Diagram
Diagram is a small CLI application to generate hand drawn diagrams from ASCII art.
Installation
In order to run the application please make sure that Go is installed on your local machine and check if $GOPATH/bin
is included into the PATH
directory.
Run the following commands to download the project and build the executable.
$ git clone https://github.com/esimov/diagram
$ cd diagram
$ go build
# Start the application
$ diagram
Build
A shell script is bundled into the library to mitigate the generation of binary files for the most known operating systems, but take care: different dependencies are needed for different operating systems. To build the executable file run:
$ make all
Usage
Once you are inside the terminal application you can create, edit or delete the ASCII diagrams. By pressing CTRL+d
you can convert the ASCII art into a handwritten diagram. The generated PNG
file will be saved into the output
folder relative to the current path.
Command Line support
The application also supports the generation of hand drawn diagrams directly from command line without to enter into the CLI application.
$ diagram --help
will show the currently supported options:
