hightlight syntax problem

[Ni Va]

Hi all,

Considering this kind of line:

      SPB   ERR2; 

With in my syntax file these syntax pattern recognition:

syn match s7JumpsOperand    /^\s\+\zs\(SPA\|SPL\|SPBNB\|SPBN\|SPBB\|SPB\|SPBI\|SPBIN\|SLW\|SPO\|SPS\|SPZ\|SPN\|SPP\|SPM\|SPPZ\|SPMZ\|SPU\|LOOP\)\ze/

syn match s7JumpsLabel         /^\(\s\+SPB\s\+\)\zs\([^;]\+\)\ze;/

HiLink s7JumpsOperand        JumpsColorDarkRed

HiLink s7JumpsLabel             JumpsColorDarkRed

Why it highlights only first SPB Operand and no ERR2 like that ?

      SPB   ERR2; 

Thank you

They both try to match at the same location, because you implicitly
anchored your match. For that kind of thing you can use nextgroup e.g.

:syn match s7JumpsOperand /SPB\ze\s\+/ nextgroup=s7JumpLabel
:syn match s7JumpLabel /ERR2\ze;$/


Best,
Christian

 i tried this 

syn match s7JumpsOperand    /^\s\+\zs\(SPA\|SPL\|SPBNB\|SPBN\|SPBB\|SPB\|SPBI\|SPBIN\|SLW\|SPO\|SPS\|SPZ\|SPN\|SPP\|SPM\|SPPZ\|SPMZ\|SPU\|LOOP\)\ze/ nextgroup=s7JumpLabel

syn match s7JumpsLabel      /^\s\+\S\+\s\+\zs\([^;]\+\)\ze;/

It does not highlight second group s7JumLabel because of same location ... how to avoid this ?

Remove the anchoring at the start of the line for Label group

Tried with 

syn match s7JumpsOperand    /^\s\+\zs\(SPA\|SPL\|SPBNB\|SPBN\|SPBB\|SPB\|SPBI\|SPBIN\|SLW\|SPO\|SPS\|SPZ\|SPN\|SPP\|SPM\|SPPZ\|SPMZ\|SPU\|LOOP\)\ze/ nextgroup=s7JumpLabel

syn match s7JumpsLabel      /\s\+\S\+\s\+\zs\([^;]\+\)\ze;/

do that:

well, also remove the matching from the previous group. s7JumpsOperand
already matched the part before the \zs of the s7Jumpslabel, so why add
it here again? That cannot happen to match.

Effectively,  just want to match and highlight with two colors the two sentence like above:

      SPB _003;

So, the first no need to specify nextgroup I thought:

syn match s7JumpsOperand   /^\s\+\zs\(SPA\|SPL\|SPBNB\|SPBN\|SPBB\|SPB\|SPBI\|SPBIN\|SLW\|SPO\|SPS\|SPZ\|SPN\|SPP\|SPM\|SPPZ\|SPMZ\|SPU\|LOOP\)\ze/

the second has to know if it is preceeded by the first to highlight:

for example: syn match s7JumpsLabels    \(SPBNB\s\+\)\@<=\([^;]\+\)\ze;  but it has same location......

[Ni Va]

This seems to work

syn match s7JumpsOperand    /^\s\+\zs\(SPA\|SPL\|SPBNB\|SPBN\|SPBB\|SPB\|SPBI\|SPBIN\|SLW\|SPO\|SPS\|SPZ\|SPN\|SPP\|SPM\|SPPZ\|SPMZ\|SPU\|LOOP\)\ze/

syn match s7JumpsLabel      /\(SPB\s\+\)\@<=\([^; ]\+\)\ze;/
