# changelog(3tcl)

Processing text in Emacs ChangeLog format

```

```

## NAME

doctools::changelog - Processing text in Emacs ChangeLog format

## SYNOPSIS

package require **Tcl 8.5 9**

package require **textutil**

package require **doctools::changelog ?1.2?**

**::doctools::changelog::scan** *text*

**::doctools::changelog::flatten** *entries*

**::doctools::changelog::toDoctools** *title* *module* *version* *entries*

**::doctools::changelog::merge** *entries*...

```

```

## DESCRIPTION

This package provides Tcl commands for the processing and reformatting of text in the "*ChangeLog*" format generated by **emacs**.

## API

- **::doctools::changelog::scan** *text*

  The command takes the *text* and parses it under the assumption that it contains a ChangeLog as generated by **emacs**. It returns a data structure describing the contents of this ChangeLog.

  This data structure is a list where each element describes one entry in the ChangeLog. Each element/entry is then a list of three elements describing the date of the entry, its author, and the comments made, in this order. The last item in each element/entry, the comments, is a list of sections. Each section is described by a list containing two elements, a list of file names, and a string containing the true comment associated with the files of the section.

  ```
      {
  	{
  	    date
  	    author
  	    {
  		{
  		    {file ...}
  		    commenttext
  		}
  		...
  	    }
  	}
  	{...}
      }
  ```

- **::doctools::changelog::flatten** *entries*

  This command converts a list of entries as generated by **change::scan** above into a simpler list of plain text blocks each containing all the information of a single entry.

- **::doctools::changelog::toDoctools** *title* *module* *version* *entries*

  This command converts the pre-parsed ChangeLog *entries* as generated by the command **::doctools::changelog::scan** into a document in *doctools* format and returns it as the result of the command.

  The other three arguments supply the information for the header of that document which is not available from the changelog itself.

- **::doctools::changelog::merge** *entries*...

  Each argument of the command is assumed to be a pre-parsed Changelog as generated by the command **::doctools::changelog::scan**. This command merges all of them into a single structure, and collapses multiple entries for the same date and author into a single entry. The new structure is returned as the result of the command.
