* Fix glyph offsets in cellJoe Wilm2017-05-06
| | | | | | We previously had a hard-coded value for aligning glyphs within cells. The font descent is now used, and the offset should be correct by default.
* Fix bug with tab renderingJoe Wilm2017-05-01
| | | | | | | Closes #494. Resolves #529. Resolves #512. Resolves #493.

* Fix issue with back_color_eraseJoe Wilm2017-04-19
| | | | back_color_erase should not set flags like bold, underline, etc.
* Pass scrolling region tests in vttest 2Joe Wilm2017-04-19
|
* Partially add DECCOLM supportJoe Wilm2017-04-19
| | | | | | | | It's not possible with DECCOLM to temporarily set 80 or 132 column mode since the function is a toggle between the two. Instead, only the additional affects are run in order to get closer to passing vttest. vttest will never be perfect due to the column mode issue.

* Fix issue with htop rendering incorrectlyJoe Wilm2017-04-03
| | | | | | | Since we're emulating xterm, we need to support back_color_erase. If this is found to cause any issues, please open a ticket on GitHub. Resolves #85.
* Handle CSI command J3 (Clear saved lines)Aaron Hill2017-03-04
| | | | | | | | | | | | | | | | Xterm supports an extension to the CSI command `Erase in Display (ED)`, under the command number 3. This command is used to clear the scrollback buffer - e.g. anything not visible on the screen. Since scrollback is not part of alacritty, the handler for this command currently does nothing. If at some point scrollback is implemented, the corresponding `match` arm can be modified to properly handle this. For an example of a program which uses this command, run the `clear` command (using ncurses 6.0). In a supported terminal such as `gnome-terminal`, this will clear anything off of the screen from the scrollback buffer. Before this change, `alacritty` would generate an `Unhandled CSI` message.

* Update cell to cursor template when adding a tab.Anders Rasmussen2017-02-27

* Change cursor colors config to use text and cursorJoe Wilm2017-02-25
| | | | | | | | | | | | | This changes the cursor color config to use the `text` and `cursor` properties instead of the current `foreground` and `background` properties. The latter names stop making sense when dealing with cursors like a vertical bar or underscore. In the new system, the block, underscore, or vertical bar would always take the color of `cursor`, and the text would take the color of `text` when using a block, or keep its normal color when using the underscore or vertical bar. A warning is now emitted on startup when the old form of cursor color config is used. This will be a hard error in the future.
* Lazily reset `start_time` in VisualBell's `completed` methodMark Andrus Roberts2017-02-22
| | | | | | | | | | | | Fixes #416. Here's what I think is happening: at short `duration`s, the VisualBell's [`completed` check](https://github.com/jwilm/alacritty/blob/3ce6e1e4b2924b0d432cbb3e62b4bbef88dd38ff/src/term/mod.rs#L377) is returning `true` before we've actually had a chance to draw the "normal" background color. I thought about driving this condition off of whether or not `intensity` returns 0.0, but we may still miss a draw, I think. Perhaps the best way to tackle this is to let `completed` lazily reset the VisualBell's `start_time` (something @jwilm asked about when this feature originally landed), and to only return `true` when the VisualBell's `start_time` is `None`. This should effectively delay the final draw until after the VisualBell completes.

* Handle OSC for setting indexed color valuesJoe Wilm2017-02-11
| | | | Resolves #26.
* Move color list to Term structJoe Wilm2017-02-11
| | | | | | | | The color list needs to be updated by the parser, and this isn't possible if it's on the config. This change makes sense semantically as well since it's really part of the terminal state. This is in preparation for OSC color parsing.

