evil-mode in terminal without Alt/Meta

Thu, 12 Sep 2024 00:00:00 +0200

This morning I found the following post on reddit /r/emacs: Evil mode on a vt100 and I recalled having the same issue with terminal Emacs in xterm. By default, xterm emulates VT102, and behaving like VT100, will not send Alt/Meta key to Emacs without this workaround.In short, the workaround to send M-x in evil-mode even if Alt/Meta doesn't work is to use this combo: \ Esc-x. \ will temporarily suspend evil-mode and Esc-x is the same as M-x. The same will work with C-u M-x: type \ C-u Esc-x.I wasn't satisfied with this, we are using Emacs, after all ;) How about we can call M-x directly as evil-mode ex command? Sure, run this:

Faster man pages rendering

Thu, 01 Dec 2022 00:00:00 +0100

If you try to open rclone or gcc man pages with Emacs, you'd be surprised how unpleasant that experience can be. Those pages are over 30K lines and Emacs will became unresponsive easily. For how long will depend on your CPU.To speed up things, setting Man-fontify-manpage-flag to nil can alleviate this problem - it will disable highlighting of a man page and buffer can be somehow usable. Surprisingly, running woman, an alternative man pager written in elisp, will render the rclone man page faster, but it will leave a lot of garbage around.The fastest option for me was running a shell command man | col -b and reading that output directly as plain text in the Emacs buffer.

Edit files in (remote) Docker containers

Tue, 12 Jan 2021 00:00:00 +0100

I always had problems remembering Docker commands: to run a shell in a container, should I use docker run or docker exec? Wait, I probably need to "attach" the terminal to the running container. No problem, let's try docker attach. Ooops...These commands initially made no much sense to me - run and exec sounds like an alias to me and attach; well, Docker authors clearly had the idea that attaching to container and attaching shell input (typing commands inside container shell) are entirely unrelated things.Because of this, I kept personal docker.org file with all the notes how I'm going to start a container, run something in it, and so on.

Open (un)compressed file in Emacs

Sun, 26 Apr 2020 00:00:00 +0200

In Emacs, when you open a compressed file like foo.txt.gz, it will transparently decompress it (using gzip in the case above) and open as a regular file. However, what will happen if the above file is not compressed at all?Here is my case. I'm using excellent rclone to open remote S3 drives by mounting them in the local folder. From there, Emacs and dired works much better than any TRAMP hack I tried.However, an application that would ship logs to S3, would ship them with gzip extension attached (hence foo.txt.gz), but files would not be compressed. I'm not sure if this behavior is intentional or bug in the script, but this will cause Emacs to fail with this error:

Handle Chromium & Firefox sessions with org-mode

Wed, 04 Dec 2019 00:00:00 +0100

I was big fan of Session Manager, small addon for Chrome and Chromium that will save all open tabs, assign the name to session and, when is needed, restore it.Very useful, especially if you are like me, switching between multiple "mind sessions" during the day - research, development or maybe news reading. Or simply, you'd like to remember workflow (and tabs) you had few days ago.After I decided to ditch all extensions from Chromium except uBlock Origin, it was time to look for alternative. My main goal was it to be browser agnostic and session links had to be stored in text file, so I can enjoy all the goodies of plain text file. What would be better for that than good old org-mode ;)

ido-mode with eshell, shell, sql and more...

Wed, 07 Aug 2019 00:00:00 +0200

ido-mode doesn't provide completion for eshell, shell or sql-mode out of the box, and I wasn't been able to find any package with this option that is lightweight enough (Helm, I'm looking at you). So, after few attempts, here is the code for that:After evaluating the code, in eshell simply execute M-x ido-eshell-comint-history and magic will happen - you will get full eshell history managed by ido-mode. To make it more authentic, map it to C-c C-l, which is default sequence for completion in eshell.

declutter - read online content without clutter

Tue, 12 Jun 2018 00:00:00 +0200

Last two days I've been hacking on a small Emacs mode called declutter and this will be the first version announcement.What is declutter and why?I often use Emacs to read long, online articles, which gives me plenty of options - I can save text for offline reading, I can read content with my favorite color and terminal setup, I have my shortcuts for fast navigation and so on.

Emacs, git, gpg and 'failed to sign the data'

Tue, 03 Apr 2018 00:00:00 +0200

I'm not sure is this (un)common case, but when I used git with signing commits from Emacs with VC or Magit, I was getting this:Curiously, many had similar problem, but not from Emacs which is my case. On other hand, git signing from terminal worked without any problems for me.

