Time Narration
00:00 Welcome to this spoken tutorial on Report Writing using LaTeX.
00:06 Notice three windows in the screen: source file is in the editor. I am using Emacs editor.
00:14 In the terminal, I compile the source file and create a pdf file. I view this pdf file in the pdf reader.
00:23 I am using a pdf reader called “skim” on Mac OS X. This reader loads the latest version of the pdf file.
00:33 When you create your documents using Latex, you need not arrange these windows in such a non-overlapping fashion.
00:41 You may also use a different editor and a different pdf reader.
00:48 The procedure to use latex is identical in all Unix systems including Linux.
00:53 It could be a little bit different on Windows. Nevertheless, the source file is identical in all operating systems.
01:01 As a result, your working LaTeX source file on windows, for example, will work without any change on Unix systems as well.
01:11 The first spoken tutorial in this series is on compiling. Which gives a brief introduction to Latex.
01:19 You may want to go through it in case you have not done that already.
01:23 I am using 12pt as the text size and article class.
01:30 I have defined titles of section, sub-section and sub-sub -section.
01:36 The argument of each of these appears in the output at appropriate places.
01:44 Observe the distinctive feature of these section titles.
01:49 Irrespective of blank lines in the source file, the output remains the same.
01:55 Let me add some blank lines here.
02:00 Save. Compile. No difference.
02:08 Put the source file back to the original state. Compile.
02:20 The sizes of the titles are created proportionately and automatically. For example, the section title is the largest and the sub-sub-section title is the smallest.
02:32 These features remain the same even if I change the font size.
02:36 Let’s change it to 11pt. Save. Compile.
02:46 Although the overall size decreases, the above mentioned qualities of the titles do not change.
02:52 Let me change the font back to 12pt.
03:03 A more important feature of the titles is the automatic generation of section numbers. For example, if I insert another section here,
03:25 save. Compile.
03:30 I will create a new section in the output called ‘Inserted section’. It appears here with appropriate number.
03:39 In summary, the spacing, size, and distinctiveness, that is, the titles appear in bold etc. are automatically taken care of by Latex.
03:50 I will now explain how to create table of contents. First of all, note that there is no file called 'Report.toc'.
04:05 Here it says that there is ‘no such file or directory’. Observe that 'report.tec' is the source file.
04:12 Let me add this command, 'table of contents', one word, here. Save. Compile.
04:31 As I compile it, the word ‘Contents’ appears in the output but nothing else.
04:44 We now have a file called 'Report.toc'.
04:54 The section titles are written into this 'toc' file. Let’s see this.
05:05 Okay, let me recompile it.
05:12 Okay. All the titles are now present in the contents page along with page numbers.
05:18 Page number here is 1; it appears in the table of contents. This document has only one page.
05:23 This two time compilation procedure is applicable also to changes in titles.
05:33 Let us insert a new title here. Let me call it ‘Modified section’.
05:45 Let me compile it. You can see that it has changed here but it is yet to change in contents.
05:54 Let me re-compile it second time and solve this problem. We can also change the location of the table of contents.
06:02 Let me shift it to the end of the document. Compile it.
06:18 Now we can see that it has come to the end of the document. Let us bring the document back by shifting this to the top.
06:38 We will now create a title for this document.
06:44 Let me do it here, just after the document class. 'Author'.
07:03 I can include new lines here.
07:11 Date, today’s date. And then, ‘First created on 13th July 2007’. We compile it.
07:29 There are no changes. The reason is that I have not told latex what to do with this information.
07:35 So, I add the ‘make title’ command here, just after the document.
07:45 One word at the place where I want the title to appear
07:50 which is at the beginning of the document. On compiling, the title appears in the output.
07:58 We will now change the class of this document from 'article' to 'report'. So let's do that here. Let me compile it.
08:14 On compiling, the title appears on a whole page. The 'Contents' starts on a new page, with page 1. This is numbered as page 1.
08:33 In other words, the title page has no number. We also see the section title has a zero in its number.
08:44 The report class requires chapters. As we have not defined any chapters, the default value of zero is used.
08:52 The sub-sub section, no longer has a number associated with it.
09:01 The contents information is not correct, they still carry the old numbers.
09:07 We solve this problem by recompilation. Now we have the new numbers.
09:13 Let us start a chapter now.
09:25 ‘First chapter’ we call it. Let us compile it twice. The contents did not change but the other things are missing.
09:40 The reason is that the 'chapter' command starts a new page.
09:48 Let us go to the next page and confirm it.
09:52 See also the explicit appearance of the word ‘chapter’ on the new page.
09:58 See it here. Let me come back here.
10:04 Let me compile it. Once more you can see that the new chapter information comes in the contents.
10:14 If you want to add appendixes, insert the command ‘appendix’.
10:23 'Appendix' and let me start a chapter in the appendix.
10:37 ‘First chapter in the appendix’. Let me compile it twice.
10:47 You can see that the first chapter has come here.
10:51 Let’s go and see what it looks like.
11:00 Appendix A has moved to a new page.
11:05 And you can see the number of pages as gone to 4.
11:10 And you also have this word ‘appendix’ appearing here. Let us add one more chapter. Let me compile it.
11:27 You can see the page number has become 5. It is on a new page. Let us go the beginning of this.
11:38 If I compile it second time, the contents become correct.
11:49 What happens if we want to change the 'report' class back to 'article'?
11:53 We go here. Let's compile it.
12:09 On compiling, the latex complains that there is something wrong.
12:19 Okay, there are two ways to handle when latex stops like this.
12:24 The first way is to exit by typing ‘X’.
12:32 The pdf file will normally have all the previous pages. In this particular case it says that there are no pages of output.
12:40 One can immediately go to the source file, modify the problems and proceed.
12:48 It is easy to locate the errors if the beginner compiles frequently;
12:56 any mistake will be caught immediately. Sometimes when latex pauses because of mistakes, I end the document then and there.
13:06 Of course, also close all the open environments and try to locate and fix the mistake.
13:12 As latex does not worry about the material that comes after the 'end document' command, no need to change that part.
13:20 Once the error is corrected, the intermediate ‘end document’ command under close environment commands can be removed.
13:28 When latex pauses sighting an error, we can also ask it to ignore and to proceed.
13:44 This is done by pressing the Return or Enter key
13:48 as I did just now. Now what happens is, we have two pages.
13:59 Go to the first page, we have all messed up information.
14:07 What we can do to correct this mistake is – the mistake is that it is having the chapter here.
14:16 Let us remove this.
14:22 Let’s compile it. Okay, let’s do it again. Let’s compile it second time.
14:33 It complains, keeps complaining but there is something called chapter and it is in the table of contents and in the appendix.
14:47 So, let us get rid of this also. Let's compile it.
14:56 Okay. Now it goes through without any problem and the entire document has come in one page.
15:05 And the content information also is correct.
15:15 Feel free to change the source file, for example- you may want to add new sections, new sub-sections in the main text and also in the appendix, also in the report style.
15:26 Try out the commands explained in this tutorial; until you become confident, keep trying.
15:34 Ensure that your recent changes are acceptable by immediate compilation after every change.
15:40 Most beginners who forget this rule, get into a lot of difficulties.
15:45 Please note that the way the source file appears in Emacs – color, size of titles etc. are immaterial as far as the latex engine is concerned.
15:57 What Latex wants is that the source file be correct and not how it is created.
16:04 This brings us to the end of this tutorial. Thanks for joining. This is Kannan Moudgalya from CDEEP, IIT Bombay, signing off. Good bye.
