Incorporating changes from Standard

[jamespetts]

Thank you for your help. I have tried specifying the objs/.libs directory (which I had not seen before because it was hidden) as a library directory, but sadly this does not assist.

I have to say, I did not know that there was any system for automating the directories for cross-compiling; I am aware that this is normal for native compiling, but I had not found any documentation anywhere suggesting that this was a thing for cross-compiling (after struggling for months to get cross-compiling to work when I first started the nightly build server back in 2017), so I had just set up the directories in the /root folder and linked to them manually, which worked.

As to library configurations, do I understand that freetype needs zlib to work? I am not getting any compile errors, so this is somewhat surprising; what is being compiled if there are dependencies missing? The objs/.libs directory is populated as follows:

I would guess you're not even trying to link it. i.e. missing -lfreetype.    VERBOSE=1 is to help for exactly this type of thing.
Perusing the headache inducing Extended Makefile, the only place that would come from are the "system for automating the directories"...

Do you have freetype-config (for the cross environment)?   freetype2.pc?  (try 'x86_64_w64-mingw32-pkg-config freetype2' [or whatever your cross prefix is])
If so, the paths, libraries, etc. all come from them.
If not, you need to define FREETYPE_CONFIG= as blank in config.default. And same for SDL2_CONFIG, etc., etc.. as per config.template "# Define these as empty strings, if you don't have the respective config program"

zlib is required for freetype, but it includes it's own copy if a 'system' one can't be found. Hence why you still compile.
bzip2 would be needed for certain fonts too, but only the 'system' one.
Since both zlib and bzip2 are needed by Simutrans, I would've expected them to be installed already, but if you've stuck them in some /root/blah path rather than in the 'system', then....

Also note from the warnings when you built freetype, your cross environment is missing libz and libm so the resultant freetype is static linkage only. obj/.lib is missing the libfreetype.dll.a and libfreetype-6.dll files.

---
Can you post output from 'x86_64-w64-mingw32-gcc -v' and 'x86_64-w64-mingw32-ld --verbose'  (just searchdirs section near top of ld output...) Could help to see where your cross system dirs are.

[jamespetts]

Thank you for that: that is most helpful.

The config.mingw64 file was not updated when config.template was updated, so there was no blank FREETYPE_CONFIG option. I have now added this. However, adding this, either with FREETYPE_CONFIG = freetype-config or FREETYPE_CONFIG = (blank) makes no difference.

With VERBOSE = 1, I get the following output:

--- possibly missed edit above:
Can you post output from 'x86_64-w64-mingw32-gcc -v' and 'x86_64-w64-mingw32-ld --verbose'  (just searchdirs section near top of ld output...) Could help to see where your cross system dirs are.

---
verbose output shows indeed -lfreetype is not there. But that would be expected for config.mingw64 with USE_FREETYPE=0, but then the FT_* functions in font.cc shouldn't even be compiled with #ifdef USE_FREETYPE failing...
Are you trying to compile with freetype or not? And I trust you're running 'make CFG=mingw64' to actually use config.mingw64 instead of config.default.
Also, with FREETYPE_CONFIG= make sure no trailing characters....  "=", not "= ".  That got me with OSX and SDL2. grrr.

[jamespetts]

Thank you for that. I had not remembered that I had set USE_FREETYPE=0 earlier. I have now added a manual -lfreetype flag and modified the config file as follows (removing the trailing space after FREETYPE_CONFIG=):

I can confirm that I am issuing the correct env CFG=mingw64 make command.

Having added -lfreetype to LDFLAGS, I get a different set of errors:

To clarify, I am indeed trying to compile with Freetype. I have been able to compile successfully without freetype, but I believe that this loses significant functionality for users of Japanese character sets, so this may be of some importance given the popularity of Simutrans in Japan.

Well, if you want to statically link a library, you need to statically link all its dependents too... and dependents of dependents, and.....  and then all in the correct order too. fun. Hence why config scripts or pkg-config exists.
You're missing libpng.

