| == Systematic Approach ==
| | {{MovedToTrac|MessageStandardization}} |
| * Collect all possible error states from functions
| |
| * assign error codes for macros?
| |
| | |
| * G_option() parameters (like output->description = ("Path to resulting ASCII file");)
| |
| | |
| == Message standardization ==
| |
| | |
| === How should Errors/Warnings/Messages be formatted ===
| |
| * strings < >
| |
| * numbers [ ]
| |
| | |
| === Macros to be defined for C library ===
| |
| * MSG_RASTER_NOT_FOUND_IN_MAPSET - "Raster map <%s> not found in <%s>"
| |
| * MSG_CANNOT_OPEN_RASTER - "Failed opening raster map <%s>"
| |
| * MSG_CANNOT_OPEN_FILE - Cannot open file <%s>
| |
| | |
| Note: Problem with xgettext package. How to use macros to work with xgettext?
| |
| | |
| == Parameters and flags ==
| |
| | |
| Fix the parameters and flags. Make it a concept. See proposal in GRASS 5 [http://freegis.org/cgi-bin/viewcvs.cgi/grass/documents/parameter_proposal.txt?rev=HEAD&content-type=text/vnd.viewcvs-markup documents/parameter_proposal.txt]
| |
| | |
| == Verbosity levels ==
| |
| | |
| === Current abstract concept ===
| |
| | |
| {| | |
| |-
| |
| |verbose || 3 || MAX_LEVEL || print progress and all messages messages
| |
| |-
| |
| |standard || 2 || STD_LEVEL || print progress and selected messages
| |
| |-
| |
| |brief || 1 || || print only progress information
| |
| |-
| |
| |silent but not mute || 0 || MIN_LEVEL || print nothing (but ERR and WAR)
| |
| |-
| |
| |mute || 2>&1 > /dev/null
| |
| |-
| |
| |}
| |
| | |
| ;Proposal
| |
| | |
| * module output (should be "parsable") is not controlled by GRASS_VERBOSE [use fprintf (stdout, ...)]
| |
| * silent
| |
| ** only warnings and fatal errors are printed
| |
| * brief
| |
| ** all G_percent() and selected G_message() (especially connected to progress information, up to the programmer ??)
| |
| * standard
| |
| ** all G_percent() and selected G_message()
| |
| * verbose
| |
| ** all G_percent() + G_message()
| |
| | |
| ;Modification
| |
| | |
| * '''remove''' verbose level → standard == all G_percent () + G_messages()
| |
| * move some messages to G_debug()
| |
| * change level numbers to 1, 3, 5
| |
| * Add new G_msg(int level, "%format", ...); lib function. Existing G_message() could stay and would be the same as G_msg(LEVEL_STD,...).
| |
| | |
| ;Discussion
| |
| | |
| * HB: I'm quite happy to leave the current system as it is, but use GRASS_MESSAGE_FORMAT=silent to switch off G_percent(),G_clicker() output.
| |
| :Mixing a sliding verbosity scale plus a binary switch or >= rule for when G_percent() happens in the same variable is very messy IMO.
| |
| | |
| === Alternative Abstract concept ===
| |
| | |
| {|
| |
| |-
| |
| |standard || 3 || PERMSG_MODE || print progress and messages
| |
| |-
| |
| |standard || 2 || MESSAGE_MODE || print only messages
| |
| |-
| |
| |brief || 1 || PERCENT_MODE || print only progress information
| |
| |-
| |
| |silent but not mute || 0 || QUIET_MODE || print nothing (but ERR and WAR)
| |
