From ff72467c108bc7fb91726730a35aa8dc59d177d9 Mon Sep 17 00:00:00 2001 From: Julian Viereck Date: Wed, 27 Apr 2011 21:40:13 +0200 Subject: [PATCH] Remove FoldLine.getRowLength and .getRowSplits. Use already existing functions which simplifies the code. --- lib/ace/edit_session.js | 159 ++++++++++++++++++++++------------- lib/ace/edit_session_test.js | 3 +- lib/ace/layer/text.js | 2 +- lib/ace/test/all_browser.js | 40 ++++----- 4 files changed, 122 insertions(+), 82 deletions(-) diff --git a/lib/ace/edit_session.js b/lib/ace/edit_session.js index 203cb330..c922f115 100644 --- a/lib/ace/edit_session.js +++ b/lib/ace/edit_session.js @@ -1002,29 +1002,31 @@ var EditSession = function(text, mode) { var tabSize = this.getTabSize(); var wrapData = this.$wrapData; var wrapLimit = this.$wrapLimit; + var tokens; for (var row = firstRow; row <= lastRow; row++) { + tokens = this.$getDisplayTokens(lang.stringTrimRight(lines[row])); wrapData[row] = - this.$computeWrapSplits(lines[row], wrapLimit, tabSize); + this.$computeWrapSplits(tokens, wrapLimit, tabSize); } }; // "Tokens" var CHAR = 1, CHAR_EXT = 2, - SPACE = 3, - TAB = 4, - TAB_SPACE = 5; + PLACEHOLDER_START = 3, + PLACEHOLDER_BODY = 4, + SPACE = 10, + TAB = 11, + TAB_SPACE = 12; - this.$computeWrapSplits = function(textLine, wrapLimit, tabSize) { - textLine = lang.stringTrimRight(textLine); - if (textLine.length == 0) { + this.$computeWrapSplits = function(tokens, wrapLimit, tabSize) { + if (tokens.length == 0) { return []; } var tabSize = this.getTabSize(); var splits = []; - var tokens = this.$getDisplayTokens(textLine); var displayLength = tokens.length; var lastSplit = 0, lastDocSplit = 0; @@ -1035,11 +1037,11 @@ var EditSession = function(text, mode) { // and multipleWidth characters. var len = displayed.length; displayed.join(""). - // Get all the tabs spaces. - replace(/5/g, function(m) { + // Get all the TAB_SPACEs. + replace(/12/g, function(m) { len -= 1; }). - // Get all the multipleWidth characters. + // Get all the CHAR_EXT/multipleWidth characters. replace(/2/g, function(m) { len -= 1; }); @@ -1053,43 +1055,103 @@ var EditSession = function(text, mode) { // This is, where the split should be. var split = lastSplit + wrapLimit; - // If there is a space or tab at this split position. + // If there is a space or tab at this split position, then making + // a split is simple. if (tokens[split] >= SPACE) { // Include all following spaces + tabs in this split as well. while (tokens[split] >= SPACE) { split ++; } addSplit(split); - } else { - // Search for the first non space/tab token. + continue; + } + + // === ELSE === + // Search for the first non space/tab token backwards. + for (split; split != lastSplit - 1; split--) { + if (tokens[split] >= SPACE) { + split++; + break; + } + } + // If we found one, then add the split. + if (split > lastSplit) { + addSplit(split); + continue; + } + + // === ELSE === + split = lastSplit + wrapLimit; + // No space or tab around?
