-* Ported NoFlo core from CoffeeScript to ES6 +* Ported NoFlo from CoffeeScript to ES6 * Deprecated constructing networks with `new noflo.Network`. Use `noflo.createNetwork` instead, with the following options available: - `subscribeGraph: true`: Uses `LegacyNetwork` which modifies network topology based on changes in graph. This can cause some types of errors to be silent. - `subscribeGraph: false`: Uses `Network`: network topology can be changed with network's methods (`addNode`, `removeEdge`, etc) and will be also written to the graph. For backwards compatibility reasons, `subscribeGraph` defaults to `true`. Adapt your applications to use `false` instead and start utilizing Network methods for any changes to a running graph. * Added support for a more standard `noflo.createNetwork(graph, options, callback)` signature, with backwards compatibility for the legacy `noflo.createNetwork(graph, callback, options)` signature +* Removed support for `noflo.WirePattern`. WirePattern has been deprecated since 1.0, and all code using it should be migrated to the latest Process API +* Removed support for changing component icon and description statically (on class level) at run-time (i.e. `ComponentName::icon = 'new-icon'`). Component icon and description should be set in class constructor or in `getComponent` instead. Changing icon and description for a specific instance (process) is not affected and is fully supported ## 1.1.3 (April 12th 2018) From 2e6ba68c3fb99b4b66bce06f8823c0250282fbaa Mon Sep 17 00:00:00 2001 From: Vladimir Sibirov Date: Fri, 24 Jul 2020 21:46:52 +0200 Subject: [PATCH 203/215] Prepare examples for decaffeination --- examples/http/HelloController.coffee | 2 ++ examples/http/hello.coffee | 1 + examples/linecount/count.coffee | 1 + 3 files changed, 4 insertions(+) diff --git a/examples/http/HelloController.coffee b/examples/http/HelloController.coffee index e08b54237..479314146 100644 --- a/examples/http/HelloController.coffee +++ b/examples/http/HelloController.coffee @@ -17,3 +17,5 @@ exports.getComponent = -> data: locals: string: "Hello, #{request.req.remoteUser}" + return + return c diff --git a/examples/http/hello.coffee b/examples/http/hello.coffee index d39bf872c..15fc20278 100644 --- a/examples/http/hello.coffee +++ b/examples/http/hello.coffee @@ -31,3 +31,4 @@ noflo.createNetwork graph, (err) -> if err console.error err process.exit 1 + return diff --git a/examples/linecount/count.coffee b/examples/linecount/count.coffee index d6acb67b9..8e0f1fff6 100644 --- a/examples/linecount/count.coffee +++ b/examples/linecount/count.coffee @@ -27,3 +27,4 @@ noflo.createNetwork graph, (err) -> if err console.error err process.exit 1 + return From a2d73bf9ebf8d312be92b21b6d8bcd7b80ba46aa Mon Sep 17 00:00:00 2001 From: decaffeinate Date: Fri, 24 Jul 2020 21:47:24 +0200 Subject: [PATCH 204/215] decaffeinate: Rename HelloController.coffee from .coffee to .js --- examples/http/{HelloController.coffee => HelloController.js} | 0 1 file changed, 0 insertions(+), 0 deletions(-) rename examples/http/{HelloController.coffee => HelloController.js} (100%) diff --git a/examples/http/HelloController.coffee b/examples/http/HelloController.js similarity index 100% rename from examples/http/HelloController.coffee rename to examples/http/HelloController.js From 847de043bebfa316d8505ce55981fac792ccabb7 Mon Sep 17 00:00:00 2001 From: decaffeinate Date: Fri, 24 Jul 2020 21:47:25 +0200 Subject: [PATCH 205/215] decaffeinate: Convert HelloController.coffee to JS --- examples/http/HelloController.js | 44 +++++++++++++++++--------------- 1 file changed, 24 insertions(+), 20 deletions(-) diff --git a/examples/http/HelloController.js b/examples/http/HelloController.js index 479314146..b6e202c7b 100644 --- a/examples/http/HelloController.js +++ b/examples/http/HelloController.js @@ -1,21 +1,25 @@ -noflo = require "noflo" +const noflo = require("noflo");
