* The gf command line options -preproc=mkPresent and -preproc=mkMinimal now
refer to internal preprocessors equivalent to lib/src/mkPresent
and lib/src/mkMinimal.
* The temporary file _gf_preproc.tmp is not created when running an
internal preprocessor, unless there is an error, since errors messages
refer to locations in the preprocessed file. (Possibly allowing the rgl
build to be parallelized.)
* After running an external preprocessor, the temporary file is deleted,
unless there was an error.
* (Bug fix) Before, when running more than one preprocessor, the same file name
would be used for both input and output, e.g.,
mkPresent _gf_preproc.tmp > _gf_preproc.tmp
which would result in an empty file being processed. Now, the input and
output files will always be different.
The dependency on the fastcgi package made pgf-server difficult to compile, so
it is now split into
- pgf-fgci (main module in pgf-fcgi.hs), which is built only if fastcgi is
already installed or if you turn on the fastcgi flag (e.g. by doing
'cabal install -f fastcgi').
- pgf-http (main module in pgf-http.hs) which is always built (and hopefully
has no problematic dependencies.)
The modules FastCGIUtils and PGFService no longer depend on fastcgi.
+ PGFService.hs: add Nothing arguments in calls to PGF.parse_ and
PGF.getPArseOutput
+ gf-server.cabal: mark content-server as not buildable, since required source
files are missing.
* Keyboard input and completion should now work much more smoothly:
+ When you press space, the current word will be completed (if incomplete)
and a new magnet will be created. If there is more than one possible
completion, no magnet is created, but the common prefix of the possible
completions is added to the text box.
+ Instead of asking the server for possible completions every time a new
letter is added to the curent word, minibar only ask for completions for
whole words and then filters the list locally when more letters are entered,
speeding things up when server responses are slow.
* Code restructuring:
+ The PGF server API has been moved to its own file: pgf_online.js. This
allows it to be reused in other applicaitons without importing the entire
minibar. It also allows minibar to be used with different server interfaces.
+ The minibar code has been rewritten to avoid storing state information
in the document tree and accessing it by referring to named document
elements. The code now also avoids using string literals contaning
the names of top-level functions to specify event handlers for buttons
and menus. (The code is no longer introspective, so alpha conversion will
not change its meaning.)
+ ajax_http_get(url,callback) now checks the HTTP response status and shows an
error message if the status is not OK (is not 200)
+ New function node(tag,attrs,children) to create document nodes with arbitraty
attributes and children. The functions node() and text() should now be enough
to construct arbitrary document trees in an easy, functional way, and many of
the more specialized functions could be removed.
+ When calling the function button(label,action,key), the action can be a
function instead of a string, so you can use local/anonymous functions.
+ New function debug(str) adds text to the element with id=debug, if it
exists.
