![]() Finally, the last command is used to jump back up in the tag stack to the location you initiated the previous tag search from. If there are multiple definitions/uses for a particular tag, the tn and tp commands can be used to scroll through them, and the ts command can be used to "search" a list for the definition you want (useful when there are dozens or hundreds of definitions for some commonly-used struct). The second command can be used to search for any tag, regardless of the file that is currently opened. The first command is probably the one you will use most often: it jumps to the definition of the tag (function name, structure name, variable name, or pretty much anything) under the cursor. List all of the definitions of the last tag Go to the previous definition for the last tag Go to the next definition for the last tag Or, open any Linux source file in Vim and use the following basic commands: Importantly, Jaikoz only replaces cover art with higher quality artwork and unlike iTunes the images are added directly into your files so they are always available whatever music player you are using. To search for a specific tag and open Vim to its definition, run the following command in your shell: When matching with Musicbrainz or Discogs, Jaikoz usually finds album artwork and adds it to your music files. You may see messages like "Warning: cannot open source file '.' : Permission denied" while ctags is building the tags file. This specific spot is hidden from the vast majority of mp3 id3 tag editors though. To switch back to your original buffer and expand it, use C-x o to switch to it, then C-x 1 to expand. When you're done, instead of jumping back up in the tag stack, close the new buffer ( C-x k). Switch to the new buffer ( C-x o), scroll through the list of definitions to the one that you want, then press Enter to open the file. This will display a list of the tag definitions in another buffer. In this case, you can run the following two commands to list all of the uses of a given : You'll probably find that for some tags (common structures, for example), Etags finds hundreds or thousands of uses in the code, and jumping through them (with the third command above) to try to find the original definition is useless. Finally, use the fourth command to jump back up in the tag "stack." Sometimes Etags will find multiple definitions for a given tag when this is the case, use the third command to jump through the possible definitions until you find the one that you want. The second command can be used to search for any tag in the TAGS file, regardless of the file you are currently viewing. The first command is probably the one you will use most often: it jumps to the definition of the tag (function name, structure name, variable name, or pretty much anything). Say yes when prompted to load the really big tags file. If that's what happened here, you need to learn to spot BS3 code so you can ignore it and look elsewhere.The first time you run an Etags command within Emacs, you may have to specify the location of your TAGS file (i.e. But people keep copying and pasting old BS3 code into blog posts and Stack Overflow answers, so other people keep getting surprised that the code they found online doesn't actually work. Which shouldn't even need to be mentioned, as BS3 has been dead for nearly a decade, and doesn't run on Python 3.x or, in some cases, even 2.7. Notice that CSS also doesn't care about the order of the classes, or about duplicates: > lect('span.c.a.b.c')Īlso, this allows you to search for a subset of the classes, rather than just one or all of them: > lect('span.c.b')ġ. Or, maybe you don't want to think in DOM terms but in CSS-selector terms: > lect('span.a.b.c') ![]() Notice that, even though BeautifulSoup is presenting the values as a list, they actually act more like a set-you can pass the same values in any order, and duplicates are ignored: > soup.find('span', class_=): To search for a multi-valued attribute, you should pass multiple values: > soup.find('span', class_=('a', 'b', 'c')) > soup = BeautifulSoup(text, 'html.parser') The class attribute isn't a normal string, but a multi-valued attribute.
