functionalities like cutting paper, control characters, printer reset
and similar functions.
Since supported commands differ from printer to printer the software tries to automatically apply the right
settings for the printer that you set. These settings are handled by
`escpos-printer-db <https://github.com/receipt-print-hq/escpos-printer-db>`_ which is also used in
`escpos-php <https://github.com/mike42/escpos-php>`_.
Dependencies
------------
This library makes use of:
* `pyusb <https://github.com/walac/pyusb>`_ for USB-printers
* `Pillow <https://github.com/python-pillow/Pillow>`_ for image printing
* `qrcode <https://github.com/lincolnloop/python-qrcode>`_ for the generation of QR-codes
* `pyserial <https://github.com/pyserial/pyserial>`_ for serial printers
* `python-barcode <https://github.com/WhyNotHugo/python-barcode>`_ for the generation of barcodes
Documentation and Usage
-----------------------
The basic usage is:
.. code:: python
from escpos.printer import Usb
""" Seiko Epson Corp. Receipt Printer (EPSON TM-T88III) """
p = Usb(0x04b8, 0x0202, 0, profile="TM-T88III")
p.text("Hello World\n")
p.image("logo.gif")
p.barcode('1324354657687', 'EAN13', 64, 2, '', '')
p.cut()
Another example based on the Network printer class:
.. code:: python
from escpos.printer import Network
kitchen = Network("192.168.1.100") #Printer IP Address
kitchen.text("Hello World\n")
kitchen.barcode('1324354657687', 'EAN13', 64, 2, '', '')
kitchen.cut()
Another example based on the Serial printer class:
.. code:: python
from escpos.printer import Serial
""" 9600 Baud, 8N1, Flow Control Enabled """
p = Serial(devfile='/dev/tty.usbserial',
baudrate=9600,
bytesize=8,
parity='N',
stopbits=1,
timeout=1.00,
dsrdtr=True)
p.text("Hello World\n")
p.qr("You can readme from your smartphone")
p.cut()
The full project-documentation is available on `Read the Docs <https://python-escpos.readthedocs.io>`_.

Contributing
************
This project is open to any kind of contribution. You can help with improving the documentation, adding fixes to the
code, providing test cases in code or as a description or just spreading the word. Please feel free to create an
issue or pull request.
In order to reduce the amount of work for everyone please try to adhere to good practice.
The pull requests and issues will be prefilled with templates. Please fill in your information where applicable.
This project uses `semantic versioning <https://semver.org/>`_ and tries to adhere to the proposed rules as
well as possible.
Author-list
-----------
This project keeps a list of authors. This can be auto-generated by calling `./doc/generate-authors.sh`.
When contributing the first time, please include a commit with the output of this script in place.
Otherwise the integration-check will fail.
When you change your username or mail-address, please also update the `.mailmap` and the authors-list.
You can find a good documentation on the mapping-feature in the `documentation of git-shortlog <https://git-scm.com/docs/git-shortlog#_mapping_authors>`_.
Style-Guide
-----------
When writing code please try to stick to these rules.
PEP8
^^^^
The entire codebase adheres to the rules of PEP8.
These rules are enforced by running `flake8` in the integration-checks.
Please adhere to these rules as your contribution can only be merged if the check succeeds.
You can use flake8 or similar tools locally in order to check your code.
Apart from that the travis-log and the check by Landscape will provide you with hints.
GIT
^^^
The master-branch contains the main development of the project. A release to PyPi is marked with a tag
corresponding to the version. Issues are closed when they have been resolved by merging into the master-branch.
When you have a change to make, begin by creating a new branch from the HEAD of `python-escpos/master`.
Please try to group your commits into logical units. If you need to tidy up your branch, you can make use of a
git feature called an 'interactive rebase' before making a pull request. A small, self-contained change-set is
easier to review, and improves the chance of your code being merged.
Please also make sure that before creating your PR, your branch is rebased on a recent commit or you merged a recent
commit into your branch. This way you can ensure that your PR is without merge conflicts.
