[screen-devel] [Patch] Add support for Alt + Key

[masterenoc]

Hi All,

I have been hacking Gnu Screen to add support for alt keys, and it may

add some value to Screen, please check the attached patch and let me

know what you think. Notice that the patch was based on the v.4.9.0

tag, but it should work in the master branch since the modified files

have not been touched in years.

The patch adds support for Alt keys with '@' notation, the '@' will be

the textual representation of Alt within the bind, escape, defescape

and markkeys commands; the patch also adds some comments and changes

the name of some variables within src/process.c file.

I tested the changes manually, since I did not find any test suite,

but it was not an exhaustive test since I am using only a small subset

of Screen capabilities; nevertheless, the changes seems to be self-contained

within the logic of the commands and process.c, which, at least for

me, makes it harder to add bugs outside of the commands logic.

I found some discrepancies in the coding style, some files use K&R

C (src/process.c) code and other file use ISO C; Some files use

Gnu C code style while other files disregard this Gnu code style. In

case my patch gets accepted please let me know if I should modify the

C style of the modified files.

Best regards,

Bryan Hernández
