Synergy DBL and Visual Studio Code

By Steve Ives, Posted on October 10, 2019 at 2:52 pm

Steve Ives

Some time ago a customer posted in the Synergy/DE Ideas forum suggesting that a Synergy DBL language plug-in should be created for the increasingly popular Visual Studio Code editor. Over course of the next few months the post received a significant number of votes, and we also started hearing the same request from others.

Later we heard from the original customer that they had started to define some basic language integration themselves, offered to share that initial code, and agreed that it could be open sourced.

At this time we are pleased to announce that initial support for DBL in VS Code is live! We have developed this functionality as an open source project on GitHub (https://github.com/Synergex/vscode-synergydbl) and welcome your feedback and your contributions.

If you just want to try the extension you can search for “Synergy” in the extension marketplace inside of VS Code, or download and install the VSIX from the GitHub Releases page. If you do try the extension out, and have questions or problems, please use the GitHub Issues page to let us know.

The initial scope of the extension is fairly limited, but we have been using the colorization locally for a while now and it makes a huge difference when you just need to do a quick edit to a source file. We are looking forward to seeing what everyone else has to contribute.


CodeGen 5.4.3 Released

By Steve Ives, Posted on September 22, 2019 at 1:01 pm

Steve Ives

I am pleased to announce that another new version of CodeGen has been released, is available for immediate use, and contains several powerful new features:

  • We added a new structure expression token <IF STRUCTURE_PII_FIELDS> that indicates whether any field in a structure has been tagged as containing PII (Personally Identifiable Information). We also added a new field loop expression token <IF PII_SCRUB> that indicates whether a field has been tagged as containing PII data, and a new field loop expansion token <FIELD_PII_TYPE> which inserts the type of PII data a field contains.
  • We added a new field loop expression token <IF USED_IN_RELATION> that can be used to determine whether the field currently being processed is involved in any relations to other structures.
  • We added a new custom field loop expression token <IF HARMONYCORE_CUSTOM_FIELD> and a new custom field loop expansion token <HARMONYCORE_CUSTOM_FIELD_TYPE> to the Harmony Core extensions assembly. In a future release Harmony Core will use these new features to allow developers to easily implement support for custom field types that may be implemented within their applications data set.
  • We added a new tag loop expansion token <TAGLOOP_FIELD_SNTYPE> and relation key segment loop expansion token <LITERAL_SEGMENT_SNTYPE>.

Additionally, because the Symphony Framework is no longer maintained by Synergex, and is no longer an open source development effort, we have decided to discontinue the distribution of the “Symphony Framework CodeGen Extensions” assembly that was formerly distributed along with CodeGen. We continue to support the addition of custom extensions and the Symphony Framework extensions can be added back at any time by any Synergy developer with the necessary Synergy .NET development tools.

This version of CodeGen was built with Synergy/DE 11.1.1 and requires a minimum of version 10.1.1 to operate.


Enhanced CodeGen CreateFile utility

By Steve Ives, Posted on August 26, 2019 at 9:58 pm

Steve Ives

For some time CodeGen has shipped with a utility called CreateFile that (given an appropriately configured repository) could be used to create an ISAM file based on a repository FILE or STRUCTURE definition.

A customer recently asked me to create a mechanism that they could use to create multiple files, load data into those files, and also support creating both RELATIVE and ISAM files. Rather than writing something completely new I decided to extend the CreateFile utility, and that new feature has now been released along with the latest version of CodeGen (5.4.2).

Briefly, there is a new command line option -in that allows you to specify an input file containing the details of one or more files to be created and and populated. The file uses a JSON format. If you’re interested in finding out more you can find additional information in the CodeGen documentation.


CodeGen 5.4.0 Released

By Steve Ives, Posted on July 3, 2019 at 9:59 am

Steve Ives

It’s been a while since a GodeGen release was announced on this BLOG, but rest assured they have been coming thick and fast; in fact there have been 9 interim releases since we last announced here.

