I tried to create a custom syntax file to read FIX messages. Note: I am certain my custom files are being loaded by Vim.The file format is sequences of NUMBER=VALUE pairs separated by the unprintable 0x1 character. I wanted a few of the pairs (the ones with important data) to turn colors when I open the file in Vim. I don't care about which colors they turn, as long as they are all different and are easily distinguishable from each other.Specifically, I want the tags associated with the following numbers to be highlighted: 44, 52, 54, 60, 9717.Here's my syntax file (~/.vim/syntax.vim)if version >= 600    if exists(b:current_syntax)         finish    endifelse    syntax clearendifsyn case ignoresyn match fixPrice \|44[=][^|]\+\|syn match fixSendingTime \|52[=][^|]\+\|syn match fixTransactTime \|60[=][^|]\+\|syn match fixCorrelation \|9717[=][^|]\+\|syn match fixSide \|54[=][^|]\+\|syn match fixPrice 44syn match fixSendingTime |52syn match fixTransactTime \|60syn match fixCorrelation \|9717syn match fixSide \|54 Define the default highlightingif version >= 508 || !exists(did_fix_syntax_inits)        if version < 508                let did_fix_syntax_inits = 1                command -nargs=+ HiLink hi link <args>        else                command -nargs=+ HiLink hi def link <args>        endif        HiLink fixPrice Label        HiLink fixSendingTime Number        HiLink fixTransactTime Include        HiLink fixCorrelation String        HiLink fixSide Identifier        delcommand HiLinkendiflet b:current_syntax = fixSample line of data:8=FIXT.1.1^A9=380^A35=X^A49=CME^A56=0^A34=13362975^A52=20130626135401572^A1128=9^A268=3^A279=0^A269=2^A48=42025^A22=8^A270=-224^A271=1^A273=135401000^A274=2^A451=32^A1020=23^A83=523628^A5799=1^A5797=1^A279=0^A269=2^A48=17311^A22=8^A270=12356^A271=1^A273=135401000^A277=1^A451=-395^A1020=201377^A83=5671131^A5797=1^A279=0^A269=2^A48=122816^A22=8^A270=12580^A271=1^A273=135401000^A274=2^A277=1^A451=-427^A1020=31^A83=1396693^A5797=2^A75=20130626^A10=001^ANote that the ^A characters are the 0x1 unprintable characters, you can fix this file with::%s/\^A/<01>/Where <01> is entered with Ctrl+v followed by 001.
