1/11/2024 0 Comments Search emacs![]() As time has shown, however, once you learn the basics, you have a powerful, efficient, and extremely hackable editor for life. Users love Emacs because it features efficient commands for common but complex actions and for the plugins and configuration hacks that have developed around it for nearly 40 years.īecause it's an old editor that was developed well before modern computer conventions and terminology existed (for instance, you "visit" instead of "opening" a file, and you "write" instead of "save," and so on), Emacs is often viewed as complex and even mysterious. Welcome to the communityĮmacs is a text editor designed for POSIX operating systems and available on Linux, BSD, macOS, Windows, and more.With Icicles, command icicle-occur (bound to C-c ') lets you search within lines as search contexts. That is much more limited that, say, searching within whole function definitions, which is what I think you are asking for. ![]() Other answers here that mention occur and similar ( helm-occur) provide a limited kind of context searching: the search contexts are just the lines of a buffer. Searching zones of text that have given text or overlay properties, i.e., ignoring other text. Strings, comments, XML elements.), i.e., ignoring other text outside the THINGs. Searching the text of different kinds of THINGs (e.g., sexps, sentences, lists, You can alternatively use a function to define the search contexts. Command icicle-search prompts you for the search context-defining regexp. The simplest way is by providing a regexp. To search only non-interactive function definitions, use command icicle-imenu-non-interactive-function-full.īeyond searching definitions, you can easily define any kind of contexts to be searched. To search only command definitions, you can use command icicle-imenu-command-full. These are collectively called Icicles Imenu commands. Icicles has several predefined Icicles search commands for searching definitions like this. In Lisp, this would be things like defuns. What you are asking for (if I understand correctly), is to search only within certain search contexts.įor example, as in this case, you might want to search only within function definitions - the search contexts are function definitions. If you use library Icicles then you can easily do this kind of thing. In either of these modes, selecting the match in the occur buffer and pressing enter will jump you to that line in the code. SPC foo to narrow the results to lines also containing foo.function to show all lines containing "function".M-x helm-occur RET to open a Helm Occur window.In Helm you can search for multiple search terms just by separating them with a space. In this case, the *Helm Occur* buffer will not be directly searchable with C-s. If you have helm installed you can use helm-occur to do something similar. C-s to start a search within the search results.C-x o to move focus to the *Occur* buffer.M-s o function RET to show all lines matching "function".The resulting *Occur* buffer is searchable using isearch ( C-s). Occur will prompt you for a regexp to search for, and then it will open a new window showing all of the lines in the current buffer that contain a match. The occur command is part of vanilla emacs, and is bound to M-s o by default. If you have Helm installed, then you can use helm-occur instead. Emacs has a command called occur that is very well suited to this type of task.