So why all the frenetic activity in CodeGen land? Well the primary driving force for so many releases and so many new features is to provide support for the ever evolving Harmony Core RESTful Web Services framework. If you’re not familiar with Harmony Core then you should check it out. More and more Synergy developers are starting to take advantage of it as a way to expose their applications data and business logic in whole new ways and to support a myriad of use cases.

So what’s new in CodeGen 5.4.0? Well the answer to that question is … a LOT! I won’t list all the new features here but if you want to check out the specifics then you can head over to the CodeGen Releases page where you’ll find a detailed change log for this and previous versions. And if you need more information than that then check out the CodeGen Documentation.

We recommend that all developers who are using CodeGen upgrade to this latest version, but particularly if you’re developing with Harmony Core.

Happy 4th Everyone!


CodeGen 5.3.6 Released

By Steve Ives, Posted on September 23, 2018 at 4:43 pm

Steve Ives

Just a quick note to announce that CodeGen 5.3.6 has been released and is available for immediate use. This latest version represents the culmination of a series of recent releases which together have added significant new features across the entire product, including the ability to generate code based on metadata found in the xfServerPlus Synergy Method Catalog.

Many of the new features were added specifically to support code generation for the new Harmony Core RESTful web services framework that we are excited to be introducing at the upcoming DevPartner Conference in New Orleans next month.

If you are joining us for the post-conference Harmony Core workshop then you will need to have this new version of CodeGen installed on your development system; you can download it here. And even if you’re not intending to use the new Harmony Core framework, there are many new features that may be useful to all CodeGen users; we recommend this release for general use.

We’re looking forward to seeing you all in New Orleans between October 8th and 12th. If you haven’t signed up yet, it’s not too late! You can still sign up here.


CodeGen 5.2.3 Released

By Steve Ives, Posted on December 1, 2017 at 11:18 pm

Steve Ives

We are pleased to announce the release of CodeGen version 5.2.3. The new release includes new features, addresses some issues found with previous releases, and also paves the way for once again being able to use CodeGen on non-Windows platforms through experimental support for the .NET Core environment.

As always, you can download the latest version of CodeGen from here.

CodeGen Version 5.2.3 Release Notes

  • Added a new experimental utility to the distribution. The Code Converter utility can be used to automate bulk searches within and bulk edits to an applications code. This utility is in a usable form. However, it is still a work in progress and is likely to undergo substantial changes as it evolves.
  • Added two new utility routines (IsDate.dbl and IsTime.dbl) that are referenced by some of the supplied sample template files.
  • Corrected a regression that was introduced in the previous release which caused the field loop expansion token <FIELD_SQL_ALTNAME> not to default to using the actual field name if no alternate name was present.
  • Performed an extensive code review and cleanup, updating the code in several areas to take advantage of new features available in the Synergy compiler, and also improving efficiency.
  • Fixed an issue that was causing the CreateFile utility -r (replace file) option to fail, an existing file would not be replaced even if the -r option was specified.
  • Fixed an issue in the CreateFile utility that would result in an unhanded exception in the event that invalid key information was passed to XCALL ISAMC.
  • Made some minor code changes to allow CodeGen to be built in a .NET Core environment and we hope to be able to leverage .NET Core to once again support the use of CodeGen on non-Windows systems (starting with Linux) in the near future.
  • This version of CodeGen was built with Synergy/DE 10.3.3d and requires a minimum Synergy version of 10.1.1 to operate.

Symphony Framework Components

  • We no longer ship the Symphony Framework sample templates with CodeGen. You can obtain the latest Symphony Framework templates from the Symphony Framework web site (http://www.symphonyframework.net).
  • There were no Symphony Orchestrator changes in this release.
  • There were no Symphony Framework CodeGen Extensions changes in this release.

