I want to change the behavior of the editor such that when the user presses enter on an empty list bullet, their cursor position is reset to the start of the line (rather than leaving them at the indented amount).
I've tried:
aceEdit.moveCursorTo(rowToUpdate, 0)
aceEdit.getSession().indentRows(rowToUpdate, rowToUpdate, "")
aceEdit.getSession().replace(range(rowToUpdate, 0, rowToUpdate, 0), "")
However, all three of these leave the cursor at the previous indent level. How do I reset the indent level for the line?
Update: adding example.
* list
* list
* list
* <- user presses enter here
_
Cursor is where I placed the underscore above, and can't be reset programmatically to the start of the line using what I listed above. (User can backspace the indents to get back to the start.)
You can use editor.setOption("enableAutoIndent", false) to disable automatic indentation.
If you want a way to keep autoIndent in all cases except the list, try creating an issue on ace's github page
If you want to remove the indentation on particular line you can do
var range = ace.Range
var cursor = editor.getCursorPosition()
var line = editor.session.getLine(cursor.row)
var match = /^\s*\*\s*/
if (match) {
editor.session.replace(new Range(cursor.row, 0, cursor.row, cursor.column), "")
}
If you are making a custom mode, you can give it a custom $outdent and related methods - see MatchingBraceOutdent, for example. I think the full set of indentation-related Mode methods is:
getNextLineIndent
checkOutdent
autoOutdent

Is there a way/plugin in sublime text 3 for highlighting multiple character offset ranges? The ideal desired functionality would be something like this: given a range of character offsets (e.g. 200-400, 5000-5300, 6400-6450) highlight the corresponding ranges.
This can be done with a WindowCommand plugin. Go to Tools -> New Plugin... and replace the contents with the following:
import sublime
import sublime_plugin
class SelectRegionCommand(sublime_plugin.WindowCommand):
def highlight_region(self, regions):
region_list = []
if "," in regions:
for region in regions.split(","):
region_list.append(tuple(region.split("-")))
else:
region_list.append(tuple(regions.split("-")))
view = self.window.active_view()
view.show(int(region_list[0][0]))
for region in region_list:
begin = int(region[0])
end = int(region[1])
to_highlight = sublime.Region(begin, end)
view.sel().add(to_highlight)
def run(self):
message = "Enter offset range(s) to select, separated by commas:"
default = "0-100"
self.window.show_input_panel(message, default, self.highlight_region, None, None)
Save the file as Packages/User/select_region.py (it should open that directory automatically), where Packages is the directory opened by selecting Preferences -> Browse Packages....
Next, create a custom key binding to trigger the plugin. Open Preferences -> Key Bindings-User and add the following line:
{ "keys": ["ctrl+alt+shift+s"], "command": "select_region" }
If the file is empty, surround the key binding with square brackets [ ]. Save the file, and you're all set. Hitting CtrlAltShiftS will bring up an input panel at the bottom of the window where you can enter the character offsets. Please don't include any spaces, so your input should look like the following:
Hit Enter, and the regions you entered will be selected:
EDIT
I altered the code slightly so that the view scrolls to the beginning of the first region entered (it should be centered on the screen). If you don't want that functionality for some reason, just comment out the view.show(int(region_list[0][0])) line (line 14).
I am using data validation rules on a Google Spreadsheet.
In my scenario, I need users to entry only valid values. I use the 'Reject input' to force them to write only validated content.
However, the 'Reject input' option works for manually entried data only, but it does not work if the user pastes content into the cell from a different source (e.g. a MS Excel document). In that case, a warning is still shown but the invalid value is written.
In other words, I need the 'Reject input' option to work also with pasted content.
OR... another approach would be to programmatically check the validity of the value according the Datavalidation rule for that cell.
Any ideas?
Thank you in advance.
I had a little play with this.
I had inconsistent behavior from google.
On occasion when I ctrl-c and ctrl-p, the target cell lost its data validation!
To do this programmatically
Write myfunction(e)
Set it to run when the spreadsheet is edited, do this by Resources>Current Project's Triggers
Query e to see what has happened.
Use the following to gather parameters
var sheet = e.source.getActiveSheet();
var sheetname = sheet.getSheetName();
var a_range = sheet.getActiveRange();
var activecell = e.source.getActiveCell();
var col = activecell.getColumn();
var row = activecell.getRow();
You may wish to check a_range to make sure they have not copied and pasted multiple cells.