As an example, on MSYS2 MinGW64, dynamic:

Code Select Expand


$ pkg-config freetype2 --libs
-LC:/msys64/mingw64/lib -lfreetype

Static:

Code Select Expand


$ pkg-config freetype2 --libs --static
-LC:/msys64/mingw64/lib -lfreetype -LC:/msys64/mingw64/lib -lz -lbz2 -lpng16 -lz -lharfbuzz -lm -lusp10 -lgdi32 -lrpcrt4 -ldwrite -LC:/msys64/mingw64/lib -lgraphite2 -lglib-2.0 -lintl -lws2_32 -lole32 -lwinmm -lshlwapi -pthread -lm -LC:/msys64/mingw64/lib -lpcre -lbrotlidec -LC:/msys64/mingw64/lib -lbrotlicommon


You can look in the freetype-2.10.4\builds\unix\freetype2.pc file after building to see what is required. But you have to follow the dependents manually in their pc files. I would expect to find them in /usr/x86_64-w64-mingw32/lib/pkgconfig/*.pc  if available.

This suggests that freetype is having difficulties with a png library, which is odd, since it appears to compile the libraries.

Sort of.

checking for LIBPNG... no
checking for libpng-config... yes

Library configuration:
  libpng:        yes (libpng-config)

Where is freetype2 ./configure finding libpng-config? I have a feeling it's finding the x86_64-linux-gnu version, and not one for x86_64-w64-mingw32. But the headers are likely the same, so you can still build it.
I  presume you don't have a cross version of png installed 'normally' i.e. in /usr/x86_64-w64-mingw32/lib and /usr/x86_64-w64-mingw32/include. else it would say checking for LIBPNG... yes.

The output of the command to which you referred is:

That was actually two commands, compiler, and linker...  but it does show your cross environment prefix is /usr/x86_64-w64-mingw32.
Use that as --prefix when running configures and make installs and you should end up with cross libraries in the 'correct' locations.

I have done some testing of zstd in the new build - I will test and reply to TurfIt's suggestions shortly, but I thought that it would be helpful to record the testing first.

On my system, with the Bridgewater-Brunel saved game from the in-game year 1940, the save took ~36 seconds with zlib and ~23 seconds with zstd with the new build, and ~41 seconds with zlib and the old build (which I suspect has different compression level defaults; I did not change the compression levels).

This suggests that the cross compiled zstd does work effectively to reduce save times - I should be interested to see what effect that this has on the saved games on the server, where saving takes much longer than it does on my system.

Further work on attempting to build with Freetype follows.

I executed the following commands:

root@438242:~/freetype-2.10.4# pkg-config freetype2 --libs --static

root@438242:~/freetype-2.10.4# ./configure --host=x86_64-w64-mingw32 --without-harfbuzz


and generated the following output:

FreeType build system -- automatic system detection

The following settings are used:

  platform                    unix
  compiler                    cc
  configuration directory     ./builds/unix
  configuration rules         ./builds/unix/unix.mk

If this does not correspond to your system or settings please remove the file
`config.mk' from this directory then read the INSTALL file for help.

Otherwise, simply type `make' again to build the library,
or `make refdoc' to build the API reference (this needs Python >= 3.5).

I note the reference to not having libpng properly installed for the cross-compiler; this is indeed the case: when I set this up, I did not realise that standardised directories for cross-compile libraries were a thing, and I still do not know how to go about setting this up. However, what I do notice is that I do not have any manual flags for libraries or includes set up in config.mingw64.

Looking at the /usr/x86_64-w64-mingw32/lib directory, however, there is no libpng.* file there, although I notice that there are pthreads files there, suggesting that I had begun to set up the automatic system somehow in 2017 and not beel able to set this up for the other libraries.

Thus, I am not sure how libpng is being linked. I have a manually created libpng directory containing the following contents:

but none of those appear to be compiled library files. I cannot remember now how I set up libpng to link for Simutrans-Exnteded myself, and I am confused as to where the relevant library files are for linking to Freetype or how to go about finding them.

[prissi]

Cmake does not run on mingw for windows. Does not work. Moreover, Cmake generates a gnu makefile, which we have and which works on most systems. So Cmake seems not the way out (at least until it generates useful Makefiles for Mingw).

