Patching TERMINFO¶
Introduction¶
When using the native (NCURSES) ChUI client, some default TERMINFO definitions are broken. The vt320, vt220 and xterm definitions need to be fixed. This document details how to fix the TERMINFO definitions.
Manually Patching¶
Follow the next 3 steps to update the definitions (the example only shows vt320 case) manually.
Decompile the TERMINFO Entry¶
Use this command:
infocmp vt320 > vt320.tmp
The result will be saved in the temporary file.
Edit and Fix the Definitions¶
Edit the temp file vt320.tmp. Notice the TERMINFO location mentioned in the first line. It is typically: /usr/share/terminfo/v/vt320. Apply the specific changes documented here:
| Definition | xterm | vt220 | vt320 |
|---|---|---|---|
| TAB | n/a | n/a | ensure that ht=^I, exists and that knxt=^I, is deleted |
| HOME | n/a | n/a | add or modify the khome= to be khome=\EOH. |
| END | n/a | add or modify the kend= to be kend=\E[F | add or modify the kend= to be kend=\EOF |
| BACKSPACE | add or modify kbs= to be kbs=\177 | n/a | n/a |
| cursor visibility | n/a | add or modify the civis= to be civis=\E[?25l add or modify the cnorm= to be cnorm=\E[?25h |
n/a |
Save the file.
Recompile the TERMINFO Entry¶
Use the following command to compile the definition:
sudo tic -o/usr/share/terminfo vt320.tmp
Automating the Patching Process¶
Please see Automating the Patching Process for a solution.
The same patch_terminfo.sh script in the automated process can be ran manually, too:
wget https://proj.goldencode.com/attachments/download/5745/patch_terminfo.sh chmod +x patch_terminfo.sh sudo ./patch_terminfo.sh