Docstrings
^^^^^^^^^^
This project tries to have a good documentation.
Please add a docstring to every method and class. Have a look at existing methods and classes for the style.
We use basically standard rst-docstrings for Sphinx.
Test
^^^^
Try to write tests whenever possible. Our goal for the future is 100% coverage.
We are currently using `nose` but might change in the future.
You can copy the structure from other testcases. Please remember to adapt the docstrings.
Further reading
^^^^^^^^^^^^^^^
For further best practices and hints on contributing please see the
`contribution-guide <https://www.contribution-guide.org/>`_. Should there be any contradictions between this guide
and the linked one, please stick to this text.
Aside from that feel free to create an issue or write an email if anything is unclear.
Thank you for your contribution!

This method allows to print barcodes. The rendering of the barcode is done by the printer and therefore has to
be supported by the unit. By default, this method will check whether your barcode text is correct, that is
the characters and lengths are supported by ESCPOS. Call the method with `check=False` to disable the check, but
note that uncorrect barcodes may lead to unexpected printer behaviour.
There are two forms of the barcode function. Type A is default but has fewer barcodes,
while type B has some more to choose from.
Use the parameters `height` and `width` for adjusting of the barcode size. Please take notice that the barcode
will not be printed if it is outside of the printable area. (Which should be impossible with this method, so
this information is probably more useful for debugging purposes.)
.. todo:: On TM-T88II width from 1 to 6 is accepted. Try to acquire command reference and correct the code.
.. todo:: Supplying pos does not have an effect for every barcode type. Check and document for which types this
is true.
If you do not want to center the barcode you can call the method with `align_ct=False`, which will disable
automatic centering. Please note that when you use center alignment, then the alignment of text will be changed
automatically to centered. You have to manually restore the alignment if necessary.

be of help if the printer does not support types that others do.)

Printers
********
:Last Reviewed: 2017-01-25
As of now there are 5 different type of printer implementations.
USB
---
The USB-class uses pyusb and libusb to communicate with USB-based
printers. Note that this driver is not suited for USB-to-Serial-adapters
and similiar devices, but only for those implementing native USB.
.. autoclass:: escpos.printer.Usb
:members:
:special-members:
:member-order: bysource
:noindex:
Serial
------
This driver uses pyserial in order to communicate with serial devices.
If you are using an USB-based adapter to connect to the serial port,
then you should also use this driver.
The configuration is often based on DIP-switches that you can set on your
printer. For the hardware-configuration please refer to your printer's manual.
.. autoclass:: escpos.printer.Serial
:members:
:special-members:
:member-order: bysource
:noindex:
Network
-------
This driver is based on the socket class.
.. autoclass:: escpos.printer.Network
:members:
:special-members:
:member-order: bysource
:noindex:
Troubleshooting
^^^^^^^^^^^^^^^
Problems with a network-attached printer can have numerous causes. Make sure that your device has a proper IP address.
Often you can check the IP address by triggering the self-test of the device. As a next step try to send text
manually to the device. You could use for example:
::
echo "OK\n" | nc IPADDRESS 9100
# the port number is often 9100
As a last resort try to reset the interface of the printer. This should be described in its manual.
File
----
This printer "prints" just into a file-handle. Especially on \*nix-systems this comes very handy.
.. autoclass:: escpos.printer.File
:members:
:special-members:
:member-order: bysource
:noindex:
Dummy
-----
The Dummy-printer is mainly for testing- and debugging-purposes. It stores
all of the "output" as raw ESC/POS in a string and returns that.

Escpos class
------------
The core part of this libraries API is the Escpos class.
You use it by instantiating a :doc:`printer <printers>` which is a child of Escpos.
The following methods are available:

Printing Barcodes
-----------------
:Last Reviewed: 2016-07-31
Most ESC/POS-printers implement barcode-printing.
The barcode-commandset is implemented in the barcode-method.
For a list of compatible barcodes you should check the manual of your printer.
As a rule of thumb: even older Epson-models support most 1D-barcodes.
