GAMS mode (ver.4.0)
GAMS mode for Emacs version 4.0 is released.
http://shirotakeda.org/en/gams/gams-mode.html
- 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 likedisplay "@ 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 headlineYou 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”.
