NCARG_ENV(5NCARG)

💖 NAME 💖

okay so bestie, this page is all about the NCAR Graphics environment variables — every single one, alphabetically, and what it actually does. buckle up 🎀

✨ SYNOPSIS ✨

what follows is the alphabetical list of every NCAR Graphics environment variable and what it means. no cap, all of them 💅

• NCARG_BIN — if you set it, it says where the NCAR Graphics binaries are installed. this one takes precedence over NCARG_ROOT, and honestly you don't even need to set it unless you wanna override the default, which is $NCARG_ROOT/bin.
• NCARG_CONFIG — if you set it, it says where the NCAR Graphics configuration files live. heads up: these are needed by site installers only 🙈. takes precedence over NCARG_ROOT, and you don't need to set it unless you wanna override the default $NCARG_ROOT/lib/ncarg/config.
• NCARG_DATA — if you set it, it says where the NCAR Graphics example data files are installed. takes precedence over NCARG_ROOT, and no need to set it unless you're overriding the default $NCARG_ROOT/lib/ncarg/data.
• NCARG_DATABASE — if you set it, it says where the NCAR Graphics database files are installed. takes precedence over NCARG_ROOT, don't set it unless you wanna override the default $NCARG_ROOT/lib/ncarg/database.
• NCARG_DOC — if you set it, it says where the NCAR Graphics PostScript documentation is installed. takes precedence over NCARG_ROOT, only set it if you're overriding the default $NCARG_ROOT/lib/ncarg/doc.
• NCARG_EXAMPLES — if you set it, it says where some of the NCAR Graphics examples are installed. takes precedence over NCARG_ROOT, and you only need it if you wanna override the default $NCARG_ROOT/lib/ncarg/examples.
• NCARG_FONTCAP — if you set it, it says which NCAR Graphics fontcap should be used as the default one. ✨
• NCARG_FONTCAPS — if you set it, it says where the NCAR Graphics fontcaps are installed. takes precedence over NCARG_ROOT, and it's optional unless you're overriding the default $NCARG_ROOT/lib/ncarg/fontcaps.
• NCARG_GKS_BUFSIZE — this one hands you control over how CGM output gets buffered. 🫶
• NCARG_GKS_DEBUG — if you set it, you get debugging info about the GKS I/O subsystem printed out to stdout. very "let me see what's going on" energy.
• NCARG_GKS_GENCGM — this lets you request that the NCAR GKS package generate binary encoded CGM instead of NCGM (which is the NCAR private encoding of binary encoded CGM). the way that's a whole mouthful 😭
• NCARG_GKS_OUTPUT — lets you specify what file or process the CGM output gets directed to.
• NCARG_GKS_PSOUTPUT — lets you specify what file any PostScript output from NCAR GKS gets directed to. (stdout is allowed! 💅)
• NCARG_GKS_PDFOUTPUT — lets you specify what file any PDF output from NCAR GKS gets directed to. (stdout is allowed here too ✨)
• NCARG_GRAPHCAP — if you set it, it says which NCAR Graphics graphcap should be used as the default.
• NCARG_GRAPHCAPS — if you set it, it says where the NCAR Graphics graphcaps are installed. takes precedence over NCARG_ROOT, and it's optional unless you wanna override the default $NCARG_ROOT/lib/ncarg/graphcaps.
• NCARG_HLUEX — if you set it, it says where the NCAR Graphics HLU examples are installed. takes precedence over NCARG_ROOT, only needed if you're overriding the default $NCARG_ROOT/lib/ncarg/hluex.
• NCARG_INCLUDE — if you set it, it says where the NCAR Graphics include files are installed. takes precedence over NCARG_ROOT, and no need to set it unless you're overriding the default $NCARG_ROOT/include.
• NCARG_LIB — if you set it, it says where the NCAR Graphics libraries are installed. takes precedence over NCARG_ROOT, don't bother unless you wanna override the default $NCARG_ROOT/lib.
• NCARG_MAN — if you set it, it says where the NCAR Graphics man pages are installed. takes precedence over NCARG_ROOT, and it's optional unless you're overriding the default $NCARG_ROOT/man. (yes bestie, the very pages you're reading 💖)
• NCARG_NCARG — if you set it, it says where the NCAR Graphics examples, databases, resource files, etc. are installed. takes precedence over NCARG_ROOT, and you only need it if you're overriding the default $NCARG_ROOT/lib/ncarg.
• NCARG_NCLEX — if you set it, it says where the NCAR Graphics NCL examples are installed. takes precedence over NCARG_ROOT, optional unless you're overriding the default $NCARG_ROOT/lib/ncarg/nclex.
• NCARG_NGURL — if you set it, it says where the file that contains the URL to the NCAR Graphics documentation is installed. takes precedence over NCARG_ROOT, and no need unless you're overriding the default $NCARG_ROOT/lib/ncarg/ngwww/ngurl.
• NCARG_NGWWW — if you set it, it says where the NCAR Graphics HTML documentation is installed. takes precedence over NCARG_ROOT, optional unless you're overriding the default $NCARG_ROOT/lib/ncarg/ngwww.
• NCARG_RESFILES — if you set it, it says where the NCAR Graphics resource files are installed. takes precedence over NCARG_ROOT, and you only need it if you're overriding the default $NCARG_ROOT/lib/ncarg/resfiles.
• NCARG_ROOT — this one says the parent directory where all the NCAR Graphics binaries, libraries, include files, man pages, examples, etc. are installed. this is the big one, bestie 👑

this environment variable must be set by anybody who wants to run NCAR Graphics. (or, alternatively, you can optionally set NCARG_LIB, NCARG_BIN, and NCARG_INCLUDE instead.)

• NCARG_SYSRESFILE — if you set it, it says where the NCAR Graphics system resource file is installed. takes precedence over NCARG_ROOT, optional unless you're overriding the default $NCARG_ROOT/lib/ncarg/sysappres.
• NCARG_TESTS — if you set it, it says where the NCAR Graphics test examples are installed. takes precedence over NCARG_ROOT, only needed if you're overriding the default $NCARG_ROOT/lib/ncarg/tests.
• NCARG_TMP — if you set it, it says where NCAR Graphics temporary files should be written. 🍓
• NCARG_TUTORIAL — if you set it, it says where the NCAR Graphics tutorial examples are installed. takes precedence over NCARG_ROOT, and it's optional unless you're overriding the default $NCARG_ROOT/lib/ncarg/tutorial.
• NCARG_USRRESFILE — if you set it, it says where the NCAR Graphics user resource file is installed. this one does not have the NCARG_ROOT precedence thing going on — you don't need to set it unless you wanna override the default ~/.hluresfile. 🌸
• NCARG_XAPP — if you set it, it says where the NCAR Graphics X application default files are installed. takes precedence over NCARG_ROOT, and no need unless you're overriding the default $NCARG_ROOT/lib/ncarg/xapp.
