| ## 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)\>" |
| color magenta "\<(split|sprintf|strtonum|sub|substr|tolower|toupper)\>" |
| color magenta "\<(mktime|strftime|systime)\>" |
| color magenta "\<(and|compl|lshift|or|rshift|xor)\>" |
| color magenta "\<(bindtextdomain|dcgettext|dcngettext)\>" |

| ## 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:]])#.*$" |
| |
| ## Trailing whitespace |
| color ,green "[[:space:]]+$" |
