# wmllint -- check WML for conformance to the most recent dialect
#
# By Eric S. Raymond April 2007.
#
#                              PURPOSE
#
# wmllint is a tool for porting and debugging WML (Wesnoth Markup Language).
# It can do much of the work of upgrading old content to a new version of
# Battle for Wesnoth, automatically.
#
# While the script is at it, it checks for various incorrect and dodgy WML
# constructs, including:
#   * unbalanced tags
#   * strings that need a translation mark and should not have them
#   * strings that have a translation mark and should not
#   * translatable strings containing macro references
#   * filter references by id= not matched by an actual unit
#   * abilities or traits without matching special notes, or vice-versa
#   * consistency between recruit= and recruitment_pattern= instances
#   * unknown unit types in recruitment lists
#   * double space after punctuation in translatable strings.
#   * unknown races or movement types in units
#   * unknown base units
#   * misspellings in message and description strings
#
#                              BASIC PROCEDURE
#
# Takes any number of directories as arguments.  Each directory is converted.
# If no directories are specified, acts on the current directory.
#
# The recommended procedure is this:
# 1. Run it with --dryrun first to see what it will do.
# 2. If the messages look good, run without --dryrun; the old content
#    will be left in backup files with a -bak extension.
# 3. Eyeball the changes with the --diff option.
# 4. Use wmlscope, with a directory list including the Wesnoth mainline WML
#    as first argument, to check that you have no unresolved references.
# 5. Test the conversion.
# 6. Use either --clean to remove the -bak files or --revert to
#    undo the conversion.
#
# Compatibility with pre-1.4 versions has been removed; to port very old
# content, first run wmllint-1.4 to convert to "1.4", before running this
# one.
#
# Standalone terrain mask files *must* have a .mask extension on their name
# or they'll have an incorrect usage=map generated into them.
#
#                              MAGIC COMMENTS
#
# Note: You can shut wmllint up about custom terrains by having a comment
# on the same line that includes the string "wmllint: ignore" or
# "wmllint: noconvert". The same magic comments will also disable checking
# of translation marks, which may alternatively be toggled for line blocks
# with "wmllint: markcheck off" and "wmllint: markcheck on".
#
# You can also prevent description insertions with "wmllint: no-icon".
#
# You can force otherwise undeclared characters to be recognized with
# a magic comment containing the string "wmllint: recognize".
# The rest of the line is stripped and treated as the name of a character
# who should be recognized in descriptions.  This will be useful,
# for example, if your scenario follows a continue so there are
# characters present who were not explicitly recalled.  It may
# also be useful if you have wrapped unit-creation or recall markup in
# non-core macros and wmllint cannot recognize it.
#
# If you use custom macros to create (or recall) a named unit, you can tell
# wmllint which field contains the id with the string, "wmllint: whofield
# <macro> <number>".  After the macro's last use, *make sure* to remove it
# with "wmllint: whofield clear <macro>"; if "clear" is not followed by a
# macro name, all macros will be cleared from the list.  (If the <number>
# string was not a non-zero number, wmllint will also attempt to remove the
# specified macro.)
#
# For macros used in multiple scenarios to field characters, you can tell
# wmllint to recognize them with another magic comment:
#     wmllint: who <macro> is <character(s)>
# <Macro> should be the macro name; <character(s)> would be the ids of the
# recalled (or created) characters, comma-separated if there were more than
# one.  If more characters attach to a macro in later scenarios, they can be
# appended with additional "who" magic comments (though this requires scenarios
# to be numbered or otherwise sorted to work properly, as wmllint traverses
# files in alphabetical order).  If there is a character that drops out,
# preceding that person's entry with a double-minus will cause that character
# to be removed, e.g., "-- Garak".
#
# At the end of the campaign, *make sure* you use:
#     wmllint: unwho ALL
# This will clear the list of "who" magic comments and tell wmllint to stop
# checking for them in later files and directories.  If a specific macro is
# not used in subsequent scenarios, put "unwho <macro>" in its last scenario.
#
# Similarly, it is possible to explicitly declare a unit's usage class
# with a magic comment that looks like this:
#    wmllint: usage of <unit> is <class>
# Note that <unit> must be a string wrapped in ASCII doublequotes.  This
# declaration will be useful if you are declaring units with macros that
# include a substitutable formal in the unit name; there were examples in
# UtBS, but they have since been converted to use the [base_unit] tag.
#
# If a mismatch between a recruit list and recruitment pattern involves a
# usage type outside the five core types, the warning message will include a
# note that a non-standard usage class is involved.  If you are using custom
# usage classes and would like wmllint to be aware of them, you can insert
# the magic comment, "wmllint: usagetype <class>".  This comment will take a
# comma-separated list, and can also be pluralized to "usagetypes".
#
# You can disable stack-based malformation checks with a comment
# containing "wmllint: validate-off" and re-enable with "wmllint: validate-on".
#
# You can prevent filename conversions with a comment containing
# "wmllint: noconvert" on the same line as the filename.
#
# You can suppress complaints about files without an initial textdomain line
# by embedding the magic comment "# wmllint: no translatables" in the file.
# of course, it's a good idea to be sure this assertion is actually true.
#
# You can skip checks on unbalanced WML (e.g. in a macro definition) by
# bracketing it with "wmllint: unbalanced-on" and "wmllint: unbalanced-off".
# Note that this will also disable stack-based validation on the span
# of lines they enclose.
#
# You can suppress warnings about newlines in messages (and attempts to
# repair them) with "wmllint: display on", and re-enable them with
# "wmllint: display off".  The repair attempts (only) may also be
# suppressed with the --stringfreeze option.
#
# A special comment "# wmllint: notecheck off" will disable checking unit types
# for consistency between abilities/weapon specials and usage of special notes
# macros in their descriptions.
# The comment "# wmllint: notecheck on" will re-enable this check.
#
# A special comment "# wmllint: deathcheck off" will disable the check whether
# dying units speak in their death events.
# The comment "# wmllint: deathcheck on" will re-enable this check.
#
# A magic comment of the form "wmllint: general spellings word1
# word2..."  will declare the tokens word1, word2, etc. to be
# acceptable spellings for anywhere in the Wesnoth tree that the
# spellchecker should never flag.  If the keyword "general" is
# replaced by "local", the spelling exceptions apply only in the
# current file. If the keyword "general" is replaced by "directory",
# the spelling exceptions apply to all files below the parent
# directory.
#
# A comment containing "no spellcheck" disables spellchecking on the
# line where it occurs.
#
# A comment of the form
#
# #wmllint: match {ABILITY_FOO} with {SPECIAL_NOTES_IOO}
#
# will declare an ability macro and a special-notes macro to be tied
# together for reference-checking purposes.
#
# In 1.11.5 and 1.11.6 respectively, the special ellipses for leaders and units
# without a ZoC are automatically handled by the C++ engine. wmllint warns if such
# ellipses are found in your WML and asks to remove them; at the same time it
# notifies of custom ellipses that may need to be updated (updating means that
# -nozoc, -leader and -leader-nozoc variations of your ellipse need to be added).
# You can disable this sanity check for the current line with the comment
# "# wmllint: no ellipsecheck".
#
#                              DEVELOPER INFORMATION
#
# All conversion logic for lifting WML and maps from older versions of the
# markup to newer ones should live here.  This includes resource path changes
# and renames, also map format conversions.
#
# Note: Lift logic for pre-1.4 versions has been removed; if you need it,
# use wmllint-1.4 to lift before running this one.  I did this for a policy
# reason; I wanted to kill off the --oldversion switch.  It will *not*
# be restored; in future, changes to WML syntax *must* be forward
# compatible in such a way that tags from old versions can be
# unambiguously recognized (this will save everybody heartburn).  As a
# virtuous side effect, this featurectomy cuts wmllint's code
# complexity by over 50%, improves performance by about 33%, and
# banishes some annoying behaviors related to the 1.2 map-conversion
# code.

