2014-09-14Display current mode in window statusbarMarc André Tanner2-11/+14
For now just display the modes which start with '-'. I want to keep the descriptive names of the other modes available for debugging purposes.
2014-09-14Fix save to absolute pathsMarc André Tanner1-9/+14
The save logic still needs changes to restore file permissions, ownership (if run as root) etc.
2014-09-14Add a dummy man page inorder to fix make installMarc André Tanner1-0/+16
2014-09-14Make byte based iterator API handle the whole range [0, size]Marc André Tanner2-6/+34
Before this commit the valid range was [0, size) which represents the file content. For the position at EOF (=size) a NUL byte is returned which is not actually part of the underlying file. This should fix various movements / editing operations at the end of the file. For example Ctrl+w at the end of the command prompt.

2014-09-13Introduce and use EPOS instead of (size_t)-1Marc André Tanner5-19/+21
2014-09-13Make window_selection_get to return the correct rangeMarc André Tanner1-1/+5
This makes the operator operate on the correct file range if executed from visual mode. The problem is that if the cursor is visible the selection seems larger than it actually is. The cell under the cursor is actually not part of the selection eventhough it is visually indistinguishable from it. The somewhat hacky way around this is to hide the cursor once selection is active and show it again once the selection is cleared. This will probably cause a headache if the cursor needs to be visible while a selection is active like for example in the command prompt.
2014-09-13Add a READMEMarc André Tanner1-0/+518
This is for now just a mail originally sent to the suckless mailing list.
2014-09-13Fix 'G' movement to end of fileMarc André Tanner1-1/+1
action.count is 1 by default. notice that this breaks 1G which should move to the first line / start of file.

H moves to the n-th window line from top M moves to the middle window line L moves to the n-th window line from bottom

2014-09-12Make sure that the state is consistent after an undo operationMarc André Tanner1-0/+2
When performing an undo operation, further changes should not be accounted to the then active action. Therefore take a snapshot which resets txt->current_action to NULL.
