### 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.

# The Idea
|
||||
<img src="zip.png" name="zip" />
|
||||
... Some day, I was looking for zip library written in C for my project, but I could not find anything simple enough and lightweight.
|
||||
Everything what I tried required 'crazy mental gymnastics' to integrate or had some limitations or was too heavy.
|
||||
I hate frameworks, factories and adding new dependencies. If I must to install all those dependencies and link new library, I'm getting almost sick.
|
||||
I wanted something powerfull and small enough, so I could add just a few files and compile them into my project.
|
||||
And finally I found miniz.
|
||||
Miniz is a lossless, high performance data compression library in a single source file. I only needed simple interface to append buffers or files to the current zip-entry. Thanks to this feature I'm able to merge many files/buffers and compress them on-the-fly.
|
||||
|
||||
It was the reason, why I decided to write zip module on top of the miniz. It required a little bit hacking and wrapping some functions, but I kept simplicity. So, you can grab these 3 files and compile them into your project. I hope that interface is also extremely simple, so you will not have any problems to understand it.
|
||||
|
||||
# Examples
|
||||
|
||||
* Create a new zip archive with default compression level.
|
||||
```c
|
||||
struct zip_t *zip = zip_open("foo.zip", ZIP_DEFAULT_COMPRESSION_LEVEL, 'w');
|
||||
{
|
||||
zip_entry_open(zip, "foo-1.txt");
|
||||
{
|
||||
char *buf = "Some data here...";
|
||||
zip_entry_write(zip, buf, strlen(buf));
|
||||
}
|
||||
zip_entry_close(zip);
|
||||
|
||||
zip_entry_open(zip, "foo-2.txt");
|
||||
{
|
||||
// merge 3 files into one entry and compress them on-the-fly.
|
||||
zip_entry_fwrite(zip, "foo-2.1.txt");
|
||||
zip_entry_fwrite(zip, "foo-2.2.txt");
|
||||
zip_entry_fwrite(zip, "foo-2.3.txt");
|
||||
}
|
||||
zip_entry_close(zip);
|
||||
}
|
||||
zip_close(zip);
|
||||
```
|
||||
|
||||
* Append to the existing zip archive.
|
||||
```c
|
||||
struct zip_t *zip = zip_open("foo.zip", ZIP_DEFAULT_COMPRESSION_LEVEL, 'a');
|
||||
{
|
||||
zip_entry_open(zip, "foo-3.txt");
|
||||
{
|
||||
char *buf = "Append some data here...";
|
||||
zip_entry_write(zip, buf, strlen(buf));
|
||||
}
|
||||
zip_entry_close(zip);
|
||||
}
|
||||
zip_close(zip);
|
||||
```
|
||||
|
||||
* Extract a zip archive into a folder.
|
||||
```c
|
||||
int on_extract_entry(const char *filename, void *arg) {
|
||||
static int i = 0;
|
||||
int n = *(int *)arg;
|
||||
printf("Extracted: %s (%d of %d)\n", filename, ++i, n);
|
||||
|
||||
return 0;
|
||||
}
|
||||
|
||||
int arg = 2;
|
||||
zip_extract("foo.zip", "/tmp", on_extract_entry, &arg);
|
||||
```
|
||||
|
||||
* Extract a zip entry into memory.
|
||||
```c
|
||||
void *buf = NULL;
|
||||
size_t bufsize;
|
||||
|
||||
struct zip_t *zip = zip_open("foo.zip", 0, 'r');
|
||||
{
|
||||
zip_entry_open(zip, "foo-1.txt");
|
||||
{
|
||||
zip_entry_read(zip, &buf, &bufsize);
|
||||
}
|
||||
zip_entry_close(zip);
|
||||
}
|
||||
zip_close(zip);
|
||||
|
||||
free(buf);
|
||||
```
|
||||
|
||||
* Extract a zip entry into memory using callback.
|
||||
```c
|
||||
struct buffer_t {
|
||||
char *data;
|
||||
size_t size;
|
||||
};
|
||||
|
||||
static size_t on_extract(void *arg, unsigned long long offset, const void *data, size_t size) {
|
||||
struct buffer_t *buf = (struct buffer_t *)arg;
|
||||
buf->data = realloc(buf->data, buf->size + size + 1);
|
||||
assert(NULL != buf->data);
|
||||
|
||||
memcpy(&(buf->data[buf->size]), data, size);
|
||||
buf->size += size;
|
||||
buf->data[buf->size] = 0;
|
||||
|
||||
return size;
|
||||
}
|
||||
|
||||
struct buffer_t buf = {0};
|
||||
struct zip_t *zip = zip_open("foo.zip", 0, 'r');
|
||||
{
|
||||
zip_entry_open(zip, "foo-1.txt");
|
||||
{
|
||||
zip_entry_extract(zip, on_extract, &buf);
|
||||
}
|
||||
zip_entry_close(zip);
|
||||
}
|
||||
zip_close(zip);
|
||||
|
||||
free(buf.data);
|
||||
```
|
||||
|
||||
|
||||
* Extract a zip entry into a file.
|
||||
```c
|
||||
struct zip_t *zip = zip_open("foo.zip", 0, 'r');
|
||||
{
|
||||
zip_entry_open(zip, "foo-2.txt");
|
||||
{
|
||||
zip_entry_fread(zip, "foo-2.txt");
|
||||
}
|

zip_entry_close(zip);
