Chapter 5. 1.10 Getting Help. So now you know what you’ll be looking at. Don’t be intimidated by the wealth of searches that are available. In practice, you’ll probably settle on one search command and one replace command and use these for 99 percent of your work. For example, we use incremental search and query-replace most of the time. If you’re a writer, you may use word search all the time; if you’re a programmer, you might want a regular expression search. If you’re just beginning, you may want to learn incremental search and read the rest of this chapter later. However, if you know what’s available, you’ll be able to make use of the other search commands when they become useful.. It’s easy to create buffers, and just as easy to delete them when you want to. You may want to delete buffers if you feel your Emacs session is getting cluttered with too many buffers. Perhaps you started out working on a set of five buffers and now want to do something with another five. Getting rid of the first set of buffers makes it a bit easier to keep things straight. Deleting a buffer can also be a useful emergency escape. For example, some replacement operation may have had disastrous results. You can kill the buffer and choose not to save the changes, then read the file again.. 5.5.1 Displaying the Calendar. psgml mode consists of two parts: sgml-mode for writing SGML and xml-mode for writing XML (and in our case XHTML).. The following is an example of whatC-M-\ does. This example is in C, and subsequent examples refer to it. The concepts in all examples in this section are applicable to most other languages; we cover analogous Lisp and Java features in the sections on modes for those languages.. /* This is a comment paragraph with wildly differing right margins.. The functionsmatch-beginning andmatch-end can be used to retrieve the saved portions of the matched string. Each takes as an argument the number of the matched expression (as in\\n inreplace-regexp replace strings) and returns the character position in the buffer that marks the beginning (formatch-beginning) or end (formatch-end) of the matched string. With the argument0, the character position that marks the beginning/end of the entire string matched by the regular expression is returned.. Is replaced by the Java package which contains the file being created (assuming the file is a Java class). This package is determined by examining the directory structure in which the file is being placed.. %tar xvf texinfo-4.7.tar. %which emacs. Search the index for a topic..
