From 7910253db03c4dbcdb0c8a1c007d923831f03ad1 Mon Sep 17 00:00:00 2001 From: sbraconnier Date: Fri, 16 May 2025 23:28:57 -0400 Subject: [PATCH 1/2] Add the ability to manually format Javascript code This change allows the user to format code within the code editor areas. The user can format the currently selected lines or the entire document. A default hotkey of ctrl+shift+F has been added to run this action, but it may be changed by the user. Additionally, this action can be performed in the right-click context menu by selecting "Code->Format" Signed-off-by: Tony Germano Original-sign-off: https://github.com/OpenIntegrationEngine/engine/commit/132de746f6bb7d2077249a09ad35888b87a45f4d Issue: https://github.com/OpenIntegrationEngine/engine/issues/87 --- .../components/rsta/MirthRSyntaxTextArea.java | 14 +- .../rsta/MirthRSyntaxTextArea.properties | 5 + .../ui/components/rsta/RSTAPreferences.java | 1 + .../components/rsta/actions/ActionInfo.java | 1 + .../rsta/actions/FormatCodeAction.java | 105 + .../connect/util/JavaScriptSharedUtil.java | 4 +- .../com/mirth/connect/util/beautify-1.15.3.js | 4053 +++++++++++++++++ .../com/mirth/connect/util/beautify-1.6.8.js | 2481 ---------- 8 files changed, 4180 insertions(+), 2484 deletions(-) create mode 100644 client/src/com/mirth/connect/client/ui/components/rsta/actions/FormatCodeAction.java create mode 100644 server/src/com/mirth/connect/util/beautify-1.15.3.js delete mode 100644 server/src/com/mirth/connect/util/beautify-1.6.8.js diff --git a/client/src/com/mirth/connect/client/ui/components/rsta/MirthRSyntaxTextArea.java b/client/src/com/mirth/connect/client/ui/components/rsta/MirthRSyntaxTextArea.java index e2e5c5c193..86ca7c33d1 100644 --- a/client/src/com/mirth/connect/client/ui/components/rsta/MirthRSyntaxTextArea.java +++ b/client/src/com/mirth/connect/client/ui/components/rsta/MirthRSyntaxTextArea.java @@ -62,6 +62,7 @@ import com.mirth.connect.client.ui.components.rsta.actions.ExpandFoldAction;
