Syntax Coloring in µVision 2

Christophe Champigny

May be a stupid question...

But, is it possible to add new syntax coloring in µVision ?

I saw that Keil give six different colors for background, keywords, string, .... So, is it possible to create a new type of coloring syntax ?

I saw that some .INI files in the µVision directory contain all keywords! Is there a place like this file to create a new syntax coloring ?

Why I would like to do that ? Because, I would like that C keywords and 8051 SFR's appears with 2 differents colors when i'm coding in C.

    "I would like that C keywords and 8051 SFR's appears with 2 differents colors when i'm coding in C."

    Yes, that'd be good.
    I suggested this to Keil a while back, but no answer yet...

    I think you can just add keywords to the C51.INI file; eg, I think I once added defined, as uVision doesn't automatically highlight it!
    I think I just added

    defined=C
    in the [Keywords] section

    I had a few tries at getting different-coloured highlighting, but no luck :-(
    Probably easier to use CodeWright instead!

    Me too i try some change in the C51.INI file, but nothing change in µVision.

    I search the register base, and find many keys who define the syntax coloring. I try to add some but, I don't know if Keil accept some new syntax.

    Well, uVision v2.23 still doesn't highlight the defined ANSI 'C' keyword as standard; so I've just added it again.

    The procedure is:
    1. Open C51.INI in Notepad
    2. Add a line "defined=C" in the [Keywords] Section (I don't know if it must be in alphabetical order, but I did anyway).
    3. Save & Close C51.INI

    Next time you start uVision, defined will be coloured just like all the other 'C' keywords.

    At the top of the C51.INI, we see:

    [Colors]
C=0,0,255
CXX=128,0,128
CPP=0,0,128
    which look like RGB colour specs for the keywords;
    certainly "C=0,0,255" seems to correspond to the blue highlighting which I see (Red=0, Green=0, Blue=255)

    However, if I change an entry to, for example, "defined=CXX" it makes absolutely no difference at all - defined is still coloured blue, just like all the other 'C' keywords!

    Ho Hum.
    Maybe someone from Keil can shed some light (or colour!) on this?

    Yes! I already did this test ! And I've got no difference!

    In a first step, I try to change the value C=0,0,255 (me too i thought about RVB code) in value: C=255,0,0. But this gives also no changes.

    In a second step, i search the register base (with the word KEIL and found this:
    some keys defined the syntax coloring, there is a key: "keywords" who contain the string "c51.ini" and another key: "keyword" who contain "0,0,255". I try to change some value, like "0,0,255" in "255,0,0". And Keil change my blue settings in a red settings ! So I found the place where Keil save his parameters. But my next tries doesn't gives me some new success in my quest of the syntax coloring !

    I try to had some new keys, but without any success.

    May be Keil now if µVision accept some correction somewhere to had some new syntax coloring ?
