After building, go into the "bin" folder and run this command to analyze the sample file:
i18n-check ../samples -o results.txt
This will produce a "results.txt" file in the "bin" folder with output like this:
| File | Line | Column | Value | Explanation | WarningID |
|---|---|---|---|---|---|
| ../samples/subset.cpp | 281 | 38 | "GreaterThanOrEqualTo" | String available for translation that probably should not be in function call: _ | [suspectL10NString] |
| ../samples/subset.cpp | 17 | 39 | "Invalid dataset passed to column filter." | Localizable string being used within non-user facing function call: wxASSERT_MSG | [suspectL10NUsage] |
| ../samples/subset.cpp | 93 | 52 | "'%s': string value not found for '%s' column filter." | String not available for translation in function call: std::runtime_error | [notL10NAvailable] |
| ../samples/subset.cpp | 131 | 38 | wxT | Deprecated text macro that can be removed. (Add 'L' in front of string to make it double-byte.) | [deprecatedMacro] |
| ../samples/subset.cpp | File contains extended ASCII characters, but is not encoding as UTF-8. | [nonUTF8File] | |||
| ../samples/subset.cpp | 56 | 33 | "'%s'— column not found for filtering." | String contains extended ASCII characters that should be encoded. | [unencodedExtASCII] |
The suspectL10NString warning is because there is a string "GreaterThanOrEqualTo" that is inside of a _()
macro, making it available for translation. This does not appear to be something appropriate for
translation, hence the warning.
The suspectL10NUsage warning is because the string "Invalid dataset passed to column filter." is being used
in a call to wxASSERT_MSG(), which is a debug assert function. Asserts normally should not appear
in production releases and shouldn't be seen by end users; therefore, they should not be translated.
The notL10NAvailable warning is indicating that the string "'%s': string value not found for '%s' column filter." is
not wrapped in a _() macro and not available for localization.
The deprecatedMacro warning is indicating that the text-wrapping macro wxT() should be removed.
The nonUTF8File warning is indicating that the file contains extended ASCII characters, but
is not encoded as UTF-8. It is generally recommended to encode files as UTF-8, making them portable between compilers and other tools.
The unencodedExtASCII warning is indicating that the string "'%s'— column not found for filtering." contains a hard-coded
extended ASCII character. It is recommended that these characters be encoded in hexadecimal format to avoid
character-encoding issues between compilers.
To look only for suspect strings that are exposed for translation and show the results in the console window:
i18n-check ../samples --enable=suspectL10NString,suspectL10NUsage
To look for all issues except for deprecated macros:
i18n-check ../samples --disable=deprecatedMacros
By default, i18n-check will assume that messages inside of various exceptions should be translatable.
If these messages are not exposed for localization, then a warning will be issued.
To consider exception messages as internal (and suppress warnings about their messages not being localizable) do the following:
i18n-check ../samples --exceptions-l10n-required=false
Similarity, i18n-check will also consider messages inside of various logging functions to be allowable
for translation. A difference is that it will not warn if a message is not exposed for translation. This is because
log messages can serve a dual role of user-facing messages and internal messages meant for developers.
To consider all log messages to never be appropriate for translation, do the following:
i18n-check ../samples --log-l10n-allowed=false
To display any code-formatting issues, enable them explicitly:
i18n-check ../samples --enable=allI18N,trailingSpaces,tabs,wideLine
or
i18n-check ../samples --enable=allI18N,allCodeFormatting
This will emit the following warnings:
| File | Line | Column | Value | Explanation | WarningID |
|---|---|---|---|---|---|
| ../samples/subset.cpp | 18 | 1 | "" | Tab detected in file; prefer using spaces. | [tabs] |
| ../samples/subset.cpp | 30 | 61 | "m_comparisonType = subsetCriterion.m_comparisonType;" | Trailing space(s) detected at end of line. | [trailingSpaces] |
| ../samples/subset.cpp | 31 | 12 | "" | Trailing space(s) detected at end of line. | [trailingSpaces] |
| ../samples/subset.cpp | 57 | 69 | "subsetCriterion.m_columnName).ToUTF8());" | Trailing space(s) detected at end of line. | [trailingSpaces] |
| ../samples/subset.cpp | 80 | 123 | " wxString::Format(_(L" )," | Line is 123 characters long. | [wideLine] |
