The documentation entry identifies the specific file you want to work with inside a documentation manual. The help functionality recognizes documentation entries in the following formats: Path style This format uses paths to represent the documentation entries you want to work with. This format assumes you are using the first path component as chapter and the rest of the path as section identifier both inside tcar-fs documentation manual as parent documentation structure. The field related to the part sectioning structure in the documentation entry (the second field) is assumed empty, as well. For example, if you want to document the directory trunk/Scripts/Bash/Functions/Help, then you can do it with the following command: centos-art help --edit trunk/Scripts/Bash/Functions/Help Colon style This format uses colons to represent the documentation entries you want to work with. In this format, the whole documentation entry is divided in fields using colon as separator character. Documentation entries written this way use each field to specify manual, part, chapter and section identifiers (in this order). The section identifier can use a path style or hyphen style to separate components. For example, if you want to document the directory trunk/Scripts/Bash/Functions/Help, then you can do it with any of the following commands: centos-art help --edit tcar-fs::trunk:Scripts/Bash/Functions/Help centos-art help --edit tcar-fs::trunk:scripts-bash-functions-help The documentation manual name specified in the first field of a colon style documentation entry, must match the name the name of the directory where the documentation manual is stored in. By default documentation manuals are written in trunk/Documentation/Models/Texinfo or trunk/Documentation/Models/Docbook directories, based on whether they are written in Texinfo or Docbook documentation format. The match relation between the manual name you provide in the documentation entry and the related directory name inside &TCAR; is case insensitive. The same is true for all other documentation entry fields. From these documentation entry formats, the colon style provides more flexibility than path style does. You can use documentation entries written in colon style to create and maintain different documentation manuals, including the tcar-fs documentation manual. This is something you cannot do with documentation entries written in path style because they confine all documentation actions to tcar-fs documentation manual. The centos-art help command accepts common options described in and the following specific options: --answer-yes Assume yes to all confirmation requests. --sync-changes Synchronizes available changes between the working copy and the central repository. --format="KEYWORD" Specifies the format of documentation entry source file. This information is used as reference to build the absolute path of documentation entry, so you always have to provide it in order to reach the documentation entry you want to work with. Possible values for this option are shown in . Keyword Description Supported texinfo Yes docbook No latex No linuxdoc ... No --search="KEYWORD" Looks for documentation entries that match the KEYWORD specified as value and display them one by one in the order they were found. The way each documentation entry is presented to you depends on the documentation format the related documentation manual was written on. --edit Edit the documentation entry provided as argument. The edition itself takes place through your default text editor (e.g., the one you specified in the EDITOR environment variable) one file at a time (i.e., the queue of files to edit is not loaded in the text editor.). When parent components inside documentation entries doesn't exist (e.g., you try to create a section for a documentation manual that doesn't exist), the help functionality will create all documentation parent structures considering the documentation format constraints and the following document structure hierarchy order: documentation manual first, parts second, chapters third and sections lastly. --read Read the documentation entry provided as argument. This option is used internally by centos-art.sh script to refer documentation based on errors, so you can know more about them and the causes that could have provoked them. --update-output Update output files rexporting them from the specified backend source files. --update-structure Update document structure (e.g., cross references, menus, nodes, etc.). This option should be used whenever a document structure changes (e.g., when documentation entries are added, copied, renamed, deleted, etc.). This option grantees the document integrity and should be run before the --update-output option. --copy Duplicate documentation entries inside the working copy using version control. When you duplicate documentation entries