# TEPAM - Tcl's Enhanced Procedure and Argument Manager

#### Initialization ####
DemoControl(Initialization) 1
DemoControl(IsExecutable) {0}
# This demo gives a very short overview about the major features of the
# advanced procedure and argument manager. This basically includes:
# - Procedure declaration
# - Interactive procedure help query
# - Procedure call with several argument definition variations
# - Interactive procedure call and argument definitions
package require Tk
package require tepam
namespace import -force tepam::*; # Import tepam::procedure and tepam::argument_dialogbox
#### Procedure definition ####
DemoControl(IsExecutable) {[info commands {display message}]=={}}
# This first example section declares the sub procedure 'display message' that has
# several arguments. The last one is an unnamed argument while the others are named
# arguments.
procedure {display message} {
-return -
-short_description "Displays a simple message box"
-description "This procedure allows displaying a configurable message box."
-args {
{-mtype -default Warning -choices {Info Warning Error} -description "M. type"}
{-font -type font -default {Arial 10 italic} -description "Message font"}
{-level -type integer -optional -range {1 10} -description "Message level"}
{-fg -type color -default black -description "Message color"}
{-bg -type color -optional -description "Background color"}
{-no_border -type none -description "Use a splash window style (no border)"}
{-log_file -type file -optional -description "Optional message log file"}
{text -type string -multiple -description "Multiple text lines to display"}
}
-example {
display message "The document hasn't yet been saved!"
display message -fg red -bg black "Please save first the document"
}
} {
puts "display message:"
foreach var {mtype font level fg bg no_border log_file text} {
if {[info exists $var]} {
puts " $var=[set $var]"
}
}
}
#### Procedure help ####
DemoControl(IsExecutable) {[info commands {display message}]!={} && !$Executed}
# Simply call de declared procedure with the -help option to get the information to
# the procedure and its arguments.
display message -help
#### Correct procedure calls ####
DemoControl(IsExecutable) {[info commands {display message}]!={} && !$Executed}
# The specified procedure can be called in many ways:
display message "The document hasn't yet been saved!"
display message -fg red -bg black "Please save first the document"
display message -mtype Error -no_border "Why is here no border?"
display message -font {Courier 12} -level 10 "Is there enough space?" "Reduce otherwise the font size!"
#### Incorrect procedure calls ####
DemoControl(IsExecutable) {[info commands {display message}]!={} && !$Executed}
# The next lines show how wrong arguments specifications are recognized.
# The argument 'text' is mandatory:
display message -font {Courier 12}
# Unknown options are leading to an error:
display message -category warning "Hello"
# The argument types are automatically checked. For example the colors:
display message -fg MyColor "Hello"
# Choice lists have to be respected:
display message -mtype "Fatal" "Hello"
# Ranges have to be respected:
display message -level 12 "Hello"
#### Interactive procedure call ####
DemoControl(IsExecutable) {[info commands {display message}]!={}}
# The most intuitive way to call the procedure is using an interactive form that allows
# specifying all arguments. This form will automatically be opened when the declared
# procedure is called with the -interactive option.
display message -interactive
#### Documentation generation ####
DemoControl(IsExecutable) {[info commands {display message}]!={}}
# The TEPAM documentation generation package allows generating documentation for the
# specified procedures in various formats. This demo section opens a dialog box to
# define the document name, and generates then the documentation based on the
# specified file format.
# Load TEPAM Doc Gen package
package require tepam::doc_gen
# Get the document file name
set DocFile [tk_getSaveFile \
-filetypes {{Text *.txt} {HTML *.html} {POD *.pod} {"Tcllib doctools" *.dt}}]
# Extract the document type
set DocFormat [string toupper [string range [file extension $DocFile] 1 end]]
# Generate the document. In case of a HTML document copy also the CSS stylesheet
# to the document destination folder. In case of an unknown document type
# generate an error message.
if {$DocFile!=""} {
if {[lsearch -exact {TXT HTML POD DT} $DocFormat]<0} {
tk_messageBox -message "Extension '$DocFormat' of file '$DocFile' unknown!\
Chose either extension .txt, .html, .pod or .dt"
} else {
tepam::doc_gen::generate -format $DocFormat -dest_file $DocFile {display message}
if {$DocFormat=="HTML"} {
file copy -force [pwd]/tepam_doc_stylesheet.css [file dirname $DocFile]
}
}
