2022-11-19Use spawn_async instead of spawn_syncWolfgang Müller-7/+17
The 'spawn_sync' function has been deprecated for a very long time now, but we could never use its intended replacement as its Vala bindings were broken [1]. The underlying problem had been identified in [2] a while ago, but has only been recently fixed in [3] and is now available in Vala's 0.56 branch. Since we rely on the child PID as a fallback for opinionated users or shells that are unaware of OSC 7, we have to pass a callback function to the 'spawn_async' call so we can capture the PID which is no longer supplied by the method itself. [1] https://gitlab.gnome.org/GNOME/vte/issues/227 [2] https://gitlab.gnome.org/GNOME/vala/-/issues/721 [3] https://gitlab.gnome.org/GNOME/vala/-/commit/f058e9e828f494ebf8d60cabff7999f219048623
2022-02-27Add support for rtmp:// URLsJuhani Krekelä-1/+1
2021-11-27Allow user to turn OSC 7 offJuhani Krekelä-3/+6
Currently weltschmerz prefers working directory information obtained from OSC 7 to that from procfs. If a user has not configured their shell to emit OSC 7 escapes, the OSC 7 path may be out of date. Additionally some users want only their shell to change the terminal's conception of working directory, which is a behaviour better matched by the procfs based working directory detection. This change allows OSC 7 based working directory detection to be turned off. The default remains to check OSC 7 first and then fall back to procfs if there is not valid local path set with OSC 7. The reason for turning OSC 7 off entirely instead of inverting the order procfs and OSC 7 are checked in is that procfs based detection should never fail under normal usage on systems that support it.
2021-11-27Make configuration object accessible outside of load_configJuhani Krekelä-1/+2
Currently the configuration object is located in the function level scope of load_config() and deleted once the function exits. Any flags that control the program behaviour must therefore be copied into separate variables, which pollutes the the upper level namespace. This change keeps the configuration object around after load_config() exits and makes it accessible by other functions from the shared namespace. An upcoming change needs this access.
2021-11-27Add procfs fallback for figuring out the cwdJuhani Krekelä-6/+15
Opening a terminal or file manager window requires weltschmerz to know the current working directory. At the moment weltschmerz relies on the application being run in the terminal to generate OSC 7 codes that specify the path. However, OSC 7 is not yet widely supported by default, and the VTE terminal emulation layer, which manages the OSC 7 path state for weltschmerz, will overwrite local paths with ones that point to a remote computer if an OSC 7 enabled application is run under ssh. This change adds a fallback that uses the symlink to current working directory located at /proc/<child pid>/cwd. On Linux this method should always work and was how these features were implemented before adoption of OSC 7. The procfs method is used as a fallback instead of the primary method since it can only see the working directory changes of the direct child process.
2021-11-27Don't consider punctuation as part of the URLJuhani Krekelä-1/+1
We currently consider periods, commas, colons, semicolons, exclamation points and question marks following a URL as part of it. While ending a URL with these characters is technically speaking valid, more commonly they are a result of people ending a clause with a URL. Let's ignore such characters if they are present at the very end of a URL. Make sure to still match them, however, if any non-punctuation characters follow. This way, almost all actual usage of punctuation within URLs is unaffected.
2021-11-27Add ability to specify additional URI handlersJuhani Krekelä-0/+40
This commit adds a new section, open-with, to the configuration file. The options specified there will be added as "Open with …" menu items in the URI context menu. This is to make it easier to perform other actions on the URI than opening it in the system default browser; a user might for example add another browser, media player, or a script that preprocesses the URI before opening it.
2021-07-24Move spawning a subprocess into its own functionJuhani Krekelä-7/+10
The upcoming "Open with …" feature will need to spawn subprocesses in very similar way as open_terminal(). Moving process creation to its own function allows the same logic to be reused.
