% if [[ -f  "$BUILD_SRC/Dockerfile" ]]; then
 .INCLUDE "$BUILD_SRC/Dockerfile"
% fi

if the file "$BUILD_SRC/Dockerfile" does not exist then the .INCLUDE statement is ignored BUT bash-tpl STILL seems to want to check that the .INCLUDE file exists thus throwing an error. This is unexpected.

File not found: '/data/Hacking/computing/docker/uci-docker-nextcloud/src/Dockerfile'
/dev/fd/63: line 142: syntax error near unexpected token `fi'
/dev/fd/63: line 142: `fi'

if "$BUILD_SRC/Dockerfile" exists it all works as expected.

Discussed in #5

Hello,

I'm using your project inside mine.
It is a kind of bash compiler (it aggregates several files together in order to generate a unique bash file).

bash-tpl is in the heart of this compiler, so this message is just to say thank you for your work.

I added a reference to your project here
https://github.com/fchastanet/bash-tools-framework#4-acknowledgements

kind regards,

Hi, nice work

Would it be possible to pass a format string to printf? Here's an example without

.DELIMS stmt-block="<% %>" tag="{{ }}"
<%
ENV_VARIABLE="$(printf "%17s" "$ENV_VARIABLE")"
name1="$(printf "%-13s" "$1")"
name2="$(printf "%-13s" "$2")"
%>


+---------------+---------+-------------------+
|               |         |                   |
+---------------+---------+-------------------+
| {{ $name1  }} | ....... | {{$ENV_VARIABLE}} |
| {{ $name2  }} | ....... | {{$ENV_VARIABLE}} |
+---------------+---------+-------------------+

and with,

.DELIMS tag="{{ }}"

+------------------+---------+-------------------+
|                  |         |                   |
+------------------+---------+-------------------+
| {{%-13s $1    }} | ....... | {{%17s $ENV_VARIABLE}} |
| {{%-13s $2    }} | ....... | {{%17s $ENV_VARIABLE}} |
+---------------+---------+-------------------+

For the code

RUN apt-get update && \
	apt-get -y install --no-install-recommends

… Bash-TPL generates:

printf "%s\n" RUN\ apt-get\ update\ \&\&\ \\
printf "%s\n" $'\tapt-get -y install --no-install-recommends'

Which prints

RUN apt-get update && \
$\tapt-get -y install --no-install-recommends

…when run with Dash.

As the readme says, the generated scripts are not supposed to use Bashisms.

The shell scripts that Bash-TPL generates are not intended to be Bash-specific.

The feature in question is, as far as I can tell, part of POSIX 2024, but it’ll be a while until support for it is added to all shells.
Dash has committed a patch that adds it just a few hours ago.

I’m not sure whether it’s worth fixing it, but I guess this behavior should be at least documented here on the bug tracker.

I have need to source bash-tpl and then run it later via its function main. But to do that without a namespace issue bash-tpl would have to adopt a namespace prefix and main would need to be renamed to btpl or bash-tpl

i.e.

function btpl() {

(return 0 2> /dev/null) || btpl "$@"

and then for all functions and their calls

btpl_somefunctionname

all this would not affect directly executing the script

This would allow bash-tpl to play nice with other sourced code that may already be in a shell session.

as it is when I install the script I have to use sed to make those change those.

sed -i 's/\bmain\b/btpl/g'

using sed to prefix all the functions is a bit harder (at least where they are called)

First, thanks for the great work on bash-tpl -- I've been using it to great effect when making some new static sites.

I ran across an issue recently -- it appears that .INCLUDE cannot be used with a variable to render another .tpl file dynamically (eg., .INCLUDE $1).

Bash version:
GNU bash, version 3.2.57(1)-release (arm64-apple-darwin22)

Repro steps:

1. Create a top-level "layout" file.

printf '<div class="container">\n  .INCLUDE $1\n</div>\n' > layout.tpl

Which produces:

<div class="container">
  .INCLUDE $1
</div>

2. Create a "partial" view file with some content

echo '<span>Subcontent should be displayed</span>' > partial.tpl

Which produces:

<span>Subcontent should be displayed</span>

3. Call bash-tpl

bash-tpl layout.tpl partial.tpl

This produces the following:

printf "%s\n" \<div\ class=\"container\"\>
  printf "%s\n" \ \ \</div\>

I expected this output:

printf "%s\n" \<div\ class=\"container\"\>
  printf "%s\n" \ \ Subcontent\ should\ be\ displayed
printf "%s\n" \</div\>

I would expect that the argument $1 could be used in the .INCLUDE directive to dynamically pass in the .tpl file that should be rendered. I also could be missing something straightforward here, in which case any insight would be appreciated.

If this is not currently a feature, having this ability in bash-tpl would be great.

You can add Adrian's tool pp to similar tools section.

description of pp:

pp

a preprocessor

pp allows embedding sh code in files of any type by nesting it inside the #!\n token, where \n is a new line. That means that if you'd like a simple loop or an if inside an HTML file for instance, you could use pp.

hi, thanks for a great project

i'm trying to use .INCLUDE inside a statement block but can't quite figure it out. is it supported?
