Remove Voice Call Button from Telegram Desktop 1.6.3 (and above) on Arch Linux

how_to_apply.md

The steps below are outdated, but the next section could still be helpful.

Using patch file

1. Get familar with AES.

2. Run asp checkout telegram-desktop

3. cd to a directory with PKGBUILD in it

4. Place no_call_btn.patch in the current directory

5. Run the script

   old_hash=$(sha512sum tdesktop.patch | cut -f1 -d ' ')
   cat no_call_btn.patch >> tdesktop.patch
   new_hash=$(sha512sum tdesktop.patch | cut -f1 -d ' ')
   sed -i "s/$old_hash/$new_hash/" PKGBUILD

6. Execute makepkg -si and wait for about an hour. You can speed up the build process by passing -j4 parameter in make and cmake arguments list or by configuring your /etc/makepkg.conf (see MAKEFLAGS option).

7. If you are satisfied with the result, remove leftovers using makepkg -e --clean.

In order to preserve custom build of the client, add telegram-desktop to the section IgnorePkg in /etc/pacman.conf.

Manual editing

To keep Telegram Desktop up to date, one need to perform steps like the following:

1. cd to the ABS directory tree and execute asp update.
2. cd to a telegram-desktop directory with PKGBUILD in it.
3. Run git clean -fd . to remove all unstaged changes and execute git pull.
4. cd to trunk, download all the prerequisites, and remove all files related to the previouse build with makepkg -Co.
5. Edit manually $srcdir/src/tdesktop/Telegram/SourceFiles/history/view/history_view_top_bar_widget.cpp. ($srcdir == printf -- '%s/telegram-desktop/\n' $(fgrep BUILDDIR /etc/makepkg.conf | cut -d= -f2)).
6. Build the package from modified sources with makepkg -e.
7. If the build process complited without errors, install it: makepkg -i.
8. If you are satisfied with the result, remove leftovers using rm -rf $srchdir.
