# Working
|
|
|
|
## Code
|
|
|
|
bug fixes, improvements and several other things accepted.
|
|
|
|
the coding style is described here:
|
|
|
|
- indentation: two spaces. **strictly** spaces. do NOT use tabs.
|
|
- modified 1TBS style:
|
|
- no spaces in function calls
|
|
- spaces between arguments in function declarations
|
|
- no spaces in operations except for `||` and `&&`
|
|
- no space between variable name and assignment
|
|
- space between macro in string literals
|
|
- space after comment delimiter
|
|
- C++ pointer style: `void* variable` rather than `void *variable`
|
|
- indent switch cases
|
|
- preprocessor directives not intended
|
|
- if macro comprises more than one line, indent
|
|
- no new line after `template<>`
|
|
- prefer built-in types:
|
|
- `bool`
|
|
- `signed char` or `unsigned char` are 8-bit
|
|
- when the type is `char`, **always** specify whether it is signed or not.
|
|
- unspecified `char` is signed on x86 and unsigned on ARM, so yeah.
|
|
- the only situation in where unspecified `char` is allowed is for C strings (`const char*`).
|
|
- `short` or `unsigned short` are 16-bit
|
|
- `int` or `unsigned int` are 32-bit
|
|
- `float` is 32-bit
|
|
- `double` is 64-bit
|
|
- `long long int` or `unsigned long long int` are 64-bit
|
|
- avoid using 64-bit numbers as I still build for 32-bit systems.
|
|
- two `long`s are required to make Windows happy.
|
|
- `size_t` are 32-bit or 64-bit, depending on architecture.
|
|
- in float/double operations, always use decimal and `f` if single-precision.
|
|
- e.g. `1.0f` or `1.0` instead of `1`.
|
|
- prefer `NULL` over `nullptr` or any other proprietary null.
|
|
- don't use `auto` unless needed.
|
|
- use `String` for `std::string` (this is typedef'd in ta-utils.h).
|
|
- prefer using operator for String (std::string) comparisons (a=="").
|
|
- if you have to work with C strings, only use safe C string operations:
|
|
- snprintf
|
|
- strncpy
|
|
- strncat
|
|
- any other operation which specifies a limit
|
|
|
|
some files (particularly the ones in `src/engine/platform/sound` and `extern/`) don't follow this style.
|
|
|
|
you don't have to follow this style. I will fix it after I accept your contribution.
|
|
|
|
additional guidelines:
|
|
|
|
- in general **strongly** avoid breaking compatibility.
|
|
- do not touch loadFur/saveFur unless you know what you're doing!
|
|
- new fields must be at the end of each block to ensure forward compatibility
|
|
- likewise, the instrument read/write functions in DivInstrument have to be handled carefully
|
|
- any change to the format requires a version bump (see `src/engine/engine.h`).
|
|
- do not bump the version number under any circumstances!
|
|
- if you are making major changes to the playback routine, make sure to test with older songs to ensure nothing breaks.
|
|
- I will run a test suite to make sure this is the case.
|
|
- if something breaks, you might want to add a compatibility flag (this requires changing the format though).
|
|
- do not use `#pragma once`.
|
|
- do not memcmp() structs.
|
|
- on a switch block, **always** put `default` last and not in any other position.
|
|
- I have fear of some C/C++ compilers ignoring the rest of cases upon hitting default.
|
|
|
|
## Demo Songs
|
|
|
|
just put your demo song in `demos/`! be noted there are some guidelines:
|
|
|
|
- avoid Nintendo song covers.
|
|
- avoid big label song covers.
|
|
- low effort compositions/covers may not be accepted at all.