CodeGen 5.2.2 Released

By Steve Ives, Posted on October 25, 2017 at 3:00 pm

Steve Ives

We are delighted to announce the availability of the CodeGen version 5.2.2 release that includes the following enhancements and changes:

CodeGen Version 5.2.2 Release Notes

  • Added a new field loop expansion token <FIELD_FORMATSTRING> which can be used to access a fields format string value.
  • Added a new command-line option -utpp which instructs CodeGen to treat user-defined tokens as pre-processor tokens. This means that user-defined tokens are expanded much earlier during the initial tokenization phase, which in turn means that other expansion tokens may be embedded within the values of user-defined tokens.
  • Removed the RpsBrowser utility from the distribution; it was an experimental project that was never completed.

This version of CodeGen was built with Synergy/DE 10.3.3d and requires a minimum Synergy version of 10.1.1 in order to operate.


CodeGen 5.2.1 Released

By Steve Ives, Posted on August 24, 2017 at 2:10 pm

Steve Ives

We are pleased to announce the release of CodeGen 5.2.1 which includes several new features that significantly extend the possibilities for what can be generated. The core goal for this release was to introduce new features that make it possible to sub-divide the processing of large loops into smaller units of code, and by doing so make it possible to achieve new things, especially when working with very large structures.

For example, the reference code that demonstrates how to implement the replication of ISAM data to a relational database (https://github.com/SteveIves/SqlReplicationIoHooks) previously had a restriction that it could only deal with files (tables) with up to 252 fields (columns). The underlying reason for this related to the maximum number of arguments that can be passed to an external routine, %SSC_BIND in this case. The restriction of 252 available data parameters to %SSC_BIND meant that bad code would be produced for any structure with more than that number of fields. Now however, using some of the new features in CodeGen 5.2.1, the template has been re-structured so that %SSC_BIND will be called multiple times if necessary, removing the previous restriction.

But that’s just one example, there are doubtless many more. Here are the release notes for the new version:

  • We added several a new generic expression token <IF COUNTER_n_op_value> that allows you to write conditional template code based on testing the current value of the two internal template counters against a simple numeric expression. Here is an example of using this new expression:
<IF CODEGEN_COUNTER_1_EQ_10>
Code to include for every 10th item
</IF>
<IF TOTAL_ITEMS_LT_50>
Code for a small number of items.
<ELSE>
Code for a larger number of items.
</IF>
<REQUIRES_CODEGEN_VERSION>5.2.1</REQUIRES_CODEGEN_VERSION>
  • We made a minor correction to the documentation of the -f l command line option. The documentation previously stated that this option caused fields marked as “Excluded by Language” to be EXCLUDED from field loop processing, but actually such fields are excluded by default. The -f l command line option actually suppresses this behavior, causing such fields to be INCLUDED in field loop processing.
  • This version of CodeGen was built with Synergy/DE 10.3.3c and requires a minimum Synergy run-time version of 10.1.1.

The latest version of CodeGen can always be downloaded here.


Developing in Visual Studio

By Steve Ives, Posted on June 30, 2017 at 7:56 pm

Steve Ives

Most Synergy developers would love to use the very latest and greatest development tools to develop and maintain their Synergy applications, but how do you get started? At the recent DevPartner conference in Atlanta product manager Marty Lewis not only discussed the concepts of how to get started, but actually demonstrated the entire process with a real Synergy application. Check out his presentation entitled Developing Synergy Code in Visual Studio:

By the way, this video is just one of many from the 2017 DevPartner Conference.


CodeGen 5.1.9 Released

By Steve Ives, Posted on May 12, 2017 at 8:45 am

Steve Ives

I am pleased to announce that we have just released a new version of CodeGen (5.1.9) that contains some new features that were requested by customers. The changes in this release are as follows:

  • We added two new structure expansion tokens <FILE_ODBC_NAME> and <FILE_RPS_NAME> that expands to the repository ODBC table name or structure name of the first file definition that is assigned to the structure being processed.
  • We made a slight change to the way that the multiple structures command line option (-ms) is processed, allowing it to be used when only one repository structure is specified. This allows for templates that use the <STRUCTURE_LOOP> construct to be used when only one structure is being processed.
  • We also fixed an issue that was causing the <FIELD_SPEC> token to produce incorrect values for auto-sequence and auto-timestamp fields. Previously the value 8 would be inserted, now the correct value i8 is inserted.

