’ which in turn expands to ‘z’. ’ here is nested within the outer variable reference. The previous example shows two levels of nesting, but any number of levels is possible. ’, which becomes ‘u’. References to recursively-expanded variables within a variable name are re-expanded in the usual fashion. ’ which becomes ‘Hello’. Nested variable references can also contain modified references and function invocations (see Functions for Transforming Text), just like any other reference. ’, a simple variable reference whose value is ‘Hello’. A computed variable name need not consist entirely of a single variable reference. It can contain several variable references, as well as some invariant text. ‘a.c b.c c.c’ or ‘1.c 2.c 3.c’, depending on the value of a1. The only restriction on this sort of use of nested variable references is that they cannot specify part of the name of a function to be called. This is because the test for a recognized function name is done before the expansion of nested references.
It is requested, but not required, that you contact the authors of the Document well before redistributing any large number of copies, to give them a chance to provide you with an updated version of the Document. 5. MODIFICATIONS You may copy and distribute a Modified Version of the Document under the conditions of sections 2 and 3 above, provided that you release the Modified Version under precisely this License, with the Modified Version filling the role of the Document, thus licensing distribution and modification of the Modified Version to whoever possesses a copy of it. 1. Use in the Title Page (and on the covers, if any) a title distinct from that of the Document, and from those of previous versions (which should, if there were any, be listed in the History section of the Document). You may use the same title as a previous version if the original publisher of that version gives permission.
There are four different directives that test different conditions. Expand all variable references in arg1 and arg2 and compare them. If they are identical, the text-if-true is effective; otherwise, the text-if-false, if any, is effective. Often you want to test if a variable has a non-empty value. When the value results from complex expansions of variables and functions, expansions you would consider empty may actually contain whitespace characters and thus are not seen as empty. However, you can use the strip function (see Functions for String Substitution and Analysis) to avoid interpreting whitespace as a non-empty value. Expand all variable references in arg1 and arg2 and compare them. If they are different, the text-if-true is effective; otherwise, the text-if-false, if any, is effective. The ifdef form takes the name of a variable as its argument, not a reference to a variable. If the value of that variable has a non-empty value, the text-if-true is effective; otherwise, the text-if-false, if any, is effective.
See The Two Flavors of Variables. After all variables are thus bound, text is expanded to provide the result of the let function. When first called, let will expand $1 to d c b a. It will then assign first to d and assign rest to c b a. The recursive invocation of let assigns first to c and rest to b a. The recursion continues until let is called with just a single value, a. After the reverse call is complete, the first and rest variables are no longer set. If variables by those names existed beforehand, they are not affected by the expansion of the reverse macro. The foreach function is similar to the let function, but very different from other functions. It causes one piece of text to be used repeatedly, each time with a different substitution performed on it. The foreach function resembles the for command in the shell sh and the foreach command in the C-shell csh.
You are likely summarizing a full book or an article or short story, which will be much longer than 3-4 pages. Imagine that you are the author of the work, and your editor comes to you and says they love what you wrote, but they need it to be 3-4 pages instead. How would you tell that story (argument, idea, etc.) in that length without losing the heart or intent behind it? That is what belongs in a summary paper. How Do I Write Useful Academic Notes? Sometimes, you need to write a summary for yourself in the form of notes or for your classmates in the form of a discussion post. You might not think you need a specific approach for this. After all, only you are going to see it. However, summarizing for yourself can sometimes be the most difficult type of summary. If you try to write down everything your teacher says, your hand will cramp and you’ll likely miss a lot.
