    Update macOS build instructions


    I tried the build instructions in the wiki but it seems Zeal moved to using cmake instead of qmake/make since those instructions were written.

    Do you have any updated hints on building Zeal on a Mac?

  • Error Message on start and crash on exit

    Error Message on start and crash on exit

    Hi, I am using the latest build (commit a4fac24a5dd9cb3df12794cd5485fb5daedf23f6 from 15/9/2016). I am on Ubuntu 16.04. Zeal crashes on exit with the error below. The issue wasn't with the previous build dated several months before. It seams that it causes also an error on start: "Another application instance can be still running, or has crashed. Make sure to start Zeal only once." pressing Retry helps but the error is for each start of the application.

    The error on exit:

    *** Error in `./zeal': free(): invalid next size (normal): 0x0000000002360c80 ***

  • Error in Docsets Browser (Windows)

    Error in Docsets Browser (Windows)

    Using Zeal 0.6.1 on Windows 10, with the C:\Users\bmix\AppData\Local\Zeal folder symlinked to a folder on another (local) volume, after opening the Tools -> Docsets... menu, I get the following two errors:.


    This happens each time. It happens while there is some progress bar on the bottom of the dialog, but it's too quick to see, what it is doing. I also don't understand, why it would want to remove them. I checked the folder's permissions, I checked the JSON configs and tried to find any differences to the other, working docsets, but did not find anything. This also happens after reboot. Thank you.

  • zeal desperately needs some love (and new UI features)

    zeal desperately needs some love (and new UI features)

    this app is awesome (i have no clue why documentation browsers aren't more of a thing). it saves me so much time. i use multiple editors -- VS Code and Emacs -- and i'm working from fairly recent Linux installations, so autocompletion, doc access and navigate to definition only occasionally work and i can't count on them being available. my current development environment is a work in progress.

    however Zeal desperately needs some new UI and other features; see below. I would consider contributing to this project, but there's a backlog on pullreqs and I think more collaboration is needed with Dash developers (why is Dash proprietary?! arggg!)

    • hide docsets and temporarily delist from search
    • favorites/bookmarks
    • integration of swagger/openAPI documentation
    • discovery for documentation repositories (these are all HTML with no javascript, right?)
    • documentation on generating docsets
    • documentation on converting from other docsets (e.g. man pages, doxygen, etc)
    • declarative configuration (and/or the ability to open XDG config files from the app)
    • portable configuration (easy to import from a new install)
    • a few more configurations (e.g. hotkeys)
    • support multiple versions of documentation
    • diff the HTML for Dash docsets or intelligently diff the API changes ... which can be done via the dash repo, i guess
    • better search
    • perhaps some social features (like medium comments or a feature to help indicate regions of docsets which need user contributions)
    • save documentation session (for window(s) or a tabset)
    • multiple windows

    it basically needs to be a thin browser that can be addressed/handled as an application by the OS (so i can wire up hotkeys and easily toggle to the docs for reference). for me, the main value here is that all my docs are in one place (& indexed/searchable).

    and what the hell is Algolia documentation search, why don't they have GUI apps and why the hell are they proprietary.

    sidenote on UI/UX design philosophy

    • when UI/UX features are not non-deterministically available -- like inconsistent docs/autocompletion availability in UX or pausing to visually ingest the mostly random arrangement of apps -- this implies conditioning to muscle memory will not occur and implies that processes which involve these apps/features/hotkeys require thread-blocking thought that disrupt your ability to focus on the task at hand...
    • by non-determinism, i mean that one can't deterministically count on pressing a button and getting what i want which means i can't make guarantees about whether i will quickly find information without looking for it. Zeal simplifies this. determinism is important for documentation systems, code editors and OS app management because it implies one action always gets one result and thus: you don't have to slow down and think about it.
    • the notion that the browser is a one-tool-fits-all-tasks is a plague on productivity for all kinds of users -- esp. without features like search for tabs, webapps that can be treated as apps by the OS. an app like zeal is like my documentation-place and i don't have to go through Google or spend nearly any time finding what I want. Trying to program should not feel like the Truth and Advertising episode of southpark.

