### A portable (OSX/Linux/Windows), simple zip library written in C
|
||||
This is done by hacking awesome [miniz](https://code.google.com/p/miniz) library and layering functions on top of the miniz v1.15 API.

|
||||
### Go (cgo)
|
||||
```go
|
||||
package main

|
||||
### Ruby (ffi)
|
||||
Install _ffi_ gem.
|
||||
```shell
|
||||
$ gem install ffi
|
||||
```
|
||||
|
||||
Bind in your module.
|
||||
```ruby
|
||||
require 'ffi'
|
||||
|
||||
module Zip
|
||||
extend FFI::Library
|
||||
ffi_lib "./libzip.#{::FFI::Platform::LIBSUFFIX}"
|
||||
|
||||
attach_function :zip_open, [:string, :int, :char], :pointer
|
||||
attach_function :zip_close, [:pointer], :void
|
||||
|
||||
attach_function :zip_entry_open, [:pointer, :string], :int
|
||||
attach_function :zip_entry_close, [:pointer], :void
|
||||
attach_function :zip_entry_write, [:pointer, :string, :int], :int
|
||||
end
|
||||
|
||||
ptr = Zip.zip_open("/tmp/ruby.zip", 6, "w".bytes()[0])
|
||||
|
||||
status = Zip.zip_entry_open(ptr, "test")
|
||||
|
||||
content = "test content"
|

|
||||
Zip.zip_close(ptr)

|
||||
|
||||
### Python (cffi)
|
||||
Install _cffi_ package
|
||||
```shell
|
||||
$ pip install cffi
|
||||
```
|
||||
|
||||
Bind in your package.
|
||||
```python
|
||||
import ctypes.util
|
||||
from cffi import FFI
|
||||
|
||||
ffi = FFI()
|
||||
ffi.cdef("""
|
||||
struct zip_t *zip_open(const char *zipname, int level, char mode);
|
||||
void zip_close(struct zip_t *zip);
|
||||
|
||||
int zip_entry_open(struct zip_t *zip, const char *entryname);
|
||||
int zip_entry_close(struct zip_t *zip);
|
||||
int zip_entry_write(struct zip_t *zip, const void *buf, size_t bufsize);
|
||||
""")
|
||||
|
||||
Zip = ffi.dlopen(ctypes.util.find_library("zip"))
|
||||
|
||||
ptr = Zip.zip_open("/tmp/python.zip", 6, 'w')
|
||||
|
||||
status = Zip.zip_entry_open(ptr, "test")
|
||||
|
||||
content = "test content"
|
||||
status = Zip.zip_entry_write(ptr, content, len(content))
|
||||
|
||||
Zip.zip_entry_close(ptr)
|
||||
Zip.zip_close(ptr)
|
||||
```
|
||||
|
||||
### Ring
|
||||
The language comes with RingZip based on this library
|
||||
```ring
|
||||
load "ziplib.ring"
|
||||
|
||||
new Zip {
|
||||
setFileName("myfile.zip")
|
||||
open("w")
|
||||
newEntry() {
|
||||
open("test.c")
|
||||
writefile("test.c")
|
||||
close()
|
||||
}
|
||||
close()
|
||||
}
|
||||
```
|
||||
|
||||
# Contribution Rules/Coding Standards
|
||||
No need to throw away your coding style, just do your best to follow default clang-format style.
|
||||
Apply `clang-format` to the source files before commit:
|
||||
```sh
|
||||
for file in $(git ls-files | \grep -E '\.(c|h)$' | \grep -v -- '#')
|
||||
do
|
||||
clang-format -i $file
|
||||
done
|
||||
```
