First of all, thanks for the patch.<br>
Please only sent patches, the full files are not needed (and quickly <br>
outdated in case of trunk).<br>
Ideally go to <a href="https://bugs.freepascal.org/" rel="noreferrer" target="_blank">https://bugs.freepascal.org/</a> register and submit your <br>
patch with a new issue. I can not always deal with patches immediately, <br>
and in my mail inbox they can get lost very quickly.<br>
Once you opened an issue, you can link to it, when you sent an email.<br>
<br>
<br>
Patches against trunk are the correct way.<br>
Other than getting trunk, there is no need to deal with svn or any <br>
revision management system.<br>
<br>
Besides the issues described below, your patch was very helpful, as it <br>
pointed me to the correct location for the fix. And it's review brought <br>
up more issues that need/needed fixing.<br>
<br>
------------------------------------<br>
About the patch itself.<br>
<br>
Both of the issues below, had been present before your patch. So they <br>
are not a result of your patch.<br>
I have fixed the first of the 2 issues, and committed this to trunk 2.1<br>
<br>
<br>
***1)<br>
If the text contains tabs, or special chars (such as umlauts äöü, <br>
accents, Japanese, Arabic, ....) then it can fail.<br>
<br>
X (in the search code) is a byte position into the string. It is not a <br>
position on the screen.<br>
<a href="https://wiki.lazarus.freepascal.org/SynEdit#Logical.2FPhysical_caret_position" rel="noreferrer" target="_blank">https://wiki.lazarus.freepascal.org/SynEdit#Logical.2FPhysical_caret_position</a><br>
<br>
Consider those Lines: . for spaces, \t shall be a tab, with tab-width = 4<br>
<br>
........ab cd ef gh // 8 spaces "cd" is at x=12<br>
ääääööööab cd ef gh // 8 umlauts (each 2 bytes) "cd" is at x=20<br>
\t\tab cd ef gh // 2 tabs (same width as spaces) "cd" is at x=6<br>
........ab cd ef gh // 8 spaces "cd" is at x=12<br>
<br>
However, the "cd" on each line are aligned on the screen. So you can <br>
have a column selection, that in each line has "cd ef g"<br>
If in that column selection you replace "ef" with "EF", then your <br>
ptStartX=12 and ptEndX=19 => will replace nothing in the 2 middle lines.<br>
<br>
<br>
***2)<br>
Further more, if the text to be replaced occurs twice on a line<br>
........ab cd cd ef gh<br>
and "cd" is replaced by "CB and more", then the 2nd "cd" may get pushed <br>
out of the range, before being replaced.<br>
<br>
This is not yet fixed.<br>
According to me test this is "compatible" with Delphi 10.3<br>
(I.e. it seems to be not working in Delphi too)<br>