To be sure just try some implementations and have a look at the notices below.
barcode-method
~~~~~~~~~~~~~~
The barcode-method is rather low-level and orients itself on the implementation of ESC/POS.
In the future this class could be supplemented by a high-level class that helps the user generating the payload.
.. py:currentmodule:: escpos.escpos
.. automethod:: Escpos.barcode
:noindex:
CODE128
~~~~~~~
Code128 barcodes need a certain format.
For now the user has to make sure that the payload is correct.
For alphanumeric CODE128 you have to preface your payload with `{B`.
.. code-block:: Python
from escpos.printer import Dummy, Serial
p = Serial()
# print CODE128 012ABCDabcd
p.barcode("{B012ABCDabcd", "CODE128", function_type="B")
A very good description on CODE128 is also on `Wikipedia <https://en.wikipedia.org/wiki/Code_128>`_.

Installation
************
:Last Reviewed: 2016-07-23
Installation with PIP
---------------------
Installation should be rather straight-forward. python-escpos is on PyPi, so you can simply enter:
::
pip install python-escpos
This should install all necessary dependencies. Apart from that python-escpos should also be
available as a Debian package. If you want to always benefit from the newest stable releases you should probably
install from PyPi.
Setup udev for USB-Printers
---------------------------
1. Get the *Product ID* and *Vendor ID* from the lsusb command
``# lsusb Bus 002 Device 001: ID 1a2b:1a2b Device name``
2. Create a udev rule to let users belonging to *dialout* group use the
printer. You can create the file
``/etc/udev/rules.d/99-escpos.rules`` and add the following:
``SUBSYSTEM=="usb", ATTRS{idVendor}=="1a2b", ATTRS{idProduct}=="1a2b", MODE="0664", GROUP="dialout"``
Replace *idVendor* and *idProduct* hex numbers with the ones that you
got from the previous step. Note that you can either, add yourself to
"dialout" group, or use another group you already belongs instead
"dialout" and set it in the ``GROUP`` parameter in the above rule.
3. Restart udev ``# sudo service udev restart`` In some new systems it
is done with ``# sudo udevadm control --reload``
Enabling tab-completion in CLI
------------------------------
python-escpos has a CLI with tab-completion. This is realised with ``argcomplete``.
In order for this to work you have to enable tab-completion, which is described in
the `manual of argcomplete <https://argcomplete.readthedocs.io>`__.
If you only want to enable it for python-escpos, or global activation does not work, try this:
::
eval "$(register-python-argcomplete python-escpos)"

Raspberry Pi
************
:Last Reviewed: 2017-01-05
This instructions were tested on Raspbian Jessie.
.. warning:: You should **never** directly connect an printer with RS232-interface (serial port) directly to
a Raspberry PI or similar interface (e.g. those simple USB-sticks without encasing). Those interfaces are
based on 5V- or 3,3V-logic (the latter in the case of Raspberry PI). Classical RS232 uses 12V-logic and would
**thus destroy your interface**. Connect both systems with an appropriate *level shifter*.
Dependencies
------------
First, install the packages available on Raspbian.
::
sudo apt-get install python3 python3-setuptools python3-pip libjpeg8-dev
Installation
------------
You can install by using pip3.
::
sudo pip3 install --upgrade pip
sudo pip3 install python-escpos
Run
---
You need sudo and python3 to run your program.
::
sudo python3 your-program.py
Now you can attach your printer and and test it with the example code in the project's set of examples.
You can find that in the `project-repository <https://github.com/python-escpos/python-escpos>`__.
For more details on this check the :doc:`installation-manual <installation>`.

Usage
*****
:Last Reviewed: 2017-06-10
Define your printer
-------------------
USB printer
^^^^^^^^^^^
Before creating your Python ESC/POS printer instance, consult the system to obtain
the printer parameters. This is done with the 'lsusb' command.
Run the command and look for the "Vendor ID" and "Product ID" and write
down the values. These values are displayed just before the name
of the device with the following format:
::
xxxx:xxxx
Example:
::
# lsusb
Bus 002 Device 001: ID 04b8:0202 Epson ...