2021-07-24Unify context menus for URLs and OSC 8 hyperlinksJuhani Krekelä-8/+4
Currently weltschmerz has separate context menus for the two types of URIs one can interact with, even though they contain the same option with only a little different phrasing. This makes both use the same context menu, and standardizes terminology to "URI". This unification is in preparation for an upcoming "Open with …" feature which will programmatically add items to context menu for URIs. Without this, we would need to duplicate logic for each of the separate menus.
2021-07-09Add support for gopher:// URLsJuhani Krekelä-1/+1
2021-07-09Improve URL matchingJuhani Krekelä-1/+1
Currently the weltschmerz URL regex does not match URLs with quotes or parentheses, considering the URL to end when one is encountered. On the other hand, if a URL is surrounded by angle brackets it includes the closing '>' in the URL match. Additionally, the regex allows URL to contain a space if and only if it is the second character of the host component of the URL. Most of this appears to be down to bugs in the regex as it is currently written. This rewrites the regex to be cleaner and easier to read, while maintaining the intended logic of the original.
2021-07-02Only allow opening local directoriesJuhani Krekelä-2/+11
The proposed OSC 7 specification mandates [1] that the file:// URI includes the hostname, so that the terminal emulator can ignore remotely used programs' attempts to set the current working directory. However, VTE does not check the hostname component, and neither does launch_default_for_uri. Thus currently if one tries to open directory after running a remote program that used OSC 7, weltschmerz tries to open a file manager pointing at corresponding path on the local computer. weltschmerz already contains a function that checks the URI kept by VTE and returns the path only if it is on the local computer. This commit changes open_directory() to first use that, and then create a new local file:// URI based on it, unifying the behaviour of 'Open directory' and 'Open terminal'.

2021-06-27Mark messages for translationWolfgang Müller-2/+2
With the translation infrastructure now in place, make sure to mark every user-bound message for translation. All but one of the strings in terminal.ui are already marked. This commit marks all remaining messages in the Vala code as well as the missing one from terminal.ui. One of the messages in terminal.ui is a sample error message for the infobar label. Since this message will never be visible to the user (the code overrides the label's contents with any relevant warning messages), we do not need to keep it marked. Finally, give translators ample context for what they will have to translate and fix a small inconsistency with the capitalization of warning messages in configreader.vala.
2021-06-26Add feature to open a new terminalJuhani Krekelä-0/+49
Add ability to open a new weltschmerz terminal, either from context menu or with a key combination. The new terminal is opened in the directory indicated with OSC 7, allowing quickly opening additional terminals while working. Preferably this would launch the user's preferred terminal, as defined in per-user settings, but this is not possible with glib[1]. For this reason the option always launches another weltschmerz. weltschmerz is launched using bare Process.spawn_async() on the name of the program as defined in weltschmerz.vala. We considered using the AppInfo database to retrieve the name of executable instead, but as there is no way to query the database for terminal emulators we would have to go through every single program installed on the computer and try to find one called weltschmerz. As the change would merely replace the requirement of having weltschmerz in PATH with the requirement of having a .desktop file with the name in one of the standardized locations, this would not be worth it.

2021-06-25Copy URLs to the PRIMARY selection as wellWolfgang Müller-0/+4
Currently, weltschmerz only copies URLs to GTK's default clipboard. This is defined to be CLIPBOARD, leaving the PRIMARY selection unchanged. Since all other normal copy/paste operations start with making a selection and therefore set PRIMARY, make sure to also set the PRIMARY selection when copying a URL. This brings weltschmerz in line with how other GTK apps behave.
2021-06-25Use fallback 'html' value for vte_copy() in vte_key_press()Wolfgang Müller-1/+1
No functional change, since vte_copy() defaults to false here. This seems to be a remnant of when vte_copy() required specifying the 'html' argument.
