Commands
marmot size
Size of a binary by section, package and function.
greet
Break an executable down by section, by package and by function, and show what calls a function (-why). Function names and sizes come from marmot's pc table, or from the symbol table for other binaries.
marmot size BINARY [flags]Examples
marmot size ./app
marmot size -pkg fmt ./app
marmot size -why fmt.Sprintf ./appmarmot size app lists the sections of the executable, the code of each package and the
largest functions. -pkg fmt lists one package's functions; -why fmt.Sprintf prints a chain
of direct calls from main to the function, which says why it is linked in. It also reads
binaries built by other compilers, through their symbol table.
-json writes one size object with sections, packages and functions; with -why it
has why with chain.
Flags
Flags take one dash or two: -release and --release are the same.
| Flag | Meaning |
|---|---|
-color string | color in human output: auto, always or never (NO_COLOR turns auto off) (default "auto") |
-json | machine readable output: JSON Lines on stderr (also $MARMOT_OUTPUT=json, and the default under coding agents) |
-n string | how many packages and functions to list (default "15") |
-pkg string | list the functions of this package only |
-why string | show a chain of direct calls from main to this function |
