4.2: 2013-02-16

• Added the new variables `gams-outline-regexp-font-lock’ and `gams-level-color-stars-only’.
  With this chage, headlines are colored according to their level. See Screenshot Page.

GAMS mode for Emacs version 4.1 is released.

4.1: 2012-10-13

• Fixed minor bugs.
• Changed the explanation in BUGS_PROBLEMS.txt and README.txt. Until the
  previous version, I recommended to add the following setting to Emacs.

    (setq jit-lock-chunk-size 50000)
  

  This is for making coloring in GAMS mode work well. But now I recommend
  the following setting:

    (setq font-lock-support-mode '((gams-mode . nil) (t . jit-lock-mode)))
  

  This means that font-lock-support-mode is not used in GAMS mode. By
  this setting, Emacs is likely to slow down when you open GAMS files, but
  you will encounter less troubles in coloring of GAMS mode.

• Abolished the command `gams-outline-external’ (and deleted files
  associated with this command).

• Made several changes on GAMS-SIL mode.

  We often include the same file many times in a program. For example,
  supose that a GAMS program includes the following codes.

    $batinclude aggr vst i r vst_
    $batinclude aggr vtwr i j r s vtwr_
    $batinclude aggr vom g r vom_
  

  In this code, aggr.gms is included repeatedly. In the previous GAMS-SIL
  model, the content of aggr.gms is expanded repeatedly in GAMS-SIL
  buffer. But in the new gams.el, aggr.gms is expanded only once (only
  first time).

• Added a new new function `gams-sil-toggle-expand-file-more’ and a lisp
  variable `gams-sil-expand-file-more’ (the default value is nil).

  In GAMS-SIL mode, the contents of files included by $include commands
  are usually expanded. For example, if your program includes the
  following code:

    $include zzz.gms
  

  then, the content of zzz.gms above is always expanded in
  GAMS-SIL. However, if the file is included conditionally like

    $if exist xxx.gms $include xxx.gms
    $if %scenario%="bau" $include xxx.gms
  

  the content of xxx.gms is not expanded by default.

  If you want to expand the content of conditionally inluced files, type
  “x” in GAMS-SIL buffer. This evokes `gams-sil-toggle-expand-file-more’
  command.

  If you always want to expand the content of conditionally inluced files,
  then set non-nil to the lisp variable `gams-sil-expand-file-more’.

• Added the new lisp variable `gams-sil-expand-batinclude’ (default value is t).

  In GAMS-SIL mode, the contents of files included by $include commands
  are always expanded. But files included by $batinclude are not expanded
  if `gams-sil-expand-batinclude’ is nil.

• Changed the default value of `gams-special-comment-symbol’ from “com:”
  to “@”. This is the string to specify the special comment like

    display "@ This is the special comment line";
  

  The special comment line is used for headlines in GAMS-SIL mode and
  GAMS-OUTLINE mode.

• Added outline representation like Org-mode (or outline mode). You can
  only show headlines of a GAMS program.

  By default, lines starting with *@ are regarded as headlines.

    *@ 	The top level headline
    *@@ 	Second level
          text text
    *@@@ 	Third level
          text text
    *@ 	Another top level headline
  

  You can change outline representation by the following two commands:

  • `org-cycle’ (binded to TAB key)
  • `org-global-cycle’ (binded to Shift+TAB key).

  `org-cycle’ command works only on headlines and toggles hide/show the
  body of programs. `org-global-cycle’ toggles hide/show entire program.

  Open a sample file “org-minor-mode.gms” and try TAB and Shift+TAB.

  This feature uses codes in Org-mode. So if you want to use this feature,
  Org-mode must be installed (The recent Emacs has Org-mode by
  default). In addition, note that this command may depend on the version
  of Org-mode. I test in Org-mode of 7.8.11.

  [How to change symbols for headlines]

  In the default setting, “*@” is used as symbols to represent
  headlines. This is determined by the lisp variable
  `gams-outline-regexp’. This variable specifies the regular expressions
  of the symbol used to represent headlines and its default value is

    "\\*@+[ \t]"
  

  If you change the value of this variable, you can change symbols for
  headlines. For example, add the following expression to your init.el
  file

    (setq gams-outline-regexp "[ \t]*display \"@+[ \t]")
  

  And open “org-minor-mode-alt.gms”.

  [Other commands for outline handling]

  • “C-cC-:n” -> Move to the next headlines (`outline-next-visible-heading’).
  • “C-cC-:p” -> Move to the previous headlines (`outline-previous-visible-heading’).
  • “C-cC-:f” -> Fold the current tree (`gams-org-fold-current-tree’).
  • “C-cC-:k” -> Show branches (`show-branches’).
• Changed the default indent number from 8 to 4.
• Changed the name of sample setting file from “dot-emacs-sample” to
  “setting-sample.el”.

GAMS mode for Emacs version 3.6.6 is released. This is a bug fix release.

• Quited supporting XEmacs because I have no environment for testing
  XEmacs.
• Increased the default value of `gams-lxi-maximum-line’ (from 500000 to
  1000000).
• Fixed a bug in `gams-show-identifier’.
• Fixed many minor bugs.
