I notice that the current auto-mode-alist entries all end with a single quote, for example ("\\.java\\'" . java-mode) What is the purpose of the single quote. I would have expected to see ("\\.java$" . java-mode) The reason I ask is that I am trying to get files with names matching regexp ^twiki\.corp.* to open in org-mode. I have tried the following without success: (add-to-list 'auto-mode-alist '("^twiki\\.corp" . org-mode)) (add-to-list 'auto-mode-alist '("\\'twiki\\.corp" . org-mode)) The following works: (add-to-list 'auto-mode-alist '("twiki\\.corp" . org-mode)) but is not quite what I

Say if I have the following: func(arg1, arg2, arg3...) func(longargarg1, longerarg2, arg3,...) ... How do I align the arguments so that it's like following? func(arg1 , arg2 , arg3...) func(longargarg1, longerarg2, arg3,...) ... [I can use M-x align-regex to align the first argument, but I cannot cook up with a suitable regex to align the rest of the arguments. Bonus point if the answer also take cares of the case when some arguments are strings with commas in them.] Select the region, then: C-u M-x align-regexp RET ,\(\s-*\) RET RET RET y The regexp says to align commas with spaces following

I use ansi-term for my normal terminal sessions. I tend to use unicode characters in my prompt to do things like set the trailing character based on the type of source control I'm using. I use the character "±" as my prompt for git repositories. In Emacs' ansi-term, my prompt isn't rendered as unicode, and shows as "\302\261". Displaying the current coding system shows that it defaults to utf-8-unix for input to the process, but I get raw binary as the decoding output. I can hit C-c RET p to change the encoding and decoding coding systems. I'm drawing a blank as to how to set this

Is there a way to periodically run an elisp function in a long-running emacs, similar to cron, but within the emacs process? For example I want to "automatically run (recentf-save-list) every half hour" because it otherwise only runs on exit, which sucks when emacs occasionally crashes. (There are other examples as well so looking for a general solution rather than one in particular for recentf). Check out run-with-timer . (run-with-timer 0 (* 30 60) 'recentf-save-list) You might also find midnight mode useful. One can arbitrarily define 'midnight' and then add hooks as desired. 来源： https:/

Org-mode has a bundled extension called org-id , that implements global unique IDs for org-mode files. Every entry (a headline with its body) can have an ID property in its :PROPERTIES: drawer. New ID for a single entry can be assigned with a function org-id-get-create . How can I assign an ID to every entry in an org-mode file? I could use an Emacs method of automating this, like a macro that calls org-id-get-create for every string starting with * . But I'd like to know if org-mode already has that capability. If not, please recommend the most idiomatic way to write an elisp code for this

I'm looking for a solution that allows me to write native Emacs Lisp code and at compile time turns it into HTML, like Franz's htmlgen : (html ((:div class "post") (:h1 "Title") (:p "Hello, World!"))) Of course I can write my own macros , but I'm interested if there are any projects around this problem. Trey Jackson As you found out , xmlgen generates XML from a list structure. What I did find disappointing with the ``xmlgen` package that the format it supports is not quite the inverse of Emacs' xml parser . I did add this to my copy of xmlgen: ;; this creates a routine to be the inverse of

Imagine I've got the following in a text file opened under Emacs: some 34 word 30 another 38 thing 59 to 39 say 10 here 47 and I want to turn into this, adding 1 to every number made of 2 digits: some 35 word 31 another 39 thing 60 to 40 say 11 here 48 (this is a short example, my actual need is on a much bigger list, not my call) How can I do this from Emacs? I don't mind calling some external Perl/sed/whatever magic as long as the call is made directly from Emacs and operates only on the marked region I want. How would you automate this from Emacs? I think the answer I'm thinking of consist