Find out if the edit happened in an area that you have data validated;
if (sheetname == "mySheet") {
// checking they have not just cleared the cell
if (col == # && activecell.getValue() != "") {
THIS IS WHERE YOU CHECK THE activecell.getValue() AGAINST YOUR DATA VALIDATION
AND USE
activecell.setValue("") ;
to clear the cell if you want to reject the value
}
}
The obvious problem with this is that it is essentially repeating programmatically what the data validation should already be doing.
So you have to keep two sets of validation rules synchronized. You could just delete the in sheet data validation but I find that useful for providing the user feedback. Also is the data validation you are using provides content it is practical to leave it in place.
It would be great if there was a way of detecting that ctrl-p had been used or one of the paste-special options and only run the script in those cases. I would really like to know the answer to that. Can't find anything to help you there.
Note also that if someone inserts a row, this will not trigger any data validation and the onEdit() trigger will not detect it. It only works when the sheet is edited and by this I think it means there is a content change.
onChange() should detect insertion, it is described as;
Specifies a trigger that will fire when the spreadsheet's content or
structure is changed.
I am posting another answer because this is a programmatic solution.
It has a lot of problems and is pretty slow but I am demonstrating the process not the efficiency of the code.
It is slow. It will be possible to make this run faster.
It assumes that a single cell is pasted.
It does not cater for inserting of rows or columns.
This is what I noticed
The onEdit(event) has certain properties that are accessible. I could not be sure I got a full listing and one would be appreciated. Look at the Spreadsheet Edit Events section here.
The property of interest is "e.value".
I noticed that if you typed into a cell e.value = "value types" but if you pasted or Paste->special then e.value = undefined. This is also true for if you delete a cell content, I am not sure of other cases.
This is a solution
Here is a spreadsheet and script that detects if the user has typed, pasted or deleted into a specific cell. It also detects a user select from Data validation.
Type, paste or delete into the gold cell C3 or select the dropdown green cell C4.
You will need to request access, if you can't wait just copy & paste the code, set a trigger and play with it.
Example
Code
Set the trigger onEdit() to call this or rename it to onEdit(event)
You can attach it to a blank sheet and it will write to cells(5,3) and (6,3).
function detectPaste(event) {
var sheet = event.source.getActiveSheet();
var input_type =" ";
if (event.value == undefined) { // paste has occured
var activecell = event.source.getActiveCell();
if (activecell.getValue() == "") { // either delete or paste of empty cell
sheet.getRange(5,3).setValue("What a good User you are!");
sheet.getRange(6,3).setValue(event.value);
input_type = "delete"
}
else {
activecell.setValue("");
sheet.getRange(5,3).setValue("You pasted so I removed it");
sheet.getRange(6,3).setValue(event.value);
input_type = "paste";
}
}
else { // valid input
sheet.getRange(5,3).setValue("What a good User you are!");
sheet.getRange(6,3).setValue(event.value);
input_type = "type or select";
}
SpreadsheetApp.getActiveSpreadsheet().toast('Input type = ' + input_type, 'User Input detected ', 3);
}
I have a GTK# TextView and I want to read the line of text under the cursor. I don't see a single method that will do that, so I think I need to combine several method calls, like Buffer.GetText, Buffer.GetIterAtOffset, Buffer.CursorPosition, but it's not obvious to me what the right combination is.
TextIter are a bit odd to use. Buffer.CursorPosition gives you the current position.
It's easy to find the end of the line:
var end = Buffer.CursorPosition;
end.ForwardToLineEnd();
To get the first character, there's not symetrical method, so you might try:
var start = Buffer.CursorPosition;
start.BackwardChars(start.LineOffset); // LineOffset gives you the iter offset on the current line.
I wish to capitalize the first letter of a sentence, on-the-fly, as the user types the text in a CKEditor content instance.
The strategy consists in catching each keystroke and try to replace it when necessary, that is for instance, when the inserted character follows a dot and a space. I'm fine with catching the event, but can't find a way to parse characters surrounding the caret position:
var instance = CKEDITOR.instances.htmlarea
instance.document.getBody().on('keyup', function(event) {
console.log(event);
// Would like to parse here from the event object...
event.data.preventDefault();
});
Any help would be much appreciated including a strategy alternative.
