Replace mkfiles.pl with a CMake build system. This brings various concrete advantages over the previous system: - consistent support for out-of-tree builds on all platforms - more thorough support for Visual Studio IDE project files - support for Ninja-based builds, which is particularly useful on Windows where the alternative nmake has no parallel option - a really simple set of build instructions that work the same way on all the major platforms (look how much shorter README is!) - better decoupling of the project configuration from the toolchain configuration, so that my Windows cross-building doesn't need (much) special treatment in CMakeLists.txt - configure-time tests on Windows as well as Linux, so that a lot of ad-hoc #ifdefs second-guessing a particular feature's presence from the compiler version can now be replaced by tests of the feature itself Also some longer-term software-engineering advantages: - other people have actually heard of CMake, so they'll be able to produce patches to the new build setup more easily - unlike the old mkfiles.pl, CMake is not my personal problem to maintain - most importantly, mkfiles.pl was just a horrible pile of unmaintainable cruft, which even I found it painful to make changes to or to use, and desperately needed throwing in the bin. I've already thrown away all the variants of it I had in other projects of mine, and was only delaying this one so we could make the 0.75 release branch first. This change comes with a noticeable build-level restructuring. The previous Recipe worked by compiling every object file exactly once, and then making each executable by linking a precisely specified subset of the same object files. But in CMake, that's not the natural way to work - if you write the obvious command that puts the same source file into two executable targets, CMake generates a makefile that compiles it once per target. That can be an advantage, because it gives you the freedom to compile it differently in each case (e.g. with a #define telling it which program it's part of). But in a project that has many executable targets and had carefully contrived to _never_ need to build any module more than once, all it does is bloat the build time pointlessly! To avoid slowing down the build by a large factor, I've put most of the modules of the code base into a collection of static libraries organised vaguely thematically (SSH, other backends, crypto, network, ...). That means all those modules can still be compiled just once each, because once each library is built it's reused unchanged for all the executable targets. One upside of this library-based structure is that now I don't have to manually specify exactly which objects go into which programs any more - it's enough to specify which libraries are needed, and the linker will figure out the fine detail automatically. So there's less maintenance to do in CMakeLists.txt when the source code changes. But that reorganisation also adds fragility, because of the trad Unix linker semantics of walking along the library list once each, so that cyclic references between your libraries will provoke link errors. The current setup builds successfully, but I suspect it only just manages it. (In particular, I've found that MinGW is the most finicky on this score of the Windows compilers I've tried building with. So I've included a MinGW test build in the new-look Buildscr, because otherwise I think there'd be a significant risk of introducing MinGW-only build failures due to library search order, which wasn't a risk in the previous library-free build organisation.) In the longer term I hope to be able to reduce the risk of that, via gradual reorganisation (in particular, breaking up too-monolithic modules, to reduce the risk of knock-on references when you included a module for function A and it also contains function B with an unsatisfied dependency you didn't really need). Ideally I want to reach a state in which the libraries all have sensibly described purposes, a clearly documented (partial) order in which they're permitted to depend on each other, and a specification of what stubs you have to put where if you're leaving one of them out (e.g. nocrypto) and what callbacks you have to define in your non-library objects to satisfy dependencies from things low in the stack (e.g. out_of_memory()). One thing that's gone completely missing in this migration, unfortunately, is the unfinished MacOS port linked against Quartz GTK. That's because it turned out that I can't currently build it myself, on my own Mac: my previous installation of GTK had bit-rotted as a side effect of an Xcode upgrade, and I haven't yet been able to persuade jhbuild to make me a new one. So I can't even build the MacOS port with the _old_ makefiles, and hence, I have no way of checking that the new ones also work. I hope to bring that port back to life at some point, but I don't want it to block the rest of this change.

add_sources_from_current_dir(utils
New library-style 'utils' subdirectories. Now that the new CMake build system is encouraging us to lay out the code like a set of libraries, it seems like a good idea to make them look more _like_ libraries, by putting things into separate modules as far as possible. This fixes several previous annoyances in which you had to link against some object in order to get a function you needed, but that object also contained other functions you didn't need which included link-time symbol references you didn't want to have to deal with. The usual offender was subsidiary supporting programs including misc.c for some innocuous function and then finding they had to deal with the requirements of buildinfo(). This big reorganisation introduces three new subdirectories called 'utils', one at the top level and one in each platform subdir. In each case, the directory contains basically the same files that were previously placed in the 'utils' build-time library, except that the ones that were extremely miscellaneous (misc.c, utils.c, uxmisc.c, winmisc.c, winmiscs.c, winutils.c) have been split up into much smaller pieces.

