This contains a bash script to compile little C projects.
I was looking to learn about dll stuff in C and i had an idea about how i wanted to work.
The thing is i like to use the Linux terminal, so i made a compilation script to read the source code (with some considerations) and run all the necessary commands for me.
No magic, it gets the dependencies by reading the "include" instructions right from the source.
The script keeps running and detecting changes (modification dates or missing files) and runs the necessary comands.
The expected project structure is something like this:
projectFolder/
├── compileC.sh <--- add the script right here
│
└── src/ <-- source folder
│
├── main.c <-- main source file
│
└── dll.d/ <--- where the script searches for modules (dlls)
│
├── module-A/
│ └── main.c
└── module-B/
└── main.cCopy the script beside your src folder, this would look something like this:
projectFolder/
├── compileC.sh <-- compilation script
└── src/
├── main.c <-- main source file
└── ...Run the script:
./compileC.shYou will get something like this:
2023-08-13 22:43:43 : file modified since last time 'main.c'
2023-08-13 22:43:43 :> CMD: gcc -pass-exit-codes -Wextra -fmax-errors=4 -o ../bin/main.o main.c

As you can see, the script compiles everything and it show you exactly what commands is running.
And it keeps waiting for changes to recompile stuff.
Lets say i want to link some libraries like glfw, the compilation script should add something like -lglfw during execution.
I can automate this by adding some compilation notes related to each .c file, creating a .cnotes file.
Example:
projectFolder/
└── src/
├── main.c <-- compilation target
└── main.cnotes <-- added stuffAnd inside the main.cnotes file:
# this is a comment
[libs]
glfwThat is all.
I'll add stuff wen needed.
This project it is more o less structured as a C project that gives a basic idea of what i was looking to do with the compilation script.
Clone and run:
./compileC.shyou will get something like this:

Then you can edit the source files and test the "live compilation" mechanics.
Very Nice!
