Features
A formatter that deletes the control characters contained in an open document. The control characters to be deleted by default are as follows:
/[\u0000]|[\u0001]|[\u0002]|[\u0003]|[\u0004]|[\u0005]|[\u0006]|[\u0007]|[\u0008]|[\u000b]|[\u000c]|[\u000d]|[\u000e]|[\u000f]|[\u0010]|[\u0011]|[\u0012]|[\u0013]|[\u0014]|[\u0015]|[\u0016]|[\u0017]|[\u0018]|[\u0019]|[\u001a]|[\u001b]|[\u001c]|[\u001d]|[\u001e]|[\u001f]|[\u001c]|[\u007f]/gm
It is also possible to define the regular expression pattern as a user.
This extenstion was created to cope with the problem that the backspace control character in the Issue below:
How to use
Install extensions,
- Execute the
Format Document command,
- If
"editor.formatOnSave": true is set, invoke on save (⌘S)
- If
"editor.formatOnType": true is set, invoked on Enter (line break) or ; input
In either case, the action is triggered and the control character is deleted.
Manual execution
The Format Document command and editor.formatOnSave, editor.formatOnType will trigger all formatter defined with * FormattingEditProvide.
Therefore, if you want to use them as a single function without using them, please use the Remove control characters command.
User defined
If there is a problem with the default control character, you can customize it using the ctrlchar-remover.pattern setting.
Delete the character that matches the pattern of the specified regular expression. (If you specify \u0008, you must escape with\, like \\u0008)
ctrlchar-remover.pattern:
Example deletion of backspace (\u0008) only:
"ctrlchar-remover.pattern": "[\\u0008]"
Example of deletion of backspace (\u0008) and Line Feed (\u000a):
"ctrlchar-remover.pattern": "[\\u0008]|[\\u000a]"
ATTENTION: Of course, you can also specify patterns other than control characters.
Tips
- Can be visualized by
Toggle Control Characters command or View -> control character switching.
- To handle with the basic function of VS Code without using this extension, input
[\b] for search by typing ⌥⌘F and using .* (⌥⌘R), To search backspaces control character in the document. In addition, you can delete it by pressing Replace All (⌥⌘Enter).
- if
afterDelay is set as the value of files.autoSave, the format will not be applied during auto save.
Control character reference
References
This extension is applied to all language modes because language mode is not specified.
If you want to enable it only in a specific language mode, enclosing it with "[language-mode]":{} enables it only for the specified language-mode.
Below is an example that applies only to Markdown mode:
"[markdown]": {
"editor.wordWrap": "on",
"editor.quickSuggestions": false,
"editor.formatOnSave": true,
"editor.formatOnType": true
}
In order for formatOnType to work, it is necessary to input a trigger character.
Yes - format on type only works on certain trigger characters. Extension define what those characters are, for instance TypeScript uses \n, ;, and }.
