Add --new-script option to gmt

[PaulWessel]

This option will write a modern mode script template to stdout in either bash or csh format. We could extend this to DOS batch if we can detect the Windows command window (?). Not tested by a user whose default shell is csh or tcsh.

[PaulWessel]

Partially addresses the issues raised in #1299.

[joa-quim]

Yes, DOS batch should be a possible output too. On Win most of times a .bat is all one needs.

[PaulWessel]

How do we know one is running gmt under Windows command window (and want a batch) rather than in a bash shell?

[joa-quim]

Well, under Win one should default to .bat. But we can print also the unix shebang line but commented out. Like this a Win user that wants a bash can easily uncomment that line and comment the @echo off one.

[PaulWessel]

I guess if Windows and if getenv ("shell") or getenv ("SHELL") are not defined then we are likely in Windows command window. What does echo %SHELL% or echo %shell% give you, if anything?

[seisman]

%SHELL% and %shell% give nothing.

[PaulWessel]

OK, so presumably that is a good test to run under #ifdef WINDOWs and if none are set then we write a batch script.

[PaulWessel]

See what you guys think. I cannot easily test apart from bash.

[joa-quim]

Busy with the proj.db shit.

This is what I get with Windows CMD.

REM GMT modern mode batch template
REM Date:    2019-09-02T22:36:58
REM User:    unknown
REM Purpose: Purpose of this script
REM Set a unique session name:
set GMT_SESSION_NAME 5372
gmt begin figurename
        REMPlace modern session commands here
gmt end show

There are at least two errors here, and I've made the suggestions.

[PaulWessel]

OK, I fixed those two. Updated gmt_putusername to work under Windows - please test.

Bash on macOS:

#!/usr/bin/env bash
# GMT modern mode bash template
# Date:    2019-09-02T22:50:24
# User:    seisman
# Purpose: Purpose of this script
export GMT_SESSION_NAME=$$	# Set a unique session name
gmt begin figurename
	# Place modern session commands here
gmt end show

csh on macOS:

#!/usr/bin/env csh
# GMT modern mode csh template
# Date:    2019-09-02T23:29:14
# User:    seisman
# Purpose: Purpose of this script
setenv GMT_SESSION_NAME $$	# Set a unique session name
gmt begin figurename
	# Place modern session commands here
gmt end show

CMD on Windows:

REM GMT modern mode batch template
REM Date:    2019-09-02T23:34:25
REM User:    unknown
REM Purpose: Purpose of this script
REM Set a unique session name:
set GMT_SESSION_NAME=7492
gmt begin figurename
        REM Place modern session commands here
gmt end show

Git-Bash on Windows:

#!/usr/bin/env bash
# GMT modern mode bash template
# Date:    2019-09-02T23:35:36
# User:    unknown
# Purpose: Purpose of this script
export GMT_SESSION_NAME=$$      # Set a unique session name
gmt begin figurename
        # Place modern session commands here
gmt end show

Looks good, except the username is still unknown on Windows.

[PaulWessel]

Does echo %USERNAME% give anything useful in Windows?

[seisman]

Yes, %USERNAME% gives the correct username in CMD, and also $USERNAME in git-bash.

[seisman]

Now the username is correct on Windows.

[joa-quim]

Again, you wee too quick with the trigger. A batch file should always start with a line @echo off Otherwise it prints all its contents which very annoying. Also, I wouldn’t print the user not the purpose lines. It just makes the template too heavy. If user wants that type of info, let him add it.