Usage: wmllint [options] [dir]
    Convert Battle of Wesnoth WML from older versions to newer ones.
    Also validates WML to check for errors.

    Takes any number of directories as arguments.  Each directory is converted.
    If no directories are specified, acts on the current directory.

Mode options:
    Changes wmllint from default conversion mode.  Only one mode can be chosen.
    -h, --help                 Emit this help message and quit.
    -d, --dryrun               List changes (-v) but don't perform them.
    -c, --clean                Clean up -bak files.
    -D, --diff                 Display diffs between converted and unconverted
                               files.
    -r, --revert               Revert the conversion from the -bak files.

Other options:
    -v, --verbose              -v        lists changes.
                               -v -v     names each file before it's processed.
                               -v -v -v  shows verbose parse details.
    -m, --missing              Don't warn about tags without side= keys now
                               applying to all sides.
    -s, --stripcr              Convert DOS-style CR/LF to Unix-style LF.
    -K, --known                Suppress check for unknown unit types, recruits,
                               races, scenarios, etc.
    -S, --nospellcheck         Suppress spellchecking
    -Z, --stringfreeze         Suppress repair attempts of newlines in messages

positive warnings with magic comments, read the introduction in the wmllint
file itself.  See also: http://wiki.wesnoth.org/Maintenance_tools.

        Explanation:

Windows' use of the backslash as a directory separator is clashing with the use of the backslash as an escape. As an escape, the backslash tells your system that you want a normally special character to be its literal self (or sometimes, that you want a normally ordinary character to have a special meaning). Your system interprets '\\"' as an escape for a literal quote character. Two quotes together are also interpreted as a literal quote.

'"Campaign\\"' is interpreted as 'Campaign"' instead of 'Campaign\\'.
'"My Folder\\"Campaign' is interpreted as 'My Folder"Campaign' (not 'My Folder\Campaign').
'"My Folder\Campaign\\" "My Folder\Another_Campaign"' is interpreted as 'My Folder\Campaign" My' and 'Folder\Another_Campaign'.

In your case, your system interprets your arguments as:

    %s

        Solutions:

(1) If your problem is adjoining quotes, delete (or move) one of them
(  "folder\Campaign"" -> "folder\Campaign"  )

(2) If you are using a final backslash at the end of a directory address, it is not necessary
(  "folder\Campaign\\" -> "folder\Campaign" -- but NOT "folder\Campaign\\"file.cfg -> "folder\Campaign"file.cfg  )

(3) If you add a second backslash, your system will then escape the backslash instead of the quote
(  "folder\Campaign\\" -> "folder\Campaign\\\\"  )

(4) Frontslashes will also be recognized as directory separators
(  "folder\Campaign\\" -> "folder/Campaign"  )

(5) If there are no spaces in your address, it is not necessary to use quotes
(  "folder\Campaign\\" -> folder\Campaign -- but NOT "My Folder\Campaign\\" -> My Folder\Campaign  )

(6) You can move the affected quote
(  M"y Folder\\"Campaign -> M"y Fold"er\Campaign -- but NOT Fil"es and Folders\My Folder\\"Campaign -> Fil"es and Folders\M"y Folder\Campaign  )

        Reminder:

(a) Hit the up arrow key. The up and down arrows move through your command history; one press of the up arrow will take you to your last command.
(b) Edit your command. Use any of the solutions described above.
(c) Press Enter