Replace mkfiles.pl with a CMake build system. This brings various concrete advantages over the previous system: - consistent support for out-of-tree builds on all platforms - more thorough support for Visual Studio IDE project files - support for Ninja-based builds, which is particularly useful on Windows where the alternative nmake has no parallel option - a really simple set of build instructions that work the same way on all the major platforms (look how much shorter README is!) - better decoupling of the project configuration from the toolchain configuration, so that my Windows cross-building doesn't need (much) special treatment in CMakeLists.txt - configure-time tests on Windows as well as Linux, so that a lot of ad-hoc #ifdefs second-guessing a particular feature's presence from the compiler version can now be replaced by tests of the feature itself Also some longer-term software-engineering advantages: - other people have actually heard of CMake, so they'll be able to produce patches to the new build setup more easily - unlike the old mkfiles.pl, CMake is not my personal problem to maintain - most importantly, mkfiles.pl was just a horrible pile of unmaintainable cruft, which even I found it painful to make changes to or to use, and desperately needed throwing in the bin. I've already thrown away all the variants of it I had in other projects of mine, and was only delaying this one so we could make the 0.75 release branch first. This change comes with a noticeable build-level restructuring. The previous Recipe worked by compiling every object file exactly once, and then making each executable by linking a precisely specified subset of the same object files. But in CMake, that's not the natural way to work - if you write the obvious command that puts the same source file into two executable targets, CMake generates a makefile that compiles it once per target. That can be an advantage, because it gives you the freedom to compile it differently in each case (e.g. with a #define telling it which program it's part of). But in a project that has many executable targets and had carefully contrived to _never_ need to build any module more than once, all it does is bloat the build time pointlessly! To avoid slowing down the build by a large factor, I've put most of the modules of the code base into a collection of static libraries organised vaguely thematically (SSH, other backends, crypto, network, ...). That means all those modules can still be compiled just once each, because once each library is built it's reused unchanged for all the executable targets. One upside of this library-based structure is that now I don't have to manually specify exactly which objects go into which programs any more - it's enough to specify which libraries are needed, and the linker will figure out the fine detail automatically. So there's less maintenance to do in CMakeLists.txt when the source code changes. But that reorganisation also adds fragility, because of the trad Unix linker semantics of walking along the library list once each, so that cyclic references between your libraries will provoke link errors. The current setup builds successfully, but I suspect it only just manages it. (In particular, I've found that MinGW is the most finicky on this score of the Windows compilers I've tried building with. So I've included a MinGW test build in the new-look Buildscr, because otherwise I think there'd be a significant risk of introducing MinGW-only build failures due to library search order, which wasn't a risk in the previous library-free build organisation.) In the longer term I hope to be able to reduce the risk of that, via gradual reorganisation (in particular, breaking up too-monolithic modules, to reduce the risk of knock-on references when you included a module for function A and it also contains function B with an unsatisfied dependency you didn't really need). Ideally I want to reach a state in which the libraries all have sensibly described purposes, a clearly documented (partial) order in which they're permitted to depend on each other, and a specification of what stubs you have to put where if you're leaving one of them out (e.g. nocrypto) and what callbacks you have to define in your non-library objects to satisfy dependencies from things low in the stack (e.g. out_of_memory()). One thing that's gone completely missing in this migration, unfortunately, is the unfinished MacOS port linked against Quartz GTK. That's because it turned out that I can't currently build it myself, on my own Mac: my previous installation of GTK had bit-rotted as a side effect of an Xcode upgrade, and I haven't yet been able to persuade jhbuild to make me a new one. So I can't even build the MacOS port with the _old_ makefiles, and hence, I have no way of checking that the new ones also work. I hope to bring that port back to life at some point, but I don't want it to block the rest of this change.

Move some add_executable() calls to top-level CMakeLists. Now that the main source file of Plink in each platform directory has the same name, we can put centralise the main definition of the program in the main CMakeLists.txt, and in the platform directory, just add the few extra modules needed to clear up platform-specific details. The same goes for psocks. And PSCP and PSFTP could have been moved to the top level already - I just hadn't done it in the initial setup.

Also, as with my other recent renaming sprees, I've taken the opportunity to expand and clarify some of the names so that they're not such cryptic abbreviations.