Write down the the values in question, then issue the following command
so you can get the "Interface" number and "End Point"
::
# lsusb -vvv -d xxxx:xxxx | grep iInterface
iInterface 0
# lsusb -vvv -d xxxx:xxxx | grep bEndpointAddress | grep OUT
bEndpointAddress 0x01 EP 1 OUT
The first command will yield the "Interface" number that must be handy
to have and the second yields the "Output Endpoint" address.
**USB Printer initialization**
::
p = printer.Usb(0x04b8,0x0202)
By default the "Interface" number is "0" and the "Output Endpoint"
address is "0x01". If you have other values then you can define them on
your instance. So, assuming that we have another printer, CT-S2000,
manufactured by Citizen (with "Vendor ID" of 2730 and "Product ID" of 0fff)
where in\_ep is on 0x81 and out\_ep=0x02, then the printer definition should
look like:
**Generic USB Printer initialization**
::
p = printer.Usb(0x2730, 0x0fff, 0, 0x81, 0x02)
Network printer
^^^^^^^^^^^^^^^
You only need the IP of your printer, either because it is getting its
IP by DHCP or you set it manually.
**Network Printer initialization**
::
p = printer.Network("192.168.1.99")
Serial printer
^^^^^^^^^^^^^^
Most of the default values set by the DIP switches for the serial
printers, have been set as default on the serial printer class, so the
only thing you need to know is which serial port the printer is connected
to.
**Serial printer initialization**
::
p = printer.Serial("/dev/tty0")
# on a Windows OS serial devices are typically accessible as COM
p = printer.Serial("COM1")
Other printers
^^^^^^^^^^^^^^
Some printers under `/dev` can't be used or initialized with any of the
methods described above. Usually, those are printers used by printcap,
however, if you know the device name, you could try to initialize by
passing the device node name.
::
p = printer.File("/dev/usb/lp1")
The default is "/dev/usb/lp0", so if the printer is located on that
node, then you don't necessary need to pass the node name.
Define your instance
--------------------
The following example demonstrates how to initialize the Epson TM-TI88IV
on a USB interface.
::
from escpos import *
""" Seiko Epson Corp. Receipt Printer M129 Definitions (EPSON TM-T88IV) """
p = printer.Usb(0x04b8,0x0202)
# Print text
p.text("Hello World\n")
# Print image
p.image("logo.gif")
# Print QR Code
p.qr("You can readme from your smartphone")
# Print barcode
p.barcode('1324354657687','EAN13',64,2,'','')
# Cut paper
p.cut()
Configuration File
------------------
You can create a configuration file for python-escpos. This will
allow you to use the CLI, and skip some setup when using the library
programmatically.
The default configuration file is named ``config.yaml`` and uses the YAML
format. For windows it is probably at::
%appdata%/python-escpos/config.yaml
And for linux::
$HOME/.config/python-escpos/config.yaml
If you aren't sure, run::
from escpos import config
c = config.Config()
c.load()
If it can't find the configuration file in the default location, it will tell
you where it's looking. You can always pass a path, or a list of paths, to
the ``load()`` method.
To load the configured printer, run::
from escpos import config
c = config.Config()
printer = c.printer()
The printer section
^^^^^^^^^^^^^^^^^^^
The ``printer`` configuration section defines a default printer to create.
The only required parameter is ``type``. The value of this has to be one of the
printers defined in :doc:`/user/printers`.
The rest of the given parameters will be passed on to the initialization of the printer class.
Use these to overwrite the default values as specified in :doc:`/user/printers`.
This implies that the parameters have to match the parameter-names of the respective printer class.
An example file printer::
printer:
type: File
devfile: /dev/someprinter
And for a network printer::
printer:
type: Network
host: 127.0.0.1
port: 9000
An USB-printer could be defined by::
printer:
type: Usb
idVendor: 0x1234
idProduct: 0x5678
in_ep: 0x66
out_ep: 0x01
Printing text right
-------------------
Python-escpos is designed to accept unicode.
