chromedp-gen is a standalone tool for the chromedp
project that generates the types for the Chrome Debugging Protocol Domain APIs
as defined in Chrome's protocol.json.
Run update.sh to retrieve and combine the latest
browser_protocol.json and
js_protocol.json
from the Chromium source tree into protocol.json.
chromedp-gen uses the qtc,
easyjson, and
goimports tools for generating
templates for the various CDP domains, for generating fast JSON
marshaler/unmarshalers, and for code formatting (and fixing missing imports),
respectively.
chromedp-gen expects these tools to be somewhere on your $PATH. Please
ensure that $GOPATH/bin is on your $PATH, and then install these tools (and
their associated dependencies) in the usual Go way:
$ go get -u \
github.com/valyala/quicktemplate/qtc \
github.com/mailru/easyjson/easyjson \
golang.org/x/tools/cmd/goimportsAssuming the qtc, easyjson, and goimports commands are available on
$PATH (see above), simply run the build.sh to generate the
domain protocol types for chromedp command.
The output of running update.sh and build.sh is below:
# change to chromedp-gen path
$ cd $GOPATH/src/github.com/chromedp/chromedp-gen
# update protocol.json to master
$ ./update.sh
