|-
| 00:01
| Welcome to the spoken tutorial on creating '''new environments '''in '''LaTeX'''.

|-
| 00:08
| This tutorial will help the learners to

create or define new '''environments''' to get customized output.

|-
| 00:15
| redefine the existing '''environments'''.

|-
| 00:18
| To follow this tutorial,

You should have knowledge of '''commands '''that are necessary to create a document in '''LaTeX'''.

|-
| 00:24
| You should also have knowledge of '''compiling '''and producing a '''PDF output '''in '''LaTeX'''.

|-
| 00:30
| If not, please go through the relevant '''LaTeX''' spoken tutorials on this website.

|-
| 00:37
| To record this tutorial, I am using

'''Ubuntu Linux 14.04''' operating system, '''TeXWorks 0.5'''

|-
| 00:47
| Just like '''new commands,''' we can define '''new environments.'''

|-
| 00:51
| As the name suggests the command '''newenvironment''' is used to create/define a new '''environment'''.

|-
| 00:58
| It is used to format blocks of text, generally.

|-
| 01:04
| '''New environment''' is a variation of executing few existing commands put together in a sequence.

|-
| 01:10
| Ensure that the custom '''environment''' you create, is not an already existing '''LaTeX environment'''.

|-
| 01:18
| The syntax to define a new '''environment '''is ''' backslash newenvironment environment name within curly braces start commands within curly braces end commands within curly braces '''

|-
| 01:32
| Here the '''start commands''' are executed whenever the environment starts.

|-
| 01:37
| And '''end commands''' are executed whenever the environment ends.

|-
| 01:42
| Let us open the '''TeXWorks''' editor.

|-
| 01:48
| Pause the tutorial at this point.

|-
| 01:50
| Download and unzip the files provided in the '''Code Files''' link below the player.

|-
| 01:57
| You will see some '''LaTeX code''' given in the file '''newEnv.tex'''

|-
| 02:06
| We will copy and paste the first block of code from this file into our newly opened '''tex''' file.

|-
| 02:27
| Let’s try to understand the program.

|-
| 02:30
| Here '''\newenvironment{bluetext}''' means that we are defining a new '''environment''' called '''bluetext.'''

|-
| 02:39
| Here in the definition we center the text and colour it with blue using

'''{\begin{center}\color{blue}}'''

'''{\end{center}}'''

|-
| 02:51
| While using it, we just give '''\begin{bluetext}''' and''' \end{bluetext}''' with the intended text between the two.

|-
| 03:04
| Save the file as '''newEnv.tex'''

|-
| 03:15
| Let us compile and see the output.

|-
| 03:19
|Observe the blue text in the output.

|-
| 03:29
| Now, we will see how to use '''parameters''' in the '''environments'''.

|-
| 03:36
| '''New environment''' with parameter is defined as

backslash newenvironment environment name within curly braces parameters in square bracket start commands within curly braces end commands within curly braces.

|-
| 03:56
| Let’s open a new file in '''TeXWorks'''.

|-
| 04:03
| Now switch to our downloaded code file.

|-
| 04:16
| We will copy the next block of code from our downloaded code file

|-
| 04:26
|and paste it into our new '''teX''' file.

|-
| 04:32
| Let us understand the code now.

|-
| 04:34
| Here in the given code, we are adding a title to the blue text by getting the title as an '''input parameter.'''

|-
| 04:45
| We have just added textbf textit hash 1 slash slash 12pt to the code given for the '''environment''' without '''parameter'''

|-
| 05:01
| We use it as '''“ begin bluetext My text in blue ”''' and the text,

and then '''“\end{bluetext}”'''

|-
| 05:18
| Save the file as '''newEnvp1.tex'''

|-
| 05:31
| Now compile and see the output.

|-
| 05:44
| We shall see the '''renewenvironment''' now.

|-
| 05:51
| '''renewenvironment '''is used to change or overwrite the existing environment.

|-
| 05:56
| The syntax for '''renewenvironment''' is

''' backslash renewenvironment environment name within curly braces start commands within curly braces end commands within curly braces '''

|-
| 06:12
| It’s quite similar to '''newenvironment'''.

|-
| 06:16
| Once again, we will open a new '''tex''' file.

|-
| 06:28
| We will copy and paste the last block of code from our downloaded file

|-
| 06:48
| into our newly opened '''tex''' file.

|-
| 06:53
| Let us understand the code.

|-
| 06:59
| ''' renewenvironment itemize '''redefines the '''itemize environment.'''

|-
| 07:06
| It is defined as ''' begin center large ''' '''end center '''

|-
| 07:12
| This means that the text should be centered and made to '''large''' size.

|-
| 07:18
| Recall that the '''itemize environment '''creates a list according to the original definition.

|-
| 07:24
| Let’s see the usage.

|-
| 07:27
| The text given within '''\begin{itemize}''' and''' \end{itemize}''' should be converted to large size and centered according to our definition

|-
| 07:42
| Let us save the file as '''renewEnv.tex '''and compile the '''tex''' file.

|-
| 07:59
| Observe the output.

|-
| 08:08
| To summarise, we have learnt

'''newenvironment''', '''newenvironment''' with '''parameters''', '''renewenvironment'''

|-
| 08:21
| Create an environment '''itemizecolor, ''' which takes the color (red, blue, yellow, green) as input

and creates a list in that color.

|-
| 08:38
| The video at the following link summarises the Spoken Tutorial project.

Please watch it.

|-
| 08:46
| The Spoken Tutorial Project Team :

Conducts workshops using spoken tutorials and Gives certificates to those who pass an online test
