terminfo: install to $datadir/foot/terminfo by default, append to TERMINFO_DIRS As of 2021-07-31, ncurses ships its own version of foot’s terminfo. Since: * It doesn’t have the non-standard Sync,Tc,setrgbf,setrgbb capabilities. * It doesn’t set hs,fsl,dsl (statusbar). * We want to be able to update our termminfo without waiting for an ncurses release. * Foot should be installable and usable on Linux systems that doesn’t have the latest ncurses. we still want to ship our own version. We can however not install it to the default terminfo location (e.g. /usr/share/terminfo), since it will collide with the ncurses provided files. Our options are to either rename our terminfo to something else, or to keep the name, but install our terminfo files somewhere else. The first option would be the easy one. However, I think it makes sense to use the same name. For example, a user that SSH’s into a remote system that does *not* have our own version installed, but *does* have the ncurses one, will gracefully fall back to that one, which is better than manually having to set e.g. TERM=xterm-256color. Now, if we want to use the same name, we need to install it somewhere else. But where? And how do we ensure our version is preferred over the ncurses one? I opted to $datadir/foot/terminfo (e.g. /usr/share/foot/terminfo) by default. It makes it namespaced to foot (i.e. we’re not introducing a new “standard” terminfo location), thus guaranteeing it wont collide with ncurses. To enable applications to find it, we export TERMINFO_DIRS. This is a list of *additional* directories to search for terminfo files. If it’s already defined, we *append* to it. The nice thing with this is, if there’s no terminfo in that location (e.g. when you SSH into a remote), the default terminfo location is *also* searched. But only *after* having searched through TERMINFO_DIRS. In short: our version is preferred, but the ncurses one (or an older version of our terminfo package!) will be used if ours cannot be found. To enable packagers full control over the new behavior, the existing meson command line options have been modified, and a new option added: -Dterminfo=disabled|enabled|auto: *build* and *install* the terminfo files. -Dcustom-terminfo-install-location=<path>: *where* the terminfo files are expected to be found. This *needs* to be set *even* if -Dterminfo=disabled. For example, if the packaging script builds and packages the terminfo files separate from the regular foot build. The path is *relative to $prefix*, and defaults to $datadir/foot/terminfo. This is the value that will be appended to TERMINFO_DIRS. Note that you can set it to ‘no’, in which case foot will *not* set/modify TERMINFO_DIRS. Only do this if you don’t intend to package foot’s terminfo files at all (i.e. you plan on using the ncurses ones only). -Ddefault-terminfo=foot. Allows overriding the default TERM value. This should only be changed if the target platform doesn’t support terminfo files. Closes #671

