Actually it could be done using a simple script like this one (experimental version - bug reports/comments welcome ...) The another function splits text in separate lines using the given separator (regular expression metacharacters need to be escaped with backslash "\" )
If someone would be interested in testing it, you can simply save it e.g. to ???\PSPad\Script\JScript\join.js recompile scripts and run it from the script menu Since it is a pretty simple javascript, there might be some performance issues on larger files, so I don't think, it would be worth adding on a extensions page... //////////////////////////////////////// var module_name = "join_split_js"; var module_ver = "1"; function joinLines(){ // joins lines (in selection or in the whole document) using the given separator - default: space; // pressing Esc, clicking Cancel, or deleting the default space and clicking OK sets separator // to an empty string; once executed, can be undone via Ctrl+Z (Undo) only var actEd = newEditor(); actEd.assignActiveEditor(); var separJoin = InputText("Enter separator (joining):"," "); var joinRE = new RegExp("(\r|\n| ){2}","g"); if (actEd.selText().length > 0){ var inputTxt = actEd.selText(); var outputText = inputTxt.replace(joinRE, separJoin); actEd.selText(outputText); }else{ var inputTxt = actEd.text(); var outputText = inputTxt.replace(joinRE, separJoin); actEd.text(outputText); } } function splitLines(){ //splits lines (in selection or in the whole document) using the given separator - Regular Expression - // default: space; pressing Esc, clicking Cancel, or deleting the default space and clicking OK // sets separator to an empty string, i.e.: splits each character to a separate line; // once executed, can be undone via Ctrl+Z (Undo) only var actEd = newEditor(); actEd.assignActiveEditor(); var separSplit = InputText("Enter separator - RE - (splitting):"," "); var SplitRE = new RegExp(separSplit,"g"); if (actEd.selText().length > 0){ var inputTxt = actEd.selText(); var outputText = inputTxt.replace(SplitRE, "\n"); actEd.selText(outputText); }else{ var inputTxt = actEd.text(); var outputText = inputTxt.replace(SplitRE, "\n") actEd.text(outputText); } } function Init(){ addMenuItem("Join lines", "", "joinLines","Ctrl+Alt+J"); addMenuItem("Split lines", "", "splitLines","Ctrl+Alt+S"); } //////////////////////////////////////////////// -- <http://forum.pspad.com/read.php?2,39067,39095> PSPad freeware editor http://www.pspad.com
