best way to edit lines in ymacs?

[Joe]

I found how to get the line of the mark:
var mr = this.markMarker.getRowCol().row;

So now what is the best way to edit lines? for example, if I want to
go though a group of lines and apply substr() or replace() on them.

I tried:
// no workie
this.code[i] = this.code[i].replace(regex,"");

// works, but it seems to get ymacs confused:
this._replaceLine(i,this.code[i].substr(toremove));
or
this._replaceLine(i,this.code[i].replace(regex,""));;

thanks,

Indeed, _replaceLine should not be used directly.. The way to go is
via insert and delete commands. Either:

this.cmd("delete_region", begin, end);
this.cmd("goto_char", position_for_insertion);
this.cmd("insert", text_to_insert);

Or the more direct (these should be public API in fact):

this._deleteText(begin, end);
this._insertText(text_to_insert, position_for_insertion);
this._replaceText(begin, end, replacement_text);

It's pretty awkward to use these for line-by-line changes, but you can
do this instead:

var text = this._bufferSubstring(begin, end);
var new_text = do_something_on(text);
this._replaceText(begin, end, new_text);

HTH.