You should use keydown event (close to what you proposed):
var editor = CKEDITOR.instances.editor1;
editor.document.getBody().on('keydown', function(event) {
if (event.data.getKeystroke() === 65 /*a*/ && isFirstLetter()) {
// insert 'A' instead of 'a'
editor.insertText('A');
event.data.preventDefault();
}
});
Now - how should isFirstLetter() look like?
You have to start from editor.getSelection().getRanges() to get caret position.
You're interested only in the first range from the collection.
To extract text content from before the caret use small trick:
move start of the range to the beginning of document: range.setStartAt( editor.document.getBody(), CKEDITOR.POSITION_AFTER_START ),
use CKEDITOR.dom.walker to traverse through DOM tree in source order,
collect text nodes and find out what's before caret (is it /\. $/) - remember that you have to skip inline tags and stop on block tags - hint: return false from guard function to stop traversing.
Example of how you can use walker on range:
var range, walker, node;
range = editor.getSelection().getRanges()[0];
range.setStartAt(editor.document.getBody(), CKEDITOR.POSITION_AFTER_START);
walker = new CKEDITOR.dom.walker(range);
walker.guard = function(node) {
console.log(node);
};
while (node = walker.previous()) {}
And now few sad things.
We assumed that selection is empty when you type - that doesn't have to be true. When selection is not collapsed (empty) then you'll have to manually remove its content before calling insertText. You can use range#deleteContents to do this.
But this is not all - after deleting range's content you have to place caret in correct position - this isn't trivial. Basically you can use range#select (on the range after deleteContents), but in some cases it can place caret in incorrect place - like between paragraphs. Fixing this is... is not doable without deeeeeeeep knowledge about HTML+editables+insertions+other things :).
This solution is not complete - you have to handle paste event, deleting content (one can delete words from the start of sentence), etc, etc.
I guess there are couple of other problems I didn't even thought about :P.
So this approach isn't realistic. If you still want to implement this feature I think that you should set timer and by traversing DOM (you can use walker on range containing entire document, or recently typed text (hard to find out where it is)) find all sentences starting from lower letter and fix them.
This is what worked for me in Ckeditor 4.
var editor = CKEDITOR.instances.editor1;
editor.document.getBody().on('keydown', function(event) {
if (event.data.getKeystroke() >= 65 && event.data.getKeystroke()<=91 && encodeURI(this.getText())=="%0A" && this.getText().length==1 ) {
//uppercase the char
editor.insertText(String.fromCharCode(event.data.getKeystroke()));
event.data.preventDefault();
}
});
var scin = new Scintilla();
ScintillaHotspotStyle = scin.Styles.LastPredefined.Index + 1;
scin.Margins[0].Width = 20;
scin.Caret.HighlightCurrentLine = true;
scin.Styles[ScintillaHotspotStyle].IsHotspot = true;
scin.Styles[ScintillaHotspotStyle].Underline = true;
scin.Styles[ScintillaHotspotStyle].ForeColor = System.Drawing.Color.Blue;
var contents = File.ReadAllText(file);
scin.Text = contents;
//scin.ConfigurationManager.Language = "cpp";
//scin.ConfigurationManager.Configure();
scin.GetRange(2, 5).SetStyle(ScintillaHotspotStyle);
//scin.ConfigurationManager.Language = "cpp";
//scin.ConfigurationManager.Configure();
It doesn't matter which order of the commented lines, nor if the call to .Configure() is performed - the outcome is the same:
If however, I do not apply the syntax highlighting, it does work:
Scintilla is pretty confusing, so I'm probably doing something wrong - but I'm not sure what...
I think that the syntax hiliting is applied after your job.
Or like if you read the scintilla documentation it seems than hotspot style have restricted feature.
"""
Caret, selection, and hotspot styles
The selection is shown by changing the foreground and/or background colours. If one of these is not set then that attribute is not changed for the selection. The default is to show the selection by changing the background to light gray and leaving the foreground the same as when it was not selected. When there is no selection, the current insertion point is marked by the text caret. This is a vertical line that is normally blinking on and off to attract the users attention.
"""
Did you try to force the style hiliting in an area which are not syntactically hilited ?
Near main or print as an example.
And try it by setting a background color.
