Latest build, latest Mac OSX.
I have a personal Latex_Piero.tmLanguage §i’d like to use for Latex.
If I switch syntax to it and save the file, it switches back to standard.
If I switch syntax via the menu View>Syntax>Open all with…
it switches back to standard.
If I create a Latex_Piero.sublime-settings file in my User directory containing
{“extensions”: [“tex”]}
it switches back to standard.
Any pointers to what might be wrong?
Thanks
Piero
Are you using a custom theme? Some theme authors override extension settings.
Do you have any custom LaTex packages installed?
Can you provide a link to your .tmLanguage file?
What does view.settings().get("syntax") in the console yield (with the view active that you are having trouble with)?
The command view.settings().get(“syntax”) gives Latex_Piero immediately
after I switch to my syntax, but after a save it gives Latex
The theme is Soda Dark, I made some minor customization in a sublime-theme
file inside my User dir.
As to my personal .tmLanguage, it is a bit of a mess, I have experimented a bit too much with it. If necessary I can send you a link
Latex packages installed: LatexTools. There is a Latexing cache but the package has been removed.
Inside my User dir there is a ton of plugins but until recently they gave me no problem. Should I look into them?
Ok so I took out all my customizations from the Latex_Piero.tmLanguage file
and the problem persists.
Here is a link to the reduced example

If I create a file starting with \documentclass{beamer} and
save it, the syntax is automatically set to Latex. If I manually
switch to Latex Beamer, then save again, the syntax
reverts to Latex. Is this the intended behaviour of the
default packages?
I don’t believe Latex_Piero.sublime-settings is going to be the correct name for the settings file since your syntax is named Latext.Piero. I may be incorrect about this, but I would try and see if Latex.Piero.sublime-settings works instead. Alternatively, perhaps giving your syntax a name without a . in it.
Yes, I noticed that and changed the name, without any improvement. But as I said, even if I remove completely my tmLanguage file, I have the same problem with the default packages Latex/Latex Beamer. If I select Latex Beamer as syntax (on a file starting with \documentclass{beamer} ), after a save the syntax switches back to Latex. Is this the expected behaviour?
This is strange, right? I will open a topic just to know if this behaviour is standard or not, hope this is not bad mailing list behaviour. In case let me know and I’ll remove the new topic
If you do create a related topic, it’s good behaviour to link to it, to make it easier for others to find in future if they have the same problem 
PROBLEM SOLVED (main cause stupidity as it is well known)
The Latextool package has a new setting to always save as Latex
