Re: [NTG-context] ASCII mode within \footnote
Hello, OK, thanks for reaction. One more example - \text instead of ascii mode: ---- \starttext \type{%@$} A\footnote{\type{*\$% }} B\footnote{\type{*\$\% }} \stoptext ---- gives: " *\$ *\$\% " in the footnote. IOW, I cannot simply print "%": "%" at the end yields "" whilst "\%" produces "\%". Is there a simple way to prinst simple "%"? (There is probably a more clumsy way - type \letterpercent instead of % - but this is a minimal sample; in my real sample there are many "%"s to be shown as "%".)

Hello,
the following code doesn't compile:

When the line with \footnote is commented, compilation works fine.
What's "evil" in \footnote{\startasciimode %@$\stopasciimode}?

Why not just use asciimode? To understand why \footnote{\type{...}}} doesn't work, you need to understand TeX's "digestive system". \type{...} (and asciimode) work by modifying the catcode tables. However, they are are used inside a footnote, the argument of \footnote is parsed according to the catcode table which is active when footnote is passed. Under the default catcode table, % is a comment, so when you type: \footnote{\type{*\$% }} the argument of \footnote is `\type{*\$}` So, if you want \footnote to "see" the %, you need to activate a catcode table where % is a letter. So, the simplest solution is to use \asciimode. Aditya
Hello Aditia, thanks for reaction. I simply want to write "%APPDATA%\file.txt" and the same into the footnote, with ability to use the text "%APPDATA%\file.txt" without any substitution (like "%" -> "\letterpercent") - if possible. My attepmts with \text or \asciimode fail: ---- \starttext \type{%APPDATA%\file.txt} \footnote{% %\type{%APPDATA%\file.txt} %\asciimode{%APPDATA%\file.txt} } \stoptext ---- Even plays with %\catcode\commentasciicode=\othercatcode %\catcode\backslashasciicode=\othercatcode don't give the desired result. So - is there a simple way how to get strings with "%" and "\" (which represent a path on Windows) into footnote? Best regards, Lukas On 2019-11-02 16:35, Aditya Mahajan wrote:

As Hans' mentioned, use: \startasciicode \footnote{\type{%APPDATA%\file.txt}} \stopasciicode Aditya

In a longer document setting \asciimode at the begin can be the better solution. The reason why setting \asciimode in the \footnote doesn't work is that TeX uses uses the meaning of a special character it had when it read the argument, i.e. when TeX reads the text "%APPDATA%\file.txt" the percent sign acts as begin of a comment and everything after it is ignored. As a result the asciimode command can't work because the text has already disappeared. Other characters like $ are less problematic because there are ways to change their meaning afterwards (# can be tricky) but not comments because nothing remains. \setupbuffer [before=\blank, after=\blank] \starttext Normal comment: \startbuffer % comment \stopbuffer \typebuffer \getbuffer Comment in \type{asciimode} environment: \startbuffer \startasciimode % comment \stopasciimode \stopbuffer \typebuffer \getbuffer Comment in the argument of a command: \startbuffer \firstofoneargument { % comment } \stopbuffer \typebuffer \getbuffer Comment in the argument of a command + \type{asciimode} in the argument: \startbuffer \firstofoneargument { \startasciimode % comment \stopasciimode } \stopbuffer \typebuffer \getbuffer Comment in a argument after \type{asciimode} was enabled: \startbuffer \startasciimode \firstofoneargument { % comment } \stopasciimode \stopbuffer \typebuffer \getbuffer \stoptext Wolfgang
Hello,
thanks Aditya and Wolfgang for "deep" explanation in several last mails.
We are approaching the goal...
Aditya's ocde:
---- \starttext \startasciimode \footnote{\type{%APPDATA%\file.txt}} \stopasciimode \stoptext ----
gives (in the footnote):
" 1 %APPDATA%\file .txt " ^ ............... +------ So there is ONE UNWANTED SPACE - how to make it disappear?
Thank you again for patience and best regards,
Lukas
When you use \type in the argument of another command there are some limitation in TeX and this is another one. The reason for the space is that TeX adds a space after a command when it reads the argument which will in this case appears in the output. When you use \type outside of the footnote this won't happens because \file in the argument is treated as a backslash followed by four single letters but in this case TeX handles it as the commend \file. Below is a simple example which demonstrates the behaviour, with the \detokenize command (nothing you need in a normal document) you can visualize TeX's behaviour. The second example shows another problematic characters. \starttext \type{\dummy.} \firstofoneargument{\type{\dummy.}} {\tt\detokenize{\dummy.}} \blank \type{#} \firstofoneargument{\type{#}} {\tt\detokenize{#}} \stoptext A way to avoid this problem is to use a slash a path separator instead of the backslash. Another way to get rid of it is to save the path a buffer and print the content of the buffer with the \typeinlinebuffer command. \starttext \startbuffer %APPDATA%\file.txt \stopbuffer \footnote{\typeinlinebuffer} \stoptext Wolfgang

Another option, if you have many such files is to define a macro: \define[1]\APPDATA{\mono{\letterpercent APPDATA\letterpercent\letterbackslash#1}} And then use: \footnote{\APPDATA{file.txt}} Aditya
