flatten_html.sh: This script "flattens" an HTML file by inlining all
|
||
|
|
files included via "#include virtual". This is useful when making
|
||
|
|
changes to the Kafka documentation files.
|
||
|
|
|
||
|
|
Typical usage:
|
||
|
|
./gradlew docsJar
|
||
|
|
./tests/bin/flatten_html.sh -f ./docs/protocol.html > /tmp/my-protocol.html
|
||
|
|
firefox /tmp/my-protocol.html &
|
||
|
|
|
||
|
|
usage:
|
||
|
|
$0 [flags]
|
||
|
|
|
||
|
|
flags:
|
||
|
|
-f [filename] The HTML file to process.
|
||
|
|
-h Print this help message.