But there is the nightly generation on github, using all relevant libraries. Why not download from there? It is just a wget/curl command away ...

The current simutrans nightlies for standard also come from github, since I did not want to bother with zstd cross-compilation on my server. It was way easier to just add curl download command.

Thank you for the suggestion. I have tried to download the Windows Mingw32 SDL build from Github, but it seems to be compiled as dynamically linked, and fails at runtime with an error indicating that I need libstdc++-6.dll (and a lot of other .dlls including for pthreads and zlib).

I suspect that setting up CI to work properly will be at least as much work, if not much more, than setting up the Bridgewater-Brunel server to work. At present, the Bridgewater-Brunel compiling works so long as Freetype is not enabled - and this is not in any event enabled on current nightly builds, so, if I cannot find a solution to this, an option would be just to continue building without Freetype for the time being.

[TurfIt]

I executed the following commands:

root@438242:~/freetype-2.10.4# pkg-config freetype2 --libs --static
-L/usr/local/lib -lfreetype -lz -lpng15 -lm -lz -lm


Almost certainly these are the requirement for your linux system library, not the cross library.  Try "x86_64-w64-mingw32-pkg-config freetype2 --libs --static". I expect you to get either "x86_64-w64-mingw32-pkg-config: command not found" or "Package freetype2 was not found in t....". If the later, good, can work with that. If the former, need to muck with some paths. cross that if needed.

Code Select Expand


root@438242:~/freetype-2.10.4# ./configure --host=x86_64-w64-mingw32 --without-harfbuzz


No. "./configure --prefix=/usr/x86_64-w64-mingw32 --host=x86_64-w64-mingw32  --without-zlib --without-bzip2 --without-png --without-harfbuzz --without-brotli"
Nuke all the optional library dependancies to prevent it finding your linux ones (through config scripts like libpng-config).  Can add back later if desired once stripped basic version running.

and generated the following output:

Please do as it says and install dpkg-dev.  (before running ./configure....)

"make" then generated the following output (truncated to the last section otherwise this would be excessively long):

*** Warning: linker path does not have real file for library -lz.

*** Warning: linker path does not have real file for library -lm.


I do not know whether the -lm and -lz warnings are significant in this context. Attempting to compile the cross-compiled version, I get the following output with the same errors as before:

For libz, why not just install the package for it? "libz-mingw-w64-dev". Then one less library to self compile...
libm. hmmm. ugly. Easiest to just ignore for now since not important for static linking. If you want ability to dynamic link freetype in future, need to solve (something to do with libm.a in mingw being an import library - even static it actually is dynamic against Windows dlls.)

I note the reference to not having libpng properly installed for the cross-compiler; this is indeed the case: when I set this up, I did not realise that standardised directories for cross-compile libraries were a thing, and I still do not know how to go about setting this up.

I don't believe Simutrans is using any functions in freetype2 that require libpng, so skip for now.
So.
1. Install dpkg-dev
2. Install libz-mingw-w64-dev
3. Run "root@438242:~/freetype-2.10.4#./configure --prefix=/usr/x86_64-w64-mingw32 --host=x86_64-w64-mingw32  --without-bzip2 --without-png --without-harfbuzz --without-brotli"
4. Confirm in output:

  Library configuration:
    external zlib: yes (pkg-config)
    bzip2:         no
    libpng:        no
    harfbuzz:      no
    brotli:        no

5. Run "make"
6. Confirm it's only complaining about dynamic libm.   libz should now be ok since you installed it.
7. Run "make install"
8. Confirm you now have "/usr/x86_64-w64-mingw32/lib/libfreetype.a", "/usr/x86_64-w64-mingw32/lib/pkgconfig/freetype2.pc", "/usr/x86_64-w64-mingw32/include/freetype2/*", etc.
9. Test "x86_64-w64-mingw32-pkg-config freetype2 --libs --static". Should now work.
10. Set "FREETYPE_CONFIG=x86_64-w64-mingw32-pkg-config freetype2" in config.mingw64
11. Compile Simutrans.

