How to get the source code of the program. Do you really need the source code? How to view the source code of a page to debug a script

If you right-click the page text. You can also use the keyboard shortcut CTRL + U. Mozilla FireFox does not use external programs - the source code of the page with syntax highlighting will be opened in a separate browser window.

In Internet Explorer, click the File menu and select Edit in Notepad. Instead of the name Notepad, another name may be written, you have assigned it in the browser settings to view the source code. By right-clicking on a page, a context menu appears, which also has an item that allows you to open the source code of the page in an external program - “View HTML Code”.

In the Opera browser, open the menu, go to the “Page” section and you will have the opportunity to select the “Source Code” item or the “Frame Source Code” item in the “Development Tools” subsection. These selections are assigned the hotkeys CTRL + U and CTRL + SHIFT + U, respectively. The context menu associated with right-clicking a page also has a “Source Code” item. Opera opens the page source in an external program that is designated in the OS or browser settings for editing HTML files.

Google Chrome browser without any doubt has the best organization for viewing source code. By right-clicking on the page, you can select “View page code” and then the source code with syntax highlighting will be opened in a separate tab. Or you can select the line “View element code” in the same menu and the browser in the same tab will open two additional frames in which you can inspect the HTML and CSS code of any page element. The browser will respond to the cursor moving across lines of code by highlighting elements on the page that match that section of HTML code.

In the Apple Safari browser, expand the View section and select View HTML Code. In the menu that appears when you right-click on an open page, the corresponding item is called “View source”. The hotkeys assigned to this action are CTRL + ALT + U. The source code opens in a separate browser window.

Quite a lot of people, having encountered difficulties in computer games that they cannot overcome, use special codes to solve this or that problem or simplify the game. A cheat code is a code that can be entered into a computer game in order to change the course of its operation. Entering such codes is carried out by reproducing a certain text (consisting of letters or numbers) on the keyboard. You can also enter text in specially designated areas (game menu or console). How can I find the code for the game?

You will need

• Internet

Instructions

Let's consider the first method using the popular example http://chemax.ru. In order to find a code for a specific game, click on the “Cheat Codes” tab, and then select “In the language”. In the window that opens, you can either enter the name of the game in a special line (which will facilitate the search process), or click on the English or Russian letter with which the name of the game begins. Once you select a game, you will see text that lists all the possible codes.

In order to download the cheat code database, you need to go to the website http://chemax.ru and select the “CheMax” - “CheMax Rus” tab. This database of cheat codes is also Russian-language and has a huge number of games represented. When installing, you should select the Russian language and the location of the program on your hard drive. After you launch the program, you need to enter the name of the game in a special line, as a result of which you will receive all the necessary cheat codes.

Please note

Do not forget to update this program promptly in order to have the most complete code base.

Useful advice

Try to complete the game without using cheat codes, because completing the game honestly will give you much more pleasure.

Let's look at how to determine the source code of a page, because this parameter is very important when working on the Internet. If you need any news, tags or a picture, but you don’t know how to write it, you can always copy information from another site by finding out the source code of the page, if it is not coded by the site developers. What is important is the source code in page files, which are not programs; using the source code, you can work with pages and edit them.

• Instructions for viewing the source code of the page.

Instructions

To be visible, it is written with the source code. You can upload it with the code if you are the owner of the resource, or change it using notepad, an editor, using special extensions for this. The user can also change the page by editing the file and adding his own . In browsers, viewing the source code is carried out using various commands; let's look at them in more detail.

For Internet Explorer, select the “view” tab, then “page source code” or the item can be selected by clicking the right mouse button. To have the code encrypted by the developers in this, go to the “service” menu, then “developer tools”, click the arrow, select the desired element on the page and the code becomes visible. Next, click on the icon and save the code in text format and copy from its components into html.

The Mozilla Firefox browser provides the ability to view using a simple command “Ctrl+U” or in the “tools” menu select the substring “view source code”. You can view encrypted information in Mozilla Firefox by installing a special Web Developer extension, select the “generated code” line in the “code” menu and the value of the source code appears at the bottom of the page. Copy the file to the clipboard or save it with the extension page.htm.

When using Google Chrome, in the main “tools” menu, select the “view source code” substring, then use the right mouse button to open the “view page code” item or use the “Ctrl + U” keys.

To find the source code of the Opera browser, in the “view” menu, select “development tools” and in it the item “page source code” or use the keyboard shortcut “Ctrl + U”.

For the Safari browser, in the menu we find “view html code”, also by right-clicking, open the substring “view source” or use the keyboard shortcut “Ctrl + Alt + U”.