2021-06-23Define a reasonable minimum sizeWolfgang Müller-4/+6
Previously, in commit c49fbfb (Set minimum width and height in window geometry, 2021-06-17), we set the minimum size of the window to one cell. We do not yet include our fixes from 89f8571 (Calculate base_width dynamically, 2021-06-18) and so do not account for the scrollbar when setting the minimum size hints. A minimum size of one cell can lead to issues like [1] when resizing aggressively. A fix for this has been committed in [2], but not yet merged to any release branch. Setting the minimum size to larger values seems to work around this problem. Therefore, define a minimum window size of 28 x 3 cells - just big enough to still fit the search overlay. Make sure to include base_height and base_width so that the right size will be reported to the window manager. [1] https://gitlab.gnome.org/GNOME/vte/-/issues/340 [2] https://gitlab.gnome.org/GNOME/vte/-/commit/b333d66879963637099dc0bc5a702f50f34da67e
2021-06-19Clean up and slightly reorganize load_config()Wolfgang Müller-3/+1
2021-06-19Calculate base_width dynamicallyWolfgang Müller-1/+10
weltschmerz sets window geometry hints to indicate how the terminal window is to be sized and resized. New sizes are always kept at a multiple of the character width and height. Effectively, this ensures that terminal windows never have "negative space" that is not used for any terminal output. In order to account for padding and non-terminal widgets, one may specify base_height and base_width. These values indicate how much space to add in a final step, after the character width and heights have been multiplied with the amount of columns and rows respectively. For example, allowed window widths are always: (char_width * N) + base_width Currently, we always use a base_width of 2 * 2. This is to account for the padding of 2 pixels as specified in terminal.css. weltschmerz uses GtkScrolledWindow and overlay scrolling by default. With overlay_scrolling enabled, the scrollbar does not take up any extra space. The previous commit works around a problem with GtkScrolledWindow and sets PolicyType.ALWAYS when overlay scrolling is turned off. This means that we now also have to account for the size of that scrollbar. Since we cannot simply query the size of the scrollbar, we have to be a bit more creative. Use the full window width and subtract the width of the terminal at startup (we know it is always 80 columns) to get the amount of space taken up by "anything else". This includes VTE padding and the scrollbar size. Importantly, this needs only be done once and is completely agnostic to any further changes to the terminal or font size (which affects the cell width and height). We only assume that both the size of the scrollbar and the amount of padding is constant, which we feel to be a reasonable trade-off.
2021-06-19Always draw the scrollbar if overlay scrolling is offWolfgang Müller-2/+18
weltschmerz uses GtkScrolledWindow to provide a vertical scrollbar to the user. By default, this widget enables overlay scrolling. This means that the scrollbar is painted "inside" the terminal, as if overlaid. There's no configuration switch to turn this behaviour off, since we are convinced that overlay scrolling is the right thing to do for terminals. However, GTK allows users to turn off overlay scrolling in a global setting [1] or by using the 'GTK_OVERLAY_SCROLLING' environment variable. Some distributions turn overlay scrolling off by default. When overlay scrolling is disabled, GtkScrolledWindow falls back to rendering the scrollbar normally. Since our scrollbar policy is set to AUTOMATIC, it is only drawn on demand. This means that it is initially not be visible but can suddenly take up effective window space once it appears. When this happens, depending on what is going on in the terminal, one can be left with a terminal that is scrolling down infinitely as the reported column width flaps between two values: one accounting for the size of the scrollbar and the other one ignoring it. Each time the column width flaps, VTE sends SIGWINCH, possibly getting caught in an infinite loop of internal resizes. Since upstream declares GtkScrolledWindow incompatible with VTE [2] [3], we have not attempted further investigation on this issue, but may report an issue in the future. We definitely want to keep using GtkScrolledWindow even with this incompatibility - it is the most elegant and visually pleasing solution. The alternative would be to use a GtkBox and supply our own scrollbar. This scrollbar would either always be visible (even if there is nothing to scroll) or entirely hidden. An implementation of this may be found in the box-scroll branch. Note, however, that we do not guarantee that branch to be up to date with the latest developments. To work around this problem, detect when overlay scrolling is turned off and fall back to PolicyType.ALWAYS. This ensures that the scrollbar is always visible, mitigating the infinite resize loop. Crucially, compared to the alternative solution, this will still enable users to enjoy overlay scrolling if they (or their distribution) do not turn it off.

