# trdot
Reads a tree from stdin and prints the tree as a Dot graph.
# Usage
trdot
# Details
`trdot` reads parse tree data via stdin and outputs
a Dot graph specification. The stdout can be redirected to
save the output to a file. Or, you can copy the output and
use an online Dot graph visualizer to make a plot.
Any parse tree data can be converted to Dot, include a
parse of a grammar, the parse tree of a simple expression grammar,
or a list of parse tree nodes obtained via
[trxgrep](https://github.com/kaby76/Domemtech.Trash/tree/main/trxgrep).
# Examples
Consider the Expression grammar, obtained via
mkdir foo; cd foo; trgen; cd Generated; dotnet build
Let's parse the expression "1+2" and print the parse tree as a Dot graph:
trparse -i "1+2" | trdot
The output will be:
digraph G {
Node18643596 [label="file_"];
Node33574638 [label="expression"];
Node33736294 [label="expression"];
Node35191196 [label="atom"];
Node48285313 [label="scientific"];
Node31914638 [label="1"];
Node18796293 [label="+"];
Node34948909 [label="expression"];
Node46104728 [label="atom"];
Node12289376 [label="scientific"];
Node43495525 [label="2"];
Node55915408 [label="EOF"];
