# codecgen tool
|
||
|
|
|
||
|
|
Generate is given a list of *.go files to parse, and an output file (fout),
|
||
|
|
codecgen will create an output file __file.go__ which
|
||
|
|
contains `codec.Selfer` implementations for the named types found
|
||
|
|
in the files parsed.
|
||
|
|
|
||
|
|
Using codecgen is very straightforward.

||

||
|
|
|
||
|
|
**Run the tool on your files**
|
||
|
|
|
||
|
|
The command line format is:
|
||
|
|
|
||
|
|
`codecgen [options] (-o outfile) (infile ...)`
|
||
|
|
|
||
|