composed: store compose chains in a binary search tree The previous implementation stored compose chains in a dynamically allocated array. Adding a chain was easy: resize the array and append the new chain at the end. Looking up a compose chain given a compose chain key/index was also easy: just index into the array. However, searching for a pre-existing chain given a codepoint sequence was very slow. Since the array wasn’t sorted, we typically had to scan through the entire array, just to realize that there is no pre-existing chain, and that we need to add a new one. Since this happens for *each* codepoint in a grapheme cluster, things quickly became really slow. Things were ok:ish as long as the compose chain struct was small, as that made it possible to hold all the chains in the cache. Once the number of chains reached a certain point, or when we were forced to bump maximum number of allowed codepoints in a chain, we started thrashing the cache and things got much much worse. So what can we do? We can’t sort the array, because a) that would invalidate all existing chain keys in the grid (and iterating the entire scrollback and updating compose keys is *not* an option). b) inserting a chain becomes slow as we need to first find _where_ to insert it, and then memmove() the rest of the array. This patch uses a binary search tree to store the chains instead of a simple array. The tree is sorted on a “key”, which is the XOR of all codepoints, truncated to the CELL_COMB_CHARS_HI-CELL_COMB_CHARS_LO range. The grid now stores CELL_COMB_CHARS_LO+key, instead of CELL_COMB_CHARS_LO+index. Since the key is truncated, collisions may occur. This is handled by incrementing the key by 1. Lookup is of course slower than before, O(log n) instead of O(1). Insertion is slightly slower as well: technically it’s O(log n) instead of O(1). However, we also need to take into account the re-allocating the array will occasionally force a full copy of the array when it cannot simply be growed. But finding a pre-existing chain is now *much* faster: O(log n) instead of O(n). In most cases, the first lookup will either succeed (return a true match), or fail (return NULL). However, since key collisions are possible, it may also return false matches. This means we need to verify the contents of the chain before deciding to use it instead of inserting a new chain. But remember that this comparison was being done for each and every chain in the previous implementation. With lookups being much faster, and in particular, no longer requiring us to check the chain contents for every singlec chain, we can now use a dynamically allocated ‘chars’ array in the chain. This was previously a hardcoded array of 10 chars. Using a dynamic allocated array means looking in the array is slower, since we now need two loads: one to load the pointer, and a second to load _from_ the pointer. As a result, the base size of a compose chain (i.e. an “empty” chain) has now been reduced from 48 bytes to 32. A chain with two codepoints is 40 bytes. This means we have up to 4 codepoints while still using less, or the same amount, of memory as before. Furthermore, the Unicode random test (i.e. write random “unicode” chars) is now **faster** than current master (i.e. before text-shaping support was added), **with** test-shaping enabled. With text-shaping disabled, we’re _even_ faster.

key-binding: new API, for handling sets of key bindings Up until now, our Wayland seats have been tracking key bindings. This makes sense, since the seat’s keymap determines how the key bindings are resolved. However, tying bindings to the seat/keymap alone isn’t enough, since we also depend on the current configuration (i.e. user settings) when resolving a key binding. This means configurations that doesn’t match the wayland object’s configuration, currently don’t resolve key bindings correctly. This applies to footclients where the user has overridden key bindings on the command line (e.g. --override key-bindings.foo=bar). Thus, to correctly resolve key bindings, each set of key bindings must be tied *both* to a seat/keymap, *and* a configuration. This patch introduces a key-binding manager, with an API to add/remove/lookup, and load/unload keymaps from sets of key bindings. In the API, sets are tied to a seat and terminal instance, since this makes the most sense (we need to instantiate, or incref a set whenever a new terminal instance is created). Internally, the set is tied to a seat and the terminal’s configuration. Sets are *added* when a new seat is added, and when a new terminal instance is created. Since there can only be one instance of each seat, sets are always removed when a seat is removed. Terminals on the other hand can re-use the same configuration (and typically do). Thus, sets ref-count the configuration. In other words, when instantiating a new terminal, we may not have to instantiate a new set of key bindings, but can often be incref:ed instead. Whenever the keymap changes on a seat, all key bindings sets associated with that seat reloads (re-resolves) their key bindings. Closes #931

