• 07:01 UTC (diff) (history) Comments on 2019-02-17 Inserting the current file name at point . . . . Marcin Borkowski – Thanks, that is nice! Are you aware that after saying {{{!}}} in Dired you can use {{{?}}} and {{{*}}} in the command?

• 07:08 UTC (new) (history) 2019-02-17 Inserting the current file name at point . . . . Marcin Borkowski – It is not uncommon to issue some command to Emacs and find oneself in the minibuffer with the need to insert the name of the current file. A typical example would be firing M-! (shell-command) and realizing that we need to gice the name of the currently visited file as the argument to some command.
• 07:02 UTC (diff) (history) Comments on 2019-02-10 Making recover-this-file messages more prominent . . . . Marcin Borkowski – Hi, and thanks! I corrected your formatting. Notice that your approach is going to show all the recover messages in {{{*Messages*}}} every time . . .

• 11:26 UTC (diff) (history) Comments on 2019-02-04 A simple template mechanism in Elisp . . . . Marcin Borkowski – Wow, thanks to both of you! I didn't know about either. {{{s-format}}} looks really nice, and its from Magnar Sveen, so it's good quality (and more . . .
• 08:21 UTC (new) (history) 2019-02-10 Making recover-this-file messages more prominent . . . . Marcin Borkowski – When I start my Emacs, I visit all my agenda files automatically (of course, I set up the org-agenda-files variable first). This has an annoying side effect.

• 04:46 UTC (new) (history) 2019-02-04 A simple template mechanism in Elisp . . . . Marcin Borkowski – A long time ago I asked on the Emacs mailing list about a templating mechanism for Emacs Lisp. Of course, there is format. However, I don’t like it as a template engine, since the entries are identified by their order and not names. Then, there is YASnippet and skeleton.el, but they are (probably) better suited for interactive use. (At least Yasnippet can be used programmatically, but it seemed to be too complicated for my needs anyway back then.) Some people suggested other solutions, none of which really appealed to me. So, I set out to write my own.

• 18:30 UTC (new) (history) 2019-01-28 A simple tip with killing and yanking code . . . . Marcin Borkowski – I often kill (cut) some code and then yank (paste) it somewhere else. Often the level of indentation is wrong in the new place (for instance, something is put from a higher level into a then-branch of a conditional).

• 19:47 UTC (new) (history) 2019-01-20 Filling and version control . . . . Marcin Borkowski – It has been said a lot of times that when writing some (natural language) text with version control in Emacs, filling is a bad idea. Any change involving adding or deleting a significant number of characters and then refilling can result in all subsequent lines in a paragraph changed, and the diff looks really ugly then. The solution usually proposed is putting each sentence on a separate line, and then just use visual-line-mode to wrap your lines on the screen without putting any hard newlines in. Well, I sort of dislike this idea.

• 05:23 UTC (new) (history) 2019-01-14 Some Org Agenda keybindings . . . . Marcin Borkowski – This post is just a friendly reminder that it may be a good idea to look in the manual from time to time, just in case there are some gems hidden there you don’t remember (even if you read it once). It turns out that you can do a lot of things from the Org Agenda buffer.

• 21:14 UTC (new) (history) 2019-01-06 Emacs server and other Emacs instances . . . . Marcin Borkowski – A few years ago, I mentioned indirectly that I use emacs-server. For some time, I just had (emacs-server) in my init.el. This, however, had an annoying side effect of giving an error when I started a second instance of Emacs.

• 08:26 UTC (new) (history) 2018-12-31 An info about the size of message attachments . . . . Marcin Borkowski – I have been using mu4e for quite a long time as my email client now. I would never switch back to Claws Mail again (maybe mutt, with emacsclient as the editor;-)). However, mu4e has some rough edges. One of them (which is really a problem with Emacs’ message-mode) is displaying of attachments when writing the message.

• 22:01 UTC (new) (history) 2018-12-24 Merry Christmas . . . . Marcin Borkowski – As usual at this time of year, I have best Christmas wishes for everyone reading this. I wish that you all discover the beauty and truth of the . . .

• 11:46 UTC (new) (history) 2018-12-16 A simple tip on using destructive functions . . . . Marcin Borkowski – This is something fairly obvious to every seasoned Lisp programmer, but let’s not forget that there are novices, too. Many Elisp functions are noted to be “destructive”, which means that they can change their arguments. For instance, if you want to sort a list, you may use the sort function, which is said to modify its argument by side effects (this is exactly what “destructive” means). This does not necessarily mean, however, that after executing (sort some-list), the variable some-list will magically contain a sorted version of it previous self! Let’s consider two examples.

• 05:00 UTC (new) (history) 2018-12-10 Lesser known Dired stuff . . . . Marcin Borkowski – It is not a secret that I am a big fan of Dired. Recently I learned about a thing introduced relatively recently into Emacs

• 08:46 UTC (new) (history) 2018-12-03 looking-back-p . . . . Marcin Borkowski – Emacs has a very useful function looking-at, which says whether the text from the point on matches a given regex. Unfortunately, it modifies the match data, which are global state referring to the last search. Because of that, I often prefer to use looking-at-p, which takes care not to mess with the match data.
• 08:42 UTC (diff) (history) Comments on 2018-11-19 Font-locking diff blocks in Org-mode . . . . Marcin Borkowski – Well, this is what my Emacs outputs when I use commands such as {{{dired-diff}}}, which is what I probably did, and then copied that to a src block.

• 16:56 UTC (new) (history) 2018-11-26 format-seconds . . . . Marcin Borkowski – If you’ve ever done anything UI- and time-related in Elisp (or whatever language), chances are that you did stuff like (defun format-minutes (minutes) "Format MINUTES in a human-friendly way."
