IRAF CL Script |
https://www.adc.nao.ac.jp/J/cc/public/koshu_shiryo/2010/IRAF2010-1/iraf2010-1_yoshida.pdf |
新規 CL script 1. procedure宣言 2. 明示パラメータ(スクリプト引数)宣言 3. (隠れパラメータ宣言) 4. (list directed parameters宣言) 5. begin 6. スクリプトの中身 7. endタスクの登録法 ecl> task mytask = mytask.cl task登録のとき”$”は無し←パラメータ(明示and/or隠れ)がスクリプト中にあるから ecl> redefine mytask = mytask.cl |
ホストの環境変数を参照する: osfn() |
file 出力: 1) (初期化出力) sections(infile, option=“fullname”, > tmpfile) 2) (追記) print( param, >> outfiles ) |
scan ( p1, p2, ... ) : 標準入力から読み取って内部変数p1, p2, ... , に格納 |
fscan( pp, p1, p2, ... ) : 内部変数ppから読み取って別の内部変数, p1, p2, ... , に格納 |
IRAFコマンドの出力を内部変数に格納する ecl> real x1, x2 ecl> imstat img/MT8191.fits field=“min,max” format-| scan( x1, x2 ) |
mktemp mktemp : 一時使用ファイル(temporary file)を作るコマンド ・ファイル名を自動生成する ecl> tmpfile= mktemp( “ppp.” ) : ppp.xxxx(xxxxは数字)というファイル名が自動生成されてtmpfileにアサインされる。 ecl> string tmpfile ecl> tmpfile= mktemp( “ppp.” ) ecl> =tmpfile ecl> print(“hello”, > tmpfile) ecl> lsecl> del (tmpfile) ecl> imcopy(“img/MT8191.fits”, tmpfile) ecl> ls ecl> imdel(tmpfile) |
list directed parameters(LDP) : テキストファイルの中身を、改行で区切られた文字列の順序リストとして格納してくれる CLスクリプト中での宣言:必ずbeginの前で、struct *pppあるいはstring *ppp テキストファイルをLDPに格納するやり方 ppp = file_name CLスクリプト中でファイルの中身を順序読み出しするときは、必ずこれを使う ecl> struct *tlist ecl> tlist = “table1” ecl> while (fscan (tlist, s1) != EOF) { print(s1) } |
ワイルドカードとsectionsコマンド IRAFでのワイルドカード *、?などのふつうのUNIXワイルドカードと、@付きファイルリスト IRAFワイルドカードはsectionsコマンドで展開して標準出力に書き出す sections( “*.fits”, option=“full”) sections( “@list”, option=“root”) |

IRAF CL Script sample
!xpaset(), !xpaget() で CL Script 内で xpaset/xpaget() が使えそう。 |
Modified display2.cl using xpaset(), as oiginal display cannot be shown the header correctly but image display is OK.
