I’ve encountered this rather profane yet tricky problem while testing a method: class MyClass : def __method (self) -> str: pass def test () with patch . object(MyClass, "__method" ) as _: pass pytest E AttributeError: <class 'MyClass'> does not have the attribute '__method' A llm pointed to the name mangling cause. Changing __method to _MyClass__method fixes the error: def test () with…
I found this code 1 to display the wireless status in the modeline. A first attempt led to nothing i.e. nothing was shown in my modeline. I had to modify the regex in order to match the output of /proc/net/wireless : diff --git a/wireless.el b/wireless.el index 55ec7fc..e08f864 100644 --- a/wireless.el +++ b/wireless.el @@ -55,7 +55,7 @@ :group 'wireless) (defcustom wireless-procfile-regexp - "^[…

For starters, you want to write brother in ancient greek. Type adelfos to get an understanding of what’s happening. Set the input method to greek-babel: M-x set-input-method greek-babel . 1 Type adelfos again. The last typing of “adelfos” results in αδελφοσ. So far so good. However, αδελφοσ is wrong. It should be ἀδελφός. To be specific, we’re missing diacritics on a…
I’m testing a script against a live database. Accessing the db is slow and the test iterates trough all rows each time. Since I’m gradually increasing rows on each test run, I need only some, but not all rows. Problem: How can I avoid loading all rows but only fetch some ? Solution : Use yield Takeaway: Memorize the word yield as alias for fetch some. Why words matter is beautifully…
Emacs provides an incredible python developer experience. One of it many features is the ability to run pytest. However, I spent a reasonable amount of time, figuring out why M-x python-test-one was ignoring my pytest log level settings in pyproject.toml . Whatever I set in pyproject.toml, M-x python-test-one was printing out any level e.g. logger.INFO("do not show in test") pyproject.toml [tool .…

Links in Emacs org mode allow arbitrary emacs-lisp execution. As a result, we can run any shell command, such as your favorite movie player : [[ elisp:(async-shell-command "mplayer /tmp/lecture.mp4") ][ linktitle ]] Arguments work too. e.g. play the movie from a particular position. This can come in handy when learning materials contain valuable information scattered throughout movies: [[…
I’m quite fond of keeping my code formatted. For example I use yapf to format python code. Sometimes I want particular regions not to be formatted . In particular I want rows to stay rows but one line. The solution is to indicate such regions for the formatter Without indication, the buffer is formatted from this: rows = [ ( 'john' , 'acme' ), ( 'jane' , 'acme' ) ] to that: rows = [( 'john'…

Given your image-dired tags have similar beginnings e.g 0.jpg;foo 1.jpg;foo: Now all you enter – in order to mark – images tagged with foo but not foo: , is this: M-x image-dired-mark-tagged-files foo$ Note the dollar sign suffix Why is such profane regex noteworthy? See how image-dired-dired.el preliminary establishes the tag collection: "\\(^[^;\n]+\\);\\(.*\\)"
