MarkShark 27 Posted June 22, 2020 Hey all. I use SynEdit in a few projects and I was wondering if anyone has insight on which of the various version is the preferred one to use. I'm on 10.4 and don't need backwards compatibility btw. The one that is on "GetIt" appears to be an older version (1.5.) The one listed as SynEdit2 on github by pyscripter appears to be active, includes some nice changes (ole drag and drop for example) lots of fixes and cleanup (some related to removing support for older Delphi versions.) The one listed as SynEdit/SynEdit on github which seems to be more actively developed then the other two. I've worked with the second two and, as always, it seems when working with third party components I have to make a few changes to the source (adding some missing properties, fixing the extra space on word wrap lines (thanks to a stack overflow answer) and a few other minor issues) which have to be merged into each new update, so picking the "correct" one will obviously help. On a side note I have a feeling that the correct answer might be that there is no correct answer... Just looking for any feedback or thoughts. And this post wouldn't be complete without thanking and acknowledging all the great work people have done on these projects! -Mark 2 Share this post Link to post
Darian Miller 353 Posted June 22, 2020 I'm currently in the same situation of looking at the SynEdit-2 vs SynEdit. I originally picked SynEdit-2 by Pyscripter due to his changes, but am now using the github/SynEdit version due to Gutter.ShowModification support. Do you have your customizations on GitHub somewhere? The word wrap issue (assuming: https://stackoverflow.com/questions/54494905/how-to-make-tsynedits-wordwrap-same-as-tmemos) is a problem in all 3 of the projects. I haven't checked out the FPC version yet. Have you tried a pull request of your modifications to either SynEdit or SynEdit-2? Share this post Link to post
pyscripter 612 Posted June 22, 2020 (edited) I will start with a bit of history. The Original Code is based on mwCustomEdit.pas by Martin Waldenburg, a great programmer. The key feature of the editor was fast syntax highlighting. This was more than 20 years ago. After a split of the community the SynEdit project was formed maintaining some of the key features of mwEdit. Over the years some of the best Delphi programmers contributed to the project. The list includes for example Gerald Nunn, Eric Grange, Jordan Russell and many many others. Flavio Etrusco added word wrap and Maël Hörz added unicode support (but in a rather idiosyncratic way). However the project management was very weak and the code gradually became very hard to maintain and improve. It aimed to support very old Delphi versions including Kylix and the code became full of IFDEFs and patches without an overall coherence. An early fork of Synedit is part of Lazarus but the two development efforts have diverged a great deal. When Embarcadero introduced the GetIt package manager they asked Roman Kassebaum to produce a version of SynEdit for GetIt. Roman did a general code cleanup removing support for early Delphi versions and Kylix (Turbo fork(s)). I have added support for code folding (the first major new feature for years) to both the Turbo fork and the main Synedit repository. However the Turbo fork(s) were not actively supported or developed beyond recompiling for new Delphi versions and the main Synedit branch was too hard to work with, hence the creation of SynEdit-2 as a fork of Turbo SynEdit. Main new features in SynEdit-2: Replaced SynRegExpr with the built-in RegularExpressions Move/Copy Line(s) Up/Down commands as in VS Code Delete Line command should work with multi-line selection Handle triple and quadruple clicks for selection Triple click and drag should select lines Double click and drag should select whole words Support OLE Drag & Drop What are the key features missing in Synedit: Better Unicode handling: Better support for wide characters e.g. Chinese ideograms (爾雅爾雅爾雅爾雅) Support for surrogate pairs (two widechars correspond to one glyph) Combining characters (e.g. Åström ḱṷṓn) Multi-cursor and multi-selection editing as in VS Code. When these features get implemented I think SynEdit will become comparable to some of the best editors around. But both of them require major rewriting of the code. Work on the second is well advanced and the unicode work is in the planning stage. Of course it is your choice as to which version of SynEdit to use, but if anyone wants to contribute to the development you are very welcome.

Unfortunately SynEdit's ShowModification is half-baked and does not work well when you undo. This is why it has not been ported to SynEdit-2. Proper support requires some work in the undo/redo system. Edited June 22, 2020 by pyscripter Share this post Link to post
dummzeuch 1456 Posted June 22, 2020 (edited) Judging from the VERxxx constants in the package source, SynEdit2 supports Delphi 2006 and up, correct? Could you please add that to the project description? @pyscripter Edited June 22, 2020 by dummzeuch Share this post Link to post

Could you please add that to the project description? @pyscripter To be frank I am not sure. Like the Turbo branch it is aimed at the most recent versions of Delphi. The code uses generics and unicode, so that I suppose determines the minimum version. Share this post Link to post

Edwin Yip 154 Posted June 22, 2020 Maybe someone port https://github.com/Alexey-T/ATSynEdit to Delphi? ATSynEdit seems to have a lot more features, including the multi-cursor feature, with active development currently for a long time. Share this post Link to post

VER200 is the first Unicode version (Delphi 2009), It's also the first version that introduced Generics (no idea how usable/buggy they were in that version). Share this post Link to post

Edwin Yip 154 Posted June 24, 2020 Alternatively, I actually quite satisfied with the result of https://github.com/KrystianBigaj/dscintilla It's a Delphi wrapper for scintilla , which is the editor used by Notepad++ and a lot of others. And it's under active development. Share this post Link to post

pyscripter 612 Posted June 24, 2020 (edited) A more advanced wrapper for Scintilla was in http://myarmor.users.sourceforge.net/. I had some involvement in the initial development. But it died many years ago. A more up to date wrapper exists in the Inno Setup source code https://github.com/jrsoftware/issrc/tree/main/Components. However it is based on Scintilla 2.22, when the current version is 4.4... Edited June 24, 2020 by pyscripter Share this post Link to post

However it is based on Scintilla 2.22, when the current version is 4.4... It seems that the myarmor DelphiSci wrapper is more feature-rich, but as you said, it's for v1.x and it's too old, not sure if it works with the latest version. the InnoSetup version also suffers the same issue. On the other hand, the github DScintilla I posted above works with 4.x (at least the version back in a year or so). Actually the DScintilla wrapper communicates with Scintilla through the SendMessage windows API, so it's quite easy to adopt new features. And don't forget , Scintilla is crossplatform (but not wrapper for Delphi on Linux or Mac). Share this post Link to post
MarkShark 27 Posted June 25, 2020 Thanks to everyone who responded to this! I'm new to git (and to contributing to open source projects) so I installed a bunch of stuff, cloned the SynEdit2 repository, made a branch (I think that's the correct thing), went to add the wordwrap fix I mentioned above... and found that pyscripter had already fixed it last December and I had totally missed it. Nice! I'm going to attempt a pull request on a very minor fix I have to try to get my feet wet on the process. 3 Share this post Link to post

Bill Meyer 336 Posted July 2, 2020 I have questions regarding SynEdit-2. What is the earliest supported version of Delphi? What are the dependencies on other packages? I ask because I have tried two versions of Delphi, the latest being 10.2.3, and neither one will build the runtime. Share this post Link to post
pyscripter 612 Posted July 2, 2020 If you are switching from another version of Synedit to Synedit-2 you need to uninstall the current version, remove all compiled packages and install from scratch. As mentioned above I am not sure which is the earliest version supported (same about the Turbo Synedit), however I am quite sure Delphi 10.2 should be good. Share this post Link to post
Edwin Yip 154 Posted September 23, 2021 I've just started using the official github edition and I'm very satisfied so far - well except the word wrapping... I should have used pyscripter's SynEdit-2 if I had a newer compiler ;) Share this post Link to post
