Cannot set/change user binary dir on Linux #365
Description
Activity
Hi,
I believe tinytex is only calling
tinytex::tlmgr_path()whenadd_path = TRUEin the install function. Thistlmgr_path()is a thin wrapper aroundtlmgr path addCLI command. Doc is here: https://www.tug.org/texlive/doc/tlmgr.html#pathOn Unix, adds or removes symlinks for executables, man pages, and info pages in the system directories specified by the respective options (see the "option" description above).
You can check the value of the option using
tinytex::tlmgr(c("option", "sys_bin"))or all options usingtinytex::tlmgr(c("option", "showall"))(or obviously directly in terminal withtlmgr)Which is the value set ?
I believe you can change this value quiet easily using
tlmgr option sys_bin <new value>ortinytex::tlmgr(c("option", "sys_bin", "<new_path>")This should change the behavior to the
tlmgr_path()function. So probably order would be- Install TinyTeX with
add_path = FALSE - Run
tinytex::tlmgr(c("options", "sys_bin", "<new_path>") - Run
tinytex::tlmgr_path()
So afterall it is a
tlmgrthing IMO.Hope it helps

Hi @cderv, thanks a lot for the detailed response!
Which is the value set ?
> tinytex::tlmgr(c("option", "sys_bin")) tlmgr option sys_bin Destination for symlinks for binaries (sys_bin): /home/salim/bin
I believe you can change this value quiet easily using
tlmgr option sys_bin <new value>ortinytex::tlmgr(c("option", "sys_bin", "<new_path>")Awesome, that worked!
I've proposed a new FAQ item in yihui/yihui.org#171 about this as well as yihui/yihui.org#172 :)
Reacted by Christophe DervieuxYes, on Linux, the
sys_binoption is currently set to~/binin the R function:
https://github.com/yihui/tinytex/blob/c3a71c782054e000949c42b1ec547d737e1d11bf/R/install.R#L404
and in the shell script:

~/.local/bininstead, but I just checked thePATHvariable on Ubuntu 20.04, and found that it did not contain~/.local/bin.~/binis still present inPATH. It seems that it's not a good idea to setsys_binto~/.local/binyet, otherwise users will have to adjustPATHmanually.@yihui Yes, I agree that it's too early to change the default. It's a recurring issue on Ubuntu and I don't know what their immediate plans are. Since Ubuntu uses systemd and systemd is a freedesktop.org project adhering to the XDG Base Directory Specification (easily verified by running
systemd-path user-binarieswhich should give/home/username/.local/bin), I think eventually they will make the switch.We could think about introducing an additional param
bin_diror the like intinytex::install_tinytex()but maybe it's not worth the hassle. I can live fine with the workaround outlined by @cderv.- added a commit that references this issue
on Apr 14, 2022 Okay, I just made a change so that
~/.local/binwill be used if it exists. The rationale is that this directory shouldn't exist by default. If it does, I assume that the user really prefers it over~/bin. That should fix your problem.Alternatively, I could check if
~/.local/binis present onPATHinstead of merely checking if this directory exists, but I guess the latter might be enough for *nix users.diff --git a/R/install.R b/R/install.R index 4d6ac31..65a2f49 100644 --- a/R/install.R +++ b/R/install.R @@ -411,7 +411,9 @@ install_prebuilt = function( # post-install configurations post_install_config = function(add_path, extra_packages, repo, hash = FALSE) { if (os_index == 2) { - if (!dir_exists(bin_dir <- '~/.local/bin')) dir.create(bin_dir <- '~/bin', FALSE, TRUE) + bin_dir = '~/.local/bin' + if (!path.expand(bin_dir) %in% env_paths()) bin_dir = '~/bin' + dir.create(bin_dir, FALSE, TRUE) tlmgr(c('option', 'sys_bin', bin_dir)) } # fix fonts.conf: https://github.com/yihui/tinytex/issues/313 @@ -430,6 +432,11 @@ post_install_config = function(add_path, extra_packages, repo, hash = FALSE) { } } +# get paths on the PATH variable +env_paths = function() { + unlist(strsplit(Sys.getenv('PATH'), .Platform$path.sep, fixed = TRUE)) +} + download_installer = function(file, version) { url = if (version != '') sprintf( 'https://github.com/yihui/tinytex-releases/releases/download/v%s/%s', version, file diff --git a/tools/install-bin-unix.sh b/tools/install-bin-unix.sh index b0a3393..f2bf897 100755 --- a/tools/install-bin-unix.sh +++ b/tools/install-bin-unix.sh @@ -60,10 +60,13 @@ fi cd $TEXDIR/bin/*/ +# if ~/.local/bin is on PATH, use it as sys_bin; otherwise use ~/bin BINDIR="$HOME/.local/bin" -if [ ! -d $BINDIR]; then +if [[ "$PATH" =~ (^|:)"${BINDIR}"(:|$) ]]; then +else BINDIR="$HOME/bin" fi +mkdir -p $BINDIR [ $OSNAME != "Darwin" ] && ./tlmgr option sys_bin $BINDIR ./tlmgr postaction install script xetex # GH issue #313
Alternatively, I could check if ~/.local/bin is present on PATH instead of merely checking if this directory exists, but I guess the latter might be enough for *nix users.
FWIW I would need to recheck but I think
~/.local/binis on PATH on Ubuntu inside GHA but not created.Reacted by Yihui Xie and luifrancgomReacted by luifrancgomOkay, if that's the case, my current fix should work, and the alternative fix could be problematic (would need to check for the existence of the dir or create the dir).
Okay, I just made a change so that

I just installed tinytex for the first time on a Linux system (Ubuntu 20.04). First of all: Great project, thank you!
Now to my problem: While it's possible to customize the tinytex installation path (aka tinytex "root") via
tinytex::install_tinytex()'sdirparam, there doesn't seem to exist any means to set/customize the user bin folder where tinytex places the symlinks after successful installation. Instead of the default~/binI'd like to use~/.local/bin(which is the default defined in the XDG Base Directory Specification).This wouldn't be that much of a problem if I could just manually move the symlinks and forget about it. But tinytex regenerates the
~/bindir with all symlinks everytimetinytex::tlmgr_install()is executed. Is there any environment variable I could set to avoid this? Or anything else I've missed?By filing an issue to this repo, I promise that
xfun::session_info('tinytex'). I have upgraded all my packages to their latest versions (e.g., R, RStudio, and R packages), and also tried the development version:remotes::install_github('yihui/tinytex').I understand that my issue may be closed if I don't fulfill my promises.