2021-06-19Always hide the horizontal scrollbarWolfgang Müller-1/+1
Even though PolicyType.AUTOMATIC should always keep it hidden, be explicit about our wish to show it under no circumstances.
2021-06-19Remove trailing comma from geometry initializerWolfgang Müller-1/+1
Commit c49fbfb (Set minimum width and height in window geometry, 2021-06-17) introduced a trailing comma to make subsequent changes to the initializer less of a hassle. However, Vala only accepts trailing commas starting with 0.52.3 [1]. It would be petty to require this version, especially since older versions of Vala can still compile weltschmerz without problems.

2021-06-18Set minimum width and height in window geometryWolfgang Müller-3/+8
weltschmerz currently does not indicate any minimum size for its window geometry. If the minimum size is not set, GtkWindow uses its requisition as the minimum size [1]. Make sure, instead, that we control this value and set it to one cell. [1] https://valadoc.org/gdk-3.0/Gdk.Geometry.html
2021-06-17Add setting for controlling cursor blinkingJuhani Krekelä-0/+1
Currently weltschmerz always uses the global GTK setting for cursor blink, which means that the cursor blink setting is stored separately from the rest of the configuration. Add a setting for overriding it in the config file, so that all the relevant settings can be adjusted in one standardized place. Reviewed-by: Wolfgang Müller <wolf@oriole.systems>
2021-04-29Declare all GtkChild widgets as unownedWolfgang Müller-14/+14
See [1] for background. This was motivated by a warning from valac-0.50. [1] https://gitlab.gnome.org/GNOME/vala/-/issues/1121
2020-04-13Move get_shell to utils.valaWynn Wolf Arbor-15/+1
There was no VTE-related functionality in this method, so we can find a better place for it now that a dedicated utility class exists.
2020-04-13Add Open directory featureWynn Wolf Arbor-1/+16
VTE can leverage the child program's support of OSC 7 to keep track of the current directory. This commit adds support for opening said directory in the default file manager, either by using a shortcut or by activating a new entry in the context menu.
2020-04-13Add Copy to HTML featureWynn Wolf Arbor-6/+10
This commit adds a "Copy to HTML" entry to the context menu. It is active when VTE registers an active selection. Lines copied like this will be put into the clipboard as formatted HTML, retaining nearly all styling information. For this, vte_copy now takes a boolean argument - whether or not to format the lines copied as HTML. As two menu items now access vte_copy directly, and there is no clean way of passing arguments to signal handlers through terminal.ui, signals for both menu items are now connected in the Vala code instead.
2020-04-13Add OSC 8 hyperlink supportWynn Wolf Arbor-9/+28
This commit adds support for the OSC 8 hyperlink escape sequence [1]. As this is not a mature feature and there seem to be outstanding security concerns [2], the setting that controls whether or not OSC 8 is interpreted is disabled by default. Just like gnome-terminal, weltschmerz will display a tooltip with the canonicalized URI when hovering over a hyperlink.

2020-02-04Improve configuration handlingWynn Wolf Arbor-60/+13
This commit improves and simplifies weltschmerz's configuration handling. Obtaining and parsing the KeyFile is split out into ConfigReader, which is fully agnostic of the specific configuration values. Config now contains all configuration values in the form of primitive types or class instances, and no longer delegates access to the KeyFile structure directly. This means that the configuration file is read once, and then kept in the Config instance. Indirectly this commit also fixes a bug where weltschmerz would segfault if one of the palette entries contained an invalid value.