[jamespetts]

Thank you very much for this: this is most kind.

As to the packages to install - I already have dpkg-dev installed: I confirmed by executing the "apt install dpkg-dev" command, and the returned message indicated that it was installed. I installed libz-mingw-w64-dev.

Executing the command gives the following output:

Despite this, however, making the build works, the server now builds properly with Freetype for cross-compiling.

Thank you very much for all your detailed help - that is very much appreciated indeed. You desrve cake.

For testing purposes, the Freetype enabled build can be downloaded here.


Edit: Ranran - can I check which UI features, if any, need further testing before this is integrated into the master branch? Do you think that anything further needs to be done before integration?

The next step fails as dpkg-dev is not recognised despite the fact that I have it installed:

Apparently fixed in 'mingw-w64 (7.0.0-3) unstable'. Presumably you're running 7.0.0-2.
Workaround is just using pkg-config (i.e. the non cross one) with PKG_CONFIG_LIBDIR set to the cross libs .pcs.
or go back to manually specifying everything.

Installing bzip2 "correctly" and redoing the freetype compile might be desired in case some users wish to use fonts compressed with it...

[prissi]

Mingw cross compile on Debian is somewhat broken, since it claims full C11++ support but chokes on std::thread::... even though there is a header and __Cplusplus is laregr than 2011/3. One either has to use posix threads (and a ton of DLLs) or deliverately detect cross compilation and avoid this. Since this is the most portable way to detect the number of threads for zstd, I stopped cross-compilation and use the mingw builds from github (which are built on windows, where the same code works!)

[Ranran]

I have fixed some bugs and brushed up the GUI.
(1) The construction site was not displayed correctly in hide building mode. This bug can be reproduced on the master branch, but I'm guessing it was probably caused by changing the one way ribi display. I fixed it anyway.

(2) Made the convoy detail dialog (many parts) a new GUI engine. Repaired a broken function. The layout has changed.
The display of the convoy overview can now be switched. This was because the transition of the new GUI engine made it easy to switch this display because it is used in other dialogs, so all I had to do was add a button.
Moved buttons such as sell now and retire to the maintenance tab.
I'm planning to put the class manager inside a tab, but that can take some time.

(3) Brushed up the signalbox list
Added radius display. Added has vacans slot filter. This added two translations.

Ranran - can I check which UI features, if any, need further testing before this is integrated into the master branch?

There are three branches you can test:

(1) accel curve chart
https://github.com/Ranran-the-JuicyPork/simutrans-extended/tree/accel-curve-chart-v2
This adds a physics chart to the convoy detail dialog.
I'm planning to open this dialog from the depot dialog, but it hasn't been implemented yet.

(2) halt detail plus
https://github.com/Ranran-the-JuicyPork/simutrans-extended/tree/halt-detail-plus-v2
This was a lot of work done before the standard merging work. Many improvements have been added to halt detail.
- The third tab is split and route_tab is added.
  You can see a lot of information in debug builds (line speed and preferred line), but it is hidden in release builds.
- Information around the station is added to the first tab.
- Two display options are added to the station dialog. Sort by which line the cargo is waiting for.
  Please note that this is a plan. In short, the preferred line is displayed. If a convoy heading for the same destination arrives first, they may ride on it. This is the same as in the real world.

Note that these patch also adds some translatable terms.


(3) Incorporating from standard (makeobj update - factory location(r8571-) )
https://github.com/Ranran-the-JuicyPork/simutrans-extended/tree/std-makeobj-update

This adds parameters for factory location conditions (forest, river, shore). However, this requires updating the pakset, so I have not confirmed the behavior of the added parameters.

Do you think that anything further needs to be done before integration?

I can't think of anything.



Another big patch from the standard is the climate patch branch.
https://github.com/Ranran-the-JuicyPork/simutrans-extended/tree/std-r9148-climate-patch
I don't think this can be merged right away.
It seems that there is a conflict in the way the river is created and there is a problem with its operation. Can I ask if the river generation method is different between extended and standard?

