When repositories are packaged, certain keyword substitutions take place on text files.

Simple replacements

@file-revision@
Turns into the current revision of the file in integer form. e.g. 1234
Note: For Git, this will use the file hash.
@project-revision@
Turns into the highest revision of the entire project in integer form. e.g. 1234
Note: For Git, this will use the commit hash.
@file-hash@
Turns into the hash of the file in hex form. e.g. 106c634df4b3dd4691bf24e148a23e9af35165ea
Note: No replacement will occur for Subversion.
@project-hash@
Turns into the hash of the entire project in hex form. e.g. 106c634df4b3dd4691bf24e148a23e9af35165ea
Note: No replacement will occur for Subversion.
@file-abbreviated-hash@
Turns into the abbreviated hash of the file in hex form. e.g. 106c63 Note: No replacement will occur for Subversion.
@project-abbreviated-hash@
Turns into the abbreviated hash of the entire project in hex form. e.g. 106c63
Note: No replacement will occur for Subversion.
@file-author@
Turns into the last author of the file.
@project-author@
Turns into the last author of the entire project.
@file-date-iso@
Turns into the last changed date (by UTC) of the file in ISO 8601. e.g. 2008-05-01T12:34:56Z
@project-date-iso@
Turns into the last changed date (by UTC) of the entire project in ISO 8601. e.g. 2008-05-01T12:34:56Z
@file-date-integer@
Turns into the last changed date (by UTC) of the file in a readable integer fashion. e.g. 20080501123456
@project-date-integer@
Turns into the last changed date (by UTC) of the entire project in a readable integer fashion. e.g. 2008050123456
@file-timestamp@
Turns into the last changed date (by UTC) of the file in POSIX timestamp. e.g. 1209663296
@project-timestamp@
Turns into the last changed date (by UTC) of the entire project in POSIX timestamp. e.g. 1209663296
@project-version@
Turns into an approximate version of the project. The tag name if on a tag, otherwise it's up to the repo.
:SVN returns something like "r1234"
:Git returns something like "v0.1-873fc1"
:Mercurial returns something like "r1234".

Debug replacements

These occur based on filetype, as they tend to tie into the comment system for the file.

The insides aren't removed so that line numbers stay the same, they just cause them to be commented out.

Lua

--@debug@ and --@end-debug@
Turns into --[===[@debug and --@end-debug]===].
--[===[@non-debug@ and --@end-non-debug@]===].
Turns into --@non-debug@ and --@end-non-debug@.

XML

<!--@debug@--> and <!--@end-debug@-->
Turns into <!--@debug and @end-debug@-->.
<!--@non-debug@ and @end-non-debug@-->.
Turns into <!--@non-debug@--> and <!--@end-non-debug@-->.

TOC

#@debug@ and #@end-debug@
Turns into #@debug@ and #@end-debug@, as well as adding a # to the beginning of each line in-between.

Exclude from packaging

These occur based on filetype, as they tend to tie into the comment system for the file.

--@do-not-package@ and --@end-do-not-package@ (for Lua)
<!--@do-not-package@--> and <!--@end-do-not-package@--> (for XML)
#@do-not-package@ and #@end-do-not-package@ (for TOC)
Removes everything between the @do-not-package@ and @end-do-not-package@ tags including the 2 tags themselves. This may cause line numbers of subsequent lines to change. The typical usage is at the end of Lua files surrounding debugging functions and other code that end users should never see/execute.

Because of pre-commit hooks, you will still need to comment out the @do-not-package@ and @end-do-not-package@ tags for the relevant file types.

Alpha Replacements

These occur based on filetype, as they tend to tie into the comment system for the file.

The insides aren't removed so that line numbers stay the same, they just cause them to be commented out.

These occur from packages created not from tags, i.e. alpha packages.

This is useful to put extra debugging information that you want your alpha testers to have, but don't want to appear in release versions.

Lua

--@alpha@ and --@end-alpha@
Turns into --[===[@alpha and --@end-alpha]===].
--[===[@non-alpha@ and --@end-non-alpha@]===].
Turns into --@non-alpha@ and --@end-non-alpha@.

Example:

--@alpha@
assert(everythingIsOkay())
--@end-alpha@

This would make it so the assert takes place in dev mode and alpha zips, but doesn't bother for release and beta.

XML

<!--@alpha@--> and <!--@end-alpha@-->
Turns into <!--@alpha and @end-alpha@-->.
<!--@non-alpha@ and @end-non-alpha@-->.
Turns into <!--@non-alpha@--> and <!--@end-non-alpha@-->.

TOC

#@alpha@ and #@end-alpha@
Turns into #@alpha@ and #@end-alpha@, as well as adding a # to the beginning of each line in-between.

No-lib Replacements

These occur based on filetype, as they tend to tie into the comment system for the file.

The insides aren't removed so that line numbers stay the same, they just cause them to be commented out.

These only occur on packages marked as -nolib.

TOC

#@no-lib-strip@ and #@end-no-lib-strip@.
Turn into #@no-lib-strip@ and #@end-no-lib-strip@, as well as adding a # to the beginning of each line in-between.

XML

<!--@no-lib-strip@--> and <!--@end-no-lib-strip@-->.
Turn into <!--@no-lib-strip and @end-no-lib-strip@-->.
