Description kde49534 2012-11-08 19:20:16 UTC

The maximum length I can set the title of the window to is 74 characters, and the first 74 characters at that. This is not good when it's showing the current full directory path (%w) and I'm in a deep tree. I think it should be allowed to expand to the maximum size of the whole title bar, and start replacing the leftmost characters with an ellipsis if it goes bigger than that.

Note this is not the tab title, but the window title.

Reproducible: Always

Steps to Reproduce:
1. Enter a deep tree: cd /tmp/1234567890/1234567890/1234567890/1234567890/1234567890/1234567890
2. Observe the window title: "kdeuser@localhost:/tmp/1234567890/1234567890/1234567890/1234567890/1234567"
3. Change to another deeply rooted directory: cd ../foo
Actual Results:  
Observe the window title: "kdeuser@localhost:/tmp/1234567890/1234567890/1234567890/1234567890/1234567"

Expected Results:  
Window title: "kdeuser@localhost:/tmp/1234567890/1234567890/1234567890/1234567890/1234567890/foo"

Some names have been changed to protect the innocent.

Odd. It works here exactly as you want it, eliding text with "..." in the middle.

In 2.8.5? Using %w? This attachment shows what I see…

Comment 4 Christoph Feck 2012-11-08 22:50:00 UTC

I am on master, and used %D to show full path.

%w indeed seems to cut, less than 50 characters here. That's probably simply a copy of the Tab text copied to the window title, but it should be the other way around...

Comment 5 Kurt Hindenburg 2012-11-09 03:26:31 UTC

It appears the max token is 80 so the text received for %w will always be less

Vt102Emulation.h:#define MAX_TOKEN_LENGTH 80

This code is quite old - I'll have to try to figure out why that's there.

Increase length of tokens

Currently, the max length of a token is 80.  This affects the window
title causing the max length of around 74.  The main usage is to allow
a really long window title.
>From what I gather xterm doesn't have a limit.  If needed, this #
could be increased.

FIXED-IN: 4.10