For normal usage you can simply pass your text to the printers ``text()``-function. It will automatically guess
the right codepage and then send the encoded data to the printer. If this feature does not work, please try to
isolate the error and then create an issue on the GitHub project page.
If you want or need to you can manually set the codepage. For this please use the ``charcode()``-function. You can set
any key-value that is in ``CHARCODE``. If something is wrong, an ``CharCodeError`` will be raised.
After you have manually set the codepage the printer won't change it anymore. You can revert to normal behaviour
by setting charcode to ``AUTO``.
Advanced Usage: Print from binary blob
--------------------------------------
Imagine you have a file with ESC/POS-commands in binary form. This could be useful for testing capabilities of your
printer with a known working combination of commands.
You can print this data with the following code, using the standard methods of python-escpos. (This is an
advantage of the fact that `_raw()` accepts binary strings.)
::
from escpos import printer
p = printer.Serial() # adapt this to your printer model
file = open("binary-blob.bin", "rb") # read in the file containing your commands in binary-mode
data = file.read()
file.close()
p._raw(data)
That's all, the printer should then print your data. You can also use this technique to let others reproduce an issue
that you have found. (Just "print" your commands to a File-printer on your local filesystem.)
However, please keep in mind, that often it is easier and better to just supply the code that you are using.
Here you can download an example, that will print a set of common barcodes:
* :download:`barcode.bin </download/barcode.bin>` by `@mike42 <https://github.com/mike42>`_
Advanced Usage: change capabilities-profile
-------------------------------------------
Packaged together with the escpos-code is a capabilities-file. This file in
JSON-format describes the capabilities of different printers. It is developed and hosted in
`escpos-printer-db <https://github.com/receipt-print-hq/escpos-printer-db>`_.
Certain applications like the usage of `cx_freeze <https://cx-freeze.readthedocs.io>`_ might change the
packaging structure. This leads to the capabilities-profile not being found.
In this case you can use the environment-variable `ESCPOS_CAPABILITIES_FILE`.
The following code is an example.
.. code-block:: shell
# use packaged capabilities-profile
python-escpos cut
# use capabilities-profile that you have put in /usr/python-escpos
export ESCPOS_CAPABILITIES_FILE=/usr/python-escpos/capabilities.json
python-escpos cut
# use packaged file again
unset ESCPOS_CAPABILITIES_FILE
python-escpos cut
Hint: preprocess printing
-------------------------
Printing images directly to the printer is rather slow.
One factor that slows down the process is the transmission over e.g. serial port.
Apart from configuring your printer to use the maximum baudrate (in the case of serial-printers), there is not much
that you can do.
However you could use the :py:class:`escpos.printer.Dummy`-printer to preprocess your image.
This is probably best explained by an example:
.. code-block:: Python
from escpos.printer import Serial, Dummy
p = Serial()
d = Dummy()
# create ESC/POS for the print job, this should go really fast
d.text("This is my image:\n")
d.image("funny_cat.png")
d.cut()
# send code to printer
p._raw(d.output)
This way you could also store the code in a file and print it later.
You could then for example print the code from another process than your main-program and thus reduce the waiting time.
(Of course this will not make the printer print faster.)

## Quick start
**NOTE: There are some breaking changes related to form flow and url initialization in the recent release of 1.2-M1. The user guide will be modified in the next release, thus there may be some unmatched contents in the document if you use the newest 1.2-M1 instead of the previous stable version 1.1-Xmas.**
[documents](http://astamuse.github.io/asta4d/1.1-Xmas/)
[Online Sample](http://asta4dsample-xzer.rhcloud.com/)
There is a maven archetype for asta4d. If you want to start with the archetype, you have to [install Maven 3](http://maven.apache.org/download.cgi) at first. After installed Maven 3, create the sample project by the following command:
```batch
mvn archetype:generate \
-DarchetypeGroupId=com.astamuse \
-DarchetypeArtifactId=asta4d-archetype \
-DarchetypeVersion=1.1-Xmas \
-DgroupId=<your.groupid> \
-DartifactId=<your-artifactId>
```
or simply follow the wizard by filtered list:
```batch
mvn archetype:generate -DarchetypeGroupId=com.astamuse -DarchetypeArtifactId=asta4d-archetype -DarchetypeVersion=1.1-Xmas
```
*The 1.1-Xmas with better Java 8 support is recommended for new projects, if you cannot use Java 8, use 1.0-Valentines instead.*
After the archetype is created, enter the folder which has a "pom.xml" file, run the following command:
```batch
mvn jetty:run
```
Then you can access the sample project by http://localhost:8080, there are source samples shown, it is a good start from reading the samples.
