# Ciabatta
|
|
|
|
|
|
|
|
|
|
Ciabatta - An implementation of cross-platform C standard library with the
|
|
following goals:
|
|
|
|
- Providing C standard library that fully implements all C features. Some
|
|
standard libraries lack many features of C11 and C23, like threads.h or
|
|
aligned_alloc in case of MSVCRT.
|
|
- Making standard library that is easy to port to other platforms, for example
|
|
an embedded platform or a custom operating system.
|
|
- Allowing applications to debug and step into standard library functions
|
|
(Hello MSVCRT!)
|
|
- Reasonably fast CRT compared to MSVCRT and glibc, e.g. making malloc use
|
|
a faster allocator, avoid runtime checks where possible, heavely rely on
|
|
inlining.
|
|
- Extend the possibilities of C standard library with commonly used
|
|
functionality: implementing POSIX standard, capability for unicode
|
|
processing, API to traverse directories, hash functions, better strings API,
|
|
crash handlers.
|
|
|
|
Ciabatta is not binary-compatible with other CRT libraries. That means that any
|
|
libraries that your project uses have to also be compiled with Ciabatta,
|
|
otherwise you will run into issues.
|
|
|
|
Please note that as of today ciabatta is still during development and does not
|
|
implement many of the features that need to be implemented. Using it at current
|
|
time is discouraged.
|
|
|
|
## Support
|
|
|
|
Operating System:
|
|
- Windows
|
|
- Linux
|
|
|
|
Processor Architecture:
|
|
- x86-64
|
|
|
|
This library is supposed to be extensible to other platforms, meaning that
|
|
you can write an OS layer for another OS and use the rest of the CRT
|
|
functionality.
|
|
|
|
## Building ciabatta
|
|
|
|
Before proceeding please note that ciabatta can only be compiled and used
|
|
with `clang` and `cuik`. It may be able to work with `gcc` with some minor adjustments
|
|
but I didn't test.
|
|
|
|
You can get `cuik` in [the GitHub repository](https://github.com/RealNeGate/Cuik)
|
|
|
|
For executing the script you will need at least python 3.3 and the pyjson5 package
|
|
|
|
```
|
|
$ pip install pyjson5
|
|
```
|
|
|
|
### Building
|
|
|
|
On linux you can simply run `./build.lua` script. On windows you have to run
|
|
it like `lua build.lua`. Reference for command-line options:
|
|
|
|
```
|
|
Usage: build.py [-h] [--clean] [--test TEST]
|
|
[--mode {debug,release}] [--target TARGET]
|
|
[--compiler {clang,cuik}] [--cflags [CFLAGS ...]]
|
|
Options:
|
|
-h, --help show this help message and exit
|
|
--clean Remove all object files and binaries
|
|
--test TEST Compile ciabatta executable with given file
|
|
--mode, -m {debug,release} Select build configuration
|
|
--target, -t TARGET Select target OS (default=host)
|
|
--compiler, -c {clang,cuik} Select compiler
|
|
--cflags [CFLAGS ...] Pass additional compiler flags
|
|
```
|
|
|
|
## Usage
|
|
|
|
Grab the following files into your project's (or any other) directory:
|
|
|
|
- The `./include` folder
|
|
- The `.lib` folder
|
|
- (Windows only) The `utf8` folder
|
|
|
|
In order to compile your project with ciabatta see the following sections
|
|
|
|
### Compiling with ciabatta on windows
|
|
|
|
1. Add the following flags to your compilation command:
|
|
`-nostdlib -D _CIA_OS_WINDOWS -I /include utf8.obj -mfma`
|
|
2. Add the following sources to the compile command:
|
|
`./lib/ciabatta.lib ./lib/cia.lib ./lib/crt.lib`
|
|
|
|
**Note:** The `include` folder refers to the folder you copied from ciabatta. Set the path to it accordingly.
|
|
|
|
### Compiling with ciabatta on linux
|
|
|
|
1. Add the following flags to your compilation command:
|
|
- `-nostdlib -D _CIA_OS_LINUX -I ./include -mfma`
|
|
2. Link to the following libraries
|
|
- `./lib/ciabatta.a`