This version of CodeGen was built with Synergy/DE 10.3.3c and requires a minimum Synergy runtime version of 10.1.1. You can download the new version directly from the CodeGen Github Repository.


Build RESTful Web APIs at the DevPartner Conference

By Steve Ives, Posted on February 23, 2017 at 10:23 pm

Steve Ives

Today we published the agenda for the 2017 DevPartner Conference which will take place in Atlanta, GA the week of Monday May 8th; we hope you can join us. The main conference will be a three-day event from Tuesday May 9th through Thursday May 11th. And similar to other recent conferences we will be offering both pre- and post-conference workshops on Monday 8th and Friday 12th respectively. I will be hosting the pre-conference workshop entitled “Building RESTful Web Services with Synergy .NET and ASP.NET Web API”. My colleague Richard Morris will be presenting the post-conference seminar entitled “Building Platform-Independent Mobile Apps with Xamarin Forms”. Of course we hope you can join us for both workshops, but for the remainder of this article I will be focusing on providing information about the pre-conference RESTful web services workshop.

Building and implementing web service APIs isn’t exactly new, but there are definitely some new and exciting technologies in play that can make building, deploying and interacting with web services faster, easier and more powerful than ever. With the relentless increase in demand for mobile applications and solutions the requirement to expose web service APIs is greater than ever. Not that web service API’s are only used to support mobile applications, that is certainly is not the case. In fact almost any new application developed today is likely to either require the use of a web service API, or it will just make sense to architect the application that way for increased flexibility and future-proofing.

I’m developing the content for my workshop right now and I wanted to give you some information about the audience that I am targeting, which is very broad. To be honest, unless you are already implementing RESTful web service APIs then this workshop is for you! And even if you ARE already implementing RESTful web services APIs, but with some technology other than ASP.NET Web API, then this workshop is also for you! In my opinion it is really important that every developer have at least a good understanding of what a RESTful web service APIs are and how they can be used, and it sure doesn’t hurt to know how to build them either! This workshop will teach you all of those things, and more.

We will start with the basics and will not assume any previous knowledge of web services. After an introductory presentation there will be lots of code, so you will need to be comfortable with that. I don’t want to just show you how to build a RESTful web service API, I want you to really understand what it is and how it works. So as well as covering ASP.NET Web API we will also be talking about the basic principles of REST, as well as various underlying technologies like HTTP, JSON and XML. If it all works out as planned it should be an action packed and interesting day.

This year both of the full-day workshops will be lecture and demonstration based; there won’t be any hands-on component. Unfortunately the hardware and software requirements of the underlying technologies that we will be using, particularly in the post-conference workshop, make it virtually impossible for us to offer a hands-on experience this time around. But rest assured that you will have access to all of the code that is developed and demonstrated, and we’ll make sure that you know exactly what hardware and software you will need if you want to work with that code, or perform your own similar development projects.

Time is ticking away and DevPartner 2017 is only about 10 weeks away. We’re all looking forward to seeing you again, or meeting you for the first time, and if you haven’t done so already then it’s time to register. See you there!


CodeGen 5.1.7 Released

By Steve Ives, Posted on February 7, 2017 at 10:25 am

Steve Ives

We are pleased to announce that Professional Services has just released CodeGen 5.1.7. The main feature of the release is the addition of experimental support for generating code for the MySQL and PostgreSQL relational databases. Developers can use a new command line option -database to specify their database of choice. This causes the SQL-compatible data types that are injected by the field loop expansion token <FIELD_SQLTYPE> to be customized based on the chosen database. The default database continues to be Microsoft SQL Server.