After you confirm the sample project is OK, you can add your own url mapping rules to /src/main/java/.../.../UrlRules.java,
and also you can add your own html template files to /src/main/webapp.
Reading the [Best Practice](http://astamuse.github.io/asta4d/1.1-Xmas/userguide/index.html#chapter-best-practice) before writing your own code is recommended.
## What is Asta4D
Asta4D is a view first web application framework which is friendly to designers and flexible to developers. Asta4D affords high productivity than traditional MVC architecture by "View First" architecture. It also allows front-end engineers and back-end engineers work independently without interference by separating rendering logic from template files.
Asta4D is inspired by [lift](http://liftweb.net/) which is a famous scala web application framework and it is developed by astamuse company Ltd. locating at Tokyo Japan. We are concentrating on global innovation support and developing Asta4D for our own services. Currently, Asta4D is driving our new service development.
## Why Asta4D
In the past decade, plenty of Java based web application frameworks are generated. Especially the MVC
architecture and JSP tag libs (or other traditional template technologies) that has greatly released our
productivity. But unfortunately, we are still suffering from the following situations:
1. The designers or front-end engineers are keeping complaining the mixed-in dynamic code, as they disturb their efforts of redesigning the page style or structure. And in the mean time, the back-end developers are also complaining that the front-end guys break the working page frequently, because redesign or the new design is hard to merge due to the huge cost of source refactoring.
1. The developers are complaining about the poor functionalities of template language which they are using and tired from the various magic skills for complex rendering logic.
1. The developers are discontented with the counterproductivity of MVC architecture and desire a more efficient approach.
Thus, we created Asta4D. Currently, Asta4D is driving our service site:[astamuse.com](http://astamuse.com)
## What does "Asta4D" mean
The name of Asta4D is from our company's name: astamuse. We explain the "4D" as following ways:
1. For designers
Asta4D consider the design friendliness as the most important factor of itself. We hope web designers can fulfil their maximum potential of creativity without squandering their time on the back-end technologies which they could never be adept at.
1. For developers
We hope Asta4D can help developers to achieve their work more easily. Developers would never be afflicted with complex rendering logic because they can use powerful Java language to do whatever they want since the rendering has been split from template files. View first also releases developers from the cumbersome MVC architecture, now they have more time to have a cup of coffee.
1. 4 dimension
We believe that Asta4D can act as a wormhole that connects the front-end and the back-end. We can move quicker by Asta4D just like we are going through the 4 dimensional space.
## How Asta4D helps us
Asta4D is our solution to combat those issues. Thanks to lift, from where we learn a lot. We designed Asta4D complying with the following points:
1. Separate template and rendering logic
Asta4D affords front-end engineers a friendly environment by separating rendering logic from template files which are pure html files. At the mean time, back-end engineers can use the powerful Java language to implement the rendering logic without being suffering from the "poor and sometimes magic" template languages.
There is no dynamic code in template file. An Asta4D template file is always a pure HTML file which can be easily maintained by front-end developers, it is very design friendly and we can reduce the workload for source refactoring by over 90%.
```html
<section>
<article>
<div afd:render="SimpleSnippet">dummy text</div>
<afd:snippet render="SimpleSnippet:setProfile">
<p id="name">name:<span>dummy name</span></p>
<p id="age">age:<span>0</span></p>
</afd:snippet>
</article>
</section>
```
In the snippet class, we use traditional CSS selector to reference rendering target, amazing and powerful.
