[CustomMessages] section

[CustomMessages] section用来定义自定义的一些{cm:}常量.

一个定义和使用的例子。

[CustomMessages]
CreateDesktopIcon=Create a &desktop icon

[Tasks]
Name: desktopicon; Description: "{cm:CreateDesktopIcon}"

CustomMessages是支持带参数的，从1%到9% 。支持重排列参数（例如，2%移动到了1%前面），也支持重复的参数（例如，1% …1% 2% ）。在有参数的message中，用两个连续的“%”来嵌入一个“%”，“%n”会创建一个line break。

In cases where there are multiple [Languages] section entries, specifying a [CustomMessages] section entry in your script (as opposed to an .isl file) will by default override that message for all languages. To apply a [CustomMessages] section entry to only one language, prefix it with the language’s internal name followed by a period. For example:

nl.CreateDesktopIcon=Maak een snelkoppeling op het &bureaublad

Currently, the .isl files for all languages that come with Inno Setup have the following custom messages defined and translated for each language (shown here with their English values):

NameAndVersion=%1 version %2
AdditionalIcons=Additional icons:
CreateDesktopIcon=Create a &desktop icon
CreateQuickLaunchIcon=Create a &Quick Launch icon
ProgramOnTheWeb=%1 on the Web
UninstallProgram=Uninstall %1
LaunchProgram=Launch %1
AssocFileExtension=&Associate %1 with the %2 file extension
AssocingFileExtension=Associating %1 with the %2 file extension...
AutoStartProgramGroupDescription=Startup:
AutoStartProgram=Automatically start %1
AddonHostProgramNotFound=%1 could not be located in the folder you selected.%n%nDo you want to continue anyway?

You may use these predefined custom messages in your own script. An example which uses UninstallProgram:

[Icons]
Name: "{group}\{cm:UninstallProgram,My Program}"; Filename: "{uninstallexe}"

1 {cm:MessageName}

{cm:MessageName}
{cm:MessageName,Arguments}
Embeds a custom message value based on the active language.

MessageName specifies the name of custom message to read from. See the [CustomMessages] section documentation for more information.
Arguments optionally specifies a comma separated list of arguments to the message value.
If you wish to include a comma, vertical bar (“|”), or closing brace (“}”) inside the constant, you must escape it via “%-encoding.” Replace the character with a “%” character, followed by its two-digit hex code. A comma is “%2c”, a vertical bar is “%7c”, and a closing brace is “%7d”. If you want to include an actual “%” character, use “%25”.
Each argument in Arguments may include constants. Note that you do not need to escape the closing brace of a constant as described above; that is only necessary when the closing brace is used elsewhere.

Example:
{cm:LaunchProgram,Inno Setup}
