Several POSTGUI HAL files in .ini

Hi all,
I was trying to improve my linuxcnc project and was wondering if you can have several POSTGUI_HALFILE files

When I tried in the .ini file to do :
POSTGUI_HALFILE = postgui_module1.hal
POSTGUI_HALFILE = postgui_module2.hal
POSTGUI_HALFILE = postgui_module3.hal

only the postgui_module1.hal is actually loaded. I would like to split my POSTGUI in several files as it become bigger and bigger with the progress of my project. Would be nice to separate the POSTGUI in dedicated functioning part (for instance one motion related and one tool control related). Otherwise I guess I will have to call a POSTGUI_HALFILE = postgui_modules.hal and from postgui_modules.hal call the different files. Only issue, I am not sure about the command from a hal file to call another hal file when it is in the POSTGUI.

Thank you for your help,

Nicolas

In general, guis support a single POSTGUI_HALFILE.

A common work around:


from the halcmd man page:
Ref: linuxcnc.org/docs/devel/html/man/man1/halcmd.1.html

Hi, thanks for your answer.

I had a look to the man halcmd to find some elements for another quick question: can I split a command line into several line into a halcmd file?

Especially I tend to use more the loadrt with the names options, but it tends to finish with really long lines that I would like to split on different lines to make it easier to read.

Thank you,

Nicolas

No.

If you use twopass processing, you can use multiple short
loadrt lines in the same or multiple files. Example:
As mentioned here:

For readers,

The Postgui.hal file is a very important file, loaded at the end of all normal hal files.
It's really loaded at the end of loading all normal .hal files. So it's the last hal file to load. It's a special custom file to load.

The Postgui.hal file can have information about thing's that must be keep the same after updating linuxcnc.
The Posthui.hal file can not be made multiple times. Hal files can be made multiple times, Postgui.hal only once.

Multiple hal files for example : init.hal - servo.hal - inputs.hal - outputs.hal - gmoccappy.hal - gscreen.hal , etc. etc.

A real life example :

You have 1 machine with Gmocappy 3 installed just yesterday. Okey you sell this machine from Bosnie to Afganistan. The guy in afganistan does a linux update after a few month's, after typing the wrong thing, he does dis perhaps without knowing what he is doing.... or dist-upgrade or whatever he want's, even a new stepper configuration setup would not affect the installation files. Then the Postgui.hal file is not changed and he can be using the machine without calling you for any help.

Hi,
thanks dgarrett for your answer.

I have explored the name convention with two pass but the limitation to 16 item is actually annoying even though you can extend it thanks recompiling the required components.

Thank you,

Nicolas
