问题 While playing with Erlang getting started section I have met bizarre syntax error on trivial use case (simple map initialization). Are there any suggestion why does that happen? 1> #{ "key" => 42}. 1: syntax error before: '{' Details: Erlang R16B03 (erts-5.10.4), Eshell V5.10.4. 回答1: Because maps were introduced in Erlang 17. You have to upgrade your installation or do not use maps. 来源： https://stackoverflow.com/questions/31589190/why-do-i-get-syntax-error-before

问题 I want to run Node.js in eshell, but the prompt does not right: So, how can I fix this? 回答1: Try running node in eshell with NODE_NO_READLINE enabled. For example, you could add an alias to eshell by running this command in eshell: alias node 'NODE_NO_READLINE=1 node' 回答2: An alternative is to add this to your .emacs: (setenv "NODE_NO_READLINE" "1") The benefit of this approach is that it will also work for other invocations of Node programs that you run directly. 来源： https://stackoverflow

Compiling Programs from Within Emacs?

问题 What is the best way to compile programs inside emacs? I am currently opening a separate buffer with C-x 3 and running eshell inside it using M-x eshell then invoking either make or clang directly; most of the time I do have a Makefile set up. Is there any advantage with running the compilation process using M-x compile vs running make inside eshell? Any other ways to do it and what are the advantages/disadvantages of those? 回答1: The easiest way to do this is to use the Emacs built-in compile

What setup file does eshell (elisp shell) read when it starts? How eshell sets its PATH?

问题 With emacs/eshell, the "echo $PATH" shows different paths than that of $PATH environment variable. And I also checked that eshell doesn't read .bashrc or .profile, and I think that's the reason why the path is different. What setup file does eshell read when it starts? How eshell sets its PATH? How to make the eshell's PATH the same as the environment variable's PATH? ADDED As Jérôme Radix pointed out, the PATH depends on how I start the Aquamcs. When I click the button to start Aquamacs, it