through this option, you should pass only two documentation entries in the command line. The first one is considered the source location and should point to a file under version control inside the working copy. The second one is considered the target location and should point either to the same structural level the source points to or a direct parent level based on source location, as described below. "manual:part:chapter:section-1" "manual:part:chapter:section-2" Duplicates section-1 as section-2 inside the same chapter, part and manual. "manual:part:chapter-1:" "manual:part:chapter-2:" Duplicates chapter-1 as chapter-2 inside the same part and manual. "manual:part-1::" "manual:part-2::" Duplicates part-1 as part-2 inside the same manual. "manual-1:::" "manual-2:::" Duplicates manual-1 as manual-2 inside trunk/Documentation/Models/${FLAG_FORMAT}/ directory, where ${FLAG_FORMAT} is the name of the format passed as option with the first letter in uppercase and the rest in lowercase. When you copy documentation entries through this option, all structuring sections inside the one copied will be also copied. For example, if you copy a documentation manual that is made of parts, chapters and sections, the duplicated manual will contain all those parts, chapters and sections, as well. The same is true for lower sectioning structures. Thus, you can be more specific in the documentation entry by reducing the amount of content to duplicate. When you copy documentation entries through this option, you do it using documentation entries in the same structural level only. This option doesn't support copying documentation entries from differnet structural levels. For example, you cannot copy one section to a chapter different from that the source section belongs to. The same applies to chapters, and parts. --delete Delete documentation entries. It is possible to delete more than one documentation entry by specifying several documentation entries in the command line. --rename Rename documentation entries inside the working copy. When documentation entries are renamed, it is required to pass only two non-option parameters to the command-line. The first non-option parameter is considered the source location and the second one the target location. Both source location and target location must point to a directory under the working copy. When documentation entries are removed (e.g., through --delete or --rename options), the help functionality takes care of updating nodes, menus and cross refentrys related to documentation entries in order to keep the manual structure in a consistent state. This section describes, using examples, the procedure you should follow to manage documentation manuals through help functionality inside &TCAR;. To better understand the procedure to follow, it describes a hypothetical documentation scenario and the related commands and outputs you may go through in order to complete specific documentation tasks successfully. To create new documentation manuals inside &TCAR; you need to provide the --edit option and a documentation entry in the form manual::: to the help functionality. For example, consider a scenario where you need to create a documentation manual in texinfo format to describe different maintenance tasks you need to realized in order to keep your pets happy. We'll name such manual My Zoo. It will use chapters to organize each different kind of pets you have. Inside chapters, sections will have the pet's name as their own name to describe each pet's requirements, schedules, and so on. To create such documentation manual, run the following command: centos-art help --edit --format="texinfo" "myzoo:::" In case such documentation manual doesn't exist in the trunk/Docuementation/Models/Texinfo/ directory, this command will produce the following output: The following documentation manual doesn't exist: --> trunk/Documentation/Models/Texinfo/MyZoo/en_US/myzoo.texinfo Do you want to create it now? [yes/no]: yes Enter manual's title: My Zoo Enter manual's subtitle: Maintenance reference Enter manual's abstract: This manual relates pets' maintenance tasks. Creating trunk/Documentation/Models/Texinfo/MyZoo Creating trunk/Documentation/Models/Texinfo/MyZoo/en_US Creating trunk/Documentation/Models/Texinfo/MyZoo/en_US/myzoo.conf Creating trunk/Documentation/Models/Texinfo/MyZoo/en_US/myzoo-index.texinfo Creating trunk/Documentation/Models/Texinfo/MyZoo/en_US/myzoo-menu.texinfo Creating trunk/Documentation/Models/Texinfo/MyZoo/en_US/myzoo-nodes.texinfo Creating trunk/Documentation/Models/Texinfo/MyZoo/en_US/myzoo.texinfo Creating trunk/Documentation/Models/Texinfo/MyZoo/en_US/Licenses/chapter-menu.texinfo Creating trunk/Documentation/Models/Texinfo/MyZoo/en_US/Licenses/chapter-nodes.texinfo Creating trunk/Documentation/Models/Texinfo/MyZoo/en_US/Licenses/chapter.texinfo Updating