When we use Emacs Org to take a lot of notes and write a lot of experience, we will certainly want to publish them as websites. By posting notes to a Web page, we can easily share our experiences with others. In general, there are three common methods: First, you can use the built-in page publishing function of Org to publish a static webpage (or view this document ). Second, if we need more complex and A

Implement GTD using Org-mode With the powerful task management function of Org-mode, combined with other Emacs plug-ins, you can easily implement personal time management (GTD ). If you do not know about GTD, you can have a preliminary understanding of GTD within two minutes.Table of Contents 1. How to perform GTD 1.1 Collection 1.2 sorting 1.3 organizations 1.4 Review 1.5 execution

List module for columns in Perl, and list module for perl tools There are some modules specifically used in Perl to Process List data, such as List: Util module. This module is included in the standard library and provides various efficient common List processing tools. Because it is implemented in C language, the speed is generally quite fast!

Here we will summarize the issues that need to be paid attention to when programming in the Perl language. 1. the hash value is not sequential, so the values returned by the hash function are all sort, rather than the status when the hash value is assigned. For example: my %hash2=( ‘ten‘ => 10, ‘fiirt‘ => 1, ‘second‘ => 2, ‘third‘ => 3, ‘fouth‘ => 4);print keys %hash2;---result-----fiirtsecondthirdfouthten Using the hash function each, the result is a

The best way to correlate cross-information is to label it. The org mode of Emacs is very powerful in supporting tags.Each title can contain a list of tags at the end. Labels consist of letters, numbers, ' _ ' and ' @ '. There must be a colon before and after the label, such as ': work: ' . You can also declare multiple tags like ': work:urgent: ' . The label is bold by default and has the same color as the title. You can specify a different style for

Perl language learning notes 9 Regular Expressions for text processing, perl Language Learning 1. Replacement S/PATTERN/REPLACE/; # returns the Boolean value of whether the replacement is successful. You can use capture variables, such as s/(\ w)/$1/ If the matching fails, no processing is performed. 2. delimiters For delimiters without left or right, repeat them three times, for example, s //, s ### There

Perl is a very flexible scripting language. There is also a demand scenario for reflection. Reflection is the conversion of a string to the corresponding language object. (Do not consider the ultimate kill technique such as eval) 1. Reflection as a normal variable this is not supported, that is, you can not achieve My $a = "B"; My $b = "123"; Print \ $a; # trying to get "123" is impossible.The alternative is to use hash My $b = ' 123 '; My $c {' B '}=

Method 1: Maven is used to build an application in the past two days, there are more than 700 pom. XML file, even more depressing is in many pom. the URL of the resource library is specified separately in the XML file. I need to uniformly specify the URLs of these resource libraries to the local central nexus library. it is not practical to manually change the file configurations one by one, So Google will find a good way to replace the file content in batches. The command structure is as
