## Here is an example for awk.
##
syntax "awk" "\.awk$"
## records
icolor brightred "\$[0-9A-Z_!@#$*?-]+"
## awk-set variables
color red "[[:<:]](ARGC|ARGIND|ARGV|BINMODE|CONVFMT|ENVIRON|ERRNO|FIELDWIDTHS)[[:>:]]"
color red "[[:<:]](FILENAME|FNR|FS|IGNORECASE|LINT|NF|NR|OFMT|OFS|ORS)[[:>:]]"
color red "[[:<:]](PROCINFO|RS|RT|RSTART|RLENGTH|SUBSEP|TEXTDOMAIN)[[:>:]]"
## function declarations and special patterns
color brightgreen "[[:<:]](function|extension|BEGIN|END)[[:>:]]"
## operators
color green "(\{|\}|\(|\)|\;|\]|\[|\\|<|>|!|=|&|\+|-|\*|%|/|\?:|\^|\|)"
## flow control
color brightyellow "[[:<:]](for|if|while|do|else|in|delete|exit)[[:>:]]"
color brightyellow "[[:<:]](break|continue|return)[[:>:]]"
## I/O statements
color brightgreen "[[:<:]](close|getline|next|nextfile|print|printf)[[:>:]]"
color brightgreen "[[:<:]](system|fflush)[[:>:]]"
## standard functions
color magenta "[[:<:]](atan2|cos|exp|int|log|rand|sin|sqrt|srand)[[:>:]]"
color magenta "[[:<:]](asort|asorti|gensub|gsub|index|length|match)[[:>:]]"

##
## String highlighting.  You will in general want your comments and
## strings to come last, because syntax highlighting rules will be
## applied in the order they are read in.
color brightyellow "<[^= 	]*>" ""(\\.|[^"])*""

## Comment highlighting
color brightblue "(^|[[:space:]])#.*$"

## Trailing whitespace
color ,green "[[:space:]]+$"
