[Pydev-code] Has the analyze only open editors setting ever had a meaning?

[Andreas P. <an...@fr...>]

Hi,

I recently stumbled about the 'Builder' page and its 'Analyze only open 
editors' setting. It sounded like disabling this would help one of our 
customers who wanted to get completion for functions in modules that are not 
yet imported. Unfortunately it turns out this preference is not being used 
anywhere in the codebase and looking at the existing pydev tags has never 
been used.

I'm wondering wether I'm missing something or wether this has really been 
added (to the ui) and then never used (by the builder)?

On a related note: Is there a way to get pydev to create completions for 
functions/classes in files that haven't been opened yet (after starting 
eclipse)? (i.e. where do I have to look into the codebase to find the 
starting point)

Actually, that's still used... if you take a look at the code, the getter
which uses the ANALYZE_ONLY_ACTIVE_EDITOR constant is
org.python.pydev.builder.PyDevBuilderPrefPage.getAnalyzeOnlyActiveEditor().

What it does is that if it's unchecked, we'll analyze all the files in the
workspace when they're changed (by the pydev builder) and not only if
there's an editor open for that file (so, usually it's not recommended as
it can be a resource hog, but if you do have CPU/RAM to spare, it's still
an option).

As for getting completions for functions/classes that haven't been
imported, I think I don't quite follow what you mean (you do have
context-insensitive code-completion which would add the import and the
token -- but apparently, that's not what you meant), so, can you rephrase
that to explain better your use case?

Cheers,

Fabio

Re-reading I'm not sure I was clear on the analyze files... what I meant
was that we do code-analysis on files that haven't been opened in an editor
(the indexing is done for all files regardless of that setting -- so, if
the file is under the PYTHONPATH, it should always be indexed and kept up
to date with a builder).

Cheers,

Fabio

Ah, I missed the public static getter and its uses during my grep :)

What I see happening is that completion does not include functions from 
modules that haven't been open in an editor. For example lets take this 
project:

myproject
  |
  - module1
  |    |
  |    - util.py
  |
  - module2
       |
       - main.py

util.py has just 1 function definition 'mycoolfun' and main.py is empty. 
After a fresh start of Eclipse I open main.py and type myc and invoke 
code-completion. There's no entry for mycoolfunc. If I open util.py, close it 
again and again invoke code-completion inside main.py the entry for 
'mycoolfunc' shows up.

My assumption was that this is caused by the 'analyze-only-open-editors' 
setting, but changing the setting from its default value did not help.

Andreas

PS: The project's root folder is configured as python path so that shouldn't 
be a problem.
PPS: Tested this with the master branch as well as seeing it with the 2.8 
release.

Humm... that sounds like you have disabled auto-build (project > build
automatically)... if that's the case, you have to invoke the build manually
for pydev to index those files (Ctrl+B)... or maybe something else became
wrong and the indexing became lost (if that's the case, a manual fix would
be going to the project properties > pydev-pythonpath > force restore
internal info -- and it should definitely be kept up to date afterwards if
auto build is turned on).

Automatic project building is enabled, but indeed cleaning the project fixes 
the problem. At least until the next restart of Eclipse. It seems there's no 
rebuild happening immediately after starting Eclipse and hence the 
information for completion is not available.
