|
|
This tool converts any file into managable Go source code. Useful for embedding
|
2012-06-13 12:17:25 +00:00
|
|
|
binary data into a go program. The file data is optionally gzip compressed
|
|
|
|
before being converted to a raw byte slice.

### Usage

|
|
The simplest invocation is to pass it only the input file name.
|
|
|
|
The output file and code settings are inferred from this automatically.

|
|
$ go-bindata -i testdata/gophercolor.png
|
2011-06-17 15:44:59 +00:00
|
|
|
[w] No output file specified. Using 'testdata/gophercolor.png.go'.
|
|
|
|
[w] No package name specified. Using 'main'.
|
|
|
|
[w] No function name specified. Using 'gophercolor_png'.
|
|
|
|
[i] Done.
|
|
|
|
|

|
|
|
This creates the `testdata/gophercolor.png.go` file which has a package
|
|
|
|
declaration with name `main` a variable holding the file data in a read-only
|
|
|
|
string and one function named `gophercolor_png` with the following signature:
|
2011-06-17 15:44:59 +00:00
|
|
|
|
2012-06-13 12:17:25 +00:00
|
|
|
func gophercolor_png() []byte
|
2012-03-08 10:47:57 +00:00
|
|
|
|
2012-06-13 12:17:25 +00:00
|
|
|
You can now simply include the new .go file in your program and call
|
|
|
|
`gophercolor_png()` to get the uncompressed image data. The function panics
|
|
|
|
if something went wrong during decompression. See the testdata directory for
|
|
|
|
example input and output.
|

|
|
|
|
|
|
|
Aternatively, you can pipe the input file data into stdin. bindata will then
|
|
|
|
spit out the generated Go code to stdout. This does require explicitly naming
|
|
|
|
the desired function name, as it can not be inferred from the input data.
|
|
|
|
The package name will still default to 'main'.

Invoke the program with the -h flag for more options.

### Optional compression
|
|
|
|
|
|
|
|
When the `-u` flag is given, the supplied resource is *not* GZIP compressed
|
2012-06-13 12:17:25 +00:00
|
|
|
before being turned into Go code. The data should still be accessed through
|
|
|
|
a function call, so nothing changes in the usage of the generated file.
|
|
|
|
|
|
|
|
This feature is useful if you do not care for compression, or the supplied
|
|
|
|
resource is already compressed. Doing it again would not add any value and may
|
|
|
|
even increase the size of the data.
|
2012-03-27 23:39:01 +00:00
|
|
|
|
|
|
|
The default behaviour of the program is to use compression.