```java
public class SimpleSnippet {
public Renderer render(String name) {
if (StringUtils.isEmpty(name)) {
name = "Asta4D";
}
return Renderer.create("div", name);
}
public Renderer setProfile() {
Renderer render = Renderer.create();
render.add("p#name span", "asta4d");
render.add("p#age span", 20);
return render;
}
}
```
1. Testable Rendering logic
All of the rendering logic of Asta4D is testable and you can simply test them by write simple junit cases, which can replace over than half of selenium tests.
```java
// prepare test target
Renderer render = Renderer.create();
render.add("#someIdForInt", 12345);
// perform test
RendererTester tester = RendererTester.forRenderer(render);
Assert.assertEquals(tester.get("#someIdForInt"), 12345);
```
Rendering for list data can be performed as well
```java
// prepare test target
Renderer render = Renderer.create();
render.add("#someIdForInt", Arrays.asList(123, 456, 789));
// perform test
RendererTester tester = RendererTester.forRenderer(render);
Assert.assertEquals(tester.getAsList("#someIdForInt"), Arrays.asList(123, 456, 789));
```
[Further samples for test](https://github.com/astamuse/asta4d/blob/develop/asta4d-core/src/test/java/com/astamuse/asta4d/test/unit/RenderTesterTest.java)
1. High security of being immune from cross-site(XSS/CSRF)
Asta4D is, by nature, immune from cross-site(XSS/CSRF) problems. You do not need to take care of cross-site any more. All the rendered value would be escaped by default and your clients have no chance to put malicious contents to your server.
1. View first
Asta4D also affords higher productivity than traditional MVC architecture by View First mechanism. And it is also easier to change than MVC architecture.
A controller is not necessary for request dispatch. All the requests cound be dispatched by a sort of predefined URL matching rules and could be forwarded to template files directly, which is called as view first.
```java
rules.add("/app/", "/templates/index.html");
```
1. Isolate side effect with request handler
Asta4D imports the conception of "side-effect" from functional programming languages and separating the "side-effect" by request handlers, which afford more flexibility on page rendering because the view layer is side-effect free now. Therefore Asta4D allows parallel page rendering in multiple threads as a built-in feature.
[See details about side effect](http://astamuse.github.io/asta4d/userguide/#chapter-side-effect)
1. Advanced MVC
Asta4D also affords a evolved MVC architecture which is more clarified for the duty of each application layer than the traditional MVC architecture.
By traditional MVC architecture, we often have to expand the transaction from the controller layer across to the view layer to combat the lazy load issue, which ugly structure is essentially caused by the tangled controller which holds various unrelated duties.
It is also strange that we have to modify our controller's implementation at every time we change the page appearance at view layer. Such situation could not satisfy us since the layers are not uncoupled really.
We would say that the traditional controller is indeed a tangled magic container for most logics, a controller will unfortunately be coupled to most layers in the system even our initial purpose of MVC is to uncouple our logics. By contrast, Asta4D allows developers to really uncouple all the tangled logics easily. Basically we could split the traditional controller's duty to following parts:
- request handler
Which takes the responsibilities of all the operations with side-effect.
- result matching in url rule
Which dispatches the request to different views according to the result from request handler
- snippet class
Which has the responsibility to render data to the page and also holds the obligation of preparing all the necessary data for page rendering.
By above architecture, we could perfectly uncouple our logics by clarifying the obligation of each layer.
1. Built-in form flow mechanism
Asta4D treat all the form processes as flow and afford a well defined architecture for various form processes. Asta4D gives developers the possibility of concentrating on their real business logics rather than technic issues. Basically, developers only need to implement an init method and an update method for a form process.
```java
public class SingleInputFormHandler extends OneStepFormHandler<PersonForm> {
@Override
protected PersonForm createInitForm() throws Exception {
...
}
@Override
protected void updateForm(PersonForm form) {
...
}
}
```