Please note

The ability to view encrypted information about the source code is carried out using two browsers.

Useful advice

If you are not a site developer, you can change the page only for your own use.

In computer games, as in real life, there is an opportunity to cheat a little. For this purpose, developers provide their products with various codes, using which from the game menu you can easily complete levels and missions.

You will need

• CheMax software.

Instructions

To find out the codes that were once used by developers during testing, it is not at all necessary to open all exe files of the game product using HEX editors. You just need to go to a specialized site for cheats using the following link http://chemax.ru.

On the loaded page, move the cursor to the menu bar, namely the “Cheat Codes” section, and in the list that appears, select “In language”. On the next page, enter the name of the game in the search bar, then click the “Search” button. It is recommended to enter the most complete name, which can be copied from the shortcut properties. To do this, go to the desktop and right-click on the game shortcut. In the context menu, select “Properties” and copy the name using the keyboard shortcut Ctrl + C or Ctrl + Insert.

From the search results, select the most appropriate option to open the code table. In addition to the table of codes, if you scroll to the bottom of the page, you can also find a list of trainers with active links. To quickly access the necessary codes before you remember them, it is recommended to select and copy the information from the downloaded page, then paste it into a new text document.

Constantly accessing the site in order to obtain the necessary code is a very long task, because... launching a special program (CheMax) is many times faster. To do this, go to the CheMax top menu and select CheMax Rus. On the program download page, click on the “Installer” or “RAR Archive” link and specify the location to save the executable file.

After installing the program, a shortcut will be placed on the desktop, launching which will open the program. During the game, press "Pause" and use the Alt + Tab combination to navigate to an open window. In the search bar, enter the name of the game and press Enter.

The program code may vary in terms of privacy - many developers do not make it publicly available and the terms of the license agreement impose restrictions on users regarding its use and viewing. There are also open source programs that can be viewed, edited, and so on.

You will need

• - a program for opening source code.

Instructions

Make sure that the source code of the software you want to view is open source. To do this, go to the official website of the software developer and view the license type. If the source code of the program is closed, you cannot view it. This is inconvenient, but with such a system it is quite rare to encounter copies of a program containing Trojans and other malicious programs. This is the main disadvantage of free software.

It’s very simple - just right-click on it and select the appropriate item in the context menu. The wording may vary depending on the browser you are using: in Mozilla Firefox it is called "Source", in Apple Safari - "View Source", in Google Chrome - "View Page Code", in Opera - "Source Code", in Internet Explorer - " View HTML code."

The source code of server scripts that generate the HTML code of the page with normally configured server software cannot be obtained with a simple request. You can view the source code of PHP or Perl scripts only by downloading their files via FTP protocol or through the file manager of the hosting control panel or site management system. You can open such files with a regular text editor.

The source code of client-side scripts that run directly in the browser (for example, JavaScript) can be viewed by extracting their files from the browser cache. And it’s even easier to save pages with all the accompanying files to a specific location. In this case, you won’t have to dig through everything stored in the cache. To do this, in any browser you need to press the key combination CTRL + S, and then in the “File type” field select “Full web page”. You can also open files with the js extension containing the source code of the script using a regular text editor.

The source code of Flash movies that are downloaded by a browser to your computer is not so easy to view. The browser does not receive the source code, but only its compiled version - the executable code. However, there are decompiler programs that can perform the reverse conversion procedure. For example, Trillix's Flash Decompiler is built into your browser and allows you to extract a Flash object from a page and save it. By then opening the flash in the decompiler, you will have access to its individual components - images, scripts, sounds, etc. Of course, this code will not fully correspond to the author’s source code, but only with a degree of accuracy sufficient for operation.

“Source code” most often refers to the code of a program in a human-readable (high-level) programming language. Having this code, you can make changes to the program (script, flash movie, java application, application program, etc.). The author or distributor of the program determines whether to distribute the source code along with the finished product. There is a whole class of applications that are distributed “open source”; the source code of other programs (for example, JavaScript scripts or HTML pages) by definition cannot be hidden, and the source code of other programs is subject to copyright.

Instructions

Get the open source source code of the application on the website of the author or distributor of this software product. You can usually find out the website address in the menu section called “Help” if you select the “About the program” item in it.

Right-click a web page if you want to access its source code. In any browser, the pop-up context menu will contain a command to view the source, although the wording may vary slightly. You can do without the context menu - the key combination ctrl + u duplicates the call to the source view command. Some browsers have built-in viewing tools (Mozilla Firefox, Google Chrome), others use external programs for this - most often Notepad. You can save the page source obtained in this way to a file.

