The report objects defined here break each report down into three [REGIONS](#section2) and ten classes of *[lines](\.\./\.\./\.\./\.\./index\.md\#lines)* \(various separator\- and data\-lines\)\. See the following section for more detailed explanations\. - __::report::report__ *reportName* *columns* ?__style__ *style arg\.\.\.*? Creates a new report object for a report having *columns* columns with an associated global Tcl command whose name is *reportName*\. This command may be used to invoke various configuration operations on the report\. It has the following general form: * __reportName__ *option* ?*arg arg \.\.\.*? *Option* and the *arg*s determine the exact behavior of the command\. See section [REPORT METHODS](#section6) for more explanations\. If no __style__ is specified the report will use the builtin style __plain__ as its default configuration\. - __::report::defstyle__ *styleName arguments script* Defines the new style *styleName*\. See section [STYLES](#section5) for more information\. - __::report::rmstyle__ *styleName* Deletes the style *styleName*\. Trying to delete an unknown or builtin style will result in an error\. Beware, this command will not check that there are no other styles depending on the deleted one\. Deleting a style which is still used by another style FOO will result in a runtime error when FOO is applied to a newly instantiated report\. - __::report::stylearguments__ *styleName* This introspection command returns the list of arguments associated with the style *styleName*\. - __::report::stylebody__ *styleName* This introspection command returns the script associated with the style *styleName*\. - __::report::styles__ This introspection command returns a list containing the names of all styles known to the package at the time of the call\. The order of the names in the list reflects the order in which the styles were created\. In other words, the first item is the predefined style __plain__, followed by the first style defined by the user, and so on\. # REGIONS The three regions are the *top caption*, *data area* and *bottom caption*\. These are, roughly speaking, the title, the values to report and a title at the bottom\. The size of the caption regions can be specified by the user as the number of rows they occupy in the matrix to format\. The size of the data area is specified implicitly\. # LINES [TEMPLATES](#section4) are associated with each of the ten line classes, defining the formatting for this kind of line\. The user is able to enable and disable the separator lines at will, but not the data lines\. Their usage is solely determined by the number of rows contained in the three regions\. Data lines and all enabled separators must have a template associated with them\. Note that the data\-lines in a report and the rows in the matrix the report was generated from are *not* in a 1:1 relationship if any row in the matrix has a height greater than one\. The different kinds of lines and the codes used by the report methods to address them are: - __top__ The topmost line of a report\. Separates the report from anything which came before it\. The user can enable the usage of this line at will\. - __topdatasep__ This line is used to separate the data rows in the top caption region, if it contains more than one row and the user enabled its usage\. - __topcapsep__ This line is used to separate the top caption and data regions, if the top caption is not empty and the user enabled its usage\. - __datasep__ This line is used to separate the data rows in the data region, if it contains more than one row and the user enabled its usage\. - __botcapsep__ This line is used to separate the data and bottom caption regions, if the bottom caption is not empty and the user enabled its usage\. - __botdatasep__ This line is used to separate the data rows in the bottom caption region, if it contains more than one row and the user enabled its usage\. - __bottom__ The bottommost line of a report\. Separates the report from anything which comes after it\. The user can enable the usage of this line at will\. - __topdata__ This line defines the format of data lines in the top caption region of the report\. - __data__ This line defines the format of data lines in the data region of the report\. - __botdata__ This line defines the format of data lines in the bottom caption region of the report\. # TEMPLATES Each template is a list of strings used to format the line it is associated with\. For a report containing __n__ columns a template for a data line has to contain "__n__\+1" items and a template for a separator line "2\*__n__\+1" items\. The items in a data template specify the strings used to separate the column information\. Together with the corresponding items in the separator templates they form the vertical lines in the report\. *Note* that the corresponding items in all defined templates have to be of equal length\. This will be checked by the report object\. The first item defines the leftmost vertical line and the last item defines the rightmost vertical line\. The item at index __k__ \("1",\.\.\.,"__n__\-2"\) separates the information in the columns "__k__\-1" and "__k__"\. The items in a separator template having an even\-numbered index \("0","2",\.\.\.\) specify the column separators\. The item at index "2\*__k__" \("0","2",\.\.\.,"2\*__n__"\) corresponds to the items at index "__k__" in the data templates\. The items in a separator template having an odd\-numbered index \("1","3",\.\.\.\) specify the strings used to form the horizontal lines in the separator lines\. The item at index "2\*__k__\+1" \("1","3",\.\.\.,"2\*__n__\+1"\) corresponds to column "__k__"\. When generating the horizontal lines the items are replicated to be at least as long as the size of their column and then cut to the exact size\. # STYLES Styles are a way for the user of this package to define common configurations for report objects and then use them later during the actual instantiation of report objects\. They are defined as tcl scripts which when executed configure the report object into the requested configuration\. The command to define styles is __::report::defstyle__\. Its last argument is the tcl __script__ performing the actual reconfiguration of the report object to obtain the requested style\. In this script the names of all previously defined styles are available as commands, as are all commands found in a safe interpreter and the configuration methods of report objects\. The latter implicitly operate on the object currently executing the style script\. The __arguments__ declared here are available in the __script__ as variables\. When calling the command of a previously declared style all the