How to build the custom ACE modes for Node-RED
|
||
|
|
----------------------------------------------
|
||
|
|
|
||
|
|
Node-RED includes custom JSONata and JavaScript modes.
|
||
|
|
|
||
|
|
|
||
|
|
## JSONata
|
||
|
|
|
||
|
|
The `ace/mode/jsonata` mode is maintained under `editor-client/src/vendor/jsonata`.
|
||
|
|
Those files are edited in place and copied into the build by Grunt.
|
||
|
|
|
||
|
|
## JavaScript
|
||
|
|
|
||
|
|
The `ace/mode/nrjavascript` mode is used exclusively by the Function node. It
|
||
|
|
inherits almost entirely from the normal JavaScript mode. The one key difference
|
||
|
|
is that it wraps the code with a Function before parsing. This is required to
|
||
|
|
avoid some false-flagged errors.
|
||
|
|
|
||
|
|
The source of the mode is under `editor-client/src/ace/mode`. If those files are
|
||
|
|
modified in anyway, they *must* be manually built to generate the files under
|
||
|
|
`editor-client/src/ace/bin` and checked in. Those files are the ones the Grunt
|
||
|
|
built copies out in the Node-RED build.
|
||
|
|
|
||
|
|
### Building the mode files
|
||
|
|
|
||
|
|
|
||
|
|
#### Setup build environment
|
||
|
|
|
||
|
|
cd /tmp/
|
||
|
|
git clone https://github.com/ajaxorg/ace.git
|
||
|
|
cd ace
|
||
|
|
npm install
|
||
|
|
|
||
|
|
#### Copy mode src files into build environment
|
||
|
|
|
||
|
|
cd <node-red-source-directory
|
||
|
|
cp packages/node_modules/@node-red/editor-client/src/ace/mode/* \
|
||
|
|
/tmp/ace/lib/ace/mode/
|
||
|
|
|
||
|
|
#### Run the build
|
||
|
|
|
||
|
|
cd /tmp/ace
|
||
|
|
node ./Makefile.dryice.js -m -nc
|
||
|
|
|
||
|
|
#### Copy the built versions back
|
||
|
|
|
||
|
|
cp build/src-min-noconflict/*-nrjavascript.js \
|
||
|
|
<node-red-source-directory>/packages/node_modules/@node-red/editor-client/src/ace/bin/
|
||
|
|
cp build/src-min-noconflict/snippets/nrjavascript.js \
|
||
|
|
<node-red-source-directory>/packages/node_modules/@node-red/editor-client/src/ace/bin/snippets/
