Emacs: Change IPython traceback background color from yellow to black

Readul Hasan Chayan [Heemayl] — Tue, 14 Jan 2025 14:18:03 GMT

I use elpy minor-mode for my local Python development work and it works great for me. Quickly dropping into a ipython shell after evaluating the current buffer or a particular region (using elpy-shell-send-region-or-buffer) is a great way to play around without even needing to invoke a debugger as the local and global namespaces are readily available there. There's a very nagging issue with ipython though

Emacs: Buffer-switch indicator

Most of the time, I have many windows open in Emacs, so it really helps to have an indicator of the current window (and buffer) especially when switching between windows.

Emacs: Managing Python virtual environments

Readul Hasan Chayan [Heemayl] — Wed, 17 Jul 2024 15:07:40 GMT

elpy is a great minor-mode for python-mode (major-mode) in Emacs, but managing multiple venvs (virtual environments) has always been tricky as pyvenv (that elpy uses) doesn't have a way to have buffer-local venv (virtual environment) -- any venv activated using e.g. pyvenv-activate/pyvenv-workon is (process) global.

Emacs: Auto-format strings to a max column width in `python-mode`

Readul Hasan Chayan [Heemayl] — Fri, 28 Jun 2024 16:05:22 GMT

I use blacken-mode (uses black) to auto-format Python code on save -- it works great but not much helpful while dealing with strings. For example, if I want to set a max limit on columns (characters) per line when writing a string, black is of no help. So I needed to come up with something in emacs that does the auto-format of strings -- set a max limit on-the-fly on number of columns per line for writing strings.

Emacs: Dynamic buffer-local fringes

Readul Hasan Chayan [Heemayl] — Sun, 23 Jun 2024 08:31:48 GMT

Emacs has a global fringe-mode for fringes, which I always keep disabled as it takes a bit of space in the frame and I like to start typing the first character on a line to the very left. But there are some cases where fringes are quite useful e.g. when flycheck shows different checker warnings/errors in code, it uses fringes (if enabled) to have a nice arrow to indicate the line(s) with the warnings/errors -- great to have a quick glance at everything.

Emacs recipe for starting tensorboard server

Readul Hasan Chayan [Heemayl] — Mon, 19 Dec 2022 11:04:50 GMT

tensorboard is a quite popular among deep learning practitioners for experiment tracking. I also use it often, but what was bothering me for a while was to start the server (using tensorboard command) on one emacs buffer every time I want to track something. It gets tedious very quickly considering restarts as well. So, I've written a tiny elisp recipe to start/restart tensorboard directly from the (Python) file buffer (python-mode) in emacs.

Emacs: Invoke search engine on browser with search term

Readul Hasan Chayan [Heemayl] — Thu, 08 Sep 2022 08:49:15 GMT

As I do most of my daily works on emacs, it's the only program always running on my system. So from time to time I try to create small recipes to make my life easier while using it.

Recently I thought of an idea to invoke the search engine on browser with search term directly from emacs; so essentially I don't want to go to browser and search for a term, it will do that for me.
