import statements |
----------------- |
Put imports at the top, unless there is a good reason otherwise. |
PEP 8 says to group stdlib, 3rd-party dependencies, and package imports. |
For idlelib, the groups are general stdlib, tkinter, and idlelib. |
Sort modules within each group, except that tkinter.ttk follows tkinter. |
Sort 'from idlelib import mod1' and 'from idlelib.mod2 import object' |
together by module, ignoring within module objects. |
Put 'import __main__' after other idlelib imports. |
Imports only needed for testing are put not at the top but in an |
htest function def or "if __name__ == '__main__'" clause. |
Within module imports like "from idlelib.mod import class" may cause |
circular imports to deadlock. Even without this, circular imports may |
require at least one of the imports to be delayed until a function call. |
What's New entries |
------------------ |
Repository directory Doc/whatsnew/ has a file 3.n.rst for each 3.n |
Python version. For the first entry in each file, add subsection |
'IDLE and idlelib', in alphabetical position, to the 'Improved Modules' |
section. For the rest of cpython, entries to 3.(n+1).rst begin with |
the release of 3.n.0b1. For IDLE, entries for features backported from |
'main' to '3.n' during its beta period do not got in 3.(n+1).rst. The |
latter usually gets its first entry during the 3.n.0 candidate period |
or after the 3.n.0 release. |
When, as per PEP 434, feature changes are backported, entries are placed |
in the 3.n.rst file *in the main branch* for each Python version n that |
gets the backport. (Note: the format of entries have varied between |
versions.) Add a line "New in 3.n maintenance releases." before the |
first back-ported feature after 3.n.0 is released. Since each older |
version file gets a different number of backports, it is easiest to |
make a separate PR for each file and label it with the backports |
needed. |
Github repository and issues |
---------------------------- |
The CPython repository is https://github.com/python/cpython. The |
IDLE Issues listing is https://github.com/orgs/python/projects/31. |
The main classification is by Topic, based on the IDLE menu. View the |
topics list by clicking the [<]] button in the upper right. |
Original IDLE todo, much of it now outdated: |
============================================ |
TO DO: |
- improve debugger: |
- manage breakpoints globally, allow bp deletion, tbreak, cbreak etc. |
- real object browser |
- help on how to use it (a simple help button will do wonders) |
- performance? (updates of large sets of locals are slow) |
- better integration of "debug module" |
- debugger should be global resource (attached to flist, not to shell) |
- fix the stupid bug where you need to step twice |
- display class name in stack viewer entries for methods |
- suppress tracing through IDLE internals (e.g. print) DONE |
- add a button to suppress through a specific module or class or method |
- more object inspection to stack viewer, e.g. to view all array items |
- insert the initial current directory into sys.path DONE |
- default directory attribute for each window instead of only for windows |
that have an associated filename |
- command expansion from keywords, module contents, other buffers, etc. |
- "Recent documents" menu item DONE |
- Filter region command |
- Optional horizontal scroll bar |
- more Emacsisms: |
- ^K should cut to buffer |
- M-[, M-] to move by paragraphs |
- incremental search? |
- search should indicate wrap-around in some way |
- restructure state sensitive code to avoid testing flags all the time |
- persistent user state (e.g. window and cursor positions, bindings) |
- make backups when saving |
- check file mtimes at various points |
- Pluggable interface with RCS/CVS/Perforce/Clearcase |
- better help? |
- don't open second class browser on same module (nor second path browser) |
- unify class and path browsers |
- Need to define a standard way whereby one can determine one is running |
inside IDLE (needed for Tk mainloop, also handy for $PYTHONSTARTUP) |
- Add more utility methods for use by extensions (a la get_selection) |
- Way to run command in totally separate interpreter (fork+os.system?) DONE |
- Way to find definition of fully-qualified name: |
In other words, select "UserDict.UserDict", hit some magic key and |
it loads up UserDict.py and finds the first def or class for UserDict. |
- need a way to force colorization on/off |
- need a way to force auto-indent on/off |
Details: |
- ^O (on Unix -- open-line) should honor autoindent |
- after paste, show end of pasted text |
- on Windows, should turn short filename to long filename (not only in argv!) |
(shouldn't this be done -- or undone -- by ntpath.normpath?) |
- new autoindent after colon even indents when the colon is in a comment! |
- sometimes forward slashes in pathname remain |
- sometimes star in window name remains in Windows menu |
