RLIB

Collection of frequently used C functions by me.

It contains

• An advanced benchmark system.
• An alternative to printf supporting printing of time between messages for e.g. benchmarking. and colors.
• Super fast tree map (much faster than hash table).
• Stdout redirection.
• Terminal progress bar.
• Multi purpose lexer.
• Custom malloc for counting allocations and free's.
• Simple test library that works like assert that also checks memory if rmalloc is used and creates summary and provides exit code.
• Several time functions supporting nano seconds.
• Several math functions for if not available by std (on termux for example).
• Arena blazing fast memory.

Extensive tested and benchmarked

All files get merged together to one file called rlib.c that can be used as a header file. The result is a single header framework.

ENVIRONMENT VARIABLES

Disabling color

Set env RDISABLE_COLORS = 1 to disable color on stdout. stderr will still have colors for gui.

Compiler and Flags

• CC = gcc : Specifies the C compiler (GCC).
• CFLAGS = -Wall -Wextra -Ofast : Compiler flags:
  • -Wall : Enable all warnings.
  • -Wextra : Enable extra warnings.
  • -Ofast : Optimize for speed.
• LDFLAGS = -lm : Linker flags to link with the math library.

Main Targets

all:

Runs the following steps in sequence:

• Testing ( test_* targets).
• Formatting code ( format_all ).
• Building the project ( build ).
• Installing executables ( install ).

format_all:

Runs clang-format to format all .c , .h , and .cpp files in the directory.

build:

Builds the rlib shared library ( librlib.so ) and an executable rlibso that uses this library:

• Compiles rlib.c into librlib.so .
• Compiles rlibso.c linking it with librlib.so .
• Runs the rlibso executable.

install:

Installs the rmerge and clean executables to /usr/bin using sudo .

Testing Targets ( test_* )

Each test_* target follows these steps:

build_*:

Compiles a specific .c file into an executable in the ./build directory.

run_*:

Runs the corresponding executable.

Example for rlexer :

• build_rlexer: Compiles rlexer.c to ./build/rlexer .
• run_rlexer: Runs ./build/rlexer .

Backup

backup:

Compresses the source files, Makefile, and additional project files into a rlib.rzip archive.

Special Cases

test_rbench_cpp:

Builds and runs a C++ benchmark program:

• Compiles rbench.cpp along with other necessary files.
• Runs the resulting executable.

Other Targets

format_rlib_c:

Specifically formats the rlib.c file.

build_*:

Targets that compile source files into executables.

run_*:

Targets that run the compiled executables.