terminfo: install to $datadir/foot/terminfo by default, append to TERMINFO_DIRS As of 2021-07-31, ncurses ships its own version of foot’s terminfo. Since: * It doesn’t have the non-standard Sync,Tc,setrgbf,setrgbb capabilities. * It doesn’t set hs,fsl,dsl (statusbar). * We want to be able to update our termminfo without waiting for an ncurses release. * Foot should be installable and usable on Linux systems that doesn’t have the latest ncurses. we still want to ship our own version. We can however not install it to the default terminfo location (e.g. /usr/share/terminfo), since it will collide with the ncurses provided files. Our options are to either rename our terminfo to something else, or to keep the name, but install our terminfo files somewhere else. The first option would be the easy one. However, I think it makes sense to use the same name. For example, a user that SSH’s into a remote system that does *not* have our own version installed, but *does* have the ncurses one, will gracefully fall back to that one, which is better than manually having to set e.g. TERM=xterm-256color. Now, if we want to use the same name, we need to install it somewhere else. But where? And how do we ensure our version is preferred over the ncurses one? I opted to $datadir/foot/terminfo (e.g. /usr/share/foot/terminfo) by default. It makes it namespaced to foot (i.e. we’re not introducing a new “standard” terminfo location), thus guaranteeing it wont collide with ncurses. To enable applications to find it, we export TERMINFO_DIRS. This is a list of *additional* directories to search for terminfo files. If it’s already defined, we *append* to it. The nice thing with this is, if there’s no terminfo in that location (e.g. when you SSH into a remote), the default terminfo location is *also* searched. But only *after* having searched through TERMINFO_DIRS. In short: our version is preferred, but the ncurses one (or an older version of our terminfo package!) will be used if ours cannot be found. To enable packagers full control over the new behavior, the existing meson command line options have been modified, and a new option added: -Dterminfo=disabled|enabled|auto: *build* and *install* the terminfo files. -Dcustom-terminfo-install-location=<path>: *where* the terminfo files are expected to be found. This *needs* to be set *even* if -Dterminfo=disabled. For example, if the packaging script builds and packages the terminfo files separate from the regular foot build. The path is *relative to $prefix*, and defaults to $datadir/foot/terminfo. This is the value that will be appended to TERMINFO_DIRS. Note that you can set it to ‘no’, in which case foot will *not* set/modify TERMINFO_DIRS. Only do this if you don’t intend to package foot’s terminfo files at all (i.e. you plan on using the ncurses ones only). -Ddefault-terminfo=foot. Allows overriding the default TERM value. This should only be changed if the target platform doesn’t support terminfo files. Closes #671

It makes it namespaced to foot (i.e. we’re not introducing a new “standard” terminfo location), thus guaranteeing it wont collide with ncurses. To enable applications to find it, we export TERMINFO_DIRS. This is a list of *additional* directories to search for terminfo files. If it’s already defined, we *append* to it. The nice thing with this is, if there’s no terminfo in that location (e.g. when you SSH into a remote), the default terminfo location is *also* searched. But only *after* having searched through TERMINFO_DIRS. In short: our version is preferred, but the ncurses one (or an older version of our terminfo package!) will be used if ours cannot be found. To enable packagers full control over the new behavior, the existing meson command line options have been modified, and a new option added: -Dterminfo=disabled|enabled|auto: *build* and *install* the terminfo files. -Dcustom-terminfo-install-location=<path>: *where* the terminfo files are expected to be found. This *needs* to be set *even* if -Dterminfo=disabled. For example, if the packaging script builds and packages the terminfo files separate from the regular foot build. The path is *relative to $prefix*, and defaults to $datadir/foot/terminfo. This is the value that will be appended to TERMINFO_DIRS. Note that you can set it to ‘no’, in which case foot will *not* set/modify TERMINFO_DIRS. Only do this if you don’t intend to package foot’s terminfo files at all (i.e. you plan on using the ncurses ones only). -Ddefault-terminfo=foot. Allows overriding the default TERM value. This should only be changed if the target platform doesn’t support terminfo files. Closes #671

terminfo: install to $datadir/foot/terminfo by default, append to TERMINFO_DIRS As of 2021-07-31, ncurses ships its own version of foot’s terminfo. Since: * It doesn’t have the non-standard Sync,Tc,setrgbf,setrgbb capabilities. * It doesn’t set hs,fsl,dsl (statusbar). * We want to be able to update our termminfo without waiting for an ncurses release. * Foot should be installable and usable on Linux systems that doesn’t have the latest ncurses. we still want to ship our own version. We can however not install it to the default terminfo location (e.g. /usr/share/terminfo), since it will collide with the ncurses provided files. Our options are to either rename our terminfo to something else, or to keep the name, but install our terminfo files somewhere else. The first option would be the easy one. However, I think it makes sense to use the same name. For example, a user that SSH’s into a remote system that does *not* have our own version installed, but *does* have the ncurses one, will gracefully fall back to that one, which is better than manually having to set e.g. TERM=xterm-256color.
