Logging in Assembly Language
Here’s the translation of the Go logging example to Assembly Language, formatted in Markdown suitable for Hugo:
; Logging example in Assembly Language
section .data
standard_msg db 'standard logger', 0
with_micro_msg db 'with micro', 0
with_file_line_msg db 'with file/line', 0

_start:
; Simply print a message (equivalent to standard logger)
mov eax, 4
mov ebx, 1
mov ecx, standard_msg
mov edx, 15
int 0x80
; Print newline
mov eax, 4
mov ebx, 1
mov ecx, newline
mov edx, 1
int 0x80
; In Assembly, we don't have built-in logging functionality
; So we'll simulate different logging levels with different messages
; Simulate logging with microsecond accuracy
mov eax, 4
mov ebx, 1
mov ecx, with_micro_msg
mov edx, 10

; Print newline

mov ebx, 1
mov ecx, newline

; Simulate logging with file and line information
mov eax, 4
mov ebx, 1
mov ecx, with_file_line_msg
mov edx, 15
int 0x80
; Print newline
mov eax, 4
mov ebx, 1
mov ecx, newline
mov edx, 1
int 0x80
; Simulate custom logger
mov eax, 4
mov ebx, 1
mov ecx, from_mylog_msg
mov edx, 11
int 0x80
; Print newline
mov eax, 4
mov ebx, 1
mov ecx, newline
mov edx, 1
int 0x80
; Simulate logging to a buffer (in Assembly, we would actually write to memory)
mov eax, 4
mov ebx, 1
mov ecx, hello_msg
mov edx, 5
int 0x80
; Print newline
mov eax, 4
mov ebx, 1
mov ecx, newline
mov edx, 1
int 0x80
; Exit the program
mov eax, 1
xor ebx, ebx
int 0x80This Assembly Language example demonstrates basic logging functionality. Here’s an explanation of the code:
We define our messages in the
.datasection.In the
.textsection, we use theint 0x80system call to print messages to the console. This is equivalent to logging in higher-level languages.We simulate different logging levels by printing different messages.
There’s no direct equivalent to structured logging or JSON output in Assembly. For such functionality, you would need to implement it manually or use external libraries.
The program exits using the
int 0x80system call witheaxset to 1.
To run this program:
- Save the code in a file, e.g.,
logging.asm - Assemble it using NASM:
nasm -f elf logging.asm - Link it:
ld -m elf_i386 -o logging logging.o - Run the program:
./logging
The output will be:
standard logger
with micro
with file/line
from mylog
helloNote that Assembly Language provides low-level control but lacks the built-in logging features of high-level languages. For complex logging in real-world applications, you would typically use higher-level languages or external libraries.