    Persist the zoom level for the document browser

    The default font size is a little bit small for me, so I need to zoom in. This works well, but the zoom level is lost on the next launch, so I have to zoom it again. It would be great if the level is saved and gets automatically applied upon next launch.

  • Unable to register higher-numbered function keys as hide/show key

    Unable to register higher-numbered function keys as hide/show key

    As pretty much every convenient shortcut on my desktop is taken up by either my editor (hi, Emacs) or my window manager, I customized my keyboard to instead send high-numbered function keys (F18/XF86Launch9) instead. Unfortunately, while zeal allows setting the shortcut (it calls the key "Launch (B)"), it does not recognize the key as a global shortcut.

    This is what it writes to the console:

    QxtGlobalShortcut failed to register: Launch (B)
    QxtGlobalShortcut failed to unregister: Launch (B)

    Pressing the key apparently sends the event directly to the application that's focused, without interception by Zeal either. Is that a Qt issue?

    Feature request: disable/enable docsets

    Would be great to have an option to disable some of the doctests to exclude from search (instead of typing something like "python3:" before the request, which is kinda slow, even with Tab's autocomplete). Like a checkbox on the main screen or in docsets menu.

    Use case: having python3, django and flask docsets, but searching only in python3 by default (other docsets disabled). Right now I need to uninstall all other packages or use "python3:" each time to achieve that.

  • v0.1.0(Apr 15, 2015)

    A lot of changes have been made since the last release, so this change log cannot be considered complete, but merely an attempt to list most noticeable updates.

    This is the first release that follows a new versioning scheme based on Semantic Versioning. Please note, that now Zeal is considered in permanent beta status until a major version 1.0.0 is released. We will try to maintain minimal backward compatibility, but there are a lot of problems in the current code base, as well as ideas on how to make Zeal better. Our workflow is following:

    • bug fixes go into patch releases (e.g. 0.1.1 for 0.1.0);
    • new features go into minor releases (0.2.0, 0.3.0).

    Another important change is that the new Zeal relies on its own server for obtaining docset list and update information. For docset update to work properly you need to download all docsets again. From now docset icons are not embedded in Zeal, but come from the server as well. That means old docsets would lack icons until docsets are redownloaded.

    New features:

    • Follow a new versioning scheme. (#203)
    • Added support for Dash protocols dash: and dash-plugin: on Linux and Windows. (#247)
    • Revamped settings dialogue with more intuitive options.
    • Added a build option for portable mode (qmake CONFIG+=portable). In this case settings are stored in zeal.ini next to the Zeal executable, and docset storage path defaults to docsets subdirectory. Changing docset storage path via the settings dialogue has only temporary effect, and it is not saved on application exit. It is still possible to set a permanent custom path by manually editing zeal.ini.
    • Zeal now relies on its own server for obtaining docset list, rather than parsing Dash website.
    • Now the docset list is cached for 24 hours, but can be manually reloaded. (#287)
    • Implemented version check function (Help -> Check for Update...). (#282)
    • Improved display of docset download/unpack progress. (#252)
    • Now the main window of the running Zeal instance is brought up on attempt to start the app again. (#187)
    • Provided MSI installer for Windows users. (#279)
    • Removed Qt 4 support. Qt 5.2.0 or later is required.
    • --query CLI parameter is deprecated. Search query should be passed directly as an argument.

    Fixed issues:

    • Fixed missing index pages for some of the official Dash docsets. (#283)
    • Improved docset icon discovery. (#251, #264)
    • Fixed wrong version number in the about dialogue. (#246)
    • Fixed tons of other unmentioned bugs.

    Known problems:

    • Manually added Dash feeds lack auto-update feature. (#289)
    • Index search performance problems. Will be addressed in the new threaded full text search implementation. (#265, #280, #288)
    • There is an issue in Qt WebKit JavaScript engine that leads to significant slowdown and UI freezes on Windows 8 (mostly noticeable in Android and .NET docsets). (#265).
