Doom 64 Passwords Switch

[Marybelle Bailey]

Inmy ongoing series of literate config files, I am now posting my Doom Emacs config. I switched to Doom from my hand-crafted Emacs config some time ago, and I have been really enjoying it. Hope you find it useful!

This file is written in literate programming style using org-mode. See init.el, packages.el and config.el for the generated files. You can see this in a nicer format on my blog post My Doom Emacs configuration, with commentary.

Note: a lot of manual configuration has been rendered moot by using Emacs Doom, which aggregates a well-maintained and organized collection of common configuration settings for performance optimization, package management, commonly used packages (e.g. Org) and much more.

All the config files are generated from this Org file, to try and make its meaning as clear as possible. All package! declarations are written to packages.el, all other LISP code is written to config.el.

We start by simply defining the standard headers used by the three files. These headers come from the initial files generated by doom install, and contain either some Emacs-LISP relevant indicators like lexical-binding, or instructions about the contents of the file.

Allow mixed fonts in a buffer. This is particularly useful for Org mode, so I can mix source and prose blocks in the same document. I also manually enable solaire-mode in Org mode as a workaround for font scaling not working properly.

I love the spacemacs-light theme, but for some reason, the transparent dashboard images showed up with a light tint, which I eventually tracked to the fact that Doom by default uses the font-lock-comment-face for the dashboard banner image, and this this face has a background color in Spacemacs-light. I redefine the doom-dashboard-banner face to use the default face, which fixes the problem. Another way to fix it (commented out below) is to disable the background tint color in the theme. While we are at it, I also fix doom-dashboard-loaded, which suffers from the same problem.

Doom Emacs has an extensive keybinding system, and most module functions are already bound. I modify some keybindings for simplicity of to match the muscle memory I have from my previous Emacs configuration.

Note: I do not use VI-style keybindings (which are the default for Doom) because I have decades of muscle memory with Emacs-style keybindings. You may need to adjust these if you want to use them.

Use counsel-buffer-or-recentf for C-x b. I like being able to see all recently opened files, instead of just the current ones. This makes it possible to use C-x b almost as a replacement for C-c C-f, for files that I edit often. Similarly, for switching between non-file buffers I use counsel-switch-buffer, mapped to C-x C-b.

The counsel-buffer-or-recentf function by default shows duplicated entries because it does not abbreviate the paths of the open buffers. The function below fixes this, I have submitted this change to the counsel library ( -abo/swiper/pull/2687), in the meantime I define it here and integrate it via advice-add.

The switch-buffer-functions package allows us to update the recentf buffer list as we switch between them, so that the list produced by counsel-buffer-or-recentf is shown in the order the buffers have been visited, rather than in the order they were opened. Thanks to @tau3000 for the tip.

One of the few things I missed in Emacs from vi was the % key, which jumps to the parenthesis, bracket or brace which matches the one below the cursor. This function implements this functionality, bound to the same key. Inspired by NavigatingParentheses, but modified to use smartparens instead of the default commands, and to work on brackets and braces.

Org mode has become my primary tool for writing, blogging, coding, presentations and more. I am duly impressed. I have been a fan of the idea of literate programming for many years, and I have tried other tools before (most notably noweb, which I used during grad school for homeworks and projects), but Org is the first tool I have encountered which makes it practical. Here are some of the resources I have found useful in learning it:

Enable Speed Keys, which allows quick single-key commands when the cursor is placed on a heading. Usually the cursor needs to be at the beginning of a headline line, but defining it with this function makes them active on any of the asterisks at the beginning of the line.

counsel-org-link uses org-id as its backend which generates IDs using UUIDs, and it uses the ID property to store them. I prefer using human-readable IDs stored in the CUSTOM_ID property of each heading, so we need to make some changes.

Second, I override counsel-org-link-action, which is the function that actually generates and inserts the link, with a custom function that computes and inserts human-readable CUSTOM_ID links. This is supported by a few auxiliary functions for generating and storing the CUSTOM_ID.

I use LeanPub for self-publishing my books. Fortunately, it is possible to export from org-mode to both LeanPub-flavored Markdown and Markua, so I can use Org for writing the text and simply export it in the correct format and structure needed by Leanpub.

ox-hugo is an awesome way to blog from org-mode. It makes it possible for posts in org-mode format to be kept separate, and it generates the Markdown files for Hugo. Hugo supports org files, but using ox-hugo has multiple advantages:

This function receives three arguments, and returns the org-mode code for a link to the Hammerspoon API documentation for the link module, optionally to a specific function. If desc is passed, it is used as the display text, otherwise section.function is used.

The first function is a modified version of the org-num--number-region function of the org-num package, but modified to only return the numbering of the innermost headline in which the cursor is currently placed.

Tangle-on-save has revolutionized my literate programming workflow. It automatically runs org-babel-tangle upon saving any org-mode buffer, which means the resulting files will be automatically kept up to date. For a while I did this by manually adding org-babel-tangle to the after-save hook in Org mode, but now I use the org-auto-tangle package, which does this asynchronously and selectively for each Org file where it is desired.

Some useful settings for LISP coding - smartparens-strict-mode to enforce parenthesis to match. I map M-( to enclose the next expression as in paredit using a custom function. Prefix argument can be used to indicate how many expressions to enclose instead of just 1. E.g. C-u 3 M-( will enclose the next 3 sexps.

I use 750words.com for recording some writing every day (1464-day streak as of this writing!). I wrote 750words-client to allow posting my words from the command line, and the code below integrates this into Emacs, so I can post text directly from the current buffer.

So I've fallen foul of the recent security changes and accessing my old NTLWorld email. I had access to it on my phone via generating an app password, however since signing out (via browser) I'm unable to get back in.

Obviously there is the old....forgot password route but that just prompts you to enter the email you use to login to your virgin media account, which then only resets the password for the @virginmedia.com email address and not the NTLworld one.

So at the moment I'm lost in a forever loop of doom trying to find a way in. Can't seemingly add or switch to my NTLworld account / email once logged into the virgin account and unable to change the password or set a new app password for the NTL account.

Each VM email address including Ntlworld have a distinct My Virgin Media account. So when you use the forgotten password route you need to use the Ntlworld email address not the virginmedia email address.

I'm a Very Insightful Person, I'm here to share knowledge, I don't work for Virgin Media, I'm a VM customer. There are no guarantees that my advice will work. Please read the FAQs

Thanks for the reply, although I've tried logging into my account using the NTLWorld email (as I've done in the past) but my password doesn't work, probably because I had to change it for the security update and I can't remember what it is.

I then try to change the password and I just get prompted with "Please ensure you provide the email address you use to sign in to My Virgin Media." and it doesn't allow me to reset the ntlworld password, although I can the virginmedia one.

Anyway the upshot is, although I've been accessing my account(s) the same way since day dot it seems everything has changed.......and now to get to my ntlworld email I have to log in via an account linked to a gmail address, which I've never used to access anything (although I was asked to provide a backup email at some point).

So to get access I log in via my gmail virginmedia hub account and then get into my email.....so I have access again.....BUT I was told by the virgin tech that NTLWorld accounts are no longer accessible via 3rd party apps, so I have to go in via a browser.

This completely confounds me, especially seeing as the tech said this has been the case for quite some time. Despite having a previous (recent) email saying I needed to set an app password for this email account to access it.