In many knowledge, many sorrows

The availability of source code does not mean that it is automatically provided free of charge. This approach is only true for open source products; in other cases, manufacturers may charge for the source code or make it available upon request.

Hardware development. This also includes source code, which is especially true for development using VHDL and Verlog. How are things going here? Historically, when selecting an integrated circuit and designing its application, the engineer relied on specifications that specified functionality, pinout, power requirements, etc. And at the same time, no one expected to see a complete diagram of the internal structure of the IC, although they could often see a block diagram (mainly as illustrative material that made it easier to understand the principles of operation), and sometimes even a circuit diagram (for analog ICs such as op-amps), although no denominations.
An engineer designing an ASIC or FPGA firmware today will likely use some pre-built IP blocks - a pre-packaged block that provides specific functionality. However, the choice will be based on specifications, and it is not at all obvious that the original HDL for IP will be included in the package. This black box approach is well known in the hardware world.

Safety. Any technology that is included in a product should be selected with future technical support in mind. For example, when selecting IP, you should avoid using unique products from a single manufacturer, which can mitigate problems with supply disruptions.
When using IP, be it hardware or supplied software, supply failures as such are unlikely to occur (except in the case of one-time licenses), but ongoing support must be present. Therefore, the question of whether your supplier will be in business for the entire life of your product is best asked before choosing a specific implementation.

If the source code for an IP is available, it makes it possible to resolve any (well, almost any) software problem, even if the vendor is no longer able to offer support. For this reason, many buyers of RTOS, etc. would like to have the source code on the shelf even if they never look at it, just in case.

Software Customization The main difference between embedded systems and desktops is the variability of the former. Most PCs are similar to many others and the only choice is between the execution environment: Windows, Mac, or Linux. Embedded systems, on the other hand, are incredibly variable - varying processors, memory configurations, and peripherals. As a result, IP software must be flexible so that it can be deployed on a variety of systems. Although many products such as RTOS are delivered in binary form - typically a library that is customized to a specific architecture - source code delivery requirements can incentivize vendors by eliminating the need to store and support multiple variations, since providing IP as source solves many of these issues. The user can build code for a specific processor, adapt it to the device's memory card, and add the necessary device extensions. In some cases, an IP block can be configured using conditional compilation - typically a header file is edited to define the configuration.

Certification. For some types of applications, such as military/aviation and medical, the firmware must be certified for safety and compliance with various standards. This process is complex and expensive and usually entails checking every line of code. Therefore, it is usually not possible to purchase "pre-certified" software units since the entire application is subject to review. Thus, a mission-critical application developer will likely look for an IP that is available along with the source code so that full verification can be performed.

What is Source Code?
The question may seem strange, but without an answer, discussing any aspects of its presence (or absence) turns into a somewhat strange exercise. The answer may seem obvious: the source code of a program is a collection of files containing high-level or assembly language instructions that can be compiled and assembled into functioning binary instructions. Immediately the question is - are the programs necessary for the transformation process and the execution environment for them part of the source code (in binary form)? Nevertheless, this definition meets at least 3 forms in which “source code” can be supplied (for example, let's talk about the C language) in order of deteriorating quality:
1) Really source code, with a good layout, clear variable naming conventions and well commented (provided that the IP developer has one, which is completely optional).
2) Lines of code that will compile successfully BUT without comments or particularly meaningful identifier names.
3) Lines of code after obstruction, which makes the code unreadable by humans, but acceptable to the compiler. This is done by replacing identifier names with meaningless ones and removing all comments and syntactically unnecessary spaces. There is a reverse process, but its results can hardly be called acceptable.
All these forms are used by software providers for the following purposes:
1) is what most buyers expect to receive and what many manufacturers actually provide. However, when making a purchasing decision, if you require source code, it is important to ensure that this is the option; if in doubt, just ask for samples.
2) usually used when the seller wants to deliver the minimum required, which may be (only) good enough for certification.
3) is used to protect the contents of the IIP from prying eyes, which means that the software gets the benefit of configurability, but nothing more.

Disadvantages of the source code.
The biggest disadvantage of having the source code available: it's very tempting. Every developer wants to make their software as good as possible (well, there is such a point of view). So, for example, if the RTOS API does not work exactly to be optimal for the application, the availability of the source code provides an opportunity to change it.
While it may seem like a great thing to make an application optimal, there is a problem with long-term support. What if there is a problem with RTOS functionality? Supplier will not support the modified product. What to do if a new version of the RTOS is released? Including it in a redesign may require significant time for repeated modifications, especially if their author no longer works for you (well, either you made these modifications 3 years ago and of course, or, as they say, of course, you didn’t bother writing the appropriate documentation).

