## OVERVIEW

Durdraw is an ASCII, Unicode and ANSI art editor for UNIX-like systems (Linux,
macOS, etc). It runs in modern Utf-8 terminals and supports frame-based
animation, custom themes, 256 and 16 color modes, terminal mouse input, DOS
ANSI art viewing, CP437 and Unicode mixing and conversion, HTML output, mIRC
color output, and other interesting features.

Durdraw is heavily inspired by classic ANSI editing software for MS-DOS and
Windows, such as TheDraw, Aciddraw and Pablodraw, but with a modern Unix twist.

## REQUIREMENTS

* Python 3 (3.10+ recommended)
* Linux, macOS, or other Unix-like System

## INSTALLATION

You can install from your OS repositories, or follow the instructions below to install from source:

[![Packaging status](https://repology.org/badge/vertical-allrepos/durdraw.svg)](https://repology.org/project/durdraw/versions)

If you just want to run it without instalilng, scroll down to the next section.

1: Download and extract, or use git to download:

```
   git clone https://github.com/cmang/durdraw.git  
   cd durdraw 
```

2: Install or upgrade using pip:

```
    pip install --upgrade .
```

Or run the installer:

```
    python3 setup.py install
```

3: Optionally, install some themes and a sample configuration file for your local user into ~/.durdraw/:

```
    ./installconf.sh
```


You should now be able to run `durdraw`. Press `esc-h` for help, or try `durdraw --help` for command-line options.

## RUNNING WITHOUT INSTALLING

You can run Durdraw with:

```
    ./start-durdraw
```

To look at some included example animations:

```
    ./start-durdraw -p examples/*.dur
```

## OPTIONAL INSTALLATION

For PNG and animated GIF export, please install Ansilove (https://ansilove.org/) and make sure it is is in your path. PNG and GIF export only work in 16-color mode for now, and only with CP437 compatible charcters. You also need the PIL python module.

For Durfetch support, please install Neofetch and place it in your path.

 ANIMATION:

    Use the Animation Menu [Anim] or keyboard commands to insert (esc-n),
    delete (esc-d), move (esc-M) and edit frames. Use esc-k and esc-j to
    flip to the next and previous frames. The "Play" button (|> or esc-p)
    starts or stops playback.

    When the animation is playing, all changes made effect all frames
    within the current playback/edit Range (R: or esc-R). Change playback
    speed (<FPS> or Frames Per Second) with esc-+ (or esc-=) and esc--.
    F: shows the current frame number, and you can go to a specific frame
    with esc-g.

 BRUSHES:

    To make a brush, use shift-arrow or esc-K to make a selection, then
    press b. To use the brush, click the Mouse Tools menu (esc-t) and select
    Paint (P). You can now use the mouse to paint with your custom brush.
```

## CONFIGURATION

You can create a custom startup file where you can set a theme and other options.

If you did not already do so during installation, you can install a sample configuration and some themes into ~/.durdraw/ with the command:

```
    ./installconf.sh
```

This will place durdraw.ini into ~/.durdraw/ and the themes into ~/.durdraw/themes/.

Here is an example durdraw.ini file, showing the available options:

<pre>
; Durdraw 0.28.0 Configuration File

[Main]

; color-mode sets the color mode to start in. Available options: 16, 256
;color-mode: 16

; disable-mouse disablse the mouse.
;disable-mouse: True

; max-canvas atuomatically sets the canvas size to the terminal window size at startup.
;max-canvas: True

; Cursor mode requests a cursor type from the terminal. Available options: block, underscore, pipe
;cursor-mode: underscore

; When scroll-colors is enabled, using the mouse wheel in the canvas changes the
; foreground color instead of moving the cursor.
;scroll-colors: True

[Theme]
theme-16: ~/.durdraw/themes/mutedchill-16.dtheme.ini
theme-256: ~/.durdraw/themes/mutedform-256.dtheme.ini
</pre>

The option 'theme-16' sets the path to the theme file used in 16-color mode, and 'theme-256' sets the theme file used for 256-color mode. 

You can also load a custom theme file using the --theme command-line argument and passing it the path to a theme file, or disable themes entirely with the --notheme command line option.

Here is an example 16-color theme:

<pre>
[Theme-16]
name: 'Purple Drank'
mainColor: 6
clickColor: 3
borderColor: 6
clickHighlightColor: 5
notificationColor: 4
promptColor: 4
</pre>

and a 256-color theme:

<pre>
[Theme-256]
name: 'Muted Form'
mainColor: 104
clickColor: 37
borderColor: 236
clickHighlightColor: 15
notificationColor: 87
promptColor: 189
menuItemColor: 189
menuTitleColor: 159
menuBorderColor: 24
</pre>

The colors and theme options are as follows:

colors for 16-color mode:
1 black
2 blue
3 green
4 cyan
5 red
6 magenta
7 yellow
8 white

color codes numbers for 256-color mode can be found in Durdraw's 256-color selector.

