From 011c197aeedab56d501b03b800433dd0cd9bc4f7 Mon Sep 17 00:00:00 2001 From: "(quasar) nebula" Date: Wed, 30 Aug 2023 16:28:47 -0300 Subject: data: always define composite utilities with `key() {}` syntax Sublime Text doesn't index the key in `key: () => {}` as a symbol for function definitions if the parameter list takes up more than one line, but always works for `key() {}`. This also just makes it a little easier to add "preamble" before the main return value, when relevant. Consistent syntax is usually a plus for recurring behavioral forms! --- src/data/things/thing.js | 121 +++++++++++++++++++++++++++------------------- src/data/things/track.js | 123 ++++++++++++++++++++++++++--------------------- 2 files changed, 140 insertions(+), 104 deletions(-) (limited to 'src') diff --git a/src/data/things/thing.js b/src/data/things/thing.js index 6bdc897f..cd62288e 100644 --- a/src/data/things/thing.js +++ b/src/data/things/thing.js @@ -1151,20 +1151,24 @@ export default class Thing extends CacheableObject { // compositional step, the property will be exposed as undefined instead // of null. // - exposeDependency: (dependency, {update = false} = {}) => ({ - annotation: `Thing.composite.exposeDependency`, - flags: {expose: true, update: !!update}, + exposeDependency(dependency, { + update = false, + } = {}) { + return { + annotation: `Thing.composite.exposeDependency`, + flags: {expose: true, update: !!update}, - expose: { - mapDependencies: {dependency}, - compute: ({dependency}) => dependency, - }, + expose: { + mapDependencies: {dependency}, + compute: ({dependency}) => dependency, + }, - update: - (typeof update === 'object' - ? update - : null), - }), + update: + (typeof update === 'object' + ? update + : null), + }; + }, // Exposes a constant value exactly as it is; like exposeDependency, this // is typically the base of a composition serving as a particular property @@ -1172,20 +1176,24 @@ export default class Thing extends CacheableObject { // exit with some other value, with the exposeConstant base serving as the // fallback default value.
