so-long mode makes buffer read only. To erase the content we need to make buffer editable.

Activate so-long-mode instead of fundamental-mode for log files: it is faster! https://www.reddit.com/r/emacs/comments/rcgjpt/browsing_long_lines_are_extremely_slow_i_study/

Disabled log4-hi-func-keywords function & prettify-symbols-mode to improve performance when navigating long lines in log files.

Fixed typo.

Use "find -exec" with "+" to avoid excessive grep forking.

Added more Sabre attributes for highlighting.

More parrterns for SSR.

Fixed highlighting of some Sabre XML tags when they are without XML namespace.

Fix for dired in TRAMP.

Fix for dired in TRAMP: in Cygwin I rely on external ls by setting ls-lisp-use-insert-directory-program to "t" (so Emacs won't crash when access P9 mounted WSL paths). Seems some switches broke TRAMP.

Highlighting for Sabre SSRs.

Added highlighting of SSR's FullText.

emmet might be absent when we activate it in web-mode-hook.

Increased GC threshold. Fixed unbalanced parentheses.

Updated Sabre XML entries to highlight.

Updated Sabre XML entries to highlight.

Helper functions for Sabre GDS.

Add some standard places to PATH if they are not set by login script. Rearrange the order of paths so system's are first, user's are last. For Cygwin this helps with Cygwin's paths to be situated before "C:/Windows" (Emacs is not started from a login shell on Windows!).

csv-mode requires for setting to be set via defcstom only...

Add some standard places to PATH as Emacs is not started from login shell on Windows...

Added mode for recognition of Windows paths in Cygwin Emacs.

Separated Cygwin & ansi colors settings.

Repeating my-calc-line interactive place result after "=" sign clearing any old text.

Show only the matching closing parenthesis, flashing entire expression is irritating.

Marked some Python related variables / values as safe for being local.

Defined key bindings to some project search/replace functions.

Added binding for project-find-file.

Reserved s-= for my-calc-line (to avoid excessive typing of M-x my-calc-line). er/expand-region is now s-w to be near C-w/M-w.

hs-toggle-hiding has bug in v27.1. I eliminated "(event-end e)" from "hs-toggle-hiding" as workaround.

tags-completion-at-point-function over python-completion-at-point as latter doesn't work for me in Cygwin.

Fixed: Symbol's value as variable is void: my-profiler-enabled.

Defined page-delimiter for my elisp file to simplify narrowing. As I migrated to Markdown define fill-column for base mode.

Docs: about buffer-menu vs ibuffer.

Removed mentioning of author and copyright from all files' headers.

Moved definition of root for Org mode files to defs file.

Docs: Legacy setup instructions for native Windows Emacs.

Converted README to Markdown format.

Docs: my-profiler-enabled.

Moved Gnus's all.SCORE to separate project as it reveals some private data.

Grouped startup profiler related code with debug related.

Activate debugger of errors during Emacs initialization. This allows to get backtrace without passing --debug-init.

Moved settings for file local variable to a separate section.

Docs: improved comment.

It is more informative to get help on symbol type than just type.

Unwrap Python's dir() list into multi line text.

Added other types of introspection to my-python/describe-at-point.

Activate outline-minor-mode for markdown-mode. And avoid whitespace-mode.

Shortened name for pydoc buffer.

Fixed my-python/send-paragraph: part of region was remained highlighted after (mark-paragraph).

Simplified code for displaying Python help. Shadow default C-c C-d key binding with enhanced implementation. Fixed hanging of Python process during initial loading (due to extra code put into python-shell-setup-codes).

Set better rename detection (30% similarity) for Git diff.

Mentioned python-shell-interpreter-args.

Do not sent my outdated my-python/eldoc-setup-code to Python interpreter.

Added example how to activate babel executors.

Enabled org-tempo for shortcut to insert template #+BEGIN_SRC quickly.

About term-paste.

Added note about winner-mode.

Moved setting for backups, auto saving, locking earlier. This keeps policy the same for modes saving state into files. Otherwise you'll see files like ".recentf~" in "~/.emacs.d".

Disable auto saving, files "#name#" might trigger false rebuild if there is some file watcher. Also those files looks like garbage in other tools/IDE.