trunk/Documentation/Models/Texinfo/MyZoo/en_US/myzoo.texinfo Updating trunk/Documentation/Manuals/Texinfo/MyZoo/en_US/myzoo.info.bz2 Updating trunk/Documentation/Manuals/Texinfo/MyZoo/en_US/myzoo.xhtml.tar.bz2 Updating trunk/Documentation/Manuals/Texinfo/MyZoo/en_US/myzoo.xml Updating trunk/Documentation/Manuals/Texinfo/MyZoo/en_US/myzoo.docbook Updating trunk/Documentation/Manuals/Texinfo/MyZoo/en_US/myzoo.pdf Updating trunk/Documentation/Manuals/Texinfo/MyZoo/en_US/myzoo.txt.bz2 Once the documentation structure has been created this way, the recently created documentation manual is ready to receive new sectioning levels (e.g., parts, chapters, sections, etc.). For example, to create a new chapter named Turtles inside My Zoo documentation manual, run the following command: centos-art help --edit --format="texinfo" "myzoo::turtles:" The following documentation chapter doesn't exist: --> trunk/Documentation/Models/Texinfo/MyZoo/en_US/Turtles Do you want to create it now? [yes/no]: yes Enter chapter's title: Turtles Creating trunk/Documentation/Models/Texinfo/MyZoo/en_US/Turtles Creating trunk/Documentation/Models/Texinfo/MyZoo/en_US/Turtles/chapter-menu.texinfo Creating trunk/Documentation/Models/Texinfo/MyZoo/en_US/Turtles/chapter-nodes.texinfo Creating trunk/Documentation/Models/Texinfo/MyZoo/en_US/Turtles/chapter.texinfo Updating trunk/Documentation/Models/Texinfo/MyZoo/en_US/myzoo-menu.texinfo Updating trunk/Documentation/Models/Texinfo/MyZoo/en_US/myzoo-nodes.texinfo Updating trunk/Documentation/Models/Texinfo/MyZoo/en_US/Turtles/chapter.texinfo Updating trunk/Documentation/Manuals/Texinfo/MyZoo/en_US/myzoo.info.bz2 Updating trunk/Documentation/Manuals/Texinfo/MyZoo/en_US/myzoo.xhtml.tar.bz2 Updating trunk/Documentation/Manuals/Texinfo/MyZoo/en_US/myzoo.xml Updating trunk/Documentation/Manuals/Texinfo/MyZoo/en_US/myzoo.docbook Updating trunk/Documentation/Manuals/Texinfo/MyZoo/en_US/myzoo.pdf Updating trunk/Documentation/Manuals/Texinfo/MyZoo/en_US/myzoo.txt.bz2 Once chapters have been created it is possible to create sections inside them. For example, if you want to create a section for describing the life of a turtle named Longneck, run the following command: centos-art help --edit --format="texinfo" "myzoo::turtles:longneck" The following documentation section doesn't exist: --> trunk/Documentation/Models/Texinfo/MyZoo/en_US/Turtles/longneck.texinfo Do you want to create it now? [yes/no]: yes Creating trunk/Documentation/Models/Texinfo/MyZoo/en_US/Turtles/longneck.texinfo Updating trunk/Documentation/Manuals/Texinfo/MyZoo/en_US/myzoo.info.bz2 Updating trunk/Documentation/Manuals/Texinfo/MyZoo/en_US/myzoo.xhtml.tar.bz2 Updating trunk/Documentation/Manuals/Texinfo/MyZoo/en_US/myzoo.xml Updating trunk/Documentation/Manuals/Texinfo/MyZoo/en_US/myzoo.docbook Updating trunk/Documentation/Manuals/Texinfo/MyZoo/en_US/myzoo.pdf Updating trunk/Documentation/Manuals/Texinfo/MyZoo/en_US/myzoo.txt.bz2 To edit documentation entries you can follow the same procedure described above. Just keep in mind the following rules: When the entry you want to edit already exist it will be edited. When the entry you want to edit doesn't exist it will be created first and edited later. Consider a new turtle named Slowfeet has arrived to your home and you want to duplicate Longneck's section for it (they both are turtles and have similar requirements, squedules, etc.). To copy documentation entries you use the --copy option with two documentation entries, where the first one is the source location and the second one the target location. This need can be covered with the following command: centos-art help --copy --format="texinfo" "myzoo::turtles:longneck" "myzoo::turtles:slowfeet" Creating trunk/Documentation/Models/Texinfo/Myzoo/en_US/Turtles/slowfeet.texinfo Updating trunk/Documentation/Models/Texinfo/Myzoo/en_US/Turtles/slowfeet.texinfo Updating trunk/Documentation/Manuals/Texinfo/Myzoo/en_US/myzoo.info.bz2 Updating trunk/Documentation/Manuals/Texinfo/Myzoo/en_US/myzoo.xhtml.tar.bz2 Updating trunk/Documentation/Manuals/Texinfo/Myzoo/en_US/myzoo.xml Updating trunk/Documentation/Manuals/Texinfo/Myzoo/en_US/myzoo.docbook Updating trunk/Documentation/Manuals/Texinfo/Myzoo/en_US/myzoo.pdf Updating trunk/Documentation/Manuals/Texinfo/Myzoo/en_US/myzoo.txt.bz2 In order to copy documentation entries successfully, the source documentation entry must not contain any pending change. Otherwise, the target section won't be created and the script will immediatly stop its execution with a The source location has pending changes. error message. To delete one documentation entry, use the following command: centos-art help --delete --format="texinfo" "manual:part:chapter:section" ... To rename one documentation entry, use the following command: centos-art help --copy --format="texinfo" "manual:part:chapter:section" "manual:part:chapter:section" ... ...
