Display tty

Take a look

This project now has automated documentation that gets generated, this manually written one will remain for legacy reasons, but you can now take a look at the automatic documentation here: https://hanra-s-work.github.io/display_tty/

Description

This is a python package I created in order to simplify the boiling process for displaying text in a geometrical shape drawn using characters.

Disclaimer

The package was originally named disp but had to be changed to display_tty because the names disp and display were already taken by other packages.

The class will still remain Disp but bindings named Display, DispTTY and DisplayTTY are available.

The Preloaded version exists under: IDISP, IDISPLAY, IDTTY and IDISPTTY

Installation

Using pip

pip install -U display-tty

Using python

Under Windows:

py -m pip install -U display-tty

Under Linux/Mac OS:

python3 -m pip install -U display-tty

Usage

Importing

from display_tty import IDTTY

Initialising

The generic class is: Disp(toml_content: dict, save_to_file: bool = False, file_name: str = "text_output_run.txt", file_descriptor: any = None)

For your convenience, you can use the IDTTY variable which is an initialised version of the class.

IDTTY.title("Hello World")

Otherwise, if you wish to initialise the class with your own parameters, you can do so like this:

from display_tty import DisplayTTY
TOML_CONF = {
    'PRETTIFY_OUTPUT': True,
    'PRETTY_OUTPUT_IN_BLOCS': True,
    'MESSAGE_CHARACTER': '@',
    'MESSAGE_ERROR_CHARACTER': '#',
    'MESSAGE_INFORM_CHARACTER': 'i',
    'MESSAGE_QUESTION_CHARACTER': '?',
    'MESSAGE_SUCCESS_CHARACTER': '/',
    'MESSAGE_WARNING_CHARACTER': '!',
    'SUB_SUB_TITLE_WALL_CHARACTER': '*',
    'SUB_TITLE_WALL_CHARACTER': '@',
    'TITLE_WALL_CHARACTER': '#',
    'TREE_COLUMN_SEPERATOR_CHAR': '│',
    'TREE_LINE_SEPERATOR_CHAR': '─',
    'TREE_NODE_CHAR': '├',
    'TREE_NODE_END_CHAR': '└',
    'MESSAGE_ANIMATION_DELAY_BLOCKY': 0.01,
    'MESSAGE_ANIMATION_DELAY': 0.01
}
 
SAVE_TO_FILE = False
FILE_NAME = "run_results.txt"
FILE_DESCRIPTOR = None
 
 
IDTTY = DisplayTTY(
    TOML_CONF,
    SAVE_TO_FILE,
    FILE_NAME,
)

Calling the tree function

The generic function is:

tree(self, title: str, data: list[str], offset: int = 0)

The output is: None

TEST_DATA = {
    "test_data1": "test_data1.1",
    "test_data2": "test_data2.1",
    "test_data3": [
        "test_data_list3.1",
        "test_data_list3.2",
        "test_data_list3.3",
        "test_data_list3.4",
        "test_data_list3.5"
    ],
    "test_data4": "test_data4.1",
    "test_data5": {
        "test_data5.1": "test_data5.1.1",
        "test_data5.2": "test_data5.2.1",
        "test_data5.3": "test_data5.3.1",
        "test_data5.4": "test_data5.4.1"
    },
    "test_data6": [
        {
            "test_data6.1": "test_data6.1.1",
            "test_data6.2": "test_data6.2.1"
        },
        [
            "test_data_list6.3.1",
            "test_data_list6.3.1",
            "test_data_list6.3.1",
            "test_data_list6.3.1"
        ]
    ],
    "test_data7": {
        "test_data7.1": {
            "test_data7.1.1": "test_data7.1.1.1",
            "test_data7.1.2": "test_data7.1.2.1"
        },
        "test_data7.2": [
            "test_data7.2.1",
            "test_data7.2.2",
            "test_data7.2.3",
            "test_data7.2.4",
            "test_data7.2.5"
        ]
    }
}
 
IDTTY.tree("This is a test tree", TEST_DATA, 0)

Change the initialisation content

When initialising the class it is possible to change the animation behaviour by editing the TOML_CONF that you must provide when initialising the class.

During the initialisation it is also possible to redirect the output to a file instead of displaying it on the terminal. For this, please set the save_to_file to True and either:

• provide a file name in file_name
• provide a file descriptor in file_descriptor

If you provided a file_name, the file will automatically be opened However, in both cases, you will need to close the file by calling the function close_file (i.e. at the end of your program)

TOML configuration breakdown

This is the arguments that are required in the TOML file:

 #toml
1  | PRETTIFY_OUTPUT: True,
2  | PRETTY_OUTPUT_IN_BLOCS: True,
3  | MESSAGE_CHARACTER: '@',
4  | MESSAGE_ERROR_CHARACTER: '#',
5  | MESSAGE_INFORM_CHARACTER: '!',
6  | MESSAGE_QUESTION_CHARACTER: '?',
7  | MESSAGE_SUCCESS_CHARACTER: '/',
8  | MESSAGE_WARNING_CHARACTER: '?',
9  | SUB_SUB_TITLE_WALL_CHARACTER: '*',
10 | SUB_TITLE_WALL_CHARACTER: '@',
11 | TITLE_WALL_CHARACTER: '#',
12 | TREE_COLUMN_SEPERATOR_CHAR: '│',
13 | TREE_LINE_SEPERATOR_CHAR: '─',
14 | TREE_NODE_CHAR: '├',
15 | TREE_NODE_END_CHAR: '└',
16 | MESSAGE_ANIMATION_DELAY_BLOCKY: 0.01,
17 | MESSAGE_ANIMATION_DELAY: 0.01

PS: I've added line numbers <number> | to help you track the analysis of the file, these are generally added automatically by your code editor.

