ASCII Painter

Inspired by asciiflow.com, this tool converts callgraph text into ascii text-based UML sequence diagram.

Check out todo for implementation progress and plan.

Example

ClassA::func_1
  ClassB::func_2
    ClassB::func_3
    ClassB::func_4
  ClassB::func_2

ClassC
  ClassB::func_3

to UML sequence:

    ┌──────┐    ┌──────┐    ┌──────┐
    │ClassA│    │ClassB│    │ClassC│
    └──────┘    └──────┘    └──────┘
 func  │           │           │
 _1    │           │           │
──────►│           │           │
       │           │           │
       │ func_2    │           │
       │──────────►│           │
       │           │           │
       │           │────┐      │

Syntax

CallGraph: Statements?

Statements: ComponentIdentifier::function_identifier

with spaces in front of each statement indicating the calling stack depth;

with empty line separating callgraph sections to switch calling component, which
is automatically derived within each section.

ComponentIdentifier: string type without space, perferred in CamelCase

function_identifier: string type without space, preferred in snake_case

Usage

cat ./painter/test/callgraph.txt | cargo run
cargo build --release
cat ./painter/test/callgraph.txt | ./target/release/ascii_painter

# install (from repo dir)
cargo install --path ./ascii_painter

Demo

After installing ascii_painter, callgraph text in vim can be turned to graph as demonstrated below:
