Log files can be extremely useful for troubleshooting. They’re also a big help for finding the root cause of an incident. Logs let us track of where a problem occurred, and when. Before, with the Get 4D folder command, you could easily access the folder containing all the logs. Now, 4D v16 R6 makes easy to find a particular log file, thanks to the enhancement of the Get 4D file command.
4D is making your developer’s life easier with two new commands to effortlessly manage file or folder paths. Save valuable time with the Path to object command which, in a single line of code, extracts the extension, the file name or the parent folder. Then you can modify and recombine the different object attributes to compose a new path with Object to path.
Objects are great! Their flexibility, combined with speed and elegance, make them a first choice for most developers. Using dates inside objects is now easier and more intuitive. From now on, dates can be set as dates – and not strings inside objects!
Quite frankly, we love objects. 4D Write Pro uses objects as the input/output of commands and functions to manipulate documents, text, paragraphs, etc. In this blog post, we’ll show you four different ways to use objects with 4D Write Pro.
There is an old saying: “Old is gold” meaning that new ways are not as good as the old ones. But the new way to say is “Old is gold but new is platinum“. We are not referring to jewelry here but two of 4D commands: MODIFY SELECTION and DIALOG.
The Get process activity command, added with 4D v16 R4, makes it possible to retrieve a list of running processes and connected users. With 4D v16 R5 we’ve further enhanced the command to make parsing the results easier. In addition to that, a new systemID attribute has been added to uniquely identify any process, whatever its type: user, 4D or spare.
This feature is another way of providing you the ability to create your own server administration dialog. Following the ability to retrieve information for all processes (added in 4D v16 R4), we are now offering you a new command which returns, as a whole, all runtime information about 4D Web server.
With 4D v16 R5, retrieving web server information has never been easier, thanks to a single command: WEB Get server info.
In 4D v16 R4, we enriched object commands so you can validate JSON objects. 4D v16 R5 is going even further by introducing the support of JSON pointers. Great – but what is a JSON pointer and what can I do with it?
Just like you don’t store company details for each employee in a database record (using a link to the company record instead), it can be really useful to structure a JSON document with parts that can be reused in a number of places.
For instance, let’s take an example of a website order; the customer enters the shipping address and designates the billing address as the same. Instead of duplicating the address information, we can define the shipping address as a reference to the the billing address.
We’ve received several customer requests to provide the ability to use the 4D Write Pro template with headers and footers to create other documents based on this template. Well, we heard you and this is available in 4D v16 R5.
A new set of commands have been added to 4D Write Pro to fulfill this need. Some of these commands can be used to get references of headers, body and footers inside documents. Others are handy to get a reference to the frame (header, footer, etc.) where the cursor is currently located, or to set the cursor into a specific frame.
With 4D v16 R4, we introduced Object Notation which is a great enhancement to the 4D language: your code is fast, flexible, efficient and elegant! This feature created a lot of interest on the 4D forums and we received a lot of feedback from our customers highlighting situations when there were undefined values making the code challenging to write.
With 4D v16 R5, we have taken your feedback into account and have simplified the use of undefined properties and values with Object Notation.
