Re: [Freedos-devel] Question about edlin
That solves the problem with commas, but it looks like you may still have
issues if there are quotes in the file.
I know one thing I've done in the past with some of my programs is allow the
use of either a double-quote ("), single-quote ('), or grave-quote (`) as
string demarkers, which allows strings to contain any two of the three
quote-types and still be able to identify them properly. Of course, it will
still fail if a string contains all three quote types, but that is a rare
situation.
EDLIN's solution (at least for MS-DOS 7.1) solves all potential problems with
Ctrl-Z since Ctrl-Z (end-of-file) should never appear in the middle of the
kinds of files (plain text) that EDLIN works with.

That solves my problem. Thanks! Also can use the same trick to change a comma to something else. Here's another 1-line demo: *1p 1:*period, *1r",","." 1: period. If you can't see it well, that's a 'comma inside double quotes' then a comma, then a 'period inside double quotes.' But really it just needs the quotes about the comma, and only if it's the first comma. Here's an example to change it back again: *1r.,"," 1: period, *1r",",. 1: period. *1r.,, 1: period, That last one changes the period to a comma, and you don't need the double quotes around the second comma in this case.

Re: [Freedos-devel] Question about edlin
It would be great when edlin could support the 20 NLS files that are shipped with it some day. At least 1.24 till 1.29 of the NLS files are not supported. And I do not speak about Chinese.

Re: [Freedos-devel] Question about edlin
FD edlin ignores a leading space. If you want the leading space to be searched for, put the string in quotes; e.g. 1r"written"," written" The reason why I didn't stick a ^Z there is because I wanted to get away from control characters in the commands, and a comma just looks better, IMHO.

I haven't used EDLIN in a LONG time (decades), but just did an experiment with MS-DOS 7.1 EDLIN. Your problem doesn't seem to be unrecognized spaces, it seems to be that you're not using any sort of "escape" character to separate your input and output strings. I believe you think the comma should be the "escape" character and it isn't. There's a similar issue with programs like SED and AWK/GAWK. When I'm in EDLIN (at least the one with comes with MD-SOD 7.1) and I type "?" to get help, the syntax for the Replace command looks like this: Replace [startline][,endline][?]R[oldtest][CTRL+Znewtest] It expects you to use a Ctrl-Z (end-of-file character) as the "escape" character. If I use the Ctrl-Z "trick" I can replace things like you're wanting to do. I do not remember if earlier versions of EDLIN did this or not, nor do I know how FD-EDLIN works. ___ Freedos-devel mailing list Freedos-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-devel
[Freedos-devel] Question about edlin
I actually do use edlin sometimes. But I have a question that might actually be a bug report: When I try to search and replace text, and I want to add a space in front of my replaced text, I can't get it to work. Am I doing this wrong? Here's an example: In this 1-line file, I want to edit the line from "..file,written.." to "..file, written.." (I want to add a space before the word "written") D:\DOCS>edlin t.txt edlin 2.23, copyright (c) 2003 Gregory Pietsch This program comes with ABSOLUTELY NO WARRANTY. It is free software, and you are welcome to redistribute it under the terms of the GNU General Public License -- either version 2 of the license, or, at your option, any later version. t.txt: New file. *i : This is a plain text file,written in edlin. : . *1rwritten, written *l 1:*This is a plain text file,written in edlin. * I'm using the "r" (replace) instruction correctly: 1rfrom,to will start at line 1 and replace "from" with "to". But it looks like a leading space is ignored, so edlin treats my "1rwritten, written" as just "1rwritten,written" and seems to ignore it because the "from" and "to" strings are the same. FYI: I can add a space in the middle of a replaced word, such as: *1rtext,te xt 1: This is a plain te xt file,written in edlin. Is "ignore leading spaces after the comma in the 'r' command" the expected behavior from MS-DOS edlin? ___ Freedos-devel mailing list Freedos-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-devel
