#+TITLE: callgraph

This repository currently provides 1 command =callgraph= (=./cmd/callgraph=) to analyze Go codes with call graphs.

  • Command: =callgraph=

The command =callgraph= (=./cmd/callgraph=) provides some subcommands.

** Subcommand: =draw=

Example command:

#+BEGIN_SRC bash $ callgraph draw unicode #+END_SRC

Output:

#+BEGIN_SRC dot strict digraph G { 8 [label="(unicode.SpecialCase).ToTitle"] 11 [label="unicode.ToUpper"] 12 [label="unicode.To"] 16 [label="unicode.IsNumber"] 25 [label="unicode.init"] 2 [label="(unicode.SpecialCase).ToUpper"] 3 [label="unicode.is16"] 5 [label="unicode.isExcludingLatin"] 31 [label="unicode.IsGraphic"] 22 [label="unicode.IsOneOf"] 32 [label="unicode.IsLetter"] 13 [label="unicode.IsSpace"] 17 [label="(unicode.SpecialCase).ToLower"] 21 [label="unicode.IsUpper"] 23 [label="unicode.IsDigit"] 24 [label="unicode.IsSymbol"] 26 [label="unicode.IsPunct"] 6 [label="unicode.IsPrint"] 10 [label="unicode.ToTitle"] 15 [label="unicode.is32"] 28 [label="unicode.IsControl"] 29 [label="unicode.IsMark"] 1 [label="(*unicode.SpecialCase).ToUpper"] 4 [label="unicode.IsTitle"] 27 [label="unicode.IsLower"] 18 [label="unicode.ToLower"] 19 [label="(*unicode.SpecialCase).ToTitle"] 20 [label="unicode.SimpleFold"] 30 [label="(*unicode.SpecialCase).ToLower"] 7 [label="unicode.In"] 9 [label="unicode.to"] 14 [label="unicode.Is"] 17 -> 9 12 -> 9 18 -> 12 17 -> 18 30 -> 17 14 -> 3 14 -> 15 7 -> 14 8 -> 9 10 -> 12 8 -> 10 19 -> 8 20 -> 18 11 -> 12 20 -> 11 5 -> 3 5 -> 15 16 -> 5 2 -> 9 2 -> 11 31 -> 7 13 -> 5 21 -> 5 22 -> 14 32 -> 5 23 -> 5 6 -> 7 24 -> 5 26 -> 14 1 -> 2 4 -> 5 27 -> 5 29 -> 5 } #+END_SRC

The above =dot= graph would generate the following png:

[[file:./assets/draw_unicode.png]]

** Subcommand: =statistics=

Example command:

#+BEGIN_SRC bash $ callgraph statistics unicode #+END_SRC

Output:

#+BEGIN_SRC text