arguments expected by it have to be defined in the call\. # REPORT METHODS The following commands are possible for report objects: - *reportName* __destroy__ Destroys the report, including its storage space and associated command\. - *reportName* *templatecode* __disable__|__enable__ Enables or disables the usage of the template addressed by the *templatecode*\. Only the codes for separator lines are allowed here\. It is not possible to enable or disable data lines\. Enabling a template causes the report to check all used templates for inconsistencies in the definition of the vertical lines \(See section [TEMPLATES](#section4)\)\. - *reportName* *templatecode* __enabled__ Returns the whether the template addressed by the *templatecode* is currently enabled or not\. - *reportName* *templatecode* __get__ Returns the template currently associated with the kind of line addressed by the *templatecode*\. All known templatecodes are allowed here\. - *reportName* *templatecode* __set__ *templatedata* Sets the template associated with the kind of line addressed by the *templatecode* to the new value in *templatedata*\. See section [TEMPLATES](#section4) for constraints on the length of templates\. - *reportName* __tcaption__ ?*size*? Specifies the *size* of the top caption region as the number rows it occupies in the matrix to be formatted\. Only numbers greater than or equal to zero are allowed\. If no *size* is specified the command will return the current size instead\. Setting the size of the top caption to a value greater than zero enables the corresponding data template and causes the report to check all used templates for inconsistencies in the definition of the vertical lines \(See section [TEMPLATES](#section4)\)\. - *reportName* __bcaption__ *size* Specifies the *size* of the bottom caption region as the number rows it occupies in the matrix to be formatted\. Only numbers greater than or equal to zero are allowed\. If no *size* is specified the command will return the current size instead\. Setting the size of the bottom caption to a value greater than zero enables the corresponding data template and causes the report to check all used templates for inconsistencies in the definition of the vertical lines \(See section [TEMPLATES](#section4)\)\. - *reportName* __size__ *column* ?*number*|__dyn__? Specifies the size of the *column* in the output\. The value __dyn__ means that the columnwidth returned by the matrix to be formatted for the specified column shall be used\. The formatting of the column is dynamic\. If a fixed *number* is used instead of __dyn__ it means that the column has a width of that many characters \(padding excluded\)\. Only numbers greater than zero are allowed here\. If no size specification is given the command will return the current size of the *column* instead\. - *reportName* __sizes__ ?*size\-list*? This method allows the user to specify the sizes of all columns in one call\. Its argument is a list containing the sizes to associate with the columns\. The first item is associated with column 0, the next with column 1, and so on\. If no *size\-list* is specified the command will return a list containing the currently set sizes instead\. - *reportName* __pad__ *column* ?__left__|__right__|__both__ ?*padstring*?? This method allows the user to specify padding on the left, right or both sides of a *column*\. If the *padstring* is not specified it defaults to a single space character\. *Note*: An alternative way of specifying the padding is to use vertical separator strings longer than one character in the templates \(See section [TEMPLATES](#section4)\)\. If no pad specification is given at all the command will return the current state of padding for the column instead\. This will be a list containing two elements, the first element the left padding, the second describing the right padding\. - *reportName* __justify__ *column* ?__left__|__right__|__center__? Declares how the cell values for a *column* are filled into the report given the specified size of a column in the report\. For __left__ and __right__ justification a cell value shorter than the width of the column is bound with its named edge to the same edge of the column\. The other side is filled with spaces\. In the case of __center__ the spaces are placed to both sides of the value and the left number of spaces is at most one higher than the right number of spaces\. For a value longer than the width of the column the value is cut at the named edge\. This means for __left__ justification that the *tail* \(i\.e\. the __right__ part\) of the value is made visible in the output\. For __center__ the value is cut at both sides to fit into the column and the number of characters cut at the left side of the value is at most one less than the number of characters cut from the right side\. If no justification was specified the command will return the current justification for the column instead\. - *reportName* __printmatrix__ *matrix* Formats the *matrix* according to the configuration of the report and returns the resulting string\. The matrix has to have the same number of columns as the report\. The matrix also has to have enough rows so that the top and bottom caption regions do not overlap\. The data region is allowed to be empty\. - *reportName* __printmatrix2channel__ *matrix chan* Formats the *matrix* according to the configuration of the report and writes the result into the channel *chan*\. The matrix has to have the same number of columns as the report\. The matrix also has to have enough rows so that the top and bottom caption regions do not overlap\. The data region is allowed to be empty\. - *reportName* __[columns](\.\./\.\./\.\./\.\./index\.md\#columns)__ Returns the number of columns in the report\. The methods __size__, __pad__ and __justify__ all take a column index as their first argument\. This index is allowed to use all the forms of an index as accepted by the __lindex__ command\. The allowed range for indices is "0,\.\.\.,\[__reportName__ columns\]\-1"\. # EXAMPLES Our examples define some generally useful report styles\. A simple table with lines surrounding all information and vertical separators, but without internal horizontal separators\. ::report::defstyle simpletable {} { data set [split "[string repeat "| " [columns]]|"] top set [split "[string repeat "+ - " [columns]]+"] bottom set [top get] top enable bottom enable } An extension of a __simpletable__, see above, with a title area\. ::report::defstyle captionedtable {{n 1}} { simpletable topdata set [data get] topcapsep set [top get] topcapsep enable tcaption $n } Given the definitions above now an example which actually formats a matrix into a tabular report\.