Having considered the situations in which source code may be desirable, useful, or necessary, the conclusion is that it is not absolutely and always required. If you are purchasing an IP from a large, well known and stable provider that can offer long term support, then having the source code is not relevant and may even be listed as a disadvantage.

The source code of a site is a collection of HTML markup, CSS styles and JavaScript scripts that the browser receives from the web server.

It can be compared to a set of commands given to soldiers by a commander. Imagine that the audience does not see or hear the boss. From their point of view, the military carries out actions independently. In our case, the commander is the browser, the commands are the source code, and the marching soldiers are the final result.

The site is stored on a web server, which sends the page upon user request. A request is typing a URL in the address bar, clicking a link, or clicking a submit button on a form. It doesn’t matter what language the web pages are written in or whether they include a software component. The end result of any server-side algorithm is a set of html tags and text.
The page source code is a set of data that includes:

• html markup;
• style sheet or file link;
• programs written in JavaScript or links to files with code.

These three sections are processed by the browser. For the server, this is simply the text that needs to be sent in response to the request.

Why we might need to study the source code

Everything we see, we can analyze and apply to solve certain problems that arise while working with the site, especially when optimizing it. By looking at the source code, we can:

• See the meta tags of your or someone else’s site to analyze them.
• See the presence or absence of certain elements on the site: counters, identification codes in various systems, certain scripts and other things.
• Find out the parameters of the elements: sizes, colors, fonts.
• Find the path to photos and other elements located on the page.
• Explore links from the page.
• Find problems with the code that interfere with the process of site optimization: styles not placed in separate files, scripts, invalid code.

These are the basic features, but in fact, by being able to read the code, you can learn a lot more about the page.

How to view the source code of a site

It will not be possible to do this completely in the form in which it is posted on the server from the browser. But you can see all the markup by right-clicking on the page. Here and below using Google Chrome as an example.

Select the “View page code” option and get the full listing in a separate tab.

It's just text that you have to analyze to understand. But you can get interactive code using the developer tools.

How to find the source code of a website page

Click on the menu icon in the browser. Most often it is on the right and looks like three dots or stripes.

In the additional tools section, select “Developer Tools”.

A window will open showing the active state of the code. This means that when you click on the markup, the element style will appear next to it, and the selected blocks will be highlighted on the page.

In the “Source” tab you can view the contents of some files: scripts, fonts, images.

In the “Security” tab, you can check the site’s certificate.

The “Audits” tab will help you check the resource posted on the hosting.

If the location of the panel on the right is inconvenient, you can click the three dots and change it by selecting the desired item.

How to view meta tags

Every HTML document includes structure tags. Here are some of them:

1. Html – the entire document.
2. Head – section of service headers.
3. Title – page title (displayed on the tab).
4. Body – the body of the document.
5. H1-H6 – page text headings.
6. Article – article.
7. Section - section.
8. Menu – menu.
9. Div – block.
10. Span – string.
11. P – paragraph.
12. Table – table.

Elements are designed to logically delimit sections on a page; if necessary, they are designed using styles. They contain text that is somehow visible on the page. But the Head tag contains service information. Meta tags are used to indicate it. Everything that is written in them is intended for the server and search engines.

Their contents cannot be found out in any other way.

Let's pay attention to the Link tag. With its help, links to external included files are specified. If desired, you can see the contents and save to disk. To do this, move the pointer to the address and press RMB. Select "Open in new Tab".

The specified file will open in a new tab, which you can view or save.

How to view the source code of a page to debug a script

In this case, it is most convenient to open the page on the local machine. If you only need to correct markup, styles and scripts, then this can be done directly from the folder. The HTML code is viewed in the same way. But JavaScript code errors can be seen in the “Console” tab. This shows the description of the error and the line number where it occurred.

The syntax can be seen directly in the code. This is what the “Source” tab is for.

How to view the code of a specific element

For large pages with many elements, it is difficult to find the necessary code in all the markup. In this case, you should use a special context menu command. Move the mouse over the fragment and press RMB. Select the “View Code” command.

The same window will open, but with the focus on the selected object.

Resume

We told you what the page source code is. It is enough to master basic knowledge of HTML and CSS, and using convenient developer tools, you will be able to debug your own HTML documents.

Reviewing the code of resources on the Internet will allow you to learn not only from your own experience, but also to use real working examples. And for SEO specialists, meta tags will be useful, the information in which can tell a lot about the site.
