# threaded network chat refactor
|
||||
|
||||
The code has been refactored and it compiles. Hopefully it won't explode, but we were going to be
|
||||
doing a bunch of bug fixes anyway.
|
||||
|
||||
## What now?
|
||||
|
||||
See TODO. From here we're going to push the code to the gitlab like we were told to after everyone
|
||||
is set up. Follow the coding style guidelines because otherwise everything will be extremely gross
|
||||
and inconsistent. If you set up your editor correctly, it will take care of most of that stuff.
|
||||
|
||||
## TODO
|
||||
|
||||
- Finalize coding style,
|
||||
- **see [STYLE.md](STYLE.md)**
|
||||
- Get everyone's editors set up for clangd/clang-format and git
|
||||
- Make sure everyone's compiler toolchains work
|
||||
- Decide who gets what responsibilities
|
||||
- Distribute appropriate code to people with those responsibilities
|
||||
- Have everyone upload their respective code to their sections of the gitlab
|
||||
|
||||
## Code
|
||||
|
||||
Everything is in [src/](src).
|
||||
A mostly untouched copy of [Scott's original code](https://git.therats.win/scott/threaded_network_chat) is also in [old/](old).
|
||||
A reformatted version of that code is also in [modified-example.cc](modified-example.cc) but it can be ignored.
|
||||
|
||||
## Build
|
||||
|
||||
```
|
||||
cd src/
|
||||
make
|
||||
```

I'm trying to split this up into multiple pieces but that probably involves using fewer global variables and passing the
|
||||
same data between the functions that use them.
|
||||
|
||||
global variables will use `snake_case` and global constants will use `SCREAMING_SNAKE_CASE`.
