Type and .\" name are examples of largest possible arguments that will be passed .\" to .AP later. If args are omitted, default tab stops are used. .\" .\" .BS .\" Start box enclosure.

.sp .BE .SH DESCRIPTION The \fBctext\fR package provides the ctext widget which is an enhanced text widget with support for configurable syntax highlighting and some extra commands\&. .PP Ctext overloads the text widget and provides new commands, named \fBhighlight\fR, \fBcopy\fR, \fBpaste\fR,\fBcut\fR, \fBappend\fR, and \fBedit\fR\&. It also provides several commands that allow you to define classes\&. Each class corresponds to a tag in the widget\&. .SH COMMANDS .TP \fBctext\fR \fIpathName\fR ?\fIoptions\fR? Creates and configures a ctext widget\&. .PP .SH HIGHLIGHTING Highlighting is controlled with text widget tags, that are called highlight classes\&. The \fIclass\fR is a tag name and can be configured like any text widget tag\&. Four types of highlight classes are supported\&. All highlight classes are automatically used by the \fBhighlight\fR method of the widget\&. .TP \fB::ctext::addHighlightClass\fR \fIpathName\fR \fIclass\fR \fIcolor\fR \fIkeywordlist\fR Add a highlighting class \fIclass\fR to the ctext widget \fIpathName\fR\&. The highlighting will be done with the color \fIcolor\fR\&. All words in the \fIkeywordlist\fR will be highlighted\&. .CS # highlight some tcl keywords ::ctext::addHighlightClass \&.t tclkeywords red [list set info interp uplevel upvar] .CE .TP \fB::ctext::addHighlightClassWithOnlyCharStart\fR \fIpathName\fR \fIclass\fR \fIcolor\fR \fIchar\fR Add a highlighting class \fIclass\fR to the ctext widget \fIpathName\fR\&. The highlighting will be done with the color \fIcolor\fR\&. All words starting with \fIchar\fR will be highlighted\&. .CS ::ctext::addHighlightClassWithOnlyCharStart \&.t vars blue \\$ .CE .TP \fB::ctext::addHighlightClassForSpecialChars\fR \fIpathName\fR \fIclass\fR \fIcolor\fR \fIcharstring\fR Add a highlighting class \fIclass\fR to the ctext widget \fIpathName\fR\&. The highlighting will be done with the color \fIcolor\fR\&. All chars in \fIcharstring\fR will be highlighted\&. .TP \fB::ctext::addHighlightClassForRegexp\fR \fIpathName\fR \fIclass\fR \fIcolor\fR \fIpattern\fR Add a highlighting class \fIclass\fR to the ctext widget \fIpathName\fR\&. The highlighting will be done with the color \fIcolor\fR\&. All text parts matching the regexp \fIpattern\fR will be highlighted\&. .TP \fB::ctext::clearHighlightClasses\fR \fIpathName\fR Remove all highlight classes from the widget \fIpathName\fR\&. .TP \fB::ctext::getHighlightClasses\fR \fIpathName\fR List all highlight classes for the widget \fIpathName\fR\&. .TP \fB::ctext::deleteHighlightClass\fR \fIpathName\fR \fIclass\fR Delete the highlight class \fIclass\fR from the widget \fIpathName\fR .TP \fB::ctext::enableComments\fR \fIenable\fR Enable C comment highlighting\&. The \fIclass\fR for c-style comments is \fB_cComment\fR\&. The C comment highlighting is disabled by default\&. .TP \fB::ctext::disableComments\fR \fIenable\fR Disable C comment highlighting\&. .PP .SH "WIDGET COMMANDS" Each ctext widget created with the above command supports the following commands and options in addition to the standard text widget commands and options\&. .TP \fIpathName\fR \fBhighlight\fR \fIstartIndex\fR \fIendIndex\fR Highlight the text between \fIstartIndex\fR and \fIendIndex\fR\&. .TP \fIpathName\fR \fBfastdelete\fR \fIindex1\fR ?\fIindex2\fR? Delete text range without updating the highlighting\&. Arguments are identical to the \fIpathName\fR \fBdelete\fR command inherited from the standard text widget\&. .TP \fIpathName\fR \fBfastinsert\fR Insert text without updating the highlighting\&. Arguments are identical to the \fIpathName\fR \fBinsert\fR command inherited from the standard text widget\&. .TP \fIpathName\fR \fBcopy\fR Call \fBtk_textCopy\fR for the ctext instance\&. .TP \fIpathName\fR \fBcut\fR Call \fBtk_textCut\fR for the ctext instance\&. .TP \fIpathName\fR \fBpaste\fR Call \fBtk_textPaste\fR for the ctext instance\&. .TP \fIpathName\fR \fBappend\fR Append the current selection to the clipboard\&. .TP \fIpathName\fR \fBconfigure\fR \fIoption\fR \fIvalue\fR ?\&.\&.\&.? Set the options for the ctext widget\&. Each option name must be followed the new value\&. .PP .SH "WIDGET OPTIONS" .LP .nf .ta 6c Command-Line Switch: \fB-linemap\fR Database Name: \fB\fR Database Class: \fB\fR .fi .IP Creates (-linemap 1) or deletes (-linemap 0) a line number list on the left of the widget\&. The default is to have a linemap displayed\&. .LP .nf .ta 6c Command-Line Switch: \fB-linemapfg\fR Database Name: \fB\fR Database Class: \fB\fR .fi .IP Changes the foreground of the linemap\&. The default is the same color as the main text widget\&. .LP .nf .ta 6c Command-Line Switch: \fB-linemapbg\fR Database Name: \fB\fR Database Class: \fB\fR .fi .IP Changes the background of the linemap\&.