Before we consider support for these new databases to be final we would appreciate any feedback from developers working with MySQL or PostgreSQL to confirm whether we have chosen appropriate data type mappings. Additional information can be found in the CodeGen documentation.

 


CodeGen 5.1.6 Released

By Steve Ives, Posted on November 7, 2016 at 4:31 pm

Steve Ives

I am pleased to announce that we have just released a new version of CodeGen with the following enhancements:

  • We modified the way that key loops are processed so that if a repository structure has a mixture of access keys and foreign keys defined, the foreign keys are ignored when processing key loops.
  • We added a new key loop expression <IF FIRST_SEG_NOCASE>.
  • We added four new field loop expressions <IF AUTO_SEQUENCE>, <IF AUTO_TIMESTAMP>, <IF AUTO_TIMESTAMP_CREATED> and <IF AUTO_TIMESTAMP_UPDATED> which can be used to determine if fields are defined as auto sequence or auto time-stamp fields.
  • We added two new key loop expressions <IF AUTO_TIMESTAMP_CREATED> and <IF AUTO_TIMESTAMP_UPDATED>.
  • We added two new key segment loop expressions <IF SEG_AUTO_TIMESTAMP_CREATED> and <IF SEG_AUTO_TIMESTAMP_UPDATED>.
  • We changed the behavior of the field loop expansion token <FIELD_TYPE_NAME> when used in conjunction with auto-sequence and auto-time-stamp fields.

This version of CodeGen is built with Synergy/DE 10.3.3a, requires a minimum Synergy runtime version of 10.1.1, and can be downloaded from here.


CodeGen 5.1.4 Released

By Steve Ives, Posted on July 29, 2016 at 10:42 am

Steve Ives

We are pleased to announce that we have just released CodeGen V5.1.4. The main change in this version is an alteration to the way that CodeGen maps Synergy time fields, i.e. TM4 (HHMM) and TM6 (HHMMSS) fields, to corresponding SQL data types via the <FIELD_SQLTYPE> field loop expansion token. Previously these fields would be mapped to DECIMAL(4) and DECIMAL(6) fields, resulting in time fields being exposed as simple integer values in an underlying database. With this change it is now possible to correctly export time data to relational databases.

We also made a small change to the CodeGen installation so that the changes that it makes to the system PATH environment variable occur immediately after the installation completes, meaning that it is no longer necessary to reboot the system after installing CodeGen on a system for the first time.

This version of CodeGen is built with Synergy/DE 10.3.3a and requires a minimum Synergy runtime version of 10.1.1.


Replicating Data to SQL Server – Made Easy

By Steve Ives, Posted on July 28, 2016 at 5:29 pm

Steve Ives

For some time now we have published various examples of how to replicate ISAM data to a relational database such as SQL Server in near to real time. Until now however, all of these examples have required that the ISAM files that were to be replicated needed be modified by the addition of a new “replication key” field and the addition of a corresponding key in the file. Generally this new field and key would be populated with a timestamp value that was unique to each record in the file. While this technique guarantees that every ISAM file can be replicated, it also made it hard work to do so because the record layout and key configuration of each ISAM file needed to be changed.

However, almost all ISAM files already have at least one unique key, and when that is the case one of those existing those keys could be used to achieve replication without requiring changes to the original record layouts or files. When this technique is combined with the capabilities of I/O hooks it is now possible to achieve data replication with only minimal effort, often with no changes to the ISAM files being replicated, and with only minimal modification of the original application code.

I am pleased to announce that I have just published a new example of doing exactly that. You can find the example code on GitHub at https://github.com/SteveIves/SqlReplicationIoHooks. Of course if you are interested in implementing data replication to a relational database but need some assistance in doing so, then we’re here to help; just contact your Synergex account manager for further information.