I also tried sqapi related merging, which seems to be a huge amount of work. Those who are interested in this may be able to proceed with it.

Thank you very much - this is very helpful. I have now incorporated the latest changes from the zstd branch into the master branch: the signal box  list and convoy details improvement were most helpful. I have modified the server's simuconf.tab to switch to zstd level 3 compression when it next restarts, so hopefully to-morrow we will see the effect of zstd on making the server more responsive on loading/saving.

Thank you very much for your excellent work on this to date - it is very much appreciated. The improvement of the GUI between the new version and the old is very great indeed.

As to the other branches, I will test those shortly and revert on this thread when I have done so, but I thought it more important to incorporate the bulk of the changes - especially zstd - into the master branch sooner rather than later now that it is working.

I should note, incidentally, that I have not yet set up 32-bit Windows cross-compile builds. Does anyone use the 32-bit Windows executable any more? It may be worthwhile discontinuing this as a separate build, as many games take more memory than this version is capable of handling in any event.

As to future work, it will be very interesting to see progress on the climates branch. I cannot immediately recall whether there has been an intentional difference in river generation between Extended and Standard; I recall some time ago looking into river generation and testing to ensure that a realistic number of rivers were generated, but I am not sure whether this entailed making some adjustments to the code or simply altering the default river generation parameters. Certainly, if there are any modifications to the Extended river code, I have not made any major changes to it; I cannot immediately recall whether anyone else made changes to this, but I do not recall any major changes of this sort.

As to the scripting API, I can anticipate that this would be a huge amount of work, and, since scripted scenarios are not the paradigm play style for Simutrans-Extended, this is not a priority at present. If anyone is very keen on doing this, it would certainly not hurt to have this integrated, but I suspect that development time is best focussed elsewhere.

After completion of the merging of important features from Standard, the next task, I think, will be the task of reviving and completing the vehicle-management branch, which contains the beginnings of some features that will be very important to game balance. I will need to do the coding for the simulation aspects of this, which will be a substantial task in itself, but the UI will need some consideration. Ves had started to write a UI for this back in 2018 when work was last done on this branch, but this will now be out of date and not compatible with the latest version of the UI code. At least a basic UI will need to be in place for testing purposes (the current state of the code is that I have a lot of memory structures written but no code to do anything with them). Would you be interested in assisting with this? It would be extremely helpful. This will be a project to start early next year, I anticipate, and the first work will be resolving the large numbers of merge conflicts likely to be present, since this branch has not been updated since early 2018. I will need to work on the non-UI aspects of this, but help on the UI aspects (of such UI has has been implemented on this branch so far - I am not sure whether any has been integrated yet) would be appreciated.

[jamespetts]

I am now looking at the first of the new branches, the halt detail branch. First of all, and most importantly, this is an excellent improvement with a great deal of good useful detail and a very clear layout. This is splendid work.

A few very small things: the graphs for "Around passenger demands" seem to overlap with the text in some cases, at least with the "modern" theme. These figures would be easier to read if the thousands were grouped as the numbers can get quite high in some cases.

In at least one instance (Christminster Eastgate on default.sve in Pak128.Britain-Ex), the success rate for commuting trips seems to be >100%, which suggests that there might be a bug in calculating this.

I have corrected a spelling error for the word "preferred". Translation texts will need producing for this branch, and likewise updated help texts.

The default width of this dialogue is often too narrow for all the text that needs to fit into it both horizontally and vertically, especially in the route tab; I am not sure whether this is reasonably easy to change or not. Perhaps the dialogue needs to be resized on opening a new tab to the maximum of the current size or the minimum size necessary to see all the details without scrolling?

Under "Direct routes from here", the names of goods, mail and passengers do not seem to be translated under hl_btn_by_stat... (the rest is truncated).

The text for "transshipment time" seems not to be quite aligned with the "Transfer time" text as though they were all centre aligned: unless there is some good reason for this, either left align or right align would probably be easier to read.

In any event, this is very good work - thank you again for this.

Testing further, the accel-curve-chart-2 branch will not compile when merged with the current master.