Replace mkfiles.pl with a CMake build system. This brings various concrete advantages over the previous system: - consistent support for out-of-tree builds on all platforms - more thorough support for Visual Studio IDE project files - support for Ninja-based builds, which is particularly useful on Windows where the alternative nmake has no parallel option - a really simple set of build instructions that work the same way on all the major platforms (look how much shorter README is!) - better decoupling of the project configuration from the toolchain configuration, so that my Windows cross-building doesn't need (much) special treatment in CMakeLists.txt - configure-time tests on Windows as well as Linux, so that a lot of ad-hoc #ifdefs second-guessing a particular feature's presence from the compiler version can now be replaced by tests of the feature itself Also some longer-term software-engineering advantages: - other people have actually heard of CMake, so they'll be able to produce patches to the new build setup more easily - unlike the old mkfiles.pl, CMake is not my personal problem to maintain - most importantly, mkfiles.pl was just a horrible pile of unmaintainable cruft, which even I found it painful to make changes to or to use, and desperately needed throwing in the bin. I've already thrown away all the variants of it I had in other projects of mine, and was only delaying this one so we could make the 0.75 release branch first. This change comes with a noticeable build-level restructuring. The previous Recipe worked by compiling every object file exactly once, and then making each executable by linking a precisely specified subset of the same object files. But in CMake, that's not the natural way to work - if you write the obvious command that puts the same source file into two executable targets, CMake generates a makefile that compiles it once per target. That can be an advantage, because it gives you the freedom to compile it differently in each case (e.g. with a #define telling it which program it's part of). But in a project that has many executable targets and had carefully contrived to _never_ need to build any module more than once, all it does is bloat the build time pointlessly! To avoid slowing down the build by a large factor, I've put most of the modules of the code base into a collection of static libraries organised vaguely thematically (SSH, other backends, crypto, network, ...). That means all those modules can still be compiled just once each, because once each library is built it's reused unchanged for all the executable targets. One upside of this library-based structure is that now I don't have to manually specify exactly which objects go into which programs any more - it's enough to specify which libraries are needed, and the linker will figure out the fine detail automatically. So there's less maintenance to do in CMakeLists.txt when the source code changes. But that reorganisation also adds fragility, because of the trad Unix linker semantics of walking along the library list once each, so that cyclic references between your libraries will provoke link errors. The current setup builds successfully, but I suspect it only just manages it. (In particular, I've found that MinGW is the most finicky on this score of the Windows compilers I've tried building with. So I've included a MinGW test build in the new-look Buildscr, because otherwise I think there'd be a significant risk of introducing MinGW-only build failures due to library search order, which wasn't a risk in the previous library-free build organisation.) In the longer term I hope to be able to reduce the risk of that, via gradual reorganisation (in particular, breaking up too-monolithic modules, to reduce the risk of knock-on references when you included a module for function A and it also contains function B with an unsatisfied dependency you didn't really need). Ideally I want to reach a state in which the libraries all have sensibly described purposes, a clearly documented (partial) order in which they're permitted to depend on each other, and a specification of what stubs you have to put where if you're leaving one of them out (e.g. nocrypto) and what callbacks you have to define in your non-library objects to satisfy dependencies from things low in the stack (e.g. out_of_memory()). One thing that's gone completely missing in this migration, unfortunately, is the unfinished MacOS port linked against Quartz GTK. That's because it turned out that I can't currently build it myself, on my own Mac: my previous installation of GTK had bit-rotted as a side effect of an Xcode upgrade, and I haven't yet been able to persuade jhbuild to make me a new one. So I can't even build the MacOS port with the _old_ makefiles, and hence, I have no way of checking that the new ones also work. I hope to bring that port back to life at some point, but I don't want it to block the rest of this change.

New application: a Windows version of 'pterm'! This fulfills our long-standing Mayhem-difficulty wishlist item 'win-command-prompt': this is a Windows pterm in the sense that when you run it you get a local cmd.exe running inside a PuTTY-style window. Advantages of this: you get the same free choice of fonts as PuTTY has (no restriction to a strange subset of the system's available fonts); you get the same copy-paste gestures as PuTTY (no mental gear-shifting when you have command prompts and SSH sessions open on the same desktop); you get scrollback with the PuTTY semantics (scrolling to the bottom gets you to where the action is, as opposed to the way you could accidentally find yourself 500 lines past the end of the action in a real console). 'win-command-prompt' was at Mayhem difficulty ('Probably impossible') basically on the grounds that with Windows's old APIs for accessing the contents of consoles, there was no way I could find to get this to work sensibly. What was needed to make it feasible was a major piece of re-engineering work inside Windows itself. But, of course, that's exactly what happened! In 2019, the new ConPTY API arrived, which lets you create an object that behaves like a Windows console at one end, and round the back, emits a stream of VT-style escape sequences as the screen contents evolve, and accepts a VT-style input stream in return which it will parse function and arrow keys out of in the usual way. So now it's actually _easy_ to get this to basically work. The new backend, in conpty.c, has to do a handful of magic Windows API calls to set up the pseudo-console and its feeder pipes and start a subprocess running in it, a further magic call every time the PuTTY window is resized, and detect the end of the session by watching for the subprocess terminating. But apart from that, all it has to do is pass data back and forth unmodified between those pipes and the backend's associated Seat! That said, this is new and experimental, and there will undoubtedly be issues. One that I already know about is that you can't copy and paste a word that has wrapped between lines without getting an annoying newline in the middle of it. As far as I can see this is a fundamental limitation: the ConPTY system sends the _same_ escape sequence stream for a line that wrapped as it would send for a line that had a logical \n at what would have been the wrap point. Probably the best we can do to mitigate this is to adopt a different heuristic for newline elision that's right more often than it's wrong. For the moment, that experimental-ness is indicated by the fact that Buildscr will build, sign and deliver a copy of pterm.exe for each flavour of Windows, but won't include it in the .zip file or in the installer. (In fact, that puts it in exactly the same ad-hoc category as PuTTYtel, although for completely different reasons.)
