Support the use of environment variables for settings

[Joebeazelman]

It's common for a debugging target to reference settings stored in environment variables such as its GDB toolchain path. While such values can be manually evaluated and entered in Seer's settings, it would save a lot of effort if it supported environment variables directly.

Hi,

I'm not clear yet with your request. Can you give a couple real examples of the environment variables you are talking about.

THanks.

[Joebeazelman]

Basically, it would be nice to enter environment variables such as $(GDB_PATH) into the configuration dialog fields.

Hi,

To confirm, to allow environment variables when specifying the path to the gdb executable. Something like this?

There are some paths in the "Source" tab that can benefit as well. I suspect, though, that you're suggesting any field might benefit from environment variables.

If a $XXXX something can't be expanded, there should be an error dialog.

I think this is all do-able.

[Joebeazelman]

Exactly! This would be excellent, since some tools have special toolpaths.

I just pushed a change to the "main" branch that you can clone. I've only added support for environment variables for the name of the gdb program and to the gdb arguments.

For example, if I set these environment variables:

$ export GDBHOME=/usr/bin
$ export GDBMI='mi'
$ seergdb -s myprog one two three

The config dialog can work with:

I support both ways of expanding environment variables.

${HOME}
$HOME

But not this way. I've only seen that in Makefile. Unless its a MacOS thing.

$(HOME)

Anyway, clone the latest, when you are able, and let me know what you think.

Thanks.

I mentioned this in another issue, but I'll repeat it here. The configuration dialog doesn't save the settings. Typing it over is a bit tedious.

[epasveer]

After changing the settings, you can save the settings with "Settings -> Save Configuration".

I did it this way because you may want to debug something with the new settings to try out. If the new settings work, they can be saved. If not, they can be forgotten just by quitting out of Seer.

Hi Joe. Can this task be closed?

[Joebeazelman]

Yes.

Thanks. Closing task.