Thats a big file, lets break it down together:

line 1

 #toml
PRETTIFY_OUTPUT: True

This option is a crucial pivot for the program.

If:

• True: The program will output the content letter by letter while waiting a specified delay
• False: It will print out all of your messages at once without waiting any delay

line 2

 #toml
PRETTY_OUTPUT_IN_BLOCS: True

This option is an optimisation for the program.

If:

• True: The program will:
  • Extract the words from the input
  • output the content word by word while waiting a specified delay and respecting spacing
• False: It will print out all of your messages at once without waiting any delay

line 3

 #toml
MESSAGE_CHARACTER: '@'

This is a customisation, it allows you to specify the characther to use when displaying a message.

line 4

 #toml
MESSAGE_ERROR_CHARACTER: '#'

This is a customisation, it allows you to specify the characther to use when displaying an error message.

line 5

 #toml
MESSAGE_INFORM_CHARACTER: '!'

This is a customisation, it allows you to specify the characther to use when displaying an inform message.

line 6

 #toml
MESSAGE_QUESTION_CHARACTER: '?'

This is a customisation, it allows you to specify the characther to use when displaying a question message.

line 7

 #toml
MESSAGE_SUCCESS_CHARACTER: '/'

This is a customisation, it allows you to specify the characther to use when displaying a success message.

line 8

 #toml
MESSAGE_WARNING_CHARACTER: '?'

This is a customisation, it allows you to specify the characther to use when displaying a warning message.

line 9

 #toml
SUB_SUB_TITLE_WALL_CHARACTER: '*'

This is a customisation, it allows you to specify the characther to use when displaying a sub sub title.

line 10

 #toml
SUB_TITLE_WALL_CHARACTER: '@'

This is a customisation, it allows you to specify the characther to use when displaying a sub title.

line 11

 #toml
TITLE_WALL_CHARACTER: '#'

This is a customisation, it allows you to specify the characther to use when displaying a title.

line 12

 #toml
TREE_COLUMN_SEPERATOR_CHAR: '│'

This is the character used by the tree function to indicate the indentation level

i.e:

│   ├─── my_file

line 13

 #toml
TREE_LINE_SEPERATOR_CHAR: '─'

This is the character used by the tree function to indicate the file/folder of the current line

i.e:

├─── my_file

line 14

 #toml
TREE_NODE_CHAR: '├'

This is the character used by the tree function to indicate the directory level to wich the file/directory is linked but that this is not the last file/directory.

i.e:

├─── my_file

line 15

 #toml
TREE_NODE_END_CHAR: '└'

This is the character used by the tree function to indicate the directory level to wich the file/directory is linked but that this is the last file/directory.

i.e:

└─── my_file

line 16

 #toml
MESSAGE_ANIMATION_DELAY_BLOCKY: 0.01

Specify the delay between each word placement. (min: 0)

PS: if you enter 0, this is like setting PRETTY_OUTPUT_IN_BLOCS to False

line 17

 #toml
MESSAGE_ANIMATION_DELAY: 0.01

This variable is a pivot point for the program.

Specify the delay between each word placement. (min: 0)

PS: if you enter 0, this is like setting PRETTY_OUTPUT_IN_BLOCS to False

Update the configuration of an initialised class

If the default initialisation, or the class you previously initialised has some elements you would like to update, you can do so by calling the inner variables.

Here are the variables you might be interested in:

from display_tty import IDTTY
IDTTY.title_wall_chr # string (length 1): i.e.: '#'
IDTTY.sub_title_wall_chr # string (length 1): i.e.: '@'
IDTTY.sub_sub_title_wall_chr # string (length 1): i.e.: '*'
IDTTY.message_char # string (length 1): i.e.: '@'
IDTTY.message_error_char # string (length 1): i.e.: '#'
IDTTY.message_success_char # string (length 1): i.e.: '/'
IDTTY.message_inform_char # string (length 1): i.e.: 'i'
IDTTY.message_warning_char # string (length 1): i.e.: '!'
IDTTY.message_question_char # string (length 1): i.e.: '?'
IDTTY.message_animation_delay # float: i.e.: # 0.01
IDTTY.tree_node_char # string (length 1): i.e.: '├'
IDTTY.tree_node_end_char # string (length 1): i.e.: '└'
IDTTY.tree_line_seperator_char # string (length 1): i.e.: '─'
IDTTY.tree_column_seperator_char # string (length 1): i.e.: '│'
IDTTY.save_to_file # True or False
IDTTY.toml_content["PRETTIFY_OUTPUT"] # True of False
IDTTY.toml_content["PRETTY_OUTPUT_IN_BLOCS"] # True of False

To update a variable, simply assing it a new value, like in this example: IDTTY.title_wall_chr = "&"

PS: These changes only apply to the class you loaded, any others will not be touched.