Extending org-mode Easy Templates

Fri, 02 Mar 2018 00:00:00 +0100

I frequently use org-mode Easy Templates and I noticed I often miss shortcut for comment block (BEGIN_COMMENT/END_COMMENT) which is very useful from time to time.Let's add that feature.

Distraction-free EWW surfing

Fri, 01 Dec 2017 00:00:00 +0100

Sometimes when I plan to read a longish html text, I fire up EWW, a small web browser that comes with Emacs.However, reading pages on larger monitor doesn't provide good experience, at least not for me. Here is an example:

Closing all parentheses at once

Thu, 19 Oct 2017 00:00:00 +0200

While watching interesting presentation called Inspiring a future Clojure editor with forgotten Lisp UX, I've noticed author mentioned one really cool feature I was looking for some time - Interlisp's super-paren.In short, Interlisp had this unique super-paren option, bound to ] key, that would close all opened parentheses at once.To my knowledge, Emacs doesn't have something like this out of the box, unless you use Allegro CL mode or SLIME, but let's see how would it be hard to implement it.

Displaying org-mode appointments in calendar

Thu, 16 Feb 2017 00:00:00 +0100

One neat feature of org-mode agenda is ability to display appointments in Emacs calendar. Sadly, this isn't obvious nor enabled by default - I discovered it accidentally by browsing through Emacs themes screenshots.In screenshot below, you can see highlighted days with planned meetings and scheduled work in my calendar.

Literate programming with Monroe and org-mode

Wed, 21 Sep 2016 00:00:00 +0200

I'm starting to like literate programming with org-mode more and more, so I decided to try it in a small Clojure project. I'm aware of Marginalia, but since I'm planning to mix Clojure code with shell scripts and draw some charts, Marginalia won't be much of a help here.By default, org-mode does not have support for Monroe as REPL backend, and with some elisp bending, we are going to add it.The Code

Collapsing all filter groups in ibuffer

Sat, 18 Jun 2016 00:00:00 +0200

If you have to cope with large number of buffers, ibuffer is the only way to keep things manageable. It has support for filtering, sorting and, my favorite, grouping, which is indispensable when you are switching often between various projects and file groups like I do.However, one thing I always missed is ability to collapse all groups at once - a handy functionality when you have 10-30 groups and you'd not like to be distracted with not important buffers at that point.Is short, I want from this:

Unique buffer names in Emacs

Mon, 09 May 2016 00:00:00 +0200

When I work on large codebase done by more than one developer, I often find this pattern:Of course, this isn't the case with Java or Clojure only; this can be found in almost any larger project no matter what language is used. After all, folders are invented to keep the files under different namespaces, right?

Notmuch and Addressbook handling

Fri, 25 Dec 2015 00:00:00 +0100

I always had a problem with managing my email contacts, not because I'm lazy, but because tooling for that was/is really crude. In most cases (actually, in all cases AFAIK) I'd have to do it manually, by marking target address so the mail client knows what to store or do the hard work, open addressbook editor and fill necessary details.For example, in Mutt (which I used before) I'd have to press 'a' on desired address to be added on Mutt alias list. In Thunderbird, it is a totally different story: there are two contact lists - one you manually manage and the other is populated by Thunderbird by reading your recipient list.The problem with all of these approaches is that I'd have to think in advance if a particular email address is important for me, so I can do appropriate steps and save it. Of course, Thunderbird's Collected addresses can help here, but will not work unless you send an email.

evil-mode and xml folding

Wed, 21 Oct 2015 00:00:00 +0200

Recently I went back to Maven's pom.xml editing and still can't get that nice warm feeling with Eclipse. Yet.So, I was thinking, why not fire up Emacs (with evil-mode of course) and reuse all that folding goodness we get out of the box.The thing is, Emacs does not support xml folding out of the box, but thanks to this awesome tip from Jordon Biondo, you can easily add it. Here is a little bit improved version:

Emacs as default file manager in EDE

Tue, 15 Sep 2015 00:00:00 +0200

Just stumbled on this really neat post on how to setup Emacs as default file manager in Ubuntu. So, why we don't do the same in EDE?First create a script named dired and save it in known place, e.g. your $HOME folder, with this content (I found it here):