```
mainColor: the color of most text
clickColor: the color of buttons (clickable items)
clickHighlightColor: the color the button changes to for a moment when clicked
borderColor: the color of the border around a drawing
notificationColor: the color of notification messages
promptColor: the color of user prompt messages
menuItemColor: the color of menu items
menuTitleColor: the color of menu titles
menuBorderColor: the color of the border around menus
```

## DURFETCH

Durfetch is a program which acts like a fetcher. It uses Neofetch to obtain system statistics and requires that Neofetch be found in the path. You can put keys in your .DUR files which durfetch will replace with values from Neofetch. You can also use built-in example animations.

Note that this feature is in beta, and is far from perfect, but it can be fun to play with. If anyone wants to improve durfetch, please feel free.

Keys will only be replaced if there is enough room in the art for the replacement value.

The following values can be used in your art and automatically interpreted by Durfetch:

```
{OS}
{Host}
{Kernel}
{Uptime}
{Packages}
{Shell}
{Resolution}
{DE}
{WM}
{WM Theme}
{Terminal}
{Terminal Font}
{CPU}
{GPU}
{Memory}
```

The durfetch executable takes the following command-line paramaters:

```
usage: durfetch [-h] [-r | -l LOAD] [--linux | --bsd] [filename ...]

An animated fetcher. A front-end for Durdraw and Neofetch integration.

positional arguments:
  filename              .durf ASCII and ANSI art file or files to use

options:
  -h, --help            show this help message and exit
  -r, --rand            Pick a random animation to play
  -l LOAD, --load LOAD  Load an internal animation
  --linux               Show a Linux animation
  --bsd                 Show a BSD animation

Available animations for -l:

bsd
cm-eye
linux-fire
linux-tux
unixbox
```

Here are some durfetch examples:

## FAQ

#### Q: Durdraw crashed! What do I do?
A: Oh no! I am sorry and hope nothing important was lost. But you can help fix it. Please take a screenshot of the crash and post it as a bug report at https://github.com/cmang/durdraw/issues/. Please try to describe what you were trying to do when it happened, and if possible, include the name of your terminal, OS and Python version. I will do my best to try to fix it ASAP. Your terminal will probably start acting weird if Durdraw crashed. You can usually fix it by typing "reset" and pressing enter.

#### Q: Don't TheDraw and some other programs already do ANSI animation?
A: Yes, but traditional ANSI animation does not provide any control over timing, instead relying on terminal baud rate to govern the playback speed. This does not work well on modern systems without baud rate emulation. Durdraw gives the artist fine control over frame rate, and delays per frame. Traditional ANSI animation also updates the animation one character at a time, while Durdraw updates the animation a full frame at a time. This makes it less vulnerable to visual corruption from things like errant terminal characters, resized windows, line noise, etc. Finally, unlike TheDraw, which requires MS-DOS, Durdraw runs in modern Unicode terminals.

#### Q: Can I run Durdraw in Windows?
A: Short answer: It's not supported, but it seems to work fine in the Windows Subsystem for Linux (WSL), and in Docker using the provided Dockerfile. Long answer: Some versions run fine in Windows Command Prompt, Windows Terminal, etc, without WSL, but it's not tested or supported. If you want to help make Durdraw work better in Windows, please help by testing, submitting bug reports and submitting patches.

#### Q: Can I run Durdraw on Amiga, MS-DOS, Classic MacOS, iOS, Android, Atari ST, etc?
A: Probably not easily. Durdraw requires Python 3 and Ncurses. If your platform can support these, it will probably run. However, the file format for Durdraw movies is a plain text JSON format. It should be possible to support this format in different operating systems and in different applications. See durformat.md for more details on the .dur file format.

#### Q: Does Durdraw support IBM-PC ANSI art?
A: Yes! IBM-PC ANSI art popular in the "ANSI Art Scene" uses Code Page 437 character encoding, which usually needs to be translated to work with modern terminals. When Durdraw encounters these files, it will convert them to Unicode and carry on. When you save ANSI files, it will ask if you want to use CP437 or Utf-8 encoding.

#### Q: I only see 8 colors in 16 color mode. Why?
A: Look in your terminal setting for "Use bright colors for bold," or a similarly named option. Durdraw's 16-color mode, like many vintage terminals (including MS-DOS), uses the Bold escape codes to tell the terminal that colors are "bright." This provides compatibility with many older systems. However, some terminals do not support or enable this option by default. Additionally, your terminal decides what colors to assign to the lower 16 colors. In many terminals, Durdraw can override the default 16 color palette. To do this, click on Menu -> Settings and select VGA, Commodore 64 or ZX Spectrum colors.

#### Q: Some or all of the F1-F10 keys do not work for me! What can I do?
A: You can use ESC-1 through ESC-0 as a replacement for F1-F10. Some terminals will map this to Alt-1 through Alt-0. You can also use the following settings in some terminals to enable the F1-F10 keys:

- **GNOME Terminal**: **Click**: Menu -> Edit -> Preferences -> General, and **uncheck** the box: 

  - [ ] Enable the menu accelerator key (F10 by default)

- **Xfce4-Terminal**: **Click**: Menu -> Edit -> Preferences -> Advanced, and **check** the 2 boxes:

  - [x] Disable menu shortcut key (F10 by default)
  - [x] Disable help window shortcut key (F1 by default)
