[PATCH v4 0/3] vsh: Introduce new API for printing tables

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Created new API for priting tables, mainly to solve alignment problems.
Implemented these test to virsh list. In the future, API may be
everywhere in virsh and virt-admin.
Also wrote basic tests for the new API, and corrected tests in virshtest
which are influenced by implementation of the API in virsh list.

Changes in v4:
- fixed width calculation for zero-width, nonprintable and combined
character. (pulled some code from linux-util)
- added tests for cases mentioned above
- changed usage of vshControl variables. From now on PrintToStdout calls
PrintToString and then prints returned string to stdout

Changes in v3:
- changed encoding of 3/3 patch, otherwise it cannot be applied

Changes in v2:
- added tests
- fixed alignment for unicode character which span more spaces
- moved ncolumns check to vshTableRowAppend
- changed arguments for functions vshTablePrint, vshTablePrintToStdout,
    vshTablePrintToString
