Hi,
I'm trying to make some helper macros for placing ANSI terminal codes (ie. for changing text colour or making it bold):

Code:

; Example usage

msg db ansi_bold, 'Hello world!', 0x0A

At this moment my version is as follows:

Code:

ESC = 0x1B ; Escape character
macro escape ansi_code { store ESC, ansi_code at . }
macro ansi_bold        { escape '[1m' }          ; Set "bright" attribute
macro ansi_fg_red      { escape '[31m' }         ; Set foreground to color #1 - red

But this is not working, obviously I'm doing something wrong. Would someone help me with it?

Make highlightings with such method worst thing.

I think all such decorations should be stay of code syntax.
for such purpose use comments.

Code:

msg db 'Hello world!', 0x0A ; #HL# ansi_bold quotedtext

than tell highlight function to detect content of comments

I think everything out of valuable source code should be in comments
I think about something closer - code folding. place in comment #+ or #- that would be hidden in IDE but according such comment code will be folded or not.

fasm doesn't support inline macros. Instead you can use equ.

Code:

ESC     equ     0x1B
BOLD    equ     ESC,'[1m'
FG_RED  equ     ESC,'[31m'

msg db BOLD, 'Hello world!', 0x0a
