Editing LshalOutputParser

=== Problem Specification 10:50 <Thanatermesis> i want to obtain the model of the disk, for example, on a lshal result, you can see your hard disk on "block.device", and in other place (of the same section-device) you see "storage.model" what i want to obtain 10:51 <Thanatermesis> lshal shows a lot of "sections", one per device, i have think to use awk in a way that the field separator be every line, and the record separator could be every "block" of this (so, every section) === Code {{{ BEGIN { skip = 1 inBlock = 0 FS = " = " } function die(msg) { printf "ERROR on line %d of input: %s\n", NR, msg >> "/dev/stderr" exit 1 } function trim(str) { sub(/^ +/, "", str) sub(/ +$/, "", str) return str } function startBlock() { split("", PROPERTIES) # delete all values in the PROPERTIES array split("", PROPORDER) # clear the ordered properties list PROPNUM = 0 # reset the order counter split("", PROPTYPES) # clear the type annotations as well parseBlockLine() } function parseBlockLine( key, val, type) { key = trim($1) match($2, /\([^\)]+\)$/) # find parenthesized strings that are last on the line if (RLENGTH > 0) { type = substr($2, RSTART+1, RLENGTH-2) # offsets to remove parentheses val = trim(substr($2, 1, (length($2) - RLENGTH))) # remove type info } else { type = "udi" val = trim($2) } #printf "!%s! ---- !%s! ---- !%s!\n", key, val, type PROPERTIES[key] = PROPORDER[PROPNUM++] = val PROPTYPES[key] = PROPTYPES[PROPNUM] = type } function endBlock() { if ("block.storage_device" in PROPERTIES && \ "storage.model" in PROPERTIES && \ length(PROPERTIES["storage.model"]) > 2) { printf "device:\t%s\nmodel:\t%s\n", PROPERTIES["block.storage_device"], PROPERTIES["storage.model"] } return } ########################################## # parser code below ########################################## $0 ~ /^(-+$|Dumped)/ {skip = ! skip; next} skip {next} # skip the header and the footer /^udi/ && (! inBlock) { inBlock = 1 startBlock() next } /^ / && inBlock { parseBlockLine() next } /^$/ && inBlock { inBlock = 0 endBlock() next } (/^udi/ && inBlock) || (/^ / && (! inBlock)) { die("Block info line encountered out of sequence, parsing error!") } }}} === Sample Output {{{ $ lshal | gawk -f ./lshal-parse device: '/org/freedesktop/Hal/devices/storage_serial_NLB9T3413AVB' model: 'FUJITSU MHS2040AT' device: '/org/freedesktop/Hal/devices/storage_model_Slimtype_COMBO_LSC_24081' model: 'Slimtype COMBO LSC-24081' $ }}}