The branch updating makeobj I have tested and this appears to work satisfactorily, with forestry industries at least: I have configured these in Pak128.Britain-Ex so that they only spawn in forests, and, testing with a large map, they do indeed only spawn in forests. I have therefore merged this into the master branch.

Thank you very much - this is very helpful. I have now incorporated the latest changes from the zstd branch into the master branch: the signal box  list and convoy details improvement were most helpful. I have modified the server's simuconf.tab to switch to zstd level 3 compression when it next restarts, so hopefully to-morrow we will see the effect of zstd on making the server more responsive on loading/saving.

Thank you very much for your excellent work on this to date - it is very much appreciated. The improvement of the GUI between the new version and the old is very great indeed.

Thank you very much to Prissi, Dwachs & the Standard team for the original changes, Ranran for integrating them into Extended, and James for the code review!:

when it next restarts, so hopefully to-morrow

B-B has not restarted at 0600 for several days now, so it seems unlikely that it will do so tomorrow.... 

As to the other branches, I will test those shortly and revert on this thread when I have done so, but I thought it more important to incorporate the bulk of the changes - especially zstd - into the master branch sooner rather than later now that it is working.

It seems sensible to pause after integrating so many changes since it's reasonable to expect some problems to crop up after such a big merge and more new code makes cause analysis harder. But you knew that already!

I should note, incidentally, that I have not yet set up 32-bit Windows cross-compile builds. Does anyone use the 32-bit Windows executable any more? It may be worthwhile discontinuing this as a separate build, as many games take more memory than this version is capable of handling in any event.

Roboron's statistics for (Standard) Steam users are the most useful data for this decision:



We can see that 32-bit Windows was not in the top 10 used OSes for Standard. I am aware from Discord & Reddit of one Brazilian player who uses the 32-bit Extended executable because he can't get the 64-bit to work on his system. However, I don't think he uses the Nightly Updater and he does have a 64-bit system, so I would not regard his situation as a reason to delay.

Going by these statistics and forum comments, a statically-linked Linux build seems more important than a 32-bit Windows build, since there are definitely users who are unable to play with the dynamically-linked Linux version. (Full disclosure: I am one those unable to use the new Linux version  , though I hope to build a new PC with Ubuntu 20.04 next week).

[jamespetts]

Thank you! I should also, incidentally, mark appreciation, not just of Ranran for all the excellent work in integrating and extending the Standard changes, but the Standard developers who coded them in the first place; they have very significantly improved the UI.

Those statistics are very interesting and useful and confirm that a 32-bit Windows build is not a priority; I shall probably discontinue provindg 32-bit Windows builds as a result of this.

In relation to the server restarting, I have modified the nightly script to try to deal with this problem: hitherto, it had use the nettool shutdown command, but this was prone to timing out if, for example, a player was connecting at the time that the command was sent, so I have reverted to using the external control script to stop the Simutrans-Extended instance to prevent this difficulty from arising.

[Ranran]

Testing further, the accel-curve-chart-2 branch will not compile when merged with the current master.

The cause was that the necessary header file include was removed by the merge.
It would be helpful if you could check it again.

Thank you and well done to Ranran, this is a mostly excellent patch. There are a number of problems which I will report over time, but I will start with the message window. The main problems are:
1. Transparency is not consistent between the top part of the window and the rest of the window.
2. messages are often repeated, including when scrolling the window.
3. coordinate messages cannot be right-clicked to jump
4. message colours are wrong. This includes the 'other players' category, where relevant messages are no longer in player colours.

[Ranran]

Thank you for your feed back.

1. Transparency is not consistent between the top part of the window and the rest of the window.

This may have been caused by code that differs from standard for more than a decade.

2. messages are often repeated, including when scrolling the window.

This seems to reload the message when switching players. At least this behavior can be reproduced with standard, so it is from standard.

3. coordinate messages cannot be right-clicked to jump

That feature was removed in the standard r9347.

4. message colours are wrong. This includes the 'other players' category, where relevant messages are no longer in player colours.

I'm not sure about this. (´・ω・｀)

[freddyhayward]

This seems to reload the message when switching players. At least this behavior can be reproduced with standard, so it is from standard.

