[pacman-dev] [PATCH] Add line number to RET_ERR{,_VOID}
by Allan McRae 09 Mar '20

09 Mar '20

Following the example of the recently added GOTO_ERR, adding the line number in addition to the function name in our debug messages is potentially useful.

[pacman-dev] [PATCH] Add GOTO_ERR() macro to set error and then goto a label
by Anatol Pomozov 09 Mar '20

This is a macro similar to RET_ERR but useful in the case when we need to record an error and then jump to some cleanup section.

[pacman-dev] [PATCH v2] Hide cursor while pacman is running
by Anatol Pomozov 08 Mar '20

Use ASCII control codes to hide cursor at the pacman start and then show the cursor when pacman finishes. It helps to avoid annoying blinking when progress bars are re-drawn. Cursor is reenabled if pacman expects user's input.