* Add visual bell supportMark Andrus Roberts2017-02-07
| | | | | | | | | | | | | | | | This commit adds support for a visual bell. Although the Handler in src/ansi.rs warns "Hopefully this is never implemented", I wanted to give it a try. A new config option is added, `visual_bell`, which sets the `duration` and `animation` function of the visual bell. The default `duration` is 150 ms, and the default `animation` is `EaseOutExpo`. To disable the visual bell, set its duration to 0. The visual bell is modeled by VisualBell in src/term/mod.rs. It has a method to ring the bell, `ring`, and another method, `intensity`. Both return the "intensity" of the bell, which ramps down from 1.0 to 0.0 at a rate set by `duration` and `animation`. Whether or not the Processor waits for events is now configurable in order to allow for smooth drawing of the visual bell.

* Fix bug with restore cursorJoe Wilm2017-02-03
| | | | | | The saved cursor position could previously end up outside of the grid if the terminal was resized to be smaller and then calling a restore. Restore now ensures the cursor line and column are within grid bounds.

* Fix bug introduced with save/restore patchJoe Wilm2017-02-02

* Implement save/restore cursor positionJoe Wilm2017-02-02
| | | | | | | | | | | | This passes the vttest for save and restore cursor position. The implementation was done according to: http://www.vt100.net/docs/vt510-rm/DECSC.html As of yet, there are a few things not supported by the terminal which should otherwise be saved/restored. vte was updated for a fix with CSI param parsing

* ansi: Designate and invoke graphic character setsRichard Palethorpe2017-01-21
| | | | | | Implement the designation of graphic character sets G0-G3 to ASCII or the Special character and line drawing glyphs. As well as the invokation/selection of the character sets (shift in, shift out and lock shifting).
* Proposal for line wrap - ^[[7h and ^[[7l (private)Michael Brumlow2017-01-11
| | | | | | | | | | | | | | | | | | These changes provide support for disabling auto line wrap which is currently default to on. 'tput rman' will now disable auto line wrap and alacritty will now not automatically wrap lines. 'tput sman' will now (re)enable auto line wrap and alacritty will now automatically wrap lines once it reaches the end of the line. My testing showed this to work the same as gnome-terminal. I should note that simply having ^[[7h or ^[[7l in a recording does not enable and disable line wrapping. This is the same behavior as gnome-terminal and xterm. Those cape codes come through as private which are not handled yet. I behave this is the correct behavior.

* Fixing panic on cat /dev/urandomMichael Brumlow2017-01-10
| | | | | | | | | | | | | | | | - Checks to make sure lines count coming from the pty are within a proper range before doing scrolling. - Sanitizes scroll region when being set. - Changes panic for unimplemented screen clear to a print statement. The first two changes ensure scrolling won't crash us. By sanitizing the region on set we don't have to complicate the scroll code with limits, mins, or maxes to ensure the scroll operation is within the range. Checking if the lines is greater than the total region allows us to simply clear the region and avoid subtracting large numbers from small ones.

| * Implementing line wrapping.Michael Brumlow2017-01-07
| | | | | | | | | | This implementation of line wrapping ensures self.cursor.col is never out of bounds, thus not requiring checking.
| * Better bounds checking.Michael Brumlow2017-01-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Remove the use of limit. - Reduce the number of comparisons. When using numbers provided by the PTY for subtractions there is a extra step of ensuring that we won't trigger failure on testing when trying to subtract form zero. ** NOTE ** This commit fails fails the tmux_git_log test. I am submitting a PR to talk about the test. I think the test was generated before a few things were fixed the final test gird still has cells that should have been scrolled off the screen. Also, comparing output from gnome-terminal there is no difference. So this PR is here to discuss and gather information on balding test and discussing the possibility that this test may be flawed. ** NOTE **
* | Fixing resize crashes.Michael Brumlow2017-01-07
|/ | | | | | | | | Most of the crashes on resize were due to columns and lines being set to zero. This causes all sorts of other checks within the code to ensure these values are greater than zero before running calculations. To avoid this we just need to ensure that lines and columns are some non zero value. This is seems to be what gnome terminal does. I have selected 2 lines and two columns for min terminal size for now.