No, it repeats constantly without switching players at all.

[Ranran]

Apparently the right-click jump feature was successfully restored. Check the zstd branch.

EDIT:
Duplicate message - It may not be possible to reproduce with the standard that was my misunderstanding.

EDIT2:
I think the duplicate message bug has been fixed by r9500 and r9501. @prissi-Thank you for fixing it.

[prissi]

The right click to pos died rather accidently, I would say. That is in in r9500. And r9501 solved the double entries.

[jamespetts]

Apparently the right-click jump feature was successfully restored. Check the zstd branch.

EDIT:

Thank you for this. Unfortunately, I get compile errors when I merge this with the current master - there seem to be some conflicts somewhere with this.

[jamespetts]

The cause was that the necessary header file include was removed by the merge.
It would be helpful if you could check it again.

Excellent, this now compiles, thank you.

This is interesting and helpful - thank you for this. One thing that I do notice, however, is that the f-v graph has the issue that I reported a while ago in relation to the acceleration curve chart, which is that the last entry is always 0kN both for tractive effort and rolling resistance. This does not make sense, especially for rolling resistance, which increases with speed exponentially. It also means that users have to click on the individual graph nodes to see the right-hand side graph value, which makes the chart harder to use than would be ideal.

Is there any way of truncating the last entry so as for it not to do this?

[Ranran]

I am now looking at the first of the new branches, the halt detail branch.

Thank you for your feedback.

A few very small things: the graphs for "Around passenger demands" seem to overlap with the text in some cases, at least with the "modern" theme. These figures would be easier to read if the thousands were grouped as the numbers can get quite high in some cases.

I didn't consider the font size as it was in the previous specification. It has been fixed.

In at least one instance (Christminster Eastgate on default.sve in Pak128.Britain-Ex), the success rate for commuting trips seems to be >100%, which suggests that there might be a bug in calculating this.

Fixed so that the number of successes does not exceed the generate number in each building.

The default width of this dialogue is often too narrow for all the text that needs to fit into it both horizontally and vertically, especially in the route tab; I am not sure whether this is reasonably easy to change or not. Perhaps the dialogue needs to be resized on opening a new tab to the maximum of the current size or the minimum size necessary to see all the details without scrolling?

(1) I forgot to mention the added three symbols. If the pakset has those symbols, some text will be replaced with the symbols, saving space.
(2) Two type of average speed is only displayed in debug mode. Therefore, the amount of text is smaller in release builds.

The symbol dat is here
https://github.com/Ranran-the-JuicyPork/simutrans-pak128.britain/commit/0610efff425a588ca854ffbf49083947398378d6

Under "Direct routes from here", the names of goods, mail and passengers do not seem to be translated under hl_btn_by_stat... (the rest is truncated).

The width of the two switching buttons is now 1.5 times larger. I also fixed the goods category name that couldn't translate.

The text for "transshipment time" seems not to be quite aligned with the "Transfer time" text as though they were all centre aligned: unless there is some good reason for this, either left align or right align would probably be easier to read.

I think this has been fixed.

Is there any way of truncating the last entry so as for it not to do this?

I think it is difficult in current systems. For example, if the maximum speed is 409km / h, the graph will never take an integer in the middle unless an array of 409 is automatically generated.
That is, we need a system that creates arrays and graphs in a fluid manner.
Or set a sharp point such as 410, then move the axis slightly forward at the end, set the end point of the graph there, draw a line and truncate the rest.
This also requires modification of the code.

[wlindley]

The text below each of the convoys on the Line Management dialogue seems to be missing?  Makes it quite difficult to see which convoy is profitable or loaded.

Also not sure what I have to do so to that cl_btn_general gets translated...

[Phystam]

This is a small report and is not a bug. After incorporating standard features, the Extended revision has not been shown on the top but the Standard revision.

[freddyhayward]

Feel free to split this into a new thread if necessary. Petrol vehicles are no longer available at any time on any map from any type of depot, including road depots and aircraft hangars.

Thank you for your report. I think I've fixed it. Please confirm.
